Is sculptor a galaxy?
The Sculptor Galaxy, also known as NGC 253 or the Silver Dollar Galaxy, is one of the brightest galaxies visible in the night sky and is located 13 million lightyears away.
How many stars are in the galaxy Sculptor?
Sculptor has six stars with known exoplanets, HD 4208 (spectral class G7V), HD 4113 (G5V), HD 9578 (G1V), WASP-8 (G6), WASP-29 (K4V) and WASP-45 (K2V). The constellation does not contain any Messier objects and is not associated with any meteor showers.
How did the Sculptor Galaxy form?
This, along with other peculiarities found in NGC 253, suggest that a gas-rich dwarf galaxy collided with it 200 million years ago, disturbing its disk and starting the present starburst.
How big is NGC 253?
45,000 light yearsSculptor Galaxy / Radius
About 70 thousand light-years across, NGC 253, pictured, is the largest member of the Sculptor Group of Galaxies, the nearest to our own Local Group of galaxies.
How old is the Sculptor Galaxy?
We have estimated an age of 15 ± 2 Gyr for the bulk of the main‐sequence stars. This age is comparable to the ages of the oldest Galactic globular clusters.
What are 4 constellations in the Milky Way galaxy?
In the northern hemisphere, the major constellations the Milky Way passes through includes Orion, Auriga, Perseus, Cassiopeia, Sagittarius, and Scorpius; whilst in the Southern Hemisphere these include Norma, Circinus, Crux, and Carina.
How far is NGC 253 from us?
11.42 million light yearsSculptor Galaxy / Distance to Earth
Are all 88 constellations in the Milky Way?
It is important to make this distinction, because otherwise we would say that all the stars and 88 recognized constellations we can see with the naked eye are contained within our own galaxy, and are therefore a part of our own Milky Way.
How many galaxies are they?
While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.
What type of galaxy is NGC 253?
NGC 253 is one of the brightest spiral galaxies visible, but also one of the dustiest. Dubbed the Silver Coin for its appearance in smalltelescopes, it is more formally known as the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor.
What galaxies are in sculptor?
Other deep sky objects in Sculptor include the lenticular galaxies NGC 314, NGC 254, NGC 264, NGC 148, and the NGC 526 pair, and the spiral galaxies NGC 115, NGC 131, NGC 150, NGC 289, NGC 174, NGC 334, and NGC 365.
What is the Sculptor Group in the Milky Way?
Credit: 2MASS. The Sculptor Group is a loose group of galaxies visible near the south galactic pole. The group is one of the closest groups of galaxies to the Local Group; the distance to the center of the group from the Milky Way is approximately 3.9 Mpc (12.7 Mly ).
What is the Sculptor Group?
The Sculptor Group is a loose group of galaxies visible near the south galactic pole. The group is one of the closest groups of galaxies to the Local Group; the distance to the center of the group from the Milky Way is approximately 3.9 Mpc (12.7 Mly).
How do you observe the Sculptor Galaxy?
Amateur observation. As one of the brightest galaxies in the sky, the Sculptor Galaxy can be seen through binoculars and is near the star Beta Ceti. It is considered one of the most easily viewed galaxies in the sky after the Andromeda Galaxy. The Sculptor Galaxy is a good target for observation with a telescope with a 300 mm diameter or larger.
