Soon, our
@ESA_CHEOPS mission will start studying#exoplanets as they transit across the disc of their host star
Until then, enjoy this photo of the #Cheops satellite transiting in front of a bright star – as seen from Earth

#SolarOrbiter spacecraft will venture just 42 million km from the Sun – about as close as it is possible to go and still be able to image our fiery parent star without having its instruments melt.

What is Solar Orbiter?The mission will answer some of the biggest questions in solar science. What drives the solar wind and how does space weather impact the Earth?

From the intricate brightening pattern of this source, the astronomers realised that the celestial body acting as a 'cosmic magnifying lens' was a binary system: a pair of rather small stars, orbiting each other in less than three years

This unusual behaviour was caused by gravitational
#microlensing – an effect predicted by Einstein’s theory of general relativity, as the#gravity of massive objects (eg. a star) bends the fabric of spacetime in their vicinity & distorts the path of light from background sourcespic.twitter.com/Y0sp6CTp0lPrikaži ovu nitHvala.

The
@ESAGaia alert triggered follow-up observations made with 50+ telescopes worldwide

Astronomers kept an eye on the background star as it brightened up & declined 5 times, until the end of 2017

The brightening of the background star was first spotted in August 2016 by
@ESAGaia – which scans the sky on its mission to map 1 billion stars in our Milky Way galaxy – as part of@gaia_alerts, a programme that alerts astronomers to unusual brightness variations or new sources

A 500-day global observing campaign, spearheaded in 2016 by our
@ESAGaia mission, has provided unprecedented insights into a binary stellar system which caused an unusual brightening of an even more distant star
