IMAGE: Remnant Of An Explosion With A Powerful Kick?
2012-02-02 13:47:04

Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy. The latest example of this important investigation is Chandra's new image of the supernova remnant known as G350.1+0.3. This stellar debris field is located some 14,700 light years from the Earth toward...

Image 1 - La Silla Observatory Captures A Pocket Of Star Formation
2012-02-01 11:55:05

[ Watch the Video ] This new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. The intense ultraviolet radiation from several of NGC 3324's hot young stars causes the gas cloud to glow with rich colors and has carved out a cavity in the surrounding gas and dust. NGC 3324 is located in the southern constellation of Carina (The Keel, part of Jason´s ship the Argo) roughly...

Image 1 - 'Cool' Gas May Form And Strengthen Sunspots
2012-02-01 05:19:44

Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope. "We think that molecular hydrogen plays an important role in the formation and evolution of sunspots," said Dr. Sarah Jaeggli, a recent University of Hawaii at Manoa graduate whose doctoral research formed a key element of the new findings. She conducted the research with Drs....

NASA Captures Another Massive Solar Flare On January 27: Video
2012-01-30 10:35:37

[ Watch the Video ] The sun unleashed an X1.8 class flare that began at 1:12 PM ET on January 27, 2012 and peaked at 1:37. The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow....

Comet Corpses In The Solar Wind
2012-01-21 04:13:51

[ Watch the Video ] A paper published in the Jan. 20th issue of Science raises an intriguing new possibility for astronomers: unearthing comet corpses in the solar wind.  The new research is based on dramatic images of a comet disintegrating in the sun's atmosphere last July. Comet Lovejoy grabbed headlines in Dec. 2011 when it plunged into the sun's atmosphere and emerged again relatively intact.  But it was not the first comet to graze the sun. Last summer a smaller comet...

SDO Helps Measure Magnetic Fields On The Sun's Surface
2012-01-19 13:34:38

[ Watch the Video ] A subset of data that helps map out the sun's magnetic fields was recently released from the Solar Dynamics Observatory (SDO). Observations that measure the strength and direction of magnetic fields on the solar surface -- known as vector magnetograms -- play a crucial role in understanding how those fields change over time and trigger giant eruptions off the surface of the sun such as solar flares and coronal mass ejections (CMEs). Collecting the information needed...

Astronomers Solve 40-year Mystery Of Nearby Supernova
2012-01-12 05:57:49

NASA's Hubble Space Telescope has helped astronomers solve a 40-year mystery over what type of star, or so-called progenitor, caused a supernova in a nearby galaxy. The powerful telescope´s findings have provided new observational data for identifying one of several scenarios that trigger such outbursts. Based on previous observations from ground-based telescopes, astronomers knew the supernova class, called a Type Ia, created a remnant named SNR 0509-67.5, which lies 170,000...

Rossi X-Ray Timing Explorer Completes Mission Operations
2012-01-10 07:18:27

After 16 years in space, NASA's Rossi X-ray Timing Explorer (RXTE) has made its last observation. The satellite provided unprecedented views into the extreme environments around white dwarfs, neutron stars and black holes. RXTE sent data from its last science observation to the ground early on Jan. 4. After performing engineering tests, controllers at NASA's Goddard Space Flight Center in Greenbelt, Md., successfully decommissioned the satellite on Jan. 5. RXTE far exceeded its original...

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),...
