 Keep your eyes peeled for this comet in 2023

A comet glows white and green.

Here’s something to look forward to in the new year: 2023 could give us a once-in-a-generation chance to see a new comet grace our skies.

Stargazers can keep their eyes peeled for Comet C/2022 E3 (ZTF) throughout January and early February, although they’ll need a telescope or binoculars to spot it at first. As the comet races closer to Earth, however, there’s a chance the comet could become visible to the naked eye under dark skies. If that happens, it’ll be the first comet to reveal itself to the unaided eye since NEOWISE passed us by in 2020.

This new comet was discovered last March while it was within Jupiter’s orbit. The comet’s current trajectory should bring it closest to the sun by January 12th. On February 2nd, according to...

Pandora Stories lets artists add commentary to their own playlists

Pandora launched Stories today, a tool that lets artists and creators add voice commentary to their own playlists.

Instagram’s updated algorithm prioritizes original content instead of rip-offs

Image: Kristen Radtke / The Verge Instagram is making significant changes to how its system recommends content, with a focus on original content and increased distribution for smaller accounts. The slew of changes were announced by the company in a blog post today. The biggest change deals with aggregators — accounts that download or screenshot other users’ videos and photos and repost them. Sometimes aggregators will credit the original poster by tagging them in the post or caption, but often, content is wholesale ripped off with no acknowledgment, and engagement is siphoned off from the person who created the content in the first place. Instagram clearly has a problem with this and will begin removing reposted content from recommendations across the platform. The...

We asked camera companies why their RAW formats are all different and confusing

When you set up a new camera, or even go to take a picture on some smartphones, you’re presented with a key choice: JPG or RAW? JPGs are ready to post just about anywhere, while RAWs yield an unfinished file filled with extra data that allows for much richer post-processing. That option for a RAW file (and even the generic name, RAW) has been standardized across the camera industry — but despite that, the camera world has never actually settled on one standardized RAW format. Most cameras capture RAW files in proprietary formats, like Canon’s CR3, Nikon’s NEF, and Sony’s ARW. The result is a world of compatibility issues. Photo editing software needs to specifically support not just each manufacturer’s file type but also make changes for each new camera that shoots it. That creates pain for app developers and early camera adopters who want to know that their preferred software will just work. Adobe tried to solve this problem years ago with a universal RAW form...
