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.

James Webb telescope discovered its first exoplanet around star LHS 475

Astronomers led by Kevin Stevenson and Jacob Lustig-Yaeger report discovery of a new exoplanet around red dwarf star LHS 475. First sign of the exoplanet transit signal was found in data from the TESS space telescope. Astronomers then used James Webb to confirm its existence.

Discovery of two similar exoplanets in near resonance around star TOI 4342

Astronomers report discovery of two sub-neptune exoplanets orbiting red dwarf star TOI 4342 in near orbital resonance. Year on the inner planet lasts 5.5 days and on the outer planet almost twice as long. That means both bodies meet each other periodically once every year on the second planet.

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.
