In April 2002, whilst visiting NASA Ames' most priced building in the campus (energywise), I bumped into a poster of a huge aircraft. I love airplanes so my question was what was so special about this one that they had a poster of that size up on the wall. The answer came very quick. The aircraft (SOFIA) had a telescope inside it. Suffice to say that for me this is the epitome of heaven. Seriously, what can be more amazing (to an airplanes and stars lover) than an airplane with a telescope in it? With the mirror the size of the HSS (Hubble)! 

SOFIA stands for Stratosferic Observatory for Infrared Astronomy and it's a joint venture between NASA and DLR (German Space Agency).

Here are some quick facts on this wonderful flying machine

SOFIA Fact Sheet

SOFIA Self Guided Tour

With Sofia and David at AMES

SOFIA was built especially for flying across the Pacific so the aircraft has been here before on commercial flights. In it's current shape, it came to New Zealand in 2013 on her first deployment and is back now after two years with a hope for a life span of 20 years. You can find more about SOFIA here but also keep an eye on this site for more updates and stories on SOFIA. There will be more very soon!

We are coming out of the current sunspot cycle 24 which will end around 2019. The maximum of this cycle has yet again been well below that of the previous two cycles.

“Some studies show that sunspot magnetic field strengths […] are already close to the minimum needed to sustain sunspots on the solar surface”.
