A supernova ejects a variety of materials into space, including heavy elements such as iron, nickel, and even lighter elements like hydrogen and helium. These materials are produced during the nuclear fusion processes in the star's core and are released into the interstellar medium when the star explodes. This dispersal enriches the surrounding space with elements necessary for the formation of new stars, planets, and ultimately, life.
The material sent into space by a supernova is called supernova ejecta. It includes elements such as hydrogen, helium, carbon, oxygen, and heavier elements created during the supernova explosion.
An interstellar cloud.
Remember that Supernovas are great contributors to interstellar material that forms new stars. The star which explodes to supernova will leave either a pulsar or a black hole depending on its mass. Part of the supernova will scatter into space.
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
Much, if not all of the material that makes up the star is expelled at extremely high speeds (up to 30,000 Km/s). The shockwave from this explosion destroys any planets or other stellar bodies within its region of influence. The shockwave also pushes all the gas and dust surrounding the star into a vast, roughly sphereical cloud, for example, 'Kepler's supernova remnant sn 1604'. This accumulation of gas and dust can can result in the growth of new stars as the gas and dust clumps together. The expelled material contains many higher mass elements such as nickel, cobalt and silicon and the material is the main source of elements heavier than oxygen which is the 8th element out of over 100 in the periodic table.

Supernova
Remember that Supernovas are great contributors to interstellar material that forms new stars. The star which explodes to supernova will leave either a pulsar or a black hole depending on its mass. Part of the supernova will scatter into space.
If enough mass is left over after the supernova explosion, i.e. after material is blown off into space, the star will become a black hole. Less massive stars will become neutron stars. A neutron star can convert to a black hole later, if enough matter falls into it.
Canada has never sent a Space Shuttle into space.
A small amount might get out with solar (or stellar) wind. But mainly, at the end of the life of larger stars, there is a violent explosion called a supernova, that ejects a large part of the star's material into space.
Yes, that is why all space craft are constructed in clean rooms prior to being sent to other planets

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.
