The hunt is on for terrestrial exoplanets in habitable zones, and some of the most promising candidates were discovered ...

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the ...

To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in ...

Scientists have long been intrigued by the surfaces of terrestrial bodies other than Earth that reveal deep similarities beneath their superficially differing volcanic and tectonic histories. A team ...

A new theory could explain the origin and properties of systems of rocky super-Earths and their relationship with the terrestrial planets of the solar system. A new theory for how rocky planets form ...

NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be ...

Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their atmospheres. Scientists at MIT, the University of Birmingham, and elsewhere ...

Artistic concept of the PDS 70 disk. JWST observations detected water in the inner disk, where normally terrestrial planets form. Two gas giant planets carved a wide gap in the disk made of gas and ...

Illustration of the planet 55 Cancri e, also called Janssen. The search for exoplanets—worlds that orbit stars other than our sun—may be focused on discovering another Earth, but it continues to ...

The first confirmed exoplanets were discovered in 1992 orbiting a pulsar, followed by the first discovery around a sun-like star in 1995. Currently, nearly 5,500 exoplanets in over 4,000 systems have ...

The International Astronomical Union (IAU) defines a planet as a celestial body orbiting the Sun, possessing sufficient mass for a nearly spherical shape, and having cleared its orbital neighborhood ...
