big news from the Juno spacecraft right and obviously this is a artists
impression of Juno in close to Jupiter Juno we arrived at Jupiter last July and
has been orbit around Jupiter has a 53 day of it where it takes it far away
from Jupiter and then close to Jupiter and when it's close to Jupiter its its
closest point is called a para Jove and it's on its perigee ov6
mission actually which happened May 19th and will show a few images from that
mission and there it's closest approach and then also go into some of the
scientific results that came out of a recent teleconference first image we'll
look at is the southern hemisphere and you can see those five little dots here
or what there are little ovals they're called pearls and we then we're
going to take a look at the next slide which is a Juno shot and this is the raw
image that comes in and is posted on the Juno cam page and you can see the you
can see those poles which are kind of up here so we're looking very much down in
the southern hemisphere something that we can't see from Earth because we're
actually looking towards the equator of Jupiter so these are very unique views
and views that we've never seen before of the of the polar regions and then
once the pictures are posted the public will enhance them and this is a really
nice super enhanced picture showing of details of the bands and and also these
swirling storm like features we incurred in the next slide and we'll look at an
area down over here we can just barely see in this telescopic picture and we'll
look at the Juno picture of this area in super enhance detail and what that
actually is is this swirly cloud feature that we see right over here notice that
the polar region is very much turned kind of darkish blue
compared to the low allowed to its which are more brown and beige color we're
going to turn go to the next image and we're going to turn Jupiter around and
this is the north and this is the south and so with that we can orientate our
Jupiter with the images and we'll the show next and if you look in this area
we can see one of the poles and another pole and there's there's this band in
between and also this large broad band known as the southern equatorial belt
and this is taken from a distance of 8,000 miles this is the huge equatorial
band and it looks like it dominates this picture but actually has you've seen in
the previous image it's it's only kind of like it's not that big compared to
the overall that big when I say that big is it's actually I'm here to here it's
4,000 miles across just to give a sense of scale we go to the next slide and we
can see an even closer look at the south so negatory or band which has these
little specks here and because we're so close to the cloud tops of Jupiter these
individual specks we would not normally see but we can see them now in detail or
actually tiny little storms just about 30 miles across and 30 miles high and
you can just bet you can see the cast the shadows they cast I think you can
just barely see them and that's how you can calculate roughly how big these
storms are it's believed that there are the lobe and the made out of ice or
ammonia and it may be snowing or ammonia ice or or just snow down on the clouds
below I will go to the next slide and we can see that the two features the two
poles actually and this is called this thing here is nicknamed the world in
between the poles I don't know why I put some of the world
whir yeah well between well then the poles okay let pain I'm just by the way
this this is about 1/2 off diameter just just to give you
let's go okay let's go to the next slide and up in the northern region of Jupiter
there is an area you can just barely see it it's just this dark feature here
known as the great polar spot and when we go to the next image was taken right
you know you can see an enormous swirly storm and it's so big that it actually
cast a shadow so it indicates it's at higher level above the base level of
Jupiter's Karl's okay so those are the images there are a lot more I wish I
could show but we're gonna go to the science results this is basically
artisan impression showing Juno and it's peridot have close to Jupiter and it
takes about two hours from to go from here to about here but it just shows you
the lobes that you see here or the magnetic field which is very strong and
that the manna feels so strongly to a tricked trap radiation and the radiation
inside those between those magnetic fields is about 20,000 times higher than
the radiation belts of which is enough to destroy a spacecraft like Juno if it
flies through a Juno avoids the radiation belts which are shown in the
orange for most of its fly through then goes partway into the radiation belts
but it's moving very fast as closest point to Jupiter it's moving about
130,000 miles per hour so it only gets a fried a little bit but it's protected by
that the spacecraft has a is protected by a titanium bolt and so other
instruments there inside are protected so they don't really get fried let's
look at this image this is some ultraviolet imaged of Jupiter's Aurora's
this trail here is caused by electrons from IO drifting down into Jupiter's
atmosphere I always a moon of Jupiter IO is a movement of just okay and what's so
interesting about this image is that the the Aurora which is in ultraviolet and
in a false color here the green and the white is mainly from electrons
interacting with Jupiter's hydrogen of the atmosphere and the red is electrons
coming from the cloud tops and and then zoom energy actually moving into
Jupiter's magnetosphere which is a very different dynamic of how we expect or
Aurora's to form on earth they're mostly the interaction of solar particles with
our nonane field another interesting result comes from Juno's infrared matter
which shows you the regions which are warm and the regions which are cold
regions which are very warm are the brighter regions here this is the main
South Equatorial belt and you can see it's a very cold region there's a red
spot which is also interestingly a cold region and the poles down here are also
cool as well Juno spacecraft has several microwave detectors in fact six of them
and it can actually pair down to about 220 miles below the cloud tops of tjuta
and reveals some of the dynamics below and what's so interesting is that this
red orange region is mostly ammonia the material that ammonia gases and other
materials and you can see its profile is that it actually Wells up towards the
cloud tops of Jupiter near the equator there and so this gives us an
interesting view of some of the dynamics that's happening below
Jupiter's cloud tops that we've never seen before our current view of
Jupiter's atmosphere and all the way down from the top meteorological layer
to the interior is that we we mostly have studied and especially with Juno 12
bars of pressure 12 to 20 bars of pressure
one bar is the air pressure of this room this is our sphere pressure so as you go
deeper the pressures the air pressures increase what Juno will need to
determine and using its gravity and detectors is
whether jupiter has a solid call which we see in as still in question and and
also whether it has a radio a zone where it there's a lot of heat
driving the convective zone above so there's a lot more to learn but this is
our current current model of what we think the interior of Jupiter is and
with more flying more pair of jobs I should say there will be more
information and then we can reveal a little bit more about the internal
structure of Jupiter metallic metallic hydrogen is hydrogen gas that's
compressed under very great pressure it becomes a solid and it has metal like
properties and it's a superconductor it is a superconductor lattice and then the
electrons can go very easily this lattice of protons I have a question if
I may and just struck me looking at when those pictures I know they're just
getting the data and they must be flooded by it but you know all that you
read did you see anything did anyone mention anything about really revisiting
the shoemaker-levy 9 impacts and what it dredged up you know I was looking at
that model that you had and there were a lot of mysteries around that and I just
wanted if you read anything I'm sure the people will be doing that but I am
struck by that yeah I didn't come across an end like that but that would be very
interesting yeah see you know what the dark material obviously it was what was
the remnants of the comet but something how deep did it excavate exactly how
toss of Jupiter okay and then we'll go to the next video this is very
interesting god Juno has four star trackers and one of his star trackers
while it was in peridot was able to image that line there which you see and
in the background you can see the constellation of Orion that line is
actually Jupiter's ring and we know that it's a ring because we've seen it in
other pictures from from Voyager back in the 70s and we go to the next
image just to show you that indeed is the constellation of Orion there's about
there's Betelgeuse and the the ring going outwards so this is we're from
inside of the rings of one of the first pictures taken and to sum it all this is
the perigee of sequence from from northern Jupiter to seven Jupiter and
then we'll finish off with video shown the actual flyover kind of animated
based on these images and as you can see when you get when this Juno got close to
Jupiter the pictures it was going really fast 130,000 miles per hour and the
camera literally had to parent to be able to not have those pictures be
blurred a pair of Jove about 3,000 miles closer than any spacecraft ever
I guess you're about the only person around that doesn't have TV coverage of
the season and I don't mind it man they've got the flag up now
at one
but biathlete
