Aliens Might Weigh As Much As Polar Bears And Be Taller Than The Tallest Man Who Ever Lived

April 11, 2015 / / 0 Comments





Excerpt from huffingtonpost.com

No one really knows whether we're alone or if the universe is brimming with brainy extraterrestrials. But that hasn't stopped scientists from trying to figure out what form intelligent aliens might take. 

And as University of Barcelona cosmologist Dr. Fergus Simpson argues in a new paper, most intelligent alien species would likely exceed 300 kilograms (661 pounds)--with the median body mass "similar to that of a polar bear."

If such a being had human proportions, Simpson told The Huffington Post in an email, it would be taller than Robert Wadlow, who at 8 feet, 11 inches is believed to have been the tallest human who ever lived.

robert wadlowRobert Wadlow (1918-1940), the tallest man who ever lived.


Simpson's paper, which is posted on the online research repository arXiv.org, is chockablock with formidable-looking mathematical equations. But as he explained in the email, his starting point was to consider the relationship between the number of individuals in a population on Earth and the body mass of those individuals:
"Ants easily outnumber us because they are small. Our larger bodies require a much greater energy supply from the local resources, so it would be impossible for us to match the ant population. Now apply this concept to intelligent life across the universe. On average, we should expect physically larger species to have fewer individuals than the smaller species. And, just like with countries, we should expect to be in one of the bigger populations. In other words, we are much more likely to find ourselves to be the ants among intelligent species."

Or, as Newsweek explained Simpson's argument, there are probably more planets with relatively small animals than planets with relatively large animals. It makes sense to assume that Earth is in the former category, so we can assume that humans are probably among the smaller intelligent beings.

What do other scientists make of Simpson's paper?

“I think the average size calculation is reasonable,” Dr. Duncan Forgan, an astrobiologist at the University of St. Andrews in Scotland who wasn't involved in the research, told Newsweek.
But to Dr. Seth Shostak, senior astronomer at the SETI Institute in Mountain View, Calif., the argument is suspect.

"There is an assumption here that intelligence can come in all (reasonable) sizes, and does so with more or less equal likelihood," Shostak told The Huffington Post in an email. "That may be true, but on Earth bigger has not always been better, at least in the brains department. Dolphins have higher IQs than whales, and crows are smarter than eagles. Octopuses are cleverer than giant squids, and obviously we’re smarter than polar bears."

Ultimately, Shostak said, we can’t know whether "little green men are actually big green men" before we actually make contact.
Until then!

Japanese scientists have successfully transmitted energy wirelessly in a breakthrough that could pave the way for space-based solar power systems.

Mitsubishi researchers used microwaves to deliver 1.8 kilowatts of power - enough to run an electric kettle - through the air with pinpoint accuracy to a receiver 170ft (55 metres) away.

While the distance was relatively small, the technology could someday pave the way for mankind to tap the vast amount of solar energy available in space and use it here on Earth.

'This was the first time anyone has managed to send a high output of nearly two kilowatts of electric power via microwaves to a small target, using a delicate directivity control device,' said a spokesman for the Japan Aerospace Exploration Agency (Jaxa) said.

The test, which took place at Kobe Shipyard & Machinery Works in Nagoya, Japan, will help Jaxa devise its long-awaited space solar power system.

Solar power generation in space has many advantages over its Earth-based cousin, notably the permanent availability of energy, regardless of weather or time of day.

While man-made satellites, such as the International Space Station, have long since been able to use the solar energy that washes over them from the sun, getting that power down to Earth where people can use it has been the thing of science fiction.

But the Japanese research offers the possibility that humans will one day be able to farm an inexhaustible source of energy in space.
The idea, said the Jaxa spokesman, would be for microwave-transmitting solar satellites - which would have sunlight-gathering panels and antennae - to be set up about 22,300 miles (36,000km) from the Earth.

'But it could take decades before we see practical application of the technology - maybe in the 2040s or later,' he said.

'There are a number of challenges to overcome, such as how to send huge structures into space, how to construct them and how to maintain them.'

The idea of space-based solar power generation emerged among US researchers in the 1960s and Japan's SSPS programme, chiefly financed by the industry ministry, started in 2009, he said.

COULD A SOLAR FARM IN SPACE POWER OUR FUTURE?

Space-based solar power – once the stuff of science-fiction – could be available sooner than expected if Japan has its way

Solar power has had a difficult start on Earth thanks to inefficient panels and high costs. But in space, scientists believe it could transform the way we generate energy.

Now, the space-based solar power – once the stuff of science-fiction – could be available sooner than expected if Japan has its way.

