Exoplanets

Sry for short off-topic, but:

Not quite a million RPM, but 42960 RPM.

PSR J1748-2446ad is a monster indeed.

Black hole ASASSN14-li is spinning at least half as fast as the speed of light. I don't even know how much rpms is that lol

That was my point. Also preposterous.

That would depend on the diameter of it. Going backwards to % of speed of light for our spinning neutron star:

20 mile diameter = ~ 32000m
32000m * pi = circumference (~100530m)
at 716x per second = ~71980170 m/s on the surface of the equator

That should be just over 24% of the speed of light. I hope I didnt mess up anywhere, its late.

An international research team led by the University of Göttingen has discovered two new Earth-like planets near one of our closest neighboring stars. "Teegarden’s star" is only about 12.5 light years away from Earth and is one of the smallest known stars. It is only about 2700 °C warm and about ten times lighter than the Sun. Although it is so close to us, the star wasn’t discovered until 2003. The scientists observed the star for about three years.

I can't hide my excitement, this is so cool!

Very exciting indeed! This might be the best candidate for life outside our solar system to date. Both are inside the habitable zone for the star, and depending on the star's characteristics, the strength of each planets magnetic field and whether or not the planets are tidally locked, conditions might be very favorable for earth-like(carbon/water based) life.

New research suggests K2-18b, a "mini-Neptune" that lies roughly 125 light-years from Earth, could be potentially habitable.

So exciting! Could've been Earth 2.0

Earth-Size, Habitable-Zone Planet Found Hidden in Early NASA Kepler Data

While the star it orbits is much smaller than our Sun, it gets about 75% of the sunlight Earth does. NASA's Jet Propulsion Laboratory managed Kepler mission development.

The U.S. Navy has officially published three UFO videos that were previously published by the New York Times and former blink-182 singer Tom DeLonge’s UFO research group, To the Stars Academy. Together, they are three of the most famous UFO videos of all time and have spurred a renaissance in UFOlogy.

The weather forecast for the giant, super-hot Jupiter WASP-79b is steamy humidity, scattered clouds, iron rain, and yellow skies. This exoplanet orbits a star that is hotter and brighter than our Sun, and is located at a distance of 780 ly from Earth in the constellation Eridanus.

The surprise in recently published results, is that the planet's sky doesn't have any evidence for an atmospheric phenomenon called Rayleigh scattering, where certain colors of light are dispersed by very fine dust particles in the upper atmosphere. Rayleigh scattering is what makes Earth's skies blue by scattering the shorter (bluer) wavelengths of sunlight.

Because WASP-79b doesn't seem to have this phenomenon, the daytime sky would likely be yellowish, researchers say.

Can you imagine what the gravity would be on a world that large. I would not want to caught in a Huuricane. It actually brought that scene in Interstellar.

WOW!

Portrait of an exoplanet

A team of scientists from the Max Planck Institutes for Astronomy and Extraterrestrial Physics has now succeeded in obtaining the first direct confirmation of a previously discovered exoplanet using the method of radial velocity measurement. Using the the GRAVITY instrument at the VLT telescopes...

I'm in the group that thinks the governments of the world, not just the US government, knows more then they are saying..

Mathematically, it is almost statistically impossible for us to be alone in the universe. That remains true even when we narrow the scope of view down to just our galaxy.

Does anyone know if the sheer weight of the ice caps on exoplanets and our own planet affect the rotation/wobble/tilt of the planet in question, for this example: Earth at all?

I was just thinking about it tonight and thought it was an interesting question, because if that weight melts, and gets distributed elsewhere, we may have more to worry about than just rising sea levels...

 

[TheoneandonlyMrK]

Yeah, I have heard him talk in a couple of podcasts. There is strong evidence an ice age occurred 12,800 years ago and reset society so to speak, really interesting to think about this kind of stuff.

I don't understand the arguments against it.
Civilization initially hugged coastlines.
YDB submerged ALL those coastlines.

You would have to be a retard to not see that YDB ended the use of that land.

The only question is how quickly the change happened, with time for people to move, or not.

But people were not mooching around solo, even as hunter gatherer they would have been in tribes and village's IMHO.

Your not tackling a mastodon or mammoth on your own unless you're Putin.

As only K1 civilizations can be observed on a scale to detect them in a that way...so that means only: no K1 detected.

But we are still 0,73 based on energy used in 2021.

Yes it does...NASA has done that simulation (also): https://climate.nasa.gov/faq/30/if-...an-what-would-happen-to-the-planets-rotation/
