Nancy Grace Roman Space Telescope Fully Assembled, Launch Planned for 2026–2027
NASA has successfully completed the full assembly of the Nancy Grace Roman Space Telescope, marking a major milestone for the next-generation infrared observatory. With its powerful wide-field camera and advanced coronagraph, Roman is expected to transform our understanding of dark energy, galaxy formation, and exoplanets once it launches later thi...

Misaligned Exoplanet Is Challenging How We Think Solar Systems Form
Astronomers studying the dwarf-star system TOI-3884b have uncovered a striking anomaly: the planet’s orbit is sharply misaligned with its star’s rotation. Using multicolour transit observations, researchers detected repeated starspot-crossing events that revealed the planet passes over cooler regions on the stellar surface. Follow-up monitoring...

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...

NASA’s Nancy Grace Roman Space Telescope Surpassing Expectations Even Before Launch, Reveals Research
NASA’s upcoming Roman Space Telescope is expected to measure seismic waves in over 300,000 red giant stars, far greater than early predictions. These signals will help scientists better understand exoplanet systems and the Milky Way’s ancient core. Researchers say Roman’s natural survey design enables this breakthrough even before the telesco...

Astronomers Spot First Coronal Mass Ejection from a Distant Star, Raising Questions About Planetary Habitability
Astronomers detected the first coronal mass ejection from a distant star, revealing that powerful stellar eruptions may strip atmospheres from nearby planets, affecting exoplanet habitability and the search for life.

Planets Could Create Their Own Water While Forming, Expanding Possibilities for Habitable Worlds
Lab experiments show planets can generate water during formation, not just via comets. This suggests habitable conditions may be widespread in the galaxy, expanding possibilities for life-friendly exoplanets.

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 ...

NASA's James Webb Space Telescope Telescope Challenges Old Theories on Mini-Neptune Worlds
New models suggest mini-Neptunes—planets smaller than Neptune with thick gas envelopes—may have solid rocky surfaces instead of molten magma. Data from NASA’s JWST revealed high-pressure atmospheres capable of compressing molten rock into solid crusts. This discovery challenges earlier assumptions and offers key insights into exoplanet compos...

NASA’s JWST Produces First-Ever 3D Map of Distant Planet WASP-18b
NASA’s James Webb Space Telescope has created the first-ever 3D atmospheric map of an exoplanet, revealing the extreme conditions on WASP-18b, an “ultra-hot Jupiter” located 400 light-years away. Using infrared eclipse mapping, scientists discovered a scorching hotspot over 2,700 °C where water molecules are breaking apart. This groundbreaki...
