Explainer: Indian scientists discover exoplanet 600 light years from Earth

The second red dwarf star that was detected with a new planetary system is K2-240, and this particular star features two large planets that are double the size of Earth. Now, India has joined the group of countries that have discovered planets around stars. The host star is about 600 light years away from the Earth.

"Although the atmospheric temperature of red dwarf stars, around which these planets revolve, is 3,450 and 3,800 Kelvin respectively, nearly half the temperature of our Sun", the researchers said.

Abramovich rejects offer to buy Chelsea
Abramovich has had problems with a United Kingdom visa and also shelved the plans for an expansion of Stamford Bridge recently. Last month's Sunday Times rich list valued Ratcliffe at £21.05bn, compared to Abramovich's £9.3bn valuation.

According to the definition, these are the planets which orbit a star outside the solar system. The discovery of the new planet was made by calculating the mass of the planet using the indigenously designed "PRL Advance Radial-velocity Abu-sky Search" (PARAS) spectrograph that is integrated with 1.2m Telescope at PRL's Gurushikhar Observatory in Mount Abu, India. It revolves around the star in about 19.5 days. It's a super-Neptune or sub-Saturn size, which is of 27X Earth's mass and 6X Earth's radius.

On the other hand, only a few such accurate and powerful spectrographs exist around the world, the majority of which being in the U.S. and Europe.

Also announced is that Microsoft has acquiredWe Happy Few's developer, Compulsion Games , in addition to several other developers. Ninja Theory was probably the surprise and it may lead to Xbox only sequels to Hellblade: Senua's Sacrifice and Devil May Cry.

Being that close, you might think that the planets would be unbearably hot but the scientists say that might not be the case. The PRL scientists observed the target over a time-baseline of 420 days (in about 1.5 years) using the PARAS spectrograph for probing the nature of the system.

It is being reported that when it comes to the temperature of the three planets that are the same size as Earth, this is where the similarity ends as they would nearly certainly have surface temperatures that are much higher than our planet owing to the intense radiation given by the red dwarf star they orbit. Ice, silicates and iron content make up 60 per cent to 70 per cent of the total mass. This is what they have so far discovered.

In terms of the relationships between the group of G-7 leaders, Trump called it "a flawless 10" on a scale between "zero and 10". May 9: Pompeo, now USA secretary of state, makes another visit to Pyongyang to prepare for the planned Trump-Kim summit.

While we're not expecting to travel to Earth-like planets anytime soon, scientists are still preoccupied with finding them, if only to see that we're potentially not alone in the universe. However, he said, radial velocity observations as made in this case "are not, in general, discovery observations but [a] look at already known planetary systems for a better understanding of their nature".
