A zombie star feasting on its surrounding planets and asteroids hasn't escaped the cannibalistic process unscathed. Resulting debris has given this white dwarf a metal scar.

When NASA's asteroid-diverting DART mission slammed into the tiny moonlet Dimorphos, it didn't just shift its orbit — it also almost completely changed its shape, new research suggests.

February's Full Snow Moon may have been the smallest full moon of 2024, but it had a big impact on moon lovers, skywatchers, and astrophotographers across the globe who braved the cold to catch it.

Researchers have measured the gravitational pull exhibited by the smallest mass yet, a breakthrough that could lead to a quantum theory of gravity at last.

The sun has blasted out its most powerful flare of the current solar cycle. The X6.3 solar flare peaked in the afternoon on Thursday (Feb. 22) and is the most powerful flare since 2017.

The public is invited to contribute to NASA's Eclipse Soundscapes Project by recording sensory data as 2024's total eclipse passes overhead to determine its effect on the animal kingdom.

The neutron star stayed hidden for 37 years while lurking in the wreckage of a stellar explosion, Supernova 1987A.

Astronomers have discovered a radio signal from a 'JuMBO' in the Orion nebula, a weird celestial object discovered by the James Webb Space Telescope that defy star and planet formation models.

Intruding stars may have thrown Earth's orbit off-kilter in the past, causing shifts in our planet's climate, a new study suggests.

Scientists have brought the stars 'down to Earth' by creating 5 new isotopes that could reveal how heavy elements like gold are created when neutron stars smash together.

Using the James Webb Space Telescope, scientists have confirmed that neutron star mergers forge heavy elements like gold.

Astronomers have observed a so-called standard candle supernova generating clouds of cosmic dust, bringing us a step closer to understanding the life and death cycle of stars.

A new solution to Einstein's theory of general relativity suggests a hypothetical star could be made of stacked black holes.

A new camera on the South Pole Telescope has used the Cosmic Microwave Background as a celestial treasure map that could lead to the secrets of dark matter.

Ultimately, this could reveal how stars smaller than Jupiter are born.

Observations of galactic clusters made by the eROSITA X-ray all-sky survey could help solve a troubling tension in cosmology surrounding the 'lumpiness' of matter in the universe.

Astronomers have discovered a quasar that remained hidden for over the years is the brightest ever, powered by the fastest growing black hole ever discovered that eats a sun every day.

In Spring 2024, NASA will launch two tiny twin satellites as part of the PREFIRE mission that will journey to the poles to collect data that will help monitor climate change.

Grab a copy of Space.com's 2024 solar eclipse edition and a pair of solar eclipse glasses to get ready for April's exciting event.

The moon meets up with the Seven Sisters of the Pleiades on Friday (Feb. 16) as skywatchers get a chance to see lunar landmarks known as the Lunar X and Lunar V.

The highly magnetic neutron star underwent two massive shifts in velocity and then slowed down due to powerful magnetar winds.

Valentine's Day won't be all hearts and flowers for some "kissing stars." These "odd couples" were created by a close-quarters feeding dance.

Astronomers may finally know why some death shrouds created by the deaths of sun-like stars lack the element sulfur.

New research has shown that disease-causing bacteria carried in the human gut can also survive in Martian soil, a discovery with implications for future crewed exploration of Mars.

Astronomers have indirectly detected dark matter hanging from the "loose ends" of filaments that comprise the cosmic web in the Coma Cluster of galaxies.
