A New Set Of Directions For Exoplanet Hunting
2012-11-13 11:07:51

Lawrence LeBlond for redOrbit.com - Your Universe Online The search for planets around other stars might have gotten a little easier now that a Lowell Observatory astronomer and her colleagues have developed a set of directions, per se, to aid others in the hunt for exoplanets. Publishing their work in the journal Astrophysical Letters, Evgenya Shkolnik and her collaborators examined new and existing data from known stars and brown dwarfs that are less than 300 million years old, as...

Planets Likely Cause Of Star’s Disk Gap
2012-11-10 11:41:26

redOrbit Staff & Wire Reports — Your Universe Online A large gap discovered in the protoplanetary disk of a Sun-like star may have resulted from the birth of multiple planets, an international team of researchers claim in a new study. Jun Hashimoto of the National Astronomical Observatory of Japan (NAOJ), Ruobing Dong of Princeton University, and colleagues used state-of-the-art equipment to examine PDS 70 (an object discovered by the Pico dos Dias Observatory in Brazil in the...

First Planet Discovered In A Quadruple Star System Confirmed
2012-10-31 09:45:16

University of Notre Dame Justin Crepp, Freimann Assistant Professor of physics at the University of Notre Dame, provided the high-contrast imaging observations that confirmed the first extrasolar planet discovered in a quadruple star system. He is a co-author on a paper about the discovery, “Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System,” recently posted to the open-access arXiv.org, and submitted for publication to The Astrophysical Journal....

Super-Earths Will Be The Focus Of ESA Satellite Cheops
2012-10-22 07:10:07

Lawrence LeBlond for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced Friday October 19 that its new small Science Program mission, called Cheops (CHaracterizing ExOPlanets Satellite), will focus on nearby, bright stars that are already known to have planets in their orbit. The mission, expected to launch in 2017, will search for the telltale signs of transits as planets pass across the face of their host stars. To do this, Cheops will employ high-precision...

Search For Alien Life Reignited
2012-10-20 08:52:06

April Flowers for redOrbit.com — Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. In the past week, two new exoplanets have been confirmed; one by the Planet Hunters citizen science project that uses NASA's Kepler mission data, and the other by a European team. The existence of PH1 and the as-yet unnamed planet in Alpha Centauri will reignite the race...

WASHINGTON, Oct. 17, 2012 /PRNewswire-USNewswire/ -- The following is a statement about the European Southern Observatory's latest exoplanet discovery from NASA's Science Mission Directorate Associate Administrator, Dr. John Grunsfeld. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "We congratulate the European Southern Observatory team for making this exciting new exoplanet discovery. For astronomers, the search for exoplanets helps us understand our place in the universe...

Closest-Ever Exoplanet Discovered In The Alpha Centauri Star System
2012-10-17 14:08:24

Video 1 | Video 2 Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers have discovered a planet similar in mass to the Earth orbiting a star in the Alpha Centauri system – the nearest to Earth. Surpisingly, according to the astronomers, this planet which is just 4 light years away is also the lightest ever discovered around a star like our Sun. While the planet itself may be more similar in size and mass than Venus is to Earth, that´s where the good news...

Prestigious MacArthur Fellowship Received By Subaru Telescope Astronomer Olivier Guyon
2012-10-04 09:51:12

The John D. and Catherine T. MacArthur Foundation has chosen Subaru Telescope astronomer Dr. Olivier Guyon to receive a prestigious 2012 MacArthur Fellowship. He joins a diverse, elite group of 23 individuals nationwide selected for this annual honor. Awarded to "talented individuals in a variety of fields who have shown exceptional originality and dedication in their creative pursuits," the fellowships grant $500,000 to each recipient over a five-year period with no conditions placed on the...

Transit Of Venus Videos Unveiled

Lee Rannals for redOrbit.com — Your Universe Online [ Watch the Video: New Transit of Venus 2012 Movie ] [ Watch the Video: Transit of Venus 2012 From Svalbard and Canberra ] New movies of the transit of Venus that took place earlier this year clearly show the parallax effect that makes the event so important to scientists. Astronomers compressed six hours of observations and 5,000 individual images taken by optical and solar telescopes into a 40 second video. The...

Gemini Observatory Takes Sharpest Ground-Based Images Ever Of Pluto And Charon
2012-09-27 06:55:03

Lawrence LeBlond for redOrbit.com - Your Universe Online Pluto, the dwarf planet (ex-number-nine), and its larger companion Charon, recently posed for astronomers. Using the high-resolution Gemini North 8-meter telescope along with reconstructive speckle imaging, astronomers were able to capture the twin extrasolar planetary system, providing the sharpest ground-based images of the deep-space dwellers. The images prove that ground-based speckle imaging is a powerful tool for exoplanet...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
