Hi everyone

Another busy month, some interesting ones on seti this month, along with neptune sized planets. There is also a detailed look at Europa too.

Official Attempt for Measuring light pollution

Hi Everyone, RASNZ and the Dark Sky Section of RASNZ in NZ have this awesome project where we can measure light pollution.
On Sunday, even if the sky is covered. Hope you can make it. Every one of us can make the difference. Thank you

Hari

On Sunday 21 June 2020, On the darkest day of the year.... join us to measure light pollution even if it's raining.
Have you heard about light pollution?
Don't like that light shining in your bedroom window? Want to do something about it?
Join us to preserve the night by being part of a Guinness World Records ™ Official Attempt for Measuring light pollution!
