HUBBLE OBSERVES
FLAPPING SHADOW IN SPACE

2
00:00:08,340 --> 00:00:22,469
The Hubble Space Telescope has recently 
observed something fascinating happening in space.

3
00:00:22,469 --> 00:00:36,557
A planet-forming disk around a young star 
named HBC 672 is casting a huge shadow 
resembling a pair of flapping wings.

4
00:00:36,557 --> 00:00:43,063
Hubble captured one image of 
this giant shadow in 2017...

5
00:00:43,063 --> 00:00:55,105
...but when Hubble looked at it again later, 
scientists realized that the shadow had moved.

6
00:00:55,105 --> 00:01:08,692
When you compare the images back to back, 
the giant “wings” appear to flap.

7
00:01:08,692 --> 00:01:20,694
A planet’s gravity could be warping the disk
into the shape of a saddle,
causing the shadow to change as the disk rotates.

8
00:01:20,694 --> 00:01:36,572
With 30 years of observations, Hubble can
watch celestial objects change over time
to better understand how the universe works.
