So, here is something wild. A comet actually blew itself to bits while passing the sun, and NASA’s Solar and Heliospheric Observatory—that’s the SOHO project that’s been running for over thirty years—caught the whole thing on camera. This was Comet MAPS, or C/2026 A1 if you want to be formal. It was heading straight for the sun on April 4 when it hit a thermal wall. It’s funny, the way the coronagraph on the SOHO works, it creates an artificial eclipse just so we can see what’s happening in that blinding glare.
The footage is—well, it’s honestly pretty cool. The comet, which was definitely a bit smaller than people initially guessed, entered the sun’s blind spot in one piece. But then, on the other side? Just a mess of debris. A total shower of dust. You can actually see this sudden brightening in the frames, which I’m guessing is the nucleus finally giving up and just exploding from the heat. There’s this pattern in the dust cloud called ‘striae’ that popped up, which happens when a comet dumps a huge amount of material all at once.
I’m sitting here drinking lukewarm coffee, thinking about how we only even found this thing back in January. At first, experts—according to reports over at Misryoum—thought maybe, just maybe, it would get close enough and bright enough to see from Earth during the day. But that didn’t happen. It turned out to be smaller than the math predicted, and it ended up flying way closer to the sun than anyone expected. It didn’t have a chance, really. Or maybe it did? No, it definitely didn’t.
Now everyone is pivoting to the next one, Comet PanSTARRS, or C/2025 R3. It’s supposed to peak in late April, staying about 46 million miles away from the sun. It’ll be closest to us on the 27th. Will you be able to see it with the naked eye? Honestly, who knows. Might need binoculars, might not. It’s always a bit of a gamble with these things.
Anyway, it’s just a reminder of how volatile the solar system really is. One minute you’re a comet, the next you’re just a cloud of dust and striae heading into the void. If you’ve got thoughts on this, or maybe a better angle on why some of these things survive and others just… well, you know.
