hi it's katrina
number 10
earth 2.0 for the first time ever we may
have found a planet just like earth the
transiting exoplanet survey satellite
codenamed tess has discovered the first
planet ever that's the perfect distance
from its star to support life and is
about the same size as earth it might
even have water
nasa hasn't actually detected liquid
water but the conditions suggest it is a
possibility
the planet is being called toi 700d
and it's one of only a handful of
planets the same size as our own within
a particular star's habitable zone the
other planets like this that we know
about have all been discovered by the
kepler space telescope but tess is a
little bit different it launched
specifically to search for potentially
habitable planets just like earth it
does this by monitoring a large part of
the sky known as a sector for 27 days
before moving on to the next
this incredibly long stair allows the
satellite to track all changes in
brightness that would be caused by a
planet orbiting its star
as for toi 700d it's only about 100
light years from us
located in the southern constellation
dorado its star is about 40 percent the
size and mass of the sun and only half
its surface temperature
this means it's significantly smaller
and colder than our own star
but because of the proximity of earth
2.0 to this mystery star the situation
is perfect for breeding habitable life
the big problem is that we have no
possible way of knowing if any life is
thriving
but if the planet has a similar
temperature to our own and liquid water
it would be a perfect candidate for our
first intergalactic colony what do you
think are you ready for it let me know
in the comments below number 9. liquid
on titan on the largest moon of saturn
titan scientists have detected giant
canyons flooded with liquid hydrocarbons
the information comes to us thanks to
data received from nasa's cassini
spacecraft the spacecraft took some
amazing photographs of very deep canyons
on the surface of the moon which
researchers are now confident in saying
are dark channels spreading out from the
lygeiamar sea totally filled with liquid
this discovery was the first time that
scientists were able to put forth real
evidence that titan has liquid filled
canyons but of course this isn't liquid
water for those who don't know titan is
a frigid and very cold moon the second
biggest in the solar system with large
bodies of liquid methane the moon is
completely crusted over with hydrocarbon
ice and it has lakes and rivers of both
liquid methane and ethane it also has a
thick atmosphere that scientists believe
is a prime example of what the
conditions were like when our solar
system was first created it's true that
scientists already knew about titan's
methane seas but they hadn't known about
the canyons
nasa says they believe the canyons may
have formed just like the grand canyon
here on earth from thousands and
thousands of years of a flowing river
carving them out
these canyons are almost 2000 feet deep
in some places and they are filled to
the brim with black liquid methane
oh yeah and the surface temperature here
is about minus
289 degrees fahrenheit
number eight emissions from an alien
world
scientists believe they may have
potentially detected radio emissions
coming from an alien planet beyond our
system for the first time in history the
astronomers behind the detection used a
radio telescope in the netherlands to
study a trio of stars that host
exoplanets the researchers noticed that
one star system really stood out from
all the others called tau boots the
radio signal they picked up was so
strong and so polarized that they
believe it must have come from a
planet's magnetic field
this is according to jake turner from
cornell university the lead author of
this new and exciting research
this planet is about 51 light years from
earth in the constellation boots and if
you're wondering how an alien planet is
able to emit signals that we can pick up
here on earth it all goes back to
jupiter
these researchers first studied the
kinds of emissions that were coming off
jupiter's surface they then tweaked
their measurements to reflect a greater
distance from earth and pointed the
radio receiver deeper into the universe
it really all comes down to how powerful
a planet's magnetic field is
this is just the tip of the iceberg when
it comes to detecting alien planets
once scientists perfect the art of
picking up radio emissions they'll be
able to see planets with magnetic fields
very far from us
they'll also be able to tell a lot about
the planet's history based on its
magnetic field number 7 the hum of
plasma waves as of right now the voyager
1 spacecraft is somewhere around 14.1
billion miles from the planet the planet
earth of course it's moving at an
outstanding speed of 38 000 miles per
hour and not too long ago it passed
across the boundary of our solar system
and entered into the true gulf of space
and yet despite this immense distance
voyager 1 is still sending information
back to us and yes it is still making
new discoveries
one of these discoveries came to us in
the form of a sound hearing a sound in
space doesn't really make a lot of sense
for one main reason there is no sound in
space
sound cannot flow through an empty
vacuum it needs air to travel or at
least something that can act as a medium
for the sound waves to pass through
scientists believe the sound managed to
reach voyager 1 by traveling through
space on invisible gases
the actual sound was the hum of plasma
waves moving through space
these plasma waves were created by our
very own sun
according to the nasa researchers a
solar wind carried gas billions of miles
away from the sun when it expelled a
burst of plasma it was probably the
result of a solar storm on the star's
surface when plasma spiked and a small
burst of it got shot into space
over 14 billion miles away voyager 1
actually picked up the sound of our sun
basically belching
number six
ice volcanoes nasa has made yet another
outstanding discovery on the dwarf
planet series this time in the form of
icy volcanoes
ceres never did get big enough to become
an actual planet instead getting the
less popular title of dwarf planet but
even though this little piece of rock
isn't technically a planet it still has
some pretty impressive geological
features
observations from nasa's dawn spacecraft
have shown that the little planet could
be harboring cryovolcanoes at the bottom
of some of its craters
now keep in mind that ceres is located
between mars and jupiter it's a piece of
rock mostly covered in ice and a lot of
this ice may actually be building up
underground just like lava builds up
under volcanoes here on earth the
cameras on the dawn spacecraft showed
physical flowing material just like lava
at the bottom of the craters except less
viscous and tinged blue
it's the same color as material found at
the top of a mountain on ceres that
scientists believe once erupted with a
mixture of ice and mud the theory now is
that the flowing material is of a
similar mixture inside the craters it's
