Not everything that twinkles in the night sky is a star or a planet. Satellites have the same basic appearance as stars and unless you’re looking at them for a long time, the human eye cannot tell the difference. If, on the other hand, you’re pointing your camera set for time lapse into the sky, you can see distinct differences in the way they appear. The ones in the video below are geostationary satellites that are easily seen when contrasted against the stars in their background. Taken from one of the highest revolving restaurants in the world at Mittelallalin in the Swiss Alps, the video makes a visually…

Does your brain hurt right now? Unless you’re an astrophysicist, watching the video below should make your brain hurt if it isn’t already. The universe is an amazing thing, expanding and shifting in ways that make measuring the distances between stars and galaxies extremely complex. It’s not a one-step process – all of the data from different forms of distances measurement must be combined to form a broader picture of how far objects are from the Earth. That’s the gist. The video goes into much more detail but not so much detail that you need to (literally) be a rocket scientist to understand it….

There are fears in the scientific community about coronal mass ejections (CMEs) and our recent inability to track them properly. CMEs are huge magnetized clouds of electified gas (plasma) that can be as big as 1.5 trillion tons of gas and travel at 3 million mph. If a powerful CME hits the earth’s magnetosphere, it can disrupt salellites, radio communication, and even the electric grid. The head on perspective of tracking CMEs from earth has always offered a challenge. As you’ll see in this video, a combination of new technologies makes it possible to have better understanding of the events. For…
