Space heaters can keep you warm during the chilly season, but using them improperly can lead to big problems.

Here's a use of AI that appears to do more good than harm. A pair of astronomers at the European Space Agency (ESA) developed a neural network that searches through space images for anomalies. The results were far beyond what human experts could have done. In two and a half days, it sifted through nearly 100 million image cutouts, discovering 1,400 anomalous objects.
The creators of the AI model, David O'Ryan and Pablo Gómez, call it AnomalyMatch. The pair trained it on (and applied it to) the Hubble Legacy Archive, which houses tens of thousands of datasets from Hubble's 35-year history. "While trained scientists excel at spotting cosmic anomalies, there's simply too much Hubble data for experts to sort through at the necessary level of fine detail by hand," the ESA wrote in its press release.
After less than three days of scanning, AnomalyMatch returned a list of likely anomalies. It still requires human eyes at the end: Gómez and O'Ryan reviewed the candidates to confirm which were truly abnormal. Among the 1,400 anomalous objects the pair confirmed, more than 800 were previously undocumented.
Most of the results showed galaxies merging or interacting, which can lead to odd shapes or long tails of stars and gas. Others were gravitational lenses. (That's where the gravity of a foreground galaxy bends spacetime so that the light from a background galaxy is warped into a circle or arc.) Other discoveries included planet-forming disks viewed edge-on, galaxies with huge clumps of stars and jellyfish galaxies. Adding a bit of mystery, there were even "several dozen objects that defied classification altogether."

A good home theater setup goes beyond just having the right TV (although that certainly does help a lot). Getting the right sound for your space, the right lighting and making sure your streaming gear is up to date are all things that can go a long way to making your setup feel premium.
And don't think that just because you're not hosting movie night every weekend that a good home theater setup is a waste. Whether your family is full of cinephiles, you love playing video games with your kids or you plan on hosting friends to watch Super Bowl 2026, the right home theater equipment can make your experience much better. We test a ton of that technology here at Engadget; if you're looking to make some changes to your setup, we've collected some of our favorite home theater gear here to make your shopping list a bit easier to compile.

A rare visitor from another star system has been spotted: the interstellar comet 3I/ATLAS! It was detected July 1 by the NASA-funded Asteroid Terrestrial-impact Last Alert System, or ATLAS. Most known comets orbit the Sun and are bound by the gravity of the solar system ... but this object came from far beyond the pull of our Sun, traveling 137,000 miles per hour from another star. Now, scientists are racing to get a good image of it, in the hopes it can answer big questions like: What is the universe like where this comet is from? Is the solar system we live in unique?
