Read previewThe weeks leading up to Monday's total solar eclipse became even more exciting when astronomers announced that comet 12P/Pons-Brooks, also known as the "Devil comet," might be visible during totality. Where it all went wrongEven in the darkness of totality, I wasn't able to spot the "Devil comet" with my naked eye or my camera. But instead, I shot vaguely in the direction of where I thought the comet might be, and only captured darkness. All in all, I learned that photographing a comet with a standard DSLR is tricky. And in general, I wouldn't recommend trying to snap a picture of a comet during a total solar eclipse.

Comet Nishimura appears in the night sky through September 13, before skimming past the sun. Here's how, where, and when to spot Comet Nishimura before it might burn up and disappear forever. Advertisement Advertisement Watch: How NASA spent $10 billion on the James Webb telescopeAfter passing our planet, Comet Nishimura will continue careening toward the sun — and possibly its own destruction. How, when, and where to spot Comet NishimuraA photographer attempts to capture the comet Neowise from Trwyn Du Lighthouse, Anglesey, Wales. Carl Recine/ReutersFor now, Comet Nishimura is only visible in the Northern Hemisphere.

I tried to see the famous green comet in the night skies, far from the city, last weekend. The moon outshined most of the stars, and I couldn't locate the faint comet, even with binoculars. I've heard (and written) a lot of hype about this comet, called C/2022 E3 (ZTF), or Comet ZTF for short. Morgan McFall-JohnsenIf I had spotted the green comet, there's no way I would've been able to capture it on my iPhone X. Who knows, maybe I looked right at the green comet and didn't recognize it because it was too faint.
A green comet and Mars will appear side-by-side in the night sky on February 10 and 11. The green comet and the red planet will be visible side-by-side across the Northern Hemisphere on the nights of February 10 and 11. All that could make it much easier to spot the cosmic visitor, a ball of frozen gas and dust called Comet C/2022 E3 (ZTF), or Comet ZTF for short. Once you spot Mars, finding the green cosmic snowball should be a breeze if it's bright enough. How to see Mars and Comet ZTFThe Hubble Space Telescope took this snapshot of Mars in the 1990s.
Nicknamed "dirty snowballs" by astronomers, comets are balls of ice, dust and rocks that typically hail from the ring of icy material called the Oort cloud at our solar system's outer edge. One known comet actually originated outside the solar system - 2I/Borisov. Comets are composed of a solid core of rock, ice and dust and are blanketed by a thin and gassy atmosphere of more ice and dust, called a coma. Its greenish, emerald hue reflects the comet's chemical composition - it is the result of a clash between sunlight and carbon-based molecules in the comet's coma. NASA plans to observe the comet with its James Webb Space Telescope (JWST), which could provide clues about the solar system's formation.
A rare green comet is flying past Earth in late January and early February. Comet ZTF hasn't passed our planet since the last Ice Age, and humans may never see it again. These stunning photos show what you could see if you spot the green comet in the night sky. If you catch Comet ZTF with a telescope, you could see something like this:Comet ZTF, as photographed on January 18, 2023. Want to see the green comet yourself?
A perfect example of this is the viral technology ChatGPT. ChatGPT makes a lot of people nervous (here's everything you need to know about it, BTW). Or maybe one day ChatGPT will just teach the class — that's probably part of Google's AI nightmare. If ChatGPT runs rampant, the search giant fears it could ruin AI adoption for everyone. My colleague Hasan Chowdhury breaks down how so-called generative AI — not just ChatGPT — could derail an entire sector of emerging technology.
