Construction complete on the world's largest radio telescope in China


With the installation of a final triangular panel on July 3, 2016, construction has been completed on the gargantuan Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Dawodang, Kedu Town, Guizhou Province, China. Upon commencing operations in late September, the 1.5 billion yuan (US$ 180 million) FAST telescope will become the most powerful single-dish radio detector in the world.

* * *

Dawodang, Kedu Town was eventually selected as the site of the radio telescope in no small part thanks to the presence of the surrounding mountain formation, which will act to sheild FAST's delicate instrumentation from local radio disturbances.

* * *

"FAST will enable Chinese astronomers to jump-start many scientific goals, such as surveying the neutral hydrogen in the Milky Way, detecting faint pulsars, and listening to possible signals from other civilizations,"

White Dwarf Lashes Red Dwarf with Mystery Ray

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.

The star system AR Scorpii, or AR Sco for short, lies in the constellation of Scorpius, 380 light-years from Earth. It comprises a rapidly spinning white dwarf [2], the size of Earth but containing 200 000 times more mass, and a cool red dwarf companion one third the mass of the Sun [3], orbiting one another every 3.6 hours in a cosmic dance as regular as clockwork.

In a unique twist, this binary star system is exhibiting some brutal behaviour. Highly magnetic and spinning rapidly, AR Sco’s white dwarf accelerates electrons up to almost the speed of light. As these high energy particles whip through space, they release radiation in a lighthouse-like beam which lashes across the face of the cool red dwarf star, causing the entire system to brighten and fade dramatically every 1.97 minutes. These powerful pulses include radiation at radio frequencies, which has never been detected before from a white dwarf system.

I do not see this as a bad thing just because it was created by the Chinese, the US has a far worse track record of using technological developments to their geopolitical advantage. It is the advancement of science and that used in a neutral way can only be a good thing.

I don't think anyone was worried about that radio telescope. It's a good thing.

Alien Megastructure? Remains of a disintegrating planet? Comet swarm? Dyson Sphere?

What the heck is going on with Tabby's Star?

The So-Called Alien Megastructure Just Got Even More Mysterious

Heavyall was, at least by the tone of his post. I guess you missed that.

And no I don't think it was a joke.

Ian Flemming movies ware always about the "good" guy vs. the "bad" guy, so no I don't think it is any stretch of imagination to think that heavyall was thinking that way.
