Super-comet or super-dud? We'll see

A new comet superstar named C/2012 S1 (ISON) is heading for the spotlight starting in November 2013 ? but will it perform as some hope it will, or will it be a dud of cosmic proportions?

"This is one to watch, definitely," said Karl Battams, a scientist at the Naval Research Laboratory who monitors comets for the NASA-supported Sungrazer Comet Project. "But the astronomy community in general tries not to overhype these things. Potentially it will be amazing. Potentially it will be a huge dud."

Comet ISON quickly rose to the top of the charts after its discovery, which was based on imagery collected on Friday by the International Scientific Optical Network's 16-inch (0.4-meter) Santel reflecting telescope in Russia. The comet, which was described in an IAU circular on Monday, takes its common name from the network's acronym. Since the discovery, astronomers have gone back through their files to find "pre-discovery" images and calculate the comet's orbit.

That orbit is due to bring Comet ISON incredibly close to the sun ? within just 1.1 million miles (1.8 million kilometers) in late November of next year. As a result, current projections suggest it could get very bright. How bright? Various estimates have set the brightest magnitude at -10 to -16. That suggests the comet could become brighter than the full moon ? which led Astronomy Magazine's Michael E. Bakich to say it "probably will become the brightest comet anyone alive has ever seen."

Seems cool. Hopefully, we'll get something to look at. I haven't seen a comet since Hale-Bopp in '97.

Same here, Dot. I was disappointed because I missed this latest one...it was just too far on the horizon for me to see it from where I live. Too many houses/trees/buildings. I was disappointed. Hale-Bopp, though...I'll never forget that!! (Y)

Hale-Bopp was a great one.

Hale-Bopp was ****en AWESOME. Can't wait for this.

Any info on long it will take to pass by Earth, like how long we will be able to see it ?

I think we'll get a solid couple of weeks in Nov?

Another awesome fact is that this thing will pass nearly a million miles from the Sun traveling at, wait for it, over 400,000mph. It's going to be hauling serious ass..teroid (ok bad joke I know!). It might even be going so fast that it's orbit will be hyperbolic, meaning it will make one appearance and then leave the solar system forever. Neat eh?

I'm really hoping this one comes to life as I'm hankerin' for a good comet. I saw a very very faint PANNSTARS a few weeks ago but it was meh. My kids were like "wow... so exciting *yawn* " lol.

I hope this one makes their jaws drop. :D

    • Bypassed Windows 11 shows surprising stability on ancient, completely unsupported hardware

      By +samw61 · Posted

      Honestly that feels even more useless than it did when Win11 was first released. In 2021, the uproar was somewhat justified, but only when comparing how good we've had it since Windows 7. Prior to that, a new Windows release would often require new, or very recent hardware. Windows XP wouldn't run (in any usable way) on hardware released when it's predecessor Win98 was released (let's ignore ME). It was time to shift the goal post, and the way Microsoft did that was actually ok. People have still had another FIVE YEARS of free software support with Windows 10, and those of us who want to have used these tools to bypass the limitations, all while understanding the impacts that may have. Most laptops don't last 5 years (sadly), so now the youngest unsupported hardware is 9 years old, and apparently has another year of support with Windows 10. That's good. Meanwhile, understanding the impacts and limitations, I have my 2013 laptop running Win11 perfectly fine. The thing that's failing on it is the hardware, the 2.5" SATA cable/chip is failing and corrupting the SSDs I put in. Thankfully it has a functional M.2 sata drive that works fine!
    • iPhone 18 Pro drop-test video and photos leak on the dark web following a data breach

      By Hamid Ganji · Posted

      iPhone 18 Pro drop-test video and photos leak on the dark web following a data breach by Hamid Ganji iPhone 17 Pro - Image via Apple Apple is seemingly facing one of the biggest data breaches in its history, and just a few months before the official debut of the iPhone 18 Pro series, photos, a drop-test video, a supplier list, and key phone components have reportedly been leaked by hackers. Last week, we reported that Tata Electronics, an Apple supplier and iPhone producer in India, was hit by a data breach. As a result, it was reported that more than 200,000 trade secrets and confidential documents belonging to Apple and Tesla were stolen by the ransomware group World Leaks. According to Reuters, the group has now leaked supplier lists, component details, and photos of the upcoming iPhone 18 Pro models on the dark web. One of the materials leaked by the hackers is a drop-test video of the iPhone 18 Pro, which is due to launch this September. The phone is shown in a gray color and has the same familiar design we saw on last year's iPhone 17 Pro series. The device also appears to be quite durable, though it seems to be thicker than last year's model. One possible explanation is that Apple may be using a larger battery in the iPhone 18 Pro series. Moreover, Reuters says it has seen at least six documents mapping many components in the iPhone 18 Pro models to their respective suppliers, including details on chips on the main circuit board and on battery and camera components. The documents reportedly detail hundreds of parts that will be used in the iPhone 18 Pro models. A person familiar with the matter told the outlet that Apple classifies this data as sensitive and “is concerned about the documents being shared on the dark web as they relate to unreleased models.” Apple is reportedly investigating the issue but has yet to issue an official statement.
    • Microsoft Edge gets tons of security features, including AI model that can see your screen

      By monterxz · Posted

      You do you, I've just said that it first appeared in "home" version before it will be available in "work" one. I use Edge only because it still supports MV2 uBO extension even on Android - I'll switch when they stop.
    • Can't access the forum on mobile

      By Steven P. · Posted

      I imagine that was a review or something? My reviews mostly contain a lot of images and galleries, but these are all webp too, but yeah it all adds up on the page load. Would help if you were more helpful with your critique instead of bitching and moaning like a Karen 😂 Because then we might be able to fix it for you.
    • Dbrand thought they could get away with this Steam Machine case, Valve disagreed

      By PsYcHoKiLLa · Posted

      If Valve refused to let them make the case, I wonder if they've already partnered with someone else to do it? The fact that they didn't seek permission/licence before diving straight in is incredible though
