Tree rings are not just a great record of a tree’s life, but they can preserve a snapshot of the Earth and beyond at different times. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe… Continue reading Trees tell tale of extreme, unexplained astronomical radiation storms
NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.Continue Readi… Continue reading Hubble’s “magnum opus”: most precise measurement of universe’s expansion

Astronomers have discovered a strange intergalactic ring that may be the first of its kind found. The large radio circle lurks between the Milky Way and a neighboring galaxy, and its discoverers suggest it may be the remains of an unusual supernova.Con… Continue reading Mysterious intergalactic ring may be a first-of-its-kind discovery
Astronomers have discovered a big hole in space. New 3D visualizations of the Perseus and Taurus star-forming clouds have revealed a large cavity between them, possibly created in ancient supernova explosions.Continue ReadingCategory: Space, ScienceTag… Continue reading Astronomers discover where a cosmic cataclysm blew a huge hole in space
Astronomers have spotted a new type of supernova for the very first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky…. Continue reading New type of supernova detected as stellar corpse kills companion star
Supernovae usually appear suddenly in the sky, but now astronomers have spotted one in advance. The telltale sign is a star with a “teardrop” shape, as it gets stretched out by the gravitational pull of a companion.Continue ReadingCategory: Space, Scie… Continue reading Teardrop-shaped star is driving another to go supernova
A bizarre star may have its origins in one of the most energetic events in the cosmos. Astronomers have found that a star with a very unusual composition may have formed in the wake of a new type of hypernova – a stellar explosion with 10 times the ene… Continue reading Bizarre star may have been forged in a gigantic “hypernova”
Astronomers have detected the highest-energy light ever seen, streaming in from near the center of the Milky Way. Hundreds of gamma ray signals were detected with ultra-high energies, with the most powerful signals crossing the Peta-electronvolt (PeV) … Continue reading Gamma rays 10 times more energetic than thought possible detected
The supermassive black holes lurking at the center of most galaxies, including our own, are believed to have grown so big by gobbling up matter over billions of years. But a new study suggests they may have taken a shortcut, starting life as a hypothet… Continue reading Colossal primordial stars may have seeded supermassive black holes
