Maanvinder Pilania - Fermi Bubbles of the Milky Way Galaxy

In 2010, gamma ray observations by NASA’s Fermi Space Telescope revealed an unknown mysterious structure of our home galaxy Milky Way. Astronomers discovered two giant bubbles that emerge below and above the center of our galaxy. They are known as Fermi Bubbles. Each bubble is about 25000 light years long, spanning a total length of about 50,000 light years. The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old.   Further Reading: https://fermi.gsfc.nasa.gov/science/constellations/pages/bubbles.html https://www.nasa.gov/mission_pages/GLAST/news/new-structure.html   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
