University of Maryland School of Medicine researchers say they've established certain key features in proteins that are needed for life to function on Mars and other extreme environments.
Researchers say they've conducted the first reconnaissance of a distant planetary system, collecting the spectra of four red exoplanets which orbit a star 128 light years away from Earth.
NASA has created a 3D reconstruction of ancient water channels below the surface of Mars, revealing evidence of a catastrophic flood in the last 500 million years.
Scientists at the University of York say they've dispelled the so-called firewall paradox which suggests that anything falling into a black hole would be burned up as it crossed the event horizon.
Using binary stars as a standard for reference, astronomers have measured the distance to our neighbouring galaxy, the Large Magellanic Cloud (LMC), more accurately than ever before.
The evidence is piling up that the building blocks of life could have been brought to Earth by comets, after emerging in the dust of interplanetary space.
Astronomers have found the strongest evidence yet that the ocean on Jupiter's moon Europa may consist of salty water, like our own. And, they say, that salty water appears to be making its way to the surface.
As NASA's SpaceX Dragon spacecraft docks with the ISS, its head, Charles Bolden, has warned that recent political events could impact the agency's mission.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton, have together accurately measured, for the first time, the spin rate of a black hole with a mass two million times that of our sun.
