“At the end of this talk, you won’t know anything new than you knew in the beginning” Dr Paul Francis said. “Greatest Unsolved Mysteries of The Universe” is the title of his first public lecture in 2010. I hope you will enjoy this.
This public lecture was co-organized by ANU Black Hole Society and Australian Institute of Physics. The video is provided by Australian National University Channel at YouTube.
NASA Solar Dynamics Observatory (SDO) has beamed back jaw-dropping images of the sun and they have been released on 21 Apr 2010. There is a video with the prominence above in high definition (HD) at First Light of the Solar Dynamics Observatory which you must not miss. Even experienced solar physicists said that they learned new things by just watching the videos.
There are also videos showing solar flare and magnetic field on the sun surface.
Offtopic: Talking about HD, the hype is almost everywhere. Sooner or later, there might be HD eyepieces, HD mounts, HD bla bla bla…
The ABB FlexPicker Robot arm can accelerate at 10Gs which allows it to reach 280mph from zero in one second. Isn’t this very terrific? Not only that the arm is fast enough, the precision of the system is also jaw-dropping. Watch the video and you will know how cool this robotic arm is.
Astronomically, I do not think that ground based observatories need such high speed system as the dominant factor lies in the imaging duration. However, space based observatories which are excelled at the gamma rays burst observing can benefit from such speed as the gamma rays burst usually do not last long. With such high speed system, more time can be spent on imaging rather than navigating.
The UK Minister for Science, Lord Drayson, gave an opening address at the European Week of Astronomy and Space Science meeting held last week at the University of Hertfordshire, UK. The Minister spoke to Astronomy Now, an IYA2009 Media Partner, about why he thinks astronomy is important.

After watching Carl Sagan’s Pale Blue Dot, we’re sure to feel how small we are. Think wider, not to quarrel over a small matter, be wiser and live harmoniously on our only dot.
