During the 1240s, Richard Fishacre, a Dominican friar at Oxford University, used his knowledge of light and color to show ...

Researchers have created the first color key of sky-dwelling microbes to help detect signs of alien life in the clouds of ...

The search for alien life often sparks the imagination with images of extraterrestrial beings and strange worlds. However, a ...

This illustration shows HD 189733b, a huge gas giant that orbits very close to its host star HD 189733. The planet's atmosphere is scorching with a temperature of over 1000 degrees Celsius, and it ...

In 1990, Voyager 1 captured the most distant portrait of our planet ever taken, revealing that from beyond Pluto's orbit, Earth appears as nothing more than a "pale blue dot." In a new study, ...

A new way of comparing the color andintensity changes of light reflected off of Earth's surface to the flickersfrom exoplanets may help reveal the presence of oceans, continents and ?possibly ? life ...

Astronomers from Cornell have developed a practical model that they call an environmental color decoder. The new practical model is designed to find climate clues to help in the search for potentially ...

Scientists have identified, at this point, more than 900 exoplanets -- planets that exist outside our solar system, orbiting other stars. We know those planets are out there; but we know that, in ...

This sand dune, known as Dingo Gap, was crossed by Mars Curiosity in 2014. This image has been slightly 'white balanced' as opposed to being shown in true color, which enables the differences in the ...

Atmospheric characterization of directly imaged planets has thus far been limited to ground-based observations of young, self-luminous, Jovian planets. Near-term space- and ground- based facilities ...

A giant gaseous planet that's orbiting a star 63 light-years away is a deep cobalt blue that's reminiscent of Earth's color as seen from space, scientists say, marking the first time an exoplanet's ...
