Ironing out the interiors of exoplanets
The discovery of more than 4,500 extra-solar planets has created a need for modelling their interior structure and dynamics. As it turns out, iron plays a key role......»»
Modeling electrolyte transport in water-rich exoplanets
Oceans on water-rich exoplanets may be enriched with electrolytes, including salts such as sodium chloride, suggests a modeling study published in Nature Communications. The research proposes electrolytes can be transported from the rocky core of the.....»»
Two rocky super-Earths discovered just 33 light-years away
Researchers using NASA's TESS satellite have discovered two rocky exoplanets in a system in our cosmic backyard, located just 33 light-years from Earth......»»
Webb"s mid-infrared spectroscopy will reveal molecules, elements
NASA's James Webb Space Telescope team continues to work its way through the 17 science instrument modes. This week they checked off numbers (5) NIRCam grism time series and (4) imaging time series, both used to study exoplanets and other time-variab.....»»
New clues about how hot Jupiters form
Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative.....»»
The stunning new planets discovered in 2022, so far
It's been a landmark year for discovering new, fascinating worlds. In 2022, NASA surpassed 5,000 confirmed exoplanets, which are alien worlds beyond our solar system. These include a diversity of distant planets, including (perhaps rocky) super-Earth.....»»
New laser breakthrough to help understanding of gravitational waves
Gravitational wave scientists from The University of Western Australia have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test fundamental limits of general r.....»»
James Webb Telescope eyes exoplanet with oceans of lava
The James Webb Space Telescope team has identified a couple of exoplanets it wants to explore, including one featuring oceans of lava......»»
AI reveals unsuspected math underlying search for exoplanets
Artificial intelligence (AI) algorithms trained on real astronomical observations now outperform astronomers in sifting through massive amounts of data to find new exploding stars, identify new types of galaxies and detect the mergers of massive star.....»»
CHES survey could detect exoplanets within a few dozen light-years of Earth using astrometry
NASA has indicated that 5,030 extrasolar planets have been confirmed in 3,772 systems, with another 8,974 candidates awaiting confirmation. With next-generation instruments like the James Webb Space Telescope (JWST) coming online, the number and dive.....»»
Even stars doomed to die as supernovae can have planets
Ninety percent of all exoplanets discovered to date (there are now more than 5,000 of them) orbit around stars the same size or smaller than our sun. Giant stars seem to lack planetary companions, and this fact has serious implications for how we und.....»»
Team finds younger exoplanets are better candidates when looking for other Earths
As the scientific community searches for worlds orbiting nearby stars that could potentially harbor life, new Southwest Research Institute-led research suggests that younger rocky exoplanets are more likely to support temperate, Earth-like climates......»»
Scientists describe a gravity telescope that could image exoplanets
In the time since the first exoplanet was discovered in 1992, astronomers have detected more than 5,000 planets orbiting other stars. But when astronomers detect a new exoplanet, we don't learn a lot about it: We know that it exists and a few feature.....»»
Hubble spies on 25 hot Jupiters to learn about their atmospheres
The Hubble Space Telescope have investigated 25 exoplanets to find out about how the composition of their atmospheres......»»
Two rocky exoplanets discovered around nearby star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected two rocky alien worlds orbiting a nearby M dwarf star known as HD 260655. The newly found exoplanets are larger and at least two times more massive than the Earth. T.....»»
This extreme exoplanet’s atmosphere is being sunburned by its host star
Some of the most extreme exoplanets we've found are a type called hot Jupiters, where high temperatures lead to some weird and wonderful effects......»»
Hubble probes extreme weather on ultra-hot Jupiters
In studying a unique class of ultra-hot exoplanets, NASA Hubble Space Telescope astronomers may be in the mood for dancing to the Calypso party song "Hot, Hot, Hot." That's because these bloated Jupiter-sized worlds are so precariously close to their.....»»
There"s 5,000 known exoplanets beyond our solar system. Here"s what that sounds like.
The number of known exoplanets officially passed 5,000 on Monday, with NASA confirming the discovery of 65 new worlds. Do you want to hear what that...sounds like?Created by Toronto-based musicians Andrew Santaguida and Matt Russo of SYSTEM Sounds, i.....»»
NASA Confirms 5,000 Exoplanets
NASA JPL announced a cosmic milestone with the confirmed discovery of over 5,000 exoplanets (planets located outside our solar system). CNET reports: A new batch of 65 planets joined the NASA Exoplanet Archive on Monday, triggering a celebratory mood.....»»
Smaller, ground-based telescopes can study exoplanet atmospheres, too
The next step to understanding exoplanets is to understand their atmospheres better. Astronomers can determine a planet's mass, density, and other physical characteristics fairly routinely. But characterizing their atmospheres is more complicated......»»
Among thousands of known exoplanets, astronomers flag three that are actually stars
The first worlds beyond our solar system were discovered three decades ago. Since then, close to 5,000 exoplanets have been confirmed in our galaxy. Astronomers have detected another 5,000 planetary candidates—objects that might be planets but have.....»»
