We just published at @cdsportal.bsky.social a color HiPS for Hubble Space Telescope images, combining 18 individual HiPS.
This data product gives an accurate preview of the HST archive content, spatially and spectrally.

WIP:

Plan oblique HiPS map of Alsace region.

Elevation data from @ignfrance.bsky.social RGE ALTI - Water ways data from @openstreetmap.bsky.social

High-resolution image of the map: filesender.renater.fr?s=download&t...

Final goal is to deliver a similar interactive map for the whole France.

While at CDS, the Aladin project mainly deals with deep sky images, we also map planetary surfaces.

We released the HiPS of China's Tianwen-1 MoRIC images, a true-color map of Mars at 76m resolution.

A nice press release. Check the #AladinLite visualization in the web page, comparing the Einstein cross of the background galaxy as seen by ALMA with the HST near-infrared image of the foreground galaxies.

I arrive here having finished a major, multi-month project: creating a posters in a hachure style reminiscent of centuries past. Have a look: terrainlines.etsy.com.

There's a free ebook, too! somethingaboutmaps.wordpress.com/2024/10/31/a...

If you could share them around, I would be grateful!

A black and white sketch of Mount Hood, seen from a roughly ground level view. It is in a black frame, and on a blue background. Off to the left are a vertically stacked series of smaller images, too small to read. Each is different-looking, but all are black and white miniature versions of posters. The miniature version of the Mount Hood poster is highlighted in white.

Sample images of three monochrome posters each prepared in a line drawing style. One shows Mount Rainier, another Katahdin, and the last one shows Devil's tower. The posters are stacked on top of each other and the Mount Rainier one is partially rolled up.

A detailed zoom in of a hachured representation of the Presidential Range, with peaks labeled.

A vertical-orientation poster titled "The Seven Summits" — it shows black and white sketches of seven different peaks, the highest on each continent. The peak sketches alternate between being positioned on the left and the right side of the poster. Next to each is a label naming the mountain and giving its location. The poster is framed on a blue background.

@vrubinobs.bsky.social First Look images are amazing.
We created a page with image cutouts of all 80,000+ SIMBAD objects in the published fields:

Vous avez probablement vu les premières images spectaculaires du Vera C. Rubin telescope publiées cette semaine. Mais saviez-vous que leur visualiseur Skyviewer repose sur #AladinLite, développé par le @cdsportal.bsky.social ?
Plongez-vous dans ces nouvelles données :
