The different types of supernovae explained - Astronomy Magazine
2023年11月8日 · Differences in progenitor stars and the mechanisms of their explosions produce different types of supernovae, with each leaving behind a unique spectral fingerprint. And understanding these...
Supernova - Wikipedia
Supernovae are a major source of elements in the interstellar medium from oxygen to rubidium. The expanding shock waves of supernovae can trigger the formation of new stars. Supernovae are a major source of cosmic rays. They might also produce gravitational waves.

2025年1月17日 · Types of supernovae. Supernovae may be divided into two broad classes, Type I and Type II, according to the way in which they detonate. Type I supernovae may be up to three times brighter than Type II; they also differ from Type II supernovae in that their spectra contain no hydrogen lines and they expand about twice as rapidly. Type II supernovae

What is a Supernova? This is the biggest explosion that will ever light up the modern universe. Every blast is the extremely bright, super-powerful explosion of a star. Supernovas are so bright that they can be seen across the universe, outshining their entire galaxies for a few days or even months. How Rare is a Supernova?
What are the different kinds of supernovae? - Phys.org
2016年3月15日 · There are two main types of supernovae, the Type I and the Type II. I know this sounds a little counter intuitive, but let's start with the Type II first.
What is a supernova? | Space
2023年6月19日 · A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or...
Sensing the Dynamic Universe: Supernovae - Harvard University
Supernovae can first be divided into two major classes: type 1 or type 2. Type 1 supernovae contain no signs of hydrogen, while type 2 supernovae do. Hydrogen can be detected at specific wavelengths in the spectrum where hydrogen signatures are either visible or not.
Nova, Supernova, Hypernova, Kilonova – What’s The Difference?
2023年9月29日 · Supernovas are not just slightly brighter versions of novas, they’re the result of one of two processes, each distinct from those that cause nova. Moreover, their intrinsic brightness differs by...
Types of Supernovae - How a Supernova Works - HowStuffWorks
Stars that have enough heft to go out with a bang are separated into two supernova classes -- Type I and Type II. Astronomer Rudolph Minkowski laid out these classifications in 1941. Astronomers learn a lot about stars from the colors of light that they emit.
Supernovas & Remnants - Harvard–Smithsonian Center for …
Today, astronomers distinguish two types of supernova: those involving white dwarfs, and those that are the explosions of very massive stars. Both types are responsible for creating and spreading new elements through space, which are the chemical building blocks for the next generation of stars and planets.
