An international team of astronomers using the Hubble Space Telescope reports a significant brightening of the emissions from Supernova 1987A. The results, which appear in this week's Science magazine, are consistent with theoretical predictions about how supernovae interact with their immediate galactic environment. The team observed the supernova remnant in optical, ultraviolet, and near-infrared light. They studied the interaction between the ejecta from the stellar explosion and a glowing...

Astronomers using ESO's Very Large Telescope have for the first time obtained a three-dimensional view of the distribution of the innermost material expelled by a recently exploded star. The original blast was not only powerful, according to the new results. It was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models. Unlike the Sun, which will die rather quietly, massive...

New computer models show in detail how supernovae obtain their shape Massive stars end their lives in gigantic explosions, so called supernovae, and can become - for a short time - brighter than a whole galaxy, which is made up of billions of stars. Although supernovae have been studied theoretically by computer models for several decades, the physical processes happening during these blasts are so complex that until now astrophysicists could only simulate parts of the process and so far only...

An international team of astronomers, led by Keiichi Ohnaka at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, has made the most high resolution images of a dying giant star to date. For the first time they could show how the gas is moving in different areas over the surface of a distant star. This was made possible by combining three 1.8 meter telescopes as an interferometer, giving the astronomers the resolving power of a virtual, gigantic 48 meter telescope. Using the ESO VLT...

NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the star should not have self-destructed so early in its life. "This might mean that we are fundamentally wrong about the evolution of massive stars, and that theories need revising," says Avishay Gal-Yam of the Weizmann Institute of Science, Rehovot, Israel. The doomed star, which is estimated to...

Powerful nearby supernova caught by web of telescopes Over a decade after it exploded, one of the nearest supernovae in the last 25 years has been The supernova, called SN 1996cr, was first singled out in 2001 by Franz Bauer. Bauer noticed a bright, variable source in the Circinus spiral galaxy, using NASA's Chandra X-ray Observatory. Although the source displayed some exceptional properties Bauer and his Penn State colleagues could not identify its nature confidently at the time. It was...

A delicate ribbon of gas floats eerily in our galaxy. A contrail from an alien spaceship? A jet from a black-hole? Actually this image, taken by NASA's Hubble Space Telescope, is a very thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago. On or around May 1, 1006 A.D., observers from Africa to Europe to the Far East witnessed and recorded the arrival of light from what is now called SN 1006, a tremendous supernova explosion caused by the...

By Luntz, Stephen Australian astronomers have successfully bid for a 10 Gb/s data link across the US. The link will be used to demonstrate the practicality of moving the enormous amounts of data produced by major telescopes over large distances. "This wilt be important for demonstrating techniques that will be used for the international Square Kilometre Array radio telescope (AS, April 2008, pp.20-22)," said Prof Brian Boyle, Director of CSIRO's Australia Telescope National Facility. The...

NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula "” the shattered remains of a supernova that exploded thousands of years ago. This series of images provides beautifully detailed views of the delicate, wispy structure resulting from this cosmic explosion. The Veil Nebula is one of the most spectacular supernova remnants in the sky. The entire shell spans about 3 degrees on the sky, corresponding to about 6 full moons. The Veil Nebula is a...

Today, February 24th, is the 20th anniversary of the discovery of Supernova 1987A (SN1987A), the most famous supernova of our time. We asked Dick McCray, one of the foremost authorities on the outburst and its aftermath, whether SN1987A has become a supernova remnant, or are we still observing a supernova. "It's a bit like the question of whether Pluto should be called a planet, except that people won't feel as passionate about the matter," McCray responded, and then added, "Maybe it's...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
