Hubble has captured the Cat’s Tail around Beta Pictoris in visible light for the first time, revealing scattered starlight from a feature Webb had previously seen in infrared. The study, led by University of Arizona researcher Arin Avsar, combines six Hubble observations taken between 2012 and 2025. The team interprets the dusty structure as possible evidence of a collision between large planetary bodies—but the collision itself was not observed. 30

Two telescopes, different views of the dust
Webb first revealed the Cat’s Tail through mid-infrared observations, which detect heat emitted by dust. Hubble’s Space Telescope Imaging Spectrograph (STIS) instead records visible light scattered by material in the system. Together, those views let astronomers examine the same dusty feature in different ways. 1

The new result draws on six Hubble observing epochs spanning 2012–2025, according to the study’s abstract. 30 In the visible-light image, the tail looks shorter than in Webb’s infrared view: dust farther from the star reflects less light, making it harder to see at these wavelengths.

A collision is a leading explanation, not a witnessed event
The researchers’ interpretation connects the tail to a collision between large bodies, possibly comparable in scale to Pluto. The University of Arizona describes the dust cloud as a possible aftermath of two or more Pluto-sized objects breaking apart into tiny grains. That is a proposed origin based on the observed structure—not a direct observation of the impact. 13

Reporting on the study also points to carbon-rich material as a possible reason the feature was hard to detect in visible light: long carbon chains can absorb visible light. 18 The available evidence does not establish every detail of the grains’ composition or how they formed, so those specifics should be treated cautiously.
Why the discovery matters
Beta Pictoris offers astronomers a nearby setting—about 63 light-years away—in which to study a debris disk, possible recent collisions and interactions between planets and disk material. Research on the system describes its combination of a well-studied disk and giant planets as useful for testing planet–disk interaction models and investigating planetesimal collisions. 18

Seeing the Cat’s Tail in both infrared and visible light adds another observational clue to that work. It does not, by itself, prove exactly what collided or reveal the full history of the dust. Instead, it gives researchers a new way to compare the feature’s appearance across wavelengths and investigate how planetary systems change as they evolve.
