Queensland 'asteroid' sparks concerns over near earth asteroid monitoring
Astronomers have raised concerns about the ability to watch for near-Earth asteroids bigger than the one thought to have lit up the central Queensland sky on Monday night.Several experts said an asteroid was likely responsible for the multiple reports of a large bang, a flash in the sky and tremors near Gladstone about 8.30pm on Monday. Astronomer Owen Bennedick argued there needed to be funding for observatories to monitor asteroids.

Elon Musk will present the world with SpaceX’s plans for Mars colonization today in Guadalajara, Mexico — what should be the victorious presentation of a dream project. But he doesn’t have the money to get to Mars alone. So today he must either announce a substantial financial partner or woo one, in the face of a very recent SpaceX rocket explosion. There's one agency Musk needs to win over, and it already has its own Mars plans Ambitious space projects are glamorous, but this event isn’t real..>> view originalNew high resolution images reveal Mercury is tectonically active
NEW IMAGES FROM NASA's MESSENGER spacecraft have revealed previously undetected fault scarps – cliff-like landforms – on Mercury that are small enough to suggest the planet is geologically young. Published in Nature Geoscience, the new NASA findings suggests that Mercury is still contracting, and that Earth is not the only tectonically active planet in our Solar System, as previously thought. “The young age of the small scarps means that Mercury joins Earth as a tectonically active planet, with..>> view originalEarth's atmosphere is mysteriously losing oxygen
It sounds worse than it is: Earth's atmosphere is steadily losing oxygen. But before you panic and gasp for breath, understand that oxygen levels have only dropped by 0.7 percent over the past 800,000 years. So you don't have to worry about widespread asphyxiation just yet. Still, it's an alarming find that scientists aren't quite sure how to explain. In the study, researchers were able to measure atmospheric oxygen levels over time by analyzing tiny air bubbles trapped in ice core samples take..>> view originalMeteor described as 'mini sun' streaks over central Queensland
Meteor described as 'mini sun' streaks over central Queensland Updated September 27, 2016 15:27:54 A bright light and loud explosion in the sky over central and southern Queensland last night was probably a fiery meteor, experts believe.A number of Queenslanders have contacted ABC Local Radio to say they witnessed what appeared to be a fireball streak across the sky about 8.30pm on Monday night.Emerald resident Jim said he was on the phone at the time and was shocked by..>> view originalA rare 'black moon' is set to rise this Friday night
A rare 'black moon' will rise this Friday night, turning the sky dark as the Western Hemisphere experiences its second new moon of the month. Those on the other side of the world will have to wait until next month for the same event to occur, but it’ll be worth it - their eerie black moon is set to coincide with Halloween. If you’re having trouble keeping up with all the different types of 'moons' we've got now - with blood moons, blue moons, and supermoons clogging up your sky-watching calend..>> view originalClimate change study accused of erring on rising temperature predictions
