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...

Super Earth Found In Habitable Zone Within Lyra Constellation
2013-04-18 13:50:16

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have discovered what could be considered the most Earth-like planet ever found outside our Solar System. The team used the Kepler Space Telescope to find Kepler 62f, a small rocky planet orbiting a Sun-like star in the Lyra constellation. The planet is about 1.4 times the size of Earth, and receives about half as much heat and radiation. Kepler 62f is one of two "super-Earth" planets discovered in the star Kepler...

IAU Speaks Out Against Planet Naming Site Uwingu
2013-04-15 12:01:28

Lee Rannals for redOrbit.com — Your Universe Online A few months ago, a new space website opened up its doors for the public to start selecting the names of other planets. Now, the International Astronomical Union (IAU) has stepped up and pointed out this isn't exactly the protocol for the scientific process of naming cosmic bodies. Over 800 planets have been detected outside the Solar System so far, and thousands more are still waiting to be confirmed. Recently, the website...

2013 Carl Sagan Fellowships Selected By NASA
2013-04-10 05:06:08

NASA's Jet Propulsion Laboratory NASA has selected five planet hunters to receive the 2013 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars. The primary goal of the fellowship program is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's...

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...

  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
