The Egg Nebula offers astronomers a rare opportunity to study the death of stars ☠️⭐ it is a pre-planetary nebula, meaning that it is in the fleeting stage that occurs before a planetary nebula. The central cloud of dust is surrounded by concentric rings, which were created by a sequence of outbursts from the dying star. The starlight reflected by these layers of gas reveals important details about the central star, which is impossible to view directly in its dusty shell.

Across a dying star 💀⭐ The Cat’s Eye Nebula is a planetary nebula. This type of object appeared round (planet-like!) in early telescopes, but the NASA/ESA Hubble Space Telescope has revealed a complex morphology – this is especially true of the Cat’s Eye Nebula! In this new image, Hubble captures the core of the billowing gas, its tapestry of concentric shells, and jets of high-speed gas and dense knots sculpted by shock interactions.1/2

The Helix Nebula seen across multiple wavelengths, from visible light through infrared to ultraviolet, each revealing different layers of gas and dust cast off by a dying star roughly 650 light-years away.

Take a journey through space to the remnants of a dying star 🚀 The Cat’s Eye Nebula is an example of a planetary nebula. Named because of their round shape when viewed through early telescopes, they are actually expanding gas thrown off by stars reaching their end. It was the Cat’s Eye Nebula itself where this fact was first discovered in 1864! 1/2

What does a supernova look like? This visualization simulates the first 150 milliseconds of a supernova. As the star collapses in on itself, hot gas emits from its core in uneven shock waves. Researchers use computer simulations like this to more accurately understand the events of a dying star.

This is the protostar HOPS 153, which lies in the nearby Orion Nebula 🏹✨ It is still cocooned in a cloud of cold gas – but as it gathers gas from its nebula, it will grow into a fully-fledged star and dramatically shape its surroundings! 1/2

Astronomers in the year 1054 watched closely as a supernova blazed in the sky. A millennium later, astronomers are keeping a close eye on its remnant, the Crab Nebula 🦀 as it continues to evolve! Hubble first observed the nebula in 1999. Its newest image of the Crab Nebula contains extraordinary details of its filamentary structure and the outward movement of those filaments. 1/2

Labradorite is a stunning mineral known for its iridescence called labradorescence. This optical effect happens when light scatters within layers of the mineral, creating vibrant flashes of blue, green, gold, and even purple—like a peacock’s feathers
