It's our world's first -- maybe the others already got it.

Or better, "humanity's first".

well, they are the first time they're seen on this world so I think it's fine.

There was a previous mission (Ulysses aka International Solar Polar mission) that sent back a lot of data but for whatever reason, they didn't have it send visual images. Big bright ball = no surprise, maybe.
