Spider megacity discovered inside sulfur cave

Back on planet Earth, and deep inside a pitch-black, sulfuric cave on the Albanian-Greek border, we reported on a study that discovered a spider ‘megacity’ — containing over 111,000 arachnids forming a web that may be the largest ever found.

If you didn’t get enough chills and thrills from the Halloween weekend, take a peek at this video of one researcher gently pressing on the spongy web with his bare hand. I’ll keep my desk job, thanks.

Comet me, bro

Good morning, science fans. Ben Turner, Live Science’s Acting Trending News Editor, here to smash a big bottle of champagne (or in my case a mug of coffee dregs) on the bow of this blog.

Leading our coverage this morning, as they have been all week, are updates on Comet 3I/ATLAS, the fascinating third-ever interstellar visitor to our solar system being tracked by astronomers as it peeks out from behind our sun. The comet, which is 7 miles (11 kilometers) wide and traveling at 130,000 mph (210,000 km/h), has rapidly brightened as it neared our sun, changing colors three times as it sheds its highly-irradiated coma.

Before you ask, no, it’s almost certainly not an alien spaceship. But that doesn’t mean the more than 7 billion-year-old object doesn’t have a wealth of secrets to offer us about its distant home star system. We’re working on a trail of exciting updates to this story, so keep comet-ing back.

Good morning and welcome to the Live Science news blog.

But we are just a small bunch of humans, and to paraphrase the late, great Douglas Adams’ “Hitchhiker’s Guide to the Galaxy,” science is big. Really big. You just won’t believe how vastly hugely mind-bogglingly big it is.

While we cover the most important or interesting topics of the day, there is no way we can report on it all, not even using AI (and we are very clear about how we use it. TL;DR — we don’t).

So rather than letting good news pass both you and us by, why not share it in one place? That way you can let our experienced journalists filter through the noise and bring you the latest science news that matters, wherever it comes from, often with their own spin on things.

Obviously you’ll read the best of Live Science here as soon as it’s published, but that will sit alongside everything else that matters: Whether it’s a scientist voicing their thoughts on a controversial study, another publication’s insight into how health research is being impacted by government policy, or a roundup of the latest science news from across the web.

So remember to stay curious and check back every day for good science.
