Golden zones abound: hundreds of millions of planets in the Milky Way could possibly support life

A new study suggests that a third of the planets orbiting dwarf stars common to the Milky Way could potentially support life. As in the story of Goldilocks and the Three Bears, one plate is too hot, the second is too cold and the third is just right

Prof. Omri Vandel will participate in two projects to find planets suitable for life

The research focuses on a relatively new topic - the programming of biological life in planets orbiting red dwarfs * To verify the hypothesis, the James Webb Space Telescope, and the Israeli Ultrasat Space Telescope when they are launched, will be directed to the planets discovered by Vandel and his colleagues

Iconography showing the habitable zone around the planet Teegarden in two conservative and optimistic scenarios, compared to our solar system and other planets discovered in their star's habitable zone. The scale is normalized to the size of our solar system. In practice the planets Teegarden b and Teegarden c are much closer to their sun. Illustration: C. Harman

The simulation aims to highlight the temperature differences that researchers hypothesize exist between the discovered planets. The inner two are too close and therefore would be too hot for liquid water, the middle three are in the sitting area where liquid water might be possible, while the outer two are too far away, and apparently, if there is water in them, they are frozen.

NASA's discovery of seven terrestrial planets in one system will spur a widespread hunt for similar systems

Astronomers using the Hubble Space Telescope and a trick of nature have confirmed the existence of a planet orbiting two stars in the OGLE-2007-BLG-349 system, located 8,000 light-years away toward the center of our galaxy. The observations are the first in which a three-body system has been discovered using the micro-cleaning technique

The Hubble Space Telescope discovered a planet orbiting two stars at the same time

The habitable zone near red dwarfs is very small, it is better to look for Earth-like planets elsewhere
