Project. In October 1604 a giant supernova unexpectedly exploded in the constellation of Ophiucus and its bright light remained visible to the naked eye for many months. At first it was regarded as the insurgence of a “new star” or stella nova, although it was actually a “dying” star or a “supernova”, as today we know.
Stars do explode, and when that happens they're known as supernovae. A supernova creates an explosion billions of times brighter than our sun, with enough energy to outshine its own galaxy for weeks. These massive explosions throw large amounts of matter out into space.
When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This entire process will take a few billion years.
Sun-sized stars die slowly, giving off puffs of gas and dust known as planetary nebulas to reveal small white dwarfs. Massive stars die suddenly in powerful explosions known as supernovas, blasting gas, dust, and energy out in all directions as they collapse to form tiny neutron stars or black holes.
The original Death Star's completed form appears in the original Star Wars film, known as the DS-1 Orbital Battle Station, or Project Stardust in Rogue One; before learning the true name of the weapon, the Rebel Alliance referred to it as the "Planet Killer".
The events at the end of a star's life depend on its mass. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a 'supernova'.
A Memorial Star is an extraordinarily powerful gift that will mean the world to the family or friends who have lost someone special. The star's continued presence in the polar sky helps keep memories alive with a simple glance at the heavens on a clear, starry night.
If the mass is less than about 3 times the mass of the Sun, what is left is a very small, extremely dense object known as a neutron star. When the collapsing core is more massive than this limit, it continues collapsing and becomes one of the strangest objects in our universe: a black hole.
Meteors: When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors.
A supernova ( pl. : supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion.
Once the star's core surpasses a certain mass (called the Chandrasekhar limit), it begins to implode. For this reason, these Type-II supernovae are also known as core-collapse supernovae. Eventually, the implosion bounces back off the core, expelling the stellar material into space, forming the supernova.
An exploding star is called a supernova. It's either a giant star ending its life, or a white dwarf that becomes too big. A supernova briefly shines as brightly as billions of suns!
Complete answer: 1) Supernovae are colossal explosions that occur when certain types of stars die. When a star, such as the Sun, dies, its outer layers are ejected into space, leaving its hot, dense core to cool over aeons. A supernova can have the same brightness as a galaxy of billions of "regular" stars.
Answer and Explanation: A collapsed star is called a neutron star. A star collapses when the core of the star runs out of hydrogen and can no longer continue to create enough pressure to balance the press of gravity.
The sudden violent death of a star is called a 'supernova'. Supernovas occur in stars that are roughly eight to fifteen times the size of the Sun. A supernova occurs when a massive star runs out of hydrogen in its core. The outward pressure from the fusion reaction is gone and the star collapses in on itself.
Dead stars are called "stellar remnants" or "remnant objects." These include white dwarfs, neutron stars, and black holes, which are formed from the remnants of stars that have exhausted their nuclear fuel and undergone supernova explosions.
Death, or Thanatos, is the opposite of Life. Death is represented as a male, and life as a female. He is the twin brother of Hypnos, the god of Sleep. He is discripted as gentle, he escorts the dead to the Underworld, Hades.
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."
Ultraviolet light from the dying star makes the material glow. The burned-out star, called a white dwarf, is the white dot in the centre. Our Sun will eventually burn out and shroud itself with stellar debris, but not for another five thousand million years.
After the star's outer layer has escaped, the much smaller inner layer collapses into a white dwarf. This star, which is hotter and brighter than the red giant it came from, illuminates and warms the escaped gas, until the gas starts glowing by itself – and we see a planetary nebula.
A highly secure supply line with various false routes and outposts was developed to ensure further secrecy, and it was during that time that the battle station was given the official name of Death Star and given the hull designation of DS-1, though the early codename, Stardust was still used in design files.

In that it's opposite in function but similar in scale. Both were huge space stations made by the galaxy's controlling power to spread their influence. The Death Star did so through destruction, a trait associated with the dark side. Starlight did so through aid, a trait associated with the light side.
