On Christmas Day 1998, the moon almost occulted the planet Jupiter - always an impressive sight when two of the brighter night-sky objects appear to collide.

Moon and Jupiter on Xmas night. 300mm f5.6 4secs Moon and Jupiter on Xmas night. 300mm f5.6 1sec The shot at left was taken at about 10pm.

The one at right, about an hour later.

Sadly, the moon sunk into the trees soon after this, preventing further photography. Jupiter skimmed by the arc of the moon, missing it by only minutes of a degree.
About 20° further south the occultation was complete - halfway between Hobart and Antarctica!

Both photos were taken through an f5.6 300mm Schmidt-Cassegrainian telephoto lens, on 100ASA colour negative film.
The left hand exposure was 4 seconds, the right hand one about 1 second. The images as presented are in colour!


Moon and Venus... 16/6/99 Same satellite - different planet.
On June 16th, 1999, the moon passed within 2° of Venus. Here is the result, as viewed from the same location with the same equipment as above (except that this time the photo is rendered in black & white.)

Given that the moon is 2° from Venus (in this photo), roughly what angle would you say the moon subtends at Earth; i.e. how wide is the moon in degrees, as viewed from the Earth?

Answer

 

Look what happened to the moon one year and one month later, on July 16th 2000.

Click for eclipse shots Another partial lunar eclipse - October 17, 2005. Not very impressive, but we still captured it here.
Click for eclipse shots Yet another partial lunar eclipse - June 26 2010. No reddening, but a lovely sharp terminator line. Click here.

Click for more Lunar eclipses are fun, but for a gob-smacking overwhelming spectacle, nothing beats a total eclipse of the sun. 4,600 km travelled, many more than that dollars spent, and three weeks away from school (sob!) provided this account of nature's most impressive syzygy.
Click for more We can't beat a total solar eclipse (see above) but this partial solar eclipse on November 24th 2003 will be visible at school, during school time. Come to the eclipse party!

The clouds did their level best to ruin the viewing, but this eclipse broke through just enough for a few good shots. Details here.
Click for more Twelve or thirteen times a century, the planet Mercury passes between the sun and us. If Mercury was w-a-a-a-a-y bigger, we might call this event an eclipse. Instead, it is a transit of Mercury. This one happened on 7 May 2003, and Parramatta high astronomers were on hand to observe it.
Click for more Much less frequent than transits of Mercury (see above) are transits of Venus. Get some background information, then have a look at the photos of the actual event. Next one in eight years, then another 112 years. Be quick.

Click for more September '05, and Jupiter plays chasings with Venus and Spica. A magnificent sight to the naked eye, this photo sadly fails to capture the full effect.
Still worth a look, though.
