NGC 2442 and NGC 2443

NGC 2442 and NGC 2443 are two parts of a single intermediate spiral galaxy, commonly known as the Meathook Galaxy or the Cobra and Mouse. It is about 50 million light-years away in the constellation Volans. It was discovered by Sir John Herschel on December 23, 1834 during his survey of southern skies with a 18.25 inch diameter reflecting telescope from an observatory he set up in Cape Town, South Africa. Associated with this galaxy is HIPASS J0731-69, a cloud of gas devoid of any stars. It is likely that the cloud was torn loose from NGC 2442 by a companion.

Supernovae
Three, or perhaps four, supernovae have been observed in NGC 2442: • SN 1999ga (Type II, mag. 18) was discovered by the Perth Astronomical Research Group on 19 November 1999. • SN 2015F (Type Ia, mag. 16.8) was discovered by on 9 March 2015. It reached magnitude 12.9, making it the brightest supernova of 2015. • Gaia16cfr, also known as AT 2016jbu, was a supernova imposter that was discovered in NGC 2442 on 1 December 2016. It reached a Gaia apparent magnitude of 19.3 and absolute magnitude of about −12. However, a paper published in August 2022 suggested that this was a genuine, but strange, supernova. • SN 2026etu (Type Ia, mag. 18.547) was discovered by ATLAS on 1 March 2026. == References ==
