Hubble's Messier Marathon 2026

Every year, stargazers convene for the “Messier Marathon” – a challenge to observe as many cosmic objects from the Messier catalog as possible in a single night! French astronomer Charles Messier compiled this catalog in the 1700s, and it features several ideal targets for backyard astronomers. No telescope? No problem! Stargaze from your screen with Hubble.

A dense ball of stars sits at the center of the image, becoming less dense as you move away from the center. They are mostly bright-white stars, but red, yellow, blue, and orange stars are also dotted throughout the cluster.

This beautiful Hubble image of Messier 5 was created with ultraviolet light gathered by Hubble’s Wide Field Camera 3. The data is from an observing program that established an archive of globular clusters in ultraviolet light. This ultraviolet light image compliments the visible and infrared light image below, and highlights the energetic, bright, young, blue stars that dot the cluster.

Hubble & Citizen Science

Hubble's vast and growing archive of observations is a treasure trove for researchers, especially with the support of volunteers who help them comb through and catalog data.

Hundreds of galaxies in a diverse array of shapes and colors are scattered across the dark background of space.

Science Operations

Hubble science operations selects scientific proposals, schedules scientific observations, calibrates and archives mission science data.

Podcast cover illustration for “Universo curioso de la NASA.” The colorful image shows a cosmic landscape with various celestial bodies: a bright yellow Sun, Earth in vibrant blue, green, fuchsia and orange colors; a large red and orange planet representing Mars, a black hole with an accretion disk, and the Moon in purple tones. The title 'Universo curioso' appears in the center with a gradient effect in various colors, and 'DE LA NASA' in smaller dark coral letters. The background is black and dark violet, dotted with small yellow stars and waves that create a vibrant space atmosphere.

A bright binary star surrounded by a colorful nebula on the black background of space. The star in the center is a large white spot surrounded by a circular glow. It has a large, X-shaped set of diffraction spikes around it. The nebula extends far above, below, left and right of the star in long, arcing shapes made of thin, multicolored filaments — mostly red and greenish colors, but lit in a bright cyan near the star where its light illuminates the gas.
