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 […]

Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local Group of galaxies (which includes […]

An international team of astronomers led by a researcher at Keele University has solved a long-standing cosmic mystery surrounding one of the most extreme stars ever observed. The star, known as WOH G64, is located […]

Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has mapped a magnetic highway driving a powerful galactic wind into the nearby galaxy merger of Arp 220, revealing for the first time […]

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before its […]

A team of astronomers has employed a cutting-edge, artificial intelligence–assisted technique to uncover rare astronomical phenomena within archived data from NASA’s Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble […]

Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on […]

New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations published in Monthly Notices of the […]

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who’ve been involved in the project from its early days. In this Q&A, Josh Frieman, DES co-founder and associate […]

Some galaxies in the early universe were absolute powerhouses, churning out stars at rates that would dwarf the Milky Way’s modest stellar production. These “monster galaxies,” buried deep in dust between 10 and 12 billion […]
