Imaging Exoplanets with the Solar Gravitational Lens
The Sun's gravity can be used like a lens to focus light allowing us to get a high quality image of an exoplanet. The best we've got are tiny fuzzy dots, and those are for gas giants larger than Jupiter. With this method, solar gravitational lensing, we could analyze the exoplanet's atmosphere for signs of life and habitability.
Link to the paper "Diffraction of Electromagnetic Waves in the Gravitational Field of the Sun" by Slava G. Turyshev, Viktor T. Toth:

@@Jimiticus If we can see them, they can see us. Other civilizations in the galaxy could have tech that is thousands or millions of years more advanced that our own. Some civilizations could have thousands of these "telescopes" positioned around various stars scanning for habitable worlds. We are not the tiny, innocuous spec of blue/green we think we are. Rather chilling, I think, to consider the implications of this technology.

Imagine what you could do with a black hole as your gravitational optic. This reminds me of a really cool short story (can't remember the name of it, sorry) about a woman who was part of a team using some kind of special telescope that could see human scale details on an exoplanet in full real time. Their job was to find any scientific discovery that could be used here on Earth, with only the visual available to them. I think the story was left unfinished, which was too bad because it was a really neat concept.

Great video :) I recall vaguely wondering about using the sun as a telescope lens when I first learned about General Relativity, and how the mass of stars bends light. The location of the focal line is so far away. Would a telescope mission need to slow down when arrived there, or would its trajectory just carry it along the line in the time needed to make observations? How would the lengthy pixellated image reconstruction process take account of the possible rotation of the target exoplanet?

And even though you no longer making videos, I will always remember your work on KZread, which is no easy work, especially today.
Couldn't you use Jupiter and Saturn to further bend the light so the focal points would be at a closer distance than 650AU (30 yrs away)????

Maybe … but even if, that would only work for a fleeting moment when the sun, Jupiter and Saturn line up in a row from the telescope's point of view.
Eow this video was really good very impressive
That is so dope
that was so interesting.
An excellent piece. 30 years of mission time is a long wait so I think we would need improvements in propulsion first to be practical, particularly as you would want to view more than one object. One small correction: you said the exoplanet rotates on its axis if not tidally locked to it's star. Tidally locked planets do rotate, just the period of rotation matches the orbital period.
@Jimiticus
7 жыл бұрын
Thank you! Yes, 30 years is quite the long wait, but honestly, if we could launch a mission today that can get these sorts of results, wouldn't you do it? I'd still be incredibly happy to see a high resolution image of an exoplanet, even if I'd be 65 :). Who knows how long it will take to get better propulsion technology. Even if breakthrough starshots succeeds, I don't know if it's a practical design for studying the solar gravitation lens, but I could be, and often am, wrong. Your totally right about the tidally locked planets, I think I just wanted to mention the possibility without going into too much of a tangent. That a maybe lazinness :)
@davidmurphy563

The value would be undoubtedly enormous and long term missions pay huge dividends as we've seen time and time again. On reflection, my point would be that you risk launching a craft now just to see it overtaken by a technologically superior craft before it reaches its destination. Even with today's tech, infrastructure & offworld rocket manufacturing / assembly in shallow gravity wells does wonders for the rocket equation. I see a strong case for building up to this and leaving the fruits to future generations. Or taking a different approach and accelerating mircocraft on lasers as you mention, although I agree this presents its own set of challenges. Ps. I'd be 72... Gulp!
@Jimiticus

Ya getting overtaken would definitely suck! But it's hard to think of any technology on the horizon that could really do that within 30 years. Maybe some next generation ion engine. Well hopefully we'll be old men enjoying the fruits of our optimism :)

Perhaps you're right, barring fusion there are no obvious game changers on the horizon. Even metallic hydrogen wouldn't really give you the SI for the hundreds of AU range - that's crazy far and you have to achieve orbit not a flyby... So the ion you mentioned with extreme grav assists is likely optimum for the foreseeable. Hmm.. Might be an idea to quit smoking...! A high res of an exoplanet would be a ground-breaking moment for humanity to witness. Just hope it's not a Titan analogue!
@Jimiticus

Fusion is definitely exciting for future crewed spacecraft as solar/ion isnt practical for larger mass spacecrafts I think they would skip the Titan planets :). I feel they would only send a craft if it was already thoroughly studied, like if the Trapist system turns out to be promising for life

5:57. When you say the spacecraft and counterweight can be brought closer together, doesn’t that result in the spacecraft beginning to speed up? I don’t have much knowledge in physics but I know when you hold a book in each hand with arms extended on a spinning chair, you spin slower. But when you bring your arms in with the books, you speed up. Would that not happen with the spacecraft? And if so, what changes would have to be made accordingly? (Edit: by changes I mean concerning the photographing aspect of the exoplanet).
*Just a thought* How about the idea of creating artificial small temporary black hole to achieve gravitational lensing maybe not the size of the Sun but more practical due to shorter distances needed to place telescope (& artificial black hole) at more convenient/achievable position.
It's a nice idea but it's pretty much a one-shot device as you cannot point the telescope in any direction. It always has to point towards the sun meaning you'd have to wait thousands of years for the telescope to line up on secondary targets..

I know zilch about rocket science... but instead of travelling all the way to the focus point ~550AU away from the sun, would it be possible to just send the telescope to the nearest light ray away from earth, and then slowly circle around earth along the light ring? Or circle around the light ring while getting closer to the focus point (in a cone shape)? This way we would get data sooner, and wouldn't have to worry about the heat shield. Great video by the way.
