Astronomers Use Webb Telescope to Study Exoplanet Surface Beyond Atmosphere
Using James Webb Space Telescope, astronomers directly measured heat from LHS 3844 b, revealing a dark, rocky surface with no atmosphere—more like Mercury than Earth—marking a breakthrough in studying exoplanet geology.

James Webb Telescope Captures Stunning Infrared View of Exposed Cranium Nebula
NASA’s James Webb Space Telescope has captured remarkably detailed infrared images of PMR 1, known as the “Exposed Cranium,” a planetary nebula roughly 5,000 light-years away in the constellation Vela. The observations reveal a glowing inner “brain” region surrounded by a hydrogen gas shell, divided by a dark lane of ejected material, pro...

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.

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...

Webb Finds Phosphorus-Bearing Gas in an Ancient Brown Dwarf
NASA’s James Webb Space Telescope has detected phosphine (PH₃) in the atmosphere of the ancient brown dwarf Wolf 1130C, about 54 light-years away in Cygnus. This marks the first confirmed detection of a phosphorus-bearing gas in such a metal-poor object. The finding surprises astronomers, as phosphine was previously undetected in similar brown ...

James Webb Offers First Glimpse Into How Moons Are Built Around Distant Planets
The James Webb Space Telescope has detected carbon-bearing molecules in a moon-forming disk surrounding CT Cha b, a massive planet-like object orbiting a young star 625 light-years away. The discovery marks the first measurement of its kind and offers clues to how moons like those around Jupiter and Saturn might have formed.

SpaceX Launches Falcon 9 Rocket With 28 Starlink Satellites Into Orbit From Florida
SpaceX’s Falcon 9 rocket launched 28 Starlink satellites into low-Earth orbit from Florida, marking the company’s 34th Starlink mission for 2025. The booster B1080 landed successfully on a drone ship after its 18th flight. These new satellites will expand the Starlink megaconstellation, bringing high-speed internet access to more parts of the g...

SpaceX Launches Two SES Communication Satellites on December 17 with Successful Recovery
On December 17, SpaceX successfully launched two communication satellites for SES, marking the second mission of the day. The O3b mPOWER 7 and 8 satellites were deployed into medium Earth orbit (MEO) approximately 5,000 miles above Earth. The Falcon 9 rocket’s first stage successfully returned to Earth after launch, landing on the Just Read the I...

Hubble Captures Images of a Galaxy Whose Outer Edges 'Resemble a Ship's Sails'
Hubble Space Telescope provides astronomers with breathtaking images of the cosmos for deeper studies. Recently, the telescope shared yet another strikingly beautiful image. This time, it captured the NGC 3318 galaxy, which lies in the constellation Vela, located about 115 million light-years away from the Earth.
