The Global Positioning System (GPS) is precise.

That precision originates in a mind-blowing place!

GPS signals tell billions of people where they are each day.

GPS helps pilots land planes and captains steer ships.

GPS signals stamp locations onto millions of photos.

GPS gives you driving directions.

But, where does GPS get its own GPS?

Stellarium – Find the Humanity Star

A new satellite called the Humanity Star looks like a disco ball

Update Apr. 1, 2018.

The Humanity Star is no longer an active satellite – it has fallen out of the sky: https://www.theverge.com/2018/3/22/17144208/rocket-lab-humanity-star-satellite-new-zealand-astronomy

However, even though the Humanity Star is now gone, this article still teaches you how to load satellites into Stellarium. So, read on for a quick tutorial on how to track any satellite in Stellarium.

Looking for information on how to track the Humanity Star any satellite location using Stellarium astronomy software?

Here is a quick tutorial on how to find the Humanity Star any satellite using Stellarium.

You can track the position of the Humanity Star with Stellarium
The Humanity Star satellite before launch – still on the Earth.

Rocket Lab founder and CEO Peter Beck announced that the company’s rocket had placed a special satellite in a 90 minute orbit around the Earth.

A lot of people want to see this new “star” in the sky. Stellarium can help you do that.

If you don’t have Stellarium, you can download a copy here. And I have a few tutorials that can help you get started with this amazing piece of software.Click here to continue reading…

Stellarium – a glorious gift to Humanity in software form – gives you super powers. And best of all … It’s FREE!

Superpowers!

Always wanted to know the names of the stars and constellations? You can search, play, pan and zoom, examine, compare and anchor your knowledge.

It’s a cloudy night? No problem. You can see through the clouds! 

Wished that the sky had labels on everything? Stellarium has 10 different label types.

Stop time? Move time by day, by week? Do you want to see what will happen in 2 months? Or look at the sky during the Pharoah’s reign? You can time travel.

You can easily drag and zoom, stop time, go in reverse, make a timelapse, follow the moon through its phases. You have a tool to help you understand the ecliptic and sidereal time and retrograde motion. You can see the great orbital swing of Venus as it circles the Sun.

Ok! I’m convinced by your Stellarium review. What should I do now? What’s my call to action?

Get a copy of Stellarium.

You can download it here.

Stellarium is a free, easy to use, and powerful tool – and best of all (did I mention this already?) it’s FREE and easy to use.

I will write some specific tutorials about my favorite parts of Stellarium in 2017, but for now… go get it and play!

You will be able to see things about sky objects and movements that are impossible to see live. But, once you have seen them with the help of Stellarium, the sky will open up for you – like a gift.
