Astronomers Just Identified Another Important Aspect of Planets That Could Host Life

by Michelle Starr, ScienceAlert

We are, by now, pretty familiar with the concept of the Goldilocks zone. Also known as the habitable zone, it’s the distance from a star at which liquid water can be present on the surface on a planet – not so hot as to be vaporized, nor so cold as to be frozen.

These conditions matter because we count liquid water as a vital ingredient for life. But it’s not the only criterion that can help us to assess a planet’s potential habitability; according to new research based on decades of data, there are also Goldilocks stars.

Not all stars, you see, are built alike. Some are extremely hot and bright – such as the very young, blazing blue OB stars. Some are quite low in temperature, like red M-type dwarfs. These could perhaps be a good temperature, but the Goldilocks zone would be very close to the star, and red dwarfs tend to be turbulent, lashing their surrounding space with violent flares.
