JWST captured the clearest view of #Neptune’s rings and 7 of its 14 known #moons. #Triton, Neptune’s largest #moon, appears brighter than the planet in this Webb view.

New instruments for Galileo’s tomorrow
Galileo Second Generation is on the way with new and enhanced navigation satellites that will offer novel signals, services and even more precise positioning. But all the work being done to make it happen hinges on this single item at ESA’s Navigation Laboratory at ESTEC. The G2 test user receiver is designed to quantify the improvements the Second Generation will bring compared to current satellite navigation systems and will be used to verify the performance of early receivers processing the first G2 signals in space.

For millennia, musicians have looked to the #heavens for #inspiration. #Now a new collaboration is enabling actual data from NASA telescopes to be used as the basis for #original #music that can be played by humans.
Since 2020, the "sonification" project at NASA's Chandra X-ray Center has translated the digital data taken by telescopes into notes and sounds. This process allows the listener to experience the data through the sense of hearing instead of seeing it as images, a more common way to present astronomical data.
A new phase of the sonification project takes the data into different territory. Working with composer Sophie Kastner, the team has developed versions of the data that can be played by musicians.
"It's like a writing a fictional story that is largely based on real facts," said Kastner. "We are taking the data from space that has been translated into sound and putting a new and human twist on it."
This pilot program focuses on data from a small region at the center of our Milky Way galaxy where a supermassive black hole resides. NASA's Chandra X-ray Observatory, Hubble Space Telescope, and retired Spitzer Space Telescope have all studied this area, which spans about 400 light-years across.
NASA's Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

"Where Parallel Lines Converge" is a #sonic rendering of a composite image of the #GalacticCenter, or the center of our #MilkyWay #galaxy, with data from NASA’s #Chandra, #Hubble and #Spitzer #space #telescopes. The song is a tryptic, highlighting three astronomical objects or moments in the image: the X-ray binary, the arched filaments, and the #supermassive #blackhole, #SagittariusA*.
The piece was conceived using the same principles as the original NASA Chandra data sonifications, converting data to sound by matching different parameters of the image with musical parameters. Composed by Sophie Kastner, this was recorded by #Montreal based #Ensemble Eclat conducted by Charles-Eric LaFontaine on July 19, 2023 at McGill University.

découverte rarissime d’un système de six planètes en résonance
Il s’agit a priori de mini-neptunes chaudes, dans une configuration stable depuis des milliards d’années. Un cas d’école très intéressant pour étudier la formation des planètes en général.
C’est une sorte de mélodie céleste qui pourrait bien inspirer des artistes contemporains. La manière dont les planètes orbitent autour de leur étoile suit parfois des règles dynamiques étonnantes qu’on appelle «résonances». Les interactions gravitationnelles sont alors telles que le système se retrouve «bloqué». Le temps qu’une planète fasse un tour autour de son étoile, une autre fait précisément deux tours. Ou trois. Ou quatre. On parle alors de résonance 1:2, 1:3, ou 1:4. Si une planète fait deux tours pendant qu’une autre en fait trois, alors on parle de résonance 2:3. Etc.
