Lee Rannals for redOrbit.com - Your Universe Online Astronomers have used NASA's Kepler to help spot another planetary system that has its planets neatly aligned, similar to our own Solar System. The study shows the trio of planets orbiting the star within one degree, relative to each other, and relative to the star's equator, showing a sense of geometry in its alignment. “In our solar system, the trajectory of the planets is parallel to the rotation of the sun, which shows...

Discoveries of new planets just keep coming and coming. Take, for instance, the 18 recently found by a team of astronomers led by scientists at the California Institute of Technology (Caltech). "It's the largest single announcement of planets in orbit around stars more massive than the sun, aside from the discoveries made by the Kepler mission," says John Johnson, assistant professor of astronomy at Caltech and the first author on the team's paper, which was published in the December...

Discovery opens door to new class of exoplanets A team led by a former postdoctoral researcher in MIT's Department of Earth, Atmospheric and Planetary Sciences and the MIT Kavli Institute for Astrophysics, recently measured the first-ever planetary atmosphere that is substantially enriched in carbon. The researchers found that the carbon-to-oxygen ratio of WASP-12b, an exoplanet about 1.4 times the mass of Jupiter and located about 1,200 light years away, is greater than one. As they report...

Orbiting Telescope Designed to Find Earth-Like Planets NASA's Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system. Kepler's high sensitivity to both small and large planets enabled the discovery of the exoplanets, named Kepler 4b, 5b, 6b, 7b and 8b. The discoveries were announced Monday, Jan. 4, by the members of the Kepler science team during a news briefing at...

When NASA's Kepler telescope rockets into the night sky on Friday, March 6, from Cape Canaveral Air Force Station in Florida, two University of California, Berkeley, astronomers - key members of the Kepler team - will be watching its fading contrail, hoping that the telescope will reveal Earth's and humanity's place in the universe. Kepler's main goal is to discover Earth-size planets outside our solar system with conditions conducive to life, but it also will tell us how common rocky planets...

New computer simulations put solar system in universal perspective Prevailing theoretical models attempting to explain the formation of the solar system have assumed it to be average in every way. Now a new study by Northwestern University astronomers, using recent data from the 300 exoplanets discovered orbiting other stars, turns that view on its head. The solar system, it turns out, is pretty special indeed. The study illustrates that if early conditions had been just slightly different,...

More than one-third of the giant planet systems recently detected outside our solar system may harbor Earth-like planets covered in deep global oceans that offer abundant potential for life, according to a new study by scientists associated with NASA's Astrobiology Institute. The study focuses on planetary systems that contain "Hot Jupiters": gas giant planets that orbit extremely close to their parent stars -- even closer than Mercury to our own sun. Hot Jupiters are believed to have...

NASA -- A JPL scientist and his team are preparing to bring to the study of extrasolar planets what George Lucas brought to "Star Wars": the prequel. Most extrasolar planets discovered so far are "hot Jupiters," gas giants orbiting close to their parent stars. But according to current theory, such planets should form much farther from their stars, where temperatures are cold enough for water and other volatiles to freeze. Finding these planets close to their stars is like finding snowmen...

EVANSTON, Ill. -- Except for the fact that we call it home, for centuries astronomers didn't have any particular reason to believe that our solar system was anything special in the universe. But, beginning with the discovery 10 years ago of the first planet outside our solar system, evidence suggests that, as far as planetary systems go, the solar system might be special indeed. Instead of the nice circular orbits our nine planets enjoy, most of the more than 160 extrasolar planets detected...

Counting down the top ten astrobiology stories for 2004 highlights the accomplishments of those exploring Mars, Saturn, comets, and planets beyond Pluto. Number three in this countdown was the remarkable progress in discovering new planets in other solar systems. Astrobiology Magazine -- Number three on the countdown of 2004 highlights was the remarkable progress made in discovering new worlds orbiting other stars. Planet hunting began in earnest only about 10 years ago, but today spans...

Word of the Day
  • 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.'
