NASA and ESA have released new images from the Hubble Space Telescope of a comet breaking up as it exits the solar system, captured as part of study recently published in the journal Icarus. The images are notable not only because they offer a more detailed view of the inside of a comet, which could offer new information about the early days of the universe, but also because they were taken by accident.

Photographing K1, or "Comet C/2025 K1" as it's officially known, wasn't the original intention of the study. "This comet [was] observed because our original comet was not viewable due to some new technical constraints after we won our proposal," John Noonan, a research professor in the Department of Physics at Auburn University in Alabama said. "We had to find a new target — and right when we observed it, it happened to break apart, which is the slimmest of slim chances."

The comet broke up over a period of days into "at least four pieces," each with a "fuzzy envelope of gas and dust" around them, with Hubble specifically capturing the disassembly from November 8 through November 10, 2025. K1 was interesting before it started to crumble because at "around 8 kilometers across" (about 5 miles), it's larger than the average comet, and having footage of it shattering will likely offer new insights into the physics of comets in general. Additionally, the lack of carbon in the gases released by the comet as it broke is apparently "chemically very strange," which suggests the composition of K1 could bear scientific fruit, too.

Hubble has tracked comets of different sizes and compositions for years. Studying them remains a focus because comets are frequently made of ice and rock from the primordial period when solar systems were first forming. The ESA hopes to dramatically expand our understanding of that period with its "Comet Interceptor" mission, which is supposed to launch in 2028 or 2029, and aims to use photos captured from multiple angles to create a 3D model of a comet.

Horizon Worlds, Meta's first pass at a metaverse, will be inaccessible via virtual reality headset after June 15, 2026. The company shared plans to separate Horizon Worlds from Quest VR platform and focus exclusively on the smartphone version of the app in February, and now in a new post on its community forums, Meta detailed when the VR version of Horizon Worlds will be deprecated.

By March 31, Meta says individual Horizon Worlds and Events will no longer be listed in the Quest's Store and headset owners will be unable to visit worlds like "Horizon Central, Events Arena, Kaiju and Bobber Bay." Then, after June 15, the app will be removed from Quest headsets and worlds will be completely unavailable to visit in VR. From that point on, the easiest place to visit Horizon Worlds will be in the Meta Horizon app for iOS and Android.

Additionally, Hyperscape Capture, a recently added beta feature that allows Quest headset owners to capture, share and visit each other in detailed 3D scans of real-life locations, is also being removed from Horizon Worlds. Meta says users will still be able to capture and view Hyperscapes, "but sharing, inviting, and co-experiencing Hyperscapes with others will no longer be supported."

While Meta's original blog detailing its 2026 VR strategy left open the possibility that a committed Quest owner might still be able to access some part of Meta's original VR metaverse, that apparently was never the company's plan. Meta saw enough "positive momentum" focusing on supporting the mobile version of Horizon Worlds in 2025 that it made sense to completely abandon the VR one in 2026. While that seems to run contrary to Meta’s positioning as a "metaverse company," it does reflect where the company is spending the most money and seeing the most (relative) success: AI and smart glasses.

Spotify is introducing a way for subscribers to get bit-perfect playback of songs if they listen on Windows. The company's newly announced "Exclusive Mode" gives the music streaming app complete control of audio processing on your PC so you can listen to songs exactly as they were mastered.

"Without Exclusive Mode turned on, your computer may alter audio before it reaches your DAC by resampling it, mixing other system sounds in, and changing the volume," Spotify writes. With the mode enabled, all other sounds from your computer are disabled so Spotify can deliver the highest quality and most accurate version of a song possible. Exclusive Mode will help maintain fidelity while you’re playing a song, but to make sure you're not losing quality anywhere else in the chain, you'll still want to listen with wired headphones connected to a DAC or digital-to-analog converter, and opt to use Spotify’s lossless streaming option.

Exclusive Mode is only available on Windows for now, but Spotify says it'll come to the macOS version of the Spotify app "in a future release." Provided you're a Spotify Premium subscriber, enabling the feature is fairly simple:

1. Open Spotify.

2. Click on Settings.

3. Scroll down to Playback.

4. Toggle Exclusive Mode to "On" under the Output section.

Spotify launched its Lossless streaming option as a perk for Premium subscribers in September 2025. The company was rumored to be working on the feature as far back as 2017 and even formally announced it as Spotify HiFi in 2021, opening up the possibility it could be a more expensive add-on to a normal subscription. Now both lossless audio and “bit-perfect” playback are included as part of the same $13 per month you pay for a Premium subscription.
