Distant, Possibly Habitable Planet Spotted by Citizen Scientists

NASA  Goddard

The nearby exoplanet, HD 21749b, orbits a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit.

In May 2017, citizen scientists began discussing a particular planet candidate, but it had only two transits, or passes of the planet in front of its star.

The discovery was announced Monday at the 233rd meeting of the American Astronomical Society in Seattle.

"It's the coolest small planet that we know of around a star this bright", said Diana Dragomir, a postdoctoral researcher in the Massachusetts Institute for Technology's Kavli Institute for Astrophysics and Space Research. The most significant discovery of TESS is a planet that is nearly 23 times more than Earth regarding January.

"This planet has a greater density than Neptune, but it isn't rocky", Dr Dragomir said. However, the planet is believed to be dense with a lot of water and has a thick atmosphere.

The researchers have also detected evidence of another planet, smaller than the others, which could be the first Earth-sized discovery by Tess.

The space telescope launched previous year as the successor to NASA's long-running and very successful Kepler turned in three exoplanets in its first three months of observations.

What's even more exciting are hints the system holds a second candidate planet about the size of Earth that orbits the star every eight days. Among planets that orbit close to their stars, there's a curious dearth of worlds between about 1.5 and two times Earth's size. The star is very similar to our sun, both in mass and in size.

Trump to address Americans amid fears of national emergency
The White House moved to pre-empt the Democrats, telling reporters Monday that tax refunds would be paid despite the shutdown. Mulvaney, who took part in talks with Pence and congressional aides on Saturday, said technical requests bogged them down.

Its size is unusual for an exoplanet (the term for a planet that orbits a star outside our solar system). The new planet seems to orbit the smaller star, and it needs 3.1 days to do it.

The new world lies in a stellar system called K2-288, which includes two dim, cool M-type stars that are roughly 5.1 billion miles (8.2 billion kilometers) apart - about six times the distance between Saturn and the sun, according to the statement. It's so close to its sun that some of its rocky surface could be molten lava during daytime. NASA's latest planet-hunting mission, TESS, will be providing more light curves that are full of potential planets waiting to be found.

In the first TESS sector alone, observed between July 25 and August 22, 2018, the mission caught dozens of short-lived, or transient, events, including images of six supernovae in distant galaxies that were later seen by ground-based telescopes.

Stay tuned for more news from TESS!

NASA's Kepler space telescope is dead. In Kepler's K2 mode, which ran from 2014 to 2018, the spacecraft repositioned itself to point at a new patch of sky at the start of each three-month observing campaign. The satellite will cover virtually the entire sky by the end of its two-year prime mission.

In its first year of operation, it will map the 13 sectors that make up the southern sky. Bright stars allow for easier followup study through ground- and space-based telescopes.

If you think scientists aren't the most imaginative bunch when it comes to naming things, then think again because boffins over in the States think they may have discovered a 'super Earth'.

While impressive, it does not appear the planet has the attributes required to support life as a habitable world.
