It occurred to me that it's probably 1010, not 1010. When you copy and paste, the superscript is lost.

Duh, I get it. That's like 10 billion, fwiw.

One could also say nothing is moving

It all depends on where put the camera

Before you object, something accelerating is considered moving, if it is changing direction

But then it gets real complicated

Of course. Didn't see that flaw in copy/paste.

The interesting point is that globular clusters are nearly as old as the universe. As we have good theories of stellar evolution that really constrains the cosmological theories, and for some time the problem was that the universe seemed younger than the clusters, which is of course absurd.

But the agreed upon age being now around 13.5 billion years, everything's OK. :)

Seems you swapped "moving" and "accelerating".

Curiosity's latest drill hole in a rock nicknamed "Edinburgh". The hole is about 0.6 inches (1.6 cm) in diameter and 2 inches (5 cm) deep. This photo was taken by night on 22 March 2020, the surface being lightened by LEDs.

Just the hole. I'm not a pervert!

Cute, young tourist photographer visits farm in deep south. Sees two young farmers leaning on their fence.

She stands there fiddling with her camera for time on end.

"Whut's she doin'?" asked farmer 1 of farmer 2.

"Tryin' to focus," replied farmer2.

Farmer 1 was stunned, "Bofus!?"

Bob and Carol and Ted and Alice decide to have group sex. But they want it to be safe sex.

Bob has a rubber, and so does Ted. Two rubbers between them.

Is it possible for Bob to fuck both Carol and Alice AND for Ted to fuck both Carol and Alice with just two rubbers if washing the rubbers is not an option?

I suppose it depends on what you mean by "safe". It's definitely possible to avoid the risk of either of the women getting pregnant. Just a matter of which hole to fuck.

LOOK: Jupiter hi-res photo captured by astronomers using ‘lucky’ technique

https://i.imgur.com/Srhj9vG.jpg

Astronomers have captured one of the highest resolution photos of Jupiter taken from Earth through a technique called “lucky imaging.”

The said technique involves taking “very short” exposure images in infrared of the planet and only using the sharpest ones, when the Earth’s atmosphere is stable. The Gemini Observatory included one of the final images in a statement on its site last Thursday, May 7.

The said picture was made using the Gemini North telescope on Hawaii’s dormant volcano Mauna Kea. It also shows the warm, deep layers of the planet’s atmosphere glowing through its cloud cover, making it appear like a jack-o-lantern.

“The Gemini data were critical because they allowed us to probe deeply into Jupiter’s clouds on a regular schedule,” said Michael Wong of University of California, Berkeley, who led the research team.

He added that the new images rival “the view from space.” The new information also confirmed that the dark spots in Jupiter’s “Great Red Spot” are actually gaps in its cloud cover, and are not caused by cloud color variations.

The images are part of a multi-year program between the observatory and the Hubble Space Telescope to support NASA’s mission to Jupiter called Juno.

Comet Swan
VISIBILITY RIGHT NOW [5/13/2]

C/2020 F8 (SWAN) is above the horizon from Greenwich, United Kingdom [change].
It is visible looking in the South direction at an altitude of 59° above the horizon.
Given its current magnitude, C/2020 F8 (SWAN) is easily visible with the help of a small binocular.

Of course. Especially if one is unconcerned about Carol and Alice continued good health. They won't get preggers, but they may come down with the assorted nasty rashes and occasional outbreaks, etc. provided Bob and Ted aren't the only men Carol or Alice have been fucking in an unprotected fashion. :)

This Citizen Science Gig Pays People to Match Space Photos

Astronomers at the Hubble Image Similarity Project are employing their out-of-work neighbors to help them train a neural net to recognize celestial objects.

https://i.imgur.com/WAR92Q9.jpg

...

Griffith, thus underemployed, perked up right away when her friend Jonathan Obermaier, furloughed from a local brewery, pointed her to a gig on their Hampden neighborhood Facebook page: Astronomers from the Space Telescope Science Institute, just down the road, wanted to pay out-of-work service professionals like her to analyze images from Hubble, Earth’s most iconic telescope. The analyzers would pore over pretty pictures and determine how similar they were to each other for about $1,500, at a rate of around$20 per hour. It’s called the Hubble Image Similarity Project.

...

And they are doing something for her in return—paying her. That’s in contrast with most citizen science projects, which rely on volunteers. It was a very conscious choice for the institute’s astronomers, as cutting paychecks has to be. Joshua Peek and Rick White, the scientists who founded this project, saw so many of their neighbors suddenly without incomes that they wanted to help out. Their own careers and funding are more insulated from the immediate economics of Covid-19, and the astronomers saw an opportunity to create short-term work for others while helping themselves.

Peek—whose family helped organize their block’s pandemic mutual aid group—felt like the aphorism “Think globally; act locally” applied to this situation too. So, for cosmic mutual aid, he says, instead of turning to the whole internet—where most citizen science work is sourced—he turned to his neighbors, “rather than people who are anonymous around the world.”

It's actually called the Seagull Nebula, but so many people say it looks like the Phoenix.

IC 2177 is an H II region of nebulosity centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as "pretty bright, extremely large, irregularly round, very diffuse."

It is 3,600 light years from Earth.

This nebula is captured with narrowband filters to help battle against light pollution in the Detroit area and processed in the Hubble Palette.

For our Japanese residents, but just barely ...
You are watching timeanddate.com's live stream of the annular solar eclipse that is currently in progress in parts if Africa and Asia.

meh, watching an eclipse on youtube is pretty dull, and Graham Jones doesn't help. But I'd love to see it in person, in Asia.

But it's hot outside there so I'd watch it from inside.

On a couch.

p.s. Newser was calling it an annual solar eclipse. Which caused me to blink.
