Space-Earth System Produces Highest-Resolution Astronomical Image

Using an orbiting radio-astronomy satellite combined with 15 ground-based radio telescopes, astronomers have made the highest-resolution, or most-detailed, astronomical image yet, revealing new insights about a gorging black hole in a galaxy 900 million light-years from Earth.


New Theory Aids Search for Universe's Origin

New Theory Aids Search for Universe's Origin

In a new study, scientists from The University of Texas at Dallas and their colleagues suggest a novel way for probing the beginning of space and time, potentially revealing secrets about the conditions that gave rise to the universe.

New Theory of Secondary Inflation Expands Options for Avoiding an Excess of Dark Matter

Standard cosmology -- that is, the Big Bang Theory with its early period of exponential growth known as inflation -- is the prevailing scientific model for our universe


Signs of Second Largest Black Hole in the Milky Way

Signs of Second Largest Black Hole in the Milky Way

A team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, has found an enigmatic gas cloud, called CO-0.40-0.22, only 200 light years away from the center of the Milky Way.


The Most Powerful Supernova Ever Seen

The Most Powerful Supernova Ever Seen

Right now, astronomers are viewing a ball of hot gas billions of light years away that is radiating the energy of hundreds of billions of suns. At its heart is an object a little larger than 10 miles across.
