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, [2] 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. It is also a member of the NGC 3190 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [3]

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.

NGC 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away in the constellation Ursa Major. Its name comes from its resemblance to the Pinwheel Galaxy. It has two HII regions named NGC 3180 and NGC 3181.

NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, similar to the distance of M101 in the constellation Ursa Major. Both were once considered to be part of the Local Group, but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.

NGC 3370 (also known as UGC 5887 or Silverado Galaxy) is a spiral galaxy about 82.2 ± 5.9 million light-years (25.2 ± 1.8 megaparsecs) away in the constellation Leo. It is nearly comparable to our Milky Way both in diameter with a D25 isophotal size about 77,300 ly (23.69 kpc) comparing to the Milky Way Galaxy's 87,400 ly (26.8 kpc) diameter, and as well as in mass (1011 M). NGC 3370 exhibits an intricate spiral arm structure surrounding a poorly defined nucleus.

<span class="mw-page-title-main">NGC 2276</span> Galaxy in the constellation Cepheus

NGC 2276 is an intermediate spiral galaxy in the constellation Cepheus. The galaxy lies 120 million light-years away from Earth. NGC 2276 has an asymmetrical appearance, most likely caused by gravitational interactions with its neighbor, elliptical galaxy NGC 2300. One of the many starburst spiral arms contains an intermediate mass black hole with 50,000 times the mass of the Sun, named NGC 2276-3c. NGC 2276-3c has produced two jets: a large-scale radio jet, approximately 2,000 light years long, and an "inner jet" about 6 light years long. The galaxy shows an enhanced rate of star formation that may have been triggered by a collision with a dwarf galaxy, or by the gravitational interaction with its neighbor compressing gas and dust.

NGC 4490, also known as the Cocoon Galaxy, is a barred spiral galaxy in the constellation Canes Venatici. William Herschel discovered it in 1788. It is known to be of the closest interacting/merging galactic system. The galaxy lies at a distance of 25 million light years from Earth making it located in the local universe. It interacts with its smaller companion NGC 4485 and as a result is a starburst galaxy. NGC 4490 and NGC 4485 are collectively known in the Atlas of Peculiar Galaxies as Arp 269. The two galaxies has already made their closest approach and are rushing away from each other. It's been discovered that NGC 4490 has a double nucleus.

<span class="mw-page-title-main">NGC 1964</span> Galaxy in the constellation Lepus

NGC 1964 is a barred spiral galaxy in the constellation Lepus. The galaxy lies 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 1964 is approximately 100,000 light years across. At its center lies a supermassive black hole, with estimated mass 2.5 × 107M. The galaxy features two tightly wound inner spiral arms within a disk with high surface brightness and two outer, more open spiral arms that originate near the inner ring. The outer arms feature few small HII regions.
