The accepted mission proposals include capabilities for ultraviolet, X-ray, and gamma ray observations.

NASA revealed the Webb Telescope’s first images of the unseen universe.

Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place.

Astronomers think waves from orbiting pairs of supermassive black holes in distant galaxies are light-years long and have been trying to observe them for decades, and now they’re one step closer thanks to NASA’s Fermi Gamma-ray Space Telescope.

For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy.

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy.
