The second type of supernova (.type 1A) happens when a tiny white dwarf star is in orbit around a much larger star. Material from the larger star falls onto the surface of the white dwarf and accumulates. Over time, this accumulation becomes so great that an immense nuclear explosion takes place on the white dwarf surface (en.allexperts.com....nova-1.htm)
first supernova observed in 1987 (hence its designation) and the nearest to Earth in more than three centuries. It occurred in the Large Magellanic Cloud , a satellite galaxy of the Milky Way Galaxy that lies about 160,000 light-years distant.

In February 1987 observers on Earth witnessed the explosion of a star in the nearby Large Magellanic Cloud galaxy-the brightest supernova seen in more than three centuries. As Supernova 1987A became dimmer, astronomers detected an encircling ring of glowing gas about a light-year in radius. It was believed that the ring was composed of gas that had been ejected .

The first supernova visible to the naked eye in almost four centuries was discovered on Feb. 24, 1987. Named supernova 1987A (SN 1987A), it was spotted almost simultaneously by astronomers in Chile and by an amateur sky watcher in New Zealand. Visible only from the Southern Hemisphere, SN 1987A lay in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It was (www.britannica.com....nova-1987A)
On the morning of Feb. 24, 1987, astronomers at two observatories in Chile saw a burst of light in the Large Magellanic Cloud, a nearby galaxy. Later named Supernova 1987A, this exploded star marked the first known supernova visible to the naked eye since 1604. From thousands of observatories throughout the world, such astronomical phenomena are continually monitored, (www.britannica.com....nova-1987A)

While previous research has suggested instability of electron-positron pairs leading to supernova behavior, the new study is the first time that it has been suggested that such repeated instability in pulses creates very bright supernova (www.topnews.in....sion-26299)
The energy from such a stellar cataclysm generates a shock wave an expanding bubble of highly energetic particles. These supernova remnants, as they are called, are found throughout our galaxy. (www.space.com....41004.html)
Weekes said there are a variety of different energy spectra from supernova remnants, but the spectrum from the galactic center looked similar to that from the Crab Nebula. A spectrum is the rainbow of colors from light, as when it goes through a prism, which can be analyzed for chemical signatures and other clues about the source (www.space.com....41004.html)
However, the HESS collaboration claims that, as in the case of the black hole jet, there are problems rectifying the X-ray and radio measurements of the galactic center's supernova remnant with the gamma ray measuremen (www.space.com....41004.html)
I have a copy of National Geographic and another book mentioning the now famous Supernova Sanduleak SN1987A. Both were published soon after the discovery and mention that no Neutron Star had yet been detected at the core. Has that Neutron Star now been detected?

On the last afternoon of the Supernova Conference, David Weinberger and fellow ZD Net blogger Andrew Keen, debated the question, "Disorder: Feature or Bug?" Unfortunately, they didn't actually manage to demonstrate a definitive answer to that question, because all we learned was that they disagreed. Chris Heuer took notes. Keen, (updates.zdnet.com....rnova.html)

Well, the Benelli SuperNova scattergun I recently bought at a Pre-Shot shoot did me pretty well at the range this past weekend. I went with Dad and a friend and threw some clays, and I did a lot more hitting than missing with the Benelli but I did have to re-teach myself to pump it.

BRIGHTEST SUPERNOVA : SN 2006gy, discovered last September , may have exploded by a process known as pair-instability, in which gamma rays turn to short-lived particles instead of providing heat and pressure to support the sta (www.sciam.com....y-reignite)
Since SN 2006gy was discovered, astronomers have noticed a second, even brighter supernova that was first observed in 2005 but lasted for an ordinary amount of time. Smith notes that a third explosion nearly matched the brilliance and duration of SN 2006gy, which has hogged the spotlight (www.sciam.com....y-reignite)
A supernova is an exploding star that can become billions of times as bright as the sun before gradually fading from view. At its maximum brightness, the exploded star may outshine an entire galaxy. The explosion throws a large cloud of dust and gas into space. The mass of the expelled material may exceed 10 times the mass of the sun (www.nasa.gov....dbook.html)
In 1054, Chinese astronomers recorded a supernova so bright that it was visible during the day. The explosion left behind a pulsar and a huge cloud of gas and dust known as the Crab Nebula, which still can be seen toda (www.nasa.gov....dbook.html)
In 1987, a Type II supernova became visible in the Large Magellanic Cloud, the galaxy closest to the Milky Way. It was the first supernova to be visible to the naked eye in almost 400 years. It could be viewed only from the Southern Hemisphere (www.nasa.gov....dbook.html)
