The Gamma Ray Sky - March 21st, 1998.

"What if you could "see" gamma rays? If you could, the sky would seem to be filled with a shimmering high-energy glow from the most exotic and mysterious objects in the Universe. In the early 1990s, NASA's orbiting Compton Observatory produced this premier vista of the entire sky in gamma rays - photons with more than 40 million times the energy of visible light. The diffuse gamma-ray glow from the plane of our Milky Way galaxy runs horizontally through the false-colour image. The brightest spots in the galactic plane (right of center) are pulsars - spinning magnetised neutron stars formed in the violent crucibles of stellar explosions. Above and below the plane, quasars, believed to be powered by supermassive black holes, produce gamma-ray beacons at the edges of the Universe."

I just hit a huge milestone designing my giant pinball machine in Minecraft: the playfield is all laid out!

I'm calling the game Deep Field, and there's five primary objectives based on hitting different shots representing bands of the electromagnetic spectrum.

IR: rollover switches Visible light: pop bumpers UV: captive ball X-rays: Drop targets Gamma rays: spinner

Also, a kinetic sling disc to light locks for Pluto Multiball!

“GN-z11 flash” !

Long gamma-ray bursts (GRB), explosions of very massive stars, provide crucial information on stellar and galaxy evolution, even at redshifts z ~ 8 - 9.5, when the Universe was only 500-600 million years old.

During observations of a galaxy at a redshift of z ~ 11 (400 million years after the Big Bang), a bright signal, named GN-z11-flash, shorter than 245 s was detected and interpreted as an ultraviolet flash associated with a GRB in this galaxy, or a shock-breakout in a Population III supernova.

Its resulting luminosity would be consistent with that of other GRBs, but a discussion based on probability arguments started on whether this is instead a signal from a man-made satellite or a Solar System object.

Here we show a conclusive association of GN-z11-flash with Breeze-M upper stage of a Russian Proton rocket on a highly elliptical orbit.

This rules out GN-z11-flash as the most distant GRB ever detected. It also implies that monitoring of a larger sample of very high redshift galaxies is needed to detect such distant GRBs. This also highlights the importance of a complete database of Earth satellites and debris, which can allow proper interpretation of astronomical observations.

Seeing in Gamma Rays, by Fermi.

The gamma ray map of the sky looks like fascinating, the shape you see is that of our own galaxy, the Milky Way, and as you move in towards the centre, there's a concentration of Pulsars, old dead stars still beaming out gamma radiation, but look closer and you can see a number of objects not in the galactic plane.

Many of these are far off galaxies themselves, but a few don't correspond to any known object, at least currently mapped, and are the subject of much ongoing research.
