2016年3月28日 · Known as UGC 4459, this dwarf galaxy is located approximately 11 million light-years away in the constellation of Ursa Major (The Great Bear), a constellation that is also home to the Pinwheel Galaxy (M101), the Owl Nebula (M97), Messier 81, Messier 82 and several other galaxies all part of the M81 group.

2016年4月1日 · UGC 4459’s diffused and disorganized appearance is characteristic of an irregular dwarf galaxy. Lacking a distinctive structure or shape, irregular dwarf galaxies are often chaotic in appearance, with neither a nuclear bulge — a huge, tightly packed central group of stars — nor any trace of spiral arms — regions of stars extending from ...

2023年9月11日 · Known as UGC 4459, this dwarf galaxy is located approximately 11 million light-years away in the constellation of Ursa Major (The Great Bear).

NGC 4459 is a lenticular galaxy located about 50 million light-years away [2] in the constellation of Coma Berenices. [3] NGC 4459 is also classified as a LINER galaxy. [2] NGC 4459 was discovered by astronomer William Herschel on January 14, 1787. [4] NGC 4459 is a member of the Virgo Cluster. [5]

2016年3月28日 · UGC 4459, otherwise known as LEDA 24050, DDO 53 and VV 499, is a small galaxy with a visual magnitude of 13.7. It is located in the constellation Ursa Major, approximately 12 million light-years away.

2016年3月28日 · This newly released Hubble image shows dwarf galaxy UGC 4459, which is located approximately 11 million light-years away. Despite being less famous than their elliptical and spiral galactic cousins, irregular dwarf galaxies, such as the one captured in this NASA/ESA Hubble Space Telescope image,

2016年4月17日 · Known as UGC 4459, this dwarf galaxy is located approximately 11 million light-years away in the constellation of Ursa Major (The Great Bear), a constellation that is also home to the Pinwheel Galaxy (M101), the Owl Nebula (M97), Messier 81, Messier 82 and several other galaxies all part of the M81 group.

2016年3月28日 · In this Hubble Space Telescope image we see an irregular dwarf galaxy known as UGC 4459, located in the constellation of Ursa Major (The Great Bear). While UGC 4459’s diffused and disorganised stellar population of several billion sounds impressive, this is small when compared to the 200 to 300 billion stars in the Milky Way.
