Pluto is shown in a rainbow of colors that distinguish the different regions on the planet. The left side of the planet is mostly blue-green with purple swirls, while the right side ranges from a vibrant yellow-green at the top to a reddish orange toward the bottom."
Spectral analysis reveals Mercury's mineral makeup.
Different minerals appear in a rainbow of colors in this image of Mercury from NASA's MESSENGER spacecraft.
We see rainbows on earth when the sun's rays interact with water droplets, refracting light towards whoever is looking at it. To see a rainbow in outer space is quite rare given the certain specific atmospheric conditions that have to all come together.
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it's the temperature of a hot oven, and it's the planet's intense heat that causes it to glow.
The latest photos, captured with NASA's James Webb Space Telescope, show bands of blue and gray in the middle, with rainbow-colored hues at the planet's poles.

Bottom line: The Cassini spacecraft captured this image of multiple colors within the rings of Saturn. Turquoise-hued rings of Saturn contain particles of nearly pure water ice, while reddish rings contain ice particles with more contaminants.
It's a super Earth whose upper atmosphere reaches 500 degrees Fahrenheit (260 degrees Celcius), meaning it only gets hotter as you move down. It's barely a hair away from its star, completing a year in 1.6 Earth days. Life is incredibly unlikely to survive there.
NASA has taken a closer look at 55 Cancri e, an exoplanet that earned the nickname "diamond planet" due to research that suggests it has a carbon-rich composition.
Objects that reflect no sunlight are black. Consequently, HD 149026b might be the blackest known planet in the Universe, in addition to the hottest. The temperature of this dark and balmy planet was taken with NASA's Spitzer Space Telescope.
Why? Because the angle of the sun in relation to this southern coast of Western Australia is less than 42 degrees above the horizon (particularly in winter). The sun shines out of the north onto the rain that comes off the southern ocean... and because of the angle of the sun... you get Rainbows throughout the day!
The rainbow comprises a spectrum of light that appears in the sky as a result of light reflection, refraction, and dispersion in water droplets. The seven main colours we see in rainbow are red, orange, yellow, green, blue, indigo and violet. However, we never see colours like black, white or grey in rainbows.
This leaves only high-energy blue light to be reflected from our maroon veins. So, if you cut yourself in space, your blood would be a dark-red, maroon color.
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 yellow dwarf parent star every 1.75 days.
The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil, and ultimately descends from Proto-Indo European *erþō. From this it has cognates throughout the Germanic languages, including with Jörð, the name of the giantess of Norse myth.
Mercury has a dark gray, rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust.
Thus, Titan could potentially harbor environments with conditions suitable for life—meaning both life as we know it (in the subsurface ocean) and life as we don't know it (in the hydrocarbon liquid on the surface).
Super Saturn: A star with over 30 rings that are 200 times larger than Saturn.
Scientists have found evidence of cubic zirconia in Moon rocks, showing that the universe not only holds diamonds, but its own fire-safe knock-offs. Space could be absolutely shimmering with precious stones, though Mao emphasizes that they probably aren't quite like the ones in earthlings' jewelry boxes.
Phobetor, Draugr and Poltergeist
Some 2,300 light years from Earth lies the pulsar PSR B1257+12. It flashes 161 times per second and has been nicknamed “Lich” after an undead creature in western folklore. It is orbited by three rocky, terrestrial planets named Phobetor, Draugr and Poltergeist.
There is a lot of evidence for the planet – thought to be up to 20 times further out from the Sun than Neptune – but it may be impossible to see with current technology. The giant, hidden planet is thought to be 10 times larger than Earth and on an orbit that takes 10,000 or 20,000 years to go round the sun.
These doomed worlds were among the first and creepiest to be discovered as they orbit an undead star known as a pulsar. Pulsar planets like Poltergeist and its neighboring worlds, Phobetor and Draugr, are consumed with constant radiation from the star's core.
Venus' atmosphere mainly consists of carbon dioxide. It appears white because the clouds are mostly sulfuric acid, which is highly reflective.
Rings. Uranus has two sets of rings. The inner system of nine rings consists mostly of narrow, dark grey rings. There are two outer rings: the innermost one is reddish like dusty rings elsewhere in the solar system, and the outer ring is blue like Saturn's E ring.
This color is caused by the absence of light. The rays emitted by Saturn are of violet color.
