In April 2019, the Event Horizon Telescope (EHT) collaboration made history when it released the first-ever image of a black hole. The image captured the glow of the accretion disk surrounding the supermassive black hole (SMBH) at the center of the M87 galaxy, located 54 million light-years away. Because of its appearance, the disk that encircles this SMBH beyond its event horizon (composed of gas, dust, and photons) was likened to a “ring of fire.” Since then, the EHT has been

Almost every large galaxy has a supermassive black hole churning away at its core. In most cases, these black holes spin in concert with their galaxy, like the central hub of a cosmic wagon wheel. But on December 18, 2024, NASA researchers announced they had discovered a galaxy whose black hole appears to have been turned on its side, spinning out of alignment with its host galaxy.The galaxy, NGC 5084, was discovered centuries ago by German astronomer William Herschel, but it took new techniques

Webb onthult de fonkelende pracht van Westerlund 1

22-12-2024 10:03 via scientias.nl

De James Webb-ruimtetelescoop heeft een verbluffende nieuwe opname vrijgegeven van Westerlund 1, de grootste en meest massieve open cluster in onze Melkweg. Deze sterrenhoop, gelegen op ongeveer 12.000 lichtjaar afstand, herbergt honderden gigantische sterren, waarvan sommigen miljoenen keren helderder zijn dan onze zon. Dankzij Webb’s infraroodogen zien we deze cluster in ongekend detail, van de […]

Through the Artemis Program, NASA will send the first astronauts to the Moon since the Apollo Era before 2030. They will be joined by multiple space agencies, like the ESA and China, who plan to send astronauts (and “taikonauts”) there for the first time. Beyond this, all plan to build permanent habitats in the South Pole-Aitken Basin and the necessary infrastructure that will lead to a permanent human presence. This presents many challenges, the most notable being those arising from

Where’s the Most Promising Place to Find Martian Life?

22-12-2024 01:32 via universetoday.com

New research suggests that our best hopes for finding existing life on Mars isn’t on the surface, but buried deep within the crust.Several years ago NASA’s Curiosity rover measured traces of methane in the Martian atmosphere at levels several times the background. But a few months later, the methane disappeared, only for it to reappear again later in the year. This discovery opened up the intriguing possibility of life still clinging to existence on Mars, as that could explain the se