Within 25 years, the country plans to make space-based solar power a reality, according to a proposal from the Japan Aerospace Exploration Agency (Jaxa).

In a recent IEEE article by Susumu Sasaki, a professor emeritus at Jaxa, outlined the agency's plans create a 1.8 mile long (3 km) man-made island in the harbour of Tokyo Bay.

The island would be studded with 5 billion antennas working together to convert microwave energy into electricity.

The microwaves would be beamed down from a number of giant solar collectors in orbit 22,400 miles (36,000 km) above the Earth. 
Resource-poor Japan has to import huge amounts of fossil fuel.
It has become substantially more dependent on these imports as its nuclear power industry shut down in the aftermath of the disaster at Fukushima in 2011.

In a separate project, a Japanese firm last year revealed plans to cover the moon in a huge swathe of solar panels and use them to power homes here on Earth.

Shimizu Corporation's Luna Ring project would stretch almost 6,790 miles (11,000km) around the moon's equator and a field of solar panels would form a belt.

Energy captured by these panels would then be sent to Earth using microwaves and laser lights could be beamed directly to countries where it is needed.

According to the plans, the project would produce around 13,000 terrawatts of continuous solar energy. At present, the world's population consumes about 15 terawatts of power each year.

The company claims the plans would not only provide an 'almost inexhaustible' energy supply, it would stop the rise of global warming caused by carbon dioxide from current energy sources.

Monster Black Hole’s Mighty Belch Could Transform Our Entire Galaxy

February 19, 2015 / / 0 Comments

This artist's illustration depicts the furious cosmic winds streaming out from a monster supermassive black hole as detected by NASA's NuSTAR space telescope and the European Space Agency's XMM-Newton X-ray observatory.
This artist's illustration depicts the furious cosmic winds streaming out from a monster supermassive black hole as detected by NASA's NuSTAR space telescope and the European Space Agency's XMM-Newton X-ray observatory.


Except from space.com

A ravenous, giant black hole has belched up a bubble of cosmic wind so powerful that it could change the fate of an entire galaxy, according to new observations.
Researchers using two X-ray telescopes have identified a cosmic wind blowing outward from the supermassive black hole at the center of galaxy PDS 456. Astronomers have seen these winds before, but the authors of the new research say this is the first observation of a wind moving away from the center in every direction, creating a spherical shape.
The wind could have big implications for the future of the galaxy: It will cut down on the black hole's food supply, and slow star formation in the rest of the galaxy, the researchers said. And it's possible that strong cosmic winds are a common part of galaxy evolution — they could be responsible for turning galaxies from bright, active youngsters to quiet middle-agers. 

Big eater

The supermassive black hole at the center of PDS 456 is currently gobbling up a substantial amount of food: A smorgasbord of gas and dust surrounds the black hole and is falling into the gravitational sinkhole.
As matter falls, it radiates light. The black hole at the center of PDS 456 is devouring so much matter, that the resulting radiation outshines every star in the galaxy. These kinds of bright young galaxies are known as quasars: a galaxy with an incredibly bright center, powered by a supermassive black hole with a big appetite.
New observations of PDS 456 have revealed a bubble of gas moving outward, away from the black hole. Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton, the authors of the new research imaged the galaxy on five separate occassions in 2013 and 2014. The researchers say they can show that the photons of light emitted by the in-falling matter are pushing on nearby gas, creating the wind.
Scientists have studied these cosmic winds before, but the authors of the new research say their work goes a step further.
"It tells us that the shape of the wind is not just a narrow beam pointed in our direction. It is really a wind that is flowing in every direction away from the black hole," said Emanuele Nardini, a postdoctoral researcher at Keele University in Staffordshire, England. "With a spherical wind, the amount of mass it carries out is much larger than just a narrow beam."
According to a statement from NASA, galaxy PDS 456 "sustains winds that carry more energy every second than is emitted by more than a trillion suns." Such powerful winds could change the entire landscape of PDS 456, the researchers say. First, the wind will blow through the disk of matter surrounding the black hole — this disk currently serves as the black hole's food supply. The cosmic wind created by the black hole's appetite could significantly reduce or destroy the disk. In other words, the black hole cannot have its cake and eat it, too. 

