Green Yellow Honeycombe Array Starbase 1 – Stephans Quintet – Card

£6.00

The cosmos itself is reimagined through a fibrous texture, depicting the intricate beauty of space. It is brought to life with hues of a citrus jade green and rich gold glass-like lens, creating a composition that is visually striking. The mirror array of the James Webb Space Telescope is suggested with muted green outlines and glass-like colours to show the hexagonal segments.

The galaxies, depicted with a fibrous texture, convey a sense of the universe’s complexity and depth. The intricate network of fibres suggest the myriad planes and dimensions that make up the universe. The texture adds an abstract sense of tangibility to the light years of darkness between the stars and hints at the unseen forces and structures that govern the cosmos.

The rich gold and green elements in the artwork bring to it a regal quality, emphasizing the grandeur and majesty of the scene rendered with a tactile richness.

Cosmic Stuff Fine Art Greetings Cards are printed on a lovely heavy weight gloss paper. They are perfect for birthday greetings, sending Thank You notes or with letters tucked inside, graduations, for new home owners and many other occasions. These cards make a thoughtful addition to any of our other products, to include your own special hand written messages. Each has it’s own envelope and they are left blank for your messages.

Narrative behind the art:
Each of the 18 hexagonal-shaped mirror segments is 1.32 meters (4.3 feet) in diameter, flat to flat. (Webb’s secondary mirror is 0.74 meters in diameter.) The primary mirror segments also have an additional actuator at its centre that adjusts its curvature. The telescope’s tertiary mirror remains stationary.

The mirrors are made of beryllium because it is very strong for its weight and is good at holding its shape across a range of temperatures. Beryllium is a good conductor of electricity and heat, and is not magnetic.

Aligning the primary mirror segments as though they are a single large mirror means each mirror is aligned to 1/10,000th the thickness of a human hair. Webb needs to be very cold (“cryogenic”), with its mirrors at around -220 degrees C (-364 degree F).

Once a mirror segment’s final shape is corrected for any imaging effects due to cold temperatures, and polishing is complete, a thin coating of gold is applied. Gold improves the mirror’s reflection of infrared light. The mirrors are put inside a vacuum chamber and a small quantity of gold, about the weight of a golf ball, is vaporized and it deposits on the mirror. A thin layer of amorphous SiO2 (glass) is deposited on top of the gold to protect it from scratches in case of handling or if particles get on the surface and move around (the gold is pure and very soft).

Engineers on Earth made adjustments/corrections to the positioning of the Webb telescope’s primary mirror segments to bring them into alignment – to ensure they would produce sharp, focused images. These corrections were made through a process called wavefront sensing and control, which aligns the mirrors to within tens of nanometres. The work performed on the telescope optics resulted in a NASA tech spinoff for diagnosing eye conditions and accurate mapping of the eye.. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb’s MIRI instrument captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster. MIRI sees a distinct difference in colour between the dust in the galaxies versus the shock waves between the interacting galaxies.

NGC 7320 resides 40 million light-years from Earth, while the other four galaxies (NGC 7317, NGC 7318A, NGC 7318B, and NGC 7319) are about 290 million light-years away.

This proximity provides astronomers a ringside seat for witnessing the merging of and interactions between galaxies that are so crucial to all of galaxy evolution. Rarely do scientists see in so much exquisite detail how interacting galaxies trigger star formation in each other, and how the gas in these galaxies is being disturbed. Stephan’s Quintet is a fantastic “laboratory” for studying these processes fundamental to all galaxies.

Close groups like this may have been more common in the early universe. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust.
