Will we know if TRAPPIST-1e has life?

The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, ...

In search for alien life, purple may be the new green

From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth, where conditions favored the evolution of organisms that perform oxygen-producing photosynthesis using ...

Gravitational waves may have made human life possible

Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research team headed by John R. ...

The mystery of fullerenes in space explained

A study from the Instituto de Astrofísica de Canarias (IAC) which combines laboratory chemistry with astrophysics, has shown for the first time that grains of dust formed by carbon and hydrogen in a highly disordered state, ...

Atmospheres in the TRAPPIST-1 system should be long gone

Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them are potentially habitable. ...

The improbable origins of life on Earth

We do not yet know how, where, or why life first appeared on our planet. Part of the difficulty is that "life" has no strict, universally agreed-upon definition.

Exploring the galactic habitable zone

Our planet sits in the habitable zone of our sun, the special place where water can be liquid on the surface of a world. But that's not the only thing special about us: we also sit in the galactic habitable zone, the region ...
