NASA’s Revised Analysis of City-Killer Asteroid: 2032 Impact Risk Reassessed in New Footage

Okay, the user wants me to shorten the original article to around 600 words and add some pictures. Let me start by reading through the content carefully to understand the key points.

The main story here is that NASA revised the impact probability of asteroid 2024 YR4 from 3.1% to 1.5%. It’s a "city-killer" sized asteroid, so the reduction is significant. The potential impact date is December 22, 2032. The article mentions that the asteroid’s trajectory is being monitored, with updated observations leading to the revised probability. There’s also info about its size, speed, possible impact scenarios, and comparisons to historical events like the Tunguska explosion. NASA’s DART mission is referenced as a possible deflection method, but there are doubts about its applicability here.

I need to condense this while keeping the essential info. The user also wants pictures. The original had several images: the NASA tweet screenshot, simulation video still, orbit diagram, artist’s impression, risk corridor map, Tunguska event photo, DART mission image. Since actual images can’t be embedded, I’ll note where to place them with captions.

Also, eliminate redundant details. For instance, paragraphs about the planetary defense techniques and the fact that the probability might drop further can be summarized. Make sure to retain the key facts: initial and revised probabilities, what happens if it hits, how NASA is tracking it, the current uncertainty, and potential deflection methods.

Check word count as I go. Need to hit around 600 words. The original looks longer, so I need to cut out less critical info. Maybe combine some paragraphs, simplify explanations. For example, the part about the asteroid moving away and becoming undetectable until 2028 is important, so keep that. The quotes from experts should be concise.

Also, the infobox with asteroid details should be included but made succinct. The "Potential Methods" section can be shortened, perhaps bullet points. Use subheadings to organize sections, making it easier to read. Ensure that all hyperlinks from the original are either removed or converted to plain text references since this is a rewrite without active links.

Make sure the flow is logical: start with the updated probability, then the asteroid’s characteristics, potential impact effects, monitoring efforts, and possible defense strategies. Conclude with expert opinions on the likelihood of impact decreasing further.

Check for any technical terms that need simplification, but since the audience might be interested in space topics, some jargon is acceptable. Also, ensure all key figures (size, speed, probability) are included.

Now, let me structure the shortened version:

• Headline
• Intro paragraph with key update
• Data on size, speed, comparison to Tunguska
• Details on revised probability and tracking challenges
• Impact simulation and risk corridor
• NASA’s DART mission and deflection feasibility
• Concluding thoughts from experts
• Infobox with quick facts
• Mention of other asteroid deflection methods in a brief section

Let me make sure each section is concise. Remove repetitive statements, like multiple mentions of the probability change. Use images to break up text, so note where images would go with their captions. Ensure the final product is engaging but within the word limit.
NASA Lowers 2032 Asteroid Impact Risk: What You Need to Know

NASA has downgraded the threat of asteroid 2024 YR4, a “city-killer” space rock initially predicted to have a 3.1% chance of hitting Earth on December 22, 2032. Updated observations now suggest a 1.5% probability (1-in-67 odds). While still noteworthy, this reduced risk offers temporary relief as scientists continue tracking the asteroid’s path.
