NASA’s Hubble Space Telescope revealed that
a jet of material ejected from a supermassive black hole
triggers star eruptions along its path.

2
00:00:14,781 --> 00:00:22,689
The jet was found at the center of galaxy M87.

3
00:00:22,689 --> 00:00:35,535
These erupting stars aren’t caught
inside the jet, but are dangerously nearby. 

4
00:00:35,535 --> 00:00:45,745
In double-star systems, an aging, swelled-up star 
spills hydrogen onto a white dwarf companion. 

5
00:00:45,745 --> 00:00:54,788
A white dwarf is a low-mass star that
has exhausted all its central nuclear fuel.

6
00:00:54,788 --> 00:01:07,067
When the white dwarf gathers enough hydrogen
it erupts into space, in an event called a nova.

7
00:01:07,067 --> 00:01:12,872
The white dwarf isn’t 
destroyed by the nova eruption…

8
00:01:12,872 --> 00:01:22,582
…instead, it resumes siphoning fuel from its companion,
restarting the nova-outburst cycle.

9
00:01:22,582 --> 00:01:32,025
Hubble observed twice as many novae near
the jet compared to other parts of the galaxy.

10
00:01:32,025 --> 00:01:44,671
The jet is launched by a 6.5-billion-solar-mass black hole.

11
00:01:44,671 --> 00:01:56,549
Engorged with infalling matter, the black hole shoots
a 3,300-light-year-long plasma jet through space at nearly light speed. 

12
00:01:56,549 --> 00:02:10,196
The jet may be pushing hydrogen fuel onto white dwarfs, 
causing more frequent eruptions.

13
00:02:10,196 --> 00:02:19,272
It’s also possible that the jet is 
heating the dwarf's companion star…

14
00:02:19,272 --> 00:02:30,049
…leading it to overflow and deposit 
more hydrogen onto the white dwarf.

15
00:02:30,049 --> 00:02:40,994
After more than 30 years of discoveries…

16
00:02:40,994 --> 00:02:50,837
…the Hubble Space Telescope continues to 
uncover new mysteries that surprise astronomers.
