Surprise finding suggests 'water worlds' are more common than we thought
Sep 09, 2022 (SPX)
A new study suggests that many more planets may have large amounts of water than previously thought-as much as half water and half rock. The catch? All that wat...
Two new rocky worlds around an ultra-cool star
Sep 08, 2022 (SPX)
Most of the planets that have been discovered around other stars - also known as exoplanets - are bad candidates for life as we know it. They are either scorchi...
SPECULOOS discovers a potentially habitable super-Earth
Sep 08, 2022 (SPX)
A first planet, LP 890-9b (or TOI-4306b), the innermost in the system, was initially identified by NASA's Transiting Exoplanet Survey Satellite (TESS), a space ...
Astronomers show massive stars can steal Jupiter-sized planets
Sep 07, 2022 (SPX)
Researchers from the University of Sheffield have proposed a novel explanation for the recently discovered B-star Exoplanet Abundance STudy (BEAST) planets. The...
RIT scientists to study molecular makeup of planetary nebulae using radio telescopes
Sep 06, 2022 (SPX)
Planetary nebulae are the remnants of stars roughly one-to-eight times the size of the sun surrounded by hot gas lit up by ultraviolet radiation. Kastner hopes ...
Webb takes its first exoplanet image
Sep 02, 2022 (ESA)
The exoplanet in Webb's image, called HIP 65426 b, is about six to eight times the mass of Jupiter. It is young as planets go - about 15 to 20 million years old...
UVA joins Artemis missions to seek traces of extraterrestrial life
Sep 02, 2022 (SPX)
The new collaborative research will take the form of a roving, ground-level probe. It won't be done in time for this first unmanned launch, of course. The space...
VLBA produces first full 3-D view of binary star-planet system
Sep 02, 2022 (SPX)
Though more than 5,000 extrasolar planets have been discovered so far, only three have been discovered using the technique - called astrometry - that produced t...
Webb Telescope takes its first-ever direct image of an exoplanet
Sep 02, 2022 (SPX)
The image, as seen through four different light filters, shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system, pointing the...
Webb detects carbon dioxide in exoplanet atmosphere
Aug 26, 2022 (ESA)
WASP-39 b is a hot gas giant with a mass roughly one quarter that of Jupiter (about the same as Saturn) and a diameter 1.3 times that of Jupiter. Its extreme pu...
JWST makes first unequivocal detection of carbon dioxide in an exoplanet atmosphere
Aug 26, 2022 (SPX)
The discovery, accepted for publication in Nature and posted online August 25, demonstrates the power of the James Webb Space Telescope (JWST) to deliver unprec...
An extrasolar world covered in water
Aug 26, 2022 (SPX)
The exoplanet, known as TOI-1452 b, is slightly greater in size and mass than Earth and is located at distance from its star where its temperature would be neit...
Webb telescope finds CO2 for first time in exoplanet atmosphere
Aug 25, 2022 (AFP)
Although the exoplanet would never be able to support life as we know it, the successful discovery of CO2 gives researchers hope that similar observations could...
New study examines how many moons an earth-mass planet could host
Aug 24, 2022 (SPX)
The study, titled "Moon-packing around an Earth-mass planet", was published in the August 1 online edition of the Monthly Notices of the Royal Astronomical Soci...
Case solved: missing carbon monoxide was hiding in the ice
Aug 24, 2022 (SPX)
But for the last decade or so, something hasn't been adding up when it comes to carbon monoxide observations, says Diana Powell, a NASA Hubble Fellow at the Cen...
Breaking in a new planet
Aug 23, 2022 (SPX)
Studying how those impacts affect planetary bodies, asteroids, moons and other rocks in space helps planetary scientists including Brandon Johnson, associate pr...
Brightest stars in the night sky can strip Neptune-sized planets to their rocky cores
Aug 15, 2022 (SPX)
Few have been discovered around even more massive stars, such as A-type stars - bright blue stars twice as large as the sun - and most of the exoplanets that ha...
A cosmic tango points to a violent and chaotic past for distant exoplanet
Aug 08, 2022 (SPX)
For most people, such thoughts conjure up systems that mirror the Solar System: planets orbiting a host star on near-circular orbits - rocky planets closer in, ...
New research on the emergence of the first complex cells challenges orthodoxy
Aug 08, 2022 (SPX)
Then, something remarkable and unprecedented took place. A new type of cell, known as a eukaryote, emerged. The eukaryotes would evolve many complex internal mo...
Super-earth skimming habitable zone of red dwarf
Aug 02, 2022 (SPX)
Red dwarfs, stars smaller than the Sun, account for three-quarters of the stars in the Milky Way Galaxy, and are abundant in the neighborhood around the Sun. As...
