THE SUPERNOVAS
When a star explodes it leaves behind a debris field of stellar material and high-energy particles that bears the name of supernova remnant. Astronomers use NASA's Chandra to study these remnants that can produce intense X-ray radiation for thousands of years. The supernova remnants are responsible for seeding the clouds that formed the Sun, the planets and even us with elements such as nitrogen and oxygen.
A supernova is the explosive death of a star. It is one of the most energetic events in the Universe and can temporarily eclipse the rest of the galaxy where it is located, it is indicated in a video of the Chandra Observatory of the NASA space agency.
A supernova is a stellar explosion that can be so notorious that it can be seen with the naked eye.
Supernovae produce flashes of light that can last for weeks or months. One of its main characteristics is that they have a rapid increase in luminosity until reaching an absolute magnitude greater than the rest of the galaxy. Then the brightness decreases until it disappears.
Every 50 years or so, a massive star in our galaxy explodes into what astronomers call a supernova. Supernovas are some of the most violent events in the Cosmos. The force of the explosion generates an intense flash of radiation, as well as shock waves analogous to supersonic booms. These supernovas are usually better observable through telescopes like the Chandra.
NASA REVEALS WHAT HAPPENED WITH SUPERNOVA 1987A IN VIDEO
The US space agency, NASA, has revealed a video time lapse with images obtained by the Hubble Space Telescope that shows the dramatic changes in a ring of material around supernova 1987A.
They are also called 'black holes' and are finite regions of space that generate a gravity field from which no particle, not even light, can escape.
Black holes, according to their mass are classified into three types: supermassive, stellar mass and micro black holes.
It is believed that at the center of most galaxies there are supermassive black holes.
NASA: AGONIZING STAR GIVES LIFE TO A BLACK HOLE ... WITHOUT SUPERNOVA?
Astronomers have observed how a massive dying star may have been reborn as a black hole, without the supernova explosion, NASA said through its website.
NASA is the National Aeronautics and Space Administration of the United States.
It was founded by President Dwight D. Einsenhower in 1958 with a civil orientation.
Between the most important successes of the nasa are the missions Apollo that arrived at the Moon. Currently supports the International Space Station, while exploring other planets, stars, being its closest target Mars, the red planet.
