SuperEarth

Astronomers have discovered a super-Earth, TOI-715 b, in a potentially habitable zone around a red dwarf star 137 light-years away. This planet, which is about one and a half times the size of Earth, could support liquid water if other conditions, such as a suitable atmosphere, are met. (Artist’s concept.)

NASA says it has discovered evidence of a nearby super-Earth that is located within its star’s habitable zone. Its unique location means that the super-Earth could possibly be habitable, meaning it could hold evidence of alien life.The planet is known as TOI-0715 b, and it’s about one and a half times as wide as our own planet, NASA explains. The planet orbits within the “conservative” habitable zone of its parent star, and that means it could be the right temperature for liquid water to form on the planet’s…

NASA has made a significant discovery of a ‘super-Earth’ planet named TOI-715b, located 137 light-years away in the habitable zone, suggesting it could be a potential candidate for hosting life. The exoplanet is 1.5 times larger than Earth and orbits a small, reddish star that emits temperatures suitable for liquid water to exist on the surface — a crucial component for supporting life. Scientists, led by the University of Birmingham, utilized Earth-based telescopes in conjunction with NASA’s…

Astronomers have found a new Super-Earth orbiting an M-dwarf (red dwarf) star about 137 light-years away.The planet is named TOI-715b, and it's about 1.55 Earth's radius and is inside the star's habitable zone. There's also another planetary candidate in the system. It's Earth-sized, and if it's confirmed, it will be the smallest habitable zone planet TESS has discovered so far.TOI-715 is an average red dwarf. It's about one-quarter the mass and about one-quarter the radius of our Sun. TOI-715b is close to the star, and…

The green region represents the habitable zone where liquid water can exist on the planetary surface. The planetary orbit is shown as a blue line. Ross 508 b skims the inner edge of the habitable zone (solid line), possibly crossing into the habitable zone for part of the orbit (dashed line).

An exoplanet just 100 light-years from Earth appears to be the best candidate yet for a sloshy, water-covered ocean world.It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. Scientists believe that worlds like this are possible, but they haven't yet conclusively found one.We'll need to follow up with observations from the James Webb Space Telescope to study the exoplanet's atmosphere and make a more confident ruling on the nature of TOI-1452b, but…
