Sky Watch

I'm a naked eye astronomer, as were all astronomers before the invention of the telescope, four centuries ago. I love to watch the sky at night, observing the slow dance of the planets amongst the stars.

Today we get only a dim glimpse of what earlier peoples must have seen in skies unfettered by dust pollution and, in urban areas, the light pollution that bleaches out all but the moon and brightest stars.

Here are some things you can see in the night sky as the never-repeating, never-ending, cosmic dance continues.

Planet Positions:

Mercury is usually hard to see because its stays close to the sun. Its orbits the sun once every 88 days, and so alternates between evening sky and morning sky approximately every 6 weeks. Next evening appearance, late-March/early-April. On Apr 3 it is just below and to right of Venus .

Venus Venus has reappeared in the evening sky and throughout the summer will perform one of her illustrious dances.. As she rises higher in he evening sky, Mars and Saturn approach from the East, all three meeting in August.

Mars Mars is high in the night sky (February), Through the summer she will move across towards Venus, followed by Saturn, the three meeting in early August.

Jupiter, is in the morning sky

Saturn will be in the late evening sky by March, drawing closer to Mars, and meeting Venus for a beautiful triple conjunction around Aug 7.

The Ecliptic
For spotting planets, and following their motion, it is helpful to know where the ecliptic is. The ecliptic is the imaginary line stretching across the sky, along which the sun, moon and planets all appear to move. If, for example, the sun has just set, and the moon is up high, then the ecliptic is the line from the sun (somewhere just over the horizon) through the moon and beyond to the opposite horizon. The planets will also be not far from that line. Or, if you can see two planets, but no moon, the line through the two planets defines the ecliptic. It doesn't take long to get to know where the ecliptic lies, and roughly where to look for planets.

The twelve Zodiacal constellations (Taurus, Pisces, Gemini, etc.) also lie on the ecliptic -- they are the constellations the planets pass through.
