Sky at the glance

The essential guide to astronomy
This Week’s Sky At a Glance – Sky & Telescope
  1. Bright Capella high overhead, and equally bright Rigel in Orion's foot, have almost the same right ascension. This means they cross your sky’s meridian at almost exactly the same time. So whenever Capella passes the zenith, Rigel marks true south, and vice versa. That happens around 9 or 10 p.m. now.

  2. Twilight challenge: the planet-conjunction finale! Jupiter and Saturn are becoming ever harder to pick up low in bright twilight, but bring those binoculars on Saturday Jan. 9th. Because then they'll be three! Mercury is emerging to join them. It will pass by them for a couple more days.

  3. As Jupiter and Saturn continue to draw apart, they're sinking ever lower in the southwest in twilight. How much longer can you keep them in view?

  4. Jupiter and Saturn remain close together low in the southwest in twilight, though they're widening every day. They'll sink away into the sunset after New Year's.

  5. This is the week of Jupiter and Saturn's super-close conjunction, and the whole world will be watching. Their separation narrows each evening until December 21st, then re-widens.
