* Comet PANSTARRS (C/2011 L4) in Cetus * Photo By Humayun Qureshi. Taken from Canberra. Astronomers discovered Comet PANSTARRS (C/2011 L4) on June 7, 2011. In early February, the comet reached its southernmost point, but by the end of May it will lie near Polaris (Alpha [α] Ursae Minoris). Comet watchers should target February 21 […]
This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. The aging star, cataloged as HD 140283, lies 190.1 light-years away. The Anglo-Australian Observatory (AAO) UK Schmidt telescope photographed the star in blue light. Credit: Digitized Sky Survey (DSS), STScI/AURA, Palomar/Caltech, and UKSTU/AAO A team of astronomers using NASA’s

A small group of us went to Cairns for the total eclipse. I wanted to see and photograph the event – the experience was quite something special but alas it was plagued with bad weather. I managed to photograph before totality and after, but during totality the cloud completely covered the wondrous sight. None the

It was a race to find the Higgs Boson – a scientific quest that has been years in the making. July 2 2012: The Tevatron: The scientists at the U.S. Department of Energy’s Tevatron collider revealed their latest results on July 2nd, two days before the highly anticipated announcement of the latest Higgs results from

The selection of the best site for the Square Kilometre Array (SKA), which was between South Africa and a joint Australian/New Zealand bid, surprised most people. But it makes real sense to utilize the preliminary facilities that both nations have started to contribute. In an earlier article on RelativeCosmos.com I suggested Australia would be best

By Estelle Asmodelle Recent reports on the selection of the site for the Square Kilometre Array (SKA) have suggested that South Africa offers the best site and a panel of advisors recommended the SA site over Australia. The argument was put that the SA site was cheaper for construction, yet Australia had lower insurance fees, and primarily
Square Kilometre Array (SKA) may go to South Africa but is it really the best site? Read More »
By Estelle Asmodelle The transit of Venus is happening 5th-6th June 2012. There are plenty of Astronomical Societies who are holding ‘transit parties,’ including two that I do presentations to: The first one, here is a page from the Newcastle Astronomical Society with their ‘transit party’ and they had ABC radio there as well: http://www.nas.org.au/HTML%20Pages/venus_transit_event_2004.htm

By Estelle Asmodelle Last December I joined the Newcastle Astronomical Society [NAS: http://www.nas.org.au/ ], that’s in Newcastle here in NSW, Australia – not the UK. When they had learned that I write the Space | Astronomy | Cosmology news for Cosmo magazine (sometimes) they invited me to give a series of talks – which I

New research examining the velocities of Type Ia supernovae suggests faster expansion in the northern hemisphere of the universe, challenging the cosmological principle that the universe is expanding uniformly in all
