A new star will appear in the sky in 2022

Binary star merge to form a new star - a star in a starAn amazing thing is about to happen! A Star in a Star will be born.

EDIT (Nov. 19, 2021): It turns out that the underlying observation data had a timing flaw that makes it “unlikely” that the new star will be born in 2022. See this Wikipedia page about the new Star for more information.

You  can witness the birth of a new star in the night sky.  The new Star already has a birthday: 2022!

According to scientists, the new star will form when two stars that are orbiting each other grow so close that they merge into one.

The new star will appear in the constellation Cygnus. You can see the approximate location marked by a red circle in the Stellarium screenshot here:

The image of the two blue stars on the home page of this Star in a Star site shows what scientists think it looks like now. This impressive video shows an artist’s rendering of the star merge.

In the pair, one star is larger than the other so in the end, there will be a new star…  A Star in a Star.

The Moon Dance – Learn Moon Phases

PHYSICAL ASTRONOMY BY DANIEL CUMMINGS

The moon dance helps you learn and understand the phases of the moonLearn the Moon phases by doing an easy dance.

At sunset.

Face the sun.

Point your right hand toward the Sun.

Now point your left hand toward the Sun.

Both hands should be pointing at the sun.

Now, turn a little bit to the left, keeping both hands pointing at the sun.

Swing your left arm out until it is pointing in the opposite direction from the sunset. Bring your hands together again and repeat this swinging motion.

Bring your hands together again and point them both at the sun. This time, instead of swinging, bounce your left hand, leftward, some number of times… (14 is perfect if you can do it) …until it is pointing in the completely opposite direction from the Sun at sunset. Your left hand should now be pointing East.

Was the moon at any one of those 14 hand bounce spots? That is the age of the moon in days.

The Moon Moves Toward the Dawn – a Mnemonic

The moon moves toward the dawn

Memorize this mnemonic: The moon moves toward the dawn. This phrase describes the day-by-day movement of the moon. With this simple phrase, you can understand the phases of the moon. You will actually begin to see the moon’s beautiful orbit traced out in the sky.

Repeat. The moon moves toward the dawn. The moon moves toward the dawn. 

The moon moves toward the dawn.
It rises higher in the dusky sky after each day. It sweeps over the hills.
It circles and rolls. It transits. It leaves the Sun, then chases the Sun.
The moon moves toward the dawn.
Look East! That’s where the moon wants to go.
Once arrived, it crosses the face of the Sun and once again moves toward the dawn.
The moon moves toward the dawn.

Hello world! Welcome to Physical Astronomy.

Daniel Cummings moon phase immersiveWelcome to Star in a Star!

There are many ways to learn about Astronomy and the sky. Some people learn best by reading books or websites. Some learn best by debate and discussion. Some learn by doing.

I like to learn about Astronomy by interacting with people, places, and things. I like to listen to children’s questions and wonder along with them. I like to create immersive real-world experiences – aka “Physical Astronomy” – that help to illuminate the answers – when there are answers – and create tools for thought and imagination.

In posts and pages and links and media I am going to show you how to learn (and teach) Physical Astronomy in this unique way. We will learn about how to foster deep scientific understanding through exercising a sense of place and presence in a space.

Most importantly, I hope to share my passion for Astronomy and share the joy I feel each time someone near me says those epic words of discovery: “Wow – I never knew that before.”

Daniel
