New Planet Hunting Technique
2013-06-10 12:43:01

Lee Rannals for redOrbit.com - Your Universe Online Sponsored by the International Astronomical Union (AIU), a team of astronomers is working on a technique capable of detecting faint dust clouds around other stars where Earth-like planets could be hiding. This new technology could dramatically improve the odds of discovering planets with conditions suitable for life. "Current technology allows us to detect only the brightest clouds, those that are a few thousand times brighter than the...

Stars And Planets Larger Than Thought Kepler
2013-06-04 13:36:00

Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the Astrophysical Journal say they have found that many of the stars and planets discovered are larger than previously thought. The astronomers used the NOAO Kitt Peak National Observatory Mayall 4-meter telescope to observe candidate planets identified by the NASA Kepler Mission and found that most of the stars observed are larger than originally thought, and a quarter of them were 35 percent bigger....

Low-Budget Ground Telescope Pinpoints Gas Giant Exoplanet
2013-06-04 13:45:19

Lee Rannals for redOrbit.com — Your Universe Online Scientists announced during the American Astronomical Society´s (AAS) national meeting in Indianapolis this week that they have discovered a hot Saturn-like planet in another solar system 700 light-years away. The team used an inexpensive ground-based telescope to discover KELT-6b, which resides in the constellation Coma Berenices near Leo. This exoplanet has an orbit that transits its star every 7.8 days. Because of the...

Electrifying Exoplanets With Stellar Winds
2013-06-04 11:10:37

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own. Small, rocky worlds orbiting a couple of astronomical units from the host star, with the gas giant planets orbiting farther out. After all, much effort had been given to explaining how a solar system such as ours would form. Only, this is not what has been found. Many solar systems are constructed...

Least Massive Exoplanet Outside The Solar System Observed By ESO Telescope
2013-06-03 05:43:49

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) have imaged possibly the faintest exoplanet so far. The team reported in Astrophysical Journal Letters that they imaged a faint object moving near a bright star. The exoplanet has an estimated mass of four to five times that of Jupiter, which could potentially make it the least massive planet to be directly observed outside the Solar System....

White Dwarf Star Cooling Rates Updated By New Data
2013-05-29 16:00:35

Lee Rannals for redOrbit.com — Your Universe Online University of British Columbia (UBC) astronomers have determined that white dwarfs cool more slowly in the early stages of their life than models have previously predicted. White dwarfs are the dense, hot remnant cores of stars that have used up all of their fuel and lost their outer layers during the red giant phase. When these objects form, their surface temperatures are very hot, but cool over time as they radiate their...

Tiny Telescopes Ready To Study Sun's Future And The Origins Of Atoms
2013-05-29 05:17:17

Lee Rannals for redOrbit.com - Your Universe Online The smallest space telescope to ever hit the cosmos will soon start observing the largest stars in history. The BRIght Target Explorer (BRITE) telescopes will target the sky for the most luminous stars in our galaxy. Eventually, the two currently in orbit will be part of a "constellation" of telescopes in orbit that will monitor the sky regularly for years to come. Each BRITE satellite holds a small optical telescope feeding a CCD...

Scientists Has Plan To Revive Defunct Kepler Telescope
2013-05-16 14:29:36

Lee Rannals for redOrbit.com - Your Universe Online NASA announced yesterday that its Kepler space telescope is stuck in standby mode, but one professor is already coming up with ideas to try and revive the observatory. Scott Hubbard, a consulting professor of aeronautics and astronautics, helped guide the Kepler mission when he served as director of NASA Ames Research Center. He has devised a few plans for the space agency that could potentially help bring the planet-hunting spacecraft...

Kepler Goes Into Thruster-Controlled Safe Mode
2013-05-15 18:53:56

Lee Rannals for redOrbit.com — Your Universe Online NASA announced on Wednesday that its Kepler spacecraft was sitting in safe mode once again, possibly putting an end to its high-accuracy observations. Kepler went into a Thruster-Controlled Safe Mode earlier in May, and NASA said its spacecraft is sitting in the same position again. The space agency said the root cause of Kepler putting itself into safe mode is unknown, but the possible cause "appears to be an altitude error."...

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

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...
