Using the largest catalog of exploding white dwarf vampire stars ever gathered has provided further evidence that dark energy ...

The spiral galaxy M83 is captured face-on, providing a clear view of its full structure. Chandra's X-ray data reveals ...

MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

Collapsing stars might act as cosmic laboratories for discovering hidden neutrino interactions. Neutrinos are among the most ...

Get Instant Summarized Text (Gist) A newly identified supernova remnant, G305.4–2.2 ("Teleios"), displays an unusually perfect circular symmetry, rare among known remnants.

In a universe governed by turbulence and chaos, perfection is rarely more than a mathematical ideal. Yet astronomers are puzzling over a newfound object that seems to defy that rule: a glowing, nearly ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in Nature Astronomy, researchers analyzed the centuries-old remains of supernova ...

The stellar corpse, a supernova remnant named 1E 0102.2-7219, met its demise in the Small Magellanic Cloud, a satellite galaxy of our Milky Way. NASA , ESA , STScI, ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

“Supernova remnants are our best cosmic laboratories for understanding how nature accelerates the highest-energy cosmic rays,” said Roger Blandford of Stanford University in Palo Alto, California.

In the case of Tycho’s supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1,000 — 1,000 times the speed of sound — is heating the remnant and ...
