It is very rare that I come across someone with star quality. Having said that, I have stumbled across a few stars in LA, such as Harrison Ford (great), Clint Eastwood (awesome) and Brittany Murphy (nice) because I’m only 20 minutes away from the city. These things happen in a place where its main (only?) industry is celebrity and film. Oh yes, I’ve also had dinner with Billy Dee Williams, stood in a queue with Jerry O’Connell (he was buying dog food) and tripped over Nicole Richie (she is rather tiny after all). However, when it comes to meeting somebody before they became famous… I draw blanks. Hardly surprising really, I’m no talent scout and I spend most of my time typing, indoors. I need to get out more.
In the short time I spent with George between the AAS presentations and (free) beer, I realised this guy has star quality. This was confirmed when he performed live at the grand opening of the International Year of Astronomy 2009. And what did he perform? His signature theme tune, “Far” for the 365 Days of Astronomy podcast, only this time with audience participation. Needless to say, George did a superb job, he has great talent and he’s a genuinely nice guy. Plus, he’s a skeptical thinker and embraces space, science and logical thinking. My prediction is that George Hrab really will go FAR (uber-far)…
From Carolyn’s well-crafted peek into the space blogosphere, here’s a tiny fraction of articles that caused a derailment to my plans for getting any work done this afternoon (plus my first reaction, in a word):
It’s another one of those “I wish I’d thought of that” moments. Well, at least it would have been if I knew Morse code. And if I was an astrophotographer. I have a camera, and some patience, and have worked out how to capture the Moon with my ancient SLR, so perhaps there’s some hope yet? Nah, I’ll give up on this one.
Jimmy Westlake from Colorado took this shot of star trails, with the brightest star being Sirius. Usually, star trails are continuous arcs of light after keeping the shutter of the camera open for minutes-hours at a time. You’ll notice that this picture is different, the star trails are broken. It turns out that Westlake wanted to celebrate the International Year of Astronomy 2009 in his own way:
“This is actually a series of 28 separate exposures on one piece of film. The ‘dots’ are 30-second exposures; the ‘dashes’ are 3-minute exposures. The ‘shutter’ creating the gaps was my shivering, gloved hand held over the lens in the 0ºF Colorado air. The entire message required just under two hours to record. Every few minutes, I had to turn on a blow dryer to keep the frost from forming on the lens–and me!“
I’ll let you try to decipher the code if you can read Morse code, otherwise read on for the answer… Continue reading →
The day has come. Finally, I get to promote my excitement for the importance of Space Beer. Ohhh yes! Incidentally, Space Beer has been the theme of the last few days of the AAS conference (free beer, special free Galileo limited edition Sierra Nevada beer. Did I mention it was free?), so it seems fitting to have my 365 Days of Astronomy podcast broadcast the day after returning from the conference fuelled by (free) space-themed booze.
To top the whole experience off, I had the superb fortune to meet the musician behind the 365 Days of Astronomy theme tune, plus we were also treated to a mini-concert by him during the official USA opening of the International Year of Astronomy 2009 at the AAS conference on Tuesday. Written and performed by George Hrab, the entire audience at the IYA2009 grand opening ceremony had a great time singing along to the lyrics. I’m assuming the song is called “Far”, for obvious reasons. Funnily enough, in the audience participation parts of the tune, avatars participating in the Second Life virtual world were also singing along. George not only entertained the real world, he transcended this life to make the Second Life rock! Now that is inspirational!
Back in 2006, I was feeling a bit nostalgic about my four years of research at the University of Wales, Aberystwyth Solar Group, so I decided to try to find some high resolution prints of the Sun. After a lot of effort, I didn’t find any prints I could buy or download, but I did find some high resolution images from the Solar and Heliospheric Observatory (SOHO) image archive. Although some were a bit noisy, I was able to clean them up with Photoshop and did some layer tweaking/saturation/balance to draw out the fine detail of the chromospheric network–as seen above in the 304A Extreme ultraviolet Imaging Telescope filter–plus a distinct prominence (in the bottom left-hand of the image).
