Andromeda Galaxy in Red
This is a picture of Andromeda by the Spitzer Space Telescope
The Spitzer Space telescope is strange. To effectively function some parts of the telescope must be close to absolute zero, while others have to be around room temperature. The area that must be kept cool is the cryogenic telescope assembly. This is done using liquid helium. Since this is an infrared telescope, because any infrared rays mess up the data. That is why the inner parts of the telescope must be kept cool. The electronics on the other hand can stay around room temperature. [1][2][3]
Eventually the Andromeda Galaxy will crash into our home galaxy, the Milky Way. This will happen in about 4 billion years. In collisions between galaxies stars only very rarely actually collide. More often than not stars are gravitationally flung around instead. Many change their position within the galaxy and some are thrown out entirely. [4]
Good stuff.
beautiful
Amazing
Picky telescope 😂 but makes amazing photos 👍😄
The Andromeda Galaxy , also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 2.5 million light-years from Earth. It is the nearest major galaxy to the Milky Way and was often referred to as the Great Andromeda Nebula in older texts. It received its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda.
Andromeda is approximately 220,000 light years across, and it is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and other smaller galaxies. Despite earlier findings that suggested that the Milky Way contains more dark matter and could be the largest in the grouping, the 2006 observations by the Spitzer Space Telescope revealed that Andromeda contains one trillion (1012) stars: at least twice the number of stars in the Milky Way, which is estimated to be 200–400 billion. The mass of the Andromeda Galaxy is estimated to be 1.5×1012 solar masses, while the Milky Way is estimated to be 8.5×1011 solar masses.
The Milky Way and Andromeda galaxies are expected to collide in 4.5 billion years, eventually merging to form a giant elliptical galaxy or perhaps a large disc galaxy. The apparent magnitude of the Andromeda Galaxy, at 3.4, is among the brightest of the Messier objects, making it visible to the naked eye on moonless nights,[17] even when viewed from areas with moderate light pollution.
Looks amazing :3
Wonderful post @space-pictures ...so beautiful... I follow you
The Andromeda Galaxy seen in infrared by the Spitzer Space Telescope, one of NASA's four Great Space Observatories; this galaxy is our neighbor and is about 2.5 million light years from earth. (I wonder how many planets this galaxy holds???)
Probably billions of planets there and looks like the universe is infinite so there are infinite civilizations, there must even exist many copies of this planet with copies of everyone of us :P
Amazing picture.
the galaxy has around a trillion stars, but I don't know how many planets each one has on average.
test
k
wtf
srsl tho tf is happening
kkkkkkkkkkkkkkkk
broken af
That red color signifies star were old sometimes link to newborn star
Awesome. How the universe works. Following, Voted and resteemed.
