NASA's Tiny Yet Mighty 36-Pixel Camera

NASA's James Webb Space Telescope is wowing astronomers with its high-resolution 122-megapixel primarily infrared photos
May 6, 2024

NASA's latest space explorer, the X-ray Imaging and Spectroscopy Mission (XRISM), is revolutionizing our understanding of the cosmos, one pixel at a time. Unlike the James Webb Space Telescope's megapixel imagery, XRISM operates with a mere 36 pixels. This collaboration between NASA and the Japan Aerospace Exploration Agency (JAXA) is proving that size isn't everything when it comes to capturing the mysteries of space.

Launched into orbit last September, XRISM's Resolve instrument boasts a microscopic 36-pixel image sensor. Despite its diminutive pixel count, Resolve's capabilities are groundbreaking. Each pixel functions as a microcalorimeter spectrometer, meticulously measuring the heat produced by incoming X-rays. This allows scientists to discern the chemical composition of celestial sources with unparalleled precision.

Equipped to detect "soft" X-rays with energies far surpassing visible light, Resolve primarily focuses on exploring the universe's hottest and most massive objects, such as supermassive black holes. Although limited in pixel count, each pixel in Resolve generates an expansive spectrum of visual data, spanning an energy range from 400 to 12,000 electron volts.

One of Resolve's most remarkable features is its ability to perceive the movements of elements within its target areas, effectively offering a three-dimensional perspective. This capability provides scientists with invaluable insights into the dynamics of celestial bodies, including the flow of hot gas in galaxy clusters and the intricate movement of elements in the aftermath of supernova explosions.
