Ceres Bizarre Bright Spot Now Has a Companion

Aliens making dinner with a solar cooker? Laser beams aimed at hapless earthlings? Whatever can that – now those – bright spots on Ceres be? The most recent images taken by the Dawn spacecraft now reveal that the bright pimple has a companion spot. Both are tucked inside a substantial crater and seem to glow […]

Peer Into the Distant Universe: How to See Quasars With Backyard Telescopes

How far can you see with that thing? It's a common question overhead at many public star parties in reference to telescopes. In the coming weeks as the Moon passes Full and moves out of the evening sky, we'd like to challenge you to hunt down a bright example of one of the most distant […]

Winds of Supermassive Black Holes Can Shape Galaxy-Wide Star Formation

The combined observations from two generations of X-Ray space telescopes have┬now revealed a more complete picture of the nature of high-speed winds expelled┬from super-massive black holes. Scientist analyzing the observations discovered that the winds linked to┬these black holes can travel in all directions and not just a narrow beam as previously thought. The black holes […]

Top 5 Under 40 in Australian Science

I'm very proud to announce that I'm a finalist for the Top 5 Under 40 in australian science! As part of the program, I'll attend a workshop this Thursday and Friday to get media production and science communication training, and then pitch an idea for a radio program to the panel of judges. eek! also, woohoo!This initiative is supported by UNSW and ABC Radio National to mark 40 years of The Science Show. The winners - the Top 5' - will be announced on The Science Show on 7 March

How to Photograph Tonight's Spectacular Triple-Play Conjunction

Tonight the thin, 2-day-old crescent Moon will join Venus and Mars in the western sky at dusk for one of the most striking conjunctions of the year. The otherworldly┬trio┬will fit neatly with a circle about 1. 5┬ wide or just three times the diameter of the full moon. No question, this will catch a lot of […]

How Can Space Travel Faster Than The Speed Of Light?

Cosmologists are intellectual time travelers. Looking back over billions of years, these scientists are able to trace the evolution of our Universe in┬astonishing detail. 13. 8 billion years ago, the Big Bang occurred. Fractions of a second later, the fledgling Universe expanded exponentially during an incredibly brief period of time called inflation. Over the ensuing eons, […]

Observing Galaxies with SAMI

I've been out at Siding Spring Observatory for the last week observing galaxies for the SAMI survey with the 4-metre Angle-Australian Telescope (AAT). Here's the story. arrive at siding spring observatory and hope to see crisp blue skies above the telescope dome. check the instrument hardwareplug the optical fibres into SAMI field plates. each of the silver ones will look at individual galaxies. the orange ones look at sky. hope that you get to go for a ride with SAM

A Star Passed Through the Solar System Just 70,000 Years Ago

Astronomers have reported the discovery of a star that passed within the outer reaches of our Solar System just 70,000 years ago, when early humans were beginning to take a foothold here on Earth. The stellar flyby was likely close enough to have influenced the orbits of comets in the outer Oort Cloud, but Neandertals […]

How do Gas and Stars Build a Galaxy?

When we look up at the night sky outside of the bright city, we can see a dazzling array of stars and galaxies. It is more difficult to see the clouds of gas within galaxies, however, but gas is required to form new stars and allow galaxies to grow. Although gas makes up less than […]

Black Moon: Why the New Moon on February 18th is Special

Take a speed of light trip across the solar system starting at the Sun We've heard it over and over. There's nothing faster than the speed of light. Einstein set the speed limit at 186,000 miles per second (299,792 km/sec). No material object can theoretically travel faster.┬For all practical purposes, only light is lithe enough […]

As the New Horizons spacecraft gathers information about Pluto before and after its July 2015 close encounter, practically every day we're learning more about this dwarf planet. Pluto is now becoming more to the public than just the planet that no longer was; before long, we'll be able to understand much about its atmosphere, its […]

Nobody Knows What These Mysterious Plumes are on Mars

In March 2012, amateur astronomers began observing unusual clouds or plumes along the western limb of the red planet Mars. The plumes, in the southern hemisphere rose to over 200 kilometers altitude persisting for several days and then reappeared weeks later. So a group of astronomers from Spain, the Netherlands, France, UK and USA have […]

The hunt for gravitational waves could be nearing success

Physicists are growing confident of detecting ephemeral ripples in the universe, and they are gearing up to engage the public in the discoveryHere's a date for your diary: 1 January 2017. It's the day that physicists are predicting for a great scientific breakthrough: the first direct detection of gravitational waves. Even if you have not yet heard about gravitational waves, you are going to in the coming years. When they are detected, it will revolutionise our investigation of the universe.

A Radio Look at Star Formation

Seeing Protostellar Baby Steps Until well into the 20th century, astronomers didn't have a clear look into the process of star formation. That's because the places where stars are born are veiled in heavy clouds of gas and dust. It had to be frustrating, seeing these blobs of star stuff in space and not being […]

Will Be Back

Since I moved to full-time freelance work last year (2014), I haven't been able blog that much. It's a myth that freelancers have more time in hand. When you have a full-time job with proper working hours, you stick to those and do bit more as well. But at the end of the day, you end up having time for other things. When freelancing, your work schedule gets filled around the clock, including weekends. But after an year, I have learned to organise time management much better. I'll be b

Lopsided' Supernova Could Be Responsible for Rogue Hypervelocity Stars

Hypervelocity stars have been observed traversing┬the Galaxy at extreme velocities (700 km/s), but the mechanisms that┬give rise to such phenomena are┬still┬debated. ┬Astronomer Thomas M. Tauris argues┬that lopsided supernova explosions can eject lower-mass Solar stars from the Galaxy at speeds up to 1280 km/s. ┬ “[This mechanism] can account for the majority (if not all) of […]

Two Stars On A Death Spiral Set To Detonate As A Supernova

Two┬white dwarfs circle around one┬other,┬locked in a fatal tango.

Or so goes the theory behind the infamous “standard candles” of cosmology. Now, in a paper published in today's issue of […]

Don't look at Black Holes Too Closely, They Might Disappear

We've come a long way in 13. 8 billion years; but despite our impressively extensive understanding of the┬Universe, there are still a few strings left untied.

It Turns Out Primordial Gravitational Waves Weren't Found

Last March, international researchers from the Background Imaging of Cosmic Extragalactic Polarization (BICEP2) telescope at the South Pole claimed that they detected primordial “B-mode” polarization of the cosmic microwave background (CMB) radiation. If confirmed, this would have been an incredibly important discovery for astrophysics, as it would constitute evidence of gravitational waves due to cosmic […]
