A third planet found in binary star system

Astronomers have found a third exoplanet orbiting a binary Kepler-47 star system 3,340 light years from Earth, the first, and so far only, multi-planet circumbinary solar system discovered to date.

TESS finds its first Earth-size planet

The planet-hunting TESS spacecraft has found its first Earth-size planet orbiting a star located about 53 light years away. The star, HD 21749a, also hosts at least one other world, a warm “sub-Neptune” planet.

Harsh radiation no barrier to life on nearby exoplanets

Hopes for finding life on four rocky exoplanets relatively close to Earth have been boosted by new modelling that shows biological systems could survive the intense and prolonged bursts of X-ray and UV radiation.

Exoplanet with a mass almost 13 times that of Jupiter

Scientists have discovered a giant exoplanet with a mass almost 13 times that of Jupiter in an evolved binary system. This is the first confirmation of an exoplanet in a system of this kind.

Complex Life Might Require a Very Narrow Habitable Zone

A research into how life evolved on Earth has shown that water alone does not guarantee life – nor does the presence of oxygen gas. And that two other major biosignatures, carbon dioxide and carbon monoxide could be needed.

Newly Found Planet Could Host Primitive Life, Study Suggest

Barnard b or GJ 699 b – might have microbes or other simple life in its environment as long as there is a lot of thermal activity within the planet itself. This would theoretically provide enough energy for life to survive.

Geothermal Heating Could Make Life Possible on the exoplanet

According to new study, an extrasolar planet orbiting Barnard’s star, an M-type (red dwarf), that is just 6 light years away could actually support life, assuming the planet experiences enhanced geothermal activity.

First exoplanets discovered by NASA’s TESS mission

The three confirmed planets discovered so far using TESS are all within 100 light-years of our solar system, substantially closer than the nearly 2,700 validated worlds detected using Kepler.

Over 100 new exoplanets discovered

Japanese scientists utilized a mix of ground and space based telescopes and revealed over 100 new extrasolar planets.

Astronomers May Have Just Discovered Our Sun's Identical Twin

Recent research suggests that most, if not all, stars are born with a binary twin. Our Sun is a solitary star, but there's evidence to suggest that it did have a binary twin, once upon a time and it might have just been found.

Super-Earth found orbiting Barnard’s Star just six light years away

Studying two decades of data on Barnard’s Star, astronomers have found a rocky super-Earth with a mass of at least 2.3 times that of Earth that orbits the star every 233 days or so.

Goodbye, Kepler Space Telescope

NASA's planet-hunting telescope has run out of fuel after a nine-year mission that found more than 2,600 planets orbiting other stars along with thousands of candidate worlds.

Four Giant Planets Found Around a Very Young Star

Astronomers have discovered 4 very large gas planets orbiting a young star only 2 million years old. Looks like we need a new model of planetary formation.

First evidence of ‘exomoon’ found in Kepler data

Astronomers reviewing data collected by NASA’s Kepler space telescope have found the first evidence for a possible “exomoon” orbiting a gas giant planet 8,000 light years away.

TESS telescope discovers two new planets five months after launch

NASA's TESS, made an early discovery of "super-Earth" and "hot Earth" planets in solar systems at least 49 light-years away, marking the satellite's first discovery since its April launch.
