The supernova remnant Cassiopeia A, captured by NASA's James Webb Space Telescope in near-infrared light. The image shows the expanding material from the blast colliding with gas released by the star before the explosion.

James Webb Telescope Captures Image of Supernova That 'Absolutely Shattered' a Star

The new image gives astronomers a near-infrared look at the stellar explosion called Cassiopeia A, located around 11,000 light years away from Earth

RCW58, a Wolf-Rayet bubble nebula, is made of ejected material from the star WR 40, which shines at the center of the image.

The IceCube Neutrino Observatory first detected evidence of neutrinos originating from outside the Milky Way a decade ago.

Scientists Find Ghostly Neutrino Particles From the Milky Way

It's no surprise that neutrinos come from within our galaxy, but the tiny, chargeless particles are very hard to detect

A Finnish astrophotographer created the 1.7 gigapixel image by stitching together photos with a total exposure time of roughly 1,250 hours

This is the all-sky map created by the eROSITA X-ray telescope, represented in false color  (red for energies 0.3-0.6 keV, green for 0.6-1.0 keV, blue for 1.0-2.3 keV). The original image was smoothed in order to generate the above picture.

The Blue Ring Nebula is invisible to the human eye, but telescopes can measure the ultraviolet light, which is shown here in blue.

Astronomers Crack the Case of the Blue Ring Nebula

The source of the dazzling display puzzled scientists for more than a decade

Dust-rich outflows of evolved stars similar to the pictured Egg Nebula are plausible sources of the large presolar silicon carbide grains found in meteorites like Murchison.

Meteorite Grains Are the Oldest Known Solid Material on Earth

The oldest dust sample, perhaps 7 billion years old, predates the formation of our planet and the sun

Illustration of a hot Jupiter planet in the Messier 67 star cluster. Hot Jupiters are so named because of their close proximity — usually just a few million miles — to their star, which drives up temperatures and can puff out the planets.

What Astronomers Can Learn From Hot Jupiters, the Scorching Giant Planets of the Galaxy

Many of the planets that are roughly the size of Jupiter orbit right next to their stars, burning at thousands of degrees

The image reveals the black hole at the center of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the sun.
