Star map of Houston — the night sky over Houston, on your date
Houston sees most of the sky turn over the course of a year. Pick the night that matters and we draw the sky exactly as it stood above Houston — 29.76°N, 95.37°W — at that hour.

What the sky over Houston is actually like
Houston stands at 29.76°N, and latitude is the thing that decides which half of the sky you are allowed to see at all. From here nothing stays up permanently — everything rises and sets. Nothing is completely out of reach from Houston, though the Plough (Ursa Major) and Cassiopeia and the Southern Cross (Crux) only ever clear the horizon in part. That is why the city matters on a star map and is not simply a caption under it.
- Latitude. 29.76°N — a middle latitude — most of the sky comes round across the year
- Rises and sets from here: Orion, Cygnus (the Northern Cross), Scorpius, Gemini.
- Only partly clears the horizon from here: the Plough (Ursa Major), Cassiopeia, the Southern Cross (Crux).
- Darkest it gets in midsummer: a good 6.7 hours of true darkness even on the shortest night
- Passes closest to straight overhead: Gemini — very nearly at the zenith from this latitude
These are computed, not written: the same star positions the card itself is drawn from, evaluated for Houston's latitude. Change the city on your card and the sky really does change.
When the sky over Houston is actually dark
A good 6.7 hours of true darkness even on the shortest night. Astronomical night — the point where the Sun is far enough below the horizon that the faint stars come out — is what decides whether a sky is worth looking at, and it depends entirely on how far from the equator you are. It does not change what goes on your card: the map is computed for the moment you choose whether or not anyone could have stood outside and seen it. It is simply worth knowing about your own city.
Why the date matters as much as the place
Place decides which stars you can ever see; date and time decide where they were standing. The sky over Houston on a January evening is not the sky over Houston in July — the Earth has moved a long way round the Sun in between, and the same constellations rise hours earlier. That is why a star map of a particular night is a keepsake rather than a poster: it is only that sky if the moment is right.

Questions people ask
- Can I get a star map for Houston on any date?
- Yes — any date, any time, anywhere on Earth. Give us the moment and we compute where every visible star actually stood above Houston, the same calculation an observatory runs, pointed backwards.
- Is the sky over Houston really different from other cities?
- Genuinely, yes. Houston sits at 29.76°N, and latitude decides which part of the sky you can ever see. Nothing is completely out of reach from Houston, though the Plough (Ursa Major) and Cassiopeia and the Southern Cross (Crux) only ever clear the horizon in part.
- Do I need the exact time?
- No. If you only remember the evening, use something like 21:00 — the sky over one night barely turns between 20:00 and 22:00 at the scale this prints. If you know the hour, use it.
- What do I actually receive?
- A 3000×4200 print file — a clean 10×14″ print at 300dpi. You print it, so there is no shipping and nothing arrives late.
