Our sun is not a first generation star, so the gases and other materials that clumped together to form our solar system came from the remains of the previous generation. There is no telling how many supernovas contributed to the materials that make our system (and us) up, but the number is very large; possibly in the millions. Scientists may have ways to estimate the number, but we will never really know.
For a few days, the supernova will shine about as bright as an entire galaxy - as bright as 100 billion suns.
The light from a supernova that occurs within 50 light years would likely be enough to sterilize the earth through intense UV radiation.
On average, supernovae are observed about once per century. Fortunately, there have not been any especially close to our solar system.
Interesting fluctuations in the brightness and apparent diameter of the star Betelgeuse (the red supergiant at the shoulder of the constellation Orion) have caused some astronomers to believe that Betelgeuse may be about to go supernova, any century now. Betelgeuse is about 640 light years away; we wouldn't want to see a supernova any closer!
If Betelgeuse were to go supernova, it would probably be brighter than the full Moon, easily visible in broad daylight probably for the next year.

Only one space shuttle exploded during takeoff. That shuttle was the Challenger, which exploded on January 28, 1986. The only other space shuttle to be destroyed was the Columbia, which disintegrated on reentry on February 1, 2003.
Two space shuttles exploded; one upon take off and one on re-entry. The Space Shuttle Challenger exploded in 1986, 1 minute 13 seconds after take-off killing all seven members on board. The Space Shuttle Columbia exploded on re-entry in 2003 also killing all seven members on board.
A supernova is a star which has effectively exploded. There have been many in our galaxy which we call the Milky Way. There have also been supernovas in other galaxies too.
Exploded star dust. Everything on earth was once part of a star that exploded. You probably want to know what chemicals. Mostly the same thing as people; water, carbon, many trace compounds and elements.

You can get an exploded view of most transmissions from the transmission manufacturer. Many auto-parts stores will provide an exploded view of transmissions.
There have been about 15 observed supernovas [See Link] from as far away as Australia China, Europe, America. As many are visible to the naked eye, I would say that all countries have observed them, whether or not they has been recorded.

We do not yet have enough experimental data to answer the question precisely, but there have been about one per century in the Milky Way (at least, the part that we can see). We know that there are supernovas in other galaxies, but they are detectable only through large telescopes.
It gets so many Earth Quakes because it is under a fault line. Plates under the Earth's surface rub against each other and create Earth Quakes.
Advancements in technology, globalization, and the increasing interconnectedness of the world have all contributed to the expansion of geography into different fields such as GIS, remote sensing, and environmental studies. The interdisciplinary nature of geography also allows for its application in various sectors, leading to its growth in different directions. Ultimately, the diverse and evolving nature of the discipline has driven its expansion into multiple areas.

As both atomic bombs and supernovas vary in yield, this question has no single answer.
