NASA's TESCO Telescope Cooling Telescope works for less than a year, but it already resembles some impressive discoveries. After the announcement of the new "Hot Saturn" in March, NASA has just discovered that TESS has found its first planet in terms of the size of the Earth outside of our solar system.
TESS – meaning Transiting Exoplanet Survey Satellite – designed to detect Explicit features of the exoplanet that rotate around the stars it observes reveals tiny changes in brightness associated with the passage of the planet in front of them. This last observation is actually the tenth confirmed TESS planet, but it is the first, which is probably close to the Earth in its overall size. However, you certainly will not want to go there.
The planet Earth size, which is called HD 21
Year on the planet lasts less than eight days on Earth, indicating that it is incredibly close to the star. This tight link means that the HD 21749c is absolutely hot and researchers estimate that its surface is likely to be about 800 degrees Fahrenheit, or about 427 degrees Celsius.
The planet and its star are not very far away. The HD 21749 is believed to be about 53 light years away, which means it's possible to explore it and its hot planet even more in detail.
HD 21749c is not the place where ever we expect to find life as we know it, so that foreign hunters should look elsewhere, but the discovery of any planet outside of our solar system is undoubtedly interesting In the future, the new TESS exoplanet discovery is expected to continue, so it can not be long before NASA finds a world that is even more like ours.
