Create a soft, flowing sky using the wet-on-wet technique.
Watercolour paper (A3, 300 gsm)
Soft brush (round or mop)
Clean water
Watercolour paints (deep blue, purple, pink)
Wet the page with clean water until it’s evenly shiny.
Drop in color and watch it spread.
Add others nearby—no mixing, just let them drift.
Let it move. A slight tilt guides the flow.
No fixing—just flow and fade.
Art Meets Science
What you just painted looks like a nebula—a drifting cloud of gas and dust where stars are born. In the Milky Way, these clouds blend into the soft glow we see at night. Light takes 100,000 years to cross the galaxy—so let your colours drift slowly, like space itself.
Shape the galaxy using the wet-on-damp technique. The paper is still damp from before, not soaked, not dry.
A pointed round brush (size 4–6)
Darker paints: deep purple, grey, or black
A sponge or tissue for softening the edges
From the centre, paint a loose spiral—like a whirlpool.
Use gentle, curved strokes. Don’t press hard.
Let the spiral grow outward.
Follow the natural motion of your hand.
Touch the edges with a sponge or tissue.
This softens the arms and fades them into the background.
Art Meets Science
Our solar system lies in one of these spiral arms—not in the bright, crowded centre, nor at the sparse edge, but in the galactic habitable zone, about 28,000 light-years from the centre—where conditions are just right for life.
To paint the centre of the galaxy, we use the lifting technique. We gently take colour away to reveal the light within.
A bit of white or golden yellow paint
A paper towel or soft tissue
Dab a bit of white or golden yellow in the centre.
While it’s damp, gently press a paper towel on top, then lift.
You’ll see a soft glow, like starlight rising from deep space.
Use this technique to brighten other parts of your galaxy.
Try to add a soft light trail to a spiral arm.
Art Meets Science
That soft glow? It’s millions of stars, shining 28,000 years ago. Want to see them now? Check back in 28,000 years—the light’s still on the way. But if 1 galactic year were just 1 Earth year, you’d only have to wait an hour, since it takes 225 million years to go around once—while flying at over 800,000 km/h.
Using the spattering technique, we fill the whole sky with stars.
White paint (watered down slightly so it flicks easily)
A small brush
A toothbrush for fine dots
A test paper to practise on first
Dip your brush in white paint and hold it over the painting.
Use your finger or another brush to gently tap the handle.
Tiny drops will fly off and land where they may.
Practise first on a scrap paper to get the feel for it.
Less water = smaller stars.
For contrast, add a few larger stars by hand.
Art Meets Science
Almost every star you see is part of our galaxy. Our eyes can spot around 3,000 stars, but the Milky Way holds over 100 billion. Try counting them—it would take over 30 years. Once you’re done… good luck learning all their names!
The salt bloom technique creates shimmering textures that look like distant stars and glowing clusters.
A small pinch of table salt
A dry brush to sweep off salt later
A white pen or fine brush
While still damp, sprinkle salt where you want texture.
Along spiral arms, around glows, or in open space.
As it dries, the salt creates natural starburst effects.
Let it dry, then brush off the salt to reveal the texture.
For t final spark, choose a spot to write in white:
“The work of your fingers” or “He calls them by name.”
Art Meets Science
Stars shine because of fusion—tiny atoms are squeezed so hard, they join and release energy as light. Sprinkling salt pulls paint outward, like light bursting from a star’s core.
