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."...

Kepler's Dozen - On The Hunt For Distant Worlds
2013-05-15 04:25:44

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Since its launch in 2009 the Kepler spacecraft has identified more than 2,500 planet candidates in our galaxy. Of these, several hundred have been confirmed as planets by ground based observatories. The observatory operates by monitoring stars in our galactic neighborhood and watching for tiny dips in the observed brightness. As the dips are repeated over time, researchers can deduce the presence of planets and even...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The field of exoplanet research — the study of planets outside of our solar system — has exploded in the last decade as new instruments have come online that have dramatically increased our ability to find new worlds. Perhaps the most important player in the game is the Kepler mission. It primarily works by analyzing stars in our galaxy and looking for tiny changes in a star´s brightness. As a planet...

Hunting For Alien World's From The Ground
2013-05-10 04:30:35

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In the search for life beyond Earth scientists face significant challenges. Given the great distances and faint signatures of the alien worlds that we have found, discovering which ones are even potentially habitable is difficult. While the first step is attempting to determine which worlds could maintain liquid water on their surfaces, an equally important factor is characterizing the atmosphere maintained above the...

What Really Makes A Habitable Planet?
2013-05-04 05:41:48

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The Holy Grail in the search for planets outside our solar system is finding one that could potentially support life. Traditionally, this means finding a planet with features similar to Earth, which is just the right distance from its host star that liquid water could be supported on the surface. Scientists believe the presence of liquid water on the surface is a necessary component for the proliferation of life. And a...

Uwingu Kicking Off 'Adopt-A-Planet' Campaign
2013-05-02 17:53:25

Lee Rannals for redOrbit.com — Your Universe Online Uwingu announced on Wednesday the launch of the world's first "Adopt-a-Planet" campaign, allowing the public an opportunity to adopt planets. The space company's new open-ended campaign allows the public to adopt exoplanets in astronomical databases through Uwingu's website. The campaign coincides with its other campaign aimed at naming a planet. Uwingu has asked participants to vote on names for exoplanets, which costs money....

Two New Exoplanets Confirmed
2013-04-30 05:08:49

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The newest addition to our planet-hunting arsenal, the HARPS spectrograph, has characterized two new worlds. Planets KOI-200 b and KOI-889 b are Jupiter-like planets that orbit very close to their host stars. With periods of less than 10 days, the so-called “Hot Jupiters” were originally detected using NASA´s Kepler spacecraft. This instrument has documented more than 800 new exoplanets, with thousands...

White Dwarf Search May Yield Habitable Planets
2013-04-25 05:25:40

April Flowers for redOrbit.com - Your Universe Online A dead star, known as a white dwarf, will eventually cool down and fade away because it has no energy source. A new study led by Professor Dan Maoz of Tel Aviv University's School of Physics and Astronomy suggests that white dwarfs can still support habitable planets. The team, which includes Prof. Avi Loeb, Director of Harvard University's Institute for Theory and Computation and a Sackler Professor by Special Appointment at TAU,...

SETI Scientist Will Lead NASA Next-Gen Successor To Kepler Mission
2013-04-21 05:19:51

redOrbit Staff & Wire Reports - Your Universe Online A SETI Institute scientist has been chosen to lead the design, development and operations of the data processing center for NASA´s next-generation successor to the Kepler Mission, the Mountain View, California-based organization announced on Friday. Jon M. Jenkins, a senior researcher at the Carl Sagan Center of the SETI Institute, will oversee operations of the Transiting Exoplanet Survey Satellite (TESS) Mission´s Data...

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

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...
