Station: why Mars?
Station: why Mars?
The speaker explained under the topic "Why
Mars?". She explains that Mars can have potential for life, as she also
explains that Mars's atmosphere can become thinner every time it gets older, and now that Mars's atmosphere has thinned is it possible for humans to
live there.
She explained that Mars is colder than the Earth, as the Earth is
closer to the sun than Mars. Mars is the closest planet to Earth that might
have once supported or even currently supported life. It has water ice, like I
said a thin atmosphere, and some evidence of a past warmer, wetter climate.
Mars is the most Earth-like planet in our solar system. It
has a day and night cycle similar to Earth's, and its polar ice caps are made
of water ice, like Earth's. This makes it a candidate for future human
habitation.
She explained that Mars used to have water, but it got cold
and lost most of its atmosphere. Some water might be underground or locked in
rocks, but Mars is now a dry, dusty place.
It is due to a weakening magnetic field, Mars once likely had
a stronger magnetic field that shielded the planet from harmful particles
emitted by the sun. Over time, this magnetic field weakened, allowing the solar
wind to strip away much of the Martian atmosphere.
A thin atmosphere can
also be one of the reasons, as, without a thick atmosphere, Mars couldn't hold
onto heat as effectively, causing the planet to cool significantly. This frigid
temperature meant any remaining water would freeze or escape as vapor into
space.
She showed us examples of the food that the astronauts
need to eat, the rocks, asteroids, and meteoroids, and how the moon and the
earth orbit around the sun by using a device, and she has also showed us the
types of rocks (example being: sedimentary, semi-precious, igneous, and
metamorphic.)
After all that, overall, she explained about space and why
Mars can have the potential for us to live there.
Station 2:
In this station, the speaker talks about the universe,
astrology, and the solar system.
How can we tell if it is a planet or a star by the telescope?
By their light, the speaker explains that stars do tweak and light up in the telescope
but the planets do not.
Why do the stars twinkle? Stars twinkle because of Earth's
atmosphere. The starlight bends and
jiggles as it passes through different air layers, making the star appear to
flicker from our view. It's like looking
through a rippling pool of water. In
space, where there's no atmosphere, stars shine steadily. That's why in our
point of view, the stars are tweaking or twinkling.
The only planet that is visible to our night sky is Jupiter,
he mentioned that "It will take us 3 years for us to reach Jupiter’s
orbit and 6 years for us to arrive and arrive at the planet itself."
Jupiter is the largest planet in our solar system, the
largest moon of Jupiter is "Ganymede" It's even bigger than the
planet Mercury. Next is Callisto, it has water and is an icy moon with a
heavily cratered surface. Then goes Europa which is the same size as planet Earth
then the last one (or the fourth one) called Io, the volcanic moon of Jupiter.
The solar system's largest storm is called the "Great Red Spot."
Longevity: This storm is a marathon runner, not a sprinter.
It's been raging for centuries, possibly even millennia.
Power: The Great Red Spot packs a punch with wind speeds reaching up to 432 kilometers per hour (268 mph). That's faster than most hurricanes on Earth.
The most gasses we can find here are methane and helium.
And that is the planet Jupiter.
After talking about the planet Jupiter, the speaker decides to go back to the topic of Earth and the stars.
He explained that most stars that we see in the night sky,
is that it can help tell the time and the directions during ancient times.
The most commonly used star is the Polaris.
Polaris (North Star), for cultures in the Northern Hemisphere, Polaris was likely a very important star. It remains almost stationary in the night sky due to Earth's rotation, making it a reliable guide for navigation.
Aside from their names, they were also given stories. Their
stories were based on Greek mythology, and that is why we have the constellations.
A constellation is a group of stars that make an imaginary shape in the night sky. They are usually named after mythological characters, people, animals, and objects.
Among the 88 constellations, the brightest one is Sirius.
Sirius (Canis Major): The brightest star in the night sky, Sirius, also known as the "Dog Star," shines with an intrinsic luminosity 26 times greater than the Sun. It's located in the Canis Major constellation, depicted as the larger dog following Orion the Hunter.
Canopus (Carina): The second brightest star, Canopus, resides in the southern constellation Carina, the keel of the Argo Navis. Due to its far southern position, Canopus isn't visible from most of North America or Europe.
Alpha Centauri (Centaurus): A triple star system, Alpha Centauri is the closest star system to our solar system. The brightest component, Alpha Centauri A (Rigil Kentaurus), holds the title of the third brightest star.
Arcturus (Boötes): Nicknamed the "Bear Guardian," Arcturus is the brightest star in the northern celestial hemisphere. It's located in the constellation Boötes, the Herdsman.
Vega (Lyra): Vega, also known as the "Harp Star," is the fifth brightest star and brightest star in the constellation Lyra, the Harp. Vega is a blue-white main sequence star and is one of the hottest stars among the brightest.
Those are the 5 brightest stars in all of constellations.
Now let us start with the story of Orion. Orion is arrogant and boastful, he brags
about his hunting skills, claiming he can kill every beast on Earth. This
angers Gaia, the personification of Earth itself, who sees him as a threat to
her animal children.
Due to that, Gaia sent a giant scorpion to punish Orion, leading to his eventual death (though often by Artemis' arrow or another cause). Simply disapprove of his arrogance, but do not actively intervene. Zeus put the scorpion in the heavens after it won the battle.
And that is the story behind why Scorpius and Orion are often intertwined in Greek mythology.
Aside from the constellations, there are also things called "Nebulas."
Nebulas are an enormous cloud of dust and gas occupying the
space between stars and acting as a nursery for new stars.
Types of nebulas
South Ring Nebula: South Ring Nebulas are called like that because they resemble the better-known Ring Nebula.
The three types of nebulae discussed are emission,
reflection, and dark nebulae. Emission nebulae emit light, reflection nebulae
reflect nearby light, and dark nebulae do neither, they are black against a starry
sky. One could also argue that three types of nebulas are planetary (for
looks), supernova, and diffuse.
In this station, we had a sight to see stars, nebulas, and
the things that the speaker explained inside of some bouncy place.
Station 3:
In this station, the speaker talked about climate change and
he also discussed some things that require the heat of a palm, the
motion of a bicycle, and the sun.
The speaker also mentioned why climate change can greatly
affect us, how the world can potentially be gone, how we can help, and what ways
we can.
Among the climate change he mentioned are extreme weather,
rising sea levels, water scarcity, food security, and mass extinctions.
If left unchecked, climate change has the potential to harm not
only the planet Earth but to living beings like animals. Sea
levels could rise significantly, submerging entire coastal regions. Extreme
weather events could become so common and severe that large areas become
uninhabitable. Mass food shortages and resource scarcity could lead to societal
collapse and conflict. While this is a worst-case scenario, it highlights the
urgency of addressing climate change.
He mentioned that flowers are blooming in Antarctica,
without context it can be a good thing, but with context, it is seriously a bad
thing. This means that the environment is getting hotter in Antarctica to the
point that flowers are blooming in places they aren't supposed to be.
If the environment is getting hotter, this means that this
is not the right habitat for polar bears as they require snowing surroundings
because their 2 layers of fur help keep them warm even when it's - 40 degrees.
