I get a popup but I clicked the x and I had not issues reading it. On linux but no adblocker here... strange you are getting that. Wait, now it's paywalled WTF. Dammit. I'll see if I can fix. So the issue is the foreign body looks like much of it was like 1/2 mm thick, and it accelerated too much going around the sun, and it was very reflective vs the amount of heat it gave off, so it looks like a spaceship powered by a solar sail. It's a long interview with a scientist who talked about how instead of delivering people final results like elites, scientists should be honest when they are not sure but share their thinking process. Well I'll see if I can unpaywall it somehow.
Nah it's a good article IMO and no wall for me ... strange I'm not using popup blocker either. [Edit dammit now it's paywalled for me] Sorry
Pay/login wall
