NASA Webb probes atmosphere scenarios for TRAPPIST-1 e
Sep 19, 2025 (SPX)
TRAPPIST-1 e lies in its star's habitable zone, where surface water is theoretically possible. Webb's Near-Infrared Spectrograph (NIRSpec) captured light as the...
Molecular 'fossils' offer microscopic clues to the origins of life - but they take care to interpret
Sep 19, 2025 (SPX)
In our work as evolutionary biochemists and protein historians, these core questions form the foundation of our research programs. To study life's history billi...
What 3I/ATLAS tells us about other solar systems
Sep 17, 2025 (SPX)
Even before the comet was discovered in early July, it was hiding among the stars, too faint to be noticeable. In a new paper published in the Astrophysical Jou...
Planet transits across starspots reveal tilted orbit in TOI-3884 system
Sep 17, 2025 (SPX)
The changing shapes of the spot-crossing signals suggested stellar rotation rather than spot evolution. To confirm this, the researchers conducted a photometric...
Alien civilizations may be far rarer than hoped study suggests
Sep 17, 2025 (SPX)
Dr Manuel Scherf and Professor Helmut Lammer of the Austrian Academy of Sciences argue that the odds of finding advanced life are severely constrained by planet...
Spacecraft study shows interstellar comet encounter mission within reach
Sep 07, 2025 (SPX)
The first known interstellar comet, 1I/'Oumuamua, was discovered in 2017, followed by 2I/Borisov in 2019. The arrival of 3I/ATLAS this year reinforced predictio...
UMD-led study discovers warm space dust in distant place
Sep 07, 2025 (SPX)
A research team led by University of Maryland Astronomy Professor Sylvain Veilleux used the James Webb Space Telescope (JWST) to study these resilient dust part...
Advancing Single-Photon Sensing Image Sensors to Enable the Search for Life Beyond Earth
Sep 03, 2025 (SPX)
Are we alone in the universe? This age-old question has inspired scientific exploration for centuries. If life on other planets evolves similarly to life on Ear...
Circle versus rectangle: Finding 'Earth 2.0' may be easier using a new telescope shape
Sep 02, 2025 (SPX)
All of this suggests that life might be common on planets that support liquid water, but it might be uncommon to find life that studies the universe and seeks t...
Warped planet forming discs challenge long held models of planetary birth
Sep 01, 2025 (SPX)
The research team, using the Atacama Large Millimetre/submillimetre Array (ALMA) as part of the exoALMA programme, discovered that many discs tilt by just half ...
A growing baby planet photographed for first time in a ring of darkness
Sep 01, 2025 (SPX)
The team, led by University of Arizona astronomer Laird Close and Richelle van Capelleveen, an astronomy graduate student at Leiden Observatory in the Netherlan...
Astronomers puzzled by carbon-loaded protoplanetary disk
Sep 01, 2025 (SPX)
"Unlike most nearby planet-forming disks, where water vapor dominates the inner regions, this disk is surprisingly rich in carbon dioxide," said lead author Jen...
Surprising carbon dioxide-rich disk challenges planet theory
Sep 01, 2025 (SPX)
Lead author Jenny Frediani, a PhD student at Stockholm University's Department of Astronomy, said: "Unlike most nearby planet-forming disks, where water vapor d...
Clues from Butterfly Nebula dust advance knowledge of rocky planet origins
Sep 01, 2025 (SPX)
Lead researcher Dr Mikako Matsuura of Cardiff University said: "For years, scientists have debated how cosmic dust forms in space. But now, with the help of the...
JWST observes planetary building blocks in Butterfly Nebula
Aug 28, 2025 (UPI)
The telescope saw the creation of tiny planetary building blocks around a dead star, as it saw cosmic dust particles that create planets around young stars form...
Mapping star spots with NASA missions offers new insight into exoplanets
Aug 26, 2025 (SPX)
Lead researcher Sabina Sagynbayeva of Stony Brook University explained that many exoplanet studies assume stars are evenly bright disks. "But we know just by lo...
Model brings clarity to water rich exoplanets called steam worlds
Aug 26, 2025 (SPX)
But because these types of exoplanets tend to be much closer to their host star than Earth is to the Sun, sub-Neptunes are too hot to have liquid water on their...
TRAPPIST-1 d ruled out as Earth twin by Webb study
Aug 15, 2025 (SPX)
The finding narrows the search for worlds with conditions similar to Earth, according to lead author Caroline Piaulet-Ghorayeb of the University of Chicago and ...
Planets without water could still produce certain liquids
Aug 13, 2025 (SPX)
But what makes some planets habitable might have very little to do with water. In fact, an entirely different type of liquid could conceivably support life in w...
Hints emerge of giant planet orbiting Alpha Centauri A
Aug 08, 2025 (SPX)
Using Webb's Mid-Infrared Instrument (MIRI) in August 2024, researchers employed a coronagraphic mask to block Alpha Centauri A's light, revealing an object ove...
