Encyclopedia
NGC 3190 is a spiral galaxy
with tightly wound arms and lying in the constellation
Leo
. It was discovered by William Herschel
in 1784. NGC 3190 is member of Hickson 44 galaxy group, estimated at around 80 million light years away, and consisting of four galaxies in a tight group - NGC 3193 is fairly featureless, NGC 3187 is a dim but striking spiral galaxy and NGC 3185 has a barred spiral structure with an outer ring.
In 2002 two supernovae were observed in the galaxy. A Brazilian amateur astronomer (Paulo Cacella) detected one supernova in the southeastern part in March 2002 (SN 2002bo), and then an Italian team, while studying the first one, detected a second supernova (SN 2002cv) on the other side two months later.