Not stopping there, I decided to give the same treatment to high resolution 171A and 195A images. They came out very well and I kept rotating them as my wallpaper for months. Having just read Phil’s post on today’s perihelion (the time of year when the Earth is at its closest to the Sun during its orbit), I came across a comment asking whether anyone had any wallpapers of the same 304A EIT image. Well, here it is! Plus two more!
If anyone wants to find out how the images were edited, feel free to ask and I’ll let you know. Truth be known, there’s thousands of space images held by NASA, ESA etc. open to the public domain that rarely get the “airtime” they deserve. So it’s about time I dust off these three-year old edits and share the magnetohydrodynamic love.
I miss active regions, I wish the Sun would amp it up a bit so we can see all those lovely flares, CMEs, filaments and coronal loops… ahhhh… coronal loops…
Four centuries after Galileo Galilei first pointed his telescope at the night sky, the international community will not only be commemorate Galileo’s momentous discoveries, we will celebrate mankind’s continuing scientific endeavours in space. Back in 2007, the United Nations decided 2009 should be dedicated to astronomy and named it the “International Year of Astronomy”. It is going to be a huge year for all astronomical disciplines, intended to educate, celebrate and enjoy the wonders of the cosmos. Many events are planned throughout the coming twelve months, in the 135 nations participating. You won’t be far away from an IYA2009 participating group or organization, so be sure to embrace this landmark year, it could change the way you view the Universe forever…
A white dwarf called KPD 0005+5106 has been identified as the hottest star observed, ever. KPD 0005+5106 lives in the globular cluster M4, 7,200 light years away, and astronomers have always been intrigued by this stellar lightweight as its emissions have previously hinted it was quite toasty. Now, astronomers using data from the defunct NASA Far-Ultraviolet Spectroscopic Explorer (FUSE), have studied the white dwarf in more detail. KPD 0005+5106 emits radiation in the far-ultraviolet, indicating that its surface has a temperature of 200,000K. This is an unprecedented discovery, far-ultraviolet emissions are usually reserved for superheated stellar coronae. It may be small, but it’s a record-breaker… Continue reading →
I must admit though (as one of my readers pointed out), it is surprising to hear about this recent flurry of large fireball events. Some of these meteoroids are as big as 10 tonnes (in the case of the Saskatchewan fireball), and scattered meteorites are being found on the ground (fortunately over sparsely populated regions). Are these recent series of fireball spottings down to improved observation techniques and a bit of luck? After all, the October fireball was observed directly over several all-sky cameras dedicated to spotting meteors; the November fireball was seen by a huge number of people in cities across the Saskatchewan/Alberta border and last night’s fireball appeared above another dedicated meteor all-sky camera.
A few of these events are expected every year, so this is certainly nothing to be concerned about, we’re just getting better at observing these transient events…
Tonight is a very special night. Three celestial bodies clustered together in the sky, signifying a rare conjunction between the Moon, Venus and Jupiter. If you missed it, you’ll have to wait five years until the natural satellite of the Earth and two planets align in a similar pattern again in 2013.
Having been a frustrated astronomer for many years, I decided to get outside to investigate the conjunction over California for myself. Sure enough, from dusk, I could see a bright, thin crescent Moon with two very bright dots to the right and below in the southwest. The same scene has been repeated across many nations, but from my perspective I was able to capture the moment with some basic equipment and a very steady hand (plus some folded business cards)… Continue reading →
Is it me, or does virtually every robotic foray into space have some ET-searching component attached? In the case of Mars exploration, every lander and rover’s prime directive is find life, evidence of past life, potential for life or the building blocks of life. Even the very first man-made artefact to land (crash) on the planet, the 1971 Soviet Mars 2 mission, was designed to find organic compounds and… any sign of life.
