Today’s Picture of the Week, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), reveals one of the most detailed views yet of the surface of Betelgeuse — the famous orange star in the constellation of Orion, 600 light-years away. Unlike our own Sun, which is relatively smooth...
A NASA/ESA Hubble Space Telescope image of the core of the Seyfert galaxy Markarian 315 reveals two nuclei located approximately 6,000light-years apart. (Seyfert galaxies are a class of spiral galaxy with extremely bright nuclei that are thought to be powered by massive black holes accreting...
NSF–DOE Rubin image of the field around the progenitor to supernova SN 2026gzf
This image shows the field around the progenitor to supernova SN 2026gzf, detected by the Einstein Probe on 21 March 2026. The supernova progenitor appears as a bright blue dot within the galaxy located in the middle of the upper third at the center of this image. View a series of close-up...
This image shows the field around the progenitor to supernova SN 2026gzf, detected by the Einstein Probe on 21 March 2026. The supernova progenitor appears as a bright blue dot within the galaxy located at the center of this image. View a series of close-up images that show the evolving...
This image shows the host galaxy of the recently detected supernova SN 2026gzf. This supernova was first detected by the Einstein Probe on 21 March 2026. This image of the host galaxy, created by stacking multiple images taken between May 2025 and January 2026, reveals a bright blue source at...
This image shows supernova SN 2026gzf, which appears as a bright blue point source in the upper right corner of the host galaxy. SN 2026gzf was first detected by the Einstein Probe on 21 March 2026, and this image was taken just a few days later on 25 March 2026. This image was captured with...
This image shows the host galaxy of the recently detected supernova SN 2026gzf. This supernova was first detected by the Einstein Probe on 21 March 2026. This archival image of the host galaxy from 9 March 2016 reveals a bright blue source at the location of the supernova. Scientists say this...
This image shows supernova SN 2026gzf, which appears as a bright blue point source in the upper right corner of the host galaxy. SN 2026gzf was first detected by the Einstein Probe on 21 March 2026, and this image was taken a couple of weeks later on 3 April 2026. This image was captured with...
This image, taken with ESO’s Very Large Telescope (VLT), shows the clearest image ever of what likely is Betelgeuse B, a star orbiting Betelgeuse. The image was taken with the SPHERE instrument in December 2024, when the companion was predicted to be furthest apart from Betelgeuse as seen from...
The subject of this ESA/Hubble Picture of the Month is a spiral galaxy struggling against some of the titanic forces that appear on galactic scales in space. This is NGC 4654, an intermediate spiral galaxy in the constellation Virgo (the Maiden). “Intermediate” means that it lies between the...
What may first appear as a grainy glow is actually a dense field of millions of individually resolved stars. By distinguishing different generations of stars embedded throughout the dusty center, Webb gives astronomers new clues to the galaxy's history and the processes that continue to shape it.
This combined view of Centaurus A from NASA's James Webb Space Telescope pairs observations from the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). Webb's infrared vision exposes a warped disk of gas and dust left behind by a collision with another galaxy billions of years ago.
