Massive Supernova And Nebula Seen In the Universe What secrets do these massive powerful events in our universe hold? Possibly our very future? PLEASE SUBSCRIBE A supernova (plural supernovae) is a stellar explosion that is more energetic than a nova. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval a supernova can radiate as much energy as the Sun is expected to emit over its entire life span. The explosion expels much or all of a star's material at a velocity of up to 30000 km/s (10% of the speed of light), driving a shock wave into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant. Several types of supernovae exist. Types I and II can be triggered in one of two ways, either turning off or suddenly turning on the production of energy through nuclear fusion. After the core of an aging massive star ceases generating energy from nuclear fusion, it may undergo sudden gravitational collapse into a neutron star or black hole, releasing gravitational potential energy that heats and expels the star's outer layers. Alternatively a white dwarf star may accumulate sufficient material from a stellar companion (either through accretion or via a merger) to raise its core temperature enough to ignite carbon fusion, at which point it undergoes runaway nuclear fusion, completely disrupting it. Stellar cores whose ...
Supernova 1987a Observations made with Hubble Space Telescope of the nearby supernova 1987a are allowing astronomers to measure the velocity and composition of "star guts" ejected into space following the explosion, according to a new study led by Kevin France of the Univ. of Colo.-Boulder and including J. Craig Wheeler of The Univ. of TX-Austin. More information: . Video credit: Peter Challis (CfA/Harvard) and NASA

Tycho's Supernova explosion in 1572 animation This animation shows how the explosion of Tycho's Supernova in 1572 most likely took place. In Type Ia supernova binary systems, the more massive star of the pair will age faster and eventually becomes a white dwarf star. When the slower-evolving companion star subsequently ages to the point where it begins to balloon in size, it spills hydrogen onto the dwarf. The hydrogen accumulates, gradually fusing into heavier elements until it reaches a critical and precise mass threshold, called the Chandrasekhar limit, where it explodes as a titanic nuclear fusion bomb. The companion star goes hurtling off into space, retaining the velocity of its orbital motion when the explosion disrupted the system. Credit: NASA, ESA and P. Ruiz-Lapuente (University of Barcelona)

New Supernova Is Discovered by Young Citizen Scientist There is no age restriction on the chance to make a significant contribution to our understanding of the universe. Caroline Moore, a 14-year-old from Warwick, NY, has made such a mark on astronomy with the discovery of Supernova 2008ha. Not only is she the youngest person to discover a supernova, but this particular supernova has been identified as a different type of stellar explosion.

Supernova Explosion w/Black Hole kick-out This video shows a black hole and its yellow companion star being sent out on a out on a long journey through the Milky Way galaxy by the explosive kick of a supernova - one of the Universe's most titanic events. New observations made by the ESA/NASA Hubble Space Telescope have allowed astronomers to measure the motion of this black-hole system across the sky using images taken in 1995 and 2001. The results are surprising: the black hole streaks across the plane of our Milky Way at a velocity 4 times that of stars around it! This is the first direct link between black holes and the supernovae that create them.

Supernova _ the most realistic computer simulation untill now
Project Universe - Supernovae and Pulsars (1 of 3) Electron degeneracy pressure limits lower mass stars from burning carbon into oxygen and evolving further. Stars higher than 4 solar masses will go supernova when carbon is burned into oxygen and so on up the atomic numbers until no more nuclear energy is available. The star then collapses catastrophically and ignites a different type of energy process called particle reaction which suddenly release a vast amount of energy, causing the star to blow up.
22. Supernovae Frontiers/Controversies in Astrophysics (ASTR 160) Professor Bailyn offers a review of what is known so far about the expansion of the universe from observing galaxies, supernovae, and other celestial phenomena. The rate of the expansion of the universe is discussed along with the Big Rip theory and the balance of dark energy and dark matter in the universe over time. The point at which the universe shifts from accelerating to decelerating is examined. Worries related to the brightness of high redshift supernovae and the effects of gravitational lensing are explained. The lecture also describes current project designs for detecting supernovae at high or intermediate redshift, such as the Joint Dark Energy Mission (JDEM) and Large Synoptic Survey Telescope (LSST). Complete course materials are available at the Open Yale Courses website: open.yale.edu This course was recorded in Spring 2007.

Supernova explosion A supernova (pl. supernovae) is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova can radiate as much energy as the Sun could emit over its entire life span. The explosion expels much or all of a star's material at a velocity of up to 30000 km/s (a tenth the speed of light), driving a shock wave into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.

