His only company on board the station are stern mission chief Minkowski, insane science officer Hilbert, and Hephaestus Station's . [34] No excess infrared emission has been detected, which may indicate the lack of a debris disk in orbit around it. It would take a spaceship 7.86 years travelling at the speed of light to get there. parallax. If the value is positive, it is north of the celestial equator. It's been speculated that the Wolf 359 survivor is the Endeavour based on Janeway reading the Captain's Log of her captain in Scorpion where he discussed the Borg encounter. The Hubble Space Telescope was recently used to search for faint companions about Wolf 359. However, that hasn't kept astronomers from studying it. The resulting chemical compounds survive long enough to be observed through their spectral lines. ga('ads.send', { Was there some reason that they waited before proceeding on?
