Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our
fascinating universe is featured, along with a brief explanation
written by a professional astronomer.
2025 December 3
The illustration shows a structured orange band stretching horizontally
across the imager. Connected in the middle is the Milky Way Galaxy
curving up to the top of the frame. A second image of the orange band
runs like a sine wave across the lower half of the frame, while a
second image of the Milky Way galaxy appears just above it. Please see
the explanation for more detailed information.
Visualization: Near a Black Hole and Disk

Explanation: What would it look like to plunge into a monster black
hole? This image from a supercomputer visualization shows the entire
sky as seen from a simulated camera plunging toward a
4-million-solar-mass black hole, similar to the one at the center of
our galaxy. The camera lies about 16 million kilometers from the black
holeCÇÖs event horizon and is moving inward at 62% the speed of light.
Thanks to gravityCÇÖs funhouse effects, the starry band of the Milky Way
appears both as a compact loop at the top of this view and as a
secondary image stretching across the bottom. Move the cursor over the
image for additional explanations. Visualizations like this allow
astronomers to explore black holes in ways not otherwise possible.
