The Fermi Bubbles emit higher-energy gamma rays than the rest of the galaxys disk. The bubbles may be related to the release of vast amounts of energy emitted from the supermassive black hole at the center of our Milky Way galaxy.
How long are the Fermi bubbles?
about 50,000 light-years From tip to tip, the bubbles stretch about 50,000 light-years across (thats about half the diameter of the Milky Way itself), yet are visible only in high-energy gamma-ray light.
What creates heat bubbles in the Milky Way?
The kind of energy that can spread hot gas to a distance of over 25,000 light-years doesnt come easily to a typical galaxy. Or perhaps a star wandered too close to Sag A* and was ripped to shreds, releasing all that potent gravitational energy in a single violent episode, leading to the formation of the bubbles.
Is Fermi still in space?
Fermi was designed to last five to 10 years. The mission passed its 10th anniversary in June 2018 and was still operational as of mid-2018, although it is expected to end operations in fall 2018.
What types of processes can emit gamma rays quizlet?
What types of processes can emit gamma-rays? Gamma rays are produced during incredibly energetic events, such as near-lightspeed collisions of particles. Matter is converted into energy during matter-antimatter collisions.
What are Fermi bubbles made of?
Fermi bubbles are two colossal blobs filled with very hot gas, cosmic rays and magnetic fields.
Who discovered Fermi bubbles?
Slatyer, an MIT physicist originally from Australia, is most famous as a co-discoverer of the Fermi Bubbles. While looking for hints of dark matters signature in the gamma rays emanating from the center of the Milky Way, she and her colleagues found never-before-seen structures extending far above and below the ...
Who owns the Fermi telescope?
NASA Fermi was launched on 11 June 2008 at 16:05 UTC aboard a Delta II 7920-H rocket. The mission is a joint venture of NASA, the United States Department of Energy, and government agencies in France, Germany, Italy, Japan, and Sweden, becoming the most sensitive gamma-ray telescope on orbit, succeeding INTEGRAL.

What types of processes can emit gamma rays?
Gamma rays are produced primarily by four different nuclear reactions: fusion, fission, alpha decay and gamma decay. Nuclear fusion is the reaction that powers the sun and stars.
When did the Fermi bubbles form?
2010 Extending 25,000 light years both above and below the center of the Milky Way, the Fermi Bubbles were discovered in 2010 by the Fermi Gamma Ray Telescope. These faint but highly energetic outflows of gas are racing away from the center of the Milky Way at millions of miles per hour.
Which types of radiation give us the best view of the center of the Milky Way?
X-ray. In the Milky Way, we see X-rays from hot gas, binary star systems, young stars and stellar clusters, supernova remnants, and matter falling into our galaxys central black hole.
Is Fermi telescope still operating?
After five years of operations, on Aug. 11, 2013, Fermi entered an extended phase of its mission, a deeper study of the high-energy cosmos. This is a significant step toward the science teams planned goal of a decade of observations, ending in 2018.
Which kind of star is most likely to be found in the halo?
Old stars with few heavy elements are referred to as population II stars and are found in the halo and in globular clusters. Population I stars contain more heavy elements than globular cluster and halo stars, are typically younger and found in the disk, and are especially concentrated in the spiral arms.
Where in the Milky Way would you be most likely to find an ionization nebula?
Where would you be most likely to find an ionization nebula? the orbits of stars in the galactic center.
Can gamma rays make you Hulk?
The gamma rays mutate Bruce Banners DNA and cause him to transform into The Hulk whenever hes angry.
How fast are gamma rays?
In a vacuum, all forms of electromagnetic radiation—whether microwaves, visible light, or gamma rays—travel at the speed of light (c), which is the speed with which all forms of electromagnetic radiation travel in a vacuum, a fundamental physical constant with a value of 2.99792458 × 108 m/s (which is about 3.00 ×108 m ...
What types of radiation do we not see from the center of the Milky Way?
Infrared. Infrared light does not get absorbed as easily as optical light, so infrared observations peer farther into the plane of the Milky Way than optical telescopes.
Where in the Milky Way would we look to find lots of gas and dust?
At the center of the galaxy is the galactic bulge. The heart of the Milky Way is crammed full of gas, dust, and stars. The bulge is the reason that you can only see a small percentage of the total stars in the galaxy.
How old is our Galaxy?
13.51 billion years Milky Way/Age Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.
