NASA Volunteers Double Known Population of Brown Dwarfs

A new paper from NASA’s Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project began. Brown dwarfs are balls of gas the size of Jupiter, less massive than stars.

NASA’s Hubble Dazzles With Young Stars in Trifid Nebula

This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope.

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’s Hubble Detects First-Ever Spin Reversal of Tiny Comet

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence […]

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

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

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 […]

Hubble Sees Galaxy with Dark Rings in New Light

This NASA/ESA Hubble Space Telescope image features an uncommon galaxy with a striking appearance. NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies.

AI Unlocks Hundreds of Cosmic Anomalies in Hubble Archive

A team of astronomers has employed a cutting-edge, artificial intelligence-assisted technique to uncover rare astronomical phenomena within archived data from NASA’s Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side.
