NGC 7380: The Wizard Nebula

Credit: Nevenka Blagovic Horvat & Miroslav Horvat

www.star.ucl.ac.uk/~apod/apod/a... 🧪🔭

Located only 8,000 light years away, the Wizard nebula, featured here, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star-forming region spans 100 about light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

Dust Storms at Nord Rupes [interpolated] - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2qyHFM1

Andrea Lucks's original version: flic.kr/p/2qtp1Vt

More information about this scene on the ESA Website: www.esa.int/Science_Exploration/Space_Science/Mars_Expres...

I deflickered Andrea's version by transferring only the small scale details to a common background image using a highpass filter.
Since the original animation only contained 7 images, I also used frame interpolation with RIFE 4.4 to create a smooth animation.

Through a gravitational lens effect caused by a massive foreground cluster of galaxies (MACS J0138), multiple images of a perfectly aligned background galaxy (MRG-M0138) are created, including the supernova Encore it hosts. This image was captured by JWST in 2023.

'Satellite Swarm Zoom'

A star trail image made with a time-lapse image sequence photographed by Jonny Kim from ISS. Each image was restored, remastered then retimed using frame interpolation for a short film. These new frames allowed for a simulated long exposure photograph.

A photography of the spiral galaxy NGC 4651. This member of the Virgo Cluster is known as the Umbrella Galaxy due to the umbrella-shaped structure that extends from its disk and that is composed of stellar streams, being the remnants of a much smaller galaxy that has been torn apart by NGC 4651's tidal forces.

The calibration target with, at left, five swatches of spacesuit materials that scientists are studying as they degrade. The first sample at top is polycarbonate for use in a helmet visor; inscribed with the address of the fictional detective Sherlock Holmes, it doubles as a geochache for the public. Other materials in the left row, from top: Vectran; Ortho-Fabric; Teflon; coated Teflon. Right row, from top: aluminum gallium nitride on sapphire; a quartz diffuser; a slice of Martian meteorite; a maze for testing laser intensity; a separate aluminum gallium nitride on sapphire with different properties.

This is an incredibly brilliant idea. We need to set up a UN body in charge of all work and resources for the study of interstellar objects. After all, planetary science is too important to trust to the planetary scientists. But who would direct it?
