According to an analysis of the new images from the NASA/ESA Hubble Space Telescope, the nucleus of 3I/ATLAS is between 320 m (1,000 feet) and 5.6 km (3.5 miles) across.

The new Hubble observations allowed astronomers to more accurately estimate the size of the comet’s solid, icy nucleus.

“The upper limit on the diameter of the nucleus is 5.6 km, though it could be as small as 320 m across,” University of California, Los Angeles astronomer David Jewitt and his colleagues said in a statement.

“Though the Hubble images put tighter constraints on the size of the nucleus compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble.”

“Observations from other NASA missions including Webb, TESS, and the Neil Gehrels Swift Observatory, as well as W.M. Keck Observatory, will help further refine our knowledge about the comet, including its chemical makeup.”

      Just remember - Microsoft is a trillion dollar company. They didn't have to raise the price this high. They chose to.
    • PowerToys is getting a new window management utility

      By TarasBuria · Posted

      PowerToys is getting a new window management utility by Taras Buria If you use PowerToys on Windows 11 or 10, you probably know that the app has quite a few utilities for window management. Fancy Zones, Always on Top, Crop and Lock, just to name a few. Soon, Microsoft will add another one, and fans of Alt + Tab should be excited. Proposed by Clint Rutkas, the module has a very simple idea: use a keyboard shortcut to toggle between windows within one app. For example, if you have four browser windows open, Alt + ` will let you switch between them just like Alt + Tab switches between all running apps. Here is the utility description from its GitHub pull request: Like other PowerToys utilities, Alt Window Cycle will offer shortcut customization. You will be able to use default shortcuts (Alt + ` for the next window or Alt + Shift + ` for the previous one) or remap them to something else. For now, there is no information on when Alt Window Cycle will arrive, so we will have to wait for the next PowerToys feature update (Microsoft usually pushes them on a monthly basis). Recently, Microsoft released version 0.100, which reworked the shortcuts guide, introduced an extension gallery for Command Palette, and more. Shortly after, version 0.100.1 arrived as a bug-fixing update. PowerToys is available on Windows 10 and 11, and you can get the app from the official GitHub repository, the Microsoft Store, or winget. Although Windows 10 is no longer supported, PowerToys developers currently do not plan to drop the now-unsupported operating system. And with Microsoft giving Windows 10 one more year in the Extended Security Update, you can expect PowerToys to remain available on Windows 10 for quite a while.
