Fast Radio Bursts: Why a Distant Flash of Radio Waves Points to Magnetars
A recent James Webb Space Telescope observation of the most distant Fast Radio Burst (FRB) to date has provided strong evidence favoring the magnetar model for its origin. The host galaxy's youth and active star formation align with the expected environment for magnetars, while contradicting the long delay required for neutron star mergers.
How Do Supermassive Black Holes Shape Galaxy Evolution?
In one of the earliest observed galaxies, the central black hole makes up at least two-thirds of its total mass—a proportion thousands of times greater than in nearby galaxies today.
James Webb Telescope Reveals 'Treasure Chest' with 70 Young Stars
The 'Treasure Chest' star cluster in the Carina Nebula, once thought to be a mere 100,000 years old, has been dramatically re-aged by the James Webb Space Telescope to a surprising 1.
James Webb Telescope spots supernova from universe's dawn
The universe was just 730 million years old when a massive star exploded, a cosmic event now confirmed by the James Webb Space Telescope.
James Webb spots mysterious Little Red Dots in the early universe
Over 300 mysterious 'Little Red Dots' (LRDs) have been spotted by the James Webb Space Telescope (JWST), appearing just a billion years after the Big Bang.
Scientists detect potential signs of life on distant exoplanet
Despite headlines celebrating the detection of dimethyl sulfide on the distant exoplanet K2-18b, a recent survey reveals astrobiologists are actually more persuaded by potential biosignatures found in
Webb telescope studies thousands of nearby star clusters
In a distant, strongly lensed galaxy, the James Webb Space Telescope has uncovered 'Firefly Sparkle' — 10 star clusters so massive and dense they exceed anything seen in our own Milky Way.
