In Snow Crash, I wanted Neal Stephenson to have a franchulate called the “International Church of Pancakes” where those seeking refuge could go, catch breakfast and receive some uplifting moral message. But no – just a sword fighting Hiro and skate boarding Y.T. hanging out in the Metaverse. :thumb_up:

"New Horizons" in that dystopia would be passé. :(
Almost all works of fiction fail to give sufficient consideration to the human need for nutrition.
I might consider joining your Church of Pancakes. But for the time being I'm waffling on that decision.

Oh a stack of pancakes; two fried eggs; two slices of bacon; and a hot cup of coffee! :D :wink: 8-) Oh; now I'm hungry!

An ICOP franchise might lead to new horizons within the breakfast community but face far flung difficulties for their legal department. :yes:

I would still entertain investors for my high-flying concept for a down-to-earth restaurant; “Out of this World!” Diners would eat around a huge rotating globe of the Earth while viewing, behind, an awesome planetarium. I think my fav would be in the “Orion” section though the view from “Sagittarius” might be pretty good too. :thumb_up:

I have my architects and engineers working on it full-time. No, I'm afraid my plan wouldn't float which would just ruin the effect. :wink:

New Horizons Indicates Small Objects Are Rare in the Kuiper Belt

New Horizons Indicates Small Objects Are Rare in the Kuiper Belt
Southwest Research Institute | New Horizons | 2019 Feb 28
Using New Horizons data from the Pluto-Charon flyby in 2015, a Southwest Research Institute-led team of scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt. The evidence for the paucity of small Kuiper Belt objects (KBOs) comes from New Horizons imaging that revealed a dearth of small craters on Pluto’s largest satellite, Charon, indicating that impactors from 300 feet to 1 mile (91 meters to 1.6 km) in diameter must also be rare.

The Kuiper Belt is a donut-shaped region of icy bodies beyond the orbit of Neptune. Because small Kuiper Belt objects were some of the “feedstock” from which planets formed, this research provides new insights into how the solar system originated. ...

“These smaller Kuiper Belt objects are much too small to really see with any telescopes at such a great distance,” said SwRI’s Dr. Kelsi Singer ... “New Horizons flying directly through the Kuiper Belt and collecting data there was key to learning about both large and small bodies of the Belt.” ...

So! It may be possible that New Horizons mission may be over for lack of subject matter? :shock:

Ultima Thule in 3D

Ultima Thule in 3D
NASA | JHU APL | SwRI | New Horizons | 2019 Mar 07

New Horizons Team Uses Stereo Imaging to Examine Kuiper Belt Object's Features

Cross your eyes and break out the 3D glasses! NASA’s New Horizons team has created new stereo views of the Kuiper Belt object nicknamed Ultima Thule – the target of the New Horizons spacecraft’s historic New Year’s 2019 flyby, four billion miles from Earth – and the images are as cool and captivating as they are scientifically valuable.

The 3D effects come from pairing or combining images taken at slightly different viewing angles, creating a “binocular” effect, just as the slight separation of our eyes allows us to see three-dimensionally. For the images on this page, the New Horizons team paired sets of processed images taken by the spacecraft’s Long-Range Reconnaissance Imager (LORRI) at 5:01 and 5:26 Universal Time on Jan. 1, from respective distances of 17,400 miles (28,000 kilometers) and 4,100 miles (6,600 kilometers), offering respective original scales of about 430 feet (130 meters) and 110 feet (33 meters) per pixel.

The viewing direction for the earlier sequence was slightly different than the later set, which consists of the highest-resolution images obtained with LORRI. The closer view offers about four times higher resolution per pixel but, because of shorter exposure time, lower image quality. The combination, however, creates a stereo view of the object (officially named 2014 MU69) better than the team could previously create.

3D Glasses, Flicker Animation, Parallel, and Cross-Eyed Views are available.

Thanks by; nice 3-D when you cross your eyes. I like it better than the one that you have to use the 3-D glasses on! 8-) :)

A Prehistoric Puzzle in the Kuiper Belt

NASA’s New Horizons Team Unravels the Many Mysteries of Ultima Thule

The farthest object ever explored is slowly revealing its secrets, as scientists piece together the puzzles of Ultima Thule – the Kuiper Belt object NASA's New Horizons spacecraft flew past on New Year's Day, four billion miles from Earth.

Analyzing the data New Horizons has been sending home since the flyby of Ultima Thule (officially named 2014 MU69), mission scientists are learning more about the development, geology and composition of this ancient relic of solar system formation. The team discussed those findings today at the 50th Lunar and Planetary Science Conference in The Woodlands, Texas.

Ultima Thule is the first unquestionably primordial contact binary ever explored. Approach pictures of Ultima Thule hinted at a strange, snowman-like shape for the binary, but further analysis of images, taken near closest approach – New Horizons came to within just 2,200 miles (3,500 kilometers) – have uncovered just how unusual the KBO's shape really is. At 22 miles (35 kilometers) long, Ultima Thule consists of a large, flat lobe (nicknamed "Ultima") connected to a smaller, rounder lobe (nicknamed "Thule"). ...

Because it is so well preserved, Ultima Thule is offering our clearest look back to the era of planetesimal accretion and the earliest stages of planetary formation. Apparently Ultima Thule's two lobes once orbited each other, like many so-called binary worlds in the Kuiper Belt, until something brought them together in a "gentle" merger. ...

Approach to Ultima Thule

Post by daddyo » Tue Apr 09, 2019 6:38 pm

There's a new movie of the approach/recede from Ultima Thule that has what look like a number of variable stars in the background (I counted 18 so far): http://pluto.jhuapl.edu/images/main-pag ... npage2.mp4

Another link with more information, noting there are synthesized frames in there as well so I imagine there are some artificial effects in the pulsing of the stars, for instance I see a group of 3-4 flashing in sequence near the beginning middle right row, and another up-right from center that flashes 4 times then pauses: http://pluto.jhuapl.edu/Galleries/Featu ... age_id=603

It is unlikely that there are any stars in this sequence that are variable enough to be visible. All of the apparently variable stars here are probably artifacts of the production process.

I’m just not sure how specific stars in this video, a very small percentage of those visible, cyclically pulse in intensity many times each. I don’t see anything unique about them in terms of apparent size/intensity etc. that might help produce this effect from interpolation or other video techniques. I would have to think that they do vary in intensity in some manner, at least.

Note my post was originally to relate observations here (but was moved): https://apod.nasa.gov/apod/ap190328.html
