Astrophysicists Publish a ‘Survival Guide’ for Exoplanets
Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research…
Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research…
In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the Solar System (exoplanets). Beginning in 2011, it was…
Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, are cooking up an alien atmosphere right here on Earth. In a new study, JPL scientists…
Scientists looking for signs of life beyond our solar system face major challenges, one of which is that there are hundreds of billions of stars…
TRAPPIST-1 is a system of seven Earth-sized worlds orbiting an ultra-cool dwarf star about 120 light-years away. The star, and hence its system of planets,…
Explore the plethora of planets outside our solar system with new multimedia experiences from NASA’s Exoplanet Exploration Program (ExEP). In addition to a new Exoplanet Travel Bureau…
There are about 4433 exoplanets in the latest catalogs. Their radii have generally been measured by knowing the radius of their host star and then…
Wolf 503b, an exoplanet twice the size of Earth, has been discovered by an international team using data from NASA’s Kepler Space Telescope. The find…
The conditions for life surviving on planets entirely covered in water are more fluid than previously thought, opening up the possibility that water worlds could…
The mass of a very young exoplanet has been revealed for the first time using data from the European Space Agency’s star mapping spacecraft Gaia…
Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four…
Exoplanets, planets in other solar systems, can orbit very close to their host star. When, in addition to this, the host star is much hotter…
The Earth’s building blocks seem to be built from ‘pretty normal’ ingredients, according to researchers working with the world’s most powerful telescopes. Scientists have measured…
Imagine a place where the weather forecast is always the same: scorching temperatures, relentlessly sunny, and with absolutely zero chance of rain. This hellish scenario…
Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our…
Astronomers have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist….
Earthbound detectives rely on fingerprints to solve their cases; now astronomers can do the same, using “light-fingerprints” instead of skin grooves to uncover the mysteries…
A new study provides new clues indicating that an exoplanet – that is, a planet outside the Solar System – that is 500 light-years away…
