These enormous emissions of energy occur when black holes, neutron stars or white dwarfs collide - the galactic mergers take just seconds, but they send out a vast wave of radiation.

But the scientists are confident the object is a pulsar, rather than a regular neutron star, because of its high-energy emission and the fact that it doesn't show up in optical wavelengths.

This involves injecting boron atoms into the cancerous organ, and using a neutron beam to split them into destructive high-energy particles.

Pulsars are a special type of neutron star that rotates rapidly, emitting a beam of high-energy that spins much like the bulb in a lighthouse.

Fermi has been a tremendous success at examining some of the most high-energy processes in the cosmos, publishing a catalogue filled with details of the spinning neutron stars known as pulsars, and a wide array of "active galactic nuclei" - probably supermassive black holes.

It would necessarily be beamed energy of gamma-rays, x-rays, and cosmic rays resulting either from the merger of two neutron stars.

OSI's dual-energy X-ray technology discriminates contraband (explosives, currency, drugs) in luggage, while their thermal neutron analysis does the same for bulk cargo in shipping containers and large trucks, without the need to de-crate.
