00:00
humanity will once again visit the moon
00:03
the mission is planned for 2024. in this
00:05
crew we'll see the first women step on
00:08
the moon
00:09
the main goal is to establish a lunar
00:11
base for continued research
00:13
that will help nasa prepare for an
00:14
upcoming mission
00:16
to mars has been planning a crude flight
00:19
to the red planet
00:21
set for the 2030s robotic rovers did a
00:24
good job exploring the martian surface
00:26
but astronauts will have to dig deeper
00:28
to find evidence of water
00:30
and any fossils proving microscopic life
00:33
was once
00:33
possible on our planetary neighbor
00:36
new data on earth-like planets since its
00:40
launch in 2009
00:42
the kepler space telescope has
00:43
discovered lots of exoplanets
00:46
orbiting distant stars some of them have
00:48
an earth-like mass
00:50
composition and orbits nasa plans to
00:53
launch a new generation of telescopes in
00:55
the 2040s
00:56
they'll help us find real twins of our
00:58
planet and even get pictures of their
01:01
surfaces
01:03
the return of halley's comet it'll be
01:06
another
01:06
41 years before we once again see the
01:09
most famous comet in the sky
01:12
halley's visits us every 75 years
01:15
so some will manage to see it twice in
01:17
their lifetime
01:19
the longest solar eclipse 166 years from
01:23
now
01:24
i'll still be around then the sun will
01:26
go dark for 7 minutes and
01:28
29 seconds this is pretty close to the
01:31
predicted maximum
01:33
it'll also be the longest eclipse human
01:35
civilization has ever witnessed
01:37
in its 10 000 years
01:40
arrival of the most notorious asteroid
01:44
1950 d.a was once the most probable
01:48
candidate among near-earth
01:49
objects we know to actually strike the
01:51
planet
01:52
fortunately the chance was later
01:54
estimated to be not even
01:56
a tenth of a percent it'll most likely
01:58
pass by
01:59
on march 16 2880 mark your calendars
02:03
and it'll become solid evidence that
02:05
we're safe for a while
02:07
the asteroid is more than a mile in
02:09
diameter enough to take out life on a
02:11
planet
02:13
a new north star the earth spins like a
02:17
top
02:18
watch one of these toys closely and
02:20
you'll see how its tip starts to draw
02:22
circles in the air
02:23
the earth's axis an imaginary line going
02:26
through the poles
02:27
goes full circle once every 26 000 years
02:31
it points at different stars along the
02:33
way thus changing the north star
02:36
by the year 3000 the gamma suffistar
02:39
will share this title with polaris as
02:41
the earth's axis will point
02:43
right between them the first near-earth
02:47
supernova and teres is the 15th
02:50
brightest star in the night skies
02:52
it's also an old red supergiant 12 times
02:55
larger than the sun
02:57
stars this massive age to a point where
02:59
they collapse
03:00
in on themselves producing huge
03:02
supernovas
03:04
for antares this will happen just 10 000
03:06
years from now
03:07
which is nothing for a 12 million year
03:09
old star
03:10
the resulting burst will be too far away
03:13
to affect life on this planet negatively
03:15
but the light show will be visible here
03:17
on earth even during the day
03:21
message to the universe delivered
03:24
arecibo
03:25
is the encoded message describing
03:26
humanity life on earth
03:28
and the advancement of our scientific
03:30
knowledge it was broadcast from the
03:32
arecibo radio telescope
03:34
and aimed at the center of the m13
03:37
cluster
03:38
25 000 light years away from us in 25
03:41
000 years
03:42
it'll finally reach its destination
03:46
a new closest star about 36 000 years
03:50
from now
03:50
the ross 248 star will become our new
03:53
closest neighbor
03:55
it'll be just three light years away
03:57
from us and overtake the title from
03:59
proxima centauri
04:00
which is a bit more than four light
04:02
years away ross 248 will remain the
04:05
nearest star for around 9
04:06
000 years and then move away once again
04:10
so you didn't like the neighborhood or
04:11
what
04:13
the first interstellar human-made object
04:17
in 40 000 years voyager 1 will reach a
04:20
point within 1.5
04:22
light years of the gliese 445 star
04:25
it successfully reached interstellar
04:27
space in 2013
04:29
but unfortunately it won't be able to
04:31
power up any of its systems somewhere
04:33
beyond the year 2025.
