How many stars does NGC 6872 have?

It contains anywhere between 500 billion to 2 trillion stars. The Condor Galaxy contains a large number of star clusters. Most of the young clusters in the galaxy are less than 100 million years old and lie in the outer region of the galactic disk, in the tidal tails.

Who discovered NGC 6872?

astronomer John Herschel
The galaxy has two elongated arms; from tip to tip, NGC 6872 measures over 522,000 light-years (160,000 pc), making it one of the largest known spiral galaxies. It was discovered on 27 June 1835 by English astronomer John Herschel.

Is NGC 253 a spiral galaxy?

NGC 253 is one of the brightest spiral galaxies visible, but also one of the dustiest. 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.

What are the three main components of the spiral galaxy?

The three components are the disk (there is a thin and a thick disk), bulge and halo.

What is the name of the largest spiral galaxy?

Astronomers have crowned the universe’s largest known spiral galaxy, a spectacular behemoth five times bigger than our own Milky Way. The title-holder is now NGC 6872, a barred spiral found 212 million light-years away in the southern constellation Pavo, researchers announced today (Jan.

What is the largest known spiral galaxy?

galaxy NGC 6872
The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. This enormous spiral is 522,000 light-years across from the tip of one outstretched arm to the tip of the other, making it about five times the size of our home galaxy, the Milky Way.

What type of galaxy is NGC 2685?

polar ring galaxy
Explanation: NGC 2685 is a confirmed polar ring galaxy – a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the plane of a flat galactic disk.

What are the 2 types of spiral galaxies?

Spiral galaxies appear as flat, blue-white disks of stars, gas and dust with yellowish bulges in their centers. These galaxies are divided into two groups: normal spirals and barred spirals. In barred spirals, the bar of stars runs through the central bulge.
