When the core of massive star collapses, it can form a black hole. Some of the surrounding matter escapes in the form of powerful jets that rush outward at almost the speed of light in opposite directions, as illustrated here. Normally jets from collapsing stars produce gamma rays for many […]

The ring galaxy NGC 474 at a distance of about 110 million light years. The ring structure was formed by merging processes of colliding galaxies. Credit: DES/DOE/Fermilab/NCSA & CTIO/NOIRLab/NSF/AURA Using data from the MUSE instrument, researchers at the Leibniz Institute for Astrophysics Potsdam (AIP) succeeded in detecting extremely faint planetary […]

A debris disk, which includes comets, asteroids, rocks of various sizes, and plenty of dust, orbits the star Beta Pictoris, which is blocked at the center of this 2012 image by a coronagraph aboard the Hubble Space Telescope. This is the visible-light view of the system. NASA’s James Webb Space […]

NASA’s Juno Mission observed pulsating electromagnetic ion cyclotron waves in Jupiter’s dawn magnetosphere that periodically expel energetic heavy ions into the atmosphere, producing stunning X-ray pulsations as captured by ESA XMM-Newton.

These images show the surface of the red supergiant star Betelgeuse during its unprecedented dimming, which happened in late 2019 and early 2020. The image on the far left, taken in January 2019, shows the star at its normal brightness, while the remaining images, from December 2019, January 2020, and […]

Artist’s impression of the Nu2 Lupi planetary system. Credit: © ESA Photobombs — when something or someone unexpectedly enters a camera’s field of sight during the taking of a photograph — happen every day. Sometimes it is a friend, other times a stranger or perhaps a bird. Rarely, however, is […]

Artist’s impression of exoplanet, showing tilted axis of rotation (adapted from NASA original image). Credit: NASA JPL Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research […]
