Light from outside our galaxy is a couple of times brighter than scientists are able to explain

28. 12. 2022

Scientists were able to measure the cosmic optical background (COB) thanks to the data from New Horizons space probe at the edge of the Solar system. The light is significantly brighter than what light from known sources can explain. According to a new study led Teresa Symons it is two to three times brighter.

Most distant stars in the Milky way lie half-way to the Andromeda galaxy

Astronomers identified the most distant stars still belonging to our own galaxy. The variable RR Lyrae stars have a unique pulsating period related to its brightness which allows scientists to determine their distance. It was found to be 1,2 million light years away - almost half distance to our neighboring big galaxy - Andromeda.
