arXiv:2512.15858v1 Announce Type: new Abstract: Despite numerous search campaigns based on a diverse set of observational techniques, exomoons – prospective satellites of extrasolar planets – remain an elusive and hard-to-pin-down

The first results on the iconic active galactic nucleus MCG–6-30-15 captured with the XRISM mission show the most precise signatures yet of its supermassive black hole’s extreme gravity and the

A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine

Terrestrial planets such as Earth need an early solar system rich in short-lived radioisotopes. But the supernovae that create these elements would tend to rip an early system apart. A

A team of Canadian astronomers has used Webb’s observations of “Milky Way twins” in the early Universe to learn more about our galaxy’s turbulent youth.

Sunspots and solar flares go hand in hand. They generally occur in the same region of the Sun around the same time. We’ve long thought the same would be true

It sneaks up on us, every annual flip of the calendar into the new year. If skies are clear, keep an eye out for the brief but strong Quadrantid meteors

Size matters when it comes to telescopes. The bigger they are, the farther they can see. Prioritizing constructing large ones is therefore high on the priority list for many observational

The Atacama Millimeter/Submillimeter Array (ALMA), the world’s most powerful radio telescope, has received 145 new low-noise amplifiers (LNAs) that will increase its range and sensitivity.

For the first time, astronomers have caught a stellar nursery in the act of blowing giant celestial bubbles, revealing a massive outflow of gas stretching over 650 light-years from one
