A UFO? A Plane? What is It?

It’s Not Planet X, That’s for Sure

Astronomers and planetarium folk have been getting the usual phone calls about “something bright in the West” after sunset.  It’s true. There is something bright out there… but it’s disappearing fast.  It’s the planet Venus, and it’s sinking lower into the western sky each day, and brightens up the post-sunset sky like a jewel hanging there against the dusk.

I love going out to look at Venus. It’s really quite beautiful, and it’s easy to understand why some early observers would call it a goddess. It just gleams in the sky.

Venus looks bright because it’s a cloud-covered world, and those clouds reflect sunlight. Also, it’s a bit closer to us in its orbit right now, and thus appears bigger and brighter.

Venus has a long history in science fiction of being a swamp world or a desert world.  I remember reading some early science fiction where people from Earth were eking out a living among dinosaur-type creatures.  Another book in my library, written in the late 50s, had Earthlings settling on a dry and dusty cloud-covered Venus, and ultimately launching attacks on Earth.

Those stories were WAY off the mark however. In the 1960s, we sent our first probes to Venus, and right away discovered the truth: a world with a poisonous atmosphere that is so heavy it destroyed the probes that landed on the planet. Later on, orbiters such as the Magellan mission mapped the volcanoes of Venus, showing us once and for all that our “sister planet” is not a very hospitable place.

But, or course, you don’t see that when you gaze at the orb of Venus hanging low in the western sky these May nights. That doesn’t make it less lovely to ponder as the sky darkens.   Before too long, Venus will be a morning object, right after it transits the Sun on June 5/6.  So, go check it out. Here’s a map to get you started!

Look for Venus low in the west after sunset for the next few weeks before it disappears in the glare of the Sun.

They’re Up There: You Can’t Miss Them

 

The May night skies, with Saturn and Mars.

 

 

The planets Mars and Saturn are gleaming up there in the sky these May nights.  Saturn is in the constellation Virgo, not far from the bright star Spica. I’ve seen a lot of images people are posting of Saturn, and the rings are standing out. So, if you have a decent pair of binoculars, or even better, a small telescope, you can spot those rings yourself.

When I was a kid, one of the first images of a planet I saw was of Saturn. Those rings absolutely mystified me. They were the most alien thing I could think of “out there” and I often wondered how such things could form. Astronomers knew the rings were made up of particles, but it wasn’t until the Voyager mission to Saturn that they knew just how complex the system really is. And, of course, the Cassini Mission is taking their understanding to new heights.  You can find some gorgeous views of Saturn from Cassini at the mission Web site, and I think they’ll whet your appetite to see the planet for yourself.

Mars is close to the bright star Regulus, in the constellation of Leo the Lion. It’s a reddish-looking blob of light and if you have a fairly powerful backyard telescope, you can make out some of the surface markings (dark and light) on the planet.  Of course, the best way to look at Mars (after you’ve spotted it in your night sky) is to surf over to NASA’s Mars site, or ESA’s Mars Express page.  There, you’ll find many fascinating images of the Red Planet taken by spacecraft visiting the planet “up close and personal”.

Go out these May nights and check out the planets. They’re not hard to find and they’ll pique your curiosity. I guarantee it!
