Venus and Earth provide astonishingly different views of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
Circumbinary planetary systems contain planets that orbit around two stars in the center instead of just one, like in our Solar System.
An artist’s rendition...
According to quantum mechanics, a vacuum state is populated by virtual particle pairs undergoing spontaneous creation and annihilation processes. These...
NASA’s Kepler space telescope was responsible for the discovery of over 2,700 confirmed extrasolar planets, more than half of the total number of exoplanets...
The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) is a novel software architecture utilizing a fast folding algorithm to enable...
A team of U.S. astronomers has discovered that two-thirds of the planets around M dwarfs (red dwarf stars) could be roasted by extreme tidal forces, sterilizing...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and validated a...
The newly-discovered planet has a radius of 1.03 Earth radii and a temperature between 27 and 127 degrees Celsius (81-261 degrees Fahrenheit), with the...
Gliese 1214b is a so-called mini-Neptune, a smaller, denser version of Neptune that consists of a rocky core surrounded by a thick blanket of gas.
This...
New high-resolution images of the Fomalhaut A system from the NASA/ESA/CSA James Webb Space Telescope show three debris belts extending out to 23 billion...
Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research,...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Terbium, a chemical element with the symbol Tb and atomic number 65, has never before been seen in an exoplanet atmosphere.
This illustration shows how...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
Since its launch in April 2018, NASA’s Transiting Exoplanet Survey Satellite (TESS) have mapped more than 93% of the entire sky, discovered 329 new alien...
Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
Observing magnetic star-planet interactions offers promise for determining the magnetic fields of exoplanets. Models of star-planet interactions predict...
The dayside of TRAPPIST-1b, the innermost planet in the seven-planet system TRAPPIST-1, has a temperature of about 227 degrees Celsius (441 degrees Fahrenheit),...
To facilitate studies of exo-Venus candidates, astronomers from the University of California, Riverside, the University of California, Santa Cruz, Brown...
