NASA has reprocessed images of Jupiter’s moon Europa that were captured by its Galileo spacecraft back in the 1990s. The reprocessed versions of the images reveal the moon’s surface in stunning detail, highlighting what NASA refers to as ‘chaos terrain’ and a variety of details about the features found on the surface. The new versions of the images are made possible using modern image processing technologies.

The image data was originally captured in the late 1990s, according to NASA, making them more than 20 years old. New image processing techniques have given the space agency the opportunity to revisit this old data and learn more from what it has to offer — namely, to better explore the details of Europa’s surface, or at least how it existed decades ago.

..."modern image processing technologies...."

What would those be exactly?

Take a break from the junk science all around us and look at some real science!

That’s fantastic. Mining and enhancing old data to get more out of it.

They look like snowmobile tracks.

Newer and different colors I presume.

Is that a black obelisk there in a crater in the center right of the picture?

Newer and different colors I presume.

Merging of multiple images taken at slightly different angles and then transforming the resulting blurs. Also, analyzing the angle of lighting and spectrum of the original images can yield additional details.

It is a bit more than just changing the color scheme.

The red color looks like the red algae that I would see in the snowfields of the High Sierra in the summertime. Only way to find out is to take a sample with a spaceprobe.

Better faster computers. Better algorithms

Here’s a shot of the far side of Europa. It is disturbing, to say the least.

Pretty sure it’s paint by numbers.

No. The color scale has not changed. What has changed I’d faster more powerful computers. Also what’s changed are the algorithms that allow for the data to be interpreted

No

But I’m sure Richard Hoagland would agree with you

It is a heavily saturated field of meteorite hits

De involving some info. Reinterpreting other

It’s a dance in contrast

No, it reads “J. Pollock Was Here”.
