So much for military intelligence.

It's a real game changer when any random zhlub can have up to date satellite photos of anywhere.

Most of the time they are out at sea, and won't come back to base if the situation gets tense. Not the same role as submarines during WWII.

Can you spot the asteroids? Three of them:

I see two. One is in the lower left quadrant moving from left to right. a second one is in the lower right quadrant at about the level and moving from 10 o'clock to 4 O'clock.
There also seems to be a movement near the second-largest star near the top and slightly to right of center in the image. Like something appears and disappears.

This is exactly what I expected a proto-planet to look like at the point in between agglomeration and the point where gravity starts to crush the cluster of boulders into a spherical shape. Very cool.
Such potential!

Not really news (2010), but interesting factoid:
Big Mystery: Jupiter Loses a Stripe

Lost: A giant belt of brown clouds big enough to swallow Earth twenty times over. If found, please return to Jupiter.

May 20, 2010: In a development that has transformed the appearance of the solar system's largest planet, one of Jupiter's two main cloud belts has completely disappeared.

"This is a big event," says planetary scientist Glenn Orton of NASA's Jet Propulsion Lab. "We're monitoring the situation closely and do not yet fully understand what's going on."

Image
These side by side images of Jupiter taken by Australian astrophotographer Anthony Wesley show the SEB in August 2009, but not in May 2010.
Known as the South Equatorial Belt (SEB), the brown cloudy band is twice as wide as Earth and more than twenty times as long. The loss of such an enormous "stripe" can be seen with ease halfway across the solar system.

"In any size telescope, or even in large binoculars, Jupiter's signature appearance has always included two broad equatorial belts," says amateur astronomer Anthony Wesley of Australia. "I remember as a child seeing them through my small backyard refractor and it was unmistakable. Anyone who turns their telescope on Jupiter at the moment, however, will see a planet with only one belt--a very strange sight."

Wesley is a veteran observer of Jupiter, famous for his discovery of a comet hitting the planet in 2009. Like many other astronomers, he noticed the belt fading late last year, "but I certainly didn't expect to see it completely disappear," he says. "Jupiter continues to surprise."

Nasa to make major announcement of ‘exciting news’ about the moon

Nasa will hold a major event to announce an “exciting new discovery” about the Moon, it has said.

The space agency did not reveal details about the discovery, but said that it “contributes to Nasa’s efforts to learn about the Moon in support of deep space exploration”.

It also said that the discovery had come from the Stratospheric Observatory for Infrared Astronomy, or Sofia.

Sofia is a modified Boeing 747 that flies higher than much of the atmosphere, allowing its built-in, 9-foot telescope to get a clear view of our solar system and the broader universe. The plane is able to get up above 99 per cent of the atmosphere’s water vapour, which normally obscures our view of space.

The telescope instruments at the centre of the flying observatory gather infrared light, meaning it can “pick up phenomenon impossible to see with visible light”, Nasa noted in its announcement.
...
Nasa’s notice of the event made heavy reference to the Artemis programme, which hopes to send the first woman and next man to the Moon in 2024, with the hope of using it as a base to launch missions to Mars from the 2030s. They will be the first people to set foot on the Moon since 1972.
...
The event will take place at noon eastern time, or 5pm in the UK, on Monday, 26 October, Nasa said. Audio will be streamed live on its website.

They found Jimmy Hoffa. And Judge Crater.

Reflections of the Ghost Nebula

Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus. Far from your own neighborhood on planet Earth, these ghostly apparitions lurk along the plane of the Milky Way at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over two light-years across and brighter than the other spooky chimeras, VdB 141 or Sh2-136 is also known as the Ghost Nebula, seen at toward the bottom of the featured image. Within the reflection nebula are the telltale signs of dense cores collapsing in the early stages of star formation.
