Scientists have discovered another rare triple quasar system.  Quasars are extremely bright and powerful sources of energy that sit in the center of a galaxy, surrounding a black hole. In…

The gravitational field surrounding the massive cluster of galaxies called Abell 68 acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies.…

Gas looks so pretty in space, don't you agree? This particular stellar gas is named planetary nebula ESO 456-67 . Do not get the wrong idea reading 'planetary'. This celestial object has nothing to…

Earth's radiation belts, called Van Allen belts, were discovered after the very first launches of satellites in 1958 by James Van Allen. Subsequent missions have observed parts of the belts but what…

Light from two massive stars that exploded hundreds of millions of years ago recently reached Earth, and each event was identified as a supernova. A supernova discovered Feb. 6th exploded about 450…

Astronomers using new data from the Nuclear Spectroscopic Telescope Array - NuSTAR - and the European Space Agency's XMM-Newton X-ray satellites have measured  the supermassive black hole at…

My favorite star, our very own Sun, has a multitude of spectacular features she shows off with grandeur. In fact, the Sun was the subject of my thesis and so she is extra special to me. When you…

 By analyzing data gathered by MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), a NASA probe that has orbited the planet since March 2011, researchers looking at X-ray…

Last month, physicists predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped both by the extreme gravity of black holes and by…

Unlike comets, asteroids don't have a trail - with some exceptions. Spanish researchers observed using the Gran Telescopio Canarias and discovered that something happened around July 1st, 2011 that…
