Webb telescope spots mysterious ‘Green Monster’ in supernova image

Operational only since July 2022, the James Webb Space telescope has already provided the world with astounding images of the universe. This includes new finds like “impossibly massive” galaxies and the most comprehensive profile of an exoplanet’s atmo… Continue reading Webb telescope spots mysterious ‘Green Monster’ in supernova image

Earth hit by brightest gamma-ray burst on record in 1-in-10,000-year event

NASA has confirmed that on October 9, 2022, our solar system was struck by a gamma-ray burst originating 1,900 light years away that was brighter than any since the beginning of human civilization, in what the space agency calls a “1 in 10,000 year” ev… Continue reading Earth hit by brightest gamma-ray burst on record in 1-in-10,000-year event

Long-lost invisible stellar graveyard revealed by radio telescope duo

Models of the universe predict that supernova remnants should be far more common than they are. Now, a new image from sensitive radio telescopes reveal that the missing remnants are hiding in plain sight.Continue ReadingCategory: Space, ScienceTags: Su… Continue reading Long-lost invisible stellar graveyard revealed by radio telescope duo

Trees tell tale of extreme, unexplained astronomical radiation storms

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

Hubble’s “magnum opus”: most precise measurement of universe’s expansion

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

Mysterious intergalactic ring may be a first-of-its-kind discovery

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 discover where a cosmic cataclysm blew a huge hole in space

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

New type of supernova detected as stellar corpse kills companion star

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….

Teardrop-shaped star is driving another to go supernova

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
