Stars and Galaxies

Distant galaxies that existed a few hundred million years after the Big Bang are brighter than expected in JWST images because they were experiencing bursts of intense star formation.

Two new infrared mosaics of the Orion Nebula showcase the JWST's abilities while revealing new insights into this familiar star-forming region.

The shell galaxy NGC 3923's symmetrical onion-like layers, that extend 150,000 light-years across space, appear in a new photo from the Dark Energy Camera.

Two decades of Hubble Space Telescope data reveal the stunning threads of a dead star's leftovers.

For the first time, astronomers have directly imaged the faint glow of the diffuse cosmic web that stretches throughout the known the universe.

The James Webb Space Telescope has snapped a stunning image of a perfectly formed Einstein ring, which is also the most distant gravitationally lensed object ever detected.

A supernova that recently exploded in the Pinwheel Galaxy has revealed hitherto unknown information about the final days of the star that exploded.

The radio signals hint at an important evolutionary step in the lives of galaxies.

Over two decades of data from NASA’s Chandra X-ray Observatory helped scientists craft a stunning new video of a historic stellar eruption.

Galaxies sported disks and spiral arms as early as 3.7 billion years ago, according to new data from the James Webb Space Telescope.

The James Webb Space Telescope has observed galaxies defying the "cosmic rulebook" in the early universe, to the surprise of astronomers who hope to learn more about the evolution of the universe.

In the extreme hearts of neutron stars, fundamental particles are twisted into strange 'pasta' shapes that could reveal untold secrets about how dead stars evolve.

An invisible halo of misaligned dark matter could explain the warps at the Milky Way's edges.

A faint "bridge" of gas connects two colliding galaxies in a new photo from the Hubble Space Telescope.

Supermassive black holes are even more fearsome eaters than scientists suspected, thanks to a "delivery system" that could help them feed over months rather than hundreds of years.

A new high-resolution, wide-field telescope situated in China offers its first stunning view.

A study of the Squid Galaxy, Messier 77, has revealed how chemicals swirl around its central black hole, revealing supermassive black holes impact the chemical evolution of their galaxies.

NASA has highlighted a new set of vibrant cosmic images, each one painted by the observatories that help us see what our eyes cannot.
