Asteroid's Magnetic Mojo Loss Explained
2012-09-25 05:52:08

Lee Rannals for redOrbit.com - Your Universe Online Dr Christopher Russell presented a paper at the European Planetary Science Congress on Tuesday, explaining why one asteroid has lost its magnetic mojo. Asteroid 2201 Oljato orbits the Sun every 3.2 years, and during its lifetime, NASA's Pioneer Venus Orbiter has observed three passages of the space rock between Venus and the Sun. Each time the asteroid has been observed, Oljato had a marked increase in the region of unusual magnetic...

BepiColombo Gets Good Vibrations
2012-08-17 12:12:16

[ Watch The Video ( BepiColombo Vertical Vibration Test ) ] [ Watch The Video ( BepiColombo Vibrating Horizontally ) ] Mimicking the intense vibrations experienced by a satellite during launch, the engineering model of the BepiColombo mission to Mercury has been subjected to similar forces at ESA´s spacecraft test facilities. A major design issue for spacecraft arises from the intense environment experienced during launch, ranging from vigorous vibrations to deafening noise. It...

MESSENGER Marks 8th Anniversary Since Launch
2012-08-06 09:33:40

John Neumann for redOrbit.com - Your Universe Online Eight years ago this month, in 2004, the MESSENGER space probe was launched on a six-and-a-half year, 4.9-billion mile journey to be the first spacecraft to orbit the planet Mercury. The leisurely cruise included 15 trips around the Sun, a flyby of Earth, two flybys of Venus, and three flybys of Mercury. During its gravity assist swing-by of Earth, on August 2, 2005, Messenger´s cameras captured several hundred images of our...

Vaporizing Super-Earth Helps Characterize Exoplanet Attributes
2012-08-03 14:45:31

Lee Rannals for redOrbit.com - Your Universe Online Scientists collaborated recently to produce simulations of Earth-like planets being vaporized in order to help astronomers have a better grasp of what to look for in the atmosphere of candidate super-Earths. Super-Earths are rocky exoplanets that are more massive than Earth, but less massive than Neptune. Most of those that have been found so far orbit very close to their stars. Scientists writing in The Astrophysical Journal show...

Transit Of Venus Lived Up To Its Hype
2012-06-06 12:32:33

[ Watch the Video ] Lee Rannals for redOrbit.com Yesterday afternoon, the Earth was able to experience a moment in our solar system that will not be seen again until 2117, the Transit of Venus. Peering through a solar filter on my DSLR camera and a 200mm zoom lens made for a pretty good looking glass. As 4:06 mountain time started to approach, you could see a little black dot start to make its way between the Earth and the Sun. I missed the 2004 transit, but was able to see...

ESA Missions Observe Transit Of Venus
2012-06-06 06:59:03

[ Watch the Video ] Astronomers around the world looked to the sky last night and this morning to observe Venus as it passed across the face of the Sun for the last time this century. ESA´s Sun-watching space missions also tuned in for the solar spectacular. ESA´s microsatellite Proba-2, situated in low-Earth orbit, tracked Venus as it moved across the solar disc over a period of nearly seven hours. Venus appears to wobble thanks to the slight up-down motion of Proba-2 and the...

Image 1 - Final Countdown: Transit Of Venus Closing In
2012-06-05 14:29:11

Lee Rannals for redOrbit.com The Transit of Venus is upon us, so grab your sun viewing spectacles, head outside, and go get yourself a look at a cosmic event. For those kiddos that will be born today, or in the next few years, statistically speaking you will be able to rub this moment in most of their faces when they get older, because they will not get to see Venus pass by the Sun at any point in their lifetime. The next time the Transit of Venus will occur will be the year 2117....

Mysterious Arc Of Venus To Be Seen During Transit
2012-06-05 09:16:17

When Venus transits the sun on June 5th and 6th, an armada of spacecraft and ground-based telescopes will be on the lookout for something elusive and, until recently, unexpected: The Arc of Venus. "I was flabbergasted when I first saw it during the 2004 transit," recalls astronomy professor Jay Pasachoff of Williams College. "A bright, glowing rim appeared around the edge of Venus soon after it began to move into the sun." For a brief instant, the planet had turned into a "ring of...

Venus Transit Will Help RHESSI Improve Sun Measurements
2012-06-05 08:42:08

The RHESSI (Ramaty High Energy Solar Spectroscopic Imager) satellite focuses on the highest energy x-rays and gamma-rays produced by the sun, helping to observe solar flares of all shapes and sizes. The satellite is pointed toward the sun, and constantly in rotation, which provides a serendipitous bit of side research: by monitoring the limb of the sun on its four second rotation cycle, RHESSI´s Solar Aspect System (SAS) has produced ten years worth of precise measurements of the sun's...

Transit Of Venus Only A Day Away...Are You Prepared?
2012-06-04 10:00:17

[ Watch the Video ] Lee Rannals for redOrbit.com If you aren't looking up towards the sun tomorrow with the proper eye equipment, then a special moment is going to pass you by. The Transit of Venus is taking place on Tuesday, and it will not be seen again until 2117. The transits of Venus occur in pairs once every 100 years, so this upcoming transit is the last until the next generation gets their opportunity. Astronaut Don Pettit is up in the International Space Station armed...

The Pioneer Program is a series of American unmanned space missions designed for planetary exploration. The program included a number of missions, but the most well-known missions were Pioneer 10 and Pioneer 11. Both Pioneer 10 and 11 explored the outer planets and left our solar system. Both probes carry a gold plaque, depicting a man and a woman and information about the origin of the probes and their creators. The Pioneer probe was named by Stephen A. Saliga, who was chief designer of Air...

The Hard Clam (Mercenaria mercenaria), also known as the quahog, is a bivalve mollusk native to the eastern shores of North America, from Prince Edward Island to the Yucatan Peninsula. Older sources may give it the systematic name Venus mercenaria. It is one of many unrelated bivalves referred to as clams. Hard clams are quite common throughout New England, north into Canada, and all down the Eastern seaboard of the United States to Florida, but are particularly abundant between Cape Cod and...

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...

The Planet Venus is the second planet from the sun. It is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. Because its orbit lies between the sun and the orbit of the earth, Venus passes through phases like those of the moon, varying from a large bright crescent when the planet is near inferior conjunction (nearest the earth) to a smaller silvery disk when it is at superior conjunction (farthest from the earth). Since...

Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
