Stellarium Web maps stars, planets, constellations, and deep-sky objects across a realistic, searchable night sky.
What is Stellarium Web?
Stellarium Web brings the essential experience of planetarium software into a link. Set a location and time, then pan across an accurately positioned sky. Labels, constellation art, atmosphere, landscape, and object details can be adjusted without hiding the central view. It works equally well for identifying tonight's bright point, planning a viewing session, or simply moving time forward to watch the sky rotate.
Why we picked it
It connects an enormous astronomical dataset to an immediate personal question: what is above me right now? The interface balances beauty with real utility.
How to get the most from it
Allow location or enter a nearby city, set the current time, and search for the Moon or a visible planet. Turn off the atmosphere to see objects below the horizon or during daylight.
Good to know
Location is optional and can be entered manually. Use observations and official local guidance for safety around eclipses or solar viewing.
