Apocalypse When? Hubble Casts Doubt on Certainty of Galactic Collision

As far back as 1912, astronomers realized that the Andromeda galaxy — then thought to be only a nebula — was headed our way. A century later, astronomers using NASA’s Hubble Space Telescope were able to measure the sideways motion of Andromeda and found it was so negligible that an eventual head-on collision with the […]

Hubble Spies Paired Pinwheel on Its Own

A single member of a galaxy pair takes centerstage in this NASA/ESA Hubble Space Telescope image. This beautiful spiral galaxy is NGC 3507, which is situated about 46 million light-years away in the constellation Leo (the Lion). NGC 3507’s classification is a barred spiral because the galaxy’s sweeping spiral arms emerge from the ends of […]

Hubble Spies a Spiral So Inclined

The stately and inclined spiral galaxy NGC 3511 is the subject of this NASA/ESA Hubble Space Telescope image. The galaxy is located 43 million light-years away in the constellation Crater (The Cup). From Hubble’s vantage point in orbit around Earth, NGC 3511 is tilted by about 70 degrees, intermediate between face-on galaxies that display the […]

How Big is Space? We Asked a NASA Expert: Episode: 61

How big is space? Space is really big. Thinking about our solar system, let’s imagine you could get in a car and drive to Pluto at highway speeds. It would take you about 6,000 years to get there. When we start to think about other stars outside of our solar system, we need to think […]

Discovery Alert: A Possible Perpendicular Planet

The Discovery A newly discovered planetary system, informally known as 2M1510, is among the strangest ever found. An apparent planet traces out an orbit that carries it far over the poles of two brown dwarfs. This pair of mysterious objects – too massive to be planets, not massive enough to be stars – also orbit […]

Hubble Pinpoints Young Stars in Spiral Galaxy

In this image, the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, located more than 50 million light-years from Earth. Visible in this galaxy image is a bright blue ring that hosts hot, young stars. NGC 1317 is one of a pair, but its rowdy larger neighbor, NGC […]

Another First: NASA Webb Identifies Frozen Water in Young Star System

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system. Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a […]

Webb’s Titan Forecast: Partly Cloudy With Occasional Methane Showers

Saturn’s moon Titan is an intriguing world cloaked in a yellowish, smoggy haze. Similar to Earth, the atmosphere is mostly nitrogen and has weather, including clouds and rain. Unlike Earth, whose weather is driven by evaporating and condensing water, frigid Titan has a methane cycle.

NASA’s Webb Reveals New Details, Mysteries in Jupiter’s Aurora

NASA’s James Webb Space Telescope has captured new details of the auroras on our solar system’s largest planet. The dancing lights observed on Jupiter are hundreds of times brighter than those seen on Earth. With Webb’s advanced sensitivity, astronomers have studied the phenomena to better understand Jupiter’s magnetosphere.
