Space Station Flare Captured On Film

I’ve been watching this short video clip over and over. It may only be two seconds long, but it is such a unique view of the space station that I find it mesmerizing. Each time the animated GIF loops, another detail seems to reveal itself.

It’s also kinda hypnotizing in a rhythmic way; the space station appears to turn and boost away into the black of space, but just before its massive solar arrays capture the sunlight, dazzling the observer with a flash.

Is it me, or are those solar panels reminiscent of the sails hoisted up the masts of canon-touting battleships before the age of iron-hulled vessels and steam-powered engines? These slightly fuzzy images could even be from the turn of the 20th Century, when one of the first movie cameras filmed a ship steering out of port.

Of course, this isn’t a wooden ocean-going ship, it’s the space station, in orbit. And the video was taken with a modern digital camera through a 16-inch Dobsonian telescope by a highly skilled amateur astronomer called Nicolas Biver from Versailles, France. The reason why the station appears to “turn” is because the perspective of the observer changes as the station flies overhead, he did a great job of tracking it.

On April 28th, Biver tracked the space station through his ‘scope. Whether it was intentional or not, he was fortunate to capture an intense flare as the space station’s solar panels reflected sunlight at his location. The resulting flare was much brighter than Venus (after the Moon, the station is the second brightest object in the night sky). Usually when I hear about observations of flares made by stuff in orbit, I usually think of Iridium flares that occur at predictable times and locations, providing a target for observers on the ground to capture a meteor-like streak across the sky. The Iridium satellite network provides a great chance for astronomers to see the reflected light when the angle between them, the satellite’s solar panels and Sun is just right.

My astronomer friend Tavi Greiner (who has just joined the Astrocast.TV team as host of Our Night Sky, be sure to check it out!) is very skilled at observing the Iridium flare-ups, and as can be seen in this image, those things are bright.

However, on the 28th, it was the space station’s turn to reflect some light for Nicolas Biver.

In March, Space Shuttle Discovery completed the construction of the ISS solar arrays during the STS-119 mission. Over a series of space walks, the solar array had its area boosted to 16,000 square feet. With this extra surface area, comes the potential for very bright flaring events.

In 1911, Martians Were Building Canals

Martians Build Two Immense Canals In Two Years

On August 27th, 1911 the New York Times Sunday magazine ran an article entitled “Martians Build Two Immense Canals In Two Years”. Astronomer Percival Lowell had been studying the Red Planet and sketched what he saw, in this case, a growing complex of apparent canals on the Martian surface. There was even a nice little story that went along with this canal-building alien civilization theory. Lowell said, “The whole thing is wonderfully clear-cut,” that the Martian civilization was dying and they were building canals to reach the water ice in the Martian poles.

It turns out he was right about the water ice, but there’s no trace of this canal-building race on Mars… in fact there’s little trace of anything biological on the Red Planet. So apart from a few historic anecdotes, there’s still no life on Mars. The search continues.

Canals a thousand miles long and twenty miles wide are simply beyond our comprehension. Even though we are aware of the fact that … a rock which here weighs one hundred pounds would there only weigh thirty-eight pounds, engineering operations being in consequence less arduous than here, yet we can scarcely imagine the inhabitants of Mars capable of accomplishing this Herculean task within the short interval of two years. — Excerpt from the 1911 New York Times article.

Mystery Blob Detected 12.9 Billion Light Years Away

The Himiko object, the most massive object ever discovered in the early universe (M. Ouchi et al.)

Take a good look, this is one of the most mysterious, massive objects ever discovered in the cosmos. We don’t really know what it is, but this thing is huge, spanning 55,000 light years across (the approximate radius of our Milky Way). What makes this all the more intriguing is the fact that this object formed only 800 million years after the Big Bang and it is 10 times more massive than the next biggest object observed in the early Universe. But what is it?

Are Brown Dwarfs More Common Than We Thought?

A brown dwarf plus aurorae (NRAO)

In 2007, a very rare event was observed from Earth by several observers. An object passed in front of a star located near the centre of the Milky Way, magnifying its light. Gravitational lensing is not uncommon in itself (the phenomenon was predicted by Einstein in 1915), but if we consider what facilitated this rare “microlensing” event, things become rather interesting.

News just in from Gia Milinovich via Twitter:

Physicist and broadcaster Brian Cox presents a tribute to his science hero, the American astronomer Carl Sagan, the man who many people describe as the greatest populariser of science of all time. His landmark television series Cosmos was seen by more than 600 million people worldwide and inspired a generation of young scientists to regard the universe with wonder and awe. — Synopsis about Brian’s show on BBC Radio 4

I’m a huge fan of Brian’s work, he’s a fantastic and entertaining communicator of all things scientific, so this is the perfect tribute to legendary astronomer and presenter, Carl Sagan. I’ll be sure to tune in… with my late-morning coffee. According to Gia, Brian thinks this is the best show he’s done, so if that’s anything to go by, this is one event you cannot miss!

