Posted February 4, 2016 By Kevin Orrman-Rossiter

Kevin Orrman-Rossiter, University of Melbourne and Alice Gorman, Flinders University Recognise these planet names: Vulcan, Neptune, Pluto, Nemesis, Tyche and Planet X? They all have one thing in common: their existence was predicted to account for unexplained phenomena in our solar system. While the predictions of Neptune and Pluto proved correct, Nemesis and Tyche probably […]

Finding Pluto: the hunt for Planet X Kevin Orrman-Rossiter, University of Melbourne and Alice Gorman, Flinders University Our solar system’s shadowy ninth (dwarf) planet was the subject of furious speculation and a frantic search for almost a century before it was finally discovered by Clyde Tombaugh in 1930. And remarkably, Pluto’s reality was deduced using […]

Introduction Here I will be arguing that comets were not instrumental in the emergence of modern astronomy in the 17th century. This view, most notably propounded by Kuhn and Hellman , where observations of comets were of paramount importance in ushering in a post-Newtonian modern astronomy by the end of the 17th century. Heidarzadeh posits […]

Apollo 11: it was 45 years ago today

Posted July 20, 2014 By Kevin Orrman-Rossiter

What a time to ‘have to’ go and buy milk. Mid-morning Monday, July 21 1969, and my mother sends me up the street to get some milk. No big deal, you might say. However, a few hours prior to then, at 6:17 AEST that morning to be precise, a fragile craft, called the Eagle, had […]

The Right Stuff: astronaut biographies from Glenn to Hadfield

Posted April 15, 2014 By Kevin Orrman-Rossiter

An enduring image of an ‘astronaut’ was created for the public by NASA, Time magazine, and Tom Woolf’s The Right Stuff. These caricatures of  the original seven American astronauts, the so-called Mercury-7, chosen to assert American supremacy over the communist threat of Sputnik have seemingly endured way past their use by date. A resurgence in […]

Pluto’s new moons named: Spock still homeless

Posted July 8, 2013 By Kevin Orrman-Rossiter

The dwarf planet, Pluto, can still generate public interest – if the naming of its two recently discovered moons is anything to go by. After their discovery, the leader of the research team, Mark Showalter, called for a public vote to suggest names for the two objects. The contest, aptly named ‘Pluto Rocks!‘, concluded with […]

Explainer: the International Space Station

Posted April 25, 2013 By Kevin Orrman-Rossiter

As the most visible man-made object in the night sky the International Space Station (ISS) is of significance to humankind. It takes humans from being explorers of space to being residents of space. The Russians launched Zarya, the first module of the ISS, on November 20, 1998. It has grown considerably since then and has […]

Kepler meets Einstein: a gravity-bending feat

Posted April 13, 2013 By Kevin Orrman-Rossiter

NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon — a prediction of Einstein’s general theory of relativity — in binary, or double, star systems. The dead star, called a white dwarf, is the burnt-out […]

Long distance weather reports are now a commonality. The report for 2MASSJ22282889-431026 is somewhat unusual. It forecasts wind-driven, planet-sized clouds, with the light varying in time, brightening and dimming about every 90 minutes. The clouds on 2MASSJ22282889-431026 are composed of hot grains of sand, liquid drops of iron, and other exotic compounds. Definitely not the first […]

Interstellar travel: how to spot a ‘starman’ going by

Posted February 23, 2013 By Kevin Orrman-Rossiter

Massive objects moving at near light speeds do not occur naturally in the universe as we know it. If we detect such objects it is a reasonable to assume they are artificial artifacts from advanced intelligent life. This according to Garcia-Escartin and Chamorro-Posada, authors of a recent paper, is a low-cost, sure-fire way of searching […]

Its a wheel! its a wheel – a wheel on Mars!

Posted August 25, 2012 By Kevin Orrman-Rossiter

NASA’s rover Curiosity was safely on Mars.  It was a perfect landing.  The novel sky-crane method had proved its detractors wrong and its designers right.  What was needed then was signs that Curiosity was working as designed.  NASA had said that the first pictures may be anything up to 2 hours after landing.  A long […]

The Earth just aged a little bit more

Posted April 12, 2012 By Kevin Orrman-Rossiter
This composite image of the Tycho supernova remnant combines X-ray and infrared observations obtained with NASA's Chandra X-ray Observatory and Spitzer Space Telescope, respectively, and the Calar Alto observatory, Spain. It shows the scene more than four centuries after the brilliant star explosion witnessed by Tycho Brahe and other astronomers of that era.

Who found the water on the Moon?

Posted March 28, 2012 By Kevin Orrman-Rossiter

At just over two tonnes, the second stage of an Atlas V rocket makes for an unusual ‘kinetic probe’.  Nonetheless on October 9, 2009 NASA deliberately impacted a spent Centaur rocket into the lunar south polar crater Cabeus.  The target area was a permanently shadowed region within this crater.  The impact, not surprisingly, ejected a […]

Hubble finds a dark matter puzzle

Posted March 9, 2012 By Kevin Orrman-Rossiter

Astronomers using data from NASA’s Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision. Abell […]
