NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.

The Universe is home to numerous exotic and beautiful phenomena, some of which can generate inconceivable amounts of energy. GLAST will open a new window on this high-energy world. With GLAST, astronomers will have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to search for signals of new fundamental processes that are inaccessible in ground-based accelerators and observatories. GLAST's spectacular high-energy gamma-ray "eyeglasses" will reveal hidden wonders, opening our minds to new possibilities and discoveries, expanding our understanding of the Universe and our place in it.

great video !!!!!!!!!!

@vlatin1: You bring up a few good points and yes nothing can escape the event horizon meaning that the jets are outside of the horizon. The leading hypothesis is that the black hole's gigantic mass distorts space and time around it, twisting magnetic field lines into a coil that propels material outward. So yes, the jets may be electric, but what holds the galaxy together and why things fall into the black hole is gravity. (I work with data from GLAST, now called Fermi LAT)

[vlatin1]

So apparently, astronomers will use GLAST to study how black holes accelerate jets of gas outward at high speeds. Wait a minute, when mathematicians invented these infinitely dense point-masses, we were told that nothing could escape a black hole once it has crossed the event horizon. So how are these magical jets accelerating out of a black hole? I thought gravity was an attractive force. Hey NASA, you know what, we live in an Electric Universe, not a gravitational universe.

i have the means to watch a electron force that splits into a beam and a ray.youll be surprised of the outcome

[chris661133]

thanks for that

[RarewareLover]

59-1:01 are from a the Duracell commercials

[Triphylla]

the universe is pure awesome

[SpanerMagnet]

indeed it is

[classicsfreestyle]

the universe is pure energy
