Scientists have been able to see the most detailed image so far of interstellar comet 3I/ATLAS thanks to the Hubble Space Telescope, in which a dust-filled coma surrounding the object and promising signs of a trail were unveiled. The comet was spotted on July 1, 2025, by the ATLAS survey and is going to town […]
Astronomers using a global radio telescope array have captured a record-sharp image of the blazar OJ 287, showing its particle jet is sharply bent. This twisted jet provides compelling evidence that OJ 287’s core contains not one but two supermassive black holes in a tight orbit. For decades, OJ 287’s ~12-year cycle of flares hinted

New observational evidence from the James Webb Space Telescope (JWST), which has yet to launch, may change that. JWST astronomers have found tantalising hints of an orbiting gas giant around Alpha Centauri A, the closest Sun-like star to us. Located just four light-years away in the Alpha Centauri triple-star system, the potential planet sits within

Astronomers have discovered the most distant black hole yet, an ancient quasar more than 13 billion light years from our own Earth, incredibly close to the limit of where scientists even expect supermassive black holes to form. The cosmic behemoth of a galaxy, known as CAPERS-LRD-z9, provides a wide-window echo back in time to one

The concept of a large, hidden planet or planets lurking in the most distant regions of our solar system has been known since before Pluto’s discovery on 1930s. Originally named “Planet X,” it had been proposed to account for irregularities in Uranus’s orbit. That mystery was eventually resolved by recalculating Neptune’s mass. But in 2016,

Astronomers have found a vast, never-before-noticed reservoir of stellar material, hundreds of light-years across, lurking in a cold, dark, starless swath of our galaxy. It’s dubbed the Midpoint Cloud and was identified using the Green Bank Telescope; it appears to channel dense clouds of material into the heart of our galaxy. It harbours active regions
