Are Aliens Finding Ways to Communicate With Humans From Deep Space? NASA intercepts strange “Alien Sounds”




dailytimesgazette.com


The recent alien hunting projects of several teams might be another failure, but some unusual sounds were captured by a balloon experiment set up by NASA, which they think could possibly come from another alien life.

The balloon carries an infrasound microscope that is able to record sound waves in the atmosphere at frequencies lower than 20 hertz. The device is floating just 22 miles above the Earth when it picked up the strange sound.

It was Daniel Bowman, a student from the University of North Carolina, who designed and built the balloon equipment used in the study. The initial program managed by NASA and the Louisiana Space Consortium tested the flight of the equipment where they captured sounds from the atmosphere of Arizona and New Mexico. 
It was just one of the ten experiments flown atop of the High Altitude Student Platform that successfully picked up the sounds. 
The said program was able to launch more than 70 student experiments in search of a successful project since 2006.

As that one balloon fly over the height of 37,500 meters above Earth for 9 hours, which is just below the top of the stratosphere and higher than the flight height of airplanes, it got the record of the highest point an equipment carrying infrasound has ever reached.

But the record is not all that, the sound captured by the balloon is what researchers claimed as a signal that they never encountered before.

As Bowman has said, “It sounds kind of like ‘The X-Files’.” There is some possibility that the sound might have come from another alien life, but may also originate from wind farms, crashing ocean waves, atmospheric turbulence, gravity waves, and vibrations formed by the balloon cable.

Bowman reported, “I was surprised by the sheer complexity of the signal. I expected to see a few little stripes,” as he was pertaining to the visual representation of the sounds through spectrogram detailing. The frequency range below 20 hertz is not audible to human hearing frequency, so the team adjusted it faster during the analysis.

He added, “There haven’t been acoustic recordings in the stratosphere for 50 years. Surely, if we place instruments up there, we will find things we haven’t seen before.”

Infrasound carried at great distances from its source is usually formed by low-frequency wave-creating phenomenon, such as earthquakes, volcanic eruptions, thunderstorms and meteor showers. Scientists have long used infrasound detectors to monitor weather and geologic activity all over the planet. NASA also plans to use infrasound detectors on the much-awaited Mars mission.

Excerpt from smh.com.au

A team of astronomers peering deep into the heavens have discovered the earliest, most distant galaxy yet, just 670 million years after the Big Bang.

Astronomers have discovered a baby blue galaxy that is the furthest away in distance and time - 13.1 billion years - that they’ve ever seen.
Close-up of the blue galaxy

The findings, described in Astrophysical Journal Letters, reveal a surprisingly active, bright galaxy near the very dawn of the cosmos that could shed light on what the universe, now 13.8 billion years old, was really like in its young, formative years.

"We're actually looking back through 95 per cent of all time to see this galaxy," said study co-author Garth Illingworth, an astronomer at the University of California, Santa Cruz.

"It's really a galaxy in its infancy ... when the universe was in its infancy."

Capturing an image from a far-off light source is like looking back in time. When we look at the sun, we're seeing a snapshot of what it looked like eight minutes ago.

The same principle applies for the light coming from the galaxy known as EGS-zs8-1. We are seeing this distant galaxy as it existed roughly 13.1 billion years ago.

EGS-zs8-1 is so far away that the light coming from it is exceedingly faint. And yet, compared with other distant galaxies, it is surprisingly active and bright, forming stars at roughly 80 times the rate the Milky Way does today.

This precocious little galaxy has built up the mass equivalent to about 8 billion suns, more than 15 per cent of the mass of the Milky Way, even though it appears to have been in existence for a mere fraction of the Milky Way's more than 13 billion years.

"If it was a galaxy near the Milky Way [today], it would be this vivid blue colour, just because it's forming so many stars," Illingworth said.

