Using data from NASA's Hubble and Spitzer Space Telescopes, astronomers found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a large fraction of the entire planet. The Hubble Space Telescope is a project of international cooperation between NASA and ESA.But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone.Earth isn't the only ocean world in our solar system. Water on other worlds exists in diverse forms on moons, dwarf planets, and even comets. Ice, water vapor in the atmosphere, and oceans on other worlds offer clues in the quest to discover life beyond our home planet.
Was the Earth covered in water : New research suggests ancient Earth was a water world, with little to no land in sight. And that could have major implications for the origin and evolution of life. While modern Earth's surface is about 70 percent water-covered, the new research indicates that our planet was a true ocean world some 3 billion years ago.
Did NASA find a water planet
Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth's diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.
Does Kepler 452b have water : Venus is too close to the Sun and is so hot that water would boil; Mars is too far away from the Sun and is so cold that water freezes. But the Earth and Kepler-452b are both at just the right distances from their stars so that water can be liquid, at a temperature between 0°C and 100°C.

Similar to Earth, Venus experiences a greenhouse effect, trapping heat from the sun and making the planet incredibly hot and inhospitable. The sun's heat breaks down carbon dioxide and carbon monoxide into oxygen atoms and other chemicals, filling Venus's atmosphere with oxygen.
Did NASA find a ocean world
An 'hycean' or a world of water under a hydrogen-rich atmosphere has been found on a sub-Neptune distant exoplanet. It contains an ocean of boiling water and its temperature could be as high as 100 degree Celsius. James Webb Space Telescope has discovered what could be a 'Waterworld with a boiling ocean'.No, NASA Doesn't Have a Live Megalodon Hidden in the Atlantic Ocean. Sure would be cool if they did, though. Troubled and troublesome depression-era filmmaker Carl Denham (Jack Black) would do just about anything to achieve fame and success.Whereas, according to the new study, water once covered at least close to 100% of Earth's surface, now it covers only 71%. There was also a previous study from last year that indicated that 3.2 billion years ago, Earth had much less surface land than it does now.
Originally Answered: Was the earth ever completely covered in water Yes, the earth was once covered with water. Over four billion years ago, a rock the size of Mars hit a larger rock. The collision created so much heat that the surface melted and the two bodies came together.
Is Neptune full of water : Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.
Could Kepler-452b have life : Astronomers say that the planet is in the “Goldilocks zone”, meaning that the distance of the planet from its star is just right, making it not too hot and not too cold for life to exist.
Can humans reach Kepler-452b
While Kepler-452b may appear a tantalizing target for the upcoming NASA missions, it is highly unlikely humans ever will step foot on Kepler-452b, thanks to the 1,400 light-years it will take them to reach there.
No planet in our solar system except Earth has air that any human can breathe regardless of their nationality. The only other rocky planets that have atmospheres at all are Venus and Mars and both of those atmospheres are more than 95% CO2.Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system …
What would a water world look like : According to calculations, the internal structure of a waterworld would consist of a metallic core with a radius of about 4000 kilometres. Then there would be a rocky mantle region extending to a height of 3500 kilometres above the core's surface, covered by a second mantle made of ice up to 5000 kilometres thick.
