Finding out the color was added to the Horsehead Nebula in post really killed my enjoyment of this kind of astrophotography as a purely asthethic experience. I still love the images for what they reveal but they do not capture the imagination for me like they should.

A similar thing happened when I found out about airbrushing and Playboy.

Those are all heavily processed composite images right? Or does Reddit lie?
Nope...you're dead on, as dodint alludes. Still a true (or as true as you can get) visual image of what you would see from that distance, however.

Angle of image data or reoriented? I believe the rings are at about a 45 degree angle, in relation to the plane of the solar system.

The angle doesnt matter, there is no up or down out there. Besides, our solar system is tilted 90ish degrees from the galaxy arm, so technically, uranus is the only "correctly" oriented planet.

Rainier weiss, barry barish, and kip thorne win the nobel prize for physics, for the detection of gravitational waves at the LIGO sites, opening a new field of physics and setting us up to discover the beginning of the universe.

I am so pumped i cannot explain.

Stunned Scientists Detect Suspected Hidden Chamber Within Great Pyramid of Giza
Though they were constructed nearly 5,000 years ago, the Great Pyramids of Egypt are still packed with secrets. Using a technique that leverages the power of cosmic rays, scientists have confirmed the presence of a large empty space within Khufu’s pyramid—a void that’s signaling the presence of a possible hidden chamber.

This is a pretty wild read theorizing the imminent death of the automotive industry with the rise of automated transportation.

Hes not wrong. The timeline may be off, and you might see more people ride-sharing their own "modules" versus Lyft/Uber getting the whole market, but it's coming. The question is when, not if.

Electric cars have been a big thing for a while now and they only account for like 1% of total sales. It’s going to be decades if anything like that ever happens.

I agree with this. But autonomous mainstream will be decades if ever.

Less if the manufacturers and fleets get their way. You'll be a dinosaur if you're driving your own tractor in ten. The average nationwide fleet (Werner, JB Hunt, YRC, etc) keep their tractors for three years. Recessions like 2008 stretch that a bit to 5 at the most. So in a worst case, you've got to assume autonomous technology wouldn't be accepted as viable, cheaper, and safer 5 years from now, despite Tractors being in test right now.

nobody, the adoption of electric cars has always been hampered by the nebulous "it's better for the environment" argument and range. They aren't better cars (nominally worse because of design concessions) and they aren't cheaper. Before Tesla they were gutless so their was no joy in operating one. You're only benefit was smelling your own farts (thanks South Park). With autonomous vehicles the driver is safety. I'm with Lutz that beyond line haul trucking, the first adopters will be services like USPS, UPS, Amazon, etc. Small sized vehicles in locally based fleets. From there it will snowball. It'll be hard to remove manually driven vehicles from the roadways though. You've got so many people dependent on their truck or that to run to Home Depot and get construction goods, haul a trailer to the lake, etc. Not to mention the immediate devaluation of a manually op vehicle if it occurred through legislation would no doubt create a large handout program for the owners of those dinosaurs.

This is awesome!! And the fact that it is in Cygnus is even better. It is visible in our night sky at one point or another all year long due to its northern declination. Thanks for sharing.

This reminds me; I was listening to NPR over the weekend, and one of the TED talks was regarding the new LSST telescope. They were saying they have found 45 or so supernovae over the past 3 years. With this new telescope, they will be able to find that many in an hour. When this new telescope is launched, it will change what we know about the world almost immediately. The problem is there will be so much data they won't be able to comb through all of it. Therefore, they are going to make all the images available to the public. So there's a good chance a large number of amateur astronomers will discover new galaxies/supernovae before the professionals do.

Bronze Age artifacts used meteoric iron
Albert Jambon gathered the available data and conducted his own nondestructive chemical analyses of samples using a portable X-ray fluorescence spectrometer. His collection of iron artifacts includes beads from Gerzeh (Egypt, −3200 BCE); a dagger from Alaca Höyük (Turkey, −2500 BCE); a pendant from Umm el-Marra (Syria, −2300 BCE); an axe from Ugarit (Syria, −1400 BCE) and several others from the Shang dynasty civilization (China, −1400 BCE); and the dagger, bracelet, and headrest of Tutankhamen (Egypt, −1350 BCE).
Pretty cool, IMO.

electric and hybrid cars have been fairly lousy throughout their entire existence up until recently. and currently, the ones that are quality are expensive. if a $20K telstra comes out, and handles like a gas guzzler, then electric cars will officially be a thing. they aren't a thing yet.

Super Blue Blood Moon

https://www.yahoo.com/news/blue-moon-su ... tml?exp=vv
On Wednesday, much of the world will get to see not only a blue moon and a supermoon, but also a total lunar eclipse, all rolled into one. There hasn't been a triple lineup like this since 1982 and the next won't occur until 2037.

The eclipse will be visible best in the western half of the U.S. and Canada before the moon sets early Wednesday morning, and across the Pacific into Asia as the moon rises Wednesday night into Thursday.

:thumbdown: The U.S. East Coast will be out of luck; the moon will be setting just as the eclipse gets started. Europe and most of Africa and South America also will pretty much miss the show.
