Exposed core of ancient gas giant discovered orbiting Sun-like star

Astronomers have discovered the intact, exposed core of a gas giant locked in a close orbit around a Sun-like star. The discovery will give astronomers a rare opportunity to probe the heart of an ancient alien world, and their findings could tell us mo… Continue reading Exposed core of ancient gas giant discovered orbiting Sun-like star

TESS spots closest super-Earth that could be habitable

NASA’s Transiting Exoplanet Survey Satellite (TESS) mission has been very busy lately. Back in April, the satellite discovered its first Earth-sized planet, in early July it found three more in one system, and just this week another system of… Continue reading TESS spots closest super-Earth that could be habitable

TESS completes survey of southern sky, marking halfway mark of mission

NASA’s Transiting Exoplanet Survey Satellite (TESS) is halfway through its two-year primary mission and has completed its survey of the southern sky in its search for extrasolar planets. According to the space agency, the unmanned telescope h… Continue reading TESS completes survey of southern sky, marking halfway mark of mission

White dwarf supernova observation is a first for NASA's TESS mission

Artist concept of the TESS spacecraft which recently observed a supernova and the elemental content of ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) was built to search for new planets, but astronomers at Ohio State discovered that it could also observe supernovas created by exploding white dwarf stars. This development means we might soon have a better idea about why they explode, and what they leave behind in the process.

NASA's TESS spots three new Earth-sized exoplanets orbiting nearby star

The three new planets discovered by TESS – L 98-59b, c and d – as compared ...

Three new, roughly Earth-sized exoplanets have been found orbiting a nearby star. Named L 98-59b, c and d, the small worlds were spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS), as part of a larger haul of data that finally brings the total tally past the milestone of 4,000 exoplanets discovered to date.

New algorithm digs up 18 Earth-like exoplanets from old Kepler data

So far almost 4,000 planets have been discovered orbiting stars other than the Sun, and that tally is constantly growing. Now another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Eart… Continue reading New algorithm digs up 18 Earth-like exoplanets from old Kepler data

Kepler Closes Eyes After a Decade of Discovery

Since its launch in March 2009, the Kepler Space Telescope has provided us with an incredible amount of data about exoplanets within our galaxy, proving these worlds are more varied and numerous than we could ever have imagined. Before its launch we simply didn’t know how common planets such as ours were, but today we know the Milky Way contains billions of them. Some of these worlds are so hot they have seas of molten rock, others experience two sunsets a day as they orbit a pair of stars. Perhaps most importantly, thousands of the planets found by Kepler are …read more

Scientists Want to Study Exoplanet Atmospheres for Signs of Alien Life

Instead of looking at individual biosignatures, a new dynamic framework suggests that studying atmospheric seasons may be the key for detecting alien life on exoplanets. Continue reading Scientists Want to Study Exoplanet Atmospheres for Signs of Alien Life
