Leftover materials from a star explosion, specifically a supernova, are called supernova remnants. These remnants consist of gas, dust, and heavier elements that are expelled into space during the explosion. Over time, they can contribute to the formation of new stars and planets as they mix with surrounding interstellar material. Notable examples of supernova remnants include the Crab Nebula and the Cassiopeia A.

What is the core of a star left over from a supernova explosion?

The core of a star left over from a supernova explosion is called a neutron star. Neutron stars are incredibly dense, composed mostly of neutrons, and have strong gravitational and magnetic fields. They can be very small in size but contain a mass greater than that of our Sun.

Would it be possible to see the star Betelgeuse even if that star had died hundreds of years ago?

When we look at stars, we are seeing the light that they are emitting. That light could have left them many years ago. The light from Betelgeuse takes over 640 years to reach us. So if it exploded today, we would not see that explosion for over 640 years. So it is possible that it is already gone, but the light that left before it went is still coming towards us.


Did Olympus mons create a big explosion?

Olympus Mons is a large shield volcano on Mars, and it is the tallest volcano in our solar system. It was formed through volcanic activity rather than an explosion. The volcanic activity on Mars is different from explosive eruptions seen on Earth.


What is a star called that a star left at the core of a planetary nebula?

The remnant star left at the core of a planetary nebula is called a white dwarf. After a star like the Sun exhausts its nuclear fuel, it expels its outer layers, forming a planetary nebula, while the hot core remains as a white dwarf. This stellar remnant is primarily composed of carbon and oxygen and gradually cools and dims over time.
