Using the Gemini-South telescope and a speckle imaging camera, a team of astronomers have obtained the highest-resolution images available of TRAPPIST-1. When it comes…
In a newly published study, a team of astronomers call attention to a neglected riddle of the expansion of the universe: although cosmic acceleration might…
Astronomers may have detected the slowest spinning neutron star to date. The object is in the middle of the RCW 103 supernova remnant, which is…
New research shows that a recently discovered mysterious X-ray signal most likely originates from sulfur ions, not from dark matter. A mysterious X-ray signal from…
Using Chandra and several other telescopes, astronomers have found the most distant galaxy cluster to date. This cluster, called CL J1001+0220, lies about 11.1 billion…
New research suggests that IRAS 19312+1950 might be a protostar a star still in the making. For years, astronomers have puzzled over a massive star…
New research from the Harvard-Smithsonian Center for Astrophysics shows that the center of the Milky Way was once a very active place. The center of…
Using data from NASA’s Juno probe, astronomers hope to gain a better understanding of Jupiter and the many Jupiter-like planets in our galaxy. Our galaxy…
An international team of astronomers has discovered a massive galaxy that consists almost entirely of dark matter. The galaxy, Dragonfly 44, is located in the…
Scientists reveal that a newly discovered, roughly Earth-sized planet orbiting our nearest neighboring star might be habitable. Astronomers using ESO telescopes and other facilities have…
Using data from NASA’s Wide-field Infrared Survey Explorer (WISE) and Fermi Gamma-ray Space Telescope, astronomers studying distant galaxies powered by monster black holes have uncovered…
New research from the Harvard-Smithsonian Center for Astrophysics reveals that the Venus-like Exoplanet GJ 1132b might possess a thin, oxygen atmosphere – but no life…
New Chandra data of the supernova remnant G11.2-0.3 raise new questions about the timing of its origin. Chandra observations show that dense gas clouds lie…
Using data from NASA’s Stratospheric Observatory for Infrared Astronomy and other observatories, astronomers reveal how a particular type of organic molecules, the raw materials for…
A team of astronomers has discovered two dwarf galaxies that have traveled from the remote hinterlands of space to the Milky Way. NASA’s Hubble Space…
Using the ALMA submillimeter array, astronomers image the disk around HR8799 with a spatial scale as small as only thirty-two au, enough to probe the…
A team of astronomers from the Harvard-Smithsonian Center for Astrophysics has detected chiral molecules in interstellar space. Life on Earth is based on chiral molecules….
