Tracking Russian Meteor Debris Field Offers Insight Into Future Events
2013-08-15 14:38:54

[WATCH VIDEO: Meteor Debris Around The World In Four Days] Brett Smith for redOrbit.com - Your Universe Online Using satellite data and computer models, NASA scientists were able to track and study the debris of the meteor that exploded over Chelyabinsk, Russia in February, giving them a better picture of how similar future events might affect the Earth’s atmosphere. Just after sunrise on February 15, a meteor measuring about 59 feet across and weighing over 12,000 tons exploded...

Venus Express Observes Strenghtening Winds On Second Planet From Sun
2013-06-18 15:11:30

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Venus Express spacecraft has revealed that the winds on the second planet from the Sun have been getting faster over the last six years. Venus holds a super-rotating atmosphere that is able to whip around the planet once every four Earth days. Scientists are able to monitor patterns in the long-term global wind speeds by tracking the movements of distinct features in the clouds of the planet....

NASA AIM Satellite Spots First Noctilucent Clouds Of 2013
2013-06-09 09:08:50

redOrbit Staff & Wire Reports — Your Universe Online Noctilucent clouds (NLCs), tenuous cloud-like phenomena that form every summer in the skies above the North Pole, are forming earlier than usual, NASA officials confirmed on Friday. According to the US space agency, NLCs are formed when “ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky.” These clouds, which...

Pollution, Storms And Climate: NASA Mission Investigates How They Interact
2013-06-07 11:09:55

April Flowers for redOrbit.com - Your Universe Online To investigate how air pollution and natural emissions, which are pushed high into the atmosphere by large storms, affect atmospheric composition and climate, NASA´s DC-8 and ER-2 science aircraft will take flight over the southern US this summer. This will be the most complex NASA airborne science campaign of the year drawing together coordinated observations from NASA satellites, aircraft and an array of ground sites. The...

NASA Curiosity Finds Evidence Of Atmosphere Thinning On Mars
2013-04-08 11:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Curiosity rover has been busy searching for signs that life may have once existed on the Red Planet. In the eight months since NASA dropped the rover on Mars, it has made significant progress in the hunt for water and life. In the latest round of evidence pertaining to Mars´ past, new measurements from Curiosity point towards the sky. These measurements, which consisted of analysis of Argon atoms in the...

Complex Chemistry Could Lead To Life On Titan
2013-04-03 19:20:52

Lee Rannals for redOrbit.com — Your Universe Online Scientists reported in the journal Nature Communications that complex organic chemistry could eventually lead to the building blocks of life on Saturn's moon Titan. Experiments at NASA's Jet Propulsion Laboratory have shown the same kind of biological chemistry on Earth's surface could also drive chemistry on Titan, even though the Saturn moon receives far less light from the sun and is much colder. "Titan is not a sleeping...

Is Mars Hot or Cold?
2013-02-08 14:49:48

Alan McStravick for redOrbit.com - Your Universe Online With all the attention being paid to Mars, we are learning something new about the red planet almost daily. Each new revelation is pretty heady information. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold. The early days of Earth was marked by a climate that was both warm and wet, and mirrors what Mars was like some 3.5 billion years ago....

Uranus Bizarre Weather Revealed
2012-10-17 12:09:48

[ Watch the Video: What is Uranus? ] Lee Rannals for redOrbit.com - Your Universe Online Uranus is coming into more focus than ever with a new technique developed by astronomers and applied at the Keck Observatory. Astronomers reported at the American Astronomical Society's Division for Planetary Sciences meeting that they have taken high-resolution infrared images of Uranus, revealing detail of the planet's bizarre weather. The latest details of the seventh planet from the Sun...

Venus Clouds Analyzed By Venus Express
2012-10-08 11:44:18

Lee Rannals for redOrbit.com - Your Universe Online An image released by the European Space Agency shows how not-alike Earth's twin planet really is. The Venus Express spacecraft snapped an image last December showing off clouds on Venus, and how they wrap the planet and its entirety. The spacecraft took the image 18,600 miles above the surface of Venus, showing the planet's 12 mile-thick carbon dioxide and sulphuric dioxide haze. The ultraviolet light image taken by Venus Express...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

Sky
2004-10-19 04:45:44

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
