A team of astrophysicists using results based upon observations of 10 quasars say they have discovered the extent to which quasars and their black holes can influence their galaxies.  The…

A new study by astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered columns of cold, dense gas exiting the disk of nearby starburst galaxy NGC 253…

It would be great to study Mars "on location". You could do as much in a day or two, as our rovers could do in years. But there's a conundrum to face. Humans are host to hundreds of trillions of…

There are valley networks branching across the Martian surface, which makes it reasonable to believe that water once flowed on the Red Planet. Where water might have come from would be another…

On July 18th, 2013, at 9:06 a.m. EDT, the Solar and Heliospheric Observatory (SOHO) captured an image of a gigantic coronal hole hovering over the sun's north pole. Coronal holes are dark, low…

The orbital motion of two distinct populations of stars in an ancient globular star cluster, 47 Tucanae, have offered proof they formed at different times and it provides a rare look back into the…

The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the first ever image of the snow line in an infant solar system. Say what? On our planet, snow lines form at high altitudes where…

Why do we value gold? It's not strong, it's not pretty, it's rare but in the 21st century, given enough energy we can turn lead into gold, the way alchemists once only dreamed about. It's not just…

On July 16th, 2013, at 12:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection, sending billions of tons of particles into space. These particles cannot travel through the…

In 2011 the Very Large Telescope (VLT) discovered a gas cloud with several times the mass of the Earth accelerating towards the black hole at the center of the Milky Way.   The cloud is now so…
