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...
Astronomers have classified extrasolar planets in the same way that biologists identify new species and have learned that the majority of planets found...
Dr. Jessie Christiansen, a staff scientist at the NASA Exoplanet Science Institute, and colleagues have discovered a ‘super-Earth’ exoplanet orbiting...
Using numerical simulations to identify planets stable for millions of years, a team of researchers concluded that six of the seven roughly Earth-sized...
A newly-discovered Jupiter-like exoplanet called KELT-9b is only 2,000 degrees Fahrenheit (927 degrees Celsius, or 1,200 degrees Kelvin) cooler than our...
Astronomers have used the NASA/ESA Hubble Space Telescope to track the two components of Luhman 16AB, the third closest system to the Solar System.
This...
Astronomers have discovered a super-Earth exoplanet orbiting the red dwarf star Gliese 625.
This artist’s concept depicts a super-Earth-size exoplanet....
Astronomers have used data gathered by K2, the second mission of NASA’s Kepler Space Telescope, to confirm details of TRAPPIST-1h, the outermost of seven...
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...
A multinational team of astronomers led by Lehigh University researcher Joshua Pepper has discovered a ‘styrofoam’-density exoplanet orbiting the bright...
The recently discovered TRAPPIST-1 planetary system has a unique configuration, according to new research from the University of Toronto, Canada.
This...
A team of astronomers led by the Carnegie Institution has discovered that what scientists had previously thought was one of the closest brown dwarfs to...
New observations from the joint German-U.S. Stratospheric Observatory for Infrared Astronomy (SOFIA), the largest airborne observatory in the world, indicate...
Exomoons around migrant hot Jupiters could hold onto life-giving atmospheres and maintain surface oceans for billions and billions of years. This is the...
Using a planet-hunting technique called gravitational microlensing, astronomers have detected an Earth-mass planet orbiting an ultracool dwarf 12,750 light-years...
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...
