Day 062, orbit 0963 — Did you know we get 16 sunrises and sunsets every day as we orbit Earth? They come and go quickly, but the colours are so intense! This dramatic, billowing cloud, captured at sunset, stood out with its incredible shades of orange. Nature is definitely an artist. 📷 NASA/ESA – S. Adenot

ohhhh, this is good!

Using the 3.9m AAT, Sarah Caddy and Lee Spitler (from our school!) were able to track Orion on its return trajectory ...

All planetary nebulae are blue and located in very star-rich fields. Upper left nebula shows maybe spiral-like structure. Upper middle nebula is circular with a donut-like shape. Upper right is bipolar with a distinct eye-shape in the middle. Lower left is bright, small and circular with a distinct outer wall and a relative bright central star. Lower middle is very faint, large and circular. Lower right is elliptical with two shells.

A bit of a different take on the amazing Artemis II launch footage.

Here I stitched clips from the four Solar Array Wing Cameras to make this panoramic video.

This is during the later part of the Core Stage burn until MECO and stage separation, sped up to 10x. 🔭🧪 #Artemis

The Sun eclipsed by the Moon, as seen from behind the Moon by the Artemis mission. The glow of the Sun's corona extends beyond the Moon's dark disc.

The Sun eclipsed by Pluto. Pluto's dark disc is rimmed by blue light from its atmosphere backlit by the Sun.

Two of my favorite deep space eclipses, Artemis' Moon and New Horizons' Pluto.

The moon in earthshine, the solar corona, and the planet Venus towards the top from the Clementine spacecraft in 1994.

This Artemis II eclipse is giving me Clementine 1994 vibes with Venus in the background.

On the left is my processed version of the Artemis II photo of the corona emerging from behind the Moon. On the right is the corona as recorded at about that time by SOHO, a Solar observation satellite which monitors the Sun's activity.

Here's the corona at about that time as seen by the SOHO Solar observation satellite, compared with the corona photographed during the Artemis II Lunar flyby. The other side of the corona will be seen in the sunset photos to be released later.

The Moon! The Sun's corona! A crewed spacecraft! Oh my!

Astronomical space art ideally shows something of what is known about the subject as well as what it is about the subject one finds visually appealing. This is a scan of an illustration in the classic book 'The Conquest of Space' by Willy Ley and Chesley Bonestell. Earth is covering the Sun, with Bonestell's very narrow version of the Zodiacal Light extending from behind Earth on both sides. The moonlit Earth shows Africa and the reflection of the Moon on the oceans. A suggestion of cloud detail shows a latitudinal detail bias that was common in his Earth portrayals. In the orientation of the visual elements this painting, done a lifetime ago, carried forward a vision that has just been seen by human eyes and photographed with state of the art equipment. #Sciart

Space art in its roots has been an effort to anticipate sights that future space travelers may one day see. In the late 1940s Chesley Bonestell painted a moonlit Earth that appeared in 'The Conquest of Space'. This modest work shows a view broadly similar to that revealed in the new Artemis photo.

This photograph of the night side of Earth was obtained yesterday after the completion of the trans Lunar engine burn. The original image has been rotated to have North near the top, and the overall tonal values have been adjusted to in my judgement better represent the brightness range between the Moonlit Earth and the bright limb. I have manually removed a couple interior lights reflections from the image. Venus is at the upper left, and the dim fuzzy conical Zodiacal Light looms from behind Earth. The hidden Sun is behind the upper left portion of Earth. Stars are recorded, a rarity in such photography. Aurorae are visible as light green outlines standing apart from the polar regions. Across the entire night side a detached dim olive green 'Airglow' layer outlines the edge, or 'limb' of Earth. City lights are clustered near the coastal regions of the land masses.

The Artemis II crew are well equipped for photography and are paying attention to the opportunities. On the outbound leg of their journey to the Moon this photo showing global scale dim light phenomena was obtained. I have removed the interior cabin lights reflections and adjusted the brightness.

The exhaust plume left behind by the SLS (Space Launch System) rocket that launched Artemis II, NASA’s first crewed mission to the Moon since December 1972, dissipates in the Earth's atmosphere in this photograph from the International Space Station. The orbital outpost was soaring 263 miles above the Atlantic Ocean northwest of Puerto Rico at the time of this photograph. Credit: NASA/Chris Williams

Astronaut Chris Williams managed to capture this cool image of the Artemis II exhaust plume from the ISS.

A rocket plume extends into the sky, topped by a bright light that is the SLS's core stage and solid rocket boosters firing. Light from the launch complex illuminates the base of the plume. The Moon is in the centre of the image.
