Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), have […]

The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that […]

Astronomers at The University of Manchester have played a leading role in the discovery of a new cosmic object that is much larger than anything astronomers have seen before in the distant universe. This new […]

An international team including Cornell researcher Jake Turner has developed a novel analysis method capable of uncovering previously undetectable stellar and exoplanetary signals hidden within archival radio-astronomical data. Thanks to this innovation, scientists have discovered […]

A team of researchers studying the uncertainties associated with a phenomenon known as cosmic birefringence has developed a method to reduce uncertainties in its observational measurements, according to a new study published in Physical Review […]

In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last Milky Way core-collapse supernova seen by humans was about 1,000 years ago. That means we’ve […]

When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they’re dormant. They’re actively accreting only a tiny amount of matter and emit only faint, […]

Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 (M87) in the constellation Virgo is visible over distances of 3,000 light-years and can be observed over […]

An international team of astronomers has analyzed the data from long-term multiwavelength monitoring of a distant blazar known as OP 313. Results of the new study, published January 18 on the arXiv preprint server, shed […]

Using various space telescopes and ground-based facilities, astronomers have performed X-ray and radio observations of an accreting millisecond X-ray pulsar known as MAXI J1957+032. Results of the observational campaign, published on the arXiv preprint server […]
