This week’s viewer question comes from Young Silenter.
Two million people signed up on Facebook to go alien hunting at the highly classified US air force facility Area 51. Are they crazy or is there something to it? What would happen if we came into contact with aliens?
A Soyuz rocket carrying ESA's CHEOPS mission has taken off from Kourou. CHEOPS will investigate known exoplanets in more detail. This way we can learn more about their mass, density and perhaps even their atmosphere.
The CHEOPS satellite will study planets in nearby solar systems to measure their size and determine if they have an atmosphere. Scientists hope this could provide vital clues about the origins of our lives on Earth.
Between the deeply mystifying, intangible stuff — dark energy and dark matter — and the similarly complex, yet tangible findings — exoplanets — 2019's winners bring us ever closer to grasping our place in the universe.
