Since that was a supernova explosion, that would most likely produce all elements that occur naturally, except hydrogen (element #1).
Depending on the mass of the original star, it is either a black hole or a neutron star.
The one that is next observed.
I THINK either everything will die or all the planets will be pushed into another solar system
This is just my predicition JUST OPINIONS
Actually, the entire solar system will be obliterated. What happens is, the sun will start to go into the red giant stage and will start expanding outward. It starts to engulf the solar system and so on and so forth. So then, it starts shrinking back to normal and becomes a cold white dwarf. By the time all that has happened, the solar system would have become a thing of the past. I'm assuming that it will happen in around a few billion years. It won't go supernova because it's not big enough.
The red giant phase of a star like ours (Class G2) would likely come very close to the orbit of Earth, but would not extend further. Earth would probably be demolished, and Mars scorched to a molten cinder. I would expect the gas giants to be considerably less giant when the sun shrinks back to begin fusing helium. Any way you look at it, though, it won't be a good place for any form of life we know of. Luckily, we likely have a couple billion years to find some way to be somewhere else when that time comes.
By accretion of hydrogen from a nearby star which ignites and starts nuclear fusion in a runaway manner. The explosion is only on the surface of the white dwarf - this is a nova [See related question]
If however, it accretes enough hydrogen to push it's mass over the Chandrasekhar limit [See related link] of about 1.38 solar masses, the whole white dwarf will explode as a supernova type Ia [See related link]
A hypernova [See related question]
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
A pulsar is a rapidly spinning neutron star, the collapsed core of a nova explosion, while a white dwarf is the remains of a small star whose fuel is about used up. A pulsar or neutron star is far more dense than a white dwarf.
No, some leave a black hole instead of a neutron star.
The Sun is an averaged size star so it doesn't have enough mass to explode. Instead it reheats and expands into a red giant, so earth will be vaporized within the sun! Oh yeah and don't freak out, it's not going to happen within 5 billion years. Plenty of time to get that degree and a good job, and to raise a family. In four billion years 4,000,000,000 Roughly 4-5 billion years but the Sun will not go dark for roughly 20-30 billion years.
Although the Sun will continue to shine for billions of years Earth will be uninhabitable in roughly 1 billion years this is because as the Sun ages it gets hotter and brighter and in about 1 billion years the temp on Earth will be too hot for liquid water to exist on the surface.
According to Scientific American: "The North Star, or Polaris, is the brightest star in the constellation Ursa Minor, the little bear (also known as the Little Dipper)."
Click on the link to the right for their full article (with a picture showing the location).AnswerAnother way to find Polaris is to locate the Big Dipper (Ursa Major) which is usually easy to find from the Northern hemisphere, and then look at the two stars on the lip, or front side of the cup. These are Merak, on the bottom, and Dubhe on the tip of the lip. If you estimate the distance between these two and then follow a line straight up from Merak through Dubhe about three times that distance, you will find Polaris. It will appear to be approximately due North from any place it can be seen (which is nice for orienting yourself at night). As mentioned above, Polaris is also part of the Little Dipper (Ursa Minor) and is the star at the end of the handle.
Because Polaris lies nearly in a direct line with the axis of the Earth's rotation "above" the North Pole - the north celestial pole - Polaris stands almost motionless on the sky, and all the stars of the Northern sky appear to rotate around it. Therefore, it makes an excellent fixed point from which to draw measurements for celestial navigation and for astrometry.Additional AnswerIf you mean where in space is the star, relative to earth, it is 431 light years away from earth, about 2 degrees away from a line going from the south pole through the north pole.
The web site in the related links also shows the direction of Polaris relative to Earth in the galaxy.
If the Sun was replaced by Orion's star Betelgeuse , its size would completely engulf the earth. Also it would extend past the orbit of Jupiter, and most of the planets would be inside the star including Jupiter. Betelgeuse would outshine the Sun like our Sun outshines the Moon. Unfortunately the Earth would have a "Front Row Seat" when the Red SuperGiant blows itself into oblivion. The explosion would be so bright that the star in Orion (constellation) which is 640 Light Years away. Days would still change from day into night, but for a few weeks or so it would appear like there are two Suns in the sky.
this is what would happen when Betelgeuse explodes :)
A Nova [See Link] is a fusion reaction in the accretion layer (the superficial shell) of a white dwarf star, which is slowly stealing material from a companion in a binary system. In the case of an instability in the accretion disk itself, the event is called a dwarf nova.
