Chandra Release - February 28, 2024

Visual Description: Listen to the Universe: New NASA Sonifications

The first image in this release is the Jellyfish Nebula, also called IC 443. This supernova remnant is shaped like a huge, colorful bubble containing shades of pink, blue, red, and green. Cloud-like structures, both inside the bubble and stretching outside of the bubble to our right and upper left, are filamentary in nature, as if fingers pulled at the edges of a cotton ball. Stars, seen as red dots, are flecked across the entire image.

The second image is Messier 74, a spiral galaxy like our own Milky Way. Seen face-on from our vantage point on Earth, the galaxy's sparkling arms spiral out from a bright white core. The core appears vibrant and alive, and crackles with lightning-like, pale blue light. Glowing, high-energy stars in purple, white, and orange, dot the lengths of the spiraling arms. Webs of murky dust crisscross the space between the curving silver blue arms, also known as dust lanes.

The last image is MSH 15-52, a pulsar wind nebula, which strongly resembles a ghostly purple hand with sparkling fingertips. A pulsar is a highly magnetized collapsed star that rotates and creates jets of matter flowing away from its poles. These jets, along with intense winds of particles, form pulsar wind nebulae. Here, the pulsar wind nebula known as MSH 15-52 resembles a hazy purple cloud set against a black, starry backdrop. 

The shape of this pulsar wind nebula strongly resembles a human hand, including five fingers, a palm and wrist. The bright white spot near the base of the palm is the pulsar itself. 

The three longest fingertips of the hand shape point toward our upper right, or 1:00 on a clock face. There, a small, mottled, orange and yellow cloud appears to sparkle or glow like embers. This orange cloud is part of the remains of the supernova explosion that created the pulsar. The backdrop of stars was captured in infrared light.
