Stellarium – Find the Humanity Star

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

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

Here is a quick tutorial on how to find the Humanity Star 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.

Tutorial – use Stellarium to find the Humanity Star satellite

First, you have to use the satellite database which is available in the Configurations > Plugins section of Stellarium.

Click on the wrench with the star, then click the Plugins tab, then scroll down until you see “Satellites” in the list on the left.

Update the satellite data

Once you have done that (be sure to check “Load at startup” you will have a list of satellites to choose from. However, there are new objects launched into space every day, so this plugin has a button that says “Update Now”

Stellarium can hep you find the Humanity Star
Update the satellite list to get all the newest satellites – including the Humanity Star.

Search for the Humanity Star

Now, open the Search panel in Stellarium and type Humanity Star and hit the return key on the keyboard or click the magnifying glass button.

Open the Search panel and type Humanity Star. Stellarium will find it.

Stellarium will highlight the Humanity Star. Hit the space bar to lock it into the view.

Time lapse

Now that Stellarium has locked the Humanity Star into the view center. You can speed up time by tapping the “L” key on the keyboard a few times. This will speed up the clock and show you where the Humanity Star is traveling in the sky.

Predicting the brightness (magnitude) of the Humanity Star

By using this website, you can enter your location on Earth (in the top right of the page choose Location) and track many satellites and get predictions for when they will fly overhead.

The Humanity Star is one of several “satellites of special interest” so you can click on the link and see flyover predictions with magnitude estimates.

According to the satellite tracking website “Heavens Above” the Humanity Star is not one of the brightest objects in the sky. In the second week of March 2018, it ranges from magnitude 4.1 to 8.4. Magnitude 4.1 is just barely visible to the naked eye in light polluted suburban skies, but magnitude 8.4 is basically invisible under all normal viewing conditions.

This table shows the visibility and brightness prediction for the Humanity Star satellite

I would love to hear if you were able to use these directions to find and see the Humanity Star in your area!

Clear Skies. Happy Humanity Star satellite hunting with Stellarium.

Quiz – Can we see the Sun at midnight? Where is it?

Can we see the Sun at midnight?

Yes. We can see the Sun at midnight. But, only if we are at one of the polar regions during the Summer season.

Image of the Sun's rays hitting the Earth. The Earth is tilted 23.4 degrees. Summer is when the northern hemisphere is titled toward the Sun. The summer Sun never sets - not even at midnight - if you are north of the Arctic Circle.
You can see the Sun at midnight! If you are at the North Pole in summer.

A quiz – seeing the Sun at midnight – don’t scroll til you try to answer!

When you see the Sun “rising” in the morning at dawn you are facing the east.

When you see the Sun “setting” at the end of the day you are facing the west.

Assuming you are not above the Arctic circle and not too close to the equator… if you could look right at the Sun (when the night is exactly half over) – by looking through the Earth – which cardinal direction would you be facing? East, West, North, or South?

Looking north or south to see the Sun at midnight?

Answer and Explanation

This quiz tests an observer’s ability to think about cardinal directions at the same time paying attention to meridian, time, and hemispherical location.

When we see the Sun “rising” in the morning at dawn we are facing the east.

When we see the Sun “setting” at the end of the day we are facing the west.

When we look at the Sun at noon in the northern hemisphere we are facing south.

SPOILER ALERT — And when we look at the Sun – as if the Earth were transparent – at midnight in the northern hemisphere we are facing north.

In the southern hemisphere sunrise and sunset appear in the same cardinal directions (East and West). But as we pretend that we can look through the Earth at the Sun… at midnight… we are facing south. See the diagram below.

Image of 2 stick figures on the the earth - one in the northern hemisphere, one in the southern hemisphere - looking through the Earth to ward the Sun at midnight
Observers in the northern hemisphere face North at midnight to “see” the Sun. Those in the southern hemisphere face south.

I welcome any and all observation and feedback on this quiz!

Physical Astronomy – Definition of a New Way of Teaching

Definition of Physical Astronomy

Physical astronomy definition using Leonardo DaVinci's Vitruvian Man drawing surrounded by moon phase images
Vitruvian Man with Moon Phases

Physical Astronomy is a new way of teaching astronomy that emphasizes the human body and its relationship to other moving objects in space. The goal is to bring geometric and scientific awareness to a child’s everyday sky observations. Kids learn easily visible sky motions at a “kid’s eye level.”

The Sun does not move… we move

One of the first steps in Physical Astronomy is to forget you ever heard the words “Sunset” or “Sunrise.”  These words (while rife with history, beautiful in their own right, and descriptive) are scientifically wrong. These words obscure the truth of our trip around the Sun. We are on the Earth, the Earth is spinning; the Sun appears to be moving, but it is us moving. 

From the outset Physical Astronomy challenges you to reconsider long-held perceptions. It challenges you to trade them for curiosity, scientific thinking, and observation.

Foundations of Physical Astronomy

Physical Astronomy means learning basic astronomy concepts with a Kinesthetic approach: your body is on the Earth but traveling in space. While we are actually traveling in many directions at the same time the daily perception of our direction is of traveling “under the sun.” Through imagination and knowledge, you can see your place within the motions of the Earth, Sun, Moon, stars, and galaxies.

Science and the Scientific Method are the foundations of Physical Astronomy. Teaching methods, tools, and models scale Astronomy concepts to human size. Imagination transports us beyond our current understanding.

The Future of Physical Astronomy

I would like each child to get a little bit closer to understanding advanced but fundamental physical concepts like light speed, orbits, phases, star distance. The goal is to offer very early involvement with physics and motion. This early exposure to the idea of the speed of light can give a future adult a natural base of understanding.

