That’s no moon, it’s a space station spherical potato

This seems to be the source:

…nasa.gov/…/global-image-of-io-true-color/

Thanks! My opinion is that images from NASA, ESA etc should always link to the source. They always include interesting information about what is in the image. It is also nice if I don’t need to search the database for ages.

Yeah… I kind of wish it was a request of the channel. I’ve found a few of the sources now and it’s mostly on this channel people seem to post other people’s images with no references

I guess OP found this in yesterday’s ‘Astronomy Picture of the Day’, which includes the link you sent. Would’ve cost a second to include it in the post.

I wonder what we can do to help motivate including links to sources

I messaged the moderator asking if we could update the channel description but haven’t heard back

MetalSlugX, w Io in True Color

Not true color. This is an “enhanced” photo.

Mac,

Indeed.

This color mosaic uses the near-infrared, green and violet filters (slightly more than the visible range) of the spacecraft’s camera and approximates what the human eye would see.

bear,

It world also appear much darker.

I didn’t think about that. It almost looks metallic, or like the shading you see with 3d modelling software

sukhmel,

The source claims that enhanced is this one: …nasa.gov/…/global-image-of-io-false-color/

What is Io’s footprint?

What spectrum is this?

The eye glows in infrared!!

Thorry, w Jupiter from the Webb Space Telescope

It’s still stunning to me how small the great red spot has become. If it gets any smaller it’s hardly a feature worth talking about. I remember back in the 80’s looking through my telescope at Jupiter and clearly seeing the spot. I know it’s entirely possible, but to see a large thing like that visibly change over my lifetime still somehow feels wrong.

doc, w Jupiter from the Webb Space Telescope

Would love to have one without the labels. Perfect wallpaper material. Is the source somewhere in nasa.gov?

200ok, w Plato and the Lunar Alps

About one-third the length of the range from the southeast is Mons Blanc, a peak rising to a height of 3.6 km. This compares to a typical height of peaks in this range of 1.8 to 2.4 km.

~ en.wikipedia.org/wiki/Montes_Alpes

Those are a lot taller than I imagined! The actual Alps in Europe are just taller than 4km so I can understand the reference.

Explanation: The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The featured deep image is a digital combination of images taken in different colors over 58 hours with a telescope from Lijiang, China. Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of the Hunting Dogs (Canes Venatici). M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies. Astronomers speculate that M51’s spiral structure is primarily due to its gravitational interaction with the smaller galaxy just above it.

Robomekk, w [Stephen Clark] NASA launches new mission to get the most out of the James Webb Space Telescope

Quick summary seems to be that they’re using it to monitor the stars that Webb is seeing planets pass in front of. To better model that stars behaviour with prolonged observation. To better understand whether signals that look like water and methane are really from the passing planet, or just from changes in the star’s activity over time.

The player must learn speed control and obstacle jumping to succeed in run 3, as even the slightest error can cause accidents and failure to complete stages.

Geometry Dash SubZero throws you right into the action with levels that don't mess around and graphics that are as cold as ice. You need to have great timing and quick reflexes—one mistake and you have to start over.
