Researchers have found a suspected clump of dark matter lurking within the luminous halo of a well-known "Einstein ring." The mysterious object, the smallest of its kind ever seen, could help shed light on the universe's missing matter.

Astronomers have discovered a surprisingly "pristine" red giant with the lowest concentration of heavy elements ever seen in a star. It is likely a direct descendant of one of the universe's first stars.

A new study has revealed that our understanding of the South Pole-Aitken basin was quite literally back-to-front, meaning astronauts on NASA's future Artemis III mission may be able to collect valuable samples of ancient radioactive material, known as KREEP.

A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for almost a decade. However, the evidence for this newly theorized world is "not definitive."

Comet Lemmon, discovered earlier this year, will make a close approach to Earth later this month, giving skywatchers the chance to see its surprising lime-green glow.

New observations suggest that the dwarf planet Makemake is surrounded by faintly glowing methane gas. Scientists are unsure if the gas is contained within a wispy atmosphere or being ejected into space.

A new report from the Commercial Space Federation warns that China could soon overtake the U.S. in the "new space race." The country's rapid progression starkly contrasts the limitations imposed on NASA by record-breaking budget cuts.

A new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't completely understand" why.

The "potentially hazardous" asteroid 2025 FA22 will fly close past Earth at more than 24,000 mph on Thursday (Sept. 18). The space rock was previously predicted to have a slim chance of impacting our planet in 2089, temporarily earning it the top spot on a major risk list.

A new analysis of asteroid Ryugu hints that the "potentially hazardous" space rock once had flowing water in its core, possibly leftover from the impact that created it.

New photos captured during the recent "blood moon" total lunar eclipse show that the interstellar comet 3I/ATLAS may be turning green as it gets closer to the sun.

NASA's Perseverance rover has photographed a peculiar rock formation that looks eerily like a turtle poking its head out from its protective shell.

A giant S-shape structure, around 10 times wider than Earth, recently appeared in the center of the sun, moments before our home star unleashed an even larger plume of plasma that later crashed into our planet.
