TESS celebrates fifth year scanning the sky for new worlds
Apr 20, 2023 (ESA)
Using its four cameras, TESS monitors large swaths of the sky called sectors for about a month at a time. Each sector measures 24 by 96 degrees, about as wide a...
HD 169142 b, the third protoplanet confirmed to date
Apr 18, 2023 (SPX)
Planets form from clumps of material in discs surrounding newborn stars. When the planet is still forming, i.e. when it is still gathering material, it is calle...
International team discover new exoplanet partly using direct imaging
Apr 18, 2023 (SPX)
In a paper slated for publication April 14 in Science, Currie reports the first exoplanet jointly discovered through direct imaging and precision astrometry, a ...
Webb peeks into the birthplaces of exoplanets
Apr 18, 2023 (SPX)
New observations towards a sample of planet-forming disks around young stars obtained with the Mid-Infrared Instrument (MIRI) on board the James Webb Space Tele...
Do Earth-like exoplanets have magnetic fields
Apr 04, 2023 (SPX)
Researchers Sebastian Pineda and Jackie Villadsen observed a repeating radio signal emanating from the star YZ Ceti using the Karl G. Jansky Very Large Array, a...
New paper investigates exoplanet climates
Mar 31, 2023 (SPX)
"Sporadic Spin-Orbit Variations in Compact Multi-planet Systems and their Influence on Exoplanet Climate," a study by Florida Tech exoplanetary scientist and as...
JWST confirms giant planet atmospheres vary widely
Mar 28, 2023 (SPX)
Using NASA's James Webb Space Telescope (JWST), the researchers discovered that the atmosphere of exoplanet HD149026b, a 'hot Jupiter' orbiting a star comparabl...
Planet hunting and the origins of life
Mar 28, 2023 (SPX)
Degrees in pocket, Ricker returned to MKI as a research scientist. Then, as now, much of his research was devoted to developing solid-state photon detectors bas...
Webb measures temperature of rocky exoplanet for first time
Mar 27, 2023 (AFP)
When the Trappist-1 system was discovered in 2017, astronomers were excited at the prospect that some of its seven rocky planets -- which are roughly similar to...
Small stars may host bigger planets than previously thought
Mar 27, 2023 (SPX)
Gas giants, like other planets, form from disks of material surrounding young stars. According to core accretion theory, they first form a core of rock, ice and...
Researchers detect silicate clouds, methane, water, carbon monoxide on distant planet
Mar 23, 2023 (UPI)
The discovery is the most number of different molecules ever seen collected on one planet outside of our solar system, scientists say. Researchers lead by the U...
Searching for life with space dust
Mar 23, 2023 (SPX)
When you hear the words vacuum and dust in a sentence, you may groan at the thought of having to do the housework. But in astronomy, these words have different ...
Webb Telescope spots swirling, gritty clouds on remote planet in spectrum data
Mar 23, 2023 (SPX)
Cataloged as VHS 1256 b, the planet is about 40 light-years away and orbits not one, but two stars over a 10,000-year period. "VHS 1256 b is about four times fa...
Hunting Venus 2.0: Scientists sharpen their sights
Mar 23, 2023 (SPX)
If they succeed in locating one, it could reveal valuable insights into Earth's future, and our risk of developing a runaway greenhouse climate as Venus did. Sc...
Scientists have new tool to estimate how much water might be hidden beneath a planet's surface
Mar 21, 2023 (SPX)
Scientists from the University of Cambridge now have a way to estimate how much water a rocky planet can store in its subterranean reservoirs. It is thought tha...
RNA base in asteroid samples suggests origins of life on Earth
Mar 21, 2023 (AFP)
Scientists have discovered the chemical compound uracil, one of the building blocks of RNA, in just 10 milligrammes of material from the asteroid Ryugu, accordi...
Terminator zones on distant planets could harbor life
Mar 17, 2023 (SPX)
"These planets have a permanent day side and a permanent night side," said Ana Lobo, a postdoctoral researcher in the UCI Department of Physics and Astronomy wh...
Dragonfly Mass Spectrometer could reveal chemistry leading to life on Titan
Mar 17, 2023 (SPX)
Titan's abundant complex carbon-rich chemistry, interior ocean, and past presence of liquid water on the surface make it an ideal destination to study prebiotic...
How do microbes live off light
Mar 13, 2023 (SPX)
Rhodopsins are the light-driven proton pumps that bacteria employ to produce ATP. Whereas photosynthesis is a process that involves multiple stages and proteins...
