Rings

May 25th, 2015

Emily Lakdawalla's dive into the latest batch of images from the Cassini probe inspired her to generate a magnificent panorama across Saturn's rings (scroll down to the foot of the article.)

Gigantic rings

January 26th, 2015

Staying on the theme of what a big universe it is, astronomers think they've spotted a planet with a seriously big ring system:

"The star is much too far away to observe the rings directly, but we could make a detailed model based on the rapid brightness variations in the star light passing through the ring system. If we could replace Saturn's rings with the rings around J1407b, they would be easily visible at night and be many times larger than the full moon."

Replacement stars

January 26th, 2015

If the Sun were replaced by some other stars.

Be sure to watch to the end when we get to see Polaris up close. It's a hell of a thing.

I call it the Moonbase Alpha treatment

January 13th, 2015

Super Planet Crash is a solar system simulator game that just proved what an asshole I'd be if I was in charge of the universe. There I was with my 10-planet system, chugging along nicely past the 300-year mark and I got bored and added a brown dwarf to the inner solar system.

The result:

Bye bye, Planet 10

Oh well, how many Earth-sized planets does a solar system need, really? Besides, just think how much more of the universe the inhabitants of Planet 10 will see this way (until the atmosphere freezes as they wander the interstellar depths.)

Blackout City

December 7th, 2014

Blackout City by Nicholas Buer:

In a metropolis like London light pollution makes the night sky invisible. Only a few of the brightest stars and asterisms force their celestial light through the man made glow of the city. The night sky, one of the most beautiful of natural wonders is extinguished from view. Blackout City is an experimental timelapse film that makes the invisible, visible. It attempts to show what the night sky would look like If there were ever to be a total blackout in the South East of England on a clear, moonless, summer's night.

An extraordinarily large ring of fire

The situation could technically be labeled a Mercurian annular eclipse with an extraordinarily large ring of fire.

Best viewed in full screen mode at the highest available resolution.1

  1. Actually, that should read 'Best viewed in person.' But this video is the next best option.

  1. I have to admit that at first glance one of my thoughts was "That looks like it's the NCC-1701!" I know the 'saucer section' looks to be too far back but otherwise it fits, dammit!

Cosmos II

July 22nd, 2013

I was vaguely aware that Neil deGrasse Tyson was remaking Carl Sagan's Cosmos, but I hadn't given the project much thought. Now there's a trailer, so it's time to pay attention.

Full marks for good looking graphics – that shot of the sun shining through Saturn's rings is just glorious. There have been an awful lot of discoveries over the course of thirty-some years that render parts of Sagan's story obsolete or incomplete, but someow I can't see this having the sort of impact Sagan's original series did back in 1980, when there just weren't a lot of well-funded mainstream TV documentary series about space/astonomy etc.1.

In the wake of Brian Cox's career, how much mindspace is there for another epic space documentary series? Come to that, do we really need another series of eye candy? I hope Tyson and his script are up to the challenge and prove me wrong.2

  1. Yes, obviously, there was – and still is – The Sky at Night, but that wasn't the same thing at all.
  2. I freely acknowledge that I'm looking at this from a parochial, UK perspective. I'd just hate to see the BBC or Channel 4 stump up a ton of cash for the UK broadcast rights for this if it's only going to be pretty.

The Game Has Changed

June 6th, 2013

Yes, it's another time lapse video featuring lots of night skies and shining cities. But to my mind the way the images and the music1 combine makes The Game Has Changed a couple of steps up from the average nighttime time lapse video.
