An international team of scientists says information technology has
discovered ii new “super-Earth” type planets about 100 light-years away, one of which may exist suitable for life.
Unlike whatever of the planets in our solar arrangement, the near one,600 known super-Earths are larger than Earth, but lighter than icy planets like Uranus and Neptune.
Researchers at Kingdom of belgium’s University of Liège announced Wednesday
that they found another one
while using Earth-based telescopes to confirm the beingness of a different planet initially discovered by a NASA satellite in the same solar system.
NASA’south satellite found planet LP 890-9b, which is near xxx% larger than Earth and orbits its sunday in just 2.seven days. ULiège researchers used their SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) telescopes in Chile and Espana to take a closer look at the planet with high-precision cameras.
That’s when the stargazers discovered another planet, LP 890-9c (renamed SPECULOOS-2c by the ULiège researchers), which is forty% larger than Globe and takes 8.5 days to orbit its sun.
Francisco Pozuelos, a researcher at the Plant of Astrophysics of Andalusia and 1 of the principal co-authors of the paper, said in a news release that the planet could be suitable to life despite being a mere 3.7 one thousand thousand miles from its sun. Earth, by comparison, is located over 93 million miles abroad from our sun.
“Although this planet orbits very close to its star, at a distance near 10 times shorter than that of Mercury around our Dominicus, the amount of stellar irradiation it receives is still low, and could let the presence of liquid water on the planet’south surface, provided it has a sufficient atmosphere,” Pozuelos said. “This is because the star LP 890-9 is well-nigh 6.v times smaller than the Sun and has a surface temperature one-half that of our star.”
NASA’s Transiting Exoplanet Survey Satellite (TESS) searches for exoplanets orbiting nearby stars by monitoring light levels of thousands of stars. New planets are discovered when a planet passes in front of 1 of those stars, causing the light being monitored to dim.
ULiège scientists then follow upwards NASA’southward findings with ground-based telescopes to confirm and narrate the planets.
