NASA will host a news teleconference at 2 p.m. EDT Thursday, Aug. 15, to discuss the status of the agency's Kepler Space Telescope. Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, the region around a star in which the surface temperature of an orbiting planet might be suitable for liquid water. Launched in 2009, Kepler has discovered planets and planet candidates with a wide range of sizes and orbital distances and helped scientists...

Series Of Striking On-sky Images Taken By FLAMINGOS-2 Released Today
2013-08-09 07:57:15

Gemini Observatory Gemini Observatory’s latest tool for astronomers, a second-generation infrared instrument called FLAMINGOS-2, has “traveled a long road” to begin science observations for the Gemini scientific community. Recent images taken by FLAMINGOS-2 during its last commissioning phase dramatically illustrate that the instrument was worth the wait for astronomers around the world who are anxious to begin using it. “It’s already one of our most requested instruments at...

Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light. Based on the length of the transit, the amount of light that is blocked, and other factors, astronomers can infer a lot of information about the planet. Additionally, researchers will find planets by...

New Explorer Mission Chooses The 'Goldilocks Orbit'
2013-08-01 08:05:06

NASA Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it's not too close to Earth and her Moon, and it's not too far. In fact, it's just right. And as a result of this never-before-used orbit -- advanced and fine-tuned by NASA engineers and other members of the Transiting Exoplanet Survey Satellite (TESS) team -- the Explorer mission led by Ricker will be perfectly positioned to map the locations of more than 500 transiting exoplanets, extrasolar planets...

Pulsating Star Observations Shed New Light On Planetary Systems

April Flowers for redOrbit.com - Your Universe Online An international team of scientists, including physicists at New York University, Princeton University and the Max Planck Institute for Solar System Research, has devised a method for measuring the internal properties of a star that offers more accurate assessments of the star's orbiting planets. The team examined a star approximately 92 light-years away and almost 20 percent more massive than our Sun, called HD 52265. Scientists...

Chandra Eyes An Eclipsing Planet
2013-07-30 04:21:13

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time. A team writing in The Astrophysical Journal said they used the X-ray observatory to detect the exoplanet passing in front of its parent star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led...

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 Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
