Legend has it that 3000 years ago two Chinese astronomers were executed because they failed to predict a lunar eclipse.
Fortunately, a partial lunar eclipse today was forecast centuries in advance. At 8.16pm Earth's shadow will start to take a circular bite out of the full moon, and for an hour this bite will grow until more than half of the moon's surface is darkened. The moon will then begin to escape from behind the Earth, and by 11pm the entire full moon will again be visible. Read more
There will be an unprecented double eclipse in the next week. A partial eclipse of the moon occurs on Saturday night - with an even more spectacular phenomonen happening at midnight next Wednesday. The heavenly happening as the Earth's shadow creeps across the moon will be visible everywhere and will begin at 8.16pm on Saturday, June 26. The Sydney Observatory is offering people with digital cameras and phones the chance to take photos through its telescopes. Read more
Today is the longest day of the year, the June solstice, which marks the beginning of summer in the Northern Hemisphere. At 4:29 a.m., the Earth's Northern Hemisphere tilted toward the sun at a 23.5-degree angle, placing the sun directly over the Tropic of Cancer, the northernmost latitude to be hit by direct rays. The U.S. Naval Observatory estimates that the sun will rise at 5:36 a.m. and set at 8 p.m. today in Palm Springs. Read more
Venus appears so dazzling that it's now capturing the gaze of countless millions soon after sunset, and this week for those situated north of the equator it will appear to stand higher in the western twilight sky than at any other time this year. Read more
Venus appears so dazzling that it's now capturing the gaze of countless millions soon after sunset, and this week for those situated north of the equator it will appear to stand higher in the western twilight sky than at any other time this year. Weather permitting, this brilliant lantern-like planet will shine more than 25 degrees high at sunset and still about 15 degrees above the horizon as the last bit of twilight glow fades. For comparison, your fist held at arm's length covers roughly 10 degrees of the night sky. Read more
