APOD: Inverted City Beneath Clouds (2020 Jun 24)

Post by APOD Robot » Wed Jun 24, 2020 4:05 am

Image Inverted City Beneath Clouds

Explanation: How could that city be upside-down? The city, Chicago, was actually perfectly right-side up. The long shadows it projected onto nearby Lake Michigan near sunset, however, when seen in reflection, made the buildings appear inverted. This fascinating, puzzling, yet beautiful image was captured by a photographer in 2014 on an airplane on approach to Chicago's O'Hare International Airport. The Sun can be seen both above and below the cloud deck, with the latter reflected in the calm lake. As a bonus, if you look really closely -- and this is quite a challenge -- you can find another airplane in the image, likely also on approach to the same airport.

"I saw a city in the clouds."

Post by neufer » Wed Jun 24, 2020 2:45 pm

-------------------------------------------------------
https://starwars.fandom.com/wiki/Cloud_City

"I saw... I saw a city in the clouds."
―Luke Skywalker[src]

<<Cloud City was a completely man-made Tibanna gas mining colony staff hovering over the gas giant Bespin, occupied by millions of workers, tourists and support staff. Located in Bespin's Life Zone, the station had no need for airlocks or life support systems, with the atmosphere comprised mostly of oxygen and acceptable levels of gravity and temperature. The station was situated 59,000 kilometers above Bespin's core, while its disk was approximately 16.2 kilometers in diameter. 36,000 repulsorlift engines and tractor beam generators kept the giant city floating above the planet. It contained 392 levels, along with platforms and rooms for residents and visitors. The top 50 levels of the city were used as a luxury resort, renowned for its famous casinos such as Yarith Bespin and Pair O'Dice, while the lower levels housed workers and catered for the mining and processing of Tibanna gas.

Popular tourist activities included gambling, hiring a cloud car for sightseeing the city and occasionally touring the local mining operations. The high-end accommodations were exclusive, with luxury resorts often charging as much as 5,000 Imperial credits a night. The Ivax Syndicate also maintained gaming houses on the station. In the months following the Battle of Endor, Cloud City had become the destination to procure rare implants such as brand new oculars and custom-made hands, or entire organ systems for a multitude of alien species. However, following the Empire's occupation of the Anoat sector and subsequently, Cloud City, the distribution of implants was temporarily put on hold.

Generators on the underside of the city emitted tractor beams that converged below the gas mine's reactor bulb, creating a funnel of energy that mined Tibanna gas from Bespin's lower atmosphere, at depths of more than 23,000 kilometers. The gas was forced up into an opening at the bottom of the bulb, where it traveled up the reactor stalk and finally into one of several smaller reactor shafts, where it was then filtered through a processing vane. Each processing vane maintained a carbon-freeze chamber, where Tibanna gas was mixed with carbonite for flash-freeze preservation. One of the chambers was used on the smuggler Han Solo after he was captured by Imperial forces who had recently arrived at the station. Work areas in these lower levels were primarily operated by the sentient Ugnaughts, who performed the monotonous and sometimes dangerous work while bathed in red light, which was the preferred color for the species and also increased their productivity. Many of these tunnels could only be navigated by the Ugnaughts.

Cloud City was run by the Baron Administrator. At some point during the Age of the Empire, Lando Calrissian was given the position. However the day-to-day affairs of the facility were mostly overseen by the cybernetically enhanced human Lobot. Following the departure of Calrissian, a council of business representatives ran the city.

Cloud City was built by the eccentric explorer Lord Ecclessis Figg of Corellia, who offered the freedom of the city to three Ugnaught tribes if they agreed to build the city. With the Ugnaughts having been sold into slavery long ago, the tribes agreed, creating the first iteration of Cloud City.

Sometime after gambling away his starship, the Millennium Falcon, the young smuggler Lando Calrissian gambled big and won control of Cloud City. Sometime during the Age of the Empire, the Devaronian smuggler Gev Hessan did work for Lando to help him build Cloud City.

