Astronotes Armagh Planetarium's Stellar Blog! ... Stars . ... Space Flight . ... Some 13.7 billion years ago, a mere millionth of a second after the Big Bang, the first hydrogen and helium nuclei condensed out of a hot, dense soup of quarks and gluons. ... In the very last few kilometres some of the light was scattered by a myriad of water droplets (containing hydrogen nuclei which had existed almost since the Big Bang) slowly descending through the air following a rainshower. ...
CFITSIO Interface Library CFITSIO is a library of ANSI C routines for reading and writing FITS format data files. ... The CFITSIO library is built on Unix systems by typing: > ./configure [--prefix=/target/installation/path] > make (or 'make shared') > make install (this step is optional) at the operating system prompt. The configure command customizes the Makefile for the particular system, then the `make' command compiles the source files and builds the library. ...
... Bad Astronomy . ... Bitesize Astronomy . ... even the brightest star won't last forever.' ... The pressure and heat are so enormous inside the star's core that hydrogen is fused into helium. ... A star like the Sun has enough hydrogen to keep its fusion fires going for billions of years, but a star like Rigel, a massive star in Orion, burns its hydrogen so fast it may run out in just a few million years. ... The problem is, at this point something bad happens: silicon fuses to iron. ...

Supernovae are simply stars which explode. ... To understand supernovae, we need to understand stars. ... In this stage our Sun will swell up hundreds of times its current size, swallowing the Earth, and glowing hundreds of times brighter than it is now. ... Stars more than 10 times the mass of our sun have much more exciting lives. ... A Type II supernova to be precise. ... Since 1995 two teams have been discovering these objects: Our team, the High-Z SN Search, and the Supernova Cosmology Project. ...
... ARC 3.5m | TripleSpec . ... Fowler sampling, read noise, and minimum integration time . ... The integration time for the slit viewer is adjustable, but 30 seconds represents a maximum practical integration for positioning the source and for guiding. Longer integration times are possible, but the delay between exposures makes guiding and/or positioning the source on the slit tedious. ... Decide on your guider integration time and acquire a frame to serve as the background image with "Expose". ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
