Professor: What really happened out of Apollo 11? Buzz Aldrin: An amazing thing, even though we have always known of this possibility. The fact is that they (aliens) have ordered us to...
Gravity ripples scattering off warped spacetime near massive objects might help astronomers peer inside stars and find globs of dark matter.
Listen • 3:55 An artistic image of what happens when a monstrous black hole collides with — and gulps down — a neutron star the size of a large city. A black hole swallowing a neutron star — a star more massive than our sun but only about the size of a city — has been observed for the first time ever. Each of these space monsters is among the most extreme and mysterious phenomena in the universe. The new find, described Tuesday in The Astrophysical Journal Letters, shows how the very fabric of the universe gets roiled when the two come together. Researchers foun...
30. Juni 2021 Bei der Kollision von einem Neutronensterns mit einem Schwarzen Loch werden Gravitationswellen frei – diese haben Astronomen jetzt erstmals eindeutig nachgewiesen. © Carl Knox, OzGrav/ Swinburne University Kosmischer Pac-Man: Astronomen haben die ersten eindeutigen Gravitationswellen-Signale von der Kollision eines Neutronensterns mit einem Schwarzen Loch eingefangen. Die Observatorien LIGO und Virgo detektierten im Januar 2020 gleich zwei dieser Ereignisse. Das Schwarze Loch verschluckte den kleineren Neutronenstern dabei wahrscheinlich im Ganzen und ohne begleitenden Strahl...
endIndex: (CNN) — Nearly a billion years ago, two of the most extreme objects in the universe came together in a death spiral, and one of them didn't make it out alive. For the first time ever, astronomers have detected two separate instances of black holes swallowing dense neutron stars -- and it played out like Pac-Man in space. The gravitational waves caused by these two events reached Earth in January 2020, allowing astronomers to retrace the ripples in space-time back to when they occurred in distant galaxies 900 million light-years and a billion light-years away. The study, involving...
