Researchers, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star…
Astronomers recently discovered that spots on the surface of supergiant star Zeta Puppis are driving huge spiral structures in its stellar wind. Massive stars are…
Using the Very Long Baseline Array, astronomers achieve record measurement for an improved picture of the Milky Way. Astronomers from the Max Planck Institute for…
Using a combination of multiwavelength observations, astronomers measure the characteristics of the Remarkable Jet in Quasar 4C+19.44. Quasars are galaxies with massive black holes at…
Astronomers reveal that spindle-like galaxies, which rotate along their longest axis, are much more common than previously thought. Galaxies are majestic, rotating wheels of stars?…
New Research reveals that giant exoplanets with long-period orbits are more likely to be found around young stars that have a disk of dust and…
Using the Swift Satellite Observatory, scientists reveal what was likely the most luminous white dwarf eruption ever seen. Astronomers have today announced that they have…
Using Atacama Large Millimeter/submillimeter Array (ALMA), astronomers spatially resolve the dust disk around the young protostar known as HH-212. Stars form as gravity contracts the…
Astronomers explain the reasons behind the behavior of Tabby’s Star. Some 1,500 light years from Earth, a mystery of stellar proportions is playing out. A…
Using NASA’s Spitzer and Swift missions, as well as the Belgian AstroLAB IRIS observatory, astronomers reveal new details on one of the most mysterious stellar…
NASA astronomers will use the James Webb Space Telescope to understand the creation of the universe’s first galaxies and stars. After it launches and is…
Different methods of studying cosmic expansion yield slightly different results, including for the age of the universe. In a new study, astronomers from the Harvard-Smithsonian…
NASA’s Hubble Space Telescope observed the farthest-discovered active inbound comet, Comet K2. Coming from the distant Oort Cloud, K2 is visiting our inner solar system…
Using radio and X-ray data, astronomers reveal that the mini-halo in the Perseus cluster seems to be influenced both by the AGN activity and the…
New research from the Harvard-Smithsonian Center for Astrophysics reveals that fast radio bursts should occur over the entire observable universe, with at least one FRB…
Using the Hubble Space Telescope, astronomers discovered two asteroids orbiting each other that have comet-like features in the asteroid belt. These include a bright halo…
New research from Yale University and the Satellites Around Galactic Analogs (SAGA) Survey reveals that the Milky Way might not be as “typical” as previously…
