Earth isn’t the only world in our solar system with an ocean! In honor of #ArchivesUnderTheSea, here are a few of our favorite extraterrestrial oceans in a thread ⬇
Saturn’s largest moon Titan is thought to have a large liquid ocean trapped under its outer layer of ice. So, what’s “Under the Sea”? Methane, apparently. Scientists believe this ocean stores and releases the methane necessary to resupply Titan’s methane-dominant atmosphere.
Scientists point to bright spots on the surface of the dwarf planet Ceres as evidence of a subsurface ocean. These bright spots are actually reflective salt deposits, likely left behind after water from the briny ocean made its way to the planet’s surface and evaporated.
Like its sister moon Titan, Saturn’s moon Enceladus contains a vast ocean beneath its icy crust. This water shoots up into Enceladus’ atmosphere from cracks in its surface and creates dust, some of which is pulled into Saturn’s outer ring.

We hope our Twitter feed brings you moments of joy and inspiration during these uncertain times. So, every day in April, we’re going to post an incredible space photo that brings us awe. (And we’d gladly take recommendations!)
This photo of the gas giant's southern hemisphere was taken by the Juno spacecraft and processed by citizen scientists Gerald Eichstädt and Seán Doran: s.si.edu/3dTvIKG
Astronauts on board the International Space Station get to view auroras from a unique vantage point. This photo of the northern lights (aurora borealis) above Canada was taken by an ISS astronaut in 2012: s.si.edu/3bPXnu1
🙋♀️Raise your hand if Wikipedia is one of the first places you go to find information. (Don’t worry, you’re not alone.)
Today, we hosted an edit-a-thon to increase the information about women on Wikipedia and make sure that information is accurate and sourced. #BecauseOfHerStory
We added lots of information and photos. We also created a dozen new Wikipedia articles for women in STEM, like Baerbel Lucchitta, an astrogeologist who helped make the lunar maps for the Apollo 11 mission: en.wikipedia.org/wiki/Baerbel_L…#Apollo50#BecauseOfHerStory
Until now, there wasn’t a public domain image of astronomer Phoebe Waterman Haas, so museum educator Diane Kidd, who is also an illustrator, created a portrait of her live during our event. It's now on Phoebe's Wikipedia entry: en.wikipedia.org/wiki/Phoebe_Wa…#BecauseOfHerStory
July 16, 1969, three astronauts departed on a mission that would captivate the world. In celebration of #Apollo50, we're counting down to the launch of #Apollo11 by sharing an artifact each day that tells the story of our journey from Earth to the Moon.
The artifacts we will be highlighting — big and small, critical and amusing, familiar and never-before-seen — are expanded on in the new book "Apollo to the Moon: A History in 50 Objects" by National Air and Space Museum curator Teasel Muir-Harmony. #Apollo50
Yesterday marked 50 days to #Apollo11 launch, so let's start at the beginning of the Space Race: the failed launch of the Vanguard TV-3 satellite in December 1957, a response to the Soviet Union's Sputnik success two months earlier: s.si.edu/2iYQ0e9#Apollo50
