Interstellar comet update - Out of Space

Duncan Steel Sep 19, 2019

The discovery of a true interstellar comet – a comet passing through the solar system having arrived, presumably, after having been thrown out of some other planetary system orbiting another star – re-opens a long-debated question in science: is life unique to Earth, or is it common in the galaxy? The panspermia hypothesis holds that life is common in the … Read More

Considering the Character of Galaxies - A History of NZ Science in 25 Objects

Jean Balchin Jul 04, 2017

One day, when I was seven years old, I decided to camp out in the treehouse with my brother John. It was a poorly planned venture from the start; we misjudged the cold, the ferocity of the mosquitoes and our own temperaments. John got spooked looking at the gnarled bark of the tree, reading faces … Read More

Is our Milky Way galaxy a zombie, already dead and we don’t know it? - Guest Work

Guest Author Jan 29, 2016

Kevin Schawinski, Swiss Federal Institute of Technology Zurich Like a zombie, the Milky Way galaxy may already be dead but it still keeps going. Our galactic neighbor Andromeda almost certainly expired a few billion years ago, but only recently started showing outward signs of its demise. Galaxies seem to be able to “perish” – that is, stop turning … Read More

“Just So Science” – The Cosmos Wanderers - Just So Science

Elf Eldridge May 19, 2011

So the big astronomy news of today is the announcement of “Unbound planetary mass objects” around stars towards the centre of our galaxy. Now before i get too excited, I should probably mention that we have discovered large free-floating planets before (maybe) but these have been confined to large clouds of dust and gas near star forming regions – this … Read More

“Just So Science” – A Song of the Universe - Just So Science

Elf Eldridge May 17, 2011

After finally finding time to catch up on new Dr Who over the weekend, I was inspired to write a little about the music of the cosmos. We don’t usually think of the stars as being intrinsically noisy, but since the advent of Radioastronomy it has become possible to ‘listen’ to some of the signals … Read More

“Just So Science” – The Clouds that Weren’t - Just So Science

Elf Eldridge May 11, 2011

What’s the best thing about living in the Southern Hemisphere? Winter! Sure, the above image is taken from an observatory in Chile, but in NZ we get treated to a similar view of the centre of our galaxy, the Milky Way, and they just get better and better as we move further and further into winter. To … Read More
