Supernova
9 reportsWork involving Supernova is reported through event timescales, together with energy output and source populations. Claims involving energy output are weighed against instrument calibration and checked with population statistics; selection effects and uncertain source distances can alter inferred rates or energies.
Astronomers Link Two Supernova Remnants to a Single Binary Star System
A faint supernova remnant near the Jellyfish Nebula has been identified as the likely companion explosion from a binary star system, based on 16 years of gamma-ray data and multiwavelength observations
NASA Prepares Roman Space Telescope for 2026 Launch to L2 Orbit
NASA has fueled the Roman Space Telescope, a next-generation infrared observatory scheduled for launch in August 2026, aiming to collect hundreds of terabytes of cosmic data annually and expand studies of dark matter, dark energy, and exoplanets
Hubble Reveals High-Speed Gas Bullets from Rare Helium Nova in Milky Way
Astronomers using Hubble and other observatories have observed V445 Puppis, the Milky Way's only known helium nova, ejecting dense gas clumps at speeds up to 32 million kilometers per hour
Sun's Silver Shortfall Explained by Advanced Atomic Modeling
Researchers using high-fidelity atomic simulations have found that the sun contains significantly more silver than previous spectral measurements suggested, resolving a longstanding discrepancy between solar and meteorite compositions
Webb Telescope Links 'Little Red Dots' to Ancient Star Clusters
Astronomers using the James Webb Space Telescope have traced mysterious 'Little Red Dots' in the early universe to the possible origins of globular clusters, offering new clues about how these dense stellar systems formed
Webb Telescope Reveals How Early Galaxies Produced Cosmic Dust
Astronomers used the James Webb Space Telescope to study a nearby dwarf galaxy, uncovering how ancient galaxies enriched the early universe with stardust essential for star and galaxy formation
Possible Twin Supernova Remnants Identified in the Jellyfish Nebula
Astronomers analyzing data from NASA's Fermi Gamma-ray Space Telescope and other observatories have found evidence suggesting both stars in a binary system exploded as supernovae, leaving overlapping remnants in the IC 443 region
Webb data links early red dots to UV-bright companions and black hole seeds
A new analysis of James Webb Space Telescope images suggests that compact 'little red dots' in the early universe may form near ultraviolet-bright companions, offering a possible route to the rapid birth of supermassive black holes
NASA's IXPE Maps Magnetic Field of Unusual Pulsar in Milky Way
Astronomers have used NASA's Imaging X-ray Polarimetry Explorer to directly map the magnetic field around the pulsar PSR J1101-6101, revealing how high-energy particles stream through the Milky Way and testing long-standing theoretical predictions
