Stellar superflares from young red dwarfs may make conditions uninhabitable on fledgling planets, according to the new results of the Habitable Zones and...
Close encounters between stars in Omega Centauri, the only star cluster visible to the naked eye, leave little room for habitable planets, according to...
Understanding which chemical elements are present in a star in what abundances can help astronomers estimate the makeup of planets that orbit them, which...
New research from the Georgia Institute of Technology and the Harvard-Smithsonian Center for Astrophysics suggests that exoplanets Kepler-62f and Kepler-186f...
An international team of astronomers from the United States, Australia, and Brazil has identified 121 giant exoplanets in the habitable zones of their...
New observations by NASA’s Chandra X-ray Observatory indicate the two brightest stars in the triple-star system Alpha Centauri are not pummeling any...
There could be a flaw in the search for atmospheric oxygen as a signature of life around most of our nearby exoplanets. A team from the University of Washington...
Astronomers using the NASA/ESA Hubble Space Telescope have conducted the first spectroscopic survey of exoplanets within the habitable zone around TRAPPIST-1....
An international team of astronomers has found that a little-known exoplanet called K2-18b could be a scaled-up version of Earth, and also discovered the...
In a research paper to appear in the Astronomical Journal (arXiv.org preprint), astronomers from MIT, the Geneva Observatory and elsewhere report that...
According to two separate teams of astrophysicists from the Harvard-Smithsonian Center for Astrophysics (CfA) and the Lowell Center for Space Science and...
Huge coronal mass ejections (CMEs) on the Sun produce extreme space weather effects at Earth. Models of solar CMEs have now been applied to M-dwarf and...
Using numerical simulations to identify planets stable for millions of years, a team of researchers concluded that six of the seven roughly Earth-sized...
Astronomers have discovered a super-Earth exoplanet orbiting the red dwarf star Gliese 625.
This artist’s concept depicts a super-Earth-size exoplanet....
A team of astrophysicists and meteorology experts from the University of Exeter and the UK’s Met Office have embarked on the first, tentative steps to...
Exomoons around migrant hot Jupiters could hold onto life-giving atmospheres and maintain surface oceans for billions and billions of years. This is the...
Astronomers have discovered a ‘super-Earth’ exoplanet in the habitable zone of LHS 1140, a small, cool star in the constellation of Cetus, approximately...
A study by Dr. Siegfried Eggl of NASA’s Jet Propulsion Laboratory and Dr. Max Popp of Princeton University and the Max Planck Institute of Meteorology...
A team of researchers led by Vladimir Airapetian, a solar scientist at NASA’s Goddard Space Flight Center, has developed a model that estimates the oxygen...
