And Vanguard-1 is still in orbit....

I think you could make it to 128

I think he plays beer league hockey, so that's the draw.

That's not ancient. I have neckties that are older.

I haven't started a paper that way for about 20 years now. The fact that there are large numbers of planets discovered isn't news to professionals. It's an amateurish way to begin a paper.

The rationale has always been to publish work rapidly that may affect other ongoing investigations. arXiv makes that unnecessary, except that some authors may not want to post before being reviewed. Nevertheless, on balance you are right.

Comet Ikeya-Seki, 1965....!

If Avi Loeb has been able to see so far, it's because he has stood on the shoulders of giants like vonDaniken.

Jar opening is a solved problem in technology. Oxo sells a jar opener that makes it easy.

It "defies the rules of planet formation" because it isn't a normal planet. It's the stripped core of an AGB star.

Well, it wouldn't be SkyNet if it wasn't in the sky.

John Carter was here.

I have to admit that I'm not pissed off at Avi Loeb. I just ignore that stuff, I have my hands full with real work.

They might mean GISS, not GSFC per se. But still bad for GSFC.

It's my understanding that Venezuela has the world's largest proven oil reserves. Look it up - wikipedia.

Was the central pressure of Camille measured?

Ah, I see the difference. Google AI gave me the wrong number for the TNT, but then several lines later it quoted the correct number, without even commenting on the contradiction. I should remember that AI has to be checked carefully. (so, what good is it?)

If you're referring to mc^2, then your math is off. An ounce is 28 grams, and mc^2 = 2.5e22 ergs = 60, 000, 000, 000 tons of TNT.

According to Google AI, the total active-duty military payroll is $200 billion per year. 130 million will pay for about 6 hours of military payroll, if I did the math correctly.

I'm certain that the number submitted is over 2900, and good chance that it hits 3000

16.10.2025 14:23 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 0 ๐Ÿ“Œ 0

We're over 2900 proposals, based on the latest minus earliest id numbers I've seen. Good chance that we hit 3000.

16.10.2025 13:38 ๐Ÿ‘ 1 ๐Ÿ” 0 ๐Ÿ’ฌ 0 ๐Ÿ“Œ 0

at 1:40 PM the number was already over 2100

over 2100 proposals at 1:40 PM.

Numbered citations save space. Especially important for Cycle-5 proposals.

Did you read the short story the film is based on? ("Farewell to the Master" by Harry Bates.) Klaatu is not who you think he is.

Exoplanet polarization has a checkered history, but I tend to believe this result, albeit for my own reasons.

And they probably have a significant effect on the radial velocity of the Sun-as-a-star. The NEID spectra will tell...