Shortly after the Battle of Hoth, the fleeing members of the Rebel Alliance (namely Leia Organa, Han Solo and Chewbacca along with their protocol droid C-3PO) landed at Cloud City needing to repair their starship the Millennium Falcon. Initially greeted by Lando Calrissian, the trio ultimately fell victim to Darth Vader's plot to capture Luke Skywalker, using his friends as bait. The Empire coerced Calrissian to surrender the trio to Darth Vader and the Empire, who had arrived shortly before they did. Solo was frozen in carbonite to both reward the bounty hunter Boba Fett for tracking the Rebel trio to Bespin and to test the safety of the facility. Luke Skywalker, sensing the danger his friends were in, arrived at Cloud City in order to mount a rescue only to be engaged in a duel with Vader. By the duel's conclusion, Luke would learn that Darth Vader was his father and would jump down one of the city's reactor shafts in order to avoid joining the dark side of the Force. Meanwhile, Lando Calrissian, upset by the Empire's refusal to abide by the terms of their arrangement—which stipulated that Cloud City was to remain autonomous—warned citizens over an intercom that Imperial forces had invaded the city while his local security forces overwhelmed Imperial forces, allowing Leia Organa, Chewbacca, the two droids and himself to escape the city, picking up an injured Luke Skywalker dangling on a weather scanner vane along the way. Captured and frozen in carbonite, Han Solo was transported in the cargo hold on Boba Fett's starship, the Slave I.

After the capture of the rebels, the Empire took over Cloud City, establishing a skeleton garrison to ensure that the citizens would pay proper taxes and fines to the regime. After the Empire suffered a major defeat at Endor, the Cloud City garrison was pulled to support more strategic targets, and there were celebrations in the streets. In the absence of a baron administrator, a council of business representatives came to run the city.

Before word of the Emperor's death could reach the city, Imperial Governor Ubrik Adelhard established the Iron Blockade over the entirety of the Anoat sector, shutting down travel and communications in and out of Cloud City. The city would also serve as the location of Governor Adelhard's personal chamber located within the prime tower. Ultimately, a militia led by Lobot would succeed in relaying messages to the New Republic, and with the aid of the Uprising, would successfully liberate the city from Imperial control.

In the years leading up to the Battle of Jakku, Lando Calrissian and Lobot led a joint New Republic and Bespin Wing Guard mopping-up operating against Imperial troops who had taken up position in the Casino level's Bolo Tanga room. Calrissian managed to convince a dozen of the Imperials to surrender. However, one of them refused to stand down. The Baron Administrator was forced to shoot him dead with his Vitiator. Calrissian and Lobot then chatted about sending a nuptial gift to Princess Leia Organa's then-newborn son. They settled on sending a Vantillian catamaran.>>

Found the second plane pretty quickly. Very nice image - worthy of desktop background for a day or week to be sure.

Also, it was in the video just a few days ago (2020.06.16) as one of Maria Pflug-Hofmayr's 3 favorite APODs.

----------

The caption says that the other plane is "likely also on approach to the same [O'Hare] airport". Let's see ...
Capture3.JPG
Living near Chicago, I've often seen planes approaching for landing into O'Hare with lots of traffic coming from the east, landing heading west into the airport. Not knowing much about these things, I wondered if the plane in this fantastic image from 2014, which appears to be heading north right over downtown, would actually have been a departure from Chicago's Midway, which is a little southwest of downtown, or perhaps even an approach to Milwaukee's Mitchell airport north of Chicago.

I found this interesting site: webtrak - chicago department of aviation.

I read that traffic flow around these airports changes with the weather, apparently, but today in Chicago is mostly cloudy, somewhat like the conditions in the Astronomy Picture of the Day. At the right is an image from the web tracker from a few minutes ago. It does confirm that right now, at least, much of the traffic into O'Hare heads north right over the city, then immediately turns west to approach and land.

Note: In my image, O'Hare is marked with its call sign: ORD. The planes in dark red are approaching for landing at ORD. Those in dark green are departing. There is one just about to land and one just departed very near the airport. The departures appear to be heading mainly south (though one small plane is shown having departed and headed northwest). Altogether 6 are approaching and they all turn north, then west. Midway airport (shown as "MDW") is lower to the right. Two bright red planes are shown approaching it from the southeast. Plenty of other traffic is shown in white.

Watching this for about a half hour actually was a little jarring to me -- too much traffic!

Are we not also seeing the re-inverted Chicago skyline at the very bottom of the image. I think this is the reflected image being projected on the under side of the thin clouds?

It’s tiny. Look about midway between the yellow reflected sun and the whiter real sun.

Really? I can't believe you can get any sort of definitive identification from that low res silhouette.

Remember, this is what we are looking at:
