Researchers find hidden stars that may make planets appear smaller than they actually are

Firstpost  

Researchers have found that hidden stars may make planets appear smaller than they actually are, complicating the search for Earth-like planets. A system of two closely orbiting stars may appear in images as a single point of light, even from sophisticated observatories such as NASA’s Kepler space telescope. “Our understanding of how many planets are small like Earth, and how many are big like Jupiter, may change as we gain more information about the stars they orbit,” said one of the study authors Elise Furlan of the Infrared Processing and Analysis Center at California Institute of Technology. In the new study, Furlan and Steve Howell at NASA’s Ames Research Center in California’s Silicon Valley focused on 50 planets in the Kepler observatory’s field of view whose masses and radii were previously estimated.

First image of 2 exoplanets orbiting a sun-like star released

CNN  

CNN — About 300 light-years away from us, two giant exoplanets are orbiting a young sun-like star. By observing this system, centered around a star similar to ours that’s known as TYC 8998-760-1, astronomers can better understand how the planets in our solar system formed and evolved around the sun. The telescope’s SPHERE instrument, or Spectro-Polarimetric High-contrast Exoplanet Research, can …

NASA's Hubble space telescope spots a planet orbiting two stars

India TV News  

Astronomers using NASA’s Hubble space telescope have discovered a planet orbiting two stars in a system located about 8,000 light-years away towards the centre of our galaxy. "The ground-based observations suggested two possible scenarios for the three-body system: a Saturn-mass planet orbiting a close binary star pair or a Saturn-mass and an Earth-mass planet orbiting a single star," said David …

Telescopes are nowhere near good enough to see features on planets orbiting stars other than the sun. These ones, by an artist at the European Space Agency, are of “hot Jupiters”—gassy giants that orbit their parent stars more closely than Mercury does the sun. The planets’ spectra were collected using the Hubble space telescope by David Sing, of Exeter University, …

By Ian Steadman, Wired UK The Kepler space telescope has spotted the most tightly packed exoplanet system yet, with five planets orbiting around the star KOI-500 within a fraction of the distance between Mercury and our Sun. The outer four planets exist in a kind of orbital resonance, which sees them return to a set formation every 191 days -- …

A group of astronomers has estimated that as many as one in four stars similar to the Sun could be orbited by Earth-size planets. A five-year observation of 166 stars within 80 light years of Earth, using the powerful Keck telescope in Hawaii, counted planets orbiting the stars, down to the smallest planets now detectable by telescopes. Although the smallest …
