No, it is NOT a star! Several orders of magnitudes far from being a star actually. I am talking about quasars (quasi-stellar radio source) - often being described as distant stars. Oh, astronomers pain.


All men and women to the atlases!
I experienced the highest density of colleagues with background from astrophysics when I worked at the Norwegian Mapping Authority. Mapping seems like an earthly matter, per definition, but it never was and never will be. First of all our planet Earth is exactly that - a planet! So I say as an astrophysicist I do not discriminate against any of the planets, including planet Earth! Right now I focus almost entirely on this particular planet.
Our Earth observation capacity is growing. Not only are star satellite data providers such as NASA and ESA improving their high quality products, new economies such as China and Brazil invest parts of their new won wealth in remote sensing as well.
This is not a rainforest!

A story wherein I reveal resistant and deliberate ignorance.
Everytime I hear the word 'manhole' I think I have a hearing problem, or that my English is really, really bad. It sounds like a word I should understand, consisting of the two well known words 'man' and 'hole' , both of which give perfect meaning.

It is too ambiguous for that; a hole made for a man? or by a man? maybe even a certain hole in a man? For those of you who share my resistant linguistic ignorance, here is a picture showing what a manhole really is – so we all know what we are talking about in the continuing.
