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.

87 newly discovered galaxies might be some of the oldest in the universe

Astronomers identified 87 new distant galaxies in data from James Webb Space Telescope’s first year of observations. All of them have a red shift higher than 11 and up to 20 which indicates great distance and age.

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

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.
