Using radio and infrared telescopes, astronomers have obtained a first tantalizing look at a crucial early stage in star formation. The new observations promise to help scientists understand the early stages of a sequence of events through which a giant cloud of gas and dust collapses into dense cores that, in turn, form new stars. The scientists studied a giant cloud about 770 light-years from Earth in the constellation Perseus. They used the European Space Agency's Herschel Space...

Image 1 - RXTE Captures Thermonuclear Behavior Of Unique Neutron Star
2012-03-11 07:04:11

A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the star's surface. NASA's Rossi X-ray Timing Explorer (RXTE) captured the month-long fusillade in extreme detail. Using this data, an international team of...

Image 1 - Important Clue Uncovered For Origins Of A Type Of Supernovae Explosion

Pitt team used Sloan Digital Sky Survey to determine that the merger of double white dwarfs is a plausible explanation for Type Ia supernovae The origin of an important type of exploding stars–Type Ia supernovae–have been discovered, thanks to a research team at the University of Pittsburgh. Studying supernovae of this type helps researchers measure galaxy distances and can lead to important astronomical discoveries. A paper detailing this research has been accepted for...

Scientists Make New Neutron Star Discovery

Researchers from several universities have detected all phases of thermonuclear burning in a neutron star for the first time. The team discovered the "model burster" star located close to the center of the galaxy in the global cluster Terzan 5. The star is the first of its kind to burst the way that models predict, and it could help explain why a model star like it has gone undetected for so long. Astrophysicists have been studying neutron stars for decades to try and understand how...

Astronomers Clock Record Wind In Stellar-Mass Black Hole
2012-02-21 15:21:23

Astronomers have clocked the fastest wind yet ever discovered blowing off a disk around a stellar-mass black hole. The team used NASA's Chandra X-ray Observatory to discover that the wind at this black hole is moving about 20 million miles per hour, or about 3 percent of the speed of light. According to NASA, this is nearly 10 times faster than other winds that have been seen around other stellar-mass black holes. "This is like the cosmic equivalent of winds from a category five...

Image 1 - Light Echoes Allow Astronomers To Watch 'Great Eruption' Replay
2012-02-15 14:52:36

Astronomers recently got a rare opportunity to view a cosmic event that took place from 1837 to 1858 known as the "Great Eruption." The outburst temporarily made Eta Carinae the second brightest star in the sky during that period. Today's astronomers are able to view the event because some of the light from the eruption took an indirect path to Earth and is just now arriving. The light was heading in a different direction, away from our planet, when it bounced off dust lingering far...

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),...
