A 'super-puff' planet like no other

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal ...

Researchers rewind the clock to calculate age and site of supernova blast

Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA's Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of ...

Building a giant 2-D map of the universe to prepare for the largest 3-D map

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3-D sky map yet, researchers first needed an even bigger 2-D map of the universe.
