Let’s first talk about how mysterious dark energy is. Einstein, back in the day, added a cosmological constant to his equations to make the universe "static," but later regretted it, calling it the ...

Images taken with the MIRI infrared camera on the James Webb Space Telescope (JWST) have made it possible to observe the first galaxies in long-wavelength infrared light for the first time. Alongside ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA's powerful James Webb Space Telescope (JWST ...

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly ...

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best ...

The James Webb Space Telescope observed the same region of sky captured in the famous Hubble Ultra Deep Field image, revealing thousands of distant ancient galaxies. - ESA / NASA / CSA / G. Östlin / P ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology. New observations of a pair of ...

See amazing views of the M74, NGC 7496, IC 5332, NGC 1365, and NGC 1433 galaxies captured using the James Webb Space Telescope.The Physics at High Angular resolution in Nearby Galaxies (PHANGS) ...

James Webb Space Telescope (JWST) has found a dozen dormant (or affectionately called “sleeping beauty”) galaxies, which are ancient galaxies that have mysteriously stopped forming stars. The surprise ...

Something unusual may have risen from the ashes of an epic smashup. In the middle of a galaxy shaped like an infinity symbol — thought to be the result of two galaxies colliding — sits a supermassive ...
