Tidying up planetary nurseries
Nov 08, 2021 (SPX)
Planets form inside disks made of gas and dust. Each of those disks already gave birth to a new star, or, for that matter, to a predecessor that still has to ig...
To find life on other planets, NASA rocket team looks to the stars
Nov 05, 2021 (SPX)
Using an updated instrument first launched in 2019, the mission has a new target: Procyon A, the brightest star in the constellation Canis Minor. But its questi...
Rocky Exoplanets Are Even Stranger Than We Thought
Nov 03, 2021 (SPX)
These are the dense, collapsed cores of once-normal stars like the Sun that contain foreign material from planets, asteroids, or other rocky bodies that once or...
Key role of the reactor surface in Miller's experiment on the molecular origin of life
Nov 03, 2021 (SPX)
Miller built a glass apparatus into which he poured water to simulate the early ocean and a mixture of gases (methane, ammonia, and hydrogen) to emulate the ear...
Building planets from protoplanetary disks
Nov 02, 2021 (SPX)
In our Solar system, for example, all the rocky planets and planetesimals contain near-solar proportions of refractory elements (elements like aluminum that con...
Scientists measure the atmosphere of a planet 340 light-years away
Oct 28, 2021 (SPX)
The team is led by Assistant Professor Michael Line of Arizona State University's School of Earth and Space Exploration, and the results have been recently publ...
Searching for Earth 2 zoom in on a star
Oct 28, 2021 (SPX)
A new technique developed by an international team of researchers - led by Yale astronomers Rachael Roettenbacher, Sam Cabot, and Debra Fischer - uses a combina...
Are we alone in the Universe? NASA calls for a New Framework
Oct 28, 2021 (SPX)
NASA scientists are encouraging the scientific community to establish a new framework that provides context for findings related to the search for life. Writing...
The upside-down orbits of a multi-planetary system
Oct 28, 2021 (SPX)
Why so? This radically different configuration from our solar system could be due to the influence of a distant companion of the star that is still unknown. Thi...
How to find hidden oceans on distant worlds? use chemistry
Oct 28, 2021 (SPX)
In our solar system, planets are either small and rocky (like Earth) or large and gaseous (like Neptune). But around other stars, astronomers have found planets...
Breakthrough Listen releases analysis of previously detected signal
Oct 26, 2021 (SPX)
"The significance of this result is that the search for civilizations beyond our planet is now a mature, rigorous field of experimental science," said Yuri Miln...
Could this be a planet in another galaxy?
Oct 26, 2021 (SPX)
Because the light from another galaxy is packed into a tiny area on the sky, it is very difficult for telescopes to distinguish one star from another, let alone...
Permafrost thaw could release bacteria and viruses
Oct 26, 2021 (ESA)
As part of the ESA-NASA Arctic Methane and Permafrost Challenge, new research has revealed that rapidly thawing permafrost in the Arctic has the potential to re...
Astronomers provide 'Field Guide' to Exoplanets known as Hot Jupiters
Oct 25, 2021 (SPX)
While previous studies mostly focused on individual worlds classified as "hot Jupiters" due to their superficial similarity to the gas giant in our own solar sy...
NEID Spectrometer Lights Up Path to Exoplanet Exploration
Oct 21, 2021 (SPX)
The NEID spectrometer, which will help locate and characterize new worlds, observes the sky from Kitt Peak National Observatory in Arizona. It began its search ...
Researchers call for armchair astronomers to help find unknown hidden worlds
Oct 19, 2021 (SPX)
The online citizen project, hosted by Zooniverse.org, Planet Hunters Next-Generation Transit Search (NGTS), is enlisting the help of the public to examine five ...
Scientists find evidence the early solar system harbored a gap between its inner and outer regions
Oct 18, 2021 (SPX)
A new analysis of ancient meteorites by scientists at MIT and elsewhere suggests that a mysterious gap existed within this disk around 4.567 billion years ago, ...
NASA scientist looks to AI, lensing to find masses of free-floating planets
Oct 07, 2021 (SPX)
Most exoplanets discovered to date were found because they produce slight dips in the observed light of their host stars as they pass across the star's disk fro...
First planet to orbit 3 Stars discovered
Oct 05, 2021 (SPX)
Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed the novel pheno...
'Planet confusion' could slow Earth-like exoplanet exploration
Oct 01, 2021 (SPX)
A new Cornell study finds that next-generation telescopes used to see exoplanets could confuse Earth-like planets with other types of planets in the same solar ...
