This is the first image of Sagittarius A*, the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope project. European Southern Observatory/EHT Collaboration
Two galaxies, NGC 1512 and NGC 1510, appear to dance in this image from the Dark Energy Camera. The galaxies have been in the process of merging for 400 million years, which has ignited waves of star formation and warped both galaxies. NSF's NOIRLab/Dark Energy Survey
This illustration shows exocomets orbiting the nearby star Beta Pictoris. Astronomers have detected at least 30 exocomets in the system, which also hosts two exoplanets. Calcada
This artist's impression shows a two-star system, with a white dwarf (foreground) and a companion star (background), where a micronova explosion can occur. Although these stellar explosions are smaller than supernovae, they can be intensely powerful. Mark A. Garlick/European Southern Observatory
This sequence of images shows how the solid nucleus (or the "dirty snowball" heart) of Comet C/2014 UN271 was isolated from a vast shell of dust and gas to measure it. Scientists believe the nucleus could be 85 miles across. NASA/ESA/Man-To Hui (MUST)/David Jewitt (UCLA)
The Hubble Space Telescope has captured an image of the most distant star yet: Earendel, which is nearly 13 billion light-years away. NASA/ESA/Brian Welch (JHU)/Dan Coe (STScI)/Alyssa Pagan (STScI)
Astronomers have imaged a space phenomena called odd radio circles using the Australian SKA Pathfinder telescope. These space rings are so massive that they measure about a million light-years across -- 16 times bigger than our Milky Way galaxy. Jayanne English (U. Manitoba)
This illustration shows what happens when two large celestial bodies collide in space, creating a debris cloud. NASA's Spitzer Space Telescope saw a debris cloud block the light of the star HD 166191. NASA/JPL-Caltech
Some 4.4 million space objects billions of light-years away have been mapped by astronomers, including 1 million space objects that hadn't been spotted before. The observations were made by the sensitive Low Frequency Array telescope, known as LOFAR. Annalisa Bonafede
An unusual triangle shape formed by two galaxies crashing together in a cosmic tug-of-war has been captured in a new image taken by NASA's Hubble Space Telescope. The head-on collision between the two galaxies fueled a star-forming frenzy, creating "the oddball triangle of newly minted stars." J. Dalcanton/Space Telescope Science Institute/NASA
This image of the supernova remnant Cassiopeia A combines some of the first X-ray data collected by NASA's Imaging X-ray Polarimetry Explorer, shown in magenta, with high-energy X-ray data from NASA's Chandra X-Ray Observatory, in blue. NASA/CXC/SAO/IXPE
This image shows the Milky Way as viewed from Earth. The star icon shows the position of a mysterious repeating transient. The spinning space object beamed out radiation three times per hour and became the brightest source of radio waves viewable from Earth, acting like a celestial lighthouse. Dr Natasha Hurley-Walker/ICRAR/Curtin
This Hubble Space Telescope image shows the dwarf galaxy Henize 2-10, which is filled with young stars. The bright center, surrounded by pink clouds, indicates the location of its black hole and areas of star birth. NASA, ESA, Zachary Schutte (XGI), Amy Reines (XGI), Alyssa Pagan (STScI)
This image shows the Flame Nebula and its surroundings captured in radio waves. Th. Stanke/ESO
This artist's impression showcases a red supergiant star in the final year of its life emitting a tumultuous cloud of gas, experiencing significant internal changes before exploding in a supernova. The Astrophysical Journal/Northwestern University
