Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed.

Lead author Dr. Matt Roth, from the ANU Research School of Astronomy and Astrophysics, said until now it has been unclear what created gamma-rays—one of the most energetic forms of light in the Universe—that appear in patches of seemingly “empty sky.”

The discovery could offer clues to help astronomers solve other mysteries of the Universe, such as what kind of particles make up Dark Matter—one of the holy grails of astrophysics.

“It’s a significant milestone to finally discover the origins of this ga...

A series of new images reveals that planets form in organic soups – and no two soups are alike. Astronomers have mapped out the chemicals inside of planetary nurseries in extraordinary detail. The newly unveiled maps reveal the locations of dozens of molecules within five protoplanetary disks – regions of dust and gas where planets form around young stars.

“These planet-forming disks are teeming with organic molecules, some which are implicated in the origins of life here on Earth,” explains Karin Öberg, an astronomer at the Center for Astrophysics | Harvard & Smithsonian (CfA) who led the map-making project...

Transporting a single brick to Mars can cost more than a million British pounds – making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.

In their study, published today in Materials Today Bio, a protein from human blood, combined with a compound from urine, sweat or tears, could glue together simulated moon or Mars soil to produce a material stronger than ordinary concrete, perfectly suited for construction work in extra-terrestrial environments.

The cost of transporting a single brick to Mars has been estimated at about US$2 mill...
