Supernova SN 2025bvm in the NGC 4156 galaxy: an image – 30 Mar. 2025.
Here we present supernova SN 2025bvm in the nice spiral galaxy NGC 4156, with the stunning galaxy NGC 4151 in the same field of view.
Supernova SN 2025bvm in the NGC 4156 galaxy: 30 Mar. 2025.
The image above comes from the average of 5, 120-second, unguided exposures, unfiltered, remotely taken with the “Elena” (PlaneWave 17″ + Paramount MEII + SBIG STL-6303E) robotic unit available as part of the Virtual Telescope Project in Manciano, Italy. The supernova is indicated by an arrow in the upper left insert.
We estimated SN 2025bvm as bright as mag. 16.4 (R-mags for the reference stars from the Gaia DR2 star catalogue). SN 2025bvm was discovered on 17 Feb. 2025 and it is a type Ia supernova.
The host galaxy is NGC 4156, a barred spiral galaxy hosting an active galactic nucleus (AGN) with a supermassive black hole and it is located at about 300 million light years from us. On the upper right, the spiral galaxy NGC 4151 is visible, placed at about 50 million of light years from the Earth. NGC 4151 is also an active galaxy (AGN)
