Scientists from The University of Manchester are working on how to use the energy of the Sun to make fuels, which could help to solve the world's escalating energy crisis. Working with the Universities of East Anglia, York and Nottingham and using nanotechnology 100,000 times smaller than the thickness of a human hair, the researchers are working on harnessing the vast energy of the Sun to produce clean fuel. The scientists are presenting their research at the Royal Society's annual Summer...

ESA's Proba-2 small Sun-watcher was among the flotilla of satellites on watch as the Sun erupted spectacularly this week. After years of relative quietness, the Sun is waking up. Tuesday 7 June saw a medium-class M2.5 solar flare, associated with a proton storm, a coronal mass ejection that glanced past Earth on Thursday 9 June and an accompanying burst of radio energy. ESA's Proba-2 satellite was launched in November 2009, during the most inactive period of the solar cycle, but now the Sun...

In a new model of the early solar system, Jupiter is found to have been a youthful traveler, roaming as close to the Sun as where Mars is now and back out again before settling in its position as the fifth planet from our Sun. Scientists note that the planet's travels greatly influenced the solar system, altering the asteroid belt and making Mars smaller than it should have been. The model was developed by an international team of scientists and was published in the journal Nature on June...

Researchers at the University of Central Lancashire studied the largest solar flare recorded in nearly five years. The solar eruption in February was caused by five rotating sunspots working in concert, BBC News reports. Solar flares are eruptions on the surface of the sun which begin as concentrated magnetic fields and are visible as sunspots. As the magnetic fields build up, they twist and erupt, releasing vast amounts of heat, light and radiation."Twisting the Sun's magnetic field is like...

Astronomy & Astrophysics is publishing new observations of the giant planet around ÃŽ² Pictoris. Discovered in 2009, this planet, called ÃŽ² Pictoris b, has now been detected again with the NaCo instrument on the VLT. Astronomers find that the planet is moving around the star. They have also measured the mass and the effective temperature of ÃŽ² Pic b.Astronomy & Astrophysics publishes new high angular resolution observations of the...

Astrophysicists use computer simulations to gain new insights on star formation The first stars in the universe were not as solitary as previously thought. In fact, they could have formed alongside numerous companions when the gas disks that surrounded them broke up during formation, giving birth to sibling stars in the fragments. These are the findings of studies performed with the aid of computer simulations by researchers at Heidelberg University's Centre for Astronomy together with...

The first large-scale, physics-based space weather prediction model is transitioning from research into operation. Scientists affiliated with the National Science Foundation (NSF) Center for Integrated Space Weather Modeling (CISM) and the National Weather Service reported the news today at the annual American Meteorological Society (AMS) meeting in Seattle, Wash. The model will provide forecasters with a one-to-four day advance warning of high speed streams of solar plasma and Earth-directed...

A deep survey of more than 200,000 stars in our Milky Way galaxy has unveiled the sometimes petulant behavior of tiny red dwarf stars. These stars, which are smaller than the Sun, can unleash powerful eruptions called flares that may release the energy of more than 100 million atomic bombs. Red dwarfs are the most abundant stars in our universe and are presumably hosts to numerous planets. However, their erratic behavior could make life unpleasant, if not impossible, for many alien worlds....

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...

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....

  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
