Астрономы зафиксировали в реальном времени распад кометы C/2025 K1 (ATLAS)

"...Comets don’t usually break apart on cue...."

"...Most of the time, scientists only see the aftermath, long after the event has passed...."

"...But during a routine observation, researchers got unusually lucky...."

"...A distant comet began breaking apart while the telescope was already watching, giving them a rare chance to track the process almost as it unfolded...."

"...At first, nothing seemed unusual...."

"...Then the data came in...."

"...From Earth-based telescopes, those pieces looked like blurry dots...."

"...From space, they were clear and distinct...."

"...The irony is now we’re just studying a regular comet and it crumbles in front of our eyes...."

"...That is what makes events like this so valuable – a breakup exposes layers that have been hidden for billions of years...."

"...It gives scientists a rare look at material that has not been altered by sunlight or radiation...."

"...A mystery hidden in the dust..."

"...The timing of the breakup raised a new question...."

"...That delay does not quite add up...."

"...When fresh ice is exposed, it should react quickly to sunlight...."

"...It should heat up, release gas, and create a bright cloud of dust almost instantly...."

"...But that is not what happened here...."

"...Researchers think something slowed the process down...."

"...One idea is that a dry layer of dust formed over the fresh ice first, then blew off later...."

"...Another possibility is that heat had to sink deeper below the surface before pressure built up enough to push material outward...."

"...Never before has Hubble caught a fragmenting comet this close to ... ...."

"...Most of the time, it’s a few weeks to a month ... ...."

"...And in this case, we were ... ...."

"...This is telling us something very important ... what’s happening at the comet’s surface...."

"...We may be seeing the timescale ... ...."

"...A strange chemical signature..."

"...There is another twist...."

"...Early observations from ground-based instruments show that this comet is unusual on a chemical level...."

"...It appears to be low in carbon compared to most comets...."

"...That matters because carbon is a key ingredient in many organic molecules...."

"...Its absence could point to a different origin or a different history of heating and change over time...."

"...More detailed data from space-based instruments are expected to reveal what is really going on inside these fragments...."

"...Those results could help scientists better understand how the solar system formed and how different types of comets evolved...."

"...Drifting into deep space..."

"...The remains of the comet are now drifting far from Earth, about 250 million miles away...."

"...The fragments are moving through the constellation Pisces and heading outward, likely never to return...."

"...What started as a backup plan turned into a rare moment of discovery...."

"...A comet broke apart, and for once, someone was watching at exactly the right time...."

"...The full study was published in the journal Icarus...."
