A new study conducted by a group of astrophysicists led by Dr K. Dasyra suggests that black hole jets can affect the star formation in galaxies by both dispersing and heating large amounts...
A deep optical image of the gas-rich galaxy GASS 3505 which in at radio wavelengths shows a ring of neutral hydrogen gas, probably a result of accretion (there is a faint streamer seen to the left in this image)....

Astronomers may have solved the mystery of the peculiar volatile behavior of a supermassive black hole at the center of a galaxy. Combined data from NASA's Chandra X-ray Observatory and...
These three planetary discs have been observed with the SPHERE instrument, mounted on ESO's Very Large Telescope. The observations were made in order to shed light on the enigmatic evolution of fledgling planetary systems.The central parts of the images...
