Are you talking about the Earth Sun Lagrange 3 point? Always opposite to the earth relative to the sun. I did some research online and couldn’t find any record of us observing it. Don’t get your hopes up though. L3 is gravitationally unstable. It is likely that nothing is there besides a weird bend in gravity.

We see it every 6 months, that's why constellations change depending on the time of year

Sorry, i get what you mean now. There are plenty of craft that can see what we cant from earth

He’s going on about the twin earth theory where there’s a second earth on the exact opposite side of the sun in lockstep with our earth so in theory we would never know what’s there unless we just leave a satellite hanging around somewhere that isn’t in a orbit around earth like mars or something

PoppersOfCorn t1_jdl6ui8 wrote on March 25, 2023 at 5:07 AM

I understand that now, but we wouldn't need a satellite(even if we have many now). We'd know by the way other objects/planets interact with it

Ok, I'm still not making this clear. If an object is in the exact same orbit as Earth but on the opposite side of the sun while moving at the same speed as Earth, we would never see it. That is the blind spot I'm talking about.

We would be able to measure how other things interact with it. But we have space craft like the Parker Solar Probe, So we do know what on the opposite side to us

VertigoOne1 t1_jdlfcjv wrote on March 25, 2023 at 6:56 AM

Any probe would be able to see it, it just needs to be not in the same orbit as earth, so even juno or, messenger, cassini and any of the probes on mars would be able to image it. Many of them have taken pics looking back.

Oh yeah. Something could hide directly on the opposite side of the sun from us, but probably not from a spacecraft in a trailing earth orbit, especially if it trailed further than like one earth radius

???? What are you talking about? Why something would be exactly at the opposite side of the sun, relative to earth? Nothing has the same speed, mass, gravity, etc to make this event possible. Are you contemplating the possibility that there’s something hidden behind the sun?

Obviously he is talking about sneaky aliens, duh.

7heblackwolf t1_jdl7mo1 wrote on March 25, 2023 at 5:16 AM

I assume that. Our own solar system has planets that differ A LOT in size, speed, orbit, material composition, etc. I think it’s more plausible to find aliens in mars than another planet hidden on the other side of the sun.

That is the well published intergalactic approach vector when observing primitive species such as Earthlings.

I believe OP is trying to describe seeing what is on the other side of the sun, at any given time, from the vantage point of earth.

To essentially see “through” the sun to observe what an earth bound viewer can never see.

7heblackwolf t1_jdlalok wrote on March 25, 2023 at 5:52 AM

I understand the question. But how and why?

phalangepatella t1_jdlato8 wrote on March 25, 2023 at 5:55 AM

Haven’t you ever been tryna sleep and some apparently world changing thought enters your mind?

OnlyAstronomyFans t1_jdl88od wrote on March 25, 2023 at 5:23 AM

I think op means the area of space directly behind the sun. The answer is yes. We rotate around the universe on several axis. The parts that we can’t see are based on the north or the south hemisphere but if you had the ability to go anywhere on our planet, you could see in all directions around the universe, and during certain times of the day and certain times of the year someone able to go to anywhere on our planet would be able to theoretically see in any direction into the universe. I hope that helps. It was hard for me to explain without drawing pictures.

wetterbread t1_jdl4evp wrote on March 25, 2023 at 4:40 AM

Yep, just wait a day then you can see that space.

We can't see on the other side of the Sun. Have we ever used satellites to see the other side?
