TESS Planet Hunter Spotted New Exoplanet That Could Support Life

Owing to NASA’s TESS Planet Hunter, scientists found an exoplanet that may have a liquid water.

The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA’s Explorers program, designed to seek for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket. Here is the photo of TESS Planet Hunter.

TESS Planet Hunter Spotted New Exoplanet That Could Support Life

This is the first time when TESS science conference taking place at MIT this week, a handful of new discoveries are slowly coming to light, including its discovery of three planets hiding around a nearby star.

Many exoplanets orbiting stars outside our solar system were found orbiting an M-dwarf star, called GJ 357 in the Hydra constellation. The first exoplanet discovered around the star was GJ 357 b.

The study was published this week in the journal Astronomy & Astrophysics.

In comparison to Earth, the exoplanet is 22% larger and 80% more massive, becoming a super-Earth. It’s 11 times closer to its star than Mercury is to our sun and the scientists indicate that it has an average temperature of 490 degrees Fahrenheit. It completes one orbit around the star every 3.9 days.

“GJ 357 d is located within the outer edge of its star’s habitable zone, where it receives about the same amount of stellar energy from its star as Mars does from the Sun,” said co-author Diana Kossakowski, an astronomer at the Max Planck Institute for Astronomy, in a NASA press release. “If the planet has a dense atmosphere, which will take future studies to determine, it could trap enough heat to warm the planet and allow liquid water on its surface.”
