Earth-like planets discovered, NASA Says

A team from PRL (Physical Research Laboratory) has discovered this planet.

The Indian Space Research Organisation (ISRO) has made great strides in recent years, setting new records for satellite launches and putting a probe into orbit around Mars - all for incredibly efficient prices.

Ahmedabad have discovered a sub-Saturn or super-Neptune size exoplanet. The detection also adds to a sparse catalogue of 22 other confirmed exoplanet systems that have a mass and radius in this range, ISRO said.

While the planet is orbiting a Sun-like star, it's also roughly more than seven times closer to its star than Earth is to the Sun, which means the temperature could be around 600 degrees Celsius and likely too hot and dry to support life. The name of the planet is EPIC 211945201b or K2-236b, while that of the host star is EPIC 211945201 or K2-236.

The surface temperature of the planet is around 600C as it is very close to the host star (7 times nearer than Earth-Sun distance). A PARAS is a special kind of spectrograph that has a 1.2m telescope to locate such space objects.

The atmospheric temperatures around red stars are 3,450 and 3,800 K respectively. Kepler is the first NASA mission capable of detecting Earth-size planets, using the transit method or tiny dips in the brightness of a star when a planet crosses in front of it. Ice, silicates and iron content make up 60 per cent to 70 per cent of the total mass.

On the other hand, only a few such accurate and powerful spectrographs exist around the world, the majority of which being in the USA and Europe. Spectroscopic observations with the ESPRESSO instrument, installed in the Very Large Telescope (VLT), of the European Southern Observatory (ESO), or with future spectrographs in the GTC or in new astronomical facilities, such as the ELT or the TMT, will be crucial to determine the masses, densities and physical properties of these planets.

There are only a handful of nations that have the capability to explore regions so far away, let alone discover entirely new planets. As this system is reported to feature three rocky planets that are the same size as Earth, astronomers are taking notice.