Animation Of Supernova Aftermath [720p] This video animation shows the remnant of the explosion of a supermassive star. Stars greater that eight times the mass of our Sun will self-detonate as supernovae. Supernovae can briefly outshine an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova radiates as much energy as the Sun could emit over its entire lifespan. The star is shredded and blown into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant. Hubble Space Telescope spectroscopic observations have yielded the chemistry cooked up by the supernova, including oxygen, nitrogen and carbon the basis of life as we know it.

Type IA Supernovae en. A supernova is one way that a star can end its life, exploding in a display of grandiose fireworks. One family of supernovae, called Type Ia supernovae, are of particular interest in cosmology as they can be used as standard candles to measure distances in the Universe and so can be used to calibrate the accelerating expansion that is driven by dark energy. One defining characteristic of Type Ia supernovae is the lack of hydrogen in their spectrum. Yet hydrogen is the most common chemical element in the Universe. Such supernovae most likely arise in systems composed of two stars, one of them being the end product of the life of sun-like stars, or white dwarfs. When such white dwarfs, acting as stellar vampires that suck matter from their companion, become heavier than a given limit, they become unstable and explode.

Supernova birth seen for first time Date- 22 May 09 Source- www.ciw.edu 'Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. While looking at another object in the spiral galaxy NGC 2770, using NASAs orbiting Swift telescope, Carnegie-Princeton fellows* Alicia Soderberg and Edo Berger detected an extremely luminous blast of X-rays released by a supernova explosion. They alerted 8 other orbiting and on-ground telescopes to turn their eyes on this first-of-its-kind event.' More info- www.ciw.edu
Echoes Of A Supernova Science & Reason on Facebook: The Hidden Universe (Episode 20): Cassiopeia A - Echoes of a Supernova A supernova flash echoing through surrounding dust clouds has given astronomers a virtual time machine for studying the light from the explosion that nobody saw. This is the Hidden Universe of NASA's Spitzer Space Telescope, exploring the mysteries of infrared astronomy with your host Dr. Robert Hurt. --- Please subscribe to Science & Reason: • • • • --- It's the 17th century supernova that nobody saw, but telescopes in space and on Earth have teamed up to look back in time and study it today! When a massive star reaches its end of days it explodes dramatically and, for a few months, can outshine anything else in the galaxy. Earlier supernovas had been seen by many, often shining brighter than the planets. Of course with no witnesses, and no records, it's difficult to tell exactly what kind of supernova it was. A team led by astronomer Oliver Krause has, over the last few years, made a remarkable series of infrared observations of the region. These Spitzer Space Telescope images show shifting patterns of glowing dust beyond the remnant itself. These changes are so fast that they indicate motion at the speed of light! To get what's happening we have to remember that light moves fast, but in such a vast galaxy it still takes a while for it to get anywhere. Cassiopeia A (Cas A) itself is about 11000 ...

The Orb - Supernova At The End Of The Universe
Supernovas: When Stars Die When a star explodes, it leaves behind a debris field of stellar material and high-energy particles known as a supernova remnant. Astronomers use Chandra to study these remnants that can produce intense X-ray radiation for thousands of years. Supernova remnants are responsible for seeding cloud that formed our Sun, planets, and ultimately us with elements like nitrogen and oxygen.

Kathryn Aurora Gray - Youngest Supernova Discovery Age is no barrier when it comes to supernova hunting, as 10-year-old Kathryn Gray has just proven. The Canadian schoolgirl was scanning through astronomical images on Jan. 2 when she made the record-breaking find. According to the Royal Astronomical Society of Canada, Kathryn is the the youngest ever discoverer of a supernova. The supernova was spotted erupting to life in the constellation of Camelopardalis in a galaxy called UGC 3378, some 240 million light-years distant. Shining at a brightness of magnitude 17, the flash was imaged on New Year's Eve. Magnitude 17 is the approximate brightness of the dwarf planet Haumea (in the Kuiper Belt) as seen from Earth. Helped by her amateur astronomer father Paul Gray, Kathryn was taught how to look out for these transient flashes using a computer program that compares new and old images of the same portion of the night sky. Blinking between the new and old images, anything like the motion of planets, asteroids or supernovae can be spotted. It is an arduous task, and a significant discovery for any astronomer, but Kathryn was determined to become the youngest person to make a supernova discovery. "I'm really excited. It feels really good," Kathryn told the Canada Star newspaper on Monday. Kathryn showed an interest in astronomy last year and became fascinated with trying to find a supernova when she learned that the previous record was held by a 14-year-old. The supernova, called SN 2010lt, was observed by Dave Lane, an amateur ...
