The Observatory Desk · Live Sky

The living almanac.

This page reads the real sky the moment you open it. The Moon below is drawn to its true phase right now; its sign, the Sun's sign, and the next new and full moons are all computed from live astronomy — not written in advance. Come back and it will have moved.

Plate · The Coming Lunations

The next new and full moons.

Plate · The Year in Falling Stars

Meteor showers.

The great annual showers, each the dust of a comet or asteroid the Earth passes through. Peak dates shift a day or so year to year.

Marked in cyan: the next shower to peak from today. Rates are meteors per hour at the peak under dark skies.

Plate · The Backward Walk

What a retrograde really is.

No planet ever actually reverses. A few times a year, a planet appears to slow, stop, and drift backward against the stars for weeks — then loop forward again. It is an illusion of perspective: the Earth, on a faster inner track, overtakes a slower outer planet, and for a while that planet seems to fall behind, the way a slower car looks to slide backward as you pass it. The loop it traces is real to the eye but not to the orbit.

Astrology reads these windows — Mercury retrograde most famously — as times to review, revisit, and slow down rather than launch. Whatever you make of that, the motion above is exactly what the sky does. Mercury and Venus loop for a slightly different reason — they overtake us on the inside track — which Mercury retrograde, explained twice shows with a live model; Today's Sky lists which planets are retrograde on any date.

Moon phase, Moon sign, Sun sign, and the coming lunations are computed live from standard astronomical formulae, accurate to about a degree. Astrarium is a lens for reflection — never medical, financial, or legal advice.
