Dec 18, 2022 (SPX)
The team, led by Caroline Piaulet of the Trottier Institute for Research on Exoplanets at the University of Montreal, published a detailed study of this planeta...
How the 'hell planet' got so hot
Dec 09, 2022 (SPX)
The fresh insights come thanks to a new tool called EXPRES that captured ultra-precise measurements of the starlight shining from Janssen's sun, known as Copern...
Southern hemisphere's biggest radio telescope begins search for ET signatures
Dec 02, 2022 (SPX)
The astronomers and engineers on the Breakthrough Listen team have spent the last three years developing and installing the most powerful digital instrumentatio...
Many planets could have atmospheres rich in helium, study finds
Nov 24, 2022 (SPX)
But thanks to new telescopes and methods in the past decades, we now know there are thousands and thousands of planets out there circling faraway stars, and the...
NASA's Webb reveals an exoplanet atmosphere as never seen before
Nov 23, 2022 (SPX)
While Webb and other space telescopes, including NASA's Hubble and Spitzer, previously have revealed isolated ingredients of this broiling planet's atmosphere, ...
Glass-like shells of diatoms help turn light into energy in dim conditions
Nov 23, 2022 (SPX)
"The computational model and toolkit we developed could pave the way toward mass-manufacturable, sustainable optical devices and more efficient light harvesting...
Milestone for JWST exoplanet observations: atmosphere properties in more detail than ever before
Nov 23, 2022 (SPX)
Information about clouds, first data about photochemistry, and a near-complete chemical inventory that hints at the planet's formation history - those are some ...
Detected: sulfur compound created by photochemistry in exoplanet atmosphere
Nov 23, 2022 (SPX)
Earlier this year, the same science team announced indisputable observations of atmospheric carbon dioxide around the same exoplanet. As they expanded their ana...
An exoplanet atmosphere as never seen before
Nov 23, 2022 (SPX)
The telescope's array of highly sensitive instruments was trained on the atmosphere of a "hot Saturn"-a planet about as massive as Saturn orbiting a star some 7...
Colliding magnetic fields reveal unknown planets
Nov 17, 2022 (SPX)
Exoplanets are planets that orbit around other stars than the sun. They are sometimes difficult to detect, but now it appears that interactions between exoplane...
Polluted white dwarfs show that stars and planets grow together
Nov 15, 2022 (SPX)
Planets form in a disk of hydrogen, helium and small particles of ice and dust around a young star. The dust particles clump together and grow slowly at first. ...
Early planetary migration can explain missing planets
Nov 08, 2022 (SPX)
One puzzle known as the "radius valley" refers to the rarity of exoplanets with a radius about 1.8 times that of Earth. NASA's Kepler spacecraft observed planet...
Oldest planetary debris in our galaxy found from new study
Nov 07, 2022 (SPX)
The fate of most stars, including those like our Sun, is to become a white dwarf. A white dwarf is a star that has burnt up all of its fuel and shed its outer l...
Do you speak extra-terrestrial?
Nov 03, 2022 (SPX)
While we might never learn about the existence of life beyond Earth, or even about another intelligent civilisation, there's a chance it could be detected soone...
New technique to determine age will open new era of planetary science
Oct 27, 2022 (SPX)
A group with the University of Chicago and the Field Museum of Natural History tested an instrument made by Thermo Fisher Scientific on a piece of a Martian met...
Secret behind spectacular blooms in world's driest desert is invisible to human eyes
Oct 24, 2022 (SPX)
But which physiological and evolutionary mechanisms enable the great diversity of colors, shapes, and visual patterns of flowers during desiertos floridos? And ...
Discovery could dramatically narrow search for space creatures
Oct 24, 2022 (SPX)
The work that led to the revelations about the no-atmosphere planet, named GJ 1252b, are detailed in the Astrophysical Journal Letters. This planet orbits its s...
Innovative system evaluates habitability of distant planets
Oct 20, 2022 (SPX)
A new project, led by Dr. Assaf Hochman at the Fredy and Nadine Herrmann Institute of Earth Sciences at the Hebrew University of Jerusalem (HU), in collaboratio...
Heaviest element yet detected in an exoplanet atmosphere
Oct 17, 2022 (SPX)
"The puzzling and counterintuitive part is: why is there such a heavy element in the upper layers of the atmosphere of these planets?" says Tomas Azevedo Silva,...
Blue Skies Space satellite will monitor how energy released by stars impacts exoplanet habitability
Oct 17, 2022 (SPX)
Mauve data will help scientists understand the impact of powerful stellar flares on exoplanet atmospheres and the potential of harbouring life. Blue Skies Space...
