In addition to the supermassive black hole at the center of our galaxy, the Milky Way also serves as home to smaller stellar black holes that form when a massive star collapses. Scientists believe there are 100 million stellar black holes in our galaxy alone, but most of them have yet to be discovered. The ones that had already been found are, on average, around 10 times the size of our sun, with the biggest one reaching 21 solar masses. Thanks to the information collected by the European Space Agency's Gaia mission, though, scientists have discovered a stellar black hole that's 33 times the size of our sun, making it the biggest one of its kind we've ever seen in our galaxy so far. It's also relatively close to our planet at around 1,926 light-years away.
Gaia BH3, as it's now called, was first noticed by a team of ESA scientists poring over data from the mission to look for anything unusual. An old giant star from the nearby Aquila constellation caught their attention with its wobbling, leading to the discovery that it was orbiting a massive black hole. BH3 was hard to find despite being so close — it's now the second closest known black hole to our planet — because it doesn't have celestial bodies close enough that could feed it matter and make it light up in X-ray telescopes. Before its discovery, we'd only found black holes of comparable size in distant galaxies.
The ESA team used data from ground-based telescopes like the European Southern Observatory to confirm the size of the newly disc

Logitech plans to launch the Signature AI Edition Mouse in April in the United States and the United Kingdom for $49.99. Though it has a dedicated AI key — you do need a dedicated AI key on your mouse, right? — the button actually launches an app called the Logi AI Prompt Builder, powered by ChatGPT.
That app is part of Logi Options , the connective software that ties many of Logitech's MX, or "Master," series peripherals (plus its Studio Series, Ergo, and others) such as keyboards and mice. When a user presses the AI prompt button on the top of the AI Edition Mouse, they're actually launching the Prompt Builder within the Options app. Existing Logitech peripherals that lack a dedicated ChatGPT key can remap another key to trigger the same function.
Prompt Builder is designed to highlight, copy, and/or edit a portion of the text you're working on. It looks like a more sophisticated version of the suggested actions Microsoft has tested within Copilot, where users can highlight a block of text, right-click it, and ask for a summary — Copilot key or not.
