NGC 2500 is a barred spiral galaxy, about 33 million light years distant, with an apparent magnitude of 12.2. Westerlund 2: Detail 4. [23] A huge starspot larger than the diameter of the sun was detected on its surface in 1999 by astronomers using Doppler imaging. There has been some debate over the years as to whether the Milky Way has two spiral arms or four. Pavo is a constellation in the southern sky whose name is Latin for "peacock".Pavo first appeared on a 35-cm (14 in) diameter celestial globe published in 1598 in Amsterdam by Plancius and Jodocus Hondius and was depicted in Johann Bayer's star atlas Uranometria of 1603, and was likely conceived by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and The vertices of this W will point you to Andromeda. The French astronomer Guillaume Le Gentil discovered this satellite galaxy in 1749. It has a lot of satellite galaxies too.

The Greek astronomer Ptolemy observed it and called it the nebulous mass in the breast of Cancer. Galileo was the first to see in through a telescope in 1609, and Charles Messier added the cluster to his catalogue in 1769. He attributed it to either light absorption within the galaxy or modified dynamics in the outer portions of the spiral and not to the missing matter he had uncovered. This memorable event took place at the Smithsonian Museum of Natural History. Also, he was able to prove that the Milky Way is just one of the billions of galaxies out there. . And even by then, astronomers had given it some interesting descriptions. Cancer contains 10 named stars. The constellation name Cancer is pronounced /knsr/. [1] Covering 132 square degrees and 0.320% of the night sky, Triangulum ranks 78th of the 88 constellations in size. Select the two correct answers. It has an apparent magnitude of 6.1.

Deceptively large at about 10.5 x 1.8, this galaxy may seem like a tempting target after imaging its more famous neighbor, NGC 7331, which lies just a few degrees to the southeast. It is based on data obtained through five filters. 5. (tng in li ngn chn nhng tn hiu di khong ny. It is also called Supernova 1885 after the year it was seen. The Delta Cancrids are the only meteor shower associated with the constellation. Retrieved from https://theplanets.org/andromeda/. The latest data shows that it has four arms, as shown in the artist's illustration below. Messier 32 (M32) is also called NGC 221. Cancer is the faintest of the 12 zodiac constellations. Its estimated age is between 3.2 and 5 billion years. The most probable explanation of the origin of the Andromeda Galaxy involved a merger of protogalaxies. Jacks got amenities youll actually use. Most of the stars that populate this galaxy have red hues. in interstellar gases and stars. Though this is not yet fully proven, simulations show that M32 has had interactions with the bigger Andromeda Galaxy in the past. This is the reason why Venus is the hottest planet.

He called them island universes because they are independent and separate from the Milky Way.

[35] 3C 48 was the first quasar ever to be observed, although its true identity was not uncovered until after that of 3C 273 in 1963.

If proven to be true, this will be the first-ever extragalactic planet to be known. The Andromeda galaxy is the largest in the Local Group, where the Milky Way also belongs. The answer is spiral The form of Andromeda galaxy is a large disks that rotate containing stars and nebulae, characterized by a central region at the core, and a halo of stars and star arrayed below and above the disk, characteristics similar to most spiral galaxies, composed by a bulge, a disk and the halo.

Galaxy mergers can occur when two (or more) galaxies collide. The secondary is poorly known, but calculated to be a yellow-white F-type main-sequence star around 1.4 solar masses.

In fact, it is one of the few distant objects that we can see without using any optical aid. These clouds, called HII regions, are ionized by young, hot stars and are basically free protons and electrons. It is one of the oldest open clusters known.

This discovery was made by a group of researchers headed by Robin Barnard of the Harvard-Smithsonian Center for Astrophysics. Spiral arms are regions of stars that extend from the center of barred and unbarred spiral galaxies.These long, thin regions resemble a spiral and thus give spiral galaxies their name. [11], Three stars make up the long narrow triangle that gives the constellation its name. We refer to the four different types of galaxy as the spiral galaxy, the barred spiral galaxy, the elliptical galaxy and the irregular galaxy. The white stars Beta and Gamma Trianguli, of apparent magnitudes 3.00 and 4.00, respectively, form the base of the triangle and the yellow-white Alpha Trianguli, of magnitude 3.41, the apex.
