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."

    The abuse is mostly done through moderation so staff can say it is the community deciding things instead of staff. They did give permission to spam mod aristarchus posts, so anyone criticizing soylentnews is now aristarchus and spam mods flow freely. It is pretty disgusting behavior and part of why this place is almost a ghost town. But of course it is all the criticisms of batshit crazy rightwing nonsense that are the real problem, according to janrinok anyway. Oddly janrinok claims to detest runaway's bullshit but I would then like to see janrinok's moderation history. For some reason old boomers never take even fake internet points action against rightwingers, or just call out the detestable posts. Nope, it is all the meanie pants people driving away the white supremacists /lawl
