NASA detects Super-Earth and says it has the “right temperature for water to form”


SuperEarth, a planet between 30 and 70% larger than our planet, has recently been detected by a NASA telescope orbiting Earth.

SuperEarth or exoplanet TOI-715 b, which is about 1.5 times the size of Earth, is located in another solar system 137 light years away.

NASA said: “That is the distance from the star that could give the planet the right temperature for liquid water to form on its surface.”

However, “for there to be surface water, of course, other factors would have to coincide, especially a suitable atmosphere.”

TOI-715 b orbits close to its star in 19 days. However, scientists do not believe it is hell since, unlike other hot exoplanets, its star, a red dwarf, is cooler and smaller than the Sun, suggesting different conditions.

The researchers published the planet’s detection in Monthly Notices of the Royal Astronomical Society. However, since we are many light years away, we can only see this distant world as a dark dot as it periodically passes in front of its red dwarf star.

And, more importantly, this world orbits within the habitable or “Goldilocks” zone, according to scientists.

Astronomers are focusing their search for habitable planets on rocky worlds orbiting cooler red dwarfs, which often have shorter orbital periods, some as short as 19 days. The Transiting Exoplanet Survey Satellite (TESS) is well suited to detect transits of these planets.

Currently, these rocky planets around red dwarfs represent the best opportunity to discover habitable conditions. The next step involves a detailed examination of TOI-715 b using the powerful James Webb Space Telescope, located approximately 1 million miles from Earth, capable of providing information about the atmospheres of distant exoplanets.

“They are actually very interesting planets,” Renyu Hu, an exoplanet researcher at NASA’s Jet Propulsion Laboratory, told Mashable in 2022.
