Astrophysicists with the Event Horizon Telescope (EHT) Collaboration have conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of distant galaxies at a frequency of around 345 GHz. When combined with existing images of supermassive black holes at the hearts of Messier 87
Astronomers using the Murchison Widefield Array in Western Australia have searched for alien signals at a 10 kHz spectral resolution originating from a population of about 2,800 galaxies toward the Vela supernova remnant. This illustration shows what the activities of a Kardashev Type III civilisation might look like – encapsulating the energy of stars by
In a paper published today in the Astronomical Journal, astronomers analyzed the evolution of massive galaxies at redshifts of 4-8 selected from the JWST Cosmic Evolution Early Release Survey (CEERS).

Physicists from the STAR Collaboration have observed the antimatter hypernucleus antihyperhydrogen-4 — composed of an antihyperon, an antiproton and two antineutrons — in collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) at DOE’s Brookhaven National Laboratory. An artistic representation of antihyperhydrogen-4 created in a collision of two gold nuclei. Image credit: Institute
Gliese 229B was the first known brown dwarf, discovered in 1995. In new research, astronomers observed Gliese 229 B with the GRAVITY interferometer and, separately, the CRIRES+ spectrograph at ESO’s Very Large Telescope. Both sets of observations independently resolved Gliese 229B into two components, Gliese 229 Ba and Bb. They orbit each other every 12.1 days with a semimajor axis of
Saudi Arabia has achieved a historic milestone by successfully testing the Middle East and North Africa's first hydrogen-powered train. Saudi Arabia has marked a historic milestone by successfully testing the Middle East and North Africa’s first hydrogen-powered train.