Catch the BBC Radio 4 stream at 8pm GMT (in the US, that’s midday PST or 3pm EST).

We are a way for the Cosmos to know itself.” –Carl Sagan

WR 104: Not The Killer It Used To Be

WR 104. A killer? Not so much.
WR 104. A killer? Not so much.

It’s interesting how astronomical harbingers of doom have the ability to pop up more than once on the ‘net. However, the doom isn’t quite as terrifying when you’ve sat through a conference presentation by a scientist who has exhaustively given every reason as to why this particular killer won’t hurt you.

Enter WR 104.

To be honest, if it wasn’t a Wolf-Rayet star, I probably wouldn’t be writing about it (as we all know, or you should know, Wolf-Rayets are my favourite stellar objects), but this little fact combined with the fact that I know the Earth is no longer on the WR 104 hit-list, I feel compelled to correct an article that has just popped up on the web referencing out-of-date source material.

So, let’s wind this back the clock to January 2009 when I sat in on a very reassuring this-star-isn’t-actually-going-to-kill-us-after-all astro presentation…

Listening Out for the Magnetospheres of Habitable Exoplanets

Is there a new way to hunt for habitable Earth-like exoplanets? According to a US Naval Research Laboratory researcher there is an obvious, yet ingenious, way of listening for these worlds. Like most Earth-like exoplanet searches, we are looking for characteristics of our own planet. So what do we need to survive on Earth? Obviously we need water and the correct mix of oxygen with other atmospheric gases, but what about the magnetic bubble we live in? The Earth’s magnetosphere protects us from the worst the Sun can throw at us, preventing the atmosphere from being eroded into space and deflecting life-hindering radiation.

Although we have yet to develop sensitive enough radio telescopes, it may be possible in the future to detect the radio waves generated as charged particles in stellar winds interact with Earth-like exoplanetary magnetospheres. If there’s a magnetosphere, there may be a protected atmosphere. If there’s an atmosphere, perhaps there’s life being nurtured below

Here’s One We Didn’t Discover Earlier

What’s just as exciting as directly imaging an exoplanet in a new observing campaign? To discover an exoplanet in an old observing campaign.

Like so many significant astronomical discoveries, archival images of the cosmos provide a valuable tool to astronomers. On its most basic level, astronomers can compare new images with images taken by the same (or different) observatory months, years or decades ago. This method can lead to the discovery of planets, asteroids and comets (when comparing two pictures of the night sky, a celestial object appears to move relative to the background stars). However, a new technique to analyse archived Hubble data in the search for exoplanets, has just revealed one of three known exoplanets orbiting the star HR 8699. The image in question was captured in 1998, when astronomers thought HR 8799 was an exoplanet-less star

“FAR” (the 365 Days of Astronomy Theme Tune) by George Hrab

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.

However, it all changed last month, when I met George Hrab. I’ve known about George for a while, but I only knew of his writing on Geo-Logic and that he was a musician. I had only heard the first couple of the 365 Days of Astronomy podcasts and I noted that they had one hell of a catchy theme tune. However, I didn’t give it any thought until I was introduced to George Hrab at the AAS in Long Beach last month. Ahhh, that George Hrab!

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)…

Watch the video above, or you can download the full mp3 from George’s blog. Enjoy!

Carnival of Space Week 88 – The Spacewriter


Want to know what’s been happening in the Universe this week? Get over to Carolyn Collins Petersen’s space and astronomy blog (a.k.a. “The Spacewriter”) for a SUPERB Carnival of Space. I’m not entirely sure where to start for week 88, there’s so much to choose from! In fact, looking at the number of entries, I’d say this is one of the largest turnouts so far. Wow, there’s a lot of science writing going on!

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):

21st Century Waves (Bruce Cordell): Long Waves and the Future of Human SpaceflightWow

Centauri Dreams (Paul Gilster): A Workable Fusion Starship?Whoosh!

Space Video of the Day: Announcement by Pres. Regan after the Challenger disasterMoving

Mang’s Bat Page (David Gamey): How You Could Pilot a Space Telescope (Upside Down)Shiny!

Simostronomy (Mike Simonsen): Aperture FeverObsessed!

The Martian Chronicles (Ryan Anderson): The MOC “Book”: IntroductionInsightful

Starts With A Bang! (Ethan Siegel): Supernovae and Dark Energy: Part IIAha!

There are loads more where that came from, so get your bums down to The Spacewriter and enjoy!

From, I submitted my musings about the secret payload on that Delta IV Heavy… just why are clandestine launches so damned sexy?
