Carnival of Space 365

WELCOME to Carnival of Space 365. A weekly round-up of Space and Astronomy Blogs that is in its 365 Week. Thats a whole year of weeks! What a week its been, with the Rosetta Probe getting ready for its "Philae Mignon" with Comet 67P. (See what I did there ... huh ...huh) Watching too many cooking shows? Should be doing more science!

OK ... I know its not going to wrap it in bacon.... lets move on.

Astronomy is going off this week, lots of stuff happening!

Dr. Paul Spudis comments on Buzz Aldrin's case for the immediate adoption of a new national goal in space – a human mission to Mars.

The Lunar PLanetary Institute covers a new study in Nature that describes the effects of asteroid bombardment on the early Earth

We take a close look at the surface of Mercury with PlanetMappers as the MESSENGER Spacecraft makes its closest approach to the planet so far.

Also from the team at Cosmoquest - What's the forecast for this year's Perseid Meteor shower, and how can you contribute to citizen science and observations of meteors and fireballs?

Perhaps at this point I can put in a little plug for the brilliant the new App "Fireballs in the Sky" developed by the team at Curtin University. You can measure and report meteors and bolides with your phone as they happen.

Spacewriter talks about "Telescopes to Tanzania", a project of Astronomers Without Borders. There is alot of great work going on in Africa with astronomy right now!

Carolyn Collins Petersen, space/astronomy expert at About.com, takes a look at a few of the many excellent space and astronomy education resources available to educators and outreach professionals.

NASA announced the winners of the high stakes science instrument competition to fly aboard the Mars 2020 rover at a briefing held today, Thursday, July 31, at the agency’s headquarters in Washington, D.C.

Scientists analyzing the reams of data from NASA’s Cassini orbiter at Saturn have discovered 101 geysers erupting from the intriguing icy moon Enceladus and that the spewing material of liquid water likely originates from an underground sea located beneath the tiny moons ice shell, according to newly published research.

Success and validation that aligns with what is believed about EmDrive means powerful mainly static thrust. It would be an alternative way to achieve effects that would mimic antigravity. It would enable super efficient planes, better flying cars, and cloud city like applications in a full expression of a mature EmDrive. In the nearer term it would be better satellite propulsion. A US scientist, Guido Fetta, has built his own propellant-less microwave thruster, and managed to persuade Nasa to test it out. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio. Astonishingly enough, they are positive. Read all about it here including similar experiments in China ......

Next Big Future also reports on producing black light power using Hydrinos.

See what happens when two passions collide. A crafty spacer explores an idea and lives to tell the tale!

I think she nailed it!! - Editor

A look at the density perturbations in the early universe from which galaxies and others structures formed, with a visual explanation of the effect of gravity on these perturbations.

Thanks for joining us this week at the AARTScope Blog where we keep creating the sense of anticipation and discovery that keeps people asking questions. I'll leave you with my image of the Saturn Occultation last night!

So that about wraps it up for this weeks Carnival of Space. For image Credits see the original blogs. The Carnival of Space is a community of interest blog carnival bringing together the best and brightest Astronomy & Space Blogs at a single point in space and time (commonly referred to as a web address) each week.

Saturn Occultation from Southern Australia Aug 4th 2014

A very quick post with an image of tonight's occultation from southern Australia.

Enjoy!

Saturn Occultation by the moon - May 14 2014

Thanks for joining us tonight for the live hangout on air. Enjoy!

Not really ideal. The full moon was shining through thin cloud washing out a bit of the detail. The telescope is still ste up hopefully the cloud will clear and I can get some better stills on the egress.

Live hangouts and driving a telescope live is a tricky business. I lost focus playing around trying to improve the image due to the thin cloud. Managed to get it back into focus just as it was disappearing. The relative motion is pretty quick once you see them that close together.

One hour and ten minutes later it re-emerges with the moon a little clearer now, but surrounded by a bright halo. This time I am directly imaging it with the DLSR as well, so a really nice couple of shots on egress.

And so..... The moon drifts on towards full lunation later tonight, as Saturn slips behind it.

Carnival of Space 281/282

My final honored task for 2012 is to host the Carnival of Space. What a year it has been! From the Transit of Venus, the successful Curiosity landing, the SKA being jointly awarded to Australia and Europe, the Higgs Boson the emergence of +Virtual Star Parties in Google Plus Hangouts, its really hard to know where to start.

Its been an amazing year. Astronomy has in someway led the charge in the Social Media/Science Catagory through strong leadership, mentoring and driving new horizons literally!!!!

