00:00:00.000 --> 00:00:05.305
>> HUBBLE’S BRAND NEW VIEW OF
AN INTERSTELLAR COMET

2
00:00:05.305 --> 00:00:15.349
>> The mysterious comet C/2019
Q4, also named 2I/Borisov, comes
from outside our solar system.

3
00:00:15.349 --> 00:00:25.626
>> Comet Borisov is the second
interstellar object sighted in
our neighborhood. The first was 'Oumuamua in 2017.

4
00:00:25.626 --> 00:00:36.136
>> Traveling at about 110,000
mph, this comet will pass
roughly 190 million miles from Earth in December.

5
00:00:36.136 --> 00:00:46.914
>> Its high velocity indicates
it came from interstellar space
and will return there again.

6
00:00:46.914 --> 00:00:56.490
>> On October 12th, 2019,
astronomers used Hubble to get a
detailed look at the speeding comet.

7
00:00:56.490 --> 00:01:06.366
>> Hubble found the comet's properties
Appear to be very similar to those of
our own solar system's building blocks.

8
00:01:06.366 --> 00:01:11.638
>> The comet was discovered by
amateur astronomer Gennady
Borisov in August 2019,

9
00:01:11.638 --> 00:01:16.209
And observers around the
globe can catch a glimpse of
it over the next few months.

10
00:01:16.209 --> 00:01:24.051
>> Astronomers will continue to
observe Comet Borisov until it
leaves our view forever

11
00:01:24.051 --> 00:01:33.126
>> and we’ll learn as much as we
can about this interstellar
visitor.
