Astronomers have an intriguing idea for searching for dark matter, measuring the effect of particle self-annihilation inside various astronomical objects, from planets to stars and even white dwarfs. Now, astronomers are suggesting that dark matter annihilation should have a noticeable effect on the temperature of neutron stars. Dark matter could be collecting inside the intense gravity wells of neutron stars, annihilating and making them hotter than they should be.

Astronomers think they've detected the first-ever rainbow-like "glory effect" on an exoplanet. The observations were made with ESA's Cheops mission, which helps to pin down the characteristics of known exoplanets, including the ultra-hot Jupiter WASP-76b. When the star's light passes through a planet's atmosphere, it creates colorful concentric rings that have been seen on Earth and even Venus but never on an exoplanet.