This can occur once or many times. RS Ophiuchi has erupted in 1898, 1933, 1958, 1967, 1985, and 2006. It is in it's "quiet" phase at the moment, but will more than likely erupt again in the future.
If a nova accretes enough mass to pass the Chandrasekhar limit then the whole star will explode as a type I-a supernova.
A Supernova [See Link] is the catastrophic destructive event caused by the core collapse of a large star.
The term "nova" is generically applied to exploding stars, but is more technically a flare-up of fusion activity on the outer surface of a white dwarf star. A "supernova" is a more extreme version involving the gravitational collapse of a very large star. In this process, the outer layers fall in on the star's core, then are violently blasted away.
A supernova is therefore the "death" of a star, as fusion will normally end afterward, leaving a neutron star or black hole. The explosion also creates a nebula of illuminated gas that is one of the most visible of all celestial phenomena.
The supernova process is caused by the exhaustion of nuclear "fuel" (lighter elements) within the star, so that the reactions are no longer able to resist the gravity trying to compress the solar mass into the core. The star collapses, causing the outer layers to violently explode outward as gases and dust. The remnant core may become a super- compressed neutron star or possibly a black hole.
(For details on "nova", see related questions and link.)
(For details on "supernova remains" see related question and link.)
The Orion nebula was likely caused by a supernova. It is a huge cloud of gas within which hundreds of new stars are being formed.
Xibalba is the name of the Mayan underworld ... essentially the equivalent of the Greek Hades (the place, not the god). Also, the Mayans appear to have regarded a dark rift in the Orion Constellation as being the road to Xibalba. On Ganymede, one of Jupiter's moons, there is a feature (a sulcus, which is basically a kind of ditch) named after it; that's the only modern non-fictional astronomical reference to it that I know of The nebula in the movie, The Fountain, is referred to as Xibalba, which the Mayans believed to be the Orion Nebula. There is no star or nebula technically referred to as Xibalba, but as you can see throughout the movie, it is shown to be within the constellation Orion and specifically the location of the Orion Nebula. According to Wikipedia: "The Maya of Central America had a folk tale which dealt with Orion's part of the sky, known as Xibalba. Their traditional hearths included in their middle a smudge of glowing fire that corresponded with the Orion nebula. This is clear pre-telescope evidence that the Maya detected a diffuse area of the sky contrary to the pin points of stars."
1. Power off the Nova by holding the power button for two seconds until you see "Power Off" on the screen. Choose the "power off" option and then press the "Ok" button. Let the device completely power down before you continue with the next steps. At this time also remove any SD card you might have inserted into the device.
2. Press and hold the volume + button. While still holding this button, press down on the power button. You will then see a screen that says Pandigital. This is the boot screen.
3. After the device boots up you will go to a black screen with triangle, press volume + button and the power button. What should come up is a screen with blue text, this is the system recovery screen. While on the system recovery screen, press the volume - button until "wipe data and cache" is highlighted. Press the power button to select this option
4. Press the volume - button until "Yes -- delete all user data" is highlighted. Press the power button to select this option.

6. "Reboot system now" should be highlighted by default. Press the power button to select this option. (this is directly from pandigital customer service)
It didn't. It occurred approximately 168,000 years before 1987.
slow cooling. it can't ignite fusion.
Red Dwarfs have surface temperatures ranging from about 2300 K up to maybe 4000 K.
A few elements past iron can form in the star by neutron capture and beta decay. However the majority can only be formed by the blast shockwave of a supernova, which can form elements significantly beyond Uranium.
The brightest star is the Sun. See related question.
A nebula is a large cloud of gas in space, a planetary nebula is the large cloud of expanding superheated gas caused by the explosion of a red giant or other very large, very hot star.
Neither have anything to do with planets.
Although not noted as a supernova, the nebula "Cassiopeia A" was first observed by John Flamsteed on August 16, 1680. It is likely that intervening dust clouds obscured the brightness of the supernova, which might otherwise have been observed in 1667.
Current estimates place the distance from Earth as around 11,000 light years. If that is correct, then the supernova explosion actually took place around 9,000 BCE. (see related link)
