One of these is our Sun, which looks huge to us here on the ground, but is not even one of the biggest in the Milky Way. Spitzer Space Telescope's infrared cameras penetrate much of the dust, revealing the stars of the crowded galactic center region of our Milky Way. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way. 9 Answers. Once a white dwarf forms, it has no way to produce new energy, so it gradually cools. A proper understanding of the formation and evolution of the Milky Way system is crucial for our knowledge of the Universe. And, even more stunningly, it has a galactic bulge , the tightly packed concentration of stars found in the middle of most spiral galaxies. How old is the Milky Way galaxy? But what we can say is it is going to cease being the Milky Way in somewhere between five and seven billion years from now when it merges with the Andromeda Galaxy. Relevance. The milky way consists of 2 x 10^4 kilo of mass.Using the ratio of the mass of the sun will yield 1 trillion average stars.Using the mass of the Universe … I grew up all over in California and especially Northern California, where, in the 90’s we had an amazing view of the Milky Way visiting family up by Paradise. Not only does it measure some 120,000–180,000 light-years in diameter, it is home to planet Earth, the birthplace of humanity. This glow results from a vast sea of cosmic-ray particles slamming into interstellar gas and dust, generating gamma rays.
