Science in the ’20s – part 1 - Ariadne

Robert Hickson Jan 15, 2020

  Outrageous, immoral or downright dangerous. That’s a description of the lifestyle of women “flappers” in the 1920s. Could it apply to science (and scientists) in the 2020s? Actually, you could look back at the past decade and see those, or similar terms, used about some science and scientists. Sometimes justifiably, most times not. Looking ahead ten … Read More

Southern Cross and Pointers Painted Large Across Christchurch - Out of Space

Duncan Steel Dec 25, 2019

Using knowledge of when the Sentinel-1A radar satellite was due to pass over New Zealand, a team at Christ’s College laid out specially-constructed radar retroreflectors across Hagley Park in Christchurch, in that way painting the Southern Cross and the Pointers in a huge array clearly visible in the derived radar image of the city.  A special – but brief – … Read More

Kiwi exoworlds are named - Out of Space

Duncan Steel Dec 20, 2019

The International Astronomical Union (IAU) this year invited nations to propose names for distant stars selected on the basis of having planets (exoplanets) discovered to be orbiting them. The New Zealand entries, now adopted officially by the IAU, are Karaka for the star, and Kererū for its associated exoplanet.  In a previous blog post I described how New Zealanders had … Read More

Skeletons in the closet: my ancestry DNA story - Lost Worlds, Vanished Lives

Nic Rawlence Dec 17, 2019

‘Are you sitting down?’ the ominous words came down the phone line. Usually, that means something less than happy is about to be imparted. ‘It’s about your grandparents ….’ I grew up in the sunshine capital of Aotearoa New Zealand. My maternal grandparents lived just down the road. My grandfather was always a big part of my life. When not … Read More

Anti-neutrinos–When you are your own opposite - Physics Stop

Marcus Wilson Nov 28, 2019

Around a million billion pass through you each second, almost all originating from our sun, but few of them are likely to interact with you enroute. I was reading in a physics magazine earlier in the week about the nature of neutrinos. These are extremely numerous elementary particles, but only interact very weakly with anything.  A typical neutrino will travel … Read More

Among my favourite asteroids: (2309) Mr. Spock - Out of Space

Duncan Steel Nov 27, 2019

Minor planet/asteroid (2309) Mr. Spock is named not for the character in Star Trek, but for a cat that was itself imperturbable, logical, intelligent and had pointed ears.  In a preceding blog post I introduced one of my favourite asteroids, (2472) Bradman, and also mentioned (6581) Sobers amongst a few others. I did have something to do with the … Read More

Among my favourite asteroids: (2472) Bradman - Out of Space

Duncan Steel Nov 25, 2019

There are many thousands of asteroids with formal names, some humdrum but other more noteworthy (depending on your predilections). One of my favourites, the name of which I was involved in suggesting, is (2472) Bradman, named for the Australian cricketing great. After discussing (2472) Bradman, I also make some comments about (6581) Sobers.  As a minor planet (synonym: asteroid) spotter, … Read More
