How Do We Know How Old Our Sun Is?

Beakus were commissioned to create three animated films that explain key concepts about our universe, with humour helping to explain the ‘almost’ unexplainable! Director Amaël Isnard also designed the films.
In ‘How Do We Know How Old The Sun Is?’ ROG astronomer Brendan explains how we determine the age of our Solar System from space rocks and how we can work out how long the Sun has left before it engulfs the inner planets.

Reality Doesn’t Exist If You Are Not Looking at It

According to a well-known theory in quantum physics, a particle’s behavior changes depending on whether there is an observer or not. It basically suggests that reality is a kind of illusion and exists only when we are looking at it. Numerous quantum experiments were conducted in the past and showed that this indeed might be the case.

Now, physicists at the Australian National University have found further evidence for the illusory nature of reality. They recreated the John Wheeler’s delayed-choice experiment and confirmed that reality doesn’t exist until it is measured, at least on the atomic scale.

In ‘What’s Inside A Black Hole?’ ROG astronomer Rad explains where black holes come from, how we know they’re there and the strange effects they have on surrounding matter. We also find out what would happen if ROG astronomer Liz approached one!

Maybe Earth Was Born Too Early?!

BetaPic_fromNASA_web_1024
At roughly 13.8 billion years old, the Universe might seem like it’s been around for a long time, but a new study suggests that Earth is one of the first habitable planets to form – and we’re probably too early to the party to get a chance to meet future alien civilisations.

The research looked at data from the Hubble and Kepler space telescopes, and predicted that 92 percent of the Universe’s habitable planets have yet to be born. And most won’t form until after our Sun burns out in 6 billion years’ time.

Final Kiss of Two Stars Heading for Catastrophe

VLT finds hottest and most massive touching double star
21 October 2015

two-stars-kissing

Using ESO’s Very Large Telescope, an international team of astronomers have found the hottest and most massive double star with components so close that they touch each other. The two stars in the extreme system VFTS 352 could be heading for a dramatic end, during which the two stars either coalesce to create a single giant star, or form a binary black hole.

The double star system VFTS 352 is located about 160 000 light-years away in the Tarantula Nebula [1]. This remarkable region is the most active nursery of new stars in the nearby Universe and new observations from ESO’s VLT [2] have revealed that this pair of young stars is among the most extreme and strangest yet found.

VFTS 352 is composed of two very hot, bright and massive stars that orbit each other in little more than a day. The centres of the stars are separated by just 12 million kilometres [3]. In fact, the stars are so close that their surfaces overlap and a bridge has formed between them. VFTS 352 is not only the most massive known in this tiny class of “overcontact binaries” — it has a combined mass of about 57 times that of the Sun — but it also contains the hottest components — with surface temperatures above 40 000 degrees Celsius.

The Known Universe

Uploaded on Dec 15, 2009
The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world’s most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

FAQ:

What is that blue square near the end?
It’s the river/moat around the temple of Angkor Watt in Cambodia.

Is every detail accurate?
It’s an accurate guide to “the sort of thing” you would find. For example, real atoms are basically full of empty space, but I showed a lot of crazy patterns because there are quantum fluctuations and probability fields that make atoms fascinating links to infinite possibilities.

Can you make a video that zooms into something else?
Yes! I can change the person for sixty dollars, or a complete new video costs a thousand dollars. That is only a fraction of what it costs me to make it, assuming I pay myself minimum wage. A full video like this requires fifty high resolution images, and each one a day to find (because I need royalty free images at far below commercial rates). Then another day to edit seamlessly into the next image. Then the completed video takes a couple of weeks to put together, mainly because Blender is not designed for stuff like this and it takes ages to tweak those spline curves. It really needs Adobe AfterEffects, but that costs a fortune. So each new video takes four month’s skilled work. But I’m happy to do it if you want to pay!

This video uses three pieces. In order, they are:
“Haunting” by Matthew Milne of Logan Leistikow’s Public Music Project. The PMP was a site devoted to providing free (and royalty free) music for projects like this. Milne confirmed by email that he is happy for me to use this piece. He’s a great guy.

“Tenebrous Brothers Carnival – Mermaid” and “Long Road Ahead” by Kevin McLeod of http://Incompetech.com. McLeod is the patron saint of poverty stricken YouTubers, providing quality, royalty free music at no charge. Visit his site!

Music was merged using Audacity. Audacity and Blender (and the Gimp for the art) are free and open source.
