NASA’s Kepler space telescope has seen a Jupiter-like spacecraft in recent years, even though the maker stopped work four years ago.
A global team of astrophysicists using NASA Kepler space telescope, which ceased operations in 2018, has identified an exoplanet like Jupiter that is 17,000 light -years away from Earth, the most distant exoplanet found by Kepler. of the exoplanetselected K2-2016-BLG-0005Lb, identified in data captured by Kepler in 2016. During its lifetime, Kepler saw over 2,700 hotels currently booked.
“Kepler was able to look inaccurately at the time or the sun, allowing us to accurately determine the size of the exoplanet and its orbital distance from its host star,” said Eamonn Kerins, an astronomer at the University of Manchester in the UK, spoken in a language. “It’s the equivalent of Jupiter’s twin in terms of its mass and its position from its sun, which is about 60% of our own sun,” he said.

The group, led by David Specht, a Ph.D. student at the University of Manchester, made good use of an event known as umekaumaha microlensing to see the exoplanet. With this event, predicted by Einstein’s theoryobjects in the sky can be seen and recorded when the light from a nearby star is trapped and thus amplified by the gravity of a nearby large object.
In the hopes of using flashlight from a distant star to see an exoplanet, the team spent three months of Kepler’s observation of the celestial sphere where this earth lies. .
“To see the effect on all objects requires the closest alignment between the foreground planetary system and a posterior star,” Kerins added in the same statement. “The number of stars to be found this way by Earth would be ten to one hundred million.”
The team then worked with Iain McDonald, an astronomer at the University of Manchester who developed a new search algorithm. Together, they can present up to five candidates in the database, with a clearer picture of an exoplanet. Other data on Earth recorded similar signals that Kepler saw on the exoplanet.
“The difference between Kepler and the observers on Earth is that we are able to triangulate around our line of sight in the Earth system,” Kerins said.
Aside from the joy of seeing an exoplanet with an unused instrument, the team’s work is well known because Kepler was not designed to detect exoplanets using this device. so so. It’s important to note, however, that in 2016, Kepler’s mission was expanded. In 2013, after two crashes of the second wheel, Kepler was expected to be used for a K2 “light pit” mission to see into space that could detect habitable exoplanets. This increase was approved in 2014 and the mission was increased before the expected deadline until the firewood ran out in October. 30, 2018.
“Kepler wasn’t designed to search for planets using microlensing so, in many ways, it’s amazing that it was done that way,” Kerins said, adding that the instruments could from things like NASA’s Nancy Grace Roman Space Telescope and the European Space Agency’s Euclid mission, it’s possible. .the use of microlensing to study exoplanets and could further research.
“Rome and Euclid, on the other hand, would be praised for this kind of work. They could have completed the census started by Kepler,” Kerins said. “We’re going to learn how our solar system works. The data will also allow us to test our understanding of how the stars work. This is just the beginning of something. an interesting chapter as we explore other worlds. “
