As a cosmic photographer, NASA's Hubble Space Telescope has taken over a million snapshots documenting the universe. These images illustrate, explain, and inspire us with their grandeur. But how are… Continue reading 56-How Hubble Images Are Made

New images of Saturn from NASA’s Hubble Space Telescope herald the start of the planet’s “spoke season” surrounding its equinox, when enigmatic features appear across its rings. The cause of… Continue reading 57-Saturn’s Rings Are Acting Strange

When the Hubble Space Telescope launched, one of its main goals was to learn more about our incredible universe. While we’re used to Hubble images coming from thousands of light-years… Continue reading 58-Planetary Missions: Fossils of our Solar System

Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it… Continue reading 59-Hubble Finds Hungry Black Hole Twisting Captured Star Into Donut Shape

RS Puppis is a glittering star 200 times larger than our Sun and wreathed with dust reflecting starlight. Located about 6,500 light-years away, this star rhythmically brightens and dims over… Continue reading 60-Sonification of RS Puppis

Using data from NASA’s Hubble and Spitzer Space Telescopes, astronomers have found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a… Continue reading 61-Two Exoplanets May Be Water Worlds

The Hubble Space Telescope has taken over 1.5 million observations over the past 32 years. One of them is the breathtaking image of the Carina Nebula. Hubble's view of the… Continue reading 62-Hubble’s Inside The Image: Carina Nebula

Astronomers using NASA’s Hubble Space Telescope have found a jet propelled through space at nearly the speed of light by the titanic collision between two neutron stars, which are the… Continue reading 69-Hubble Reveals Ultra-Relativistic Jet

The DART mission deployed a kinetic impactor to smack the small moon Dimorphos of the asteroid Didymos on the evening of Sept. 26. This was an on-orbit demonstration of asteroid… Continue reading 70-Hubble Views Aftermath of DART Impact

Nature likes spirals — from the whirlpool of a hurricane, to pinwheel-shaped protoplanetary disks around newborn stars, to the vast realms of spiral galaxies across our universe. Now astronomers are… Continue reading 71-Hubble Spots Spiraling Stars

A star’s death throes have so violently disrupted its planetary system that the dead star left behind, called a white dwarf, is siphoning off debris from both the system’s inner… Continue reading 72-Dead Star Caught Ripping Up Planetary System

Our Milky Way galaxy is haunted. The vast gulf of space between the stars is plied by the dead, burned-out and crushed remnants of once glorious stars. These black holes… Continue reading 73-Hubble Measures Potential Isolated Black Hole Roaming Galaxy
