English: This animation depicts the collision between our Milky Way galaxy and the Andromeda galaxy. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now. Around 6 billion years from now, the two galaxies will merge to form a single galaxy.
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galaxy, which are so far away that they cannot be individually distinguished by the naked eye.
To some astronomers, the galaxy looks like a penguin or a porpoise. [5] NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet". On 20 June 2013, the Hubble Space Telescope examined and photographed NGC 2936. [5] NGC 2936 once had a flat, spiral disk. The orbits of the ...
Astronomers using the James Webb Space Telescope have spied dynamic flares of light near the supermassive black hole at the center of the Milky Way galaxy. The constant, rapid-fire display ...
NGC 891 looks as the Milky Way would look like when viewed edge-on (some astronomers have even noted how similar to NGC 891 our galaxy looks as seen from the Southern Hemisphere [9]) and, in fact, both galaxies are considered very similar in terms of luminosity and size; [10] studies of the dynamics of its molecular hydrogen have also proven the likely presence of a central bar.

The months of July and August are the best time of the year to see the Milky Way without a telescope, according to LiveScience, a popular science website. The Milky Way galaxy consists of several ...
Hubble Space Telescope image showing part of the Norma cluster, including ESO 137-002. The Great Attractor is a region of gravitational attraction in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster of galaxies that includes the Milky Way galaxy, as well as about 100,000 other galaxies.
Messier 99 or M99, also known as NGC 4254 or St. Catherine's Wheel, is a grand design spiral galaxy in the northern constellation Coma Berenices approximately 15,000,000 parsecs (49,000,000 light-years) from the Milky Way. [5] It was discovered by Pierre Méchain on 17 March 1781.
