Astronomers have discovered a dust-filled ancient galaxy from the very early universe, which debunks earlier theories that earliest galaxies had no dust but gas. Astronomers from the University of Copenhagen used the Very Large Telescope’s X-shooter instrument along with the Atacama Large Millimeter/submillimeter Array and discovered a galaxy, named Galaxy A1689-zD1, which is an ancient galaxy and far from Earth.
The astronomers stated that the galaxy which
they were surprised to discover is far more evolved system than expected. It had a fraction of dust similar to a very mature galaxy, such as the Milky Way. Such dust is vital to life, because it helps form planets, complex molecules and normal stars.
According to the astronomers A1689-zD1 is only observable by virtue of its brightness being amplified more than nine times by a gravitational lens in the form of the spectacular galaxy cluster. Without the gravitational boost, the glow from this very faint galaxy would have been too weak to detect.
The astronomers stated that they are viewing A1689-zD1 when the Universe was only about 700 million years old, which is 5% of its present age. According to them, it is a relatively modest system — much less massive and luminous than many other objects that have been studied before at this stage in the early universe and hence a more typical example of a galaxy at that time.
A1689-zD1 is being observed as it was during the period of reionization, when the earliest stars brought with them a cosmic dawn, illuminating for the first time an immense and transparent universe and ending the extended stagnation of the Dark Ages. Expected to look like a newly formed system, the galaxy surprised the observers with its rich chemical complexity and abundance of interstellar dust.
Dust plays an extremely important role in the universe – both in the formation of planets and new stars.
Darach Watson, Associate Professor at Dark Cosmology Centre, University of Copenhagen, and the lead author of the study, said, “After confirming the galaxy’s distance using the VLT we realized it had previously been observed with ALMA. We didn’t expect to find much, but I can tell you we were all quite excited when we realized that not only had ALMA observed it, but that there was a clear detection. One of the main goals of the ALMA Observatory was to find galaxies in the early Universe from their cold gas and dust emissions — and here we had it!”
The researchers hope that future observations of a large number of distant galaxies could help unravel how frequently such evolved galaxies occur in this very early epoch of the history of the universe.

Excerpt from nbcnews.com
The military weather satellite that exploded in orbit last month apparently died of old age, U.S. Air Force officials say.
While investigators continue to study the dramatic Feb. 3 death of Defense Meteorological Satellite Program Flight 13 (DMSP-F13), the signs currently point not to a collision with a piece of space junk or other external cause but rather to an issue aboard the spacecraft, which launched in 1995.
"Basically, the spacecraft was 20 years old and experienced what appears to be a catastrophic event associated with a power system failure," Andy Roake, chief of the Current Operations Division at Air Force Space Command Public Affairs in Colorado Springs, told Space.com.
Investigators think that failure by itself probably blew apart DMSP-F13 — which occupied a sun-synchronous polar orbit about 500 miles (800 kilometers) above Earth — generating the cloud of debris that the Air Force's Joint Space Operations Center (JSpOC) has detected near the satellite. (To date, 43 pieces of debris have been identified.)
Indeed, Air Force officials have said that the military weather satellite explosion was preceded by a sudden spike in the power system's temperature, "followed by an unrecoverable loss of attitude control." It was first reported by SpaceNews, a Space.com partner, on Feb. 27.
DMSP-F13 launched in March 1995 and last year surpassed 100,000 orbits around Earth. The satellite contributed key data to a number of U.S. military operations overseas.

Social networks on the Internet give a perfect possibility to see all kinds of human behavior simultaneously at one glance without the need for immediate interaction. You always have the time to read a comment, reflect on it, and give an answer – or not – appropriate to the discussion. You don’t have to answer right away, and exactly this gives you the opportunity to learn and to grow as a person.I think that when meeting people in person, we usually get overwhelmed just [...]
(TRFW News) With fall approaching, pumpkins are beginning to ripen up. Pumpkins hold a part in most people’s fall or Halloween traditions, whether it be through carving, baking or decorating.However, research shows that enjoying more of this amazing squash may also be helpful for those diagnosed with diabetes. There are currently over 20 million people in the U.S diagnosed with diabetes, representing related health care costs of as much as 132 billion dollars. (1) [...]
