Study suggests much more water on the moon than thought

A trio of researchers at the University of California has found evidence that suggests there is far more ice on the surface of the moon than has been thought. In their paper published in the journal Nature Geoscience, Lior ...

ExoMars radio science instrument readied for Red Planet

An ambitious instrument for ESA's ExoMars 2020 mission has passed its testing in conditions resembling those on the Red Planet. It will now be transported to Russia for its acceptance review, followed by integration onto ...

Modeling exoplanet atmospheres

All atoms and molecules emit distinctive spectral lines across the spectrum, the details of which depend on the internal structures of the species (for example, the vibration and rotation properties of molecules) and how ...

Chandra X-ray observatory celebrates its 20th anniversary

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra's powerful and unique X-ray eyes have contributed ...

Space-enabled app for pilots takes to the skies

An app that integrates navigational data and weather conditions to improve flight safety for pilots has been launched. Its inventors hope to have a full commercial version on sale by the end of the year.

Astronomers decode Milky Way's violent birth

The Milky Way gobbled up a galaxy one quarter of its mass 10 billion years ago in a "violent collision" that didn't fully settle for eons, astronomers said in new research published Monday.

Astronomers map vast void in our cosmic neighborhood

An astronomer from the University of Hawaiʻi Institute for Astronomy (IfA) and an international team published a new study that reveals more of the vast cosmic structure surrounding our Milky Way galaxy.
