The cooler the white dwarfs in a globular cluster, the older it is. Once a white dwarf forms, it has no way to produce new energy, so it gradually cools. How old is the Milky Way galaxy? The study which describes their findings – titled "The K2-HERMES Survey: age and metallicity of the thick disc" – recently appeared in the Monthly Notices of the Royal Astronomical Society. The radius of the Milky Way is estimated to be around 52.850 light-years. This glow results from a vast sea of cosmic-ray particles slamming into interstellar gas and dust, generating gamma rays. Answer Save. And, even more stunningly, it has a galactic bulge , the tightly packed concentration of stars found in the middle of most spiral galaxies. Spitzer Space Telescope's infrared cameras penetrate much of the dust, revealing the stars of the crowded galactic center region of our Milky Way. The exact number is not known. That’s one way of looking into the past, but in our case we simply look for stars that are already very old—and that’s why we call it stellar archaeology. How old is the Milky Way?

These clouds, called HII regions, are ionized by young, hot stars and are basically free protons and electrons.These are both important marker of spiral arms in other spiral galaxies we see, so mapping them in our own galaxy can give a clue about the spiral nature of the Milky Way. Look out on a clear night, and with no light pollution, and billions of stars form a band of light, which in antiquity was given the name Galaxias by the Ancient Greeks, and Via lactea by educated Romans, both of which have the root in the word “milk”.

Add your answer and earn points. Wow. The Milky Way is among the oldest of galaxies. A proper understanding of the formation and evolution of the Milky Way system is crucial for our knowledge of the Universe. But compared to other galaxies and star clusters The Milky Way is small. The Milky Way contains between 100 and 400 billion stars. It's puny compared to M87, an elliptical galaxy 980,000 light years in diameter. The Milky Way contains at least 100 billion stars and may have up to 400 billion stars. Milky Way Galaxy Not counting transient events such as gamma-ray bursts, the brightest object in the gamma-ray sky is the plane of our Milky Way Galaxy. 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 is somewhat close to what the age of the Universe is (which hovers around 13.7 billion years). 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. Our sun is the nearest of the 600 billion stars in this galaxy, is about 4.56 Billion years old so the milky ways probably older than that too. It turns out that the oldest of the globular clusters surrounding our galaxy are about 13 billion years old, which means the Milky Way must be at least that old.
