Comet Atlas is now in an all-out death dive towards the sun

  Comet Atlas is now in an all-out death dive towards the sun It shone bright for a bit, and now it's disintegrating as it hurtles towards our star.In March, newly discovered Comet Atlas was going through a rapid brightening phase and some astronomers were hopeful it might put on a spectacular show in the night sky as it flew closer in May. Just a few weeks later, though, it became clear that Atlas probably wasn't going to live up to those expectations as it began to break apart.

COMET ATLAS , the space rock which has piqued the interest of the astronomy community, has started to crumble as it approaches the Sun, experts Karl Battams of the Naval Research Lab in Washington DC said: “ It ’ s possible that this is the beginning of the end. "The comet ’s orbit is now being

It takes a while for that heat to permeate through the comet , Jewitt says. Heat from the sun creeps into pockets of ice inside the comet . They might have another peculiar effect on the comet : they may cause it to speed up . More observations are needed to confirm Jewitt' s hypothesis and measure the

Comet Atlas has the potential to put on one of the best shows by a melting space snowball in years, but there's some early indications that it might be breaking up early and cruising towards a spectacular fizzling instead.

In a note shared via The Astronomer's Telegram Monday, astronomers Quanzhi Ye from the University of Maryland and Qicheng Zhang of Caltech report that Comet C/2019 Y4, or Atlas, may be falling apart.

"We report the possible disintegration of comet C/2019 Y4 (ATLAS)," they wrote. "Images taken on (April 5) showed an elongated pseudo-nucleus... as would be expected from a major disruption of the nucleus."

The comet C/2019 Y4 ( ATLAS ) has been fading in brightness in the past few days as it approaches the sun, sparking concerns that it could be disintegrating. The object, which was only discovered on December 29, 2019, has garnered a lot of attention recently, with many in the astronomy community

[Chorus] I don't know what it is that makes me feel like this I don't know who you are but you must be some kind of superstar coz you got all eyes on you no matter where you are (you just make me wanna play).

Or as astrophysicist Karl Battams from the Naval Research Laboratory and NASA's Sungrazing Comets Project summed it up on Twitter: "an elongated nucleus isn't a great sign."

Atlas is named for the sky survey that first discovered it back on Dec. 28. The comet went through a period of rapid brightening in March that excited some skywatchers, with hopes it might eventually become as bright as Venus and perhaps even possible to observe in daylight.

But comets are famously erratic and hard to predict. As they approach the sun, heat and radiation from our star can inflict serious damage, sending promising cosmic ice clods into early oblivion.

These latest observations indicate that Atlas is a little less likely to show off its fantastically gassy plumage next month as hoped, but Battams says it's still too early to predict its demise as well.

"The frustrating thing about comets is we often don't know exactly what they're doing or why they're doing it. There's still a chance that Comet ATLAS is just 'taking a breather' before another outburst," he told Spaceweather.com. "But I wouldn't count on it."

Intel's 10th-gen H-series laptop CPUs reach 5.3GHz .
Just like Intel said at CES, it's crossed the 5GHz barrier with its new H-series 10th generation notebook CPUs. And you won't need to shell out for the top-of-the-line Core i9 to do it: The new six and eight-core i7 processors reach up to 5.1Ghz (boost speed) on a single core. But if you want to go all out, the octa-core i9-10980HK hits 5.3GHz -- and it's fully unlocked for overclocking, to boot. As usual, these H-series chips are meant for gaming and workhorse machines, not laptops where battery efficiency is key. You can expect around 44 percent better performance in Assassin's Creed Odyssey in 1080p with high settings, compared to the three-year-old Core i7-7700HQ.
