Uranus & Neptune

News and facts from our ice giant friends, Uranus and Neptune. Hoping for a new mission! Make it happen @NASA/@ESA

[Uranus & Neptune @IceGiantsToday]

Which ice giant planet should we send an orbiter to first?

Sushil Atreya reviews launch windows for Neptune and Uranus missions. No matter how you cut it, arrival dates are post 2040. Better eat my wheaties and spend more time at the gym...

It’s standing room only at the Ice Giants splinter session! Lots of love for Neptune and Uranus systems ❤️🚀🔵 #epscdps2019

Louise Prockter @Louise_Prockter—Trident is a @NASA Discovery proposal to flyby Neptune’s moon Triton. The super close flyby would revolutionize our understanding of this former KBO, turned captured ocean world! #EPSCDPS2019

[Cassini @CassiniSaturn]

@NASAVoyager Neptune’s moon Triton circles the planet in a direction opposite to Neptune’s rotation, which suggests it's an object that the giant planet captured. Despite the extreme cold, Voyager 2 discovered geysers on Triton spewing icy material upward more than 5 miles (8 kilometers).

Throwback to a cool encounter 🔵

We’re coming up on the 30th anniversary of #Voyager2’s flyby of Neptune, which happened on Aug. 25, 1989: https://t.co/DBvPCcLwdA #tbt

[NSFVoyager2 @NSFVoyager2]

Govert Schilling (@govertschilling), in his first contribution to @SkyandTelescope, wrote in January 1990 about the experience of witnessing the Neptune/Triton encounter first-hand at @NASAJPL 30 years ago: https://t.co/woL9NoZc8I

Too busy to realize that ystrday marked 30 yrs since #Voyager2 flew past Neptune, the farthest planet in our solar system (tho we await Planet 9!)

It was a seminal moment in human history ...

[Carolyn Porco @carolynporco]

... and a life-defining one for me. The following year, I was chosen to lead the imaging team on Cassini & never looked back.

I've led a charmed existence.

Sromovsky et al. (2018) used @NASAHubble spectroscopy to study methane depletion at the poles of Uranus (south in 2002, north in 2015), and show that the brightening of the spring pole can be explained by increased scattering from tropospheric aerosols:

@johncarlosbaez And it may actually be the material that makes up the cores of the ice giants Uranus and Neptune

Trying to assemble a white paper on #IceGiants for an ESA call, and really struggling to find a decent infographic for Uranus and Neptune. So I cobbled one together from a variety of sources, hopefully it captures the incredible variety of these systems:

Uranus! And its moons! With background galaxies! In near-infrared! Click for original (high quality) gif:

If you were asked to name the Moon, what would you call it? We chose Hippocamp as the name for a mysterious tiny moon around Neptune discovered by our @NASAHubble Space Telescope. Discover more about “the moon that shouldn’t be there”: https://t.co/2LxGtdwZUu

The butt of many jokes, this week's #SpaceSaturday is taking a deep dive into Uranus. #Starstruck

Jovian close encounter. A multitude of magnificent, swirling clouds in #Jupiter's dynamic North North Temperate Belt is captured in this color-enhanced image: https://t.co/0lAAb7fqEK

[NASA's Juno Mission @NASAJuno]

Spotted: Massive waves in #Jupiter’s atmosphere.

JunoCam has detected atmospheric wave trains -- towering structures that trail one after the other as they roam the planet https://t.co/VhlAdTEMZL

Mark Hofstadter on the formation and interiors of Saturn and Uranus. “Ice giants are disturbing” 😂 #DPS18 #IceGiants @DPSMeeting

[Emily Lakdawalla @elakdawalla]

A14. I'd root for a Uranus mission over a Neptune mission because I love an underdog and while I appreciate how amazing Triton is, Uranus has a whole family of basically unexplored moons. https://t.co/Mb05cURrCm

My pitch for a #Uranus/#Neptune exploration tagline: “Let’s visit the exoplanet next door.” #DPS18
