Audi introduced its concept car Audi AI: Trail at the IAA 2019. The car is special because it combines futuristic design with autonomous driving, electric mobility.
International team of astronomers has discovered Earth like exoplanet. Nowadays it is very common the discoveries of exoplanets but scientists discovered two which one of these is special; Teegarden b is the most Earth like exoplanet.
The exoplanets orbiting Teegarden’s Star, named Teegarden b and c, were recently spotted at Spain’s Calar Alto observatory as part of the exoplanet-hunting CARMENES project, according to research published in the journal Astronomy & Astrophysics last week.
In the study, Teegarden b scored a 0.94 on what’s called the “Earth Similarity Index,” where a 1.0 would indicate a perfect Earth replica.
So the astronomers still should learn about the Teegarden exoplanets. They measured their mass and orbital distance, but they don’t exactly know how large they are.
“We are a bit hampered in what we can infer about these planets because we don’t know their radii,” Planetary Science Institute scientist Amy Barr Mlinar said. “But this is a very exciting find, and I hope we will get more observations of this system in the future.”
So if you don’t know what is exoplanet then we are happy to explain you.
An exoplanet or extrasolar planet is a planet outside the Solar System.
- The first evidence of an exoplanet was noted in 1917, but was not recognized as such.
- The first scientific detection of an exoplanet was in 1988; it was confirmed to be an exoplanet in 2012.
- As of 1 June 2019, there are 4,071 confirmed planets in 3,043 systems, with 659 systems having more than one planet.
