[Astronomers have found the first ex-moon]
The satellite was found in the same way as exoplanets are found - for a short-term periodic weakening of the luminosity of the star, which occurs when the planet passes between the observer on Earth and the star. In the case of a satellite, the luminosity change graph looks more complicated: additional minima are added when the satellite is not obscured by the planet. Just such a complicated schedule telescope "Kepler" recorded for an exoplanet, which rotates around the sun-like star Kepler-1625 in 4 thousand light years from Earth. To verify Kepler's data, the scientists wrote an application for Hubble's machine time, which states that the next time the planet is traversed through the Kepler-1625 disk, it will be possible to register this fall. Before discovering the moon of the planet from Kepler-1625, scientists examined data on 283 other exoplanets discovered by Kepler.

This, of course, is wonderful and interesting, but so far we can not fly to the ex-moon.
In how many decades or centuries will such far flights become available to us?
wow , so nice
followed you
Thank you)
