Circumstellar habitable zone

There are billions of exoplanets in the Milky Way galaxy, but how many of those are potentially habitable?

In their search for potentially habitable planets outside our solar system, astronomers looked for exoplanets similar to Terra. Scientists now have a new class of habitable exoplanets to look for: the Hycean planets.

The study looked at various factors that could presumably lead to a habitable environment

It is 20% larger than Earth and orbits around its star for 37 days

NASA has announced that its exoplanet-seeking satellite TESS has discovered a new planet the size of Earth that is within a habitable distance of its star and where there may be liquid water, BTA reported.

It will take two million years to reach K2-18b, a rocky planet orbiting in the habitable zone of red dwarf K2-18, according to Angelos Tsiaras of the University College London's Center for Space Exochemistry Data (CSED) and the leader of one of the research teams that last week detected water vapor in its atmosphere.

NASA scientists have discovered more than 20 planets beyond the solar system with Kepler telescope data, which could have life, according to Independent.

The discovery shows that the potentially inhabited worlds are more than we originally thought.

Two planets that orbit around a star like our own sun could support life, according to new research, reported The Independent.

Two potentially habitable “super-Earths” orbit a star just 12 light years away that is our nearest sun-like neighbour, scientists have discovered.

The worlds at the edges of Tau Ceti’s “habitable zone” belong to a solar system of four rocky planets similar in size to Earth.

Nasa has announced the discovery of 219 new suspected planets outside our solar system.

The figure includes 10 that are “rocky” like Earth and which exist in their solar system’s ‘Goldilocks zone’, neither too close to their star, and therefore too hot, nor too far away and too cold for liquid water to exist.

European astronomers report the detection of a new extrasolar world several times more massive than Earth. The newly found exoplanet, classified as a so-called “super-Earth,” is circling a nearby star designated GJ 625. The researchers detailed their finding in a paper published May 18
