In the sky
A telescope is needed to see it: its apparent magnitude is 14.33. Visible from the whole Southern Hemisphere and north to latitude 51° N. South of latitude 51° S it never sets. It stands highest at midnight in July, the best time to observe it.

Light's journey
The light you see tonight set out around the year 326. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 30 million years.
The Sun seen from there
From a planet around NGTS-25, the Sun would look like a star of magnitude 13.42, in the direction where our sky has the constellation Lynx. It would be invisible to the naked eye.
