What's happening in space, and what can you see in the sky tonight? Space news, a stargazing forecast for your city, the space photo of the day, launch countdowns and alerts, a Missions board and a sky calendar.

SPACE NEWS
The latest from NASA, ESA and the space press, by topic: discoveries, the night sky, launches, astronauts, the Moon, Mars, exoplanets, the solar system, telescopes, space weather, the cosmos, asteroids, life beyond Earth and more. Follow over 50 agencies, companies, missions and worlds, with a notification at most once a day for each, never at night.

TONIGHT
Pick your city and see if tonight is good for stargazing: clouds hour by hour, when it gets dark, the Moon, which planets are up and where to look, and the aurora chance, with an optional aurora alert.

SPACE PHOTO OF THE DAY
A new picture every day from NASA, Webb, Hubble and the European Southern Observatory, with the story behind it.

LAUNCHES
Every launch worldwide with a countdown, the webcast and reminders. Alerts for every launch or only the big ones: crewed flights, science missions and new rockets.

MISSIONS
Where the major probes, rovers and telescopes are, what they're doing, what comes next, and their latest headlines.

SKY CALENDAR
Meteor showers, eclipses, full moons and supermoons, planets at their best, close pairings, equinoxes, and big launches and mission milestones, in your time zone, with reminders.

LEARN
A space fact a day, and over 130 space words explained, also tappable in the news.

NOT A GOVERNMENT APP
Astronomy & Space News is an independent app. It is not made by, affiliated with or endorsed by NASA, ESA, NOAA, ESO, the United Nations or any government or space agency. Information from those agencies comes from their official sources, listed below.

WHAT IT CAN'T DO
Launch times often change. Cloud forecasts can be wrong; an aurora is never guaranteed. Mission dates are the agencies' plans. The news is written by the publishers it links to, not by us.
