@depth386 22 күн бұрын

I offer two scenarios. First: The planet is larger than earth so I consider it possible that the core takes longer to solidify. Basically, the magnetosphere lifespan could have a exponential or even logarithmic relationship to planet radius or diameter. One more possibility is that gas is being literally baked out of the rock due to sufficient energy, replenishing the gas lost to outer space. In such a scenario, the thickness and overall pressure of the atmosphere at surface level is the balance between the gas lost to outer space due to solar radiation and proximity to the star, versus the replenishment of the gas from the intense energy causing said gas to be released from rock. There have been some studies about humans potentially extracting oxygen from rocks on the moon or Mars, but it requires extreme amounts of energy. Basically something a Fusion enabled society might do. So it makes sense if a “hell planet” close to a star does this.

We can't even find Planet 9 but they expect us to believe they know the atmospheric contents and surface temps for planets that are allegedly, at most, a couple sizes larger than Jupiter. In the cosmic scheme of things, a planet is so small to begin with. I would think that even with the best telescopes, one would appear to us, from such a distance, as a single pixel of information, at the absolute best. I'm also very skeptical.

@jameshall1300 22 күн бұрын

These exoplanet readings are taken by light coming directly from the star itself after being filtered through the edge of the planet's atmosphere. It's much easier to do that with all of a star's light available than to essentially blindly search for an object that doesn't emit any of its own light purely by occultation of a star or the extremely tiny amount of reflected starlight from our sun. In the exoplanet case, we know exactly where to look, we just need to wait for the optimal alignment. Any planet 9 search is like looking for a needle in a haystack the size of Texas in the dark.

I grew up watching the amazing footage of the Pioneer Mission, followed by Voyager, Skylab, and the development of the shuttle which occured while I was in High School in the early 80's. I became a major science and Science Fiction fan hrowing up; and experienced the switch from analog electronics, to digital electronics. I atill remember the hand held elwctric games of my childhood; that used light emitting diodes, then the ones with simple liquic crystal displays. Seeing what has occured in what is hopefully just the first half of my life; I can only imagine where space wxploration, science, amd technology will be in the next 25, 50, or 100 years. From what I see abundant and low cost wnergy is just around the corner; and that will change the gave of aociety. I keep seeing progress with fusion twchnology; which will someday power our space ahips, space stations, and space collonies. If I live to see the future technologies and maned space colonies seen in the scifi series The Expanse; I will die a happy man.

I'd expect a boat load of sulfur compounds bubbling up from the magma. Most likely, volatiles trapped in the mantle are bubbling out gradually over time. This, along with the temperature difference, should increase the convection in the mantle greatly compared to Earth, which would help delay the loss of all the volatiles through getting baked out. So, I guess my prediction (which can't be tested without going there and digging in the mantle, but is _technically_ testable?), is that the night side has more volatiles trapped in the mantle than the day side, but much less than we'd expect in the absence of super convection stirring things up.

How is this even possible? I thought the only way to discover planets around a star (even the closest star) was to detect the brightness dim. So I don’t really believe if that’s the case that you can detect anything else about the plant, I would even question that you know for sure that the dimming of a star can confirm that it’s a planet!

@jameshall1300 22 күн бұрын

There's multiple ways. Transit method ( dimming ) and radial velocity ( the wobble of the star due to the gravity from the planet ) are the two I've heard the most about. For these readings, they take multiple spectrograph readings from the star when the planet passes in front, and using a baseline from the star itself, you can see what is missing from the spectrograph reading when the light passes near the planet. Those missing spectra are what are used. It's no different than doing transmission spectroscopy on earth, just on a much much larger scale. We've been taking spectra of stars for well over a century now.

I first read “JWST finds EXTINCT atmosphere..” after learning yesterday that one of the ways its looking for alien life is by sign of them having already destroyed their planet and went like “WHAAAT!?”

It is beyond astonishing that scientists are now able to measure details about planets so far away - even more so considering that we only recently confirmed the existence of such planets outside our own solar system in the first place. Fascinating times

They said Webb is revolutionizing astronomy, but everything is so slow: we are talking about Trappist star system again and again, find new systems already!

I can safely theorize that any planet with liquid water in a habitable zone would support some sort of life ! There are probably billions of planets out there !

We know so much, yet so little.

no, we know enough to know how little we know, it being a lot is just how limited our capacity is in relation to the information, not the amount of information we know, nearly nothing.

Earth, circa 2090: "Sir! Sir! We have received a reply to the message our great grandparents sent to 55 Cancri e!" "Well, has it been translated?" "Yes, Sir! We've just completed the task!" "Well, spit it out! What does it say??" "OK, let's see here...'OW'...another 'OW'...then 'OUCH MY FEET ARE BLISTERING'...and finally...'HURRY, SEND AIRCON'...and that's it, Sir!" "Astonishing! Quickly! We must let the Earth Council know! Tell them that we have decoded the 'OW' signal!"

9:30 atmospheres can last long, can be created by various planets and can contain volatiles

Have we found any planets in orbits that don't cross between us and the star? Considering the number of "nearby" planets, it seems that there must some of every imaginable configuration even in this one galaxy.

Hello Anton, can you explain how we are so sure this information prove what they say?

@darkzq 22 күн бұрын

So… its so hot we wouldn’t last a minute. Welp, it’s still nice to discover planets with atmospheres and volatiles and what not.

I wonder would it be a waste to get the jwts to look out towards voyager 2, it would be a great picture beside the pale blue dot

Planet f in this system is very interesting. 55 Cancri A star is slightly smaller and less luminous than the Sun, and Planet f is in an orbital distance almost the same as Venus. This puts it within 55 Cancri A's habitable zone. It's a sub-Saturn-mass planet, and could host a large moon stably. This moon would be able to host liquid water, and since it would be orbiting the parent planet likely in several days to a week or two, it would be protected from tidal locking relative to the star, and have a day-night cycle. Interestingly, it would also have a situation where one side of the moon could experience a 'double day', since the side facing the planet would be eclipsed by the large planet every orbit if it's in a planar orbit with the star. This might result in a more habitable side of the moon, especially if the orbit is on the slower side, since when that side faces the star, it experiences a second 'night' of the eclipse that will let it cool off again. That side of the moon is also further away from the star when it is facing the star, and thus will not heat up as much. The outward-facing side of the moon, however, will have much more extreme temperature swings. It faces the star when the moon is closest to the star, and away from the star when the moon is at its farthest. Given the dramatic differences in temperature variations between the two sides of the moon over the period of a typical Jovian moon's orbital period, I would expect it would host powerful winds and raging storm systems if it has a significant atmosphere.
