1
00:00:00,834 --> 00:00:03,436
The Sun is a star.

2
00:00:03,870 --> 00:00:08,475
It's a star that we often describe
as average, run of the mill,

3
00:00:08,942 --> 00:00:10,477
just ordinary.

4
00:00:10,677 --> 00:00:13,813
Yet this ordinary star is responsible

5
00:00:13,813 --> 00:00:16,816
for helping to sustain all life on Earth.

6
00:00:17,083 --> 00:00:20,920
No other star that we know of
has that level of responsibility,

7
00:00:21,121 --> 00:00:24,124
and that's pretty extraordinary
if you ask me.

8
00:00:24,524 --> 00:00:27,427
The Sun is a living, breathing star.

9
00:00:27,427 --> 00:00:30,563
It is active, dynamic and ever-changing

10
00:00:30,563 --> 00:00:32,065
just like us.

11
00:00:32,332 --> 00:00:35,935
Its influence can be felt
in every aspect of society

12
00:00:36,136 --> 00:00:39,906
from agriculture and economics,
to arts and culture,

13
00:00:40,273 --> 00:00:45,078
as well as the physical, mental
and emotional health of human beings.

14
00:00:45,678 --> 00:00:48,681
The Sun touches everything.

15
00:00:48,815 --> 00:00:52,018
And to highlight the importance
of our extraordinarily

16
00:00:52,018 --> 00:00:57,690
ordinary star, NASA is hosting
the Heliophysics Big Year.

17
00:00:57,891 --> 00:01:01,961
Beginning with the annular
solar eclipse in October of 2023,

18
00:01:02,128 --> 00:01:06,399
continuing with a total solar
eclipse in April of 2024,

19
00:01:06,566 --> 00:01:09,736
and ending with Parker
Solar Probe’s closest approach

20
00:01:09,736 --> 00:01:12,739
to the Sun in December of 2024,

21
00:01:12,906 --> 00:01:17,177
the Heliophysics Big Year is a global
celebration of solar science

22
00:01:17,377 --> 00:01:19,879
and the Sun's influence on
everything. 

23
00:01:20,280 --> 00:01:23,316
Over the course of the year we are
challenging everyone -

24
00:01:23,316 --> 00:01:25,885
including the public, the science
community,

25
00:01:25,885 --> 00:01:31,024
and you - to participate in as many
Sun-related activities as possible.

26
00:01:31,958 --> 00:01:34,360
Heliophysics is the study of the Sun

27
00:01:34,360 --> 00:01:37,363
and its influence on, well, everything.

28
00:01:37,630 --> 00:01:42,302
NASA has a fleet of strategically placed
spacecraft that work alongside other

29
00:01:42,302 --> 00:01:47,240
missions from NASA and space agencies
around the globe to monitor the Sun

30
00:01:47,240 --> 00:01:48,741
twenty-four seven.

31
00:01:49,175 --> 00:01:53,580
Together, we are working to increase
our understanding of solar phenomena

32
00:01:53,780 --> 00:01:57,817
such as solar flares,
the solar wind, and space weather.

33
00:01:59,052 --> 00:02:00,120
We have missions

34
00:02:00,120 --> 00:02:03,223
studying everything from Earth's uppermost
atmosphere

35
00:02:03,356 --> 00:02:08,161
where the International Space Station
lives, to our 45-year-old Voyager mission

36
00:02:08,361 --> 00:02:11,865
that is investigating the outer boundaries
of our solar system.

37
00:02:12,132 --> 00:02:16,236
We've even had one mission that
has actually entered the Sun's atmosphere.

38
00:02:16,402 --> 00:02:19,405
Parker Solar Probe touched the Sun.

39
00:02:19,606 --> 00:02:22,475
Studying these complex systems
helps us better

40
00:02:22,475 --> 00:02:26,179
understand our universe,
including our solar system,

41
00:02:26,479 --> 00:02:31,284
distant stars, exoplanets,
and our search for life on other planets.

42
00:02:32,051 --> 00:02:35,688
Understanding the Sun's activity
is critical to all of NASA's

43
00:02:35,688 --> 00:02:39,192
endeavors, especially our human
exploration efforts.

44
00:02:39,626 --> 00:02:44,864
It underpins our Artemis missions,
enables us to protect technology on Earth

45
00:02:44,864 --> 00:02:48,134
and in space, helps safeguard
our astronauts

46
00:02:48,368 --> 00:02:51,371
and allows us to voyage to Mars
and beyond.

47
00:02:51,771 --> 00:02:55,508
The Heliophysics
Big Year is a unifying effort

48
00:02:55,542 --> 00:02:59,979
designed to encourage
exploration, creativity, and wonder.

49
00:03:00,313 --> 00:03:03,249
We invite you to engage in the world

50
00:03:03,249 --> 00:03:06,252
around you with intention and curiosity.

51
00:03:06,452 --> 00:03:08,922
We invite you to experience

52
00:03:08,922 --> 00:03:11,925
the annular and total
solar eclipses with us.

53
00:03:11,991 --> 00:03:15,094
We invite you to do science

54
00:03:15,328 --> 00:03:18,331
and to experience our Sun
in different ways.

55
00:03:18,598 --> 00:03:21,467
Throughout the year, there
will be opportunities for communities

56
00:03:21,467 --> 00:03:25,071
across the globe to participate in
Sun-related activities

57
00:03:25,438 --> 00:03:28,841
such as experiencing
solar eclipses and auroras,

58
00:03:29,209 --> 00:03:34,147
joining citizen science projects
such as HARP and Spritacular, creating

59
00:03:34,147 --> 00:03:38,484
Sun-inspired art, music, fashion and food,

60
00:03:38,718 --> 00:03:42,055
and a host of other fun heliophysics
activities.

61
00:03:42,288 --> 00:03:45,658
So, please join us for the
Heliophysics Big Year

62
00:03:45,858 --> 00:03:50,396
and help us celebrate our
extraordinarily ordinary star.
