3:30 PM | Comet 67P/Churyumov-Gerasimenko Is Way Darker Than You Probably Realize
You'd never know from all the high-contrast photographs of Comet 67P/Churyumov-Gerasimenko that the comet is actually quite dark. This recently released composite image reveals how little light there is emanating from 67P/C-G, relative to other objects in our solar system.Read more...

3:19 PM | Tiny “nanoflares’ might heat the Sun’s corona
Why is the Sun’s million-degree corona, or outermost atmosphere, so much hotter than the Sun’s surface? This question has baffled astronomers for decades. Today, a […] The post Tiny “nanoflares’ might heat the Sun’s corona appeared first on Smithsonian Science.

12:25 AM | comet siding spring and mars
Comet C/2013 A1 (Siding Spring) will pass within 139,500 km (86,000 miles) of the surface of Mars at 5:51 tomorrow morning (Monday 20 Oct, Sydney time - or 19 October at 18:51 UTC).  This means Comet Siding Spring will pass 10 times closer to Mars than any (recorded) comet has flown by Earth!  But it will be traveling at 50 km/s which is too fast to be captured by Mars's gravitational pull.Comet Siding Spring was discovered by Rob NcNaught at Siding Spring Observatory in New South […]

5:20 PM | Does Saturn's 'Death Star' Moon Harbor A Hidden Ocean?
It's not the prettiest thing in the solar system, nor is it the most interesting. But Mimas — a pockmarked moon in orbit around Saturn — does exhibit a rather strange wobble. A team of astronomers say there can only be one of two explanations: either it's harbouring a subterranean ocean or it has an irregularly shaped core. Read more...

Now that ESA and its Rosetta mission have decided where to touch down on Comet 67P/Churyumov–Gerasimenko , they've invited the public to suggest what to call the landing site. The competition opens today and will run until 23:59 GMT on 22 October. Details here. Read more...

3:00 PM | Curious Signal Could Be Dark Matter Pouring From The Sun's Core
This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of 'axions' — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter.Read more...

2:00 PM | NASA’s MAVEN Mission Investigates Mars’ Atmosphere
NASA's latest mission to Mars, MAVEN (Mars Atmospheric and Volatile Evolution), entered Martian orbit less than a month ago on September 21. It's already rewarded us with revealing insights into the disappearance of Mars' atmosphere.

5:35 AM | Stargazing in October
What’s Up and Happening in our Skies Now that we’ve all enjoyed (if we could last week) the lunar eclipse, there’s a partial solar eclipse coming up next week that will be visible to at least some observers around the world on October 23rd. It’s partial because the Sun will only be partially blocked, which […]

11:00 PM | Moon Mining: NASA’s Plans to Harvest Water from the Moon
There’s a lot of water on the moon, and NASA wants to learn how to get to it. In July 2008, water was found conclusively for the first time inside ancient moon samples brought back by Apollo astronauts. In 2009, observations from three spacecraft showed signals of water across the moon’s surface, bolstering the idea that the moon might actually contain significant amount of water. Then, in October 2010, scientists reported that a frigid crater called Cabeus at the […]

4:57 PM | Milky Way ransacks nearby dwarf galaxies
Astronomers have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame. These new radio observations, which are the highest sensitivity of their kind ever undertaken, reveal that within a well-defined boundary around our Galaxy, dwarf galaxies are completely devoid of … Continue reading →

3:47 PM | Astronomers Discover Extrasolar Analog of Uranus 25,000 Light-Years Away
An ice giant that resembles our Solar System’s Uranus has been discovered about 25,000 light-years from Earth, by a multinational team of scientists led by Dr Radosław Poleski of Ohio State University and Warsaw University Observatory in Poland. The planet, labeled OGLE-2008-BLG-092LAb (092LAb for short), has a mass of about 4 times that of Uranus. [...]

12:52 PM | The Copernicus Complex by Caleb Scharf
I enjoyed Caleb Scharf’s previous book, Gravity’s Engines a good deal, so I was happy to get email from a publicist offering me his latest. I’m a little afraid that my extreme distraction of late hasn’t really treated it fairly, but then again, the fact that I finished it at all in my current state…

4:15 AM | Rosetta’s Tale
Origins In 1799 a French engineer stumbled upon what was to be one of the greatest archaeological finds in all of human history. On an expedition to Egypt with the purpose of undermining competitors’ trade interests to the East, an important stone covered in engravings was found and identified near the Nile Delta. British forces […] The post Rosetta’s Tale appeared first on HeadStuff.

i'm SO EXCITED to finally get to reveal this short film "steve and the stars" to everyone. i worked with the bluebottle group to produce it for the AAO. i think it captures the excitement and wonder, that cosmic vertigo that comes when thinking about our place in this unfathomably huge universe of ours. so lucky to be able to do this as my job! the official blurb and behind-the-scenes shots while filming in july 2014! Ever wonder what it's like to stay up all night using a world class 4-metre […]

12:36 AM | A Comet Passes by Mars; An Eclipse of the Sun
 On Thursday afternoon, Oct. 23, there will be a partial eclipse of the Sun, visible from the U.S. Different amounts of the Sun's area will be covered by the Sun. (For example, 40% of the Sun will be covered from the San Francisco region.) I have put question-and-answer introductions to the eclipse at: http://www.astrosociety.org/society-news/2014-eclipse-fact-sheets/ You can consult the national sheet for the degree the Sun will be eclipsed in your area. Here's wishing everyone […]

4:30 PM | Lifting the Veil on the Early Universe
The Creation of a Galactic Metropolis From time to time astronomers give us a peek at the early universe and each time they do, they lift the veil on earlier and earlier time periods of our cosmic history. In recent years, they’ve shown us early “shreds” of galaxies and hints of the first stars to […]

8:34 AM | Space weather today! Chances of a solar storm?
Mars Mission, Rosetta, International Space Station and the myriad number of man made satellites orbiting the planet, have already made it obvious that the human race has reached an age where it is looking further beyond its home, the Earth. And now, with companies like Virgin Galactic closer to offering sub orbital space trips to one and all (who can afford it), it has become paramount that we

How do we study the stars? Our best technology can send men to the Moon and probes to the edge of our solar system, but these distances are vanishingly small compared to the size of the universe. How then can we learn about the galaxies beyond our own? Yuan-Sen Ting takes us into deep space to show how astronomers study the stars beyond our reach.

3:09 PM | I’ll see you on the far side of the Moon
Modern humans have been around roughly 100,000 years, but until 55 years ago, none of us knew what the far side of our own Moon looked like. That changed in 1959 with the Soviet Union’s Luna 3 robotic probe, the first spaceship to travel around the Moon and return photos to Earth. My latest column […]
