Indian scientists discover exoplanet 600 light years away

A surprise announcement was just made today by the University of Oviedo and the Instituto de Astrofísica de Canarias (IAC) that researchers have discovered two brand new planetary systems, and one of these new systems is reported to contain three planets that are the exact size of Earth.

Artistic simulation of a planetary system composed by three rocky planets wiht the same size of the Earth. At least three rocky planets have been found, two of them being 1.1 times the radius of Earth, and the third planet being nearly the exact size. The star's effective temperature is estimated at 3,450 Kelvin degrees, which is almost one and a half times less than that of the sun. The planet is about 27 times the mass of Earth and six times the radius of Earth.

The scientists found that the host star is about 600 light years away from Earth and the planet goes around the star in 19.5 days.

Chennai: The scientists of PRL, Ahmedabad discovered a new planet (exoplanet) using PARAS spectrograph on Mt. Abu.

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. It has the name EPIC 211945201 (K2-236) and thus, the planet has been given the name EPIC 211945201B (K2-236B).

When Trump and Kim meet on the resort island of Sentosa on Tuesday they will be making history even before they start. But now, she said, property prices in Dandong were being driven up by speculators betting that trade would revive.

Tennessee woman arrested for transporting children in pet kennels
Cheeks told police that she placed the children in the kennels, but she made sure to check on them periodically. WATN said it attempted to contact Cheeks at her home over the weekend, but no one answered the door.

Rafael Nadal beats Dominic Thiem for 11th French Open title
Nadal also did not win the title in 2016, as he withdrew with an injury before his third-round match. Over the course of four games-from 4-5 in the first set to 0-3 in the second-Nadal won 20 points.

Researchers at the PRL believes that the discovery of such planets will help them to study the formation of sub-Neptune or sub-Saturn like planets. Ice, silicates and iron content make up 60 per cent to 70 per cent of the total mass.

The scientists observed the target over a time 420 days or about 1.5 years.

According to The Hindu, PARAS will be upgraded with a 2.5 m telescope, and it will be known as PARAS-2.

In the end, also in the news is the discovery of three Earth-sized planets, made by Spanish astronomers. But it does not necessarily mean that these planets are also habitable or have conditions necessary to support life. This discovery is the first of its type that occurred on the Indian territory, placing the Asian country on the very selective list of the countries that discovered far-distant worlds.
