NGC 4388
A field of galaxies in Virgo, the Maiden // Natalie Sigalovsky
From bottom left to top right, the three "main" galaxies are M84, M86, and The Eyes Galaxies (NGC 4438, NGC 4435).
10 billion light-years away...
Giant Star Seen 150 Days Before it Exploded as a Supernova !
In April of 2023, a massive star exploded in NGC 4388, a spiral galaxy about 57 million light-years away. The Zwicky Transient Facility (ZTF) spotted it, and the supernova is called SN 2023 fyg. SN 2023fyq is a rare type of supernova called a Type Ibn.
They show a lack of hydrogen lines and narrow He I emission lines in their spectra. Astronomers think that these characteristics come from the SN interacting with hydrogen-poor, helium-rich circumstellar material (CSM.)
Astronomers only know of a few of these types of SN, so their progenitors are poorly understood. Prior to its explosion, the ZTF also spotted the precursor activity, providing a window into these mysterious progenitors.

NGC 4388 This is an unusual spiral galaxy that has been warped by interactions with surrounding galaxies. Its nestled in the Virgo Cluster, with over 1,300 other galaxies. Some survive the collisions, while others are pulled apart.
NGC 4388, captured by the NASA/ESA Hubble Space Telescope. A member of the Virgo constellation.
