GCSE Astronomy

I am, but I feel so unprepared

How did it go for you guys, I thought it was a pretty hard paper...

it was nothing like the other past papers, do you think grade boundaries will drop

i didnt have a clue about the Black hole questions and that table was just impossible about the declination and all that

Gravitational microlensing
When the light from a distant object is bent by the gravitational field of a dense area. Black holes are very dense, warping the light of any star or planet behind them.

The table about the circumpolar stars was just about applying logic.
E.g. Star with a declination of -16 at a lattitude of 16S would obviously be directly overhead. So would it ever set?

What did everyone get for 18b? The one about the size of the planet based on the graph?

I put 4500000km because the diameter of the star is 9000000, so since it covers up 50% of the star because only 50% of the light was given out, the diameter of the planet is 9000000/2 which is 4500000

GCSE Astronomy, really?

You guys must go to some amazing posh school. Nice.

Not really - quite a few people do it in my school as an extra GCSE and its just your average run of the mill school.
