Artist’s impression. A planetary fragment orbits the star SDSS J122859.93+104032.9, leaving a tail of gas in its wake. Credit: University of Warwick/Mark Garlick A fragment…
Illustration of a Gamma-Ray Burst. NASA/D.Berry Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted…
Artist’s conception of the dusty, doughnut-shaped object surrounding the supermassive black hole, disk of material orbiting the black hole, and jets of material ejected by…
An IRAC/Spitzer Space Telescope infrared image of the center of our galaxy. The infrared penetrates much of the dust to reveal the stars of the…
A photo of the DF2 galaxy (Image credit: NASA, ESA, and P. van Dokkum [Yale University]) A Yale-led team of researchers is doubling down on…
A cosmic light show sparked by the formation of massive stars in the stellar nursery, called W51, glows over on a star field image (white)…
This image of Centaurus A, one of the closest active galaxies to Earth, combines the data from observations in multiple frequency ranges. Credit: ESO/WFI (optical),…
This still image is a single frame from an immersive, 360-degree, ultra-high-definition visualization that allows viewers to view the center of our Galaxy as if…
CTB 1, seen here in a deep exposure that highlights visible light from hydrogen gas, is the expanding wreckage of a massive star that exploded…
An artist’s impression of a quasar. A supermassive black hole sits at the center, and the gravitational energy of material accreting onto it is released…
In this illustration, several dust rings circle the Sun. These rings form when planets’ gravities tug dust grains into orbit around the Sun. Recently, scientists…
Binary star formation through disk fragmentation starts with a young star surrounded by a rotating disk of gas and dust. The disk fragments, with a…
This artist’s impression shows a computer generated model of the Milky Way and the accurate positions of the globular clusters used in this study surrounding…
Yale researchers have discovered a surprising link between the tilting of exoplanets and their orbit in space. The discovery may help explain a long-standing puzzle…
ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky…
Astronomers observed that the dark matter does not seem to clump very much in small galaxies, but their density peaks sharply in bigger systems such…
Images from IRIS show the tadpole-shaped jets containing pseudo-shocks streaking out from the Sun.Credits: Abhishek Srivastava IIT (BHU)/Joy Ng, NASA’s Goddard Space Flight Center Scientists…
Fig. 1. Night sky centered on the south Galactic pole in a so-called stereographic projection. In this special projection, the Milky Way curves around the…
Simulation of merging neutron stars calculated with supercomputers. Different colors show the mass density and the temperature some time after the merger has taken place…
