Astronomers refer to the Shapley Concentration as a "basin of attraction". It's a region containing many clusters and groups of galaxies and comprises the greatest concentration of matter in the local Universe.
TIC 290061484 is a system of gravitationally bound stars consisting of a tightly-orbiting binary pair with a third star that circles both. Astonishingly, they're so close together the entire system would fit inside the orbit of Mercury.
Ceres’ crust is probably made from 90% ice today. Using data from NASA’s Dawn mission, scientists found it was likely once a muddy ocean world.
Supermassive black holes are some of the most impressive objects in the universe - with masses around one billion times more than that of the Sun.
The light of a supernova that has traveled for 10 billion years to reach us has given us a new measurement of the Hubble constant - the accelerating rate at which the Universe is expanding.
Researchers analyzed new data describing the Moon's rigidity under the gravitational influence of Earth and the Sun, finding its mass is unlikely to be solid all the way through.
The science team thinks that igneous and/or metamorphic processes likely formed the rock.
Asteroid Ryugu possibly did not travel as far from its place of origin to its current near-Earth orbit as previously assumed. New research suggests that Ryugu was formed near Jupiter.
Using data from the Near-Infrared Spectrograph onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface of Pluto's moon Charon.
Using the European Southern Observatory's Very Large Telescope, astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our Sun.
Comet C/2023 A3 (Tsuchinshan-ATLAS) is expected to be the brightest spectacle of 2024.
New research finds that heart tissues aboard the space station beat about half as strong as on Earth.
If quantum communication exists, that could be a win for advanced technologies on our planet, but the process would make it impossible for us to detect it without some serious equipment upgrades.
A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportunity to study cosmology.
This means that astronauts may not be tied to visiting the lunar south pole on future missions to acquire water. Instead, they may be able to find water everywhere on the Moon.
