JWST Reveals Powerful Winds and Dense Atmosphere on Scorching Exoplanet TOI-561b
Astronomers using NASA’s James Webb Space Telescope have found compelling evidence that TOI-561b, an ultra-hot rocky exoplanet orbiting its star every 11 hours, still retains a dense atmosphere. Temperatures measured on both its day and night sides are far lower than expected for a bare rock, implying powerful winds and efficient heat transport. ...

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

The Most Exciting Exoplanet Discoveries of 2025: Know the Strange Worlds Scientists Have Found
Astronomers marked a milestone year as confirmed exoplanets surpassed 6,000 in 2025. Discoveries ranged from planets orbiting two suns to worlds losing their atmospheres or forming in real time. The findings reshaped ideas about how planets form, survive, and evolve across the Milky Way.

NASA James Webb Telescope Reveals ‘Jekyll and Hyde’ Star System Hiding a Supermassive Black Hole
For decades, astronomers have studied galaxy formation, but the James Webb Space Telescope (JWST) has now revealed a galaxy with a dual personality, earning it the nickname “Jekyll and Hyde.” Known as Virgil, the galaxy shows a mild-mannered side, forming stars quietly, while its hidden core harbours a heavily obscured supermassive black hole t...

James Webb Confirms First Runaway Supermassive Black Hole Rocking Through Space
The James Webb Space Telescope has confirmed the first runaway supermassive black hole, moving at 2.2 million mph through the Cosmic Owl galaxies. Pushing a galaxy-sized shockwave and leaving a long trail of star-forming gas, this discovery confirms long-standing theories about black hole ejections and opens the door to finding more cosmic speedste...

James Webb Space Telescope Could Illuminate Dark Matter in an Unexpected Way
New research suggests the James Webb Space Telescope could help uncover the true nature of dark matter. By observing strange, elongated galaxies in the early universe, scientists believe JWST may reveal how dark matter shaped cosmic structure, offering clues that could narrow down long-standing theories about this invisible substance.

James Webb Space Telescope Could Help Reveal Dark Matter in a Way Scientists Did Not Anticipate
New research suggests the James Webb Space Telescope could help scientists understand dark matter by studying oddly shaped early galaxies. These elongated galaxies may form due to dark matter’s gravitational behaviour, offering indirect clues about whether ultralight or warm dark matter particles shaped the early universe.

James Webb Telescope Finds Evidence Of Giant "Dinosaur" Stars From Early Universe
The research also suggests that these massive stars transformed directly into black holes at the end of their lives without undergoing a supernova explosion.

NASA Finds Thick Atmosphere On Rare Rocky Exoplanet
Scientists are now analysing the entire data in depth to create a complete map of the temperature around the planet and better understand the composition of its atmosphere.

Researchers Found Mysterious Objects That Could Be "Dark Stars"
In smaller dark stars, when their dark matter runs out, normal nuclear fusion can begin, and they gradually become normal stars.

JWST Detects Thick Atmosphere on Ultra-Hot Rocky Exoplanet TOI-561 b
Astronomers using the James Webb Space Telescope have discovered compelling evidence of a thick atmosphere surrounding TOI-561 b, an ultra-hot rocky exoplanet orbiting its star every 11 hours. Despite extreme radiation and molten surface conditions, the planet appears cooler than expected, suggesting heat-redistributing atmospheric winds and volati...

JWST Detects Oldest Supernova Ever Seen, Linked to GRB 250314A
Astronomers using the James Webb Space Telescope have detected the oldest supernova ever recorded, tied to gamma-ray burst GRB 250314A. Occurring when the universe was only 730 million years old, the explosion provides a rare glimpse into the first generations of stars and early galaxy growth, highlighting Webb’s unmatched ability to study the di...

James Webb Space Telescope Spots an Exoplanet Losing Its Atmosphere in a Huge Helium Stream
Astronomers using NASA’s James Webb Space Telescope have observed a massive helium cloud escaping from the super-puff exoplanet WASP-107b, marking the first direct detection of such atmospheric loss. Webb’s infrared data reveal an enormous exosphere nearly ten times the planet’s radius, with helium streaming both ahead of and behind the plane...

James Webb Space Telescope Finds Unexpected Ultraviolet Radiation Around Young Protostars
Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the...
