This page provides explanatory text for the dials shown on the Rice Current Solar Wind Conditions and Current Solar Wind Conditions (Dials Only) webpage. These dials use the last good received set of measurements from the Real Time Solar Wind package on the Advanced Composition Explorer (ACE) spacecraft. ...

... Bad Astronomy . ... Mad Science . ... What happens when something travel faster than the speed of light? ... The first way is to say that as far as we know, nothing can travel faster than light. ... What Einstein showed is that nothing can travel faster than the speed at which light can travel in a vacuum . ... This happens in our own atmosphere; particles from space can be moving just under the speed of light in a vacuum, but still be moving faster than light can travel in our atmosphere. ...

With this knowledge of orbits, we are ready to plan a trip to Mars. ... The spacecraft will already have the 107,000 kilometers per hour (66,500 miles per hour) speed of Earth, whereas Mars moves at only 86,900 kilometers per hour (53,900 miles per hour). ... A speed of about 42,000 kilometers per hour will be enough to escape the Earth's gravity and, when added to the Earth's orbital speed around the Sun, put the spacecraft on a Hohmann transfer orbit to the Red Planet. ... 1,570,000 . ...

... The solar wind - a few million tonnes of charged particles that leave the Sun every second - is continuously flowing past our planet at huge speeds (equivalent to travelling from London to New York in 5-15 seconds). ... Strangely enough, the fastest and most steady streams of solar wind originate from coronal holes. ... How such a large amount of matter escapes the Sun's huge gravity and reaches such high speeds (in the quietest solar regions!) is not yet known. ... View Slides . ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ...

... Energy . ... The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much, much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

... November 24, 1997 . Jet Near Light Speed . ... Jets of protons and electrons that shoot away from objects such as quasars and black holes appear to travel at speeds approaching this maximum speed, though. Such jets carry tremendous energy and can ram straight through interstellar material . In the above frame from a computer simulation , a jet traveling only 98 percent of light speed rams and mixes with interstellar material. ... About APOD > . ...

... The expansion is measured as a number called the Hubble Constant . ... Our value is about 20% lower than the one got with the Hubble Space Telescope in 1994," said Dr Jim Lovell, leader of the team that made the measurement. The Hubble Constant is named after American astronomer Edwin Hubble, who in the 1920s found that other galaxies were moving away from ours. ...
