NGC 7541 is a barred spiral galaxy located around 104 million light-years away in the constellation Pisces. [1] It was discovered in 1785 by William Herschel, and it is 106,000 light-years across. [2] NGC 7541 is known to have lots of star-forming regions. [1]

Characteristics

NGC 7541, like other barred spiral galaxies, has a bar in the center of it. [2] The bar cuts through the center of the galaxy, and into the other side. [3] This type of galaxy is known as "grand design". [1] NGC 7541 is actually observed to have a higher-than-usual star formation rate, adding weight to the theory that spiral bars act as stellar nurseries, corralling and funneling inwards the material and fuel needed to create and nurture new baby stars. [3] NGC 7541 also has an active galactic nuclei, as shown in the HST image. [3] [4]

NGC 7541 forms a pair with NGC 7537, a spiral galaxy 127 million light-years away, next to NGC 7541. [4] [5] The two galaxies have shown some signs of interaction, as two tidal tails form out of NGC 7541. [3]

NGC 7742 also known as Fried Egg Galaxy is a face-on unbarred spiral galaxy in the constellation Pegasus. Its velocity with respect to the cosmic microwave background is 1292 ± 26 km/s, which corresponds to a Hubble distance of 62.2 ± 4.5 Mly (19.06 ± 1.39 Mpc). In addition, six non-redshift measurements give a farther distance of 84.09 ± 26.51 Mly (25.783 ± 8.129 Mpc). It was discovered by German-British astronomer William Herschel on 18 Oct 1784.

Messier 61 is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779, six days before Charles Messier discovered the same galaxy. Messier had observed it on the same night as Oriani but had mistaken it for a comet. Its distance has been estimated to be 45.61 million light years from the Milky Way Galaxy. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.

NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC 7335, NGC 7336, NGC 7337 and NGC 7340, lie far in the background at distances of approximately 300–350 million light years.

<span class="mw-page-title-main">NGC 7479</span> Galaxy in the constellation Pegasus

NGC 7479 is a barred spiral galaxy about 105 million light-years away in the constellation Pegasus. William Herschel discovered it in 1784. NGC 7479 is also recognized as a Seyfert galaxy and a LINER undergoing starburst activity not only on the nucleus and the outer arms, but also across the bar of the galaxy, where most of the stars were formed in the last 100 million years. Polarization studies of this galaxy indicate that it recently underwent a minor merger and that it is unique in the radio continuum, with arms opening in a direction opposite to the optical arms. This feature, along with the asymmetrical arms of the galaxy and the intense star formation activity are attributed to a merger with a smaller galaxy. This galaxy is similar in both size and morphology to the barred spiral NGC 1300.

NGC 3938 is an unbarred spiral galaxy in the Ursa Major constellation. It was discovered on 6 February 1788 by William Herschel. It is one of the brightest spiral galaxies in the Ursa Major South galaxy group and is roughly 67,000 light years in diameter. It is approximately 43 million light years away from Earth.

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.
