Raise your cosmic sails ⛵ This #HubbleFriday image shows the galaxy NGC 3318, which is part of the constellation Vela…which was originally part of a much larger constellation known as Argo Navis after the ship Argo from Greek mythology! Read more:

See those blue-white dots? They aren’t just stars – they’re star clusters, and this #HubbleClassic image is full of them. We can tell they aren’t stars because their brightness is too great, considering the galaxy is 250 million light-years away:

Sure, black holes might get a bad rep for being hungry, destructive monsters… But Hubble found evidence of a black hole creating stars rather than destroying them! Learn more:

☃️ Guess what? It’s #WorldSnowmanDay ! The Snowman Nebula is about 6,000 light-years from Earth in the constellation Puppis. Hubble’s view captures sweeping curves of bright gas and dark knots of dust. Learn more about this beautiful nebula:

Did you know Hubble helped build @NASAWebb ’s “to-do” list? ☑️ One of Webb’s upcoming projects is called COSMOS-Webb, which will observe a patch of sky containing half a million galaxies – building on a huge survey that Hubble started in 2002. Learn more:

You’ve heard of spiral galaxies… but have you heard of prototypical barred spiral galaxies? Now you have! This #HubbleClassic image shows NGC 1672, a galaxy with spiral arms that attach to two ends of a bar of stars that enclose the galaxy’s nucleus:

Building on a classic ⭐ When it launches in 2027, @NASARoman will make wide observations of our universe with its enormous field of view. One such observation could build upon Hubble's iconic Ultra Deep Field image, as seen simulated here! More:

We’ll leave you to *reflect* on all that. Hubble & Webb, with their complementary abilities to see across the electromagnetic spectrum, will work together to give us a more complete view of the universe. Learn more:

Temperature 🥶 Hubble is optimized to observe ultraviolet & visible light, so its primary mirror doesn’t have to be as cold as Webb’s. But to detect faint infrared light, Webb’s mirrors have to be around -364 degree F! (Image shows mirrors getting prepped for cyrogenic testing)

Hubble’s primary mirror is made of one large piece of Ultra-Low Expansion Glass® that is coated with thin layers of aluminum and magnesium fluoride. Webb’s 18 mirror segments are covered in a thin, reflective layer of gold, which reflects infrared light more efficiently.
