Interstellar comet is flying so fast that even Sun's gravity can't slow it down
The comet was identified as interstellar due to its highly eccentric hyperbolic orbit, which is unlike the elliptical orbits of native Solar System objects.
Astronomers find first visual proof of a star exploding twice
Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever.
Star Meets Stunning End by Exploding Twice
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 SNR 0509-67.5 with the European Southern Observatory’s Very Large Telescope, finding the first visual evidence of a star’s “double-detonation.”
Astronomers get picture of aftermath of a star's double detonation
The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its nuclear fuel and undergoes a core collapse,
A young giant planet orbits one star, while a planet-forming disk exists around same-aged companion star
A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation has finished,
Astronomers caught a star that blew up not once, but twice when it died
Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic evidence, captured using the European Southern Observatory’s Very Large Telescope in Chile, shows the first proof of a rare kind of stellar death called a double-detonation supernova.
Star Explodes Twice: Astronomers Capture Stunning Supernova Remains
New observations show a star that blew up in two separate bursts, confirming a long-suspected cosmic phenomenon called a double detonation.

Very massive stars vomit vast amounts of matter before collapsing into black holes
Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this transformation, they may vomit out more stellar material than we knew.
Massive ‘double detonation’ spotted by astronomers for the first time
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 layers indicate that the now-dead star exploded with a double-detonation.
