This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere. The new image was taken in visible light as part of the Outer Planets Atmospheres Legacy program, or OPAL. The program provides yearly Hubble global views of the outer planets to look for changes in their storms, winds and clouds. Hubble's Wide Field Camera 3 observed Jupiter when the planet was 400 million miles from Earth, when Jupiter was near "opposition" or almost directly opposite the Sun in the sky....
This animation (below) of a rotating Jupiter was assembled from a Hubble Space Telescope photographic mosaic of almost the entire planet. The resulting flat map was computer-projected onto a sphere to create a rotating globe (excluding the polar regions above 80 degrees latitude). Jupiter completes one rotation every 9.8 hours. The giant planet's trademark Great Red Spot is the orange-colored oval that is as big as Earth. Distinct parallel bands of roiling clouds dominate our view above Jupiter's deep hydrogen/helium atmosphere. The colorful cloud bands are confined by jet streams blowing in opposite directions at different latitudes. A characteristic string of white oval-shaped anticyclones appears along one latitude band in the planet’s southern hemisphere.

Thomas Romer of the excellent Chop Shop Studio in collaboration with the nonprofit Planetary Society designed these delightful solar system toy blocks to teach kids (and adults) about the wonders of outer space! He's launched a Kickstarter to fund the manufacturing of the wood blocks with debossed typography. They're $75/set. Thomas says:
We worked on the project for over a year and while I did the graphics, etc — they made sure all the data was accurate and totally up to date. It is a set of 20 blocks featuring the most interesting worlds of the Solar System. Notice I didn’t say “planets”. One of my main objectives is to show children (and adults) that planet or not doesn’t matter. There are worlds like Io and Europa that most have never heard of. Two moons are bigger than Mercury, never mind Pluto (also included).
Then each side is loaded with data like size, distance, interior, name, appearance and the missions we have sent to explore them.
When they are shipped to our (Kickstarter) backers they will be sold in the Planetary Society store and profits will be sent to support their overall mission.

I'm fascinated by painting of an extrasolar planet, credited to "Beau.TheConsortium" and apparently first posted to this SF Wiki. They're called "eyeball planets" -- similar to Earth, but tidally locked with their star, creating a vast polar ice cap on the dark side, a scorching desert facing the sun, and a band around the center where water melts from one side to the other and life happens. The extremes involved have made them a hot topic among those searching for life.

The sweet spot—let’s call it the “ring of life”—is at the terminator, the boundary between night and day. The ring of life is bounded by deserts on one side and ice on the other. There is a constant flow of water from the night side to the day side—a series of rivers, all flowing in the same direction. The Sun is fixed in the sky right at the horizon, and the area is in permanent light. Conditions are pretty much the same all the way across the ring of life. One can imagine vegetation following the rivers onto the day side until they dry up, with different ecosystems interspersed along the way. There could be mountains at the edge of the ice sheets, since the ice-covered continents would be heavily weighed down
Mars enthusiast Jan Fröjdman painstakingly composited a fictive flight above real Mars, based on actual images of the surface of Mars. The goal was to make some of Mars' fascinating topography feel more real. All that work paid off. Read the rest

iBleeedorange posted this pretty GIF that shows the 5-fold pattern traced out by an imaginary line between the Earth and Venus.
Sunsunsun made an audio representation of the orbital relationship between Earth and Venus:
The left side is Venus and the right side is Earth. It takes about 1:36 to synch up, but it almost synchs up (the planets would be directly opposite each other) around 46 seconds in. Each 8 bars represents an orbit around the sun. Do not listen to this without headphones, it makes no sense without being able to separate them.
Make you own "dances of the planets" here.

Jupiter is more beautiful than ever in this footage from NASA, as used by Adrienne Lafrance to illustrate her splendid article about the gas giant.
rom far away, the planet looks vaguely beige. But its clouds are a kaleidoscope of warm colors—alternately red, orange, pink, and tan, with some blue. That may be the effect of sunlight breaking down chemicals like ammonia, but scientists aren’t sure. “We still don't know what makes the clouds the colors they are,” Simon said. “Another thing we don’t know is: Why the storms last so long.”
In the future, the people who live around Jupiter are going to be really smug, aren't they?
Its reputation was once not so grand, Lafrance adds in a follow-up that astronomers used to find the painterly, swirling surface quite unpleasant.
It was generally hoped that, in couse [sic] of time, this much respected orb would see the error of his ways, and cease to assume the appearance of an inebriated planet.
Sad to relate, however, he has gone from bad to worse, and is just now showing, side by side with the red spot complained of, a number of white ones, which give his countenance an appearance truly sad to behold. No wonder that quiet, staid astronomers, who, from joking, stand aghast at such an exhibition.

A central asian nation may have no easy path to the sea, but its future among the stars is assured—at least in its dreams.
Tajikistan's state new agency reports [translate] that the country has named "one of the small planets of the solar system" for itself, but did not specify exactly which one, or how it will come to be "between Mars and Jupiter" and have an orbital revolution equivalent to the 5-year term of the national parliamentary assembly.
According to the press release, the name was affirmed by the International Astrophysicists Union.
It was emphasized that the planet Tajikistan is located between the planets Mars and Jupiter, its distance from the Earth is 250 million kilometers, and from the Sun is 463 million kilometers. Tajikistan planet revolves around the sun once every five years.
Now the planet Tajikistan is at a very close distance to Earth and Tajik scholars engaged in the study of its physical and chemical properties, as well as the processes taking place on this planet.
President Emomali Rahmon expressed appreciation for the contribution of the Tajik scientists in the world of astrophysics, and expressed confidence that such valuable achievements require from our scientists and researchers more effort in the interests of the state and the nation, as well as all mankind.
Eurasianet suspects that "there are some unexplained aspects to the story."

For instance, the International Astrophysicists Union, if it indeed exists, appears to have no online presence. And were it a real organization, it would be rather odd for it to be getting into the business of naming planets, since that might be considered more strictly the domain of astronomers.
Space truth, more awesome than fiction.
NASA’s New Horizons spacecraft is expected to radio home any minute now. We're watching on NASA TV. The moment will end a nearly 22-hour radio blackout as the probe focused on a series of close-up observations of Pluto and its moons.
From SpaceFlight Now:
Engineers expect to lock on to a carrier signal, then start receiving housekeeping data on the status of the New Horizons spacecraft. No science data will come down during Tuesday night’s pass.
“The reason why you’re not seeing more things immediately is because the spacecraft is spending all its time making the observations of the Pluto system,” says Hal Weaver, New Horizons’ project sciences from the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. “That’s what we wanted to do. Of course, you want to optimize the scientific return from the mission.
A signal from New Horizons will be a celebratory moment for the hundreds of engineers and scientists working on the mission. The cessation of communications was part of the plan going into the flyby because New Horizons carries a fixed antenna, meaning mission managers have to choose between contacting Earth and conducting scientific work at Pluto.

“Their non-planetary status is a handicap because these are the worlds that we need to get Earthlings excited about exploring.”
Alex Boese has a great article on About Entertainment on the history of people who claimed ownership of stars, moons, and planets and then sold deeds to plots of land on the heavenly bodies. And they had buyers!
In 2013, Maria Angeles Duran began selling plots of land on eBay. That, in itself, isn't unusual, but the land she was selling was located on the sun. She offered square-meter plots for the price of 1 euro each. By 2015, she had over 600 buyers, but then eBay pulled the plug on her, saying her auctions violated its "intangible goods" policy.
Duran didn't take this lying down. She sued the auction site for violation of contract, arguing that the sun is, indeed, a tangible object, and a Spanish court agreed to hear her case.
