(Image credit: NASA/Swift/Cruz deWilde) The James Webb Space Telescope has discovered the cause of the most powerful cosmic explosion since the Big Bang.The explosion (nicknamed the BOAT or "brightest of all time") is a gamma-ray burst (GRB) that spat photons at Earth with more energy than those
Daily Telescope: A Wolf-Rayet star puts on a howling light show
Hungry like the wolf — I'd like to see it go boom. Eric Berger - Feb 2, 2024 1:00 pm UTC Enlarge / The Crescent Nebula.1Zach1 Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll
Webb Telescope Unravels Cosmic Puzzle: Galaxy Mergers Illuminate Early Universe Mystery
The James Webb Space Telescope’s NIRCam has revealed small, faint galaxies merging with larger ones in the early Universe, solving the mystery of detected hydrogen light that should have been obscured. This discovery, alongside advanced simulations, sheds light on galaxy formation and evolution in the Universe’s infancy. Credit: S. Martin-AlvarezOne of the key missions of
James Webb telescope captures the most distant active supermassive black hole yet
The James Webb space telescope has given scientists the capability to discover celestial objects they wouldn't have been able to otherwise, such as ancient galaxies that theoretically shouldn't exist. Now, as part of the Cosmic Evolution Early Release Science (CEERS) Survey, researchers have discovered the most distant active supermassive black hole we've seen to date.

Webb telescope spots its first star—and takes a selfie
The first picture sent back of the cosmos is far from stunning: 18 blurry white dots on a black background, all showing the same object: HD 84406 a bright, isolated star in the constellation Ursa Major. Star light, star bright, the James Webb Space Telescope has seen its first star (though it wasn't quite tonight)—and…
Le télescope spatial Webb livre ses premières images d’une étoile de la Grande Ourse
Le télescope spatial James-Webb (Nasa) est arrivé à destination, au point dit de Lagrange dit L2, le 24 janvier dernier. Il commence à livrer des images de sa première cible, HD 84406, une étoile de type G et donc similaire au Soleil, située à environ 258 années-lumière dans la constellation de la Grande Ourse.Cela vous intéressera aussi…
