A spooky interview as an object (fittingly a 'dead' comet) will flyby Earth on Halloween just further than the Moon's is from us. I spoke about the furthest galaxies from us that Hubble has found (using a high-tech martini glass) and a dead star that is tearing apart the planets in its solar system that will likely happen to use in five billion years time.

One of the best science lectures I've ever seen was at Monash University by Caltech's legend GR expert Prof Kip Thorne giving the Einstein Centenary lecture to celebrate a century since General Relativity was released to the world. Fittingly, he used the examples of Interstellar's Black Holes, time dilation and 5-dimensional (bulk) beings to make the topic all the more accessible to the (sold out) auditorium.

My thoughts on a mysterious star that has its light blocked as something huge passes between us and this star. It could be a swarm of comets blocking the light as a nearby star flew by and disrupted comets in the Oort Cloud and sent them spiralling inwards. Another option is that it could be a Dyson Sphere, essentially the natural extension of solar panels in space that surround the star and block its light.

I spoke about the amazing Apollo Archival Project has put thousands of Apollo era photos on flickr and the discovery that Pluto has blue skies, something we take for granted on Earth but it's actually really unusual in our solar system!

Einstein predicted ripples in the very fabric of spacetime itself from violent collisions by massive objects like Black Holes. The latest search to find those ripples, or gravitational waves, have come up with only limits. Was Einstein wrong about these waves or is it our understanding of merging black holes? My thoughts in Cosmos Magazine.

Chatting to ABC's The Drum about the water on Mars with the implications that has for our chance to explore it, and the importance of doing so for our future on Earth.

On Earth, where there's water there's life so "follow the water" has been NASA's scientific guide in exploring Mars. That effort paid off today with the confirmation that liquid water is flowing on the surface right now. This has implications for both the possibility of life and habitability by human explorers.

This Monday will see the last lunar eclipse of the tetrad (sequence of four). A beautiful sight as the moon turns 'blood' red that millions across Europe and America will enjoy. For some however they see it as the apocalypse. Unsurprisingly I am less pessimistic in my explanation on theconversation.

A website tracks PhD supervisors to find your 'academic genealogy' and none-other than Stephen Hawking is my Great-Grandad! Meaningless but hilarious.

Dark matter is invisible and able to pass through matter almost completely without notice. As you might imagine finding it is a challenge. By using telescopes, particle colliders and 'glowing' crystals at the bottom of goldmines we are honing in on this mysterious new particle.

I was delighted when three RMIT students asked me to help explain the Aurora (the Northern / Southern lights) with them in this fantastic animation. There's something really engaging about this old school style that more recent digital graphics can miss. But decide for yourself..!

I chatted about a recently discovered tornado on the Sun, the most distant galaxy and alien abductions in Northern Territories. Being asked about Probes by Virginia Trioli is a career first.

NASA has undertaken a year long isolation experiment with 6 volunteers living in a dome no more than 11m wide and 6m to practice psychological survival techniques for the voyage to Mars. Unbelievably one of the volunteers brought a ukulele along to learn. They're first out of the airlock I'm guessing.

Every fortnight I get to sit on the couch and chat about the latest awesome science and events in space. Today was all about Rosetta watching Comet67P flare into life as well as space lettuce. Tastes like rocket apparently. Apologies for the puns.

My student's third paper of a stunning 3-part series on the growth of dark matter structures. In this paper Camila finally demonstrated the long studied concentration of dark matter haloes was tied to the growth history of that halo and hence, through her other works, the basic cosmology of the universe.

Are we alone? It's a fundamental question that haunts us as we look up into a cold, dark sky and (so far as we know!) the answer is yes, but perhaps for not too much longer. With $100m from the Breakthrough Listen project Australia will be leading the search for ET's signals. This is something that everyone is fascinated by, including politicians! Myself and a group of distinguished scientists gave a briefing at Parliament House to, amongst others, then Minister for Industry Ian Macfarlane and Minister for Science Karen Andrews (seen above with me politely trying not to be bored by my awful ramblings).
You can watch the interview at the National Library of Australia hosted by 666 ABC Canberra's Genevieve Jacobs, Nobel Laureate Prof Brian Schmidt, Prof Naomi McClure-Griffiths, Laureate Fellow Prof Matthew Bailes, Prof Paul Davies and yours truly (completely out of my depth!)
You can also listen to the earlier news briefing arranged by AusSMC (Australian Science Media Centre)

An amazing chance to open for Neil deGrasse Tyson in front of 5000 people, speaking about dark matter and generally hanging out with him backstage (and yes he's a top dude).

More awesome results from Rosetta and in particular it's epic Philae lander has found organic material on the surface of Comet 67P

The discovery of the closest Earth-like world yet has huge implications for the search for alien life. We think this world will likely be too hot but it means rocky worlds similar in size to us really are everywhere... So where are all the aliens?

I made it to the panel of ABC's The Drum to chat about finding aliens with the amazing Breakthrough Listen project and the lead role Australia is playing in this endeavour.
