Purple bacteria that thrive in low-energy red or infrared light with a simpler method of photosynthesis could cover another planet, a new study says. Hotspots ranked Start the day smarter ☀️ ...

Another theory is that the planet was populated by ancient purple bacteria, whose descendants are found today in many lakes that do not require the same high salt concentration halophiles do ...

Life on alien worlds may not be green, like many organisms on Earth, but instead may be purple. Microbes with purple-pigments may be better suited to survive on distant planets.

Newly discovered? A purple planet! Actually, the color suggestion is just speculation based on the planet’s expected chemical composition. The planet, called WASP-104b, orbits 4 million km from its ...

Anyone who has seen an image of Earth from space can instantly recall our planet's fiercely blue oceans, resplendent green forests, and splotchy brown deserts. This work of art is our wondrous home.

It’s unable to measure the reflected light from the planet’s surface. “The difficulty is to translate what we're studying in the laboratory to astronomical measurements,” agrees DasSarma.

Earth's early life might have been purple, ... those reflection properties would be imprinted on that planet's reflected light spectrum," he said. Originally published on Live Science. ...

Retinal, today found in the plum-colored membrane of a photosynthetic microbe called halobacteria, absorbs green light and reflects back red and violet light, the combination of which appears purple.

The earliest life forms on Earth may have been purple. This theory could give us insight into what life on other planets might look like. CNN values your feedback ...
