Science & Reason on Facebook: tinyurl.com The Hidden Universe (Episode 20): Cassiopeia A – Echoes of a Supernova A supernova flash echoing through surrounding dust clouds has given astronomers a virtual time machine for studying the light from the explosion that nobody saw. This is the Hidden Universe of NASA’s Spitzer Space Telescope, exploring the mysteries of infrared astronomy with your host Dr. Robert Hurt. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — It’s the 17th century supernova that nobody saw, but telescopes in space and on Earth have teamed up to look back in time and study it today! When a massive star reaches its end of days it explodes dramatically and, for a few months, can outshine anything else in the galaxy. Earlier supernovas had been seen by many, often shining brighter than the planets. Of course with no witnesses, and no records, it’s difficult to tell exactly what kind of supernova it was. A team led by astronomer Oliver Krause has, over the last few years, made a remarkable series of infrared observations of the region. These Spitzer Space Telescope images show shifting patterns of glowing dust beyond the remnant itself. These changes are so fast that they indicate motion at the speed of light! To get what’s happening we have to remember that light moves fast, but in such a vast galaxy it still takes a while for it to get anywhere. Cassiopeia A (Cas A) itself is about 11000 …

On 2nd July 1967, a satellite picked up a huge burst of gamma rays. Was it evidence of a nuclear bomb test in space? Or was it from a much bigger explosion in deep space? Can Einstein’s famous physics equation E=MC2 help? Watch this video from BBC science show ‘Death Star’ to find out more.

more practice, would be better if I had made the background instead of using a pic

NASA’s Spitzer Science Center: “Ask An Astronomer (Part 1) The Center Of The Universe”. In this popular video series, real astronomers answer common questions about astronomy. Part 1: “Where Is the Center of the Universe?” Dr. Varoujan Gorjian explains the mind-boggling expansion of the Universe. — Subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com — Where is the center of the Universe? This may seem like a simple question. Since the Universe is expanding, it would seem logical that it was expanding away from a particular point. But, the Universe doesn’t actually work like that. The Big Bang, which started the expansion of the Universe, isn’t like a firecracker explosion where there is a boom and all the pieces go flying apart from a single point. The Big Bang was in fact the creation of matter and space. And it is this space that’s expanding. Think of space as if it’s a sidewalk with people standing on it. The expansion of the Universe isn’t the people walking away from each other, but it’s more like the sidewalk is spreading and moving the people apart. As a simpler example, let’s take the surface of a balloon. We can draw galaxies on it, but notice that no galaxy is at the center of the surface. When we blow up the balloon, all the galaxies spread apart from each other. If you look at any single galaxy, all the other galaxies seem to be spreading away from it. Every galaxy sees itself as the center of the expansion. But since not …
