Discovering Venus: the most romantic planet in the Solar System.
The planet Saturn is probably the best known and most beautiful planet in the Solar System. Saturn's rings are far more extensive and more easily seen than those of any other planet.
Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings – made of chunks of ice and rock – but none are as spectacular or as complicated as Saturn's. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.
Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability.
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.
Mercury: The Forgotten Planet.
In 2006 the International Astronomical Union (IAU) demoted the much-loved Pluto from its position as the ninth planet from the Sun to one of five “dwarf planets.” The IAU had likely not anticipated the widespread outrage that followed the change in the solar system's lineup.
Considered a “benefic" planet, Venus has long been considered auspicious, which explains why the ancient Romans named this planet after the goddess of love, beauty, and money.
It's called Kepler-37b (O.K., so the name isn't so cute), it orbits a star 200 light-years away, and not only does it give us a new appreciation for how diverse so-called exoplanets can be, it also causes us to address — again — just how we define a planet in the first place.
Ariana Grande apparently likes giant planets. Specifically, Jupiter and Neptune.
Even from the Curiosity rover on Mars, the Earth shows up on photos as a tiny but delightful blue dot. Many people, including this stargazer, put Saturn in second place for the most beautiful planet in our solar system and certainly the best planet to gaze upon from Earth, even with a small telescope.
Jupiter, the Solar System's largest planet reflects many shades of white, red, orange, brown, and yellow. Changes in Jupiter's colors is subject to storms taking place in its atmosphere; these storms allow different chemicals to rise from areas closer to the planet's core to the tops of the clouds.
All gas giant planets (Jupiter, Saturn, Uranus and Neptune) in the Solar System have rings, while the terrestrial ones (Mercury, Venus, Earth and Mars) do not.
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.
Blue skies on a golden planet, and two of our solar system's greatest extremes – Saturn is a planet of contrasts and surprises.
“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.
The diamond rain phenomenon is believed by some scientists to take place on Uranus and Neptune in our solar system. It is thought it exists some 8,000 km below the surface of our ice giant neighbours, created from commonly found mixtures of hydrogen and carbon, squeezed together at incredible pressure.
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.
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
Evidence points to oceans on other planets and moons, even within our own solar system. But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface.
To conclude, any new human colonisation on another planet would be very difficult. The extreme weather conditions, the chemistry of the atmosphere and the vast amounts of resources needed to support human life all play into this.
