The apparent path of the Sun across the sky. ... The path of the Sun across the celestial sphere is very close to that of the planets and the moon. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

... Bad Astronomy . ... This first Snack of the year 2000 (yes, I am one of those who says the Millennium begins in 2001) will talk a little about a wonderful event: a total lunar eclipse. On the evening of Thursday, January 20 (or the early morning Friday, January 21 if you lives east of England) the Moon will go undergo one of the best eclipses it can. ... The Moon stays in the Earth's shadow in a lunar eclipse longer the Earth stays in the Moon's shadow during a solar eclipse. ... 2008 Phil Plait. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

... 2009 July 18 . Planets, Great Wall, and Solar Eclipse . ... Explanation: This dramatic skyscape was recorded during the August 2008 total solar eclipse. ... Much anticipated , the 2009 July 22nd total solar eclipse will again be visible from China. Planets and bright stars will briefly appear in darkened daytime skies , though a total eclipse won't be seen from the Great Wall. ... About APOD | ...

Your viewing location is not important as long as it offers an unobstructed view of the south eastern sky.. ... You can use ?eclipse glasses? to view the Sun, these are made from aluminized Mylar filter material. ...

... The storm began quite unexpectedly. The strongest geomagnetic storm for the last seven months began on Earth almost precisely at the same time as the solar eclipse reached its maximal stage, the culmination of which occurred at GMT 02:35 (06:35 Moscow time). ... Oscillations of such amplitude in the magnetic field have not been observed since October, 11th of last year, which is more than seven months ago. ... We can only add that the magnetic storm lasted approximately 9 hours. ...

... The apparent path of the Sun across the sky. ... Like the planets, the Sun, too, moves around the zodiac, making one complete circuit each year. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

... On the morning of Thursday, 26 February, amid the Gal pagos Islands, the Sun will fade from view. Not the culmination of ancient prophecy, but none less mystical, Earth's small Moon will be executing a slow slide past the enormous Sun. ... And anyone living in southern North America, Central America, northern South America, or on islands and cruise ships in the Caribbean Sea will, weather permitting, have the opportunity to experience the wonder of a solar eclipse. ...

... Like the night sky on the Earth, the martian sky hosts a plethora of astronomical phenomena occurring around the clock in a neverending space opera played out for the benefit of robotic and future human observers alike. ... Moons . Mars has two moons, Phobos and Deimos . ... Under the same conditions, Deimos would be as bright as -5, somewhat brighter than the planet Venus appears in Earth's sky. ... The moons are also eclipsed by Mars itself (a situation analogous to lunar eclipses at the Earth). ...

... Jupiter is our Solar System?s very own superhero. The giant planet is two and a half times more massive than all the rest of the planets in our Solar System combined. And with great mass, comes great gravity. With the power of super-strong gravity, Jupiter plays a heroic role in our Solar System, protecting life on Earth. ... Unfortunately, we have found lots of solar systems with massive planets that lie close to their star, but not so many that lie far away, like Jupiter. ...

... The question which method of the detection of features in the test statistic is the most sensitive, is of considerable importance for all practical TSA applications. ... A power of the test statistic is the probability that is accepted for the given Y : . ... Then, all statistics based on models with 3 parameters have similar values of the test power: power spectrum, Scargle statistics, fit of a sinusoid, AOV(3) statistic and PDM(3) statistic with corrected probability distribution. ...

... September 5, 1998 . The Pulsar Powered Crab . Credit: J. Hester and P. Scowen ( ASU ), NASA . ... Using a stunning series of visible light images taken with the Hubble Space Telescope (HST) , astronomers have discovered spectacular pulsar powered motions within the Crab nebula. Highlights of this HST Crab "movie" show wisps of material moving away from the pulsar at half the speed of light, a scintillating halo, and an intense knot of emission dancing, sprite-like, above the pulsar's pole. ...
