Behind The Science: The Planetarium

How does a planetarium work? Where do the stars come from? Ross Exton takes you behind the science of the planetarium to find some things you would NEVER see on a regular visit to At-Bristol.

Real SCIENCE of zombies and resurrection - Sci Guide (Ep 13) - Head Squeeze

My first Sci Guide for Head Squeeze! I discuss whether or not it is scientifically possible to bring someone back from the dead.

Spring Night Sky 2013

Ross gives a tour of the Spring Night Sky, including the constellations Boötes, Leo and Ursa Minor, as well as the visible planets this season. Learn about the planet Saturn, its rings and some tips on finding it for yourself.

AQA - Which came first, the chicken or the egg?

In this episode of Any Question Answered, Ross Exton answers two questions from visitors to the science centre, At-Bristol:

‘When lightning strikes the sea, why don’t all the fish die?’
‘Which came first, the chicken or the egg?’

If you have any questions you want the answer to, tweet either Ross or At-Bristol with the hashtage #abAQA; one will be picked one to include in the next AQA to feature alongside the questions from visitors.

Beyond their pretty remarkable ability to “think” and problem-solve, slime molds are just plain beautiful.

John Bonner, a professor emeritus at Princeton, has been studying them for seventy years. He’s been fascinated by the ability of this “bag of amoebae encased in a thin slime sheath” to operate like a simple brain, despite its biological simplicity. He’s used the gooey little guys to further the study of evolution and development for over half a century, and some of the images he’s collected are stunning.

The GIFs above are from this collection of half-century-old film clips captured by a young Bonner, showing the life cycle of a slime mold. Lastly, you absolutely do not want to miss this gorgeous new collection of close-up slime mold photos SciAm’s Alex Wild.

Old and new, these little creatures are as beautiful in form as they are amazing in biology.

Check my archive for today’s other slime mold posts!!

Bjӧrk’s new video for the song Mutual Core really makes me wish I had been a geologist. Sediments, rifts and eruptions … oh my!

Geologists always say rocks are sexy, but I never pictured this. Gneiss song, anyway.

The Nature of Origami

Bernie Peyton uses some of the best animal origami I’ve ever seen to call attention to threatened species and remind us that nature’s treasures (the living ones, not the paper ones) are worth protecting. Check out his gallery … I bet you can’t pick out a favorite!

July 20, 1969: First Man Walks on the Moon

On this day in 1969, the spaceflight Apollo 11 landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the moon.  People watched worldwide as Armstrong took that momentous first step onto the moon, declaring, “This is one small step for a man, one giant leap for mankind.”

One does not simply land on the moon wearing a t-shirt and jeans.  See how these Historic Space Suits evolved to allow a successful landing on the moon!

Mars images captured by Nasa’s rover Opportunity 

It could be the Sahara or Egypt’s Western Desert, but this sand-covered crater is the latest image from Mars.

The picture was taken from US space agency Nasa’s Mars exploration rover, Opportunity, close to where the robotic unit spent the winter analysing soil and air samples. The picture shows the explorer’s deck and solar panels, tracks it had previously made and a crater that was created by an impact billions of years ago.

Opportunity has now spent 3,000 Martian days on Mars (eight and a half Earth years), and Nasa has consistently had a robot there for 15 years. Mars Pathfinder landed on 4 July 1997; Nasa’s Mars Global Surveyor orbiter reached the planet while Pathfinder was still active; and Global Surveyor overlapped the active missions of the Mars Odyssey orbiter and Opportunity. The latter two are both still in service.
