Hubble Spies an Active Spiral
Hubble Spies an Active Spiral

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, […]

NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date
NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date

NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere. Both sense sunlight reflected from Saturn’s banded […]

Optical Vortex Phase Masks for the Detection of Habitable Worlds 
Optical Vortex Phase Masks for the Detection of Habitable Worlds 

A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of starlight suppression needed for future space observatories to pick out very faint habitable exoplanets from the far brighter glare of their stellar hosts. 

NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion
NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published […]

NASA’s Hubble Unexpectedly Catches Comet Breaking Up
NASA’s Hubble Unexpectedly Catches Comet Breaking Up

In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]

NASA Discovers Crash of Extreme Stars in Unexpected Site
NASA Discovers Crash of Extreme Stars in Unexpected Site

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before — and it may help solve two outstanding cosmic mysteries. A paper describing these results […]

Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra
Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra

In late February, people in the Northern Hemisphere can look up for a special sight : Six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released [day of week] will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around […]

NASA’s Webb Examines Cranium Nebula
NASA’s Webb Examines Cranium Nebula

Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star.  Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the […]

Young ‘Sun’ Caught Blowing Bubbles by NASA’s Chandra
Young ‘Sun’ Caught Blowing Bubbles by NASA’s Chandra

For the first time, a much younger version of the Sun has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas […]
