Dating to only a billion years after the big bang, JADES-ID1 may be the earliest, most distant galaxy protocluster astronomers have ever seen

New tools unlock new discoveries in science. So when a new type of non-destructive technology becomes widely available, it's inevitable that planetary scientists will get their hands on it to test it on some meteorites. A new paper, available in pre-print on arXiv, by Estrid Naver of the Technical University of Denmark and her co-authors, describes the use of two of those (relatively) new tools to one of the most famous meteorites in the world - NWA 7034 - also known as Black Beauty.

It turns out that continental breakups are just as messy as human ones, with the events leaving fragments scattered far from home

For those with retrograde cricopharyngeus dysfunction, daily life can be miserable, with symptoms such as bloating and chest pain. But a simple Botox injection can help

ESA’s Mars Express takes us on a journey across the southern highlands of Mars, including a flight around Flaugergues Crater.

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 led the most extensive observational study to date of runaway massive stars, which includes an analysis of the rotation and binarity of these stars in our galaxy.

When I say that the universe is 13.77 billion years old, it sounds rather authoritative.

Astronomers haven't found many gas giants orbiting white dwarfs. But is that because they're so difficult to spot? Or is it because their survival rate is so low? New research probes the issue.

The proposed installation — less than 10 miles from Paranal Observatory — sparked international concern. Now it’s canceled.
