Newly discovered comet C/2025 V1 (Borisov), which has some minor similarities to 3I/ATLAS, will make its closest approach to Earth on Tuesday (Nov. 11). However, despite recent rumors, the two objects are not related to one another.

Three Chinese taikonauts — Wang Jie, Chen Zhongrui and Chen Dong — will be extending their stay aboard China's Tiangong space station after their return capsule was struck by a presumed piece of orbital debris on Wednesday.

New photos show that the recently discovered comet C/2025 K1 (ATLAS) developed a surprising golden glow after reaching its closest point to the sun. Until now, the comet has gone under the radar, largely thanks to the more famous interstellar comet 3I/ATLAS.

Recent observations of the interstellar object 3I/ATLAS show that it has developed a faint blueish hue, hinting at a potential color change. This is the third time experts have seen the comet's coloring shift since it was discovered.

California-based startup Reflect Orbital aims to build a swarm of 4,000 giant mirrors in low Earth orbit to "sell sunlight" to customers at night. Experts warn that the mirrors could mess with telescopes, blind stargazers and impact the environment.

Researchers armed with a new "photonic lantern" device have discovered an unexpectedly asymmetrical disk of gas swirling around a mysterious star 162 light-years from Earth. The new technology could revolutionize ground-based astronomy, the researchers claim.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

Experts believe that a five-foot-wide piece of space debris discovered near an Australian mining town was part of a dead Chinese rocket. The wreckage likely crashed just before it was found.

Researchers discovered a hidden 185,000 light-year "bridge" of gas between two distant galaxies, which are also trailed by a 1.6 million light-year galactic tail — the largest of its kind ever seen.

An astrophotographer snapped a stunning shot of Comet Lemmon's flowing tail getting shredded by a strong gust of solar wind, just three days before it reaches its closest point to Earth.

A photographer snapped a striking shot of Comet Lemmon streaking over Scotland as the night sky unexpectedly filled up with a technicolor mix of vibrant auroras.

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."
