Discovery Points To 2 Different Classes Of Supernovae
2011-11-10 04:36:05

Astronomers at the universities of Southampton and Oxford have found evidence that neutron stars, which are produced when massive stars explode as supernovae, actually come in two distinct varieties. Their finding also suggests that each variety is produced by a different kind of supernova event. Neutron stars are the last stage in the evolution of many massive stars. They represent the most extreme form of matter: the mass of a single neutron star exceeds that of the entire sun, but...

SDO Spots Largest Sunspots In Years
2011-11-04 11:20:44

NASA's Solar Dynamics Observatory (SDO) spotted one of the largest new sunspots to have appeared on the surface of the sun in years. The area is nearly 25,000 miles wide, which is over three times larger than the Earth. NASA said the region has already experienced about eight solar flares, including an M-class flare on November 2. The space agency also said that X-class flares are possible, which includes the largest possible solar flares. The sun shot off a flare from this region...

ROSAT Fell To Earth Late Saturday Night
2011-10-23 05:37:41

The German-built Röntgensatellit (ROSAT) fell back to Earth Saturday evening, officials from the National Aeronautics and Space Administration (NASA) told ABC News. In a statement posted to their official website, the German Aerospace Center (DLR) said, "On Sunday, 23 October 2011, between 1:45 UTC (3:45 CEST) and 2:15 UTC (4:15 CEST) the German Roentgen Satellite ROSAT has re-entered Earth's atmosphere. There is currently no confirmation if pieces of debris have reached...

Image 1 - Astronomers Detect Water-Covered Planets

The Herschel Space Observatory has helped astronomers detect water-covered planets like Earth around a young star. The astronomers used data from Herschel to detect cold water vapor enveloping a dusty disk around the young star.  This is the first time scientists have found evidence of vast quantities of water extending out into the cooler, far reaches of disks where comets take shape.  The more water available in disks for icy comets to form, the greater the chances that...

The Secret Lives Of Solar Flares

  [ View the Video ] One hundred and fifty two years ago, a man in England named Richard Carrington discovered solar flares. It happened at 11:18 AM on the cloudless morning of Thursday, September 1st, 1859. Just as usual on every sunny day, the 33-year-old solar astronomer was busy in his private observatory, projecting an image of the sun onto a screen and sketching what he saw. On that particular morning, he traced the outlines of an enormous group of sunspots. Suddenly,...

Image 1 - Herschel Probes Dusty Past Of A Giant Star

  About 5 thousand million years from now, our Sun will expand into a red giant, swelling to such a size that it may swallow the Earth. It will then begin to shed huge amounts of dust, surrounding itself with an expanding circumstellar envelope (CSE) that ultimately will become a planetary nebula. New insights into this process have been revealed by ESA's Herschel Space Observatory, which is providing unprecedented images of the complex, outer structure of a nearby CSE. As part of...

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),...
