XMM-Newton has, for the first time, detected signals from both stars of a binary pulsar system in X-rays, unveiling a scientific goldmine. Each star of the closely-packed system is a dense neutron star, spinning extremely fast, radiating X-rays in pulses. The binary pulsar PSR J0737-3039 was first spotted by astronomers in 2003 in radio wavelengths. X-rays can be used to probe deeper and study the system more thoroughly. To see two pulsars orbiting each other in a binary system is extremely...

NSF-funded basic research may cause astronomers to re-examine the masses and ages of young stars and star formation theories Two stars, each with the same mass and in orbit around each other, are twins that one would expect to be identical. So astronomers were surprised when they discovered that twin stars in the Orion Nebula, a well-known stellar nursery 1,500 light years away, were not identical at all. In fact, these stars exhibited significant differences in brightness, surface...

For more than 400 years, astronomers have studied the sun from afar. Now NASA has decided to go there. "We are going to visit a living, breathing star for the first time," says program scientist Lika Guhathakurta of NASA Headquarters. "This is an unexplored region of the solar system and the possibilities for discovery are off the charts." The name of the mission is Solar Probe+ (pronounced "Solar Probe plus"). It's a heat-resistant spacecraft designed to plunge deep into the sun's atmosphere...

ESA's orbiting gamma-ray observatory, Integral has revealed a new population of exotic and dusty binary stars which might represent a brief evolutionary period in a binary star's life. The findings bring to light a gap in our knowledge of the formation and evolution of such binary star systems. Since 2002, when Integral was launched, the observatory has been surveying the galaxy, looking for sources of the most powerful X-rays and gamma rays. Fifteen of its new discoveries appeared to be...

Pasadena, Calif. -- NASA's Spitzer Space Telescope has found a bizarre ring of material around the magnetic remains of a star that blasted to smithereens. The stellar corpse, called SGR 1900+14, belongs to a class of objects known as magnetars. These are the cores of massive stars that blew up in supernova explosions, but unlike other dead stars, they slowly pulsate with X-rays and have tremendously strong magnetic fields. "The universe is a big place and weird things can happen," said...

On April 25, NASA's Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable in the night sky at the time.The star, known as EV Lacertae, isn't much to write home about. It's a run-of-the-mill red dwarf, by far the most common type of star in the universe. It shines with...

Many solar scientists expected the new sunspot cycle to be a whopper, a prolonged solar tantrum that could fry satellites and raise hell with earthly communications, the power grid and modern electronics. But there's scant proof Sunspot Cycle 24 is even here, let alone the debut of big trouble. So far there have been just a couple minor zits on the face of the sun to suggest the old cycle is over and the new one is coming. The roughly 11-year cycle of sunspot activity should have bottomed...

Astronomers have discovered a rare type of star called a pulsar that they believe is locked in an elongated orbit around a star much like the sun. The spinning pulsar is called J1903+0327 and is located about 21,000 light years (About 6 trillion miles) from Earth. A pulsar is created when a massive star explodes as a supernova, astronomers said."The big question is"”how in the heck did this thing form, because it doesn't follow our standard models of how these things form," astronomer...

Images from the twin STEREO spacecraft show, for the first time, a solar tsunami blasting its way through the Sun's lower atmosphere. The discovery will be presented by David Long at the RAS National Astronomy Meeting in Belfast on Wednesday 2nd April.Solar tsunamis are launched by huge explosions near the Sun's atmosphere, called coronal mass ejections (CMEs). Although solar tsunamis share much in common with tsunamis on Earth, the solar version can travel at over a million kilometers per...

An international team of astronomers has found 10 new "extra solar" planets, planets that orbit stars other than our sun. The team used a system of robotic cameras that yield a great deal of information about these other worlds, some of which are quite exotic. The system is expected to revolutionize scientific understanding of how planets form.Two participating astronomers from the U.S. are Rachel Street and Tim Lister. Street is a postdoctoral fellow at the University of California, Santa...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
