The near-perfect symmetry on display here reveals the incredible complexity of galaxy NGC2985. Multiple spiral arms widen as they whirl outward from the galaxy’s bright core, slowly fading until they disappear into the emptiness of space: …

25 years ago this week, fragments of the broken-up Comet Shoemaker-Levy 9 slammed into . Hubble watched the strikes, revealing giant plumes and dark impact scars as they appeared on the battered planet: go.nasa.gov/2JC3ZRp

A new measurement of how fast the universe is expanding has been made! The revised measurement falls in the center of a hotly debated question in astrophysics that may lead to a new interpretation of the universe's fundamental properties: …

We are going forward to the Moon by 2024, but did you know that back in 2005, Dr. Jim Garvin and his team of scientists pointed the Hubble Space Telescope at our nearest celestial neighbor for a very important reason?

NGC1156 is a dwarf irregular galaxy, meaning it lacks a clear spiral or rounded shape. Some pockets of gas rotate in the opposite direction to the rest of the galaxy, suggesting there has been an encounter with another galaxy in it's past: …

As if black holes weren't mysterious enough, astronomers using Hubble have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of spiral galaxy NGC 3147, located 130 million light-years away: …

In this , the light from distant galaxies is being bent & stretched by gravity into weird arcs and shapes, including one that looks like an invading space alien. Check out Hubble pictures of this "gravitational lensing" phenomenon at: …

This Hubble image shows bright, colorful pockets of star formation blooming like roses in a spiral galaxy named NGC 972. The orange-pink glow is created as hydrogen gas reacts to the intense light streaming outwards from nearby newborn star…

Hubble captured this view of Mars between April 27 and May 6, 1999, when the Red Planet was about 54 million miles from Earth. Surface features as small as 12 miles across are visible, including craters, volcanoes, and a storm churning nea…

Astronomers enlisted the combined multi-wavelength capabilities of Hubble and NASAspitzer to assemble for the first time a "fingerprint" of the chemical composition of GJ 3470 b's atmosphere, which turns out to be mostly hydrogen and helium: …

Because of Eta Carinae's violent history, astronomers have kept watch over its activities. Although Hubble has monitored the volatile superstar for 25 years, it still is uncovering new revelations: go.nasa.gov/322Oj0B

Messier 98 is estimated to contain about a trillion stars, and is full of cosmic dust and hydrogen gas. The galaxy shows the characteristic signs of stars springing to life throughout its bright center and whirling arms: …

to French astronomer Charles Messier, born in 1730, who cataloged night-sky objects that can be observed with backyard telescopes, including this , M64 (the Black Eye Galaxy): go.nasa.gov/31Nt178

Scientists using Hubble have confirmed the presence of electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the interstellar medium – the gas and dust that fills interstellar space: …

It's ! 📸 In this close-up scene featuring John Grunsfeld (SciAstro) performing a spacewalk to work on Hubble, the reflection in his helmet visor shows Andrew Feustel (Astro_Feustel) taking the photo perched on the end of the robotic…

IC 10 is a remarkable object. It is the closest-known starburst galaxy, meaning that it is undergoing a furious bout of star formation! ✨ go.nasa.gov/31MSZYr

in 1997 Hubble released this image of a 250-mile-high plume (at left) spouting from Jupiter's volcanic moon Io. Erupting from Io's Pele volcano, the gas & dust must've been blasted at over 2,000 miles per hour to form a plume that big…

RT NASAhistory: Today in 1995, these high-resolution images of Neptune taken by NASAHubble were released. Though we can't see Neptune with the naked eye, we can view the space-based telescope unaided. Hubble will be visible tomorrow morning at 5:02 AM ED…

When massive stars die at the end of their short lives, they light up the cosmos with bursts of light and material known as supernovae. The subject of this image, a spiral galaxy named NGC 4051 has hosted multiple supernovae in past years: …
