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.

The faintest star system orbiting our Milky Way may be dominated by dark matter
By Keith Cooper published
The stars of a possible ultra-faint dwarf galaxy, known as UMa3/U1, could be held in place by the gravitational glue of dark matter.

'Shiva and Shakti': The ancient star streams that helped weave the Milky Way
By Robert Lea published
The Gaia space telescope has discovered two ancient stellar streams woven through the heart of the Milky Way, which were present 12 billion years ago.
