Black holes help with star birth

Research combining systematic observations with cosmological simulations has found that, surprisingly, black holes can help certain galaxies form new stars. On scales of galaxies, the role of supermassive black holes for ...

Hubble images a galaxy in dazzling detail

This image features the spiral galaxy NGC 691, imaged in fantastic detail using Hubble's Wide Field Camera 3 (WFC3). This galaxy is a member of the NGC 691 galaxy group named after it, which features a group of gravitationally ...

Image: Hubble views a not-so-lonely galaxy

Galaxies may seem lonely, floating alone in the vast, inky blackness of the sparsely populated cosmos—but looks can be deceiving. This image of NGC 1706, taken by the NASA/ESA Hubble Space Telescope, is a good example of ...

Astronomers discover giant relic of disrupted Tadpole galaxy

A team of astronomers from Israel, the U.S. and Russia have identified a disrupted galaxy resembling a giant tadpole, complete with an elliptical head and a long, straight tail, about 300 million light years away from Earth. ...

Making head or tail of a galactic landscape

Astronomers have used data from NASA's Chandra X-ray Observatory to capture a dramatic image of an enormous tail of hot gas stretching for more than a million light years behind a group of galaxies that is falling into the ...

The sombrero galaxy seen from cities

We're happy to share with you an update from our partner Unistellar. The team has recently collected a pair of images of the glorious Sombrero Galaxy (M104 in the Messier Catalog) taken during one of their  most recent ...

Hubble digs into cosmic archaeology

This NASA/ESA Hubble Space Telescope image is chock-full of galaxies. Each glowing speck is a different galaxy, except the bright flash in the middle of the image which is actually a star lying within our own galaxy that ...

New faint dwarf galaxy discovered

(Phys.org)—Astronomers have detected a new faint dwarf spheroidal galaxy using Japan's Subaru Telescope located in Hawaii. The newly found dwarf, designated d1005+68, belongs to a nearby galaxy group known as the M81 Group. ...

A peek into the merging galaxy cluster Abell 3888

(Phys.org)—Studying substructures of galaxy clusters can reveal important information about the morphology and evolution processes of these gravity-bound groups of galaxies. Optical spectroscopy is very helpful in this ...
