Chapter 20: Problem 66

Search the World Wide Web for information about SN 1994I, a supernova that occurred in the galaxy M.51 (NGC 5194). Why was this supernova unusual? Was it bright enough to have been seen by amateur astronomers?

Short Answer

Expert verified

Supernova SN 1994I, set off in the galaxy M.51, was unusual because it was classified as a Type Ic supernova, which is characterized by the absence of hydrogen and helium lines and strong silicon lines in the spectrum. Its peak brightness would depend on information found, but if its magnitude was less than +6, it should have been visible to amateur astronomers.

Step by step solution

Information Retrieval

Perform a detailed search in reliable astronomy and science websites, journals, and resources about supernova SN 1994I. Accumulate all the relevant data including its characteristics, location and other important details.

Identify the Unusual Characteristics

With the gathered information, identify what made SN 1994I unusual compared to other supernovas. This could be related to its spectral characteristics, the type of its explosion, its composition or any other distinguishing feature.

Assess the Brightness of SN 1994I

Lastly, locate the information regarding the magnitude of brightness of SN 1994I at its peak. Use this information to determine if the light from this supernova could have been visible to amateur astronomers on earth. This is usually determined by comparing its apparent magnitude to the standard value that can be observed with the naked eye.
