Stunning new time lapse video shows 12 years of exoplanets orbiting their star:

In 2008, HR8799 was the first extrasolar planetary system ever directly imaged. Now, the famed system stars in its very own video.

Using observations collected over the past 12 years, Northwestern University astrophysicist Jason Wang [northwestern.edu] has assembled a stunning time lapse video of the family of four planets — each more massive than Jupiter — orbiting their star. The video gives viewers an unprecedented glimpse into planetary motion.

"It's usually difficult to see planets in orbit," Wang said. "For example, it isn't apparent that Jupiter or Mars orbit our sun because we live in the same system and don't have a top-down view. Astronomical events either happen too quickly or too slowly to capture in a movie. But this video shows planets moving on a human time scale. I hope it enables people to enjoy something wondrous."

[...] In November 2008, HR8799 made history as the first system to have its planets directly imaged. Wang, who was instantly fascinated by the system, has been watching it ever since. He and his colleagues applied for time on the W. M. Keck Observatory, located on the top of Mauna Kea in Hawaii, to observe the system each year.

After seven years of observations, Wang put together imaging data to create his first time lapse video of the system. Now, armed with 12 years of imaging data, Wang released the updated video, which shows the entire time period in a condensed 4.5-second time lapse.

[...] "In astrophysics, most of the time we are doing data analysis or testing hypotheses," he said. "But this is the fun part of science. It inspires awe."

    It is a low effort troll. Why post the exact date but not the contents of the alleged email? I don't remember the exact date of any emails I sent or received five months ago. If the person can recall the exact date of the alleged email, it suggests they probably still have access to view said email and could post its contents. That would let people analyze writing patterns to ascertain the likelihood of authenticity. The person posted it as an AC and didn't identify themselves, suggesting a desire to remain anonymous. But they were foolish enough to narrow the pool of possible suspects by indicating that they were a staff member on September 10 but resigned during the past five months. Even a bit of common sense makes it clear that this is likely a lazy bit of trolling.

    As for your insinuation about my political views, here's another comment I wrote: https://soylentnews.org/comments.pl?sid=53676&cid=1291201 [soylentnews.org]. I'll let you decide for yourself if the views I express are what you'd expect from the alt-right. Your spamming, stalking, and harassment make people who share my views look bad. For that matter, Azuma Hazuki supports your political views but has slammed your actions. You claim that you got banned for criticizing the alt-right. In fact, you hadn't actually criticized the alt-right for months prior to your banning and had turned to full time spamming. The personal attacks and harassment directed at Runaway after your ban aren't criticisms of the alt-right, either. If you had stuck to actually criticizing the alt-right instead of going off the deep end of staking, you wouldn't have been banned.

    You claim that janrinok is a right winger, too. In fact, he's criticized the right far more than you have over the past year. He's slammed some of Runaway's opinions. You, on the other hand, seem to just post content-free personal attacks when you're not pouting about your ban.
