NASA’s Kepler Space Telescope finds 219 new Planet Candidates

Mountain View, CA –  NASA’s Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new candidates, 10 of which are near-Earth size and orbiting in their star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet.

This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler’s first four years of data. It’s also the final catalog from the spacecraft’s view of the patch of sky in the Cygnus constellation.

NASA’s Kepler Space Telescope identifies details of TRAPPIST-1h orbits

Moffett Field, CA – Scientists using NASA’s Kepler space telescope identified a regular pattern in the orbits of the planets in the TRAPPIST-1 system that confirmed suspected details about the orbit of its outermost and least understood planet, TRAPPIST-1h.

TRAPPIST-1 is only eight percent the mass of our sun, making it a cooler and less luminous star. It’s home to seven Earth-size planets, three of which orbit in their star’s habitable zone — the range of distances from a star where liquid water could pool on the surface of a rocky planet. The system is located about 40 light-years away in the constellation of Aquarius. The star is estimated to be between 3 billion and 8 billion years old.

This artist’s concept shows TRAPPIST-1h, one of seven Earth-size planets in the TRAPPIST-1 planetary system. NASA’s Kepler spacecraft, operating in its K2 mission, obtained data that allowed scientists to determine that the orbital period of TRAPPIST-1h is 19 days. (NASA/JPL-Caltech)

NASA’s Kepler Space Telescope data used to create list of Planets that may be similar to Earth

Washington, D.C. – Using public data collected by NASA’s Kepler mission, astronomers have catalogued the planet candidates that may be similar to our third rock from the sun. The tabulation of candidates will help astronomers focus their research efforts in the search for life.

The analysis, led by Stephen Kane, an associate professor of physics and astronomy at San Francisco State University in California, highlights 20 candidates in the Kepler trove that are less than twice the size of Earth and orbit their star in the conservative habitable zone — the range of distances where liquid water could pool on the surface of an orbiting planet.

The artistic concept of Kepler-186f is the result of scientists and artists collaborating to imagine the appearance of these distant worlds. (NASA Ames/SETI Institute/JPL-Caltech)

NASA’s Kepler Space Telescope discovers biggest unnamed dwarf planet in our Solar System

May 12, 2016 |

Written by Michele Johnson

Moffett Field, CA – Dwarf planets tend to be a mysterious bunch. With the exception of Ceres, which resides in the main asteroid belt between Mars and Jupiter, all members of this class of minor planets in our solar system lurk in the depths beyond Neptune.

They are far from Earth – small and cold – which makes them difficult to observe, even with large telescopes. So it’s little wonder astronomers only discovered most of them in the past decade or so.

Pluto is a prime example of this elusiveness. Before NASA’s New Horizons spacecraft visited it in 2015, the largest of the dwarf planets had appeared as little more than a fuzzy blob, even to the keen-eyed Hubble Space Telescope.

New K2 results peg 2007 OR10 as the largest unnamed body in our solar system and the third largest of the current roster of about half a dozen dwarf planets. The dwarf planet Haumea has an oblong shape that is wider on its long axis than 2007 OR10, but its overall volume is smaller.

NASA’s Kepler Space Telescope observes a Supernova Shockwave as it reached the surface of a Star

March 23, 2016 |

Written by H. Pat Brennan of JPL and Michele Johnson of Ames

Pasadena, CA – The brilliant flash of an exploding star’s shockwave — what astronomers call the “shock breakout” — has been captured for the first time in visible light by NASA’s planet-hunter, the Kepler space telescope.

An international science team led by Peter Garnavich, an astrophysics professor at the University of Notre Dame in Indiana, analyzed light captured by Kepler every 30 minutes over a three-year period from 500 distant galaxies, searching some 50 trillion stars. They were hunting for signs of massive stellar death explosions known as supernovae.

The brilliant flash of an exploding star’s shockwave — what astronomers call the “shock breakout” — is illustrated in artist’s concept. (NASA Ames, STScI/G. Bacon)

NASA’s Kepler Space Telescope observations brings new Insight about Planets Kepler’s discovered

January 14, 2014 |

Written by Michele Johnson
NASA’s Ames Research Center

Moffett Field, CA – More than three-quarters of the planet candidates discovered by NASA’s Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth. Such planets dominate the galactic census but are not represented in our own solar system. Astronomers don’t know how they form or if they are made of rock, water or gas.

The Kepler team issued a report on four years of ground-based follow-up observations targeting Kepler’s exoplanet systems at the American Astronomical Society meeting in Washington. These observations confirm the numerous Kepler discoveries are indeed planets and yield mass measurements of these enigmatic worlds that vary between Earth and Neptune in size.

NASA’s Kepler Space Telescope data helps Astronomers discover Star Cluster with Transiting Planets

July 6, 2013 |

Moffett Field, CA – Approximately 3,000 light-years from Earth in the constellation Cygnus, Astronomers have found two planets smaller than three times the size of Earth orbiting sun-like stars in a crowded stellar cluster.

This finding demonstrates that small planets can form and persist in a densely packed cluster environment, and implies that the frequency and properties of planets in open clusters are consistent with those of planets around field stars not associated with clusters, like our sun, in the galaxy.

In the star cluster NGC 6811, astronomers have found two planets smaller than Neptune orbiting sun-like stars.

Amateur Astronomers use NASA’s Kepler Spacecraft data to discover Four Star Planet

Moffett Field, CA – The discovery of planets continues to expand beyond the domain of professional astronomers. A joint effort of amateur astronomers and scientists has led to the first reported case of a planet orbiting a double-star that, in turn, is orbited by a second distant pair of stars.

Aided by volunteer citizen scientists using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system. Only six planets are known to orbit two stars but none of these are orbited by a distant binary.

NASA’s Kepler Space Telescope finds Multiple Planets Orbiting Two Suns in the constellation Cygnus

Moffett Field, CA – Coming less than a year after the announcement of the first circumbinary planet, Kepler-16b, NASA’s Kepler mission has discovered multiple transiting planets orbiting two suns for the first time. This system, known as a circumbinary planetary system, is 4,900 light-years from Earth in the constellation Cygnus.

This discovery proves that more than one planet can form and persist in the stressful realm of a binary star and demonstrates the diversity of planetary systems in our galaxy.
