In astronomy, when we talk about the 'habitable zone' around a star, what does it mainly refer to? A. The zone where there is no radiation. B. The zone where water can exist in liquid form. C. The zone where only plants can survive. D. The zone where the temperature is E. ...
In subject area: Physics and Astronomy A 'Habitable Zone' refers to the region around a star where a rocky planet could have the right temperature for liquid water to exist on its surface, making it a potential environment for life to thrive. ...
we know that all life on Earth needs liquid water, so we search for other worlds that have it. If a planet, or a moon, hasliquid water, we say it's in the habitable zone, or more cautiously, the potentially habitable zone.
Definition The circumstellar habitable zone (HZ) is defined as the annulus around amain sequencestar where a rocky planet similar to Earth in composition and mass with an atmosphere can support liquid water on its surface. The inner edge is defined (Kasting et al.1993) as the distance at wh...
Astronomy: Earth twin spotted in habitable zoneThe article reports that a team of astronomers led by Elisa Quintana of the SETI Institute in Mountain View, California discovered a planet that is a similar size to earth orbiting a cool, dim star at just the right distance for liquid water to...
NASA's TESS spacecraft spotted two super-Earth planets as they crossed the face of their star within its 'habitable zone.'

“By the classical definition, the habitable zone around red dwarfs must be 10 to 20 times closer-in than Earth is to the sun. Now we know these red dwarf stars generate a lot of X-ray and extreme ultraviolet emissions at the habitable zones of exoplanets through frequent flares and...
the concept of the habitable zone has been defined to focus the search for life on those planets most likely to be able to sustain liquid water on their surface for extended durations. This chapter addresses the need for such definition, the current state-of-the-art of models that are used...
If the signal corresponding to HD 40307 g is a genuine Doppler signal of planetary origin, this candidate planet might be capable of supporting liquid water on its surface according to the current definition of the liquid water habitable zone around a star and is not likely to suffer from ...
