Latest Stars Stories
Astronomers recently got a rare opportunity to view a cosmic event that took place from 1837 to 1858 known as the "Great Eruption."
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.
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.
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.
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.
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.
A subset of data that helps map out the sun's magnetic fields was recently released from the Solar Dynamics Observatory (SDO).
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.
Georg Friedrich Julius Arthur von Auwers (September 12, 1838 "“ January 24, 1915) was a German astronomer born in GÃ¶ttingen, Germany. He attended the University of GÃ¶ttingen and worked at the University of KÃ¶nigsberg. 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 (Î± Sco), Graffias (Î²1 Sco), Dschubba (Î´ Sco), Sargas (Î¸ Sco), Shaula (Î» Sco), Jabah (Î½ Sco),...
