May 24, 2023 (SPX)
As part of the project, on May 24, 2023, the European Space Agency's ExoMars Trace Gas Orbiter (TGO) in orbit around Mars will transmit an encoded message to Ea...
NASA's Spitzer, TESS find potentially volcano-covered Earth-size world
May 18, 2023 (SPX)
They found and studied the planet using data from NASA's TESS (Transiting Exoplanet Survey Satellite) and retired Spitzer Space Telescope, as well as a suite of...
Astronomers observe the first radiation belt seen outside of our solar system
May 16, 2023 (SPX)
"We are actually imaging the magnetosphere of our target by observing the radio-emitting plasma-its radiation belt-in the magnetosphere. That has never been don...
Researchers uncover how primordial proteins formed on prebiotic earth
May 15, 2023 (SPX)
To do so, they dried down amino acid solutions containing boric acid and found that boric acid catalyzes polypeptide synthesis under neutral and acidic conditio...
Astronomers spot benzene in planet-forming disk around star for first time
May 12, 2023 (SPX)
The researchers studied the young, small star J160532 (one tenth of the mass of our sun) some 500 light years away from us towards the constellation Scorpio. Ar...
Bacteria survive on radioactive elements
May 12, 2023 (SPX)
Lanthanides belong to the rare earth elements widely used in electronics and energy technologies. With one exception, they are not radioactive, they are abundan...
Researchers measure the light emitted by a sub-Neptune planet's atmosphere for the first time
May 11, 2023 (SPX)
NASA's new James Webb Space Telescope (JWST) solved that issue. The telescope's infrared technology allows it to see planetary objects and features that were pr...
Invading insect could transform Antarctic soils
May 11, 2023 (SPX)
Research by experts at the University of Birmingham in collaboration with the British Antarctic Survey has revealed that a non-native midge species is significa...
Webb takes closest look yet at mysterious planet
May 11, 2023 (JPL)
And while the planet, called GJ 1214 b, is too hot to harbor liquid-water oceans, water in vaporized form still could be a major part of its atmosphere. "The pl...
Webb looks for Fomalhaut's asteroid belt and finds much more
May 09, 2023 (SPX)
The Hubble Space Telescope and Herschel Space Observatory, as well as the Atacama Large Millimeter/submillimeter Array (ALMA), have previously taken sharp image...
Hubble follows shadow play around planet-forming disk
May 05, 2023 (SPX)
But a clock has two hands (hours and minutes) sweeping around at different rates. And, it turns out, so does TW Hydrae. Astronomers used Hubble to find a second...
Hunting for life's building blocks at minus 250 degrees Celsius
May 05, 2023 (SPX)
Imagine the headlights of a car on a misty day. A beam of light becomes visible in the fog, revealing particles of moisture floating in the air, absorbing and r...
Can ET detect us
May 03, 2023 (SPX)
Saide believes that unless an alien civilization is much more advanced than ours, they would have difficulty detecting the current levels of mobile tower radio ...
A stormy, active sun may have kickstarted life on Earth
May 03, 2023 (SPX)
A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basi...
Massive radio array to search for ET signals from other civilizations
May 02, 2023 (SPX)
"The VLA is the go-to instrument for radio astronomers, but this is the first time we are using it in a wide-ranging and continuous search for technosignatures,...
Webb finds water vapor, but from a rocky planet or its star
May 02, 2023 (SPX)
Such stars are also active, particularly when they are young, releasing ultraviolet and X-ray radiation that could destroy planetary atmospheres. As a result, o...
Scientists discover rare element in exoplanet's atmosphere
Apr 27, 2023 (SPX)
KELT-9 b is the galaxy's hottest exoplanet, orbiting its distant star about 670 light years from Earth. The celestial body, with an average temperature of a sta...
UGA researchers discover new planet outside solar system
Apr 26, 2023 (SPX)
A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around ne...
