Ultraluminous X-ray sources are objects that shine 10 million times brighter than the sun.

These objects break the Eddington limit, puzzling scientists.

A new study confirms the brightness of a ULX.

Solar storms cause bizarre events on Earth.

13 strange phenomena that happened on Earth were likely caused by solar eruptions.

Our sun is getting more active, and more solar storms are expected.

Ultraluminous X-ray sources should push matter away, but they don't.

The brightness of ULXs is caused by enormous amounts of material.

A pulsating neutron star caused M82 X-2, a ULX.

Superstrong magnetic fields may explain how ULXs can exist without breaking apart.

Ultraluminous X-ray sources shine 10 million times brighter than the sun, defying science as they break the Eddington limit. Mystery persists.

The James Webb Space Telescope discovered the first asteroid belt seen outside our solar system.