One of the many challenges with looking for such faint galaxies is that it's hard to tell if they're bright and far, or dim and near. Astronomers can usually figure out which it is by measuring how much that distant starlight gets stretched, "redshifted", from higher-energy light such as ultraviolet down to optical and then infrared wavelengths. The universe is expanding faster and faster, so the further away a galaxy is, the faster it's going, and the more stretched, or "redder", those wavelengths of light will be.

The astronomers studied the faint light from this galaxy using NASA's Hubble and Spitzer space telescopes. But EGS-zs8-1 seemed to be too bright to be coming from the vast distances that the Hubble data suggested.

To narrow in, they used the MOSFIRE infrared spectrograph at the Keck I telescope in Hawaii to search for a particularly reliable fingerprint of hydrogen in the starlight known as the Lyman-alpha line. This fingerprint lies in the ultraviolet part of the light spectrum, but has been shifted to redder, longer wavelengths over the vast distance between the galaxy and Earth.

It's a dependable line on which to base redshift (and distance) estimates, Illingworth said - and with that settled, the team could put constraints on the star mass, star formation rate and formation epoch of this galaxy.

The telltale Lyman-alpha line also reveals the process through which the universe's haze of neutral hydrogen cleared up, a period called the epoch of reionisation. As stars formed and galaxies grew, their ultraviolet radiation eventually ionised the hydrogen and ended the "dark ages" of the cosmos.

Early galaxies-such as EGS-zs8-1 - are "probably the source of ultraviolet radiation that ionised the whole universe", Illingworth said.

Scientists have looked for the Lyman-alpha line in other distant galaxies and come up empty, which might mean that their light was still being blocked by a haze of neutral hydrogen that had not been ionised yet.

But it's hard to say with just isolated examples, Illingworth pointed out. If scientists can survey many galaxies from different points in the universe's very early history, they can have a better sense of how reionisation may have progressed.

"We're trying to understand how many galaxies do have this line - and that gives us some measure of when the universe itself was reionised," Illingworth said.

"One [galaxy] is interesting, but it's when you have 50 that you can really say something about what galaxies were really like then."
As astronomers push the limits of current telescopes and await the completion of NASA's James Webb Space Telescope, set for launch in 2018, scientists may soon find more of these galaxies even closer to the birth of the universe than this new record breaker.

"You don't get to be record holder very long in this business," Illingworth said, "which is good because ultimately we are trying to learn about the universe. So more is better."

Astronomers Measure Distance to Farthest Galaxy Yet

Excerpt from nytimes.com

Leapfrogging backward in time to when the universe was apparently feeling its oats, a group of astronomers reported Tuesday that they had measured a bona fide distance to one of the farthest and thus earliest galaxies known.

The galaxy, more than a few billion light-years on the other side of the northern constellation Boötes, is one of the most massive and brightest in the early universe and goes by the name of EGS-zs8-1. 
It flowered into stardom only 670 million years after the Big Bang.
The light from that galaxy has taken 13 billion years to reach telescopes on Earth. By now, however, since the universe has continued to expand during that time, the galaxy is about 30 billion light-years away, according to standard cosmological calculations.
The new measurements allow astronomers to see the galaxy in its infancy. Despite its relative youth, however, it is already about one-sixth as massive as the Milky Way, which is 10 billion years old. And it is getting bigger, making stars 80 times faster than the Milky Way is making them today. The discovery was reported in The Astrophysical Journal by Pascal Oesch of Yale University and his colleagues.

By the rules of the expanding universe, the farther away a galaxy is, the faster it is retreating from us, measured by the “redshift” of its light being broadened to longer wavelengths, the way an ambulance siren seems to lower its pitch as it goes by.

In the past few years, as astronomers have raced one another into the past with instruments like the Hubble Space Telescope, galaxies have been found that appear even more distant. Those measurements, however, were estimates based on the colors of the objects — so-called photometric redshifts.

