Most MYSTERIOUS Recent Discoveries By NASA!


From new discoveries on Mars, to solving mysteries
in the depths of space, here are 9 recent discoveries made by NASA Water on Mars
Many books, TV shows, and movies have fantasized about colonizing the planet Mars. The only problem is that Mars is not a place
that can sustain life in its current state, and just as bad, it does not have any water…or
so we thought. In 2018, scans from the Mars Reconnaissance
Orbiter discovered that formations on the planet were actually caused by water that
is still there right now. This was a confirmation based on a finding
of “hydrated salts” on certain slopes of the planet. John Grunsfeld, astronaut and associate administrator
of NASA’s Science Mission Directorate in Washington said that “Our quest on Mars
has been to ‘follow the water,’ in our search for life in the universe”. Now they finally have the science to back
up what they have long suspected. There is briny water flowing on the surface
of Mars. This discovery changes very much what we think
of Mars. If it does have the capacity for water in
its current state, this means that colonization of the planet is not only an option, it could
be adapted to be habitable. Not that I want to run and live there but
I know some people are excited about the idea! “It took multiple spacecraft over several
years to solve this mystery, and now we know there is liquid water on the surface of this
cold, desert planet,” said Michael Meyer, lead scientist for NASA’s Mars Exploration
Program at the agency’s headquarters. “It seems that the more we study Mars, the
more we learn how life could be supported and where there are resources to support life
in the future.” Are you excited?? 8. Multiple “Earths”
In February 2017, NASA discovered that there might be 7 Earth-like planets orbiting a dwarf
star called TRAPPIST-1. In fact, all seven of these planets were found
in the same galaxy, which is a very rare thing indeed. As you know our Earth is a very special planet,
it has an atmosphere that has oxygen (amongst other gasses) and thus allows life to breathe
and grow. It is orbiting a sun that doesn’t bombard
our planet with too much heat, or radiation, nor does it give it too little. We are in the perfect Goldilocks zone! Finding another planet that is like Earth
is actually extremely hard, as these conditions are very specific. So to find seven that could possibly have
similar conditions to ours is quite the breakthrough. Not only that, they are about the same size
as Earth, and some of them (based on pictures and scans) do appear to have water. Should this be true, and should we be able
to reach them, there could be life on these planets or could be a major colonization option
for Earth. You know, because that’s what everyone really
wants to hear! If this water is like our own, it is reasonable
to expect there to be life in the water, and it gives it a much higher chance that that
is the place where the first life outside of Earth might be discovered. 7. Liquid on Titan
Saturn has 53 moons that have been named by scientists, and more could actually be named
in the future. One of the most popular of these moons is
the one known as Titan. It’s been the source of much research, and
has even been home to an alien race in the Marvel Comics Universe. During a scan by the Cassini Space Probe of
NASA, they found that in certain gorges and canyons of Titan, there are actually pools
of liquid, specifically hydrocarbons. This find is important because at first, scientists
didn’t know what was in these canyons. NASA reports that the branching channels appear
dark in radar images, much like Titan’s methane-rich seas. “Previously it wasn’t clear if the dark
material was liquid or merely saturated sediment.” As for how they got there, many speculate
that it is actually the same way the Grand Canyon was formed in the United States. Meaning, they think that there is an underground
river in Titan somewhere, and it eroded the ground until it formed these massive canyons,
and then filled them with liquid. Alex Hayes, co-author of the study, said in
a statement that: “Earth is warm and rocky, with rivers of water, while Titan is cold
and icy, with rivers of methane. And yet it’s remarkable that we find such
similar features on both worlds.” Pretty cool right?? 6. Comet Soup
In 2005, NASA sent their Deep Impact spacecraft into a comet called Tempel 1. If you’re curious as to why they would destroy
one of their craft by crashing it into a comet on purpose, it is because they wanted to analyze
the content and particles that were released from the impact. Scans from the craft before crashing, mixed
with observations from the Spitzer Telescope, revealed that many of the ingredients were
already known common ingredients such as silicates and sand. BUT, some things like clay, carbonates, iron-bearing
compounds and “aromatic hydrocarbons” were quite the surprise since these things are
found on Earth in barbecue pits and car exhaust. These ingredients form the basis of what is
known as “comet soup”. It is the hope of NASA that by studying these
“ingredients”, and getting more samples that they can figure out more about how our solar
system was formed. 5. Death of Saturn’s Rings
The Rings of Saturn are not only the most defining features of the planet, but also
