Scientists have released a new study on the arXiv preprint server that catalogs the universe by mapping huge clusters of galaxies.This post was originally published on this site

A radio pulsar is like a cosmic lighthouse, a highly dense, rapidly rotating star that emits beams of radio waves. If Earth happens to be in the path, a “pulse” of radio waves will be […]

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are captured by neon and […]

Using ESA’s Gaia satellite, astronomers have detected 87 stellar streams associated with globular clusters (GCs) in our Milky Way galaxy. The discovery, which doubles the number of known GC stellar streams, was detailed in a […]

Astronomers using the James Webb Space Telescope (JWST) have captured the most detailed look yet at how galaxies formed just a few hundred million years after the Big Bang—and found they were far more chaotic […]

A powerful new telescope has captured its first glimpse of the cosmos, and could transform our understanding of how stars, galaxies and black holes evolve.This post was originally published on this site

The wavelengths of radio light are so large that you can’t capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you’d need a radio dish […]

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers from the University of California, Irvine (UCI) and elsewhere, have discovered two new exoplanets orbiting M-dwarf stars. The newfound alien worlds are similar in size to Jupiter […]

By combining the power of ground-based and space-based telescopes, astronomers have discovered a new brown dwarf—a type of object that lies between a star and a planet—orbiting a small star about 55 light-years from Earth. […]

Astrophysicists from Keele University, alongside an international research team supported by NASA, detected large complex organic molecules in ices outside the Milky Way for the first time—offering a glimpse into the chemistry of the early […]