The new galaxy stuck out in a survey of distant galaxies by the Hubble and Spitzer space telescopes known as Candels, for Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. Its redshift was precisely measured with a powerful spectrograph known as Mosfire — Multi-Object Spectrometer for Infrared Exploration — on Keck 1, one of a pair of 10-meter-diameter telescopes on Mauna Kea in Hawaii. That makes it the highest redshift confirmed in this way, said Garth Illingworth, of the University of California, Santa Cruz, one of the astronomers in the study.

How galaxies were able to form and grow so rapidly after the lights came on in the universe is a mystery that will be addressed by a coming generation of instruments like the James Webb Space Telescope and the Thirty Meter Telescope, a goliath planned for Mauna Kea, already home to a dozen telescopes.

Recently, however, construction of the Thirty Meter Telescope, a $1.4 billion project, has been halted by protests by Hawaii residents who feel their mountain has been abused. An echo of that controversy appears in the new paper, in which Dr. Oesch and his colleagues write: “The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.”

Tesla to unveil ‘mystery’ life changing product tonight!



Tesla's expected home battery announcement could spark energy revolution. SolarCity has already installed 300 Tesla-made batteries in California homes.


 Excerpt from CBC News 

Tesla CEO Elon Musk is set to make an announcement later tonight. There's been speculation that a large-scale battery announcement is expected, but it's not clear if that will be the case.



The man behind the electric car revolution is expected to unveil a large-scale battery capable of powering an entire house, during an announcement at Tesla Motors headquarters in Hawthorne, Calif.
While the battery will likely slash power bills for consumers, some say it's also a move toward democratizing energy systems.

Elon Musk, CEO of Tesla Motors, teased the announcement on Twitter a month ago, saying a major new Tesla product line will be unveiled at Hawthorne Design Studio at 8 p.m. local time Thursday. "Not a car," he wrote, sparking speculation that it may be a home battery.

Musk, who moved to Canada from South Africa and who briefly studied at Queen's University in Kingston, Ont., before transferring to the University of Pennsylvania, is also chairman of SolarCity, a solar power provider.

SolarCity has already run a pilot program where it installed 300 home batteries made by Tesla in California homes. Another 130 systems were being installed in early 2015, according to the company's website.

The product will be available again in late summer, the company says, as it's working on "the next phase" of the program.

Tesla is also in the midst of building its gigafactory, which has added to the speculation that the company is unveiling a home battery. Musk says that by 2020, the factory will produce more lithium-ion batteries than all the current factories producing them today. 

A home battery attaches to a home's electrical system and collects energy gathered by solar panels when the sun is out, Michael Ramsey, a Wall Street Journal automotive reporter, told CBC's The Current. That energy can then be used when the sun is no longer out.
'This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building.'-— Warren Mabee, of Queen's University
"The idea is that you purchase this system and it allows you effectively to cut the cord," he says of a consumer's ability to forgo energy from the grid. The consumer's electricity bills would be significantly reduced because they would be paying for less electricity from the grid.

This innovation could move the world toward a future where power is generated where we need it and where we use it, says Warren Mabee, director of the Queen's Institute for Energy and Environmental Policy.

"This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building," Mabee says.

In this system, centralized power generation becomes more of a backup than a driver, he says.

Costs remain high

However, the current systems are still very expensive, says Ramsey. The 300 home batteries installed in California cost upward of $20,000, he says.

"It would take years and years and years to cover the utility costs," he says. "It doesn't make sense unless the costs come down."

Ramsey views businesses as having the highest possible economic advantage from this development. The battery could offer businesses a surge of electricity when they have a high demand for power and cut their bills.

Mabee compares the cost of solar panels to cellphones. Smartphones were once very expensive, but each new generation has brought the cost down, he said.

Each year, solar panels become better and cheaper. Solar panels are getting close to their grid parity moment — when the cost of generating solar power is the same or cheaper than buying energy off the grid.

Another grid parity moment may be close, says Mabee. It won't be long before the cost of a solar panel and battery system will match the cost of purchasing electricity from the grid, he estimates.
"That magic grid parity moment is coming faster and faster," he said.

This revolutionary discovery could help scientists see black holes for the first time


supermassive black hole
Artist's concept of the black hole.



