NASA's Voyager 1 Continues On Its Journey
2012-09-10 05:20:46

redOrbit Staff & Wire Reports - Your Universe Online The journey of NASA's Voyager 1 spacecraft towards interstellar space continued over the weekend, and officials with the US space agency continue to monitor the 35-year-old probe's progress as it grows ever closer to becoming the first man-made instrument to ever leave the solar system. As redOrbit.com's own Lawrence LeBlond reported last week, it is difficult to know when the vehicle, which is currently 11 billion miles from the...

NASA Juno Spacecraft Successfully Completes First Thruster Burn For 2013 Earth Fly-By
2012-08-31 10:46:08

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Jupiter orbiter Juno successfully fired its engine Thursday as it prepares to make a crucial fly-by around Earth to give it the momentum it needs to shoot off toward the solar system´s largest planet. The firing of the main engine lasted just short of 30 minutes, and should give the spacecraft, which is currently about 300 million miles away, the push it needs to make the boomerang pass. The maneuver is the first...

Lee Rannals for redOrbit.com - Your Universe Online Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before. The Voyager 2 spacecraft, and its twin Voyager 1, are still hurtling through space, on a path that is sending them outside of our Solar System. "Even 35 years on, our rugged Voyager spacecraft are poised to make new discoveries as we eagerly await the signs that we've...

Why Is The Sun So Perfectly Round?
2012-08-17 07:40:10

April Flowers for redOrbit.com - Your Universe Online On a summer's day, the sun dominates the sky looking for all the world like a big, round ball of light. Round is exactly what it is, it turns out. It is nearly the roundest object ever measured, according to a study from the University of Hawaii's Institute for Astronomy. If you scaled the sun down to the size of a beach ball, it would be so round that the difference between the widest and narrowest diameters would be much less than...

Russia Considering Cooperation In JUICE Jupiter Mission
2012-07-25 05:25:46

Lee Rannals for redOrbit.com - Your Universe Online The Russian space agency is considering participating in a developing project to send a spacecraft to Jupiter. The European Space Agency (ESA) is starting-up the Jupiter Icy Moon Explorer (JUICE) project, and Russian scientists are considering the possibility of participating, according to a Voice Of Russia report. Lee Fletcher from JUICE´s Oxford University scientific group presented the objectives of the mission at the...

Cassini, Titan, Water, Saturn
2012-06-29 04:55:20

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers using data from NASA's Cassini spacecraft have revealed that Titan has a layer of liquid water under its ice shell. During their study, they saw a large amount of squeezing and stretching as the moon orbited Saturn. They determined that if Titan were composed entirely of stiff rock, the gravitational attraction of Saturn would cause bulges, or solid "tides," 3 feet of height. Cassini reveled that...

Exoplanet Gets Partially Evaporated By Host Star
2012-06-28 14:21:08

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star. Using the Hubble Space Telescope, astronomers saw exoplanet HD 189733b bathe in an intense X-ray radiation after its parent star gave off a violet flare. The team observed the planet with Hubble during early 2010 and late 2011, during which HD 189733b was silhouetting its...

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
