The Dark Energy Camera has captured an image of the dazzling Coma Cluster, named after the hair of Queen Berenice II of Egypt. Not only significant in Greek mythology, this collection of galaxies was also fundamental to the ...
Scientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words, eventually, the two galaxies ...
The Webb Space Telescope has captured a pair of intertwined galaxies glowing in the infrared.
A duo of interacting galaxies commemorates the second science anniversary of NASA's James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations ...
The Large and Small Magellanic Clouds are well-known satellite galaxies of the Milky Way, but there are more. It is surrounded by at least 61 within 1.4 million light years (for context the Andromeda galaxy is 2.5 million ...
The onset of solar maximum has resulted in severe geomagnetic storms, with the possibility of aurora borealis events this weekend as far south as the northern United States. Do not be alarmed if you see awesome displays of ...
In images from NASA's retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams can help explain ...
This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group.
This image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, ...
This densely populated group of stars is the globular cluster NGC 1841, which is part of the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way galaxy that lies about 162,000 light-years away. Satellite galaxies ...
