Astronomers find a Waterworld Planet in the habitable zone

Extrasolar planet

In search of extrasolar planets, astronomers pursue a policy of following the water. Searching for planets that orbit with a star's circumsolar habitable zone where the conditions are warm so liquid water can flow on its surface

Covered with water

Water is the only solvent capable of supporting life and is also required by all life on Earth. Since the 1970s, scientists have speculated that a class of rocky planets in the Universe is covered with water

Ocean world

An exoplanet orbiting within its system, HZ, was recently discovered that could be completely covered in deep oceans. This Ocean water reveals things about the nature of habitability

International team

Charles Cadieux led the international team and joined fifty-five astronomers and astrophysicists from France, Canada, the U.S., Japan, Brazil, Spain, Hungary, Portugal, Switzerland, Germany, and Russia

Two M-type stars

The system comprises two M-type stars that each orbit very closely at 97 astronomical units or about two and a half times the distance between the Sun and Pluto

Follow-up observation

The exoplanets experienced a slight decrease in brightness every 11 days, from which they estimated that they had a diameter about 70% larger than Earth

Single point

TOI-1452's two stars appeared in a single light point because of their low brightness and proximity. PESTO's resolution is high enough to distinguish the two objects, so the image confirmed an exoplanet does orbit TOI-1452
