For once we get to talk about a Fermi that is difference than Nvidia’s latest graphics card. Instead, this Fermi is a space-based telescope that observes gamma ray emissions. It is comprised of a Large Area Telescope (LAT) that is mapping the sky in the gamma ray spectrum, and the Gamma-ray Burst Monitor which is looking for gamma-ray bursts.
NASA has just released a set of beautiful images from Fermi of the galaxy Centaurus A. This galaxy is about 11 million light-years away[6] in the constellation Centaurus. The image to the right contains Fermi’s data (in purple), radio data (in orange), and an image in visible light.
“This is something we’ve never seen before in gamma rays,” said Teddy Cheung, a Fermi team member at the Naval Research Laboratory in Washington. “Not only do we see the extended radio lobes, but their gamma-ray output is more than ten times greater than their radio output.” If gamma-ray telescopes had matured before their radio counterparts, astronomers would have instead classified Cen A as a “gamma-ray galaxy.”

I have read your article because the title looked very intersting and made me curious… But I think did not understand the clue of the article 🙁 I think that I am better off with some more women-articles, haha!
