Gels may have given early Earth chemistry a place to organize into life
Dec 03, 2025 (SPX)
The team describes a prebiotic gel-first framework in which semi-solid gel matrices, resembling modern microbial biofilms, hosted key steps in the origin of lif...
SwRI opens NOUR lab to track chemical pathways from nebulae to planetary systems
Dec 03, 2025 (SPX)
The NOUR Laboratory will focus on the chemistry of interstellar clouds, vast regions of ice, gas and dust between stars that remain a relatively underexplored f...
Machine learning tool distinguishes signs of life from non-living compounds in space samples
Nov 27, 2025 (SPX)
In their results, scientists detected thousands of molecular peaks in each sample category - 9,475 in meteorites and 9,070 in terrestrial rocks. Key molecular d...
Moss spores withstand long term exposure outside space station
Nov 21, 2025 (SPX)
Lead author Tomomichi Fujita of Hokkaido University explained, "Most living organisms, including humans, cannot survive even briefly in the vacuum of space. How...
Water production on exoplanets revealed by pressure experiments
Nov 20, 2025 (SPX)
Horn stated, "Our experiments are the first to look at interactions between hydrogen and silicates at the pressure-temperature conditions expected at their inte...
Exoplanet map initiative earns NASA support for University of Iowa physicist
Nov 14, 2025 (SPX)
Nataf and his team will address the challenge posed by interstellar extinction, the dimming and reddening of starlight by dust, which obscures observations of e...
How to spot life in the clouds on other worlds
Nov 12, 2025 (SPX)
Cornell University researchers have created the first reflectance spectra - a color-coded key - of diverse, colorful microorganisms that live in the clouds floa...
3I/ATLAS Highlights Scale and Significance of Interstellar Objects Passing Through the Solar System
Nov 08, 2025 (SPX)
Substantial interest surrounds the potential for such objects to be associated with alien technology or intentional probes. However, understanding how object si...
Closest-ever view of planet-forming disk captured around distant star
Nov 06, 2025 (SPX)
The telescope's advanced imaging tools enabled the team to study regions close to the star that were previously out of reach. They identified a thick, transitio...
Ageing stars found to destroy nearby giant planets
Nov 06, 2025 (SPX)
The research, published in Monthly Notices of the Royal Astronomical Society, examined nearly half a million stars in the early stages of post-main sequence evo...
New study revises our picture of the most common planets in the galaxy
Nov 06, 2025 (SPX)
A new study finds that many "mini-Neptunes" - perhaps the most common planets in the galaxy - are under so much pressure from their heavy atmospheres that the s...
New experiments reveal key process forming water during planet creation
Oct 31, 2025 (SPX)
More than 6,000 exoplanets have been identified in the Milky Way, with Sub-Neptunes the most common. These worlds are less massive than Neptune, larger than Ear...
SETI uses NVIDIA IGX Thor for faster real-time signal search
Oct 29, 2025 (SPX)
With NVIDIA IGX Thor, scientists can conduct AI inference and GPU-accelerated signal analysis at the telescope. According to Luigi Cruz, Staff Engineer at the S...
Revealing Exoplanet Atmospheres with 3D Eclipse Mapping
Oct 29, 2025 (SPX)
This new effort builds on a previous two-dimensional model published in 2023, expanding the capability to leverage sensitive readings from NASA's James Webb Spa...
Multi-temperature coronal mass ejections shed light on solar system origins
Oct 28, 2025 (SPX)
The study was motivated by evidence that young Sun analogues display stellar flares and ejections much more powerful than those observed from our Sun today. The...
Hydrothermal vents may have triggered early molecular chemistry on ancient Earth
Oct 27, 2025 (SPX)
"The hypothesis is that these physical-chemical contrasts present in the vicinity of the thermal vents generate a natural voltage, as occurs between the inside ...
Newly found rocky super-Earth could become key focus in search for life
Oct 27, 2025 (SPX)
Suvrath Mahadevan, professor of astronomy at Penn State, explained, "We look for these types of planets because they are our best chance at finding life elsewhe...
Ancient White Dwarf Reveals Ongoing Planetary Consumption
Oct 24, 2025 (SPX)
Evidence for this ongoing consumption arises from the Keck Observatory's spectroscopic observations, which detected thirteen chemical elements in the star's atm...
Newly found super-Earth orbits nearby star in promising habitable zone
Oct 24, 2025 (SPX)
This newly identified exoplanet is a super-Earth, several times more massive than our own planet, and potentially rocky. The planet, named GJ 251 c, orbits an M...
Iron from deep-sea vents travels across oceans to fuel marine life
Oct 21, 2025 (SPX)
This paradox, explored in a new synthesis study from MARUM - Center for Marine Environmental Sciences at the University of Bremen, reveals how hydrothermal syst...
