Gamma-Ray Bursts
After two satellites discovered gamma-ray bursts in 1967, they have become a popular research subject among scientists. At the beginning, many scientists wondered the sources of gamma-ray bursts. There were a few theories, but none of them failed to explain these explosive phenomena clearly until another observation was found in 1997. A Dutch-Italian satellite observed an afterglow of gamma-ray burst, and this afterglow served as records of short bursts for scientists to study. Recently, most astronomers believe that gamma-ray bursts occur when a colossal star collapses. Other researchers also showed interest on this gamma-ray burst because it may be able to explain periods of extinction in Earth's past and provide clues about the early universe.
This is a summary of an essay. I would really appreciate any recommendation or modification to this passage.

I almost thought I was reading Isaac Asimov!

RecentlyCurrently, most astronomers believe that gamma-ray bursts occur when a colossal star collapses. Other researchers also showed interest on in this gamma-ray burst because it may be able to explain periods of extinction in Earth's past and provide clues about the early universe.[Note: This last sentence is okay if the researchers showed interest in a single burst. If they show interest in gamma-ray bursts in general, it should be changed to reflect this by saying that researchers show interest in gamma-ray bursts -- plural.]

[This is very nicely written. Great work!]
