Here is the first-ever photo of the Earth and moon in a single frame. Voyager 1 took the photo on September 18, 1977, when it was 7.25 million miles (11.66 million kilometers) from Earth. Image Number: P-19891 via NASA/JPL

37 years ago today.

Voyager to Earth: “Hello World!” or more likely “Goodbye World!”

Voyager is still sending us postcards from the edge though.

The Seven Wonders of the Solar System

Some suggestions for a superlative list of solar system wonders.

My list off the top of my head:

1. Saturn’s rings
2. Jupiter’s red spot
3. Mars’ Olympic Mons
4. Io
5. Titan
6. Uranus for being axially contrary
7. Oort cloud

Less Than Three Years to Prepare

SolarEclipsePathAug2017
Path of Total Solar Eclipse August 21, 2017

For once, I live in just about the best spot to observe a total solar eclipse. The center line for the eclipse coming in August 2017 is just a few miles north of where I live.  That being said, the path of the eclipse cuts diagonally across the United States from Oregon to South Carolina.

Update Monday 9/1/2014:  I forgot to include a link to the Astronomy magazine article that will take you to the interactive map shown above:  Make Plans for the 2017 Eclipse with This Great Map. Continue reading “Less Than Three Years to Prepare”

Venus Overtakes Jupiter

I thought I’d use the European racing term more commonly known in the States as ‘passing’ to refer to the progress Venus has made in the predawn sky this past week.

Saturday morning I woke up way too early for a weekend, but remembered reading something about Venus and Jupiter getting closer together.  Without reminding myself by actually looking the information up via Facebook or Twitter or Google, I threw on some clothes, grabbed the keys to one of the vehicles (didn’t care which one) and rushed outside.  It was still very dark, just after five o’clock (Central time zone).  I drove a block up a slight hill to my favorite eastern horizon viewing site (just to the east of Lansing City Hall) and waited … and waited … and waited.  I finally used my smartphone (which I never leave home without) to check when Venus and Jupiter were supposed to rise (using Astronomy.com’s Tonight’s Sky mobile web page).  Continue reading “Venus Overtakes Jupiter”

I wonder how long before Mercury will be added to the list?  Or perhaps the moons of Jupiter and Saturn.

Moon Passes Near Both Mars and Saturn this Week

Yesterday, I saw a post via Sky & Telescope’s Facebook feed that reminded me to get out my telescope. This week, starting tomorrow, you don’t need a telescope to see something amazing.

Saturday after sunset, look to the south to see the Moon near Mars.

Monday, again after sunset, look a bit farther to the south-east to see the Moon near Saturn.

Here’s a link to Sky & Telescope’s article about the Moon juicing up July:

Two Moon-Planet Conjunctions Juice Up July

But back to my telescope. I know I don’t need it to see the above two events, anyone with eyeballs can observe them. I wanted to get out my telescope and shake off the cobwebs. It’s been a cloudy spring this year, at least on the weekends. I observed Mars first, trying to see the polar ice caps, then I switched to Saturn, where I clearly saw the separation between the rings and the different cloud layers. The angle of the rings with respect to Saturn is spectacular right now.
