The rise and fall of Ziggy star formation and the rich dust from ancient stars

more »
Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can't explain this much dust in a galaxy this young, forcing us to rethink the history of star formation. Researchers now think MACS0416_Y1 experienced staggered star formation with two intense starburst periods 300 million and 600 million years after the Big Bang with a quiet phase in between.

NASA's Fermi Satellite clocks 'cannonball' pulsar speeding through space

more »
Astronomers have found a runaway pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes.

Water-bearing minerals on asteroid Bennu

more »
Astronomers have discovered evidence of abundant water-bearing minerals on the surface of the near-Earth asteroid (101955) Bennu. Using early spectral data from NASA's OSIRIS-REx spacecraft orbiting the asteroid, the team identified infrared properties similar to those in a type of meteorite called carbonaceous chondrites.

Hayabusa2 probes asteroid Ryugu for secrets

more »
The first data received from the Hayabusa2 spacecraft in orbit of asteroid Ryugu helps space scientists explore conditions in the early solar system. The space probe gathered vast amounts of images and other data which gives researchers clues about Ryugu's history, such as how it may have formed from a larger parent body. These details in turn allow researchers to better estimate quantities and types of materials essential for life that were present as Earth formed.

Carbon monoxide detectors could warn of extraterrestrial life

more »
Scientists have used computer models of chemistry in the biosphere and atmosphere to identify two intriguing scenarios in which carbon monoxide readily accumulates in the atmospheres of living planets. The models show that relatively high amounts of carbon monoxide are compatible with life and should not automatically rule out the possibility of life on some planets.

Superbugs have colonized the International Space Station -- but there's a silver lining

more »
Researchers have taken another small step towards deep space exploration, by testing a new silver- and ruthenium-based antimicrobial coating aboard the International Space Station (ISS). Their study shows that the AGXX® dramatically reduced the number of bacteria on contamination-prone surfaces -- and could help protect future astronauts beyond the moon and Mars.
