More space news!

I find it riotously funny that this vertical landing is something that back in the 1960s everyone had this realization that it was bogus and it'd never actually work that way, thus spawning ST:TOS's "beam down" thing and a host of other surface-to-orbit mechanisms in the scifi of the following decades.

I just heard a news report about the brightest supernova ever observed. (Granted, it's about 3 billion LY away.) In fact, it's so bright some astronomers think it can't be a supernova, but something new. I hope for more information.

Astrophysicist have speculated about Hyper-nova.  They usually result from Super-massive stars sometimes called a Hyper Star that burn for less than a million years before going boom.  But these Hyper Stars are through to have existed in the early universe, like the first couple of billions of years.

 

I have not heard of astronomers actually observing a Hyper-Star or a Hyper-nova and 3 billion light years is too close for one. 

 

The wiki on hyper-nova suggests that a hyper-nova could be from something else.

The Economist, of all publications, often has some pretty good space science articles. The Jan. 9-15 issue has a pair of them. The first is about various programs to observe the space around supermassive black holes in unprecedented detail.]'

 

The second concerns a new analysis suggesting the advantages of globular clusters as locations for interstellar civilizations. To wit:

* The stars are all old and past their supernova/gamma-ray burst/other disruptions, so they are relatively safe.

* Even though the stars are close together, "Goldilocks Zone": orbits should be stable and safe from disruption from stellar near-misses.

* Because the stars are so closely packed, interstellar travel and communication is merely difficult instead of insanely, ridiculously difficult.

 

Granted, only one extrasolar planet has been detected in a globular cluster, but the search is early yet.

 

(I tried to copy & paste the url for the globular cluster article, but apparently I have not yet figured out how to do this. Google the Economist and "Cluster Analysis," though, and you should find it.)
