Secret of the Ancients adventure (as well as the
update) does. But that's more of a one-off thing. It's probably best done in GURPS, simply because the support for the high-level TL gadgets are all there.
A friend ran Secret of the Ancients. At the time it was pretty interesting, if at the same time also kind of vanilla flavored. At the time (when I was younger) I did wonder why there weren't more adventures with that kind of flavor, and with flavors of higher tech and so forth. I understand much better now that Traveller is more of a "current problems now projected onto a sci-fi / space backdrop" kind of game. Therefore we see cops and robbers, political disputes, domestic uprisings and so forth, instead of mutant monsters and classic alien invasions (Aslan not withstanding).
So when I think of things like astronomy and astrophysics, and how mankind might tackle those, or tackle problems arising from them, I do think that they would make really rocking adventures and / or stories for this game, and I actually drafted a few concepts this last summer. But it's my belief that Traveller, because of the kind of RPG that it is, doesn't lend itself to that.
But I'll tell you this, I have in the past posted concepts about your standard eight man team tackling something like a kaiju monster rampaging in Efate's startown, or, say, one of the Trek monsters like the Doomsday Machine or Vampire cloud coming to wreak havoc. In that same vein monsters from Star Fleet Battles, like the Starswarm, or Moray Eel of space, would simply be too much for your TL15 team of adventurers ... though most entertaining to watch from a GM's standpoit; GM/Referee -----> :devil:
arc-seconds would be traveling across our view of that star.
That page has the animation I've always seen, a dot moving past other stars over a period of decades.
It isn't moving so fast you can see it move, it just means star charts for 1950, showing its position, are very much out of date.
However.
I have seen several recent documentaries on the core of our galaxy. The stars orbiting the massive black hole there are moving so fast around it, you can almost watch them move in the infra-red photos. Lots of dust in that region, so visual telescopes don't see much.
Barnard's Star will eventually come within a fairly short stellar distance of our solar system, then move away from us.
in other words, I have no idea how many miles per hour it is moving. But I hope what I posted this time was useful.
It was interesting. Like I posted above, Traveller, I've come to realize over the last few years, is more a law enforcement and international politics laboratory, therefore threats like super-fast stars swinging by a star system and causing havoc, probably don't fall into Traveller's overall scope of things.
I think someone writing up an adventure about a rogue world careening through a star-system would be, oh, how does one put it, most interesting. From a campaign POV a star moving across a hex may have political implications; say a system moving from pure independence into Swordy or Zho-space. As a matter of the adventurers tackling the physicality of that, I think falls outside the scope of material provided.
Traveller is geared towards the human (or Alien) fallout of cataclysms, usually manmade, and not so much the addressing of astrophysical aberrations.
Still, these are, to my way of thinking, most interesting notions.
