Fifty might not sound like an impressive number, but these 50 exoplanets
will be the list of most promising transiting planets for further study, a list of planets that with follow-up observations will ultimately tell us a lot about the small-exoplanet
It is given a closer look before it is confirmed to be an exoplanet
- but the task is not an easy one as scientists must differentiate between signals from a candidate and signals from other spacecraft.
The upcoming launches of missions like NASA's James Webb Space Telescope and Transiting Exoplanet
Survey Satellite should further our understanding.
In the past, Barnes said, researchers tended to use that 12-hour estimation of Earth's rotation period to model exoplanet
behaviour, asking, for example, how long an Earthlike exoplanet
with a similar orbital spin might take to become tidally locked.
But by using pressure from light particles from the sun to stay oriented, the telescope has been refashioned for a second exoplanet
search project called K2.
Meanwhile, in a separate release, NASA confirmed that it used a technique known as microlensing to locate the exoplanet
Perhaps some were so disappointed by the false alarm in 2012, when another group claimed to have found an exoplanet
in the Alpha Centauri system, no one wanted to get their hopes up.
Most of the smaller and colder exoplanets
remain invisible for telescopes on earth.
We were able to observe the first, last quarters, new and full phases of this small exoplanet
," said Demory.
The Kepler space mission telescope also has spotted a few thousand exoplanet
candidates, of which more than 10% may turn out to be false-positives.
Dubbed a "mega-Earth," the exoplanet
Kepler-10c weighs 17 times as much as Earth and it circles a sunlike star in the constellation Draco.
They will not lead to an officially-recognised exoplanet
name, despite the price paid or the number of votes accrued.
