'Planet Y' theory hints at hidden Earth-size world lurking in the solar system — and it could be much closer to us than 'Planet Nine'
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."
Hidden 'doomed' star revealed by James Webb Space Telescope could solve decades-old mystery
Researchers have identified a massive red supergiant on the brink of supernova in images from the James Webb Space Telescope, shedding light on a decades-old star mystery.
$100,000 quadrillion asteroid Psyche may be the product of metal volcanoes, study hints
The metal-coated asteroid Psyche may have had eruptions of molten iron and nickel on its surface. This situation was more likely if the space rock is made of the same chemicals as metal-rich meteorites, a new study suggests.
Hubble went supernova hunting — and found something unexpected: Space photo of the week
The Hubble Space Telescope reveals how color filters tease out the life cycles of stars in spiral galaxy NGC 6000 — while a surprise asteroid streaks through the frame.
Which planets are the youngest and oldest in our solar system?
There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?
Astronomers close in on comet 3I/ATLAS's origins, a strange gravity anomaly discovered off Africa and AI designs brand-new viruses

Comet 3I/ATLAS is losing water 'like a fire hose' on full blast
Researchers have discovered that interstellar comet 3I/ATLAS has been shedding water, providing insights into the building blocks of life outside of our solar system and the evolution of interstellar comets.
Groundbreaking image shows two black holes orbiting each other for first time
Observations by a system of radio telescopes have offered the first visual evidence for the existence of black hole pairs. But vital follow-up observations are needed before we know for sure.
James Webb telescope could have spotted controversial 'dark stars' in the far universe
Using observations from the James Webb Space Telescope, astrophysicists have spotted what they say is compelling evidence of a new type of cosmic object called a 'dark star.'
James Webb telescope finds 'remarkable' evidence that a black hole plowed through a galaxy, leaving an enormous scar behind
Using JWST and ALMA data, astronomers have spotted a superlong and narrow 'galactic contrail,' possibly produced by a black hole. The gas- and dust-rich tail is 20,000 light-years long but just 650 light-years wide.
