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.
(The darkest planet discovered so far is the pitch-black exoplanet TrES 2B, or Kepler-1b, located about 750 light-years away, which absorbs more than 99 percent of the light that hits it.)
The Hubble Space Telescope has observed an exoplanet – or planet orbiting a distant star – that looks as black as fresh asphalt. The planet is called WASP-12b, and it's one of a class of so-called hot Jupiters, gigantic, gaseous planets orbiting close to their host stars and thereby heated to extreme temperatures.
An alien world blacker than coal, the darkest planet known, has been discovered in the galaxy. The world in question is a giant the size of Jupiter known as TrES-2b.
The sky of Triton
Triton, Neptune's largest moon, has an atmosphere, but it is so thin that its sky is still black, possibly with some pale haze at the horizon.
At more temperate latitudes, the rings would look like a giant arch, crossing from one end of the sky to the other. These glittering rings would neither rise nor set, and would always appear in the exact same place in the sky. These cosmic landmarks would be visible both day and night.
The planets in our solar system are a veritable rainbow of colors. But what makes them take on all their various hues, and why does each one look so different? The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red.
So when we look at Mercury, regardless of whether it is from the surface or space, we get a clear view of its surface. And what we have seen is a dark gray, rocky planet.
On Saturn it occasionally rains diamonds.
The weather on HD 189733b is deadly. The winds, composed of silicate particles, blow up to 8,700 kilometres per hour (5,400 mph). Observations of this planet have also found evidence that it rains molten glass, horizontally.
Almost certainly yes. Unless it reflects absolutely no light at all, it's so close to the star that a lot of light is falling on it, so even if the albedo is, say, 0.01 (and it's hard to see how anything could be that dark), it would still reflect enough light to see.
The planet orbits a star that's a near twin to the Sun — it's the same size, mass, and temperature. It's about 750 light-years away. TrES-2b is a giant ball of gas. It's bigger and heavier than Jupiter, the giant of our own solar system.
Kepler has found the darkest known planet in universe–a Jupiter-sized exoplanet some 750 light-years away that is so black that it reflects just one percent of the light that reaches it. TrES-2b is so black that it's darker than coal, or any other planet or moon that we've yet discovered.
J1407b is the first exoplanet or brown dwarf discovered with a ring system by the transit method. A sequence of occultations (eclipses) of the star occurred over a 56-day period in 2007.
Well, at current market prices, 16 Psyche contain enough gold and other precious metals to be worth roughly $700 quintillion, which is enough to give every single human being on this planet a private fortune of nearly a hundred billion bucks.
Summary. In the Solar System, it would be possible for humans to walk on the terrestrial planets: Mercury, Venus, and Mars.
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts.
The Purple Planet is a ringed Earth-like planet located outside the Milky Way Galaxy. The planet is completely purple in color, including everything on its surface, and is home to a wide variety of intelligent extra-terrestrial life.
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.
Venus is entirely covered with a thick carbon dioxide atmosphere and sulphuric acid clouds which give it a light yellowish appearance.
The blue-green color results from the absorption of red light by methane gas in Uranus' deep, cold and remarkably clear atmosphere.
The normal hue of the sky during the daytime is a pinkish-red; however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown "butterscotch" color. On Mars, Rayleigh scattering is usually a very small effect.
But the sun itself is white. Sunlight spectrum in space as a function of wavelength.
