Super-Earth among trio of planets and six supernovae detected by Tess mission
Three new planets and six supernovae outside our solar system have been observed by Nasas planet-hunting Tess mission in its first three months.
Since it started surveying the sky in July, the MIT-led Transiting Exoplanet Survey Satellite project has identified Pi Mensae b, a super-Earth that travels around its star every six days, and LHS 3844b, a rocky world with an orbit of only 11 hours.
The most recent discovery, an exoplanet named HD 21749b, has the longest orbital period at 36 days. It orbits a bright, nearby dwarf star about 53 light years away in the Reticulum constellation, and is thought to have a surface temperature of about 1,650C (3,000F). This is relatively cool considering its proximity to its star.
Diana Dragomir, a Hubble fellow at MITs Kavli Institute for Astrophysics and Space Research who led the discovery team, said: Its the coolest planet we know of around a star this bright. Its very hard to find small planets that orbit farther from their stars, and are therefore cooler. But here we were lucky, and can now study this one in more detail.

While on this planet..............there was this orange hair "guy" sitting behind a desk.............bloviating like a gas cloud, while NASA is going unfunded (Democrats passed bills to fund the government) and employees were furloughed....................
