Is dark matter's main rival theory dead? There's bad news from the Cassini spacecraft and other recent tests
By Indranil Banik, Harry Desmond published
One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up.

Milky Way's halo is filled with 'magnetic donuts' as wide as 100,000 light-years
By Robert Lea published
The discovery could help astronomers better understand how cosmic magnetic fields form and evolve.

Buried in the Cat's Paw Nebula lies one of the largest space molecules ever seen
By Robert Lea published
Scientists have discovered one of the largest molecules ever seen in space in the Cat's Paw nebula. The discovery hints at how chemical complexity emerges as stars form.

Cosmic fountain is polluting intergalactic space with 50 million suns' worth of material
By Robert Lea published
Astronomers have mapped a 20,000-light-year-long fountain of gas blasting from a nearby galaxy and polluting intergalactic space at 450 times the top speed of a jet fighter.
![In the field of one of JWST's largest-area surveys, COSMOS-Web, an Einstein ring was discovered around a compact, distant galaxy. It turns out to be the most distant gravitational lens ever discovered by a few billion light-years.](https://cdn.mos.cms.futurecdn.net/JCxsoVAh2S6BxpFnjccEif-320-80.jpg)
Exotic 'Einstein ring' suggests that mysterious dark matter interacts with itself
By Sharmila Kuthunur published
The unexplained mass of a remarkably massive galaxy suggests that dark matter interacts with itself, according to new observations by the James Webb Space Telescope.