For most of human existence we earthlings did not know that we lived on the surface of a giant sphere. My goal with this new way of teaching astronomy is to bring curious young minds fun, high-quality, experiential, developmentally tuned lessons for getting involved in the process of scientific discovery.

My intent is to build a strong and scientifically accurate conceptual foundation in a child’s mind. This will bring a passionate and articulate dedication to astronomy specifically, and science in general.

The next Halley, Herschel, Hubble, Einstein, or Hawking.

I have always been captivated by the sky. And I’ve come to realize that even though everyone has some knowledge of what’s “up there” (no matter how much absolute knowledge someone possesses) they always want to know more. The study of the sky is endless! There are so many ways to bring that sense of depth to more and more kids. Let’s continue so that we nurture the development of our next Halley, Herschel, Hubble, Einstein, or Hawking.

I have a big goal with my Physical Astronomy education programs: to encourage people to see the world from a new perspective and to transform them.

We do this by offering repeatable experiences – personal science experiences – that shape the way we perceive our particular place in the universe.

See Mercury and Venus orbits during the day

Your hands and arms help you see the orbits of Mercury and Venus and the shape of solar system

Question: If you could see the orbit of Venus would it fill the whole sky?

The answer might surprise you!

You can use your hands and arms to see the size of the orbits of the solar system’s inner planets: Mercury and Venus.

Imagine (as pictured below) if the orbit of Mercury were visible as a red oval and the orbit of Venus were visible in green.

Use your hands and elbows to see Mercury and Venus orbits any time of day or night. The orbits of Mercury and Venus can be seen.
Two hand spans show Mercury’s orbit, elbows show Venus’s orbit.

Physical Astronomy – see Mercury and Venus orbits

Caution! Do not look directly at the Sun without proper solar safety glasses on.

Turn toward the Sun, hold your arms out straight, hands up in the air with fingers spread wide and thumbs touching. Your pinky fingers now span the width of the orbit of Mercury and your elbows span the width of the orbit of Venus.

Both of the entire orbits of Mercury and Venus orbits would be visible in the sky all at once – if they could be made visible during the day.

Shapes with Shadows – astrosketching Moon features with Alex Massey

Shapes with Shadows – what they can tell us

This the first of two special guest posts by Australian astrosketch artist Alexander Massey 

Live View Sketch of Moon craters Azrachel, Alphonsus, and Ptolemaeus by Alex Massey

Ptolemaeus, Alphonsus, and Arzachel… the names of three massive, interlocking craters on the Moon. These three craters tell the story of the ancient Moon’s creation and evolution. It’s a story of violent bombardments and oceans of lava. We can use light and shadows to reveal the shapes and deep history of these features.

Most people think of astronomy a science of light. But, light creates shadows when it hits things. Those features that lie in the shadows, the dark parts and seemingly just-in-the-way-of-the-light parts, are just as important as those that shine brightly. These dark shadows form most of the mass of all galaxies, house stellar nurseries, reveal old lava rivers on the Moon, and create curious plays of light and dark. These can play tricks on our eyes and make patterns appear.

Galaxy Rise

Physical Astronomy by Daniel Cummings

A still more glorious dawn awaits Not a sunrise, but a galaxy rise A morning filled with 400 billion suns The rising of the milky way.

The Sun rises. The Moon rises. Stars rise. The Galaxy rises – twice.

Each day the Earth rotates and sky objects (seem to) rise in the Eastern sky. The Sun, the Moon, the Stars, and the Galaxy rise at various times.

The Sun “rises” once-a-day at the start of the day.

The Moon “rises” once-a-day at different times of the day and night depending on the moon’s orbit around the Earth (its phase).

The Stars “rise” once-a-day – all night long, one after another and in groups.

The Milky Way Galaxy “rises” twice a day – once on its bright (center) side and then 12 hours later on its dim (outer arm) side.

We can orient our bodies to the rising of the Milky Way. And we can experience our daily movement as “plunging through” this flat disk of stars.

Mistakable rises toward the zenith as you walk toward the equator
As you walk toward the equator, Mintaka appears to rise higher in the sky.

In this post we will learn how to use one bright star of Orion’s belt to visualize the Earth’s equator.

Mintaka is a Star in Orion’s Belt

When you look up at the winter sky in the northern hemisphere, Orion and his famous belt are impossible to miss. The belt is made up of three stars of equal brightness.

One of these stars is called Mintaka and it is a guidepost for finding the Earth’s equator in space. Continue reading “Walk to Mintaka”

Tilt Head to Tilt Earth

Physical Astronomy by Daniel CummingsTilt your head to tilt the earth and experi nice the seasons

Seasons are caused by a tilted Earth

Use this technique to understand how seasons happen on the Earth. The Earth is tilted. When the northern part (your forehead and eyes) tilts away from the Sun the season is winter. When the northern part tilts toward the Sun the season is summer.

The Earth is tilted as it spins daily – it is not straight up and down like a top, but more like the Leaning Tower of Pisa (if the tower could spin!). As it goes through its yearly orbit, the Sun hits the northern and then the southern parts of the Earth.

Tilt your head to tilt the Earth

In this model, when the northern part (your forehead and eyes) tilts away from the Sun the season is winter. When the northern part tilts toward the Sun the season is summer.

The Moon is Upside Down

When you are in the southern hemisphere, the moon looks upside down.

When I came back to the US from living in Australia for 4 years, I published a poster with a picture of the moon on in and I placed it “upside down” – someone pointed it out and I looked at the moon and said “the moon is upside down.” This was true – in the Northern Hemisphere – but to people living in the Southern Hemisphere the moon appears “upside down.”

I was shocked, but the claim was true – in the Northern Hemisphere! But to Australians and other people living in places in the Southern Hemisphere the moon appears “upside down.”
