NGC 7752 and NGC 7753 are a pair of galaxies approximately 272 million light-years away in the constellation Pegasus.
NGC 7753 is the primary galaxy. It is a barred spiral galaxy with a small nucleus. NGC 7752 is the satellite galaxy of NGC 7753. It is a barred lenticular galaxy that is apparently attached to one of NGC 7753's spiral arms. They resemble the Whirlpool Galaxy (M51A) and its satellite NGC 5195 (M51B).
Supernovae
[edit]The first supernova detected in NGC 7753 was SN 2006A in January 2006.[3] It was followed four months later by SN 2006ch, a Type Ia supernova.[3] In January 2013 another Type Ia supernova, SN 2013Q, was detected, and in August 2015 a Type II supernova, SN 2015ae, was discovered.[3]
