This is your Astronomy Tonight podcast.
On this day in astronomy, August 27th, we celebrate the anniversary of a truly electrifying discovery. Back in 1989, the Voyager 2 spacecraft made its closest approach to Neptune, becoming the first and so far only spacecraft to visit the distant ice giant.
As Voyager 2 zipped past Neptune at a blistering speed of about 60,000 kilometers per hour, it captured unprecedented images and data about the planet and its moons. One of the most jaw-dropping findings was the detection of what scientists playfully dubbed the "Great Dark Spot," a massive storm system in Neptune's atmosphere comparable in size to Earth itself!
But the excitement didn't stop there. Voyager 2 also unveiled Neptune's wildly dynamic weather patterns, with wind speeds clocking in at a mind-boggling 2,100 kilometers per hour – the fastest in the solar system! It's like Neptune decided to throw a cosmic hurricane party, and Voyager 2 crashed it in style.
The mission also revealed the existence of Neptune's faint ring system and discovered six new moons orbiting the planet. Talk about a family reunion! Neptune went from having two known moons to a whopping eight in one fell swoop.
This close encounter with Neptune marked the grand finale of Voyager 2's "Grand Tour" of the outer solar system, a journey that began way back in 1977. It's mind-boggling to think that a piece of technology launched when disco was still king is still out there, now exploring the very edge of our solar system.
So the next time you look up at the night sky and spot that faint blue dot that is Neptune, remember the little spacecraft that could, and the incredible discoveries it made on this day in 1989.
