Latest the Sun Stories
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.
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.
ESA’s quartet of satellites studying Earth’s magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.
An international team of astronomers using NASA's Chandra X-ray Observatory has created a sweeping new survey of dying stars – or planetary nebula – in the neighborhood of the Sun.
New eco-friendly, solar heating hot water system provides a 27% reduction in water usage and 43% reduction in gas consumption. Dallas, Texas (PRWEB) September
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.
Solar panels located on the Union Square Greenmarket’s van will generate clean power for cooking demonstrations New York, NY (PRWEB) June 25, 2012
A loose star cluster located approximately 800 to 1,000 light years from Earth could be vital in helping experts not only to understand how stars like the Sun evolve, but also to help them in the search for Earth-like planets.
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.
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...
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 is...
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....
