About 57 light years from Earth, astronomers have discovered a large new planet, colored a deep magenta. It's the second planet whose color has been directly observed by astronomers, the first being HD 189733b.
The Purple Planet is a gender-based Non-profit making, Non-governmental organization incorporated in the United Republic of Tanzania.
Purple is its own wavelength. Red and blue are actually at the opposite ends of the scale. So, that can't be done.
The Purple Planet is a ringed Earth-like planet located outside the Milky Way Galaxy.
It's a magenta-colored planet! 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.
Pluto's moons are listed here by orbital period, from shortest to longest. Charon, which is massive enough to have collapsed into a spheroid at some point in its history, is highlighted in light purple.
“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,” Nasa posted.
Green and purple stars do exist. The color of stars depends on their temperatures, and they emit radiation throughout the visible spectrum. But when a star emits peak radiation at a wavelength we define as green, it also emits radiation over the rest of the spectrum. Green is in the middle.
A "dead" star is one that has no more nuclear fusion going in it. When a star dies, it leaves some remnant behind. Depending on the mass of the star, the remnant can be a white dwarf, neutron star or a black hole. White dwarfs are what was once the core of a star.
The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun's rays, one that gave the organisms a violet hue.
Hence, it's possible that there was a stage of our planet's history that the researchers dubbed “Purple Earth”. That time would date somewhere between 2.4 to 3.5 billion years ago, prior to the Great Oxygenation Event, which was likely due to the rise chlorophyll-based photosynthesis.
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.
A composite map of Pluto (center), made from images taken by New Horizons' long-range (left) and color (right) cameras, shows its reddish brown color.
In the outer Solar System, well beyond the orbit of Neptune and Pluto, a ninth planet may be waiting to be discovered. This 'ghost planet', nicknamed Planet 9 or Planet X, has never been observed directly, but peculiar goings-on in the space beyond Neptune hint tantalisingly at its existence.
The surface of the planet is littered with brownish-red volcanic rocks. The bright red color you see in the Soviet Venera images of Venus have been brightened to show more surface detail. So, what color is Venus? Yellowish-white.
NASA's James Webb Space Telescope captured a stunning image of a purple spiral galaxy. According to British newspaper The Independent, an astronomer at the Cosmic Dawn Center in the Niels Bohr Institute at the University of Copenhagen, Gabriel Brammer, shared the photo on Twitter.
Dark stars are somewhat of a misnomer — they're not actually dark. In fact, they're likely some of the biggest and brightest stars in our universe. Yet no one has ever seen one.
The star R136a1 was initially measured at around 250 to 320 times the mass of our own Sun. The new estimate places it between 150 and 230 times the mass of the Sun.
When stars die, they become either black holes, neutron stars, or white dwarfs.
While it's not uncommon to spot purple skies during sunsets or sunrises, we can't help but wonder what causes them. Here, we discuss why our eyes see different colors in the sky and which factors impact those colors.
The largest, R136a1, is approximately 260 times the Sun's mass; the light from these hot, new, bright stars is predominantly blue, however. At first glance, it's surprising, since there are no pink stars, and the majority of young starlight is preferentially blue.
Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in “Star Wars.” The planet, Kepler-16b, is about 245 light years from Earth, is a gas giant, and is roughly the size of Saturn.
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. While the planet reflects no visible light, its heat causes it to radiate a little visible and a lot of infrared light.
It is probably not possible for a planet to be entirely liquid. This is because a planet needs to be 'self-gravitating' so that it holds its spherical shape under gravity. It thus requires a substantial amount of mass, which means the pressure and temperature in the inner regions are usually high.
A moonbow (sometimes known as a lunar rainbow) is an optical phenomenon caused when the light from the moon is refracted through water droplets in the air. The amount of light available even from the brightest full moon is far less than that produced by the sun so moonbows are incredibly faint and very rarely seen.
