James Webb Space Telescope discovers evidence of a new planet
Aug 07, 2025 (UPI)
The Alpha Centauri triple star system, four light-years from Earth, has long been at the center of scientists' search for life on other planets. This discovery ...
Super alcohol discovery reveals potential building block of cosmic life
Aug 06, 2025 (SPX)
Described as a "prebiotic concentrate" by Fortenberry, methanetetrol contains four hydroxyl groups attached to a single carbon atom - making it a rare type of o...
Giant rogue planets could host scaled-down planetary systems
Aug 06, 2025 (SPX)
Using data from the James Webb Space Telescope (JWST), researchers examined eight isolated planetary-mass objects between five and ten times the mass of Jupiter...
Sun dogs, other celestial effects could appear in alien skies
Aug 01, 2025 (SPX)
Similar phenomena can appear in the skies over some exoplanets of the "hot Jupiter" variety, a common type of gaseous giant that always orbits close to its host...
Chemistry that shaped the cosmos revealed in helium hydride reaction study
Jul 30, 2025 (SPX)
The earliest known molecule, the helium hydride ion (HeH+), formed when a neutral helium atom bonded with an ionized hydrogen nucleus. This triggered a sequence...
One billion years of protein evolution reveals surprising design flexibility
Jul 25, 2025 (SPX)
Scientists from the Centre for Genomic Regulation (CRG) in Barcelona and the Wellcome Sanger Institute in the UK studied the FYN-SH3 protein domain, a component...
Building blocks of life found in distant star system suggest origins in interstellar space
Jul 25, 2025 (SPX)
These findings point to a growing complexity of organic chemistry as systems evolve from cold interstellar clouds to mature planetary systems. The results chall...
Diverse rocky planets found around nearby red dwarf including one in the habitable zone
Jul 24, 2025 (SPX)
Led by researchers from the Trottier Institute for Research on Exoplanets (IREx) at Universite de Montreal, the study confirms that all five known planets in th...
Alien life clues may emerge from deep sea volcanic vents on Earth
Jul 22, 2025 (SPX)
Europa, beneath its frozen exterior, is believed to harbor a salty ocean in contact with a molten interior, potentially creating a habitable environment. "We th...
NASA Research Shows Path Toward Protocells on Titan
Jul 22, 2025 (SPX)
Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan's lakes and seas are not filled with water. Instead, they c...
Astronomers observe birth of a solar system for first time
Jul 16, 2025 (AFP)
The new planetary system is forming around the baby star HOPS-315 -- which resembles our own Sun in its youth -- 1,300 light years from Earth in the Orion Nebul...
How airports like Heathrow and Gatwick could help aliens spot Earth
Jul 11, 2025 (SPX)
The study explored how hidden electromagnetic leakage might look to extraterrestrials up to 200 light-years from Earth, if they had state-of-the-art radio teles...
James Webb reveals sub-Saturn mass exoplanet in young star system
Jul 11, 2025 (SPX)
This technology, created through a CNRS-CEA collaboration, functions by masking a star's light to reveal nearby, dimmer objects-similar to what occurs during a ...
Scientists uncover mechanism that causes formation of planets
Jul 09, 2025 (SPX)
The scientists found that the wobble could grow in a new, unexpected way. Researchers already knew that wobbles could grow from the interaction between plasma a...
Meteorite amino acid triggers nanocavity formation in common clay
Jul 08, 2025 (SPX)
The study, part of the Dutch Research Council's Planetary and ExoPlanetary Science Programme (PEPSci), adds new depth to the "warm little pond" theory. This the...
Clingy exoplanet may be triggering destructive stellar flares
Jul 07, 2025 (SPX)
The planet, HIP 67522 b, orbits its star in just seven days and is bombarded by radiation due to frequent energetic outbursts. These flares, nearly 100 times mo...
Earth sized planets frequently orbit red dwarf stars study finds
Jun 30, 2025 (SPX)
These results stem from precise radial velocity measurements captured using the CARMENES spectrograph at the Calar Alto Observatory in Spain. Designed and const...
Earth-sized planets commonly found around smallest stars reveals CARMENES data
Jun 30, 2025 (SPX)
The observations were conducted using the CARMENES spectrograph at the Calar Alto Observatory in Spain. Developed at the Konigstuhl Observatory, the instrument ...
