Clamshell Nebula Premium Wooden Framed Poster With Museum-Quality Matte Paper

The Clamshell Nebula, designated NGC 6302, is a captivating planetary nebula located in the constellation Scorpius, approximately 3,800 light-years away from Earth. This nebula is often noted for its distinctive, bi-lobed structure, which resembles an open clamshell or butterfly. Such shapes are characteristic of planetary nebulae, formed during the late stages of a star's life when it sheds its outer layers. The central star, a hot white dwarf, plays a critical role in illuminating the surrounding gas and dust, causing it to emit brilliant colors primarily in shades of blue and red. This stunning visual spectacle is not only beautiful but also rich with scientific significance.

The formation of the Clamshell Nebula can be traced back to the final phases of a star similar to our Sun. As the star exhausts its nuclear fuel, it undergoes significant changes, expanding into a red giant before ejecting its outer layers into space. This ejected material becomes the nebula, while the exposed core evolves into a white dwarf. The intense ultraviolet radiation from the white dwarf ionizes the ejected gas, leading to the characteristic glow of the nebula. The intricate structure of NGC 6302, including its prominent jets and varying densities, provides astronomers with valuable information about the dynamics of mass loss in dying stars and the subsequent evolution of nebulae.

Observations of the Clamshell Nebula have revealed complex features that enhance our understanding of stellar processes. For instance, the nebula exhibits high-velocity outflows and asymmetrical structures, suggesting interactions between stellar winds and the surrounding material. The presence of dust lanes adds further complexity, creating regions of varying opacity and enhancing the nebula's visual appeal. As scientists study NGC 6302, they gain insights into the lifecycle of stars and the broader processes that shape the interstellar medium. This makes the Clamshell Nebula a focal point for research in astrophysics, shedding light on the intricate tapestry of the universe's evolution.

Our ready-to-hang premium wooden framed posters showcase meticulous craftsmanship. Milled from responsibly sourced oak, our natural frames have a classic appeal, while our black and white frames, hewn from ash, offer a contemporary touch. The natural pattern of the wood makes every frame distinct, adding to their innate beauty and character. The poster is made on our master's edition, archival museum-quality paper.

Features:

• Our Premium Wooden Framed Posters highlight the natural beauty of real wood grain. We have carefully selected oak and ash for their distinct grain visibility and pronounced pattern, framing your artwork with nature’s finest materials.
• Our frames come in 3 colors: natural wood, black, and white.
• With a 20mm (0.79”) thickness and width, the FSC- certified premium wooden frame has a wider profile compared to our classic frame of 14mm (0.55”). It will be a striking presence on your walls.
• Our Plexiglass material provides a flawless protective layer that allows your creativity to shine while safeguarding against damage. Available in a range of thicknesses, from 1.0-1.2 mm (0.04"-0.05") for small to medium sizes, and a sturdier 2.0-2.5 mm (0.08"-0.1") for larger dimensions, your art is safe in our frames.
• Our matte paper is uncoated and natural white (off-white). The 250 gsm/ 110lb paper is perfect for fine art, designed to last for years without losing its original beauty.
• With alkaline papermaking technology, this poster is acid-free, meaning the pH of the pulp that is used to form the paper is above 7 (neutral). The paper is also buffered with an alkaline reserve, such as calcium carbonate, to neutralize acid compounds absorbed from the atmosphere or formed through natural aging. This ensures that your poster will last many years without any yellowing or discoloration.
• Our poster is free from or low in OBA (optical brightener additives). This ensures that the natural white color of the paper remains consistent under different lighting conditions. In contrast, the color of papers that contain optical brighteners can shift depending on the light source. Additionally, the color of OBA-free paper remains more consistent over time, so you can enjoy the poster for years without any shifts.
• The poster is ready-to-hang as the poster is delivered within the frame. It is ready to be hung directly on the wall.
• We use FSC-certified paper and frame or equivalent certifications depending on regional availability. It’s better for the people and the planet.
• Each poster and frame is shipped in robust packaging, ensuring it arrives in pristine condition.
• Paper sizes may vary slightly by region. For the US and Canada, the measurement is in inches, while for the rest of the world, it is in centimeters.
• For indoor use.
• We print and ship on demand with no minimum orders required.
