In 2010, a 36-minute routine telescope session captured hidden giant rings in Venus' atmosphere: Archived images reveal mysterious planet-wide atmospheric waves after 16 years

In 2010, astronomers captured 36 minutes of Venus imagery while waiting for sunset in the Canary Islands. The data sat forgotten in archives for over a decade. Now, Dutch scientists re-analyzed those old files using polarized light filters. What did they find? Giant, planetwide concentric rings hiding in Venus's upper atmosphere. The cause? Massive atmospheric gravity waves shifting local gas density by 5% to 10%.
