Here’s an annotated version of our comet image.

We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

Les caméra du satellite martien Mars Reconnaissance Orbiter ne servent pas qu'à imager la surface de la Planète Rouge, il permettent aussi de faire... de l'astrophotographie, comme cette somptueuse image de Jupiter prise depuis l'orbite martienne.

Pluto in the middle and 4 copies of moon Charon around it. The smaller moons Nix and Hydra are present with 4 copies each on the left side of the image.

#Pluto system with #Hubble from July 2019. Four images were taken. The movement of the moons #Nix and #Hydra being anti-clockwise.

On July 3rd, astronaut Nichole Ayers photographed a gigantic jet from the ISS. These rare upward directed electrical discharges extend ~90-100 km high into the mesosphere. The jet originated from a thunderstorm over Northern Mexico, with city lights from South Texas and the green airglow layer visible along Earth’s limb. I processed this image from the RAW file, adjusting the color profile, white balance and contrast and applied Lightroom's machine learning denoise with low strength. The RAW was provided to me by Frankie Lucena, his analysis of the event, correlating it to measurements from the Geostationary Lightning mapper and ELF-VLF radio signals can be found here: spaceweathergallery2.com/indiv_upload.php?upload_id=224355 Original image listing in the NASA archive: eol.jsc.nasa.gov/SearchPhotos/photo.pl?mission=ISS073&amp...

Saturn passing behind the Moon on the morning of Sept 17, 2024. Also resolved are Saturn's moons Titan (left) and Tethys (right). Imaged with 14" LX200 Schmidt-Cassegrain telescope at f/10 from La Crescenta, California. Note that Saturn detail was enhanced by blending a sharpened stack of images captured immediately prior to the occultation.

This is a dust devil... on Mars.

Intricate smooth rings of Saturn, broken by a wavy dark gap, with a tough, oblong little moon inside the edge of the gap.

Making waves:
You can see Saturn’s little moon Daphnis (8 km) and the waves it’s raised with its gravitational pull, along this gap in the rings of Saturn. (NASA/Cassini)

The eye of Hurricane Melissa.

Image taken today by Sentinel-2.

This is footage taken earlier today of the eye of Hurricane Melissa.

The entire view is remarkable, of the core of one of the strongest Atlantic basic hurricanes in recorded history, and a catastrophic hit to Jamaica and the central Caribbean.

In the foreground, the limb of the Moon against blackest space. In the centre background, most of Saturn and half of its ring system is seen.

Saturn peeking out from behind the Moon.

Photographed by Paul Stewart (astrostew.bsky.social) on 14 May 2014, this scene is a composite of three images given the vastly different brightness levels of the Moon and Saturn when viewed from Earth.

At the time, Saturn was 1.625 billion km from Earth.

Le saviez-vous ?

C'est parce que la Lune tourne sur elle-même que l'on voit toujours la même face depuis la Terre (appelée "face visible").

Si elle ne tournait pas sur elle-même (ci-dessous), on verrait progressivement toute sa surface au cours d'un mois lunaire.

The photo shows the Moon in waxing gibbous phase with an illumination of 91%, captured at Arches National Park in Utah, on 28 October 2020. The Moon creates the effect of a giant eye as it passes behind a rock arch.

Stunning image captured, at Arches National Park in Utah, by photographer Zach Cooley on 28 October 2020 when the Moon was in waxing gibbous phase with an illumination of 91%.

Precisely, 91% was the percentage illuminated by the Sun.
