It may be difficult to believe, but NASA’s Exoplanet has just reached 6,000 – and that is, about 30 years of hunting worlds outside our solar system. In fact, only three years ago, this number was 5,000. At least on the rated value, the discovery speed seems to be exponential – that is fine because theoretically we should have billions of worlds we could find.
“We get to another great study department – worlds, not just our imagination,” says narrator A NASA Video of the stage. “Find planets that can support life, find our cosmic neighbors and remind you that the universe still has worlds waiting for it to be found.”
The news was announced on Wednesday (September 17), which is serendipitically close to the anniversary when scientists confirmed the first exoplanet around the Sun -like star: 51 Pegings b. Discovered in 1995. October 6 Author Astronomers Michel Mayor and Didier Queeloz, 51 Pegasi B is a gas giant 0.64 times more massive than Jupiter, which is around 50 light -years from where you sit. (Obviously, the very first discovery of exoplanets decreased in 1992, but it was around a rotating neutron star or pulsar. And and Pulsars are quite wild. 51 Pegasi B was the first “normal” exoplanet to determine.) The right thing would be to complete this paragraph with a 6,000 exoplanean discovery equivalent to 51 peggs B, but unfortunately it is impossible.
This leads to the complexity of the NASA message. “The approved planets add to the number of scientists all over the world, so no planet is considered a 6000 record,” the agency said in a statement. “There are more than 8,000 additional candidate planets waiting for approval.”
Actually writing this article we are technically we are 6 007 exoplanets nasa The world of strangers; “New Discovery” showed by NASA Neptune -like world with the mass of approximately 16.35 land. NASA is also responsible for the majority of those exoplaneto finds containing the number of Tess (transit exoplanets survey satellite) At the age of 693, and Now the pension Kepler Space Telescope After finding more than 2600.
And while it can only be written with a few keys, every member of that 6 007 club is the whole world, similar to the planets of our solar system, which scientists have explored for centuries.
That calculation contains 2,035 -like worlds, according to exoplants of a similar size as our own solar system Neptune and Uranus. According to NASA, they usually have a “dominant atmosphere of hydrogen and helium with cores of rock and heavier metals”. (“Metals” do not necessarily mean metal elements. In astronomy, some confusion, it simply means heavier than hydrogen and helium elements).
There are 1,984 gas giants in the court (think about Jupiter’s relatives) and a 1,761 superstar-storage group should not be confused with Earth 2.0 candidates. Super land simply refers to exoplants, which are slightly larger than the Earth, but still lighter than the planets such as Neptune and Uranus.
NASA Exoplaneto Count also includes 700 “ground planets” or rocky worlds, and possibly the most charming seven “unknown” types.
Indeed, to further break those categories, you will need to stretch your brain to a place where you can imagine a two -face world semi -covered In Lava, Orb Made of a diamond This can discover your atmosphere, one Pulling through space more than 1 million miles per hour (1.6 million km / h) and physical After the devils;
“Each of the different types of planets we find a statement; “If we want to find out if we are alone in the universe, all this knowledge is necessary.”
However, the exoplanet hunting is mentioned in the phase of the phase of the agency’s video. “There is one we didn’t find – a planet like ours.”
At least not yet. ”
