Death Valley National Park
International Dark Sky ParkFrom Death Valley National Park (36.5°N), a Bortle 2 dark-sky site, you can see far more than the ISS and Tiangong — a sky this dark reveals faint satellites like individual Starlinks and the Hubble Space Telescope that are invisible from any city. Best viewing is during twilight, after sunset or before dawn. Tonight’s pass times for Death Valley National Park are shown below.
As of 23 August 2026, the Moon is 78% illuminated (waxing gibbous), making it a poor night for faint objects here — the Moon will wash out most of what this sky can show. The next new moon is 11 September, about 19 days away — that fortnight is the window worth travelling for.
Death Valley National Park is one of the darkest locations in California, USA — a Bortle Class 2 sky that unlocks satellites completely invisible from any city. Live pass times are computed for your exact location here.
Bortle is a 1–9 scale of night-sky darkness: 1 is the darkest (pristine wilderness), 9 is an inner-city sky. The lower the number, the more faint satellites, Starlinks and stars come into view.
What you can see here that you can’t see from the city
A Bortle 2 sky has a naked-eye limiting magnitude of approximately 7.2 — two to three magnitudes deeper than an urban sky, revealing satellites that simply don't exist to city observers.
How this rating was set: the Bortle class is an estimate for the main observing area, calibrated against DarkSky International’s published documentation where the site is certified and regional light-pollution mapping where it is not. It is not a single measured reading — sky quality shifts with your exact position, the moon and how much of your horizon is open. For a reading at your own spot, check lightpollutionmap.info.
| Satellite | Magnitude | From here | Notes |
|---|---|---|---|
| ISS (Zarya) | mag -4.0 | ✓ Visible | City-visible. Magnitude up to −4, dazzling even under street lights. |
| Tiangong (CSS) | mag -2.0 | ✓ Visible | City-visible. Slightly dimmer than the ISS with an orange tint. |
| Hubble (HST) | mag +1.5 | ✓ Visible | Visible here — needs a dark sky. Distinctive blue-white colour. |
| AST BlueBird-6 | mag +1.5 | ✓ Visible | Visible here — as bright as Hubble. Often spotted in pairs. |
| BlueBirds 1–5 | mag +4.0 | ✓ Visible | Visible here under this Bortle 2 sky. A dark-sky exclusive target. |
| Starlink (single) | mag +5.0 | ✓ Visible | Individual Starlinks reachable here with Bortle 2. |
Magnitudes are peak naked-eye brightness. Visibility also depends on elevation angle, phase, and local transparency.
Best conditions at Death Valley National Park
The sky over Death Valley National Park: what your latitude shows
At 36.5°N, Death Valley National Park sits in the Northern Hemisphere, and the shape of the sky follows from that. Polaris sits about 36° above your northern horizon, and any star within 54° of it never sets.
The Milky Way's bright core in Sagittarius stays fairly low — culminating about 25° up toward the south, so a low, unobstructed southern horizon is worth seeking out here. The Magellanic Clouds stay below your horizon entirely — they're a Southern-Hemisphere prize you'd have to travel south to catch. The Southern Cross never properly rises from this latitude. Because the core sits to the south and never climbs high, it's best from late spring through summer (roughly May to August), low over a dark southern horizon.
Tiangong, China's space station, orbits at 41.5° inclination — so at 36° you sit on or inside its ground track and it can ride high, even near overhead, blazing as bright as the brightest stars. The ISS (51.6° inclination) is visible on most clear nights, climbing higher in the sky the closer your timing is to an overhead pass. It's a mid-latitude sky — most of the year's named passes and showpieces are reachable from here with the right timing.
Dark Sky Satellite Spotting — FAQ
How dark is Death Valley National Park?
Death Valley National Park is rated Bortle Class 2 on the nine-point scale — an exceptionally dark rural sky. At this level the limiting magnitude for the naked eye is approximately 7.2, meaning you can see stars and satellites far fainter than in any urban setting.
Can I see satellites from Death Valley National Park?
Yes — and far more than you can from a city. The ISS and Tiangong are visible from everywhere, but Death Valley National Park's Bortle 2 sky unlocks the Hubble Space Telescope, AST's BlueBird satellites, and individual Starlink satellites that are simply invisible against a lit urban sky. Use the live pass times above to plan your session.
What satellites are unique to dark skies at Death Valley National Park?
At Bortle 2, AST's BlueBird satellites become reachable naked-eye targets — something no city observer can achieve. Individual Starlinks in their operational shells are also visible, whereas from a city you only see the bright post-launch trains. Hubble (mag 1.5) is another dark-sky exclusive: easily found here, nearly impossible from suburbs.
What is the best time of year to observe at Death Valley National Park?
October – March offers the best conditions. Northern winter nights are longest, temperatures are cold but skies are crisp and transparent. Avoid June – July when longer twilights reduce the available darkness window. Moon phase matters enormously at dark sky sites — a new moon week during October – March is the prime target.
How do I find Death Valley National Park?
Death Valley National Park is located in California, USA, at 36.48°N, 117.08°W, approximately 200 km from Las Vegas. It holds DarkSky International Dark Sky Park certification, confirming its commitment to preserving natural darkness. Check access conditions and any permits required before visiting, particularly for national parks and protected reserves.
Does Death Valley National Park's hemisphere affect what I can see?
Yes — from the Northern Hemisphere, Polaris and the Big Dipper dominates the overhead sky, and the Milky Way core arches in the southern direction. At Bortle 2, the Milky Way casts a visible shadow and complex dust lanes are clear to the naked eye — the same darkness that reveals faint satellites.
