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."

    Let's get something straight to begin with. You are aristarchus, posting as an AC. Janrinok has already said the allegation is nonsense. See https://soylentnews.org/comments.pl?sid=53605&cid=1291397 [soylentnews.org]. This isn't the first time you've done shit like this. Remember these?

    Khallow's reply to the last comment was absolutely correct. We now know that you were behind the FYN accounts. Here are some links with to show this:

    You created the FYN accounts and modded up the APK spam. Then you posted about it alleging that an admin leaked the information to you. Of course, the actual reason you knew who modded up the APK spam is because you were doing it. Once you did this, you went on IRC to discuss the supposed leak: http://logs.sylnt.us/%23soylent/2021-11-20.html [sylnt.us]. Rehash improperly converts the %23 to a #, so the link doesn't go to the correct page. However, if you copy and paste the URL text into your browser, then scroll down to see this:

    [05:43:37] <GhostofAristarchus> Runaway is filled with ammosexual jism? Gross! And accusations of serially numbered Sockpuppets are appearing, with a claim of an admin leak? Hmm.

    You created the FYN accounts, modded up the APK spam, posted the supposed admin leak yourself, and then went on IRC to fuss about it. Given your history, you're probably also the supposed whistleblower here, referencing an email that you know doesn't exist. It certainly fits your mode of operation. You're no better than the people who make up conspiracy theories about things like vaccines, manufacture fake evidence, and then post about it online. When people don't want to waste their time refuting obvious bullshit, that is treated as more evidence supporting the bogus conspiracy theories. If that wasn't enough, you created a new batch of FYN accounts over the weekend, numbered 61-70. You're pretty much following the same playbook as copyright trolls who upload their own content to file-sharing services, then sue for piracy.
