Astronomers Giddy Over What They Call A Cosmic ‘Dinosaur Egg’ About To Hatch

May 9, 2015 / / 0 Comments



cosmic dinosaur egg
The Antennae galaxies, shown in visible light in a Hubble image (upper image), were studied with ALMA, revealing extensive clouds of molecular gas (center right image). One cloud (bottom image) is incredibly dense and massive, yet apparently star free, suggesting it is the first example of a prenatal globular cluster ever identified.


Excerpt from huffingtonpost.com

A dense cloud of gas 50 million light-years away has astronomers buzzing, and they're using all sorts of strange metaphors to get the rest of us to pay attention.

They've discovered what they think may be a globular cluster -- a big ball of up to one million stars -- on the verge of being born.

“This remarkable object looks like it was plucked straight out of the very early universe," Dr. Kelsey Johnson, an astronomer at the University of Virginia in Charlottesville and lead author on a paper about the research, said in a written statement. "To discover something that has all the characteristics of a globular cluster, yet has not begun making stars, is like finding a dinosaur egg that’s about to hatch.”

Johnson and her colleagues spotted the bizarre object, which they call the "Firecracker," using the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama desert in Chile. It's located inside a pair of interacting galaxies known to scientists as NGC 4038/NGC 4039, or The Antennae Galaxies.

The Firecracker has a mass that's 50 times that of our sun, and is under an enormous amount of pressure -- roughly 10,000 times greater than the average pressure in interstellar space. According to the researchers, this makes it a good candidate for collapsing into a globular cluster within the next million years.

What do other scientists make of the discovery? Dr. Alison Peck, ALMA scientist at the National Radio Astronomy Observatory, who was not involved in the new research, called it "important" and said she was "really excited to hear about these results."
She told The Huffington Post in an email:
"One of the things that we all yearn to understand is how our surroundings formed, how our galaxy and our solar system came to be. To do this, since we can’t actually watch things change over time, (it just takes too long), we need to find similar objects at different stages of development and compare them. What Dr. Johnson’s team have found here is an analog of an object that we look for in the very early universe, but they’ve found it so close by that we’ll be able to make extremely detailed observations and find out much more about the physical conditions in this exciting region."
The research is set to be published in the Astrophysical Journal.

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.”

Water may have been abundant a short billion years after Big Bang

May 4, 2015 / / 0 Comments





Excerpt from thespacereporter.com

The formation of water vapor after the Big Bang was constrained by the lack of oxygen; it and other elements heavier than hydrogen and helium were created only later on, in the death throes of the first generation of massive stars. Oxygen created by the demises of early stars was swept out in to space by the explosions of supernovae and stellar winds, eventually joining with hydrogen to form water.

This process created islands of gas replete with heavy elements, such as oxygen; these regions were more bereft of oxygen than gaseous regions in the modern Milky Way galaxy. However, a new study by Tel Aviv University and the Harvard-Smithsonian Center for Astrophysics (CfA) has determined that, in certain islands, water vapor might have been as plentiful as it is today, only a billion years after the Big Bang.

According to a CfA statement, the researchers looked at whether water could form in the primordial molecular clouds, which were deficient in oxygen. Their analysis indicated that large quantities of water could form at around 80 degrees Fahrenheit. Water molecules would have been shattered by ultraviolet light emitted by stars; however, after hundreds of millions of years, an equilibrium between water creation and destruction would be reached.

“We looked at the chemistry within young molecular clouds containing a thousand times less oxygen than our Sun. To our surprise, we found we can get as much water vapor as we see in our own galaxy,” said astrophysicist Avi Loeb of CfA.

The new study has been accepted for publication in the Astrophysical Journal and is accessible online.

NASA’s Messenger Spacecraft Crashes Into Mercury, Captures Stunning Shots Before Demise

May 2, 2015 / / 0 Comments


Mercury


Excerpt from malaysiandigest.com


NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.





“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”






But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.





Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.
io9 reports that the spacecraft, which was the first to orbit Mercury, captured some 270,000 images of the planet during its four-year mission. The website also said the impact will create a 52-foot-wide crater in Mercury’s surface.


The spacecraft made several big discoveries during its mission, including the presence of ice in some dark craters near the poles, according to The New York Times. That’s pretty big news on a planet that reaches temperatures as high as 800 degrees Fahrenheit during the day.


The mission ended, according to NASA, because the spacecraft’s thrusters have run out of fuel.
