Watch the Southern Cross for Earth Day!
Today is the 50th anniversary of Earth Day. Of course, I'm late to this. A number of astronomers have suggested that we use today (now tonight) to look up t they sky and esitimate the amount of light pollution that is affecting our world to mark Earth Day.
Globe at Night run Light pollution observing campaigns, all you have to do is go out when the sky is fully dark, look south and count the stars you can see in the Southern Cross, then fill out a report.
It's easy to do, fills in our knowledge of light pollution and connect us with the sky. Hopefully you are not clouded out like I am.

Globe at Night Light Pollution Campaign (May 25 - June 3, 2019)
The Globe at Night world light pollution survey runs each year now and are collecting observations during all 12 months of the year. The next survey period is May 25 - June 3 (starting Saturday).
Everyone can be involved, hopefully students and teachers too. Basically, after astronomical twilight (90 minutes after sunset ( best from 9-10 pm) head out, look to the north-west to find Bootes, (if you are in the northern hemisphere) or south to find Crux (for us southern hemisphere types) then check how many stars are visible for Bootes and Crux, and report your observations. It's a great excuse to get outdoors and look at the sky. You might even see the International Space Station.
This year you can submit your results a smart phone or tablet. To do this, you can use the web application at www.globeatnight.org/webapp/. Globe at Night is also on Facebook and Twitter.
There is a pod-cast on light pollution and a powerpoint presentation that explains about light pollution and how to do the sky survey, and special activities for kids. So go on, get out and have a go!

Dark Sky Events April 20-29
Dark skies are something we appreciate in the outback, when the full canopy of glittering stars are drawn over us. For those of us in suburbs and cities, the experience of dark skies is becoming rarer and rarer as light pollution encroaches.
International Dark Sky Week is an initiative of the International Dark Sky Association which aims to raise awareness of this issue, and runs from April 20-26 (April 21-27 in Australia). Why not check your local astronomical societies or the local planetariums and see if they are running dark sky events.
There is also the 5th International Earth and Sky Photo Contest on Dark Skies Importance, closing April 22 (April 23 Australia) it is a great opportunity to submit your dark sky images.
At the same time Globe at Night is running another of its global light pollution surveys from April 20 to April 29. This is good time to help find map the extent of light pollution around the world and how it is changing.
It might also be a good time to read this interview with renowned Australian astronomer Fred Watson on taking back the night sky.
As well, although not light pollution related, on April 22 (April 23 in Australia) NASA will be taking a Global Selfie for Earth Day. So get out and get snapping, and send your selfies in to the Global Selfie social media sites.
