What is a supernova?

A supernova is a stellar explosion and is the largest explosion to occur in space.

Supernovae usually occur in other galaxies. However, it is difficult to see supernovae in the Milky Way because dust prevents us from seeing.


In 1604, Johannes Kepler discovered the last supernova that occurred in the Milky Way. NASA’s Chandrai Telescope has discovered the remains of a recent supersonic. This supernova exploded in the Milky Way galaxy more than a hundred years ago.

What leads to Super Nova?

In the event of a change in the nucleus or center of a star occurs. Transformation can be done in two different ways, both of which result in a supernova.

The first type of Super Nova occurs in a binary star system. Binary stars are two stars that revolve around the same orbit. One of these stars (the white carbon-oxygen dwarf) takes matter from its companion star (the Nadim star). Finally, white dwarfs accumulate a lot of material. Having a lot of material causes the star to explode and create a supernova.

The second type of supernova occurs late in the life of a single star. When a star’s nuclear fuel runs out, some of its material flows to the core. Eventually the core becomes so heavy that it can not withstand its gravitational force. The nucleus disintegrates, resulting in a large supernova explosion.

The sun is a star, but its mass is not large enough to lead to a supernova.

Why do scientists study supernovae?

A supernova will only ignite for a short time, but it can tell scientists a lot about the world.

A kind of supernova has shown scientists that we live in a vast world that is growing at an increasing rate. In addition, scientists have determined that supernovae play a major role in the scattering of elements in the universe. When a star explodes, it throws its elements and debris into space. Many of the elements found on Earth are made in the core of stars. These elements form a new star, a planet or whatever is in the universe.

How do NASA scientists look for supernovae?

NASA scientists use different types of telescopes to search for and study supernovae. Some telescopes are used to see visible blast light. Others record information received from X-rays and gamma rays. X-rays were observed by NASA’s Hubble Space Telescope and the Chandra Telescope from the Supernovae. In June 2012, NASA launched the first orbiting telescope to focus light on the energetic region of the electromagnetic spectrum. Nu STAR has several tasks. Must be looking for shattered stars and black holes. Finding the remnants of the superheroes is another task of Nu STAR . Scientists hope to learn more about how stars and elements produced by supernovae explode.

Recognize words

White dwarf

A star that is nearing the end of its life and has used all or most of its nuclear power and has shrunk to the size of Earth.


It is a type of electromagnetic radiation with very short wavelengths and very high energy. X-rays have shorter wavelengths than ultraviolet rays and longer wavelengths than gamma rays.

Gamma ray

The most energetic electromagnetic radiation with the shortest wavelength.
