Exoplanet observation by imagination

By |2020-01-21T20:38:03+00:0021 January 2020|Categories: Exoplanet, News|

How do you observe Exoplanets when it’s cloudy? By imagination. I’m not an artist but I can use Photoshop, so here’s an Exoplanet “observation” by imagination. Just a bit of fun – and really not to scale – that would be boring!

FORTH-1b is the one closest to the star, far too hot for water and life, but FORTH-1c is in the Goldilocks zone, is about 1.2 times the Earth’s diameter and has a satellite. There are 2 gas giants further out.

Heart of the Rosette NGC2244

By |2020-02-06T17:57:40+00:006 February 2020|Categories: HOYS, Nebula, News|

Data taken for the HOYS project of NGC2244 in Hydrogen-Alpha. This was taken in strong moonlight but Ha images are much less affected. RGB was a non-starter with the Moon so strong.

Exoplanet X0-2 b

By |2020-01-28T19:33:49+00:007 January 2020|Categories: Exoplanet, News|

Second attempt at an exoplanet. Dips in light curve caused by a moving dark patch in light train – possibly dust or condensation. Would be better data if not for that. Also target is over-saturated again.

Qatar-1 b First Exoplanet

Been on my list to detect exoplanets for ages and finally got around to doing it. The data is messy and needs to be improved but it does fit the transit. Target star is over-saturated so never going to be good.

Top line shows curve before detrending – probably due to airmass changes. Quite serious clarity variations during session.
