Life in these star-systems could have spotted Earth

Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems—within the small cosmic distance of 326 light-years—that could find Earth merely by watching our pale ...

Astronomers discover three new faint dwarf galaxies

By analyzing the data from the Dark Energy Survey (DES), an international team of astronomers has conducted a search for nearby faint dwarf galaxies. In result, they detected three such objects around the Sculptor Galaxy. ...

Earth-like biospheres on other planets may be rare

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis ...

First clear view of a boiling cauldron where stars are born

University of Maryland researchers created the first high-resolution image of an expanding bubble of hot plasma and ionized gas where stars are born. Previous low-resolution images did not clearly show the bubble or reveal ...

Europe seeks disabled astronauts, more women in space

The European Space Agency says it was "blown away" by the record number of applicants—more than 22,000—hoping to become the continent's next generation of space travelers, including more women than ever and some 200 people ...
