Star Cluster Could Help Astronomers Find Earth-Like Planets
2012-06-23 06:15:20

A loose star cluster located approximately 800 to 1,000 light years from Earth, detected by scientists more than 180 years ago but never analyzed in detail, 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. According to a June 22 press release, researchers from Penn State University and colleagues from the University of California, Santa Cruz (UCSC); Yale University; and the California...

ESA Missions Observe Transit Of Venus
2012-06-06 06:59:03

[ Watch the Video ] 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. ESA´s microsatellite Proba-2, situated in low-Earth orbit, tracked Venus as it moved across the solar disc over a period of nearly seven hours. Venus appears to wobble thanks to the slight up-down motion of Proba-2 and the...

Entertainment Industries Council´s Sun SafeTee® program and the AJGA Team up to Teach Junior Golfers to Block the Sun, Not the Fun! with Key Sun Protection Skills for Life, on the Course and Off! Reston, VA (PRWEB) May 23, 2012 The Entertainment Industries Council, Inc. (EIC), through its Sun SafeTee program, is leading the charge to give junior golfers the potentially life-saving information to protect them stroke after stroke. As part of its nationwide program to provide the golf...

Rogue Planets Sometimes Captured By Stars
2012-04-18 03:28:47

New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space. The nomad worlds, which were kicked out of the star systems in which they formed, occasionally find a new home with a different sun. This finding could explain the existence of some planets that orbit surprisingly far from their stars, and even the existence of a double-planet system. "Stars trade planets just like baseball teams trade players," said Hagai Perets of...

Solar Storm Threat Appears To Have Passed
2012-03-09 12:26:43

[ Watch the Solar Flare in Action Here and Here ] Two recent Coronal Mass Ejections (CMEs) -- massive bursts of solar wind produced by the Sun -- appear to have caused little or no damage to electrical systems, according to scientists. The CMEs were caught by NASA as they took off from the Sun, traveling faster than 1,300 miles per second. The first wave hit yesterday morning, March 8. The second hit late last night into early this morning. Joseph Kunches, a scientist with the...

Sun Delivered Curveball Of Powerful Radiation At Earth
2012-02-02 04:32:26

A potent follow-up solar flare, which occurred Friday (Jan. 27, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet. According to University of New Hampshire scientists currently studying and modeling various aspects of solar radiation, this was due to both the existing population of energetic particles launched by the...

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....
