A color-enhanced image of millimeter-wave radio signals from the ALMA observatory in Chile shows a disk of gas and dust (right of center) around exoplanet…
Computer generated images showing a disk galaxy from a modified gravity simulation. Images show (right side of image, in red-blue color) the gas density within…
Artist’s concept of meteors impacting ancient Earth. Some scientists think such impacts may have delivered water and other molecules useful to emerging life on Earth.…
An artist’s impression of a Gamma Ray Burst jet over time, and the small patches of magnetic fields present, as revealed by new research. Credit…
Artist conception of gas streams (blue) feeding a galactic disk. The inflow fuels new star formation, and because the infalling gas is spinning, the size…
A galaxy with a quasar at its center, surrounded by dust. (Illustration: Michelle Vigeant) Astronomers have discovered a new class of “cold quasars” that could…
The team at the Cluster of Excellence Resolv has investigated chemistry in interstellar space. © RUB, Lehrstuhl für Astrophysik Solvated acids tend to release a…
The ultra-diffuse galaxy KKS2000]04 (NGC1052-DF2), towards the constellation of Cetus, considered previously a galaxy with no dark matter. Credit: Trujillo et al. A group of…
Artist’s impression of the aftermath of a merger between two supermassive black holes during a galaxy collision. Combining the observing power of two future ESA…
The colliding spiral galaxies in Arp 272 located in the constellation of Hercules. Astronomers have studied a suite of galaxy merger simulations to conclude that…
Gravitational waves, first detected in 2016, offer a new window on the universe, with the potential to tell us about everything from the time following…