Bright young things

With no matter left to fall into the black hole, the radiation would cease as well. The brilliant center of the quasar will dim. By diminishing the black hole's food supply, they may turn quasars and other "active galaxies" like PDS 456 into quiescent galaxies like the Milky Way. Theorists have proposed that cosmic winds could explain why there are more young active galaxies than old active galaxies.
"We know that in almost every galaxy, a supermassive black hole resides in the center," said Nardini. "But, most of the galaxies we see today are quiescent, they are not active in any way. The fact that galaxies today are quiescent — we have to find an explanation for that in something that happened a long time ago."
In addition to quenching the radiation from an active black hole, these cosmic winds may slow down star formation in galaxies. The cosmic wind could blow through regions thick with gas and dust, where young stars form, and thin out the fertile stellar soil.
"If you have a black hole with this kind of wind, in millions of years [the winds] will be able to quench star formation and create a galaxy like our own," Nardini said. Stars will still form in the Milky Way, but not at the high rate of many young galaxies.
It's possible that these cosmic winds are a central reason why most galaxies go from being brightly burning active youngsters to quiet middle-agers.

Must-See Geminid Meteor Shower Peaks This Weekend: An Observer’s Guide

December 16, 2014 / / 0 Comments



2014 Geminid Meteor Shower Sky Map


Excerpt from
space.com

 The spectacular Geminid Meteor shower hits peak activity this weekend. Though competing with some unfortunate moonlight, the shower still should make for a must-see astronomical event.

While moonlight will somewhat hinder this year's Geminid meteor shower, intrepid observers with good weather and low light pollution should still be able to catch a good meteor show Saturday (Dec. 13) night.

"If you have not seen a mighty Geminid fireball arcing gracefully across an expanse of sky, then you have not seen a meteor," note astronomers David Levy and Stephen Edberg. 


Even if you can't see the meteor display from your part of the world, you can watch them online. The online Slooh Community Observatory will host a live webacst of the Geminid meteor display on Saturday night beginning at 8 p.m. EST (0100 Dec. 14 GMT).You can also watch the Slooh webcast directly:http://live.slooh.com/. NASA meteor expert Bill Cooke will also host a live Geminids webchat on Saturday night from 11 p.m. to 3 a.m. EST (0400 to 0800 GMT), as well as a live webcast.
You can watch the webcasts of the Geminid shower live on Space.com, starting at 8 p.m. EST, courtesy of Slooh and NASA. The Italy-based Virtual Telescope Project will also host a Geminds webcast, beginning at 9 p.m. EST (0200 GMT).

Although the bright moon will be high in the sky by 11:30 p.m. local time Saturday (Dec. 13) (during the shower's peak), skywatchers can still catch a potentially incredible show before the moon creeps above the horizon, washing out the sky. Stargazers might be able to see an average of one or two Geminid meteors per minute Saturday before the moon rises.

By around 9 p.m., the constellation Gemini — the part of the sky where the meteors seem to emanate from — will have climbed more than one-third of the way up from the horizon. Meteor sightings should begin to really increase noticeably thereafter. By around 2 a.m., the last-quarter moon will be low in the east-southeast, but Gemini will stand high overhead. So you might still see a good number of meteors in spite of the moon's presence.

A brilliant shower

The Geminids are, for those willing to brave the chill of a December night, a very fine winter shower, and usually the most satisfying of all the annual showers. They can even surpass the brilliant August Perseid meteor shower.

Studies of past displays show that the Geminid shower is rich both in slow, bright, graceful meteors and fireballs, as well as in faint meteors, with relatively fewer objects of medium brightness. Many Geminids appear yellowish in hue; some even appear to form jagged or divided paths.     

These meteors travel at a medium speed and appear to emanate, specifically, from near the bright star Castor, in the constellation of Gemini, the Twins, hence the name "Geminid." In apparent size, that's less than half the width of the moon. As such, this is a rather sharply defined radiant as most meteor showers go. It suggests the stream is "young," perhaps only several thousand years old.

Generally speaking, depending on your location, Castor begins to come up above the east-northeast horizon right around the time evening twilight comes to an end. As the Gemini constellation begins to climb the eastern sky just after darkness falls, there is a fair chance of perhaps catching sight of some "Earth-grazing" meteors. Earthgrazers are long, bright shooting stars that streak overhead from a point near to even just below the horizon. Such meteors are so distinctive because they follow long paths nearly parallel to the Earth's atmosphere. 

Because Geminid meteoroids are several times denser than the comet dust that supply most meteor showers and because of the relatively slow speed with which the Geminids encounter Earth (22 miles or 35 kilometers per second), these meteors appear to linger a bit longer in view than most. As compared to an Orionid or Leonid meteor that can whiz across your line of sight in less than a second, a Geminid meteor moves only about half as fast. Personally, their movement reminds me of field mice scooting from one part of the sky to another.
