How to Draw a Black Hole

1. Begin by drawing a half circle. Notice that the line segmenting it is curved, not straight. This is the event horizon - the point where gravity becomes so strong that nothing can escape.

Then, draw a curved line alongside the black hole and extend above it. This indicates the relativistic jet - a blast of particles and radiation from the poles of the black hole.

2. Use a long curved line to draw the opposite side of the relativistic jet. Then, use curved lines that meet at sharp points to begin sketching the round, spiraling accretion disk around the black hole.

3. Continue sketching the accretion disk, using curved lines that meet at sharp points to draw the spiral shapes.

4. Draw more spiral arms of the accretion disk, again using curved lines that meet at sharp points.

5. Draw another spiraling arm of the accretion disk using curved lines that meet at a point.

6. Use curved lines to create long, double-pointed shapes at the edges of the accretion disk.

7. Draw more pointed shapes at the edges of the accretion disk. Then, from below the disk, use long curved lines to sketch the relativistic jet at the opposite pole.

8. Draw small four-pointed stars in the background.

9. Draw many more four-pointed stars in the background. Notice that these are smaller than the first.

Your black hole drawing is now complete. Color the phenomenon and the space around it. We've shaded the gas and dust of the accretion disk in orange and purple. The center of the black hole - the event horizon - is black as its name suggests, since even light cannot escape.
