#hirise — Public Fediverse posts

[Focus sur #HiRISE] Installé depuis près de deux ans sur le Very Large Telescope (#VLT) de l' @esoastronomy (European Southern Observatory), l'instrument HiRISE vient de caractériser, avec une précision inégalée, la jeune #exoplanète AF Lep b. La mesure directe de la lumière émise a permis de déterminer la composition de son #atmosphere ainsi que la vitesse à laquelle elle décrit son orbite autour de son étoile hôte. Il est ainsi apparu que cette exoplanète était similaire à #Jupiter dans notre Système Solaire.

AF Lep b n’est que la première cible du relevé HiRISE commencé en 2023. D’ici quelques années, toutes les planètes géantes connues en imagerie auront été observées avec HiRISE, ce qui permettra de tester de manière statistique les liens entre composition, vitesse de rotation et mode de formation.

KI enthüllt: Meteoroiden-Einschläge lassen den Mars beben

Meteoroiden-Einschläge verursachen seismische Wellen, die den Mars viel stärker und tiefer beben lassen als vorher angenommen: Dies zeigt eine Untersuchung mit Hilfe von KI, die von einem internationalen Forschungsteam unter Leitung der Uni Bern durchgeführt wurde. ..

Finished my #Mars piece! RIPPLES OF BARSOOM, a close-up of two ancient #Martian tributaries and the main river channel of Nirgal Vallis, as captured by @uahirise . 16x12”, ink on cotton

It’s hard to capture what I’m doing with this latest #Mars piece , but I think at last the sand and rock of converging #Martian #dunes are coming into focus, as captured by HiRISE.

This latest #Mars piece is a lot of squiggly sepia details. The sand and rock textures are a blast to try my hand at representing #Martian #dunes as captured by UAHiRISE. (And you’ll be shocked at what I plan to layer over this! 😉)

#Ingenuity would be easy to spot in an image if it occupied a few visible pixels, since the line-of-sight to the #MarsHelicopter passes right above the Mount Washburn group of hills, where #Perseverance had been 102 sols ago.

Maps were made with #QGIS using #NASA's #MMGIS data and #USGS, #HiRISE DTMs and imagery

"HIGHLIGHTS:
• [They] mapped channels and fossae within the volcanic plains east of Olympus Mons.
• Late Amazonian channels east of Olympus Mons formed by eruptions of lava or water.
• Fossae morphologies correspond to episodes of magmatic dike and sill emplacement.
• Loading of Olympus Mons may control magmatic ascent processes and eruption types..."
