Far away!
NASA has discovered a potentially habitable “super-Earth” – and it’s “only” 137 light-years away.
“By astronomical standards, that’s not too bad!” the agency insists on X about the planet called TOI-715 b.
The planet is about one and a half times larger than Earth and completes a full orbit – or “one year” – in just 19 days, NASA revealed.
More promisingly, the space rock has a “conservative” habitable zone around its parent star, meaning it may form liquid water on its surface, which would be important to support life forms.
A second, smaller planet may be nearby that is only slightly larger than Earth and may also reside within the “conservative” habitable zone, NASA reported, saying the planet “may appear at the right time.”
TOI-715 b orbits a red dwarf, which is smaller and cooler than the sun. They are known as “the best bet for finding habitable planets,” NASA said.

“These planets make much closer orbits than those around a star like our sun, but because red dwarfs are smaller and cooler, the planets can gather closer and still be safely within the star’s habitable zone,” the agency added. that.
A tighter orbit – in this case, 19 days – allows scientists to observe the planet more often.
One side of a planet always faces its star, meaning the temperature difference can be quite different.

Planet TOI-175 b joins a list of potentially habitable planets that the Webb telescope can probe for signs of an atmosphere, the space company said.
Exoplanets are worlds located outside our solar system and have been studied by the James Webb Space Telescope since 2018.
“Much will depend on other properties of the planet, including how large it is and whether it can be classified as a “water world” — making its atmosphere, if any, more prominent and much harder to detect than larger, denser and dry, likely maintaining its low-profile atmosphere closer to the surface,” NASA said.
The planet was discovered by an international team of scientists led by Georgina Dransfield from the University of Birmingham in the UK last month.
