About 70% of the Earths surface is covered with water. Why do we have day and night? When a half of the Earth is facing the sun its daytime. As the Earth turns and this half is away from the sun night is coming.
Where will so many people live? How will we feed them?Unless we diffuse this "population bomb", by the end of the century we will need several Earths to survive. But we can't have several Earths, and so we will face a future of increasing poverty, food shortages, conflict and ...

By applying the algorithm to PLATO's discoveries, it should be able to narrow down the many thousands of systems to the few that have a higher chance of supporting an Earth-like planet, allowing astronomers to find them more quickly and efficiently. "This is a significant step ...
planet. Potential patches of organic material can be detected from the camera data: the brightness of the light reflected from these areas increases noticeably with increasing wavelength. The spectrometer splits the light into many more wavelengths than the camera and can therefore prove or disprove ...
Stars have many features that can be measured by studying the light that they emit: temperature spectrum or wavelengths of light emitted brightness luminosity size (radius) mass movement (toward or away from us, rate of spin) And if you're studying stars, you'll want to have these terms in...
