| 説明 | NGC 4762 is an edge-on galaxy in the constellation Virgo. It is at a distance of 60 million light-years and is a member of the Virgo Cluster of galaxies.Previously thought to be a barred spiral galaxy, NGC 4762 has since been found to be a lenticular galaxy, a kind of intermediate step between an elliptical and a spiral. The edge-on view of this peculiar galaxy makes it difficult to determine its true shape, but astronomers have found the galaxy to consist of four main components — a central bulge, a bar, a thick disk, and an outer ring. The galaxy's disk is asymmetric and warped, which could potentially be explained by NGC 4762 colliding with a smaller galaxy in the past. The remains of this former companion may then have settled within NGC 4762's disk, redistributing the gas and stars and changing the disk's morphology. NGC 4762 also contains a highly energetic nucleus.For more information, visit: www.spacetelescope.org/images/potw1443a/Credit: ESA/Hubble & NASAFind us on Twitter, Instagram, Facebook and YouTube |
