Space Twisters Key To Solar Atmosphere's Heat
2012-06-28 09:20:11

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of researchers have discovered enormous tornadoes in space, more than a thousand miles wide, that could quite possibly be heating the surface of the Sun to more than a million degrees centigrade, a finding that has possible implications for clean Earth energy. These super tornadoes -- which are thousands of times larger and immensely more powerful than anything seen on Earth -- twist at speeds beyond 6,000...

Some Sun-like Stars Put Off Superflares
2012-05-17 13:32:04

New research shows that other sun-like stars in the universe can send off flares much larger than those seen on our sun. Solar flares are the result of broken magnetic-field loops as they pass through sunspots. As these loops become twisted and contorted, the flares occur, sending enormous amounts of charged particles, energy and radiation outward. So far, the largest solar flare ever measured on our sun happened on September 1, 1859, by British astronomer Richard Carrington. He simply...

The North Star, the Pole Star, the Guiding Star, Polaris: Its many names reflect the many centuries humans have gazed northward to it for guidance. However, recent studies have shown that the North Star is losing mass at a significant rate. Will Polaris, steadfast beacon for early sailors and adventurers alike, vanish from the night sky? Hilding Neilson of the Argelander Institute of Astronomy at the University of Bonn in Germany thinks that he and his colleagues have unlocked the answer...

Image 1 - Supernovae Could Have Had Impact On Life On Earth
2012-04-24 12:12:07

New research by a Danish physicist suggests that life might have been influenced by supernovae near the Solar System. When massive stars reach the end of their life, they explode as supernovae, which can be brighter than an entire galaxy of normal stars. The remnants of these events release vast numbers of high-energy charged particles known as galactic cosmic rays (GCR). If a supernova is close enough to our Solar System, the enhanced GCR levels can have direct impacts on the...

Georg Friedrich Julius Arthur von Auwers (September 12, 1838 "“ January 24, 1915) was a German astronomer born in Göttingen, Germany. He attended the University of Göttingen and worked at the University of Königsberg. Auwers specialized in astrometry, making very precise measurements of stellar positions and motions. He detected the companion stars of Sirius and Procyon from their effects on the main star's motion, before telescopes were powerful enough to visually observe them....

Charles Greeley Abbot (May 31, 1872 "“ December 17, 1973) was an American astrophysicist and astronomer born in Wilton, New Hampshire. He graduated from Phillips Academy in 1891 and MIT in 1894, with a degree in chemical physics. In 1895 Abbot was hired by Samuel Pierpont Langley as an assistant at the Smithsonian Astrophysical Observatory (SAO) despite his lack of experience in astronomy. Hired originally for his laboratory skills, Abbot became acting director of the SAO in 1896. When...

Triangulum Australe Constellation -- Triangulum Australe, the Southern Triangle, is completely visible in latitudes south of 20 degrees north from April through June. Its three brightest stars have been called the "Three Patriarchs", Abraham, Isaac and Jacob. It can easily be recognized by its shape, or asterism. This is one of the 12 southern constellations named by Johann Bayer in the early 1600's. The three bright stars in this constellation are so recognizable that they can be...

Serpens Constellation -- Serpens (the snake) is one of the 88 modern constellations, and was also one of the 48 listed by Ptolemy. Among the modern constellations it is unique in being split into two pieces, Serpens Caput (representing the head of the snake) to the west and Serpens Cauda (representing the tail) to the east. Between these two pieces lies the constellation of Ophiuchus, the serpent bearer. Notable features Since Serpens is regarded as being one constellation...

Scorpius Constellation -- Scorpius (the scorpion) is one of the constellations of the zodiac. In western astrology it is known as "Scorpio." It lies between Libra to the west and Sagittarius to the east. It is a large constellation located in the southern hemisphere near the center of the Milky Way. Notable features Scorpius contains many bright stars, including Antares (α Sco), Graffias (β1 Sco), Dschubba (δ Sco), Sargas (θ Sco), Shaula (λ Sco), Jabah (ν Sco),...
