News re. #JWST:

The team has decided to delay tensioning of the sunshield to tomorrow (January 3), to give themselves more time to better understand how the observatory is actually behaving in space, and to allow the tensioning motors to reach optimum temperatures.

how it started: how it's going:

Left: Tropical Storm #Isaias at 6:51 pm EST today, seen by @NOAA's GOES-16 satellite.

Right: Storms on Jupiter seen by @NASAJuno and processed by Gerald Eichstädt and Seán Doran (@_TheSeaning)

Eh, planetary ring people... is this comic by @ZachWeiner true??

Your periodic reminder that there is a giant, swirling vortex at Saturn's north pole that's about 1,600 km across and it will kill you if it can.

Thank you, @theNASciences!

Jupiter, as seen by @NASAJuno about a week ago, and processed by @kevinmgill.

Look at those swirling clouds, storm after storm, those endless bands of clouds—folks, Jupiter is BEAUTIFUL

Now things get *really* interesting—Catherine Johnson (@UBC) et al. have measured #Mars' magnetic field at the landing site, finding that it's *ten times* stronger than predicted, consistent with an ancient dynamo as strong as Earth's field today!!

Folks—

Heading home from the #BackyardExoplanets meeting, I'm thinking a lot about #Venus—the #exoplanet just next door—and of these images of the night side of Venus...

...that show the ultra-hot surface GLOWING through the clouds

😮😍
