A new supernova in Virgo
Steven Bellavia e-mailed EarthSky on Thursday, February 8, 2024, to alert us about a new supernova explosion in a galaxy some 55 million light-years away. From across vast space and time, the supernova shows up remarkably easily in his image.
Amateur astronomer Koichi Itagaki of Japan discovered the supernova on January 4, 2024. Itagaki has discovered more than 170 supernovas. When Itagaki discovered it, the supernova was still a remarkably dim magnitude 16.3. The supernova, now named SN 2024gy, has brightened a bit since then.
When Steven took his image of the supernova on February 8, it was approximately magnitude 13. But that’s still far below what most casual amateur astronomers can spy with a backyard telescope.
In the image above, the “before” of galaxy NGC 4216 is from May 31, 2022. And Steven took the “after” image on February 8, 2024.
Here are the still images of the galaxy, in case you want to take some time to pore over both the before and after moments that Steven captured.
Bottom line: Steven Bellavia caught before and after images of galaxy NGC 4216, which is currently hosting a new supernova.
