A richly detailed infrared image of planetary nebula NGC 6072, taken by the James Webb Space Telescope. Glowing red gas forms an intricate, layered structure with arcs, filaments, and overlapping loops. The central region appears brighter, with complex textures and hints of symmetry distorted by past stellar outflows. The reddish hue indicates cool hydrogen gas, while subtle variations in brightness reveal the nebula’s depth and density.

A star like our Sun died—but it didn’t go quietly. 🌌

A widefield astrophotograph showing the Andromeda Galaxy (M31) on the left and faint blue arcs stretching toward the right. The arcs, part of a structure called SDSO 1, are ghostly and curved, resembling wispy loops or filaments. A red hydrogen trail subtly frames the scene. Countless stars fill the background, creating a rich galactic field.

Discovered in 2022, these faint blue arcs aren’t distant, they’re part of our Milky Way. Called SDSO 1, they mark a new class of fading planetary nebulas.

A small, dark, wedge-shaped cloud stands out against the glowing background of the Eagle Nebula. The nebula is filled with reddish and orange gas, scattered stars, and diffuse light. The dark cloud, known as a Bok globule, appears dense and opaque, obscuring the stars behind it.

A dark shape drifts in a sea of stars.

This tiny wedge of gas and dust, called a Bok globule, floats inside the Eagle Nebula. One day, it may collapse to form a star.

A telescopic image of Saturn with its rings nearly edge-on, creating a thin horizontal line across the planet. Saturn's banded atmosphere is clearly visible. At the upper left, Saturn’s largest moon Titan appears as a small pale dot, while a round, dark shadow from Titan is cast onto the gas giant’s cloud tops, just above the rings. The contrast between the planet, rings, moon, and shadow makes the scene striking and dynamic.

Every 15 years, Saturn’s rings appear edge-on from Earth — a rare chance to see its moons transit the planet.

In this view from July 18, Titan crosses Saturn’s face, casting a dark shadow on its cloud tops.

A dramatic night sky scene with a bright fireball streaking diagonally across the sky, leaving a glowing trail behind. The meteor’s light reflects slightly on the beach below, where driftwood lies scattered on the sand. Tall trees frame the sides of the image, and stars fill the background above Cape San Blas, Florida.

Ever seen a meteor brighter than the Moon? ☄️

A bright, circular supernova remnant set against a dark background filled with stars. The structure has a glowing, irregular shell with wisps and filaments in shades of red and orange, indicating expanding gas. The remnant is nearly symmetric, suggesting a powerful explosion at its center. Faint background stars from a Hubble image are visible beyond the nebula, adding depth to the cosmic scene.

Can a supernova explode twice? 💥
In SNR 0509-67.5, a white dwarf's surface ignites first, then triggers a second explosion deeper inside.

This remnant, captured by the Very Large Telescope, shows two shells that support the theory.
