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 stunning new true-color mosaic of Mars is transforming how scientists—and the public—see the Red Planet. For decades, Mars has been portrayed in exaggerated reds and browns, often adjusted for ...

When Voyager 2 flew by Neptune in 1989, it sent back images that were processed to better reveal features like bands and a dark spot. But a new study says it's actually a greener planet.

During the 1240s, Richard Fishacre, a Dominican friar at Oxford University, used his knowledge of light and color to show that the stars and planets are made of the same elements found here on Earth.

detection of exoplanets with masses like Uranus and Neptune. Moreover, in the case of low-mass stars – like Proxima Centauri, cf. ESO PR 05/03 – HARPS will have the unique capability to detect big ...

In 1989, Voyager 2 became the first and only spacecraft to ever fly by Neptune, and images from that mission famously show a planet that's a deep azure color. But in reality, Neptune is far more of a ...