ice mixed with mud and salt and
scientists say it could be erupting out
of the weakest points on the dwarf
planet's surface to make things simple
it's ice volcanoes ceres literally has
volcanoes erupting out icy mud instead
of lava which do you prefer let me know

number five the mars bug
a scientist from ohio has made a wild
claim that there are insects on mars
he's based this claim on supposed
photographic proof from various nasa
mars rovers throughout the years his
name is william ramoser and he isn't
actually a crackpot he is a professor
and a specialist in the study of viruses
transmitted by arthropods at ohio
university his evidence is pretty shaky
really only coming from his own
interpretation of the photographs
meaning that it can only be considered
theory and isn't currently verifiable he
presented his bizarre findings at a
national meeting held by the
entomological society of america
he showed photographs taken from the
mars rovers that seemed to show tiny
insects with legs abdomens heads and all
the other insect parts and he claims
there is diversity as well with a lot of
different kinds of bugs on the red
planet
but according to other scientists he's
completely delusional pretty much
everybody except him says that he's
finding insects where there aren't any
he's looking at rocks and interpreting
them as insect fossils he's doing this
in the same way that one might look at a
cloud and interpret a dragon either that
or he's completely right and everybody
else is just trying to cover up the fact
that there are indeed insects on mars
what do you think are there really
insects on mars or is this guy just
practicing some wishful thinking let me

coming up number four
merging black holes
scientists have discovered a collision
between two super massive black holes
it's one of the most catastrophic and
destructive things that scientists have
ever seen out in the universe the pair
of supermassive black holes are the
nearest ever discovered to our planet
astronomers say they are currently
merging into a single monstrosity of
unbelievable proportions
it's happening about 89 million light
years away from us in a galaxy called
ngc 7727
scientists have been measuring the mass
of each of the black holes by watching
how gravity affects the movement of the
nearby stars
observations with the european southern
observatory's very large telescope have
shown the two giant black holes are only
1600 light years away from each other
in cosmic distance they are basically
breathing in each other's faces this
small separation between the black holes
suggests that they will merge into one
giant massively supermassive black hole
within the next
250 million years
this is what holger baumgart says a
professor at the university of
queensland australia and to give you an
idea of just how powerful these
celestial objects are the bigger of the
two contains the mass of 154
million suns
the smaller one only contains the mass
of 6.3 million suns but still the power
of these celestial bodies is completely
insane they aren't a danger to us but
you definitely wouldn't want to fly your
starship anywhere near them
number 3
dark matter stars there is a possibility
that stars compose totally of dark
matter once populated the universe this
isn't a true discovery more of a theory
but one that's quite interesting anyway
scientists say that when the big bang
first happened the universe was much
smaller than it is today
in the smaller environment dark matter
came into existence and it was then that
scientists believe that dark stars may
have been born but here's the twist
dark matter stars wouldn't have actually
been dark instead they would have been
the biggest and brightest objects in the
universe
no one has ever seen one with their eyes
at least no human ever has but we are
currently looking
and if you're a bit confused about dark
matter so is everybody else scientists
say that at least 26 of the universe is
made of dark matter and that thousands
of these particles pass through your
body every second it's just impossible
to detect and study because dark matter
is intangible it emits no light and it
only leaves a gravitational fingerprint
behind
in the case of dark matter stars huge
collections of this material began to
cluster in patches eventually forming
the first stars in the universe right
after the big bang kick-starting the
formation of normal stars and then
galaxies
but as the universe continually expanded
dark stars became irrelevant died and
probably went extinct
number two
water worlds
in a shocking new study researchers are
suggesting that there are exoplanets
outside our solar system that are
completely covered in water these are
water worlds with oceans deeper than
anything we have ever seen before
and by deeper than anything i'm talking
hundreds or even thousands of miles or
kilometers deep the study was done by
astronomer lee zhang of harvard
university and his colleagues zhang
explained that based on his team's
computer simulations earth's oceans are
basically puddles compared to what's
lurking out there on planets outside our
solar system for example the maximum
depth of the ocean on earth is at the
bottom of the mariana trench about 6.8
miles but there are water worlds out
there that are two or even four times
larger than earth with global oceans
these planets likely formed much further
away from their host stars than they are
today as giant balls of ice
but as they drifted closer to their
stars and got warmer that ice melted and
their gravity was increased causing the
surface ice to turn to water and create
oceans thousands of miles deep and where
there's water there is almost always
life
just imagine a planet with an ocean one
thousand times larger than any we have
and the life forms that must be lurking
within it
number one
weird moon substance
chinese scientists found a weird
substance on the far side of the moon it
happened last year with their u22 rover
stumbling across a curious substance
that nobody could immediately identify
at first the discovery sparked intense
interest among lunar scientists because
it didn't look like anything seen on the
moon before
however after a year of analyzing what
appeared to be some kind of gel
scientists say the substance is actually
made up of rock
they used a process called spectral
unmixing to see what the most likely
composition of the substance was
according to the researchers the
material is dark green it glistens and
there is a pile of it about 20 inches
long they found the presence of glass
suggesting it was created during an
impact event there was some kind of
impact that caused minerals to cement
together and form a black glossy
glass-like material
it never ended up being mysterious space
goo like so many people thought at first
just the leftover rock residue of some
past event that generated serious heat
it could have been from a space rock
crashing into the moon it could have
even potentially been from some kind of
ship taking off with its thruster
melting the surface rock into a type of
craggy glass
