Re: Supernova i Pinweel

Ja den ser rigtigt spændende ud:
an “Instant Cosmic Classic” Supernova skriver Berkley
an ‘Once in a Generation' Supernova kalder  UCSB den

Se: http://www.ia.ucsb.edu/pa/display.aspx?pkey=2550

The PTF survey uses a robotic telescope mounted on the 48-inch Samuel Oschin 
Telescope at Palomar Observatory in Southern California to scan the sky 
nightly. As soon as the observations are taken, the data travels more than 
400 miles to NERSC via the National Science Foundation’s High Performance 
Wireless Research and Education Network and DOE’s Energy Sciences Network 
(ESnet). At NERSC, computers running machine learning algorithms in the 
Real-time Transient Detection Pipeline scan through the data and identify 
events to follow up on. Within hours of identifying PTF 11kly, this 
automated system sent the coordinates to telescopes around the world for 
follow-up observations.

11kly er dermed ikke afstanden, men et løbenummer for det "event" 
copmputerne havde fundet: Dvs. event numemr "kly" i 2011

Slå op på



apod.nasa.gov



for 26 aug.



Den forventes at blive mag. 10 indenfor nogle uger, og er type Ia.



Dens navn undrer mig lidt: PTF 11kly, PTF er det observatorie der opdagede 
den.



11kly burde betyde 11 000 lysår, men galaksen er selvfølgelig flere mio ly 
væk







Venligst
