Latest post of the previous page:

OK, did not spot the Youtube link the first time, thought you had yo download an app - trying not to fo that for temp stuff.

Nice, just a bit too fast for me at "normal" zoom speed. Also looked rather like one was just travelling away and seeing more distant objects. Tad confusing to one without lots of insight already built in!

Therevwas something on TV years ago where the view enlarged 10X per step, though there must have been lots of seemingly empty steps.

There are three fundamental questions for anyone advocating Brexit:

1. What, precisely, are the significant and tangible benefits of leaving the EU?
2. What damage to the UK and its citizens is an acceptable price to pay for those benefits?
3. Which ruling of the ECJ is most persuasive of the need to leave its jurisdiction?

Almost a science video... Google’s DeepMind AI can lip-read TV shows better than a pro

Or should this be in the 'Big Brother is reading your lips' thread?

Did you see the first programme in David Attenborough's superb Planet Earth 2? Here's a scene from it showing a marine iguana escaping snakes, dubbed into Scottish. Extremely NSFW!

Only three seconds-worth of video, but wow!

A Four Planet System in Orbit, Directly Imaged and Remarkable
The black circle in the center of the image is part of the observing and analyzing effort to block the blinding light of the star, and thus make the planets visible.

The images were initially captured by Dr. Christian Marois of the National Research Council of Canada’s Herzberg Institute of Astrophysics. The movie animation was put together by Wang, who is part of the Berkeley arm of the Nexus for Exoplanet System Science (NExSS), a NASA-sponsored group formed to encourage interdisciplinary exoplanet science.

The star HR 8799 has already played a pioneering role in the evolution of direct imaging of exoplanets. In 2008, the Marois group announced discovery of three of the four HR 8799 planets using direct imaging for the first time. On the same day that a different team announced the direct imaging of a planet orbiting the star Fomalhaut.

This false-color composite image traces the motion of the planet Fomalhaut b, a world captured by direct imaging. (NASA, ESA, and P. Kalas, University of California, Berkeley and SETI Institute)
HR 8799 is 129 light years away in the constellation of Pegasus. By coincidence, it is quite close to the star 51 Pegasi, where the first exoplanet was detected in 1995. It is less than 60 million years old, Wang said, and is almost five times brighter than the sun.

Wang said that the animation is based on eight observations of the planets since 2009. He then used a motion interpolation algorithm to draw the orbit between those points.

Wow indeed! Thank you for that.

The imaging of exoplanets has been likened to standing at Lands End, attempting to image a moth in orbit around a New York streetlight.

That could well be right - the resolution is remarkable.

It'll take less than 5 minutes to watch this remarkably erudite appeal to sanity from Neil deGrasse Tyson. This is exactly why I give my 'Pseudoastronomy' talks.
