Fermi Gamma-ray Space Telescope

Fermi Fridays

Welcome to Fermi Fridays! As we celebrate Fermi's 10 years in space, Friday has become our special day. Every Friday, we'll discuss a topic having to do with the facinating science Fermi is doing, the technology that has been developed to make Fermi more productive, the amazing people that make it all happen, and the many ways that Fermi has inspired others.

We hope you'll check in each week as we unveil a new Fermi Fridays topic. And you can always follow us on social media to get the latest from the Fermi 10-year celebration!

We are keeping an archive of the previous Fermi Fridays in case you've missed any.

December's Topic: Dark Matter

Dark Matter makes up the majority of the mass in the Universe, yet we still don't really know what it is. Fermi is helping us figure it out by searching for gamma-rays from dark matter particles annihilating each other in the most likely locations in the Milky Way and surrounding galaxies.
Although we know can infer how dark matter influences the normal matter it surrounds, detecting dark matter itself is challenging. Dark matter particles should annihilate with each other and produce gamma-rays, therefore we search all the dark places in the gamma-ray sky to see if those photons are hiding in our data.
The best places to look for dark matter are where we don't see much light. Optical surveys have uncovered tens of faint dwarf galaxies surrounding the Milky Way. How do we search for gamma-rays from dark matter in these systems?
The mysteries surrounding dark matter's make up, locations, and properties have inspired creative animations by MICA students and our usual bakers.
