Water from a planet for the first time - Super-Earth

Astronomers have for the first time discovered that atmospheric water exists in an orbiting planet in a habitable zone around a distant star. The planet K2-18b, in its new discovery, is a place of trust in the journey of life. Over the next ten years, new space telescopes will be able to determine whether there are gases that can be produced by life components in the atmosphere of K2-18  said by Professor Giovanna Tinetti of the University College London, the lead scientist of the group.

The habitable zone is a region that is thought to be warm enough to begin melting water on the surface of a planet. The new planet is twice as large as the earth. In planetary classification, such planets are referred to as "Super-Earth", with a cooling temperature of 0 to 40 degrees Celsius, enough for liquid water to exist.

'K2-18b' is located 111 light-years from Earth, about 650 million miles. So it can't send a plane. Accordingly, the only solution is to look at the new telescopes that will be launched in the decade beginning in 2020 to see if there are any gases that can only be produced by living parts in the atmosphere.

What is Exoplanet?

• Planets beyond our solar system are called exoplanets.
• The first exoplanet was discovered in 1992. It was orbiting a neuron that emitted electromagnetic radiation.
• More than 4,000 such planets have been observed to date using several techniques.
• Most of them are giant planets, believed to be similar to Jupiter or Jupiter.
• Most of the giant planets have been orbited around their stars.

Between 2016 and 2017, the team behind the discovery studied the planets discovered by the Hubble Space Telescope. Researchers have determined some of the chemicals in their atmosphere by studying the changes in light as they orbit the planets around their suns. The light emitted by the planets is greatly altered by the composition of the atmosphere.

Molecular seals of water, a substance essential for life on Earth, have been identified only by 'K2-18b'. However, other astronomers are debating whether K2-18b is worth living. One analysis shows that planets with a mass of 1.5 times the mass of the Earth are much less likely to have a rocky surface. There is also the idea that the size and gravity of 'K2-18b' may be a hindrance to life.
