Is it true that on an average day on Earth, thousands of supernovas happen some place in the universe?

jeezruss_watters said:so at 1 every 5 years in each, that's 30 billion a year or 82 million a day.

http://www.lbl.gov/Science-Articles/Archive/supernova-search.htmlIn an experiment involving an automated telescope and a sensitive electronic detection system, members of LBL's Automated Supernova Search team have found 20 supernovas, most of them in the last three years. Analysis of the data suggests that supernovas occur at least once every 30 years in galaxies like our own, and maybe even more often. In the past, supernovas were thought to occur in Milky Way-type galaxies no more than once in 100 to 300 years.
A supernova is an astronomical event that occurs when a massive star reaches the end of its life and explodes, releasing an enormous amount of energy and creating a bright, visible explosion.
The frequency of supernovae in the universe is estimated to be about three per century in a galaxy the size of our Milky Way. However, the actual rate may vary depending on the type of galaxy and other factors.
Scientists use various techniques, such as telescopes and satellite observations, to track and study supernovae in different galaxies. They also analyze the light and radiation emitted from supernovae to gather information about their frequency and other characteristics.
No, there are different types of supernovae, including Type I and Type II, which have different characteristics and occur in different types of stars. These differences can also affect their frequency in the universe.
Studying the frequency of supernovae can provide valuable insights into the life cycle of stars, the evolution of galaxies, and the overall structure and expansion of the universe. It can also help us understand the elements and materials that make up our universe.
