Around 1,645 light-years from Earth sits a binary star system, containing a white dwarf and a red dwarf on such a close orbit that each revolution smacks their magnetic fields together, producing a burst of radio waves.
In April of 2024, astronomers spotted an unusual event that astronomers named EP240408a. While the explosion was originally thought to be a gamma-ray burst, it now appears it might represent a new class of powerful cosmic explosion.
Fast radio bursts (FRBs) are puzzling phenomena because their details are so difficult to resolve. Astronomers added another piece to the puzzle with the detection of an FRB that seems to originate in a dead galaxy.
Astronomers at the University of Sydney have found the slowest rotating pulsar yet found, a 'cosmic lighthouse' that spins once every 6.5 hours, pushing the boundaries of what was thought possible.
The James Webb Space Telescope is celebrating three years from its launch. Its discoveries have already changed our understanding of the early universe.
A few years ago, a radio telescope operating out of the desert of Western Australia observed something very weird.
The signal, recorded in 1977, was at first suspected to be an alien transmission. Now scientists suggest the 47-year-old radio signal was the result of a rare event that caused a massive cloud of hydrogen to shine super brightly.
One group of scientists thinks that we may already have detected technosignatures from a technological civilization's Dyson spheres, but the detection is hidden in our vast troves of astronomical data.
An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
NASA astronomers have discovered an unexpected "signal" coming from outside our galaxy, which they can't explain.
Astronomers using NASA's Hubble Space Telescope have found a rare fast radio burst (FRB). This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date.
A strange star in the Milky Way bares the signature of a unique explosion of a giant star that once existed billions of years ago in the era of the cosmic dawn.
The latest discovery of an ultra-large structure called the "Big Ring" adds to "mounting evidence" that challenges what we know about the universe.
A new study published in the Monthly Notices of the Royal Astronomical Society has now shed new light on them, after spotting a “highly active” repeating FRB signal that is behaving differently to anything ever detected before.
Scientists in Utah have detected the second-most energetic cosmic ray ever seen. The powerful particle rivals the highest-energy cosmic ray on record, called the Oh-My-God particle, which was spotted in 1991.
