星际彗星3I/ATLAS揭示异常成分及古老起源

"...friendly (it is friendly, right?)..."

"...it's also visiting from long, long ago..."

"...our friend (it is a friend, definitely)..."

"...it's a time traveler..."

"...hey, wait!..."

"...Pretty exciting...."

"...So far, the answers are looking... really weird...."

"...Yes, that kind of cyanide...."

"...which makes me much less likely to visit one personally...."

"...Don't worry, it gets stranger...."

"...The spooky part is that nickel normally wouldn't evaporate at the visitor's current distance from the Sun...."

"...What's going on there? Unclear!..."

"...At least it's not doing anything truly bizarre, like also showing signs of iron. Oh wait. There's that too...."

"...Obviously, there's a lot for scientists to figure out here...."

"...What has it seen on its long travels across space and time, and what will it tell us?..."

"...And we don't have much time to find out...."

"...Only the third interstellar object ever spotted in our part of the universe, 3I/ATLAS is just transiting through our neighborhood...."

"...Arcing in the Sun's gravity right between Earth and Mars, it will simply wave hello and goodbye before exiting the system and diving back out into the rest of the galaxy...."

"...Bad luck means that the Earth will be on the other side of our star on that date, so we won't get to observe what happens to the comet when the heat is most intense...."

"...We humans only first started noticing foreign visitors in our neighborhood in 2017, and fantastic new telescopes like the Rubin Observatory will only make us more able to spot them...."

"...So whatever questions 3I/ATLAS leaves unanswered, we may be able to ask the next friend to come along...."
