Five Alien Worlds With Water Detected By Hubble Space Telescope
2013-12-03 14:19:52

[ Watch the Video: Water That's Out Of This World Detected By Hubble ] Lee Rannals for redOrbit.com - Your Universe Online NASA said its Hubble Space Telescope has detected subtle traces of water in the atmospheres of five distant alien worlds. Two teams of scientists have discovered faint signatures of water in the atmospheres of five exoplanets. This is the first study to conclusively measure and compare the profiles and intensities of these signatures on multiple worlds. "We're...

WASHINGTON, Dec. 3, 2013 /PRNewswire-USNewswire/ -- Using the powerful­ eye of NASA's Hubble Space Telescope, two teams of scientists have found faint signatures of water in the atmospheres of five distant planets. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The presence of atmospheric water was reported previously on a few exoplanets orbiting stars beyond our solar system, but this is the first study to conclusively measure and compare the profiles and...

Using Talk Radio To Track Space Debris
2013-12-02 12:42:54

[ Watch the Video: Listening Up For Space Debris ] Lee Rannals for redOrbit.com - Your Universe Online Top-40 mixes being played over the FM airwaves are helping scientists locate space junk orbiting around our planet. Australian astronomers are using pop songs, talk radio and the Murchison Widefield Array (MWA) to help prevent catastrophic space junk collisions. As radio waves bounce around, they deflect off thousands of objects orbiting the Earth, which the team is able to take...

How Many Habitable Exoplanets Exist
2013-11-26 13:17:30

John P. Millis, PhD for redOrbit.com - Your Universe Online In the last decade, exoplanet scientists have been finding new worlds at a brisk pace. But as the number of planetary bodies in our galaxy rises, questions about how many of these may, in fact, be habitable have been reaching a crescendo. The debate centers on the criteria for what it takes for a planet to be considered habitable. It seems the presence of liquid water on the surface is necessary, though some researchers are now...

NASA Vespr Rocket To Study Venus Atmosphere
2013-11-26 11:12:52

[ Watch the Video: NASA Sounding Rocket To Have A Look At Venus ] Brett Smith for redOrbit.com - Your Universe Online A NASA rocket being sent up to study the atmosphere of Venus is slated for launch on Monday; just seven days after the space agency launched a probe to study the Martian atmosphere. While the Mars Atmosphere and Volatile Evolution (MAVEN) mission launched from Cape Canaveral Air Force Station in Florida, the Venus Spectral Rocket (VeSpR) lifted off from White...

In The Hunt For Habitable Planets, A New Model May Be Key
2013-11-14 13:54:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers using new theoretical models have created a new method to simplify the search for Earth-like planets. The new models help rule out the possibility of Earth-like conditions on certain planets outside of our solar system. Yann Alibert, of the Center for Space and Habitability (CSH) at the University of Bern, and colleagues based the study on the mass and radius of a planet, helping to determine criteria that exclude the...

Dawn Mission Data Offers New Evidence On Vesta Asteroid's History
2013-11-07 15:32:00

Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the journal Nature rewrites the history of the giant asteroid Vesta, which was recently visited by NASA’s Dawn mission. It was during the Dawn mission that the spacecraft used its visible and infrared mapping spectrometer instrument to map out the surface of the asteroid, leading scientists to the belief that Vesta’s formation followed the script that rocky planets followed, where the mineral olivine should...

WASHINGTON, Nov. 4, 2013 /PRNewswire-USNewswire/ -- Scientists from around the world are gathered this week at NASA's Ames Research Center in Moffett Field, Calif., for the second Kepler Science Conference, where they will discuss the latest findings resulting from the analysis of Kepler Space Telescope data. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Included in these findings is the discovery of 833 new candidate planets, which will be announced today by the...

Scientists Meet To Discuss 833 New Exoplanets
2013-11-04 16:21:02

Lee Rannals for redOrbit.com - Your Universe Online An international group of scientists are gathering for the second Kepler Science Conference this week at NASA’s Ames Research Center in Moffett Field, California. Researchers will be discussing the latest findings from the Kepler Space Telescope data, which includes the discovery of 833 new candidate planets. Ten of the new exoplanets are less than twice the size of Earth and orbit in the habitable zone. New Kepler data shows that...

Explanet Same Size As Earth
2013-10-30 16:15:10

Brett Smith for redOrbit.com - Your Universe Online In August, an international team of researchers announced the discovery of a planet outside our solar system - also referred to as an exoplanet - that orbits its star in just 8.5 hours and is roughly the same size as Earth. Now, the same research team members that found the planet, dubbed Kepler 78b, have made another startling discovery: the planet’s mass is roughly the same as our own. "This planet is a complete mystery," said...

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...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

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...
