About fifteen years ago astronomers, using improved submillimeter wavelength telescopes, discovered a new class of very distant galaxies: submillimeter galaxies (SMGs). These objects are...

A star is typically born with a disk of gas and dust encircling it, the spinning remnant of the much larger cloud of natal material. As the star begins to shine, planets develop from the...

Correction: This press release claimed that the B-mode signal detected by BICEP2 offered direct evidence of gravitational waves from cosmic inflation (BICEP2 collaboration et al. 2014). S...

The bright X-ray source known as LMC X-3 resides in the Large Magellanic Cloud, the dwarf galaxy that is the Milky Way’s nearest neighbor. Two decades ago astronomers discovered that the...

When Warner Brothers animators wanted to include cutting-edge astronomy in a 1952 Bugs Bunny cartoon they set a scene at an observatory that looks like Palomar Observatory in California. ...

Nearly thirty years ago the Infrared Astronomy Satellite discovered that the universe contained many tremendously luminous galaxies, some more than a thousand times brighter than our own ...

X-rays of a specific wavelength emanating from the hearts of nearby galaxies and galaxy clusters could be signs of particles of dark matter decaying in space, two independent teams of ast...
