Astronomers find seven planets being 'fried' by their star

The Hindu  

In our solar system, little rocky Mercury is the planet orbiting closest to the sun, perpetually fried by solar radiation seven times more intense than what we experience on Earth. Astronomers using data obtained by NASA's now-retired Kepler space telescope have identified seven planets orbiting a star in our Milky Way galaxy, with all of them suffering the wrath of their star - radiant energy - even more brutally than Mercury. "All of the planets are 'fried' more intensely than any planet in our solar system," said astronomer Jack Lissauer of NASA's Ames Research Center in California, lead author of the study set to be published in the Journal of Planetary Science and currently posted on the arXiv research site. The smallest of its seven planets - 20% larger than Earth - orbits closest to the star, at a distance of a little more than 4% of the distance between our planet and the sun.

Nasa creates history with discovery of 6 new planets outside Solar System

India Today  

Nasa has announced the discovery of six new worlds, pushing the total number of confirmed planets beyond our solar system to 5,502. FINDING SIX NEW PLANETS The newly discovered exoplanets showcase a diverse range of characteristics. These discoveries employed various detection methods, including the radial velocity technique, which measures stellar wobble caused by orbiting planets, and the transit method, which …

Two potentially habitable planets discovered in our backyard. They are Earth-like

India Today  

For decades the field of astronomy has been centered around the question, is there another Earth out there? An international team of astronomers has found two planets that have Earth-like masses and are orbiting a red dwarf star. What's interesting is that it's not far from our solar system, just 16 light-years away, and both planets are in the habitable …

Understanding exoplanets: Unraveling the mysteries of planets that are hotter than stars

Firstpost  

Until the early 2000s, the only known planets were located in our own neighbourhood, the Solar System. They broadly form two categories: the small rocky planets in the inner Solar System and the cold gaseous planets located in the outer part. For example, data from the Kepler mission has shown that large, gaseous exoplanets can orbit very close to their …

7 planets orbiting TRAPPIST-1 may be made of similar stuff

India TV News  

The seven rocky planets orbiting the the red dwarf star TRAPPIST-1 have remarkably similar densities, which provides clues about their composition. The seven TRAPPIST-1 planets possess similar densities -- the values differ by no more than three per cent. The difference in density between the TRAPPIST-1 planets and Earth and Venus may seem small - about eight per cent - …

Astronomers discover exoplanet that behaves like long theorized Planet Nine

Hindustan Times  

The National Aeronautics and Space Administration and European Space Agency’s Hubble Space Telescope have helped astronomers and astronauts identify a bizarre exoplanet that behaves a lot like the long hypothesised ‘Planet Nine’. However, for scientists to pinpoint the Jupiter-like planet’s orbit, the Hubble Space Telescope was required to collect accurate measurements of its motion over 14 years. Hubble scientists also …

Scientists find two dozen ‘superhabitable’ exoplanets located over 100 light-years away

Firstpost  

Looking among the 4,500 known exoplanets, 24 planets were shortlisted that ranged from anywhere between five billion years and eight billion years old. In a study led by Washington State University9WSU) geobiologist Dirk Schulze-Makuch, two dozen exoplanets have been identified that are “super habitable” for living beings. They looked among the 4,500 known exoplanets and shortlisted those that range from …

Researchers have discovered the presence of a fifth planet in the family of four planets orbiting a distant star. The planet, named K2-138f, is one-tenth the distance that Earth is to the Sun and is one of the most closely packed planetary systems known to date. The planets, all rocky, range in size from 1.6 to 3.3 times the radius …
