The night, hour by hour
The sky over Houston from sunset to sunrise, on the town's own clock: the band shades from twilight to full dark and back, and each bar is when the Moon or a planet is above the horizon, drawn bright while it can be seen. The dot is the best moment to look.
Planets tonight
Where and when to look for each planet from Houston. A planet counts as visible when it is at least 5° up once civil twilight is over; Uranus and Neptune need 10° and a darker sky, and binoculars or a telescope.

ISS passes over Houston
The International Space Station crosses the sky as a bright, steady point, faster than a plane and without blinking lights. These are its visible passes over Houston in the next five days, worked out in your browser from its latest orbit.

The aurora from Houston
Houston is too far from the auroral oval to see the northern lights: on NOAA's rule of thumb even the strongest storm on its scale, Kp 9, leaves it below the northern horizon. NOAA calls the rule approximate, and the rarest storms have reached further, but from here the aurora is a once-in-a-generation sight.
The live forecast and the best time to look are on northern lights tonight.
The next two weeks
Each night's sunset, its fully dark hours and the Moon. The last column is the darkness with the Moon down, the time for faint stars and the Milky Way; the best nights are marked.