To all readers and contributors I hope and trust that 2013 will bring you, and those close to you, a happy, prosperous new year that expands your understanding of the Universe around you, and all the players in its magnificent symphony.

On with the show!!!!!

Cheap Astronomy launches the e-book Astronomy Without a Telescope - which is surprisingly cheap (podcast). eBooks are great and with recent upgrades to smart devices and tablet software you can usually download them really easily into your reading device of preference.

How was born the Moon? Doc Madhattan replies to this quest starting from the Earth-Moon Theory and the works of George Darwin. I also translate some quotations from the short stories by the italian writer Italo Calvino.

The Chandra Blog gives us our first new year's resolution :- Never Give Up And Trust Your Intuition. In fact they push the boundries even further with From Super To Ultra: Just How Big Can Black Holes Get?

The Meridian Journal reports on the Cassini probes discovery of an alien version of the ‘Nile River’ on Titan.

Next Big Future brings us a report on how Orbitec has flown a radical new engine technology that promises to cut the size, weight and therefore the cost of putting a rocket – and payload – into space. Regular rocket engines get incredibly hot, reaching temperatures upwards of 3,000C (5,400F) or more, hot enough to melt the metal chamber in which the rocket fuel mixes with oxygen and burns. At these extremes, even rockets with sidewalls made of heat-resistant superalloys would fail catastrophically. Orbitec’s alternative approach keeps the hot burning gases away from the chamber surfaces altogether. The company’s patented designs create a cyclonic swirl, or vortex, of fuel and oxygen that holds the searing gases and fumes in the very centre of the cylindrical combustion chamber, away from the vulnerable sidewalls.

The meticulous chronicler of all things relating to Space Missions - Amy Shira Teitel discusses the story of how being on the Moon inspired Apollo 17's Jack Schmitt to write some holiday poetry. I'm sure its better than Vogon poetry!

From the Links through Space Blog you can follow Astronomy Club Toutatis on it's trip to Morocco. A series of posts and photos on Moroccan astronomy and personnel experiences through out Marrakesh and the Sahara desert night sky. Read about the observatory of Marrakesh, Asteroid Toutatis, see the Geminid meteor shower from the desert, Step in the Sahara sky hotel in the middle of nowhere in the Sahara desert for deep sky object photographing.

We occasionally see the magnificent photographer Thierry Legault sneak into Australia for magnificent outback shots. Today he sent Universe Today some images from an aurora-hunting trip to Finland and Norway. As you can guess, the images are awesome!

Finally my own AARTScope contribution of the top five highlights of my Astronomical year, a list which runs to many more than five, but the top five are biggies!

It s been my priviledge to continue the mission of the AARTScope Blog to Create the sense of anticipation and discovery that keeps scientists asking questions once again in 2012, and also host the Carnival of Space a number of times. Thanks for joing us again.

Roadtesting the Orion Steadypix adapter for the iPhone

Well it finally arrived, not because they were slow in delivering, but because I finally got around to ordering the quintessential adapter/tool/dongle.....(its not really an app) for the iPhone - The Orion Steadypix camera adapter.



Well folks, you know when you lie awake at night thinking "what could I invent, get made up in China for a couple of dollars and sell 50,000 of before anyone else thought of it". Well the Steadypix is just one of those things.

Regular readers of my blog will remember my ham-fisted attempt to create one myself.


Remember all those cartoons about "as the architect designed it, as the engineer built it.....and how the customer got it.


Well this is what it looks like, when someone who knows what they are doing, designs and builds it (queue free plug for Orion Optics).

Silly me (after trying to collimate my telescope with a laser collimator and the barlow still in....d'oh) I had realized I'd also forgotten to charge up the battery so the dobby was unable to be guided. So not a bad result at all considering there was a little drift of the image to account for.


The moon is so bright through a telescope you need a lunar filter to kill off some of the light. Most entry level telescopes come with this filter included. Also, you soon learn that the full moon is not the best time to look at the moon through a telescope. Targeting limb of the shadow zone gives the best results as the suns rays are hitting the surface at a low angle and illuminate all kinds of detail, from the edges and centers of craters to impact trains, valleys and ridges. Its almost like being in the command module of Apollo 11.

Diligent observers have also witnessed transient events where gases escape from fissures in the surface and are illuminated as they rise through the shadow zone.

More recently some observation programs look for meteors in the "dark of the Moon" when meteor showers are in progress. The science of the moon is very much alive!

All in all a pretty good result - Enjoy.
