In the Zone: How Scientists Search for Habitable Planets

The habitable zone is the belt around a star where temperatures are ideal for liquid water -- an essential ingredient for life as we know it -- to pool on a planet''s surface. Earth lies within the habitable zone of our star, the sun. Beyond this zone, a planet would probably be too cold and frozen for life (though it''s possible life could be

Exoplanets

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system''s habitable zone. Hubble reveals that at least the inner five planets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune.

NASA''s Kepler Confirms Its First Planet In Habitable Zone

Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets. The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun.

ESA

The Sun''s habitable zone stretches from just beyond the orbit of Venus and just about encompasses Mars. The star in the famous TRAPPIST-1 system is a cool red dwarf and so its habitable zone is wrapped closely around it. The zone around giant hot stars lies much further out. Stars spend most of their time burning hydrogen in their cores.
