Published: 30 November 2025 Interstellar comet 3I/ATLAS – also known as C/2025 N1 (ATLAS) or simply the 3I ATLAS comet – is racing out of the inner solar system after a dramatic swing around the Sun. It’s only the third known object ever seen entering our neighbourhood from another star system, and it has triggered an unprecedented response from NASA, ESA and the United Nations. NASA Science+1 As of 30 November 2025, 3I/ATLAS is: Below is where things stand today: what 3I/ATLAS is, what the latest data show and why the world has turned this icy visitor into a full‑scale test of planetary defence. Key facts about the 3I ATLAS comet

Published: November 28, 2025 Interstellar comet 3I/ATLAS – only the third known object from another star system to visit our Solar System – has just stepped into a new role. As of today, it’s the centerpiece of a United Nations–endorsed planetary‑defence exercise, the focus of a huge NASA observation campaign, and the subject of intense online debate over whether it’s a “normal” comet at all. The Times of India+2NASA Science+2 Here’s a clear, fact‑checked look at what’s actually new on 28 November 2025, why scientists are so excited, what the UN drill really means, and how you can try to see 3I/ATLAS in the sky yourself. What’s

As of Friday, 28 November 2025, interstellar comet 3I/ATLAS has gone from “weird new visitor” to the centerpiece of a United Nations–endorsed planetary‑defence drill, a live trajectory experiment using spacecraft around Mars, and a lightning rod for speculation about alien technology. The Times of India+2Universe Today+2 Over the last 48 hours (27–28 November), three big themes have emerged: Below is a detailed, news‑style rundown of what’s actually new today, why it matters, and how to follow 3I/ATLAS safely and sensibly. What’s New On 27–28 November 2025? 1. UN‑Backed Planetary‑Defence Exercise Officially Starts The Times of India has confirmed that 3I/ATLAS has been formally adopted as the focus

On 27 November 2025, interstellar comet 3I/ATLAS hits a major milestone in its brief visit through our Solar System. The United Nations’ planetary‑defence network is officially turning the comet into a live global drill, while new data from spacecraft around Mars has tightened its predicted trajectory by a factor of ten.Universe Today+1 Here’s what’s happening today, why scientists are so excited — and why you absolutely don’t need to worry about a doomsday comet. What is 3I/ATLAS, and why is it such a big deal? 3I/ATLAS is the third confirmed interstellar object ever seen passing through our Solar System, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. It was

As of November 27, 2025, Earth’s newest interstellar visitor is back in the pre‑dawn sky, at the center of a United Nations planetary‑defense exercise and a wave of viral speculation. Here’s what’s actually happening with comet 3I/ATLAS today. Quick overview – what’s new on November 26–27, 2025 Over the last 24 hours, several key developments around 3I/ATLAS have hit the news: With that context, let’s zoom out, then back in, on what 3I/ATLAS actually is and why today matters.

Published: November 25, 2025 As the interstellar comet 3I/ATLAS speeds out of the inner solar system, the story around it is accelerating just as fast. In the last few days NASA has released a flood of new images and animations, the United Nations has confirmed that 3I/ATLAS is at the center of a global planetary‑defense drill, and a high‑profile podcast has reignited debate over whether this icy visitor could be “something alien.” NASA Science+2The Times of Israel Blogs+2 Here’s what we actually know today about 3I/ATLAS — and what’s speculation.

Updated 18 November 2025 Interstellar comet 3I/ATLAS is having a huge day in the headlines. As of today, 18 November 2025, astronomers have unveiled a spectacular new multi‑tailed image, NASA has confirmed details of a live global broadcast tomorrow to share the sharpest spacecraft images yet, and new research is sharpening its role as a test case for defending Earth from future cosmic intruders. At the same time, fresh comments from Harvard astronomer Avi Loeb are reigniting online speculation that 3I/ATLAS might be something more than a comet – speculation that most planetary scientists still firmly reject. www.ndtv.com+2Sky at Night Magazine+2 Key 3I/ATLAS updates for 18 November 2025 What
