Tidal heating could make exomoons much more habitable (and detectable)
Within the solar system, most of our astrobiological research is aimed at Mars, which is considered to be the next-most habitable body beyond Earth. However, future efforts are aimed at exploring icy satellites in the outer solar system that could al.....»»
A super-Earth (and possible Earth-sized) exoplanet found in the habitable zone
Astronomers have found a new Super-Earth orbiting an M-dwarf (red dwarf) star about 137 light-years away. The planet is named TOI-715b, and it's about 1.55 Earth's radius and is inside the star's habitable zone. There's also another planetary candida.....»»
Atmospheres in the TRAPPIST-1 system should be long gone
Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them are potentially habitable. Imagine exploring a system.....»»
Astronomers discover a super-Earth located in the habitable zone
Astronomers have discovered a type of exoplanet called a "super-Earth" located in the habitable zone of its small star - and it's right in our cosmic backyard......»»
Lopsided galaxies shed light on the speed of dark matter
In new research published in Astronomy & Astrophysics, researchers have figured out how to precisely calculate the forces that affect galaxies in tidal cycles. The next stage is to find galaxies sufficiently lopsided in the universe to study the velo.....»»
Technology alone won"t save us from the climate crisis, researcher says
If European countries rely solely on technological advances, they won't be able to limit global heating to 1.5°. Households will also need to change their lifestyles. This "inconvenient truth" is the result of calculations done by industrial ecologi.....»»
Life on Earth uses water as a solvent. What are some other options for life as we don"t know it?
There is a vast menagerie of potentially habitable worlds in the cosmos, which means the universe could be home to a diversity of life beyond what we can imagine. Creatures built on silicon rather than carbon, or organisms that breathe hydrogen inste.....»»
Astronomers detect new faint tidal disruption event
An international team of astronomers reports the detection of a new tidal disruption event (TDE) as part of All-Sky Automated Survey for SuperNovae (ASAS-SN). The newfound TDE, designated ASASSN-23bd, turns out to be the least luminous and the lowest.....»»

Efficiency asymmetry: Scientists report fundamental asymmetry between heating and cooling
A new study led by scientists from Spain and Germany has found a fundamental asymmetry showing that heating is consistently faster than cooling, challenging conventional expectations and introducing the concept of "thermal kinematics" to explain this.....»»
Research team develops anti-icing film that only requires sunlight
A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or oil coating of anti-freeze s.....»»
Chasing the light: Study finds new clues about warming in the Arctic
The Arctic, Earth's icy crown, is experiencing a climate crisis like no other. It's heating up at a furious pace—four times faster than the rest of our planet. Sandia researchers are pulling back the curtain on the reduction of sunlight reflectivit.....»»
Global heating may breach 1.5°C in 2024—here"s what that could look like
It's official: 2023 was Earth's hottest year ever recorded, beating the previous record set in 2016 by a huge margin. Last year was also the first in which the world was close to 1.5°C (1.48°C) hotter than the pre-industrial average (1850-1900). We.....»»
Vision Pro competition heating up, with Sony announcing its own device
We saw the first potential Vision Pro competitor yesterday, in the form of the $699 Xreal Air 2 Ultra – and Sony has also now announced its own device. Interestingly, it doesn’t yet appear to have a name. As with the Xreal glasses, how much co.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
Study explores the properties of a faint tidal disruption event
Using a spectral synthesis code designed to simulate conditions in interstellar matter, astronomers have explored a faint tidal disruption event (TDE) designated iPTF16fnl. Results of the study, published Dec. 29 on the pre-print server arXiv, delive.....»»

People once lived in a vast region in north-western Australia—and it had an inland sea
For much of the 65,000 years of Australia's human history, the now-submerged northwest continental shelf connected the Kimberley and western Arnhem Land. This vast, habitable realm covered nearly 390,000 square kilometers, an area one-and-a-half time.....»»
