Large exomoons unlikely around Kepler-1625 b and Kepler-1708 b, astronomers say
Only two of the more than 5,300 known exoplanets have so far provided evidence of moons in orbit around them. In observations of the planets Kepler-1625b and Kepler-1708b from the Kepler and Hubble space telescopes, researchers discovered traces of s.....»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
New massive eccentric brown dwarf discovered
An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The f.....»»