Excerpt from finance.yahoo.com
Of all the bizarre quirks of nature, supermassive black holes are some of the most mysterious because they're completely invisible.
But that could soon change.
Black holes are deep wells in the fabric of space-time that eternally trap anything that dares too close, and supermassive black holes have the deepest wells of all. These hollows are generated by extremely dense objects thousands to billions of times more massive than our sun.
Not even light can escape black holes, which means they're invisible to any of the instruments astrophysicists currently use. Although they don't emit light, black holes will, under the right conditions, emit large amounts of gravitational waves — ripples in spacetime that propagate through the universe like ripples across a pond's surface.
And although no one has ever detected a gravitational wave, there are a handful of instruments around the world waiting to catch one.

Game-changing gravitational waves



.

This illustration shows two spiral galaxies - each with supermassive black holes at their center - as they are about to collide. 

Albert Einstein first predicted the existence of gravitational waves in 1916. According to his theory of general relativity, black holes will emit these waves when they accelerate to high speeds, which happens when two black holes encounter one another in the universe.  

As two galaxies collide, for example, the supermassive black holes at their centers will also collide. But first, they enter into a deadly cosmic dance where the smaller black hole spirals into the larger black hole, moving increasingly faster as it inches toward it's inevitable doom. As it accelerates, it emits gravitational waves.
Astrophysicists are out to observe these waves generated by two merging black holes with instruments like the Laser Interferometer Gravitational-Wave Observatory.
"The detection of gravitational waves would be a game changer for astronomers in the field," Clifford Will, a distinguished profess of physics at the University of Florida who studied under famed astrophysicist Kip Thorne told Business Insider. "We would be able to test aspects of general relativity that have not been tested."
Because these waves have never been detected, astrophysicists are still trying to figure out how to find them. To do this, they build computer simulations to predict what kinds of gravitational waves a black hole merger will produce. 

Learn by listening

In the simulation below, made by Steve Drasco at California Polytechnic State University (also known as Cal Poly), a black hole gets consumed by a supermassive black hole about 30,000 times as heavy.
You'll want to turn up the volume.
What you're seeing and hearing are two different things.
The black lines you're seeing are the orbits of the tiny black hole traced out as it falls into the supermassive black hole. What you're hearing are gravitational waves.
"The motion makes gravitational waves, and you are hearing the waves," Drasco wrote in a blog post describing his work.
Of course, there is no real sound in space, so if you somehow managed to encounter this rare cataclysmic event, you would not likely hear anything. However, what Drasco has done will help astrophysicists track down these illusive waves.

Just a little fine tuning 

Gravitational waves are similar to radio waves in that both have specific frequencies. On the radio, for example, the number corresponding to the station you're listening to represents the frequency at which that station transmits.

Right now, astrophysicists only have an idea of what frequencies two merging black holes transmit because they’re rare and hard to find. In fact, the first ever detection of an event of this kind was only announced this month. 

Therefore, astrophysicists are basically toying with their instruments like you sometimes toy with your radio to find the right station, except they don’t know what station will give them the signal they’re looking for.
What Drasco has done in his simulation is estimate the frequency at which an event like this would produce and then see how that frequency changes, so astrophysicists have a better idea of how to fine tune their instruments to search for these waves.
Detecting gravitational waves would revolutionize the field of astronomy because it would give observers an entirely new way to see the universe. Armed with this new tool, they will be able to test general relativity in ways never before made possible.

Is In-Flight Refueling Coming to Commercial Airlines?




Excerpt from space.com

This article was originally published on The Conversation. The publication contributed this article to Space.com's Expert Voices: Op-Ed & Insights.

There’s real pressure on the aviation industry to introduce faster, cheaper and greener aircraft, while maintaining the high safety standards demanded of airlines worldwide.

