Using innovation to light our world sustainably

Here at www.astredu.nz one of our main goals is to raise awareness about the importance of the night sky and how to protect and preserve natural darkness. We do this not just because we value the Cosmos, but because the night sky is integral to our wellbeing and that of the environment.

We are particularly interested in innovative, energy efficient and environmentally sensitive lighting because the world needs sustainable solutions to overcome light pollution. Best lighting practices are the way forward.

Thankfully, advances in technology offer systems that can meet a wide range of lighting requirements, including those that adapt to changing conditions. This is welcome news because towns and cities can select the best options for their particular needs, instead of following a one size fits all, blanket approach.

We are counting down to 14 July 2015 when the New Horizons spacecraft will fly by the binary dwarf planet Pluto-Charon. A lot of people, especially the New Horizons team at the Johns Hopkins Applied Physics Laboratory in Maryland, will keep their fingers and toes crossed, hoping that the painstaking preparations and the navigation of this unique mission will render the results as planned.

PlutoCharon300New Horizons will approach the Pluto system face-on almost perpendicular to the Pluto-Charon orbit which itself is almost perpendicular to the ecliptic. This view, as we also see it at the moment from Earth, happens during two periods of Pluto’s long orbit around the Sun. Early images from New Horizons have already shown the interesting “dance” of this binary system.
The animation here, which was made about at the time that New Horizons was launched, shows the mutual Pluto-Charon orbit to scale. The red dot indicates the joint centre of mass of the system, which lies more than 1000 km above Pluto’s surface (more than Pluto’s radius). Because of their relative size and distance, Pluto and Charon are in mutual tidal locking, which means that they face each other with the same side all the time.

New Horizons will fly close past this system on 14 July at 11:50 UT, at a distance 12,500 km from Pluto's surface. This is well within the orbits of the four moons Styx, Nix, Kerberos and Hydra, the furthest of which (Hydra) has an orbital radius of almost 65,000 km. During the flyby all systems aboard the spacecraft will work overtime, but the observations of the Pluto system have already begun long before that.

In 2013, I  had the great opportunity to interview the Chief Science Advisor of SOFIA, Eric Becklin whilst the flying telescope was here in New Zealand for its first southern deployment. During the interview, Eric Becklin told us about the telescope, the aircraft, about why SOFIA is in New Zealand and Southern Hemisphere, the wonders of infrared astronomy, favourite discoveries and what he thinks about the future of humankind.

Help needed: Questions from the Middle Pod (age 7/8)

User Rating: 0 / 5

I received this email from Lee - who organised the fantastic Space Night last week. The Middle Pod felt obviously VERY inspired by the amazing lineup of people who participated in the Space Night.

 20150620 180844

We need your help to answer these questions back to the kids!

 
'The middle pod (age 7/8) are doing space as an inquiry topic and have come up with some questions. Quite an impressive range of thinking.
 
I'm happy to research and answer, but if anyone wants to send me either some info or a full reply to any of these that would be very helpful.
 
I'm feel as though I might need to reach out to Steven Hawking on some of them...

Are we heading for a new Maunder Minimum?

Original image here.

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”.