one of the most recognizable things in all of our solar system. Strangely enough NASA speculates that the
rings are “dying”. More accurately, NASA states that the rings
are losing the moisture in the rocks that form the rings. The moisture itself is being pulled into the
planet due to gravity, and thus, the rings are slowly but surely breaking down. James O’Donoghue, a space physicist at NASA’s
Goddard Space Flight Center, said that We are lucky to be around to see Saturn’s ring
system, which appears to be in the middle of its lifetime. An interesting point he makes is that if rings
are temporary, perhaps we just missed out on seeing giant ring systems of Jupiter, Uranus
and Neptune, which have only thin ringlets today!” Maybe all of the gas giants had them at one
point! As for when the rings of Saturn will truly
“disappear”, it is believed it will take another 300 million years, but NASA has also stated
it could happen much faster depending on how fast the moisture continues to be drained
from the rocks. But eventually it’s going to happen. 4. Jupiter’s Orbit
NASA has long tried to get a spacecraft into Jupiter’s orbit. But because of conditions in the planet’s
atmosphere, it’s been a very difficult task. Not to mention, getting a craft near the planet
in terms of its position in space is also hard. Yet, on July 4th, 2016, the Juno became the
first spacecraft to make it into Jupiter’s orbit, which by NASA’s own admission was one
of the hardest things they’ve ever done. The Juno is a solar-powered spacecraft, and
it was sent to Jupiter to learn more about the planet through pictures, videos and scans. Already, it has sent back video of storms
taking place on the planet’s surface, as well as a volcanic eruption happening on the
nearby moon of Io. 3. Supermassive Black Hole
The Hubble Space Telescope is one of NASA’s biggest tools in regards to searching deep
space for new discoveries, and in February of 2016, the telescope took a picture of a
galaxy and found a black hole of astonishing size. This was found in galaxy NGC 4889, in what
is known as the Coma Cluster. The black hole in question is 21 billion times
the mass of the sun in our own galaxy. To those who don’t recall, black holes are
a pocket of space where the gravity is so intense that nothing escapes it, not even
light. Anyone or anything that is caught in this
gravitational field is instantly stretched beyond recognition into spaghetti! (Maybe, it’s just a theory). To find a black hole of this size in a singular
galaxy is something few ever expected. Just as unexpected though is that this particular
black hole doesn’t seem to be “feeding” anymore. Meaning it isn’t drawing in matter that surround
it like it used to. This is quite rare and may offer proof that
black holes can “evolve” over time. Maybe at some point they shut down, offering
another sliver of information to help us learn more about black holes. 2. Ice Volcanoes
On Earth, volcanoes spew fire, ash, soot, and smoke, but on the dwarf planet (a planet
that never matured to full size) called Ceres, the volcanoes shoot ice! This was discovered by NASA via their Dawn
Spacecraft in 2015, which was observing Ceres (which orbits between Mars and Jupiter). The technical term for these are “Cryovolcanoes”,
because instead of fire and ash, they could potentially shoot out ice and mud. This is based on the fact that Ceres is covered
with ice both above and below its surface. To that end, should these structures “erupt”,
the only thing it can shoot is ice. Ralf Jaumann of the German Aerospace Center
says“The members of the (Dawn science) team expected a lot of things, but not what we
finally got! He says “I was completely surprised, and
‘completely’ means ‘completely.’ ”
Though obviously unproven in terms of the “eruption’ aspect of the cryovolcanoes, it
does make sense given that the temperature in the craters of Ceres can reach 350 degrees
below zero. But how would an ice volcano form? And what would cause it to shoot ice? Fun fact: the discovery via the Dawn spacecraft
was actually the first time Ceres had even been explored by such a device. 1. Reaching Ultima Thule
4 billion miles away from Earth, there is an object known as Ultima Thule. This “celestial body” is actually two round
objects made of an unknown composition that are actually fused together. NASA has released the first up-close stereo
images of this celestial body via the New Horizons spacecraft, making this the most
distant object that a spacecraft from Earth has ever explored. The New Horizons spacecraft was able to get
within 2200 miles of the mysterious “body”, and through its scans and pictures, were able
to find some very interesting information about the formation. First, both “lobes” of Ultima Thule were similar
in shape and in color, inferring that this was actually formed from the same ‘source’. Despite the object being 21 miles at max length,
it does not have an atmosphere, nor is its gravitational force strong enough to pull
in other objects. Ultima Thule resides in what is known as the
Kuiper Belt, also known as the “Twilight Zone”, and the New Horizons spacecraft is not only
very deep into it now, but it’ll continue to explore it and continue to make new discoveries. Thanks for watching! What did you think about these amazing discoveries
