After evolving a digital heart (not the pacemaker kind) out of inky veins, Jamie just wants an excuse to learn something new. But he’s fully aware his 32 years’ experience in the news industry has given him just enough knowledge to be dangerous. International affairs. History. Defence. Science. Space. Technology. He has a fascination for them all – particularly when it comes to social fallout. Translating tough concepts into common terms is his craft. His passion is to explore the big picture encompassing world events.

A big, bad nuclear boom on Mars?

A big, bad nuclear boom on Mars?

IT’S a favourite among Red Planet conspiracy theorists: That a massive nuclear war scorched Mars lifeless. Now a new photo is being bandied about as “evidence”.

This image shows the huge galaxy cluster MACS J1149+2223, whose light took over 5 billion years to reach us. The huge mass of the cluster and one of the galaxies within it is bending the light from a supernova behind them and creating four separate images of it. The light has been magnified and distorted due to gravitational lensing and as a result the images are arranged around the elliptical galaxy in a formation known as an Einstein cross. A close-up of the Einstein cross is shown in the inset.

Captured: A twist in space and time

BOOM. Bend. Repeat. The universe doesn’t only have a sense of humour, it’s also a tease. Twists in space and time have given us a four-split view of a supernova. And we’ll get a re-run.

Deep Caption: Exercise Pacific Reach is a triennial Asia-Pacific submarine rescue exercise designed to promote regional cooperation on submarine rescue. The exercise this year is the fourth in the series and is being hosted by Australia between 26 November and 7 December 2007. Pacific Reach 07 is a significant exercise involving six ships, three submarines, two submarine rescue systems, a multi-national dive team and the UK SPAG† all up 1000 personnel from 15 nations will be directly involved in the exercise. Pacific Reach is an extraordinarily valuable opportunity to work with our regional neighbours and it is our pleasure to host this years activities, said Commander Australian Naval Submarine Group, Commodore Rick Shalders. Pacific Reach is a truly international exercise, with units and equipment from the following countries participating: Canada, China, Republic of Korea, Japan, Malaysia, Singapore, the United States and the United Kingdom. In addition, military observers from Chile, India, Indonesia, NATO, Pakistan, Peru, Russia and South Africa will also attend.

Navy boss sunk by Wikipedia

IT took little more than Wikipedia for Senator Nick Xenophon to outsmart Australia’s top Navy brass on the topic of our costly new fleet of submarines.

This Hubble image shows RS Puppis, a type of variable star known as a Cepheid variable. As variable stars go, Cepheids have comparatively long periods — RS Puppis, for example, varies in brightness by almost a factor of five every 40 or so days. RS Puppis is unusual; this variable star is shrouded by thick, dark clouds of dust enabling a phenomenon known as a light echo to be shown with stunning clarity. These Hubble observations show the ethereal object embedded in its dusty environment, set against a dark sky filled with background galaxies.

Astronomy’s darkest discovery yet

DON’T look now. There’s an entire invisible galaxy lurking right next door. We can’t see it. But the telltale signs of its presence are starting to show…
