Researchers Discover First Earth-Sized Planet

A close by system greets the first Earth-akin planet found by Transiting Exoplanets Survey Satellite by NASA, as well as a lukewarm sub-Neptune-akin planet, as per a new document from a group of astronauts that comprises Carnegie’s Paul Butler, Johanna Teske, Jeff Crane, Steve Shectman, and Sharon Wang. Their study is posted in the Astrophysical Journal Letters.

“It is so thrilling that TESS, which blasted off just almost a year back, is already crucial in the planet-hunting sector,” claimed Teske, who is the paper’s second author. “The spacecraft studies the sky and we work with the TESS follow-up society to tag possibly interesting targets for extra surveillance with the help of ground-based instruments and telescopes.”

One such instrument, the Planet Finder Spectrograph (PFS) at Carnegie’s Las Campanas Observatory on the Magellan II telescope in Chile, was an important element of this effort. It assisted verify the planetary nature of the TESS signal, and to calculate the mass of the newly found sub-Neptune. The PFS operates with the help of a method dubbed as the radial velocity technique, which is presently the only method for astronauts to calculate the masses of separate planets.

On a related note, researchers seeking for hints of life further than our solar system encounter primary challenges, one of which is that there are billions of stars in the Milky Way alone to have a look. To narrow the hunt, they must understand: What types of stars are most probable to host habitable world?

A new research finds a specific class of stars dubbed as K stars, which are dimmer as compared to the Sun but brighter as compared to the faintest stars, might be specifically potential targets for hunting for hints of life. K stars has a very long life span, giving plenty of time for life to grow.
