Alpha Centauri B May Shed Light On Our Own Sun’s Anomalies
2013-02-20 12:52:10

Michael Harper for redOrbit.com — Your Universe Online As it turns out, studying our Sun can be rather difficult. It´s not the distance so much that keeps scientists guessing — although that certainly doesn´t help. The Sun´s intense heat also keeps scientists at bay, leaving them to make some of their observations and predictions based purely on context and far away measurements. One thing astronomers have been able to observe is a significant difference in...

Comet ISON To Put On Spectacular Show On Thanksgiving
2013-02-06 13:08:48

Alan McStravick for redOrbit.com - Your Universe Online Kislovodsk, literally translated, means “sour water.” It was in this town, named for the sour water in the springs that surround it, that Russian astronomers Vitali Nevksi and Artyom Novichonok made a very sweet discovery in September of last year. Officially, the comet they discovered was named C/2012 S1, but since the two astronomers were using the International Scientific Optical Network´s (ISON) 15.7-inch...

Solar Energy 101 - How Does It Work
2012-11-25 10:03:53

Alan McStravick for redOrbit.com - Your Universe Online The most abundant form of energy ever known has always been there. Through the course of human history, the Sun has offered, without cost, its light and heat for the benefit of every living organism on this rock we call Earth. The Sun is responsible for helping plants to grow, affecting temperatures in differing regions and producing winds. Our ability to harness these energies could help us to realize a future that is devoid of...

Proba-2 Veiwed Three Solar Eclipses Last Night
2012-11-14 11:22:33

[ Watch The Video ( 1 ) ]   [ Watch The Video ( 2 ) ] ESA ESA´s Sun-watching Proba-2 satellite experienced three partial solar eclipses last night while lucky observers watching from northern Australia were treated to a total solar eclipse. During a total solar eclipse, the Moon moves in front of the Sun as seen from Earth, their alignment and separation such that the much closer Moon appears large enough to block out the light from the much more distant Sun....

Are You Ready For A Total Solar Eclipse?
2012-11-13 10:24:35

ESA Tomorrow´s total solar eclipse will only be visible in its entirety to ground-based observers watching from northern Australia, but ESA´s Sun-watching Proba-2 satellite will have a ringside seat from its orbit around Earth. During a total solar eclipse the Moon moves in front of the Sun as seen from Earth, their separation and alignment such that the Moon appears large enough to temporarily block out the Sun´s light. An eerie light is cast over ground observers as...

Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...

Solar System
2012-10-22 06:09:41

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...

Solar Eclipse -- A solar eclipse occurs when Sun, Moon and Earth are on a single line, the Moon being in the middle. Seen from the Earth, the Moon is in front of the Sun and thus part or all of the light of the Sun is hidden by the Moon. Thus it may seem that a piece has been taken out of the Sun, or that it has suddenly disappeared. There are three types of solar eclipses: -- A partial solar eclipse: Only part of the Sun and the Moon overlap -- A total solar eclipse: All of the Sun...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
