Markarian 315
A double Nucleus in an active galaxy
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...
SN 2026gzf
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...

Rubin image of SN 2026gzf host galaxy pre-explosion (May 2025–January 2026)
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...
DECam image of supernova SN 2026gzf (25 March 2026)
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...
DECam image of supernova SN 2026gzf host galaxy pre-explosion (9 March 2016)
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...
DECam image of supernova SN 2026gzf (3 April 2026)
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...

Betelgeuse B
VLT image of Betelgeuse’s companion
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...
NGC 4654
One-sided spiral
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...
