An astronomy professor explains what exoplanets are, why he keeps looking for them and how Israel intercepts missiles “in ...

Astronomers have identified the most Earth like exoplanet yet, orbiting a sunlike star in the habitable zone 1,400 light years away. It is a snapshot of how far the search for life has come, and how ...

A new machine learning model has predicted that there are 44 Earth-like planets in other star systems in the Milky Way galaxy, with researchers from Switzerland claiming that the algorithm at the core ...

One of the worlds in the TRAPPIST-1 system, a mere 40 light-years away, just might be clad in a life-supporting atmosphere. In exciting new JWST observations, the Earth-sized exoplanet TRAPPIST-1e ...

Computer simulations suggest NASA’s Habitable Worlds Observatory could detect Earth-like exomoons around gas giant exoplanets through reflected starlight and lunar eclipses.

There may be another world lurking between the orbital lines of our solar system. Astronomers in Japan have published their theory of an “Earth-like planet,” dubbed Planet Nine, that’s hiding in plain ...

This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc. Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

Earth-like atmospheres require precise balances of nitrogen, oxygen, and CO₂, supported by long-term geological and biological processes. Most M-dwarf planets face atmospheric loss due to intense ...
