Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.

🤝 Hubble has teamed up with Euclid to image the intricate Cat’s Eye Nebula! 😻

Combining their focused views highlights the nebula’s exquisite structure, while placing it within the broader context.

Mars Perseverance Sol 1787: L/R Mastcam-Z Cameras / enhanced mosaic panorama. A high-resolution image captured by NASA’s Perseverance rover using its Mastcam-Z instrument on Mars. The scene features a barren, sandy terrain with scattered rocks of varying sizes and shapes. The rocks, some jagged and others smooth, are dispersed across the surface, casting subtle shadows in the Martian light. The landscape is typical of the Jezero Crater region, showcasing the arid and rocky environment of the Red Planet."

My goal was to highlight interesting lunar features imaged by LRO that were named for lesser-known scientists. Blagg Crater, named for Mary Adela Blagg, is located in Sinus Medii.

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

An infrared image of the Chamaeleon Infrared Nebula, where a vibrant, wing-shaped cloud of orange and white gas streaks diagonally across a deep blue and black background. At the center of the “wing” is a bright, glowing point of light - a young star- emitting a faint, narrow reddish jet. The surrounding space is filled with wispy blue nebular clouds and scattered, bright stars, including one prominent white star with a pinkish glow on the right side of the frame.

This week’s image is of the Chamaeleon Infrared Nebula! Gemini South’s GMOS captured this stunning image of the nebula, which has allowed astronomers the opportunity to study the circumstellar disk of gas and dust orbiting the central star.
