In 2024, astronomers surmised that Betelgeuse might have a stellar “buddy.” If this hypothetical companion existed, it would help answer some questions about the red supergiant’s strange glowing patterns. As it turns out, these suspicions were correct. After numerous false signals and empty search results, astronomers with NASA’s Ames Research Center have confirmed that Betelgeuse does, […]
An Interstellar Comet Is Here, and Its Age Is Mind-Bending
This article was updated at 9:00 a.m. ET on Friday, July 11, to include new information. After defending his PhD thesis on modeling interstellar objects on Monday, June 30, Matthew Hopkins intended to take some well-deserved time off. It would appear the universe had other plans for him. The very next day, the Atlas Terrestrial-impact […]
A Bold Mission to Hunt for Aliens on Venus Is Actually Happening
A UK-based mission is aiming to settle, once and for all, whether life exists on Venus. The mission plans to send a probe to the planet in search of microbial life, not on the surface, of course, but in the Venusian clouds. Over the past half-decade, scientists have detected the presence of phosphine and ammonia—two […]
Only the Third Ever Detected Interstellar Object May Be Whizzing Through Our Solar System Right Now
Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system. Preliminary observations suggest it came from interstellar space, and if confirmed, it would mark the third discovery of an interstellar object in history. The cosmic visitor—tentatively named A11pl3Z—first appeared in data collected by the Asteroid Terrestrial-impact Last Alert […]
A Game-Changing Telescope Is About to Reveal Its First Images. Here’s How to Watch
A state-of-the-art telescope nearly 25 years in the making will finally reveal its first images on Monday, June 23, and you can watch the event in realtime. The Vera C. Rubin Observatory, perched atop a mountain in the Chilean Andes, boasts the largest digital camera ever built for astronomy. The telescope, overseen by the National […]
These Two Galaxy Clusters Are About to Smash Into Each Other—Again
Roughly 2.8 billion light-years from Earth, two galaxy clusters are engaged in a cosmic tussle. These enormous structures last collided about a billion years ago, but now, it appears they’re going back for round two. The galaxy clusters involved in this scuffle are part of a larger system—a “combined” galaxy cluster—called PSZ2 G181. In a […]
Researchers Claim Ancient Chinese Star Catalog Is the Oldest of Its Kind—But Not Everyone’s Convinced
Humans have been stargazing for thousands—possibly hundreds of thousands of years. Ancient people around the globe looked to the heavens for physical and spiritual guidance. Dozens and dozens of generations later, their descendants are now arguing over which civilization created the oldest known visual star catalog in the world. Researchers from the Chinese Academy of […]
New Minor Planet Spotted Past Pluto, One of the Largest Distant Objects in the Solar System
There’s a new frozen oddball orbiting the Sun, and it’s not your average space rock. It’s a planet—a minor one, to be fair—but one of the largest yet discovered and with an orbit around the Sun that puts our own planet’s orbit to shame. The minor world is dubbed 2017 OF201; the International Astronomical Union’s […]
Rare Exoplanet Orbits Two Stars at a Wild 90-Degree Angle
In 2018, astronomers discovered a pair of brown dwarf stars orbiting each other in a rare system known as an eclipsing binary. Further observations show that the binary, named 2M1510, is even more unique than previously believed. Researchers are reporting the discovery of an exoplanet, named 2M1510 (AB) b, orbiting its host star at an […]
The Star Set to Explode Totally Flaked. Here’s What to Expect Next
Sky watchers were disappointed last night when a binary star system didn’t erupt in a nova explosion that was predicted to take place on Thursday. But fear not, the famous blaze star is still due for its recurring nova to erupt any day now. The binary star system T Coronae Borealis (T CrB), also known […]
