The winter evening sky was dominated by two exceptionally bright “stars” that are actually planets — resplendent Venus, nearest of planetary neighbors, in the west, and regal Jupiter, largest of the planets, in the east. As we enter spring, Venus and Jupiter remain celestial highlights, and will treat us to a special double-feature in mid-April — each planet will be very close to a prominent open star cluster.
If you rise early on Saturday, April 4 you will be treated to an unusual event: the third of four total lunar eclipses occurring within a period of just two years. This has been called a lunar eclipse tetrad.
The December solstice is coming! At 4:03 p.m. Mountain Standard Time on December 21st, the Sun reaches its most distant point south in 2014, as viewed from Earth. This defines the December solstice, which is the shortest day in the Northern Hemisphere and the longest day in the Southern Hemisphere.
On these late October evenings, you may see a hazy band of light stretching from the southwestern horizon and crossing overhead to the northeast. This is the Milky Way, an object of great wonder throughout human existence.
Next time you see the Big Dipper out of the corner of your eye, take a look at the star in the middle of the handle. If you have decent eyesight, you may see not one, but two stars: a brighter star known as Mizar, and a fainter star called Alcor.
"BORING!" said the 5-year-old of the little blue dot appearing through the telescope…
Perhaps at first glance, but considering that Neptune, the 8th planet, is 30 times farther from the Sun than Earth, it’s actually an amazing sight. At approximately 2.8 billion miles away, it cannot be observed with the un-aided eye. Seeing the disk and color requires a moderately sized telescope, and a keen-eyed astronomy buff.
We learn in grade school that the Moon, our nearest neighbor in space, causes tides on the Earth’s oceans. It does so through its gravitational attraction to the Earth. But the gravitation interplay between Earth and Moon has other, subtler effects as well.
The Sun sets late on these long summer days, and it’s not fully dark until almost 10 PM. And, because of this week’s late-rising moon, the sky remains dark long after twilight, allowing us great views of the Milky Way and the stars of summer.
With the arrival of warmer temperatures, perhaps you’ve been enjoying some outings to the mountains or a float trip on a river. While there is no doubt that summer is in full swing here in western Colorado, it’s not until this coming Saturday that the Universe makes it official.
