Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10 times as massive as our galaxy, the thread could contain some of the Universe’s ‘missing’ matter, addressing a decades-long mystery.
The Canis Major Dwarf Galaxy is only 25,000 ly from Earth. Assuming constant acceleration, and sufficient technology to protect and keep things running for all that time - no mean feat - reaching a substantial percentage of light should make that reachable within a hundred or so thousand light years, even with a flip and slow-down halfway.
Seque 1 is only 75k ly.
Andromeda is much farther; I didn’t catch it in the article, but I got the impression the strands were identified between the more local clusters.
…satellite galaxies != galaxy clusters; andromedia is 2.5 million light-years distant and the cluster in this study is about ten times that size, 23 million light-years across…