Airlines carry more than three billion passengers each year, which presents an enormous challenge not only for aircraft manufacturers but for the civil aviation infrastructure that makes this extraordinary annual mass-migration possible. Many international airports are close to or already at capacity. The International Air Transport Association (IATA) has estimated that, without intervention, many global airports – including major hubs such as London Heathrow, Amsterdam Schiphol, Beijing and Dubai – will have run out of runway or terminal capacity by 2020. 


The obvious approach to tackling this problem is to extend and enlarge airport runways and terminals – such as the long-proposed third runway at London Heathrow. However there may be other less conventional alternatives, such as introducing in-flight refuelling for civil aircraft on key long-haul routes. Our project, Research on a Cruiser-Enabled Air Transport Environment (Recreate), began in 2011 to evaluate whether this was something that could prove a viable, and far cheaper, solution.

If in-flight refuelling seems implausible, it’s worth remembering that it was first trialed in the 1920s, and the military has continued to develop the technology ever since. The appeal is partly to reduce the aircraft’s weight on take-off, allowing it to carry additional payload, and partly to extend its flight range. Notably, during the Falklands War in 1982 RAF Vulcan bombers used in-flight refuelling to stage what was at the time the longest bombing mission ever, flying 8,000 miles non-stop from Ascension Island in the South Atlantic to the Falklands and back.

Reducing take-off weight could offer many benefits for civilian aircraft too. Without the need to carry so much fuel the aircraft can be smaller, which means less noise on take-off and landing and shorter runways. This opens up the network of smaller regional airports as new potential sites for long-haul routes, relieving pressure on the major hubs that are straining at the seams.

There are environmental benefits too, as a smaller, lighter aircraft requires less fuel to reach its destination. Our initial estimates from air traffic simulations demonstrate that it’s possible to reduce fuel burn by up to 11% over today’s technology by simply replacing existing global long-haul flight routes with specifically designed 250-seater aircraft with a range of 6,000nm after one refuelling – roughly the distance from London to Hong Kong. This saving could potentially grow to 23% with further efficiencies, all while carrying the same number of passengers the same distance as is possible with the current aircraft fleet, and despite the additional fuel burn of the tanker aircraft.

Tornado fighter jets in-flight refuel
Imagine if these Tornado fighter jets were 250-seater passenger aircraft and you’ve got the idea.

However, this is not the whole picture – in-flight refuelling will require the aerial equivalent of petrol stations in order to deliver keep passenger aircraft in the sky. With so much traffic it simply wouldn’t be possible to refuel any aircraft any time, anywhere it was needed. The location of these refuelling zones, coupled with the flight distance between the origin and destination airports can greatly affect the potential benefits achievable, possibly pulling flights away from their shortest route, and even making refuelling on some routes impossible – if for example the deviation to the nearest refuelling zone meant burning as much fuel as would have been saved.

Safety and automation

As with all new concepts – particularly those that involve bringing one aircraft packed with people and another full of fuel into close proximity during flight – it’s quite right to ask whether this is safe. To try and answer this question, the Dutch National Aerospace Laboratory and German Aerospace Centre used their flight simulators to test the automated in-flight refuelling flight control system developed as part of the Recreate project.

One simulator replicated the manoeuvre from the point of view of the tanker equipped with an in-flight refuelling boom, the other simulated the aircraft being refuelled mid-flight. Critical test situations such as engine failure, high air turbulence and gusts of wind were simulated with real flight crews to assess the potential danger to the operation. The results were encouraging, demonstrating that the manoeuvre doesn’t place an excessive workload on the pilots, and that the concept is viable from a human as well as a technical perspective.

So far we’ve demonstrated the potential aerial refuelling holds for civilian aviation, but putting it into practice would still pose challenges. Refuelling hubs would need to be established worldwide, shared between airlines. There would need to be fundamental changes to airline pilot training, alongside a wider public acceptance of this departure from traditional flight operations.

However, it does demonstrate that, in addition to all the high-tech work going into designing new aircraft, new materials, new engines and new fuels, the technology we already have offers solutions to the long-term problems of ferrying billions of passengers by air around the world.
