Alert F-16s out of California scrambled to hunt down mysterious targets over Nevada and California twice on Sunday.

A distant star dimmed by 97% for nearly 200 days. Astronomers say giant rings around a brown dwarf or super-Jupiter may explain it.

In other instances, cyclists may find themselves pedaling hard to progress down an obvious slope, as if gravity is pushing them in the opposite direction. The rest of this article is behind a paywall.

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver ...

INSIDE THIS REPORT The discovery did not arrive with spectacle. It arrived in spectral lines—quiet, technical, and unmistakable. NASA’s SPHEREx telescope has now detected organic molecules streaming ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a ...

Scientists created a large open database that uses light patterns to help satellites detect plastic in oceans more accurately from space.

One of those tools is 3D scanning. Using portable scanners, it is now possible to capture the full surface geometry of an object with high precision, without touching or damaging it. Every curve, ...

Republicans sought short-term DHS funding to continue talks, but Sen. Chris Murphy objected on behalf of the Democrats. A shutdown is likely.
