XTE J1118+480 is a low-mass X-ray binary in the constellation Ursa Major. It is a soft X-ray transient that most likely contains a black hole and is probably a microquasar.
APM 08279+5255 is a very distant, broad absorption line quasar located in the constellation Lynx. It is magnified and split into multiple images by the gravitational lensing effect of a foreground galaxy through which its light passes. It appears to be a giant elliptical galaxy with a supermassive black hole and associated accretion disk. It possesses large regions of hot dust and molecular gas, as well as regions with starburst activity.
Cygnus X-1 (abbreviated Cyg X-1)[11] is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole.
A new study reveals that a giant cloud of superheated gas, which is about 6 million degrees, is likely the result of a collision between a dwarf galaxy and a much larger galaxy called NGC 1232. Observations with NASA's Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree
In the image of the asteroid Eros made by the NEAR Shoemaker spacecraft on May 1, 2000, when it was at an orbital altitude of 53 km (33 miles), it is visible, a large rectangular object, 45 meters in diameter. Considering the fact that data from the spacecraft collected on Eros in December 1998...
PARIS - Scientists have discovered a primitive "supercluster" of galaxies forming in the early Universe, just 2.3 billion years after the Big Bang.
The structure, nicknamed Hyperion, is the largest and most massive to be found so early in the formation of the Universe, which sprang into existence around 13.7 billion years ago.
Its titanic mass is one million billion times that of the Sun.