04:35
voyager 1 has a message too a recording
04:38
of greetings in 55 languages
04:41
music from classical to rock and roll
04:43
and sounds of the earth's wildlife
04:46
a bear saturn one hundred thousand years
04:50
from now
04:50
saturn will lose its beautiful rings
04:53
it'll happen gradually over time
04:55
as the planet's colossal gravity pulls
04:58
rocks and
04:58
ice from this belt floating around it
05:01
they'll all eventually
05:02
fall and get crushed and burned by
05:04
saturn's atmosphere
05:05
well how rude the ring system is in the
05:08
middle of its life cycle
05:10
so we're incredibly lucky we got to see
05:12
it in its full glory
05:15
the most frightening supernova the wr
05:18
104 star will burst into a supernova in
05:21
three thousand years
05:23
this star is 75 000 light years away
05:25
from us
05:26
and the blast won't touch us at all but
05:28
there is
05:29
a small chance it'll also produce a
05:32
gamma ray burst in the process
05:34
if this stream of energy happens to aim
05:36
right at us
05:37
it will negatively affect life on earth
05:40
good news
05:41
scientists say that's very unlikely
05:45
colliding moons the moons of uranus are
05:48
part of a highly unstable system some of
05:51
them have orbits that cross
05:53
paths uranus already has two rings of
05:56
debris from
05:57
past collisions of its natural
05:58
satellites destimona and cressida will
06:01
crash
06:01
into each other in the next million
06:03
years and produce
06:04
new rings a star
06:08
too close for comfort the rogue gliese
06:10
710 star is approaching our solar system
06:13
and it will get just one light year away
06:16
in 1.3 million years
06:18
this won't have a major impact on the
06:20
planets but it could disturb the
06:22
so-called orc cloud
06:24
which surrounds our solar system and is
06:26
full of comets
06:27
from earth the star will look like the
06:29
brightest planets we see now
06:31
and we'll see many more comets in the
06:33
skies
06:35
the closest star to ever go supernova
06:38
within a few million years the spica
06:41
star which is only 240 light years from
06:44
us
06:44
will burst into a supernova supernova
06:47
are a problem for life when they're
06:49
three times closer than that
06:51
but the supernova itself will shine in
06:53
the earth's skies as bright as a full
06:55
moon
06:57
a time capsule for future generations
07:00
the lagios logios1
07:01
satellite was launched back in 1976 to
07:04
gather information
07:05
about the exact shape of the earth and
07:07
tectonic plate movement
07:09
but it also contained information about
07:11
civilization on earth at the time
07:13
it'll re-enter our atmosphere in 8.4
07:16
million years
07:17
if humanity is around then they'll learn
07:20
how life on earth was in our time
07:22
well at least how it was some 40 years
07:24
ago
07:26
rings for mars mars moon
07:29
phobos orbits really close to the
07:31
surface and it continues to get two feet
07:34
closer every century
07:36
50 million years from now it'll collide
07:38
with mars
07:39
resulting in a massive amount of debris
07:41
going into orbit
07:42
and forming a ring system around the red
07:45
planet
07:46
oh can't wait for that
07:49
days on earth will get longer now really
07:53
1.4 billion years ago the moon was much
07:56
closer to our planet
07:57
it made the earth rotate faster so the
08:00
day was only 18 hours
08:02
the moon is continuously moving away
08:04
from earth
08:05
in 180 million years we'll gain
08:08
one extra hour in a little over 2
08:11
billion years
08:12
a day on earth will be 36 hours long
08:16
no more solar eclipses 600 million years
08:20
into the future
08:21
the moon will move away from the earth
08:22
too far to cover the sun during eclipses
08:25
those will become ancient relics
08:29
the sun will get too bright it'll take
08:32
about a billion years for the sun to
08:34
raise its luminosity by 10
08:36
this will be devastating for planets in
08:38
the solar system
08:40
and life on earth won't be possible
08:42
beyond this point
08:43
by then our species will likely have
08:45
found a new planetary home
08:48
the sun will swallow the inner planets
08:51
in 5 billion years the sun will begin to
08:54
evolve
08:54
into a red giant growing hundreds of
08:57
times its current size
08:58
it'll swell up so much it will
09:00
eventually engulf
09:02
mercury venus and possibly earth
09:05
the new goldilocks habitable zone may
09:08
shift to the orbits of jupiter and
09:10
saturn
09:10
this process will take a bit under 3
09:12
billion years
09:13
until the sun reaches its maximum size
09:16
after that our star will shrink into a
09:19
white dwarf
09:21
the most epic event ever around the same
09:24
time
09:25
our sun is swelled up the nearest
09:27
neighboring galaxy
09:28
andromeda will come too close to the
09:30
milky way
09:32
if we could watch our galactic neighbor
09:34
at this time it'll get larger and larger
09:36
as it approaches
09:38
then the two galaxies will start to
09:40
merge
09:41
bright blue stars will burst into life
09:44
new constellations will form
09:46
the two spiral galaxies will now be a
09:48
single giant elliptical one
09:51
wow i've set an alarm on my smartphone
09:53
so i don't miss it
