Stargazing from the airports

How dark it is where the drives end

Every destination on this site, read off NASA's night-light map and sorted into three bands. A band, not a score: the map is a rendered composite, fine enough to tell a lit town from an unlit shore and no finer. The airports themselves sit under their own lights.

Dark — the unlit coast

A town's glow

Inside a town

Source: NASA Black Marble 2016 annual composite (VIIRS) via the GIBS WMS, rendered brightness 0–255 averaged over a ~4 km box centred on the point; a rendered stretch, not a radiance measurement; bands below 12: the unlit coast, 12–60: a town's glow, 60 and up: inside a town. Sampled 2026-09-06. The two airports in that sample read as Gander International Airport: inside a town and Deer Lake Airport: a town's glow.

True darkness by month, at each airport

Hours per night with the sun far enough down for the faint sky — the Milky Way, the dim end of a meteor shower. In June there are none at this latitude: the sky never quite finishes getting dark. It still gets dark enough for the planets, the Moon and the bright stars; the second line is that lesser darkness.

Method: Sun altitude from a standard solar-position formula, sampled every five minutes on the 15th of each month; astronomical darkness is the sun below −18°, nautical below −12°. Cloud, the Moon and the aurora are the other three variables, and they are linked below, not predicted here.

Terra Nova National Park, 78 km from Gander airport straight down the Trans-Canada, is the province’s only Dark-Sky Preserve. It has four officially designated observing sites with paved parking, and two campgrounds where the observing site is your tent.

Check the hours of true darkness for your month in the tables on this page; that decides whether you will see the Milky Way. The drive home is a night drive on moose roads.

Where to go, and how to get there

Before you go

  • True darknessNone in June; the long nights run October to March

    At this latitude the sky never fully darkens around midsummer. The table on this page gives the computed hours of astronomical and nautical darkness by month at the airports it lists. Plan the faint sky for the shoulder seasons and winter; the Moon and the planets for any clear night.

  • CloudEvery night, the deciding variable

    Clear Sky Charts give hour-by-hour cloud, transparency and seeing forecasts for Gander, Deer Lake and Twillingate. Terra Nova has none; Gander's is the nearest. Read the chart before the drive, not the general forecast.

  • The MoonThe week around new Moon, for the faint sky

    A full Moon washes out the Milky Way as surely as a town does. The National Research Council's calculator gives sunrise, sunset and twilight for any place and date; pair it with any lunar calendar.

  • AuroraUnpredictable; check the forecast, not the folklore

    NOAA's Space Weather Prediction Center publishes the aurora forecast and the three-day geomagnetic outlook. We found no source for how often the lights reach this latitude, so trust the forecast on the night.

  • MooseEvery night drive, worst between dusk and dawn

    Stargazing means driving home in the dark. The province says the chance of injury in a moose collision is about twice as high between dusk and dawn as in daytime. Camping avoids the drive. If you do drive, the Trans-Canada through the park is the kind of road the warning is about.

Questions

Which airport is darker?+

Neither, at the airport: both airports sit under their own lights and read as town glow or town on the night-light map. What matters is what is a short drive out. From Gander that is the Dark-Sky Preserve. From Deer Lake the destinations read dark on the map too, but none is designated.

Is Terra Nova the only place to stargaze?+

It is the only designated one — the Royal Astronomical Society of Canada's first Dark-Sky Preserve in the province, February 2018, with a sky quality RASC puts at up to 21.8 magnitudes per square arcsecond. Much of the coast is as unlit; the bands on this page show which destinations the night-light map reads as dark. Designation means somebody measured it and committed to keep it dark. A dark map only means nobody has lit it yet.

What do I need?+

Eyes, a red light, and time for them to adjust. The Visitor Centre lends Night Sky Kits with binoculars, per Parks Canada, and RASC St. John's runs an annual Night Sky Celebration in the park with telescopes; check the park's page for dates. Parks Canada's lighting advice for the preserve applies to visitors too: fewest lights, dimmest, pointed down, off when not needed.

When is the best month?+

For the faint sky, the months with real astronomical darkness in the table: late August onward, and winter for the longest nights. For the planets and the Moon, any clear night. Skip June for the Milky Way; it is the month for a bright sky at midnight.
