Potential for Life
Does our Moon have potential for life?
The Moon's weak atmosphere and its lack of liquid water cannot support life as we know it.
Io is a moon orbiting ...
a) Saturn c) Jupiter
b) Venus d) Neptune
c) Jupiter
Who has stepped first on the Moon?
Neil Armstrong- July 20, 1969 during the Apollo 11 mission.
1) Callisto might have thin carbon dioxide atmosphere, or exosphere, on Callisto, together with hydrogen and oxygen in its atmosphere;
2) Callisto is Jupiter’s second largest moon after Ganymede and it’s the third largest moon in our solar system.
3) Callisto doesn't have rings
4) There is evidence of a subsurface ocean on Callisto, putting Callisto on the list of possible places where life could exist beyond Earth.
Did you know, that Io might have its own...
a) magnetic field c) brown dwarf
b) small black hole d) life
An iron core may form Io's center, thus giving Io its own magnetic field.
It is proved that Europa has an extremely thin oxygen atmosphere- far too thin for humans to breathe. And Europa's surface is mostly solid water ice, it is crisscrossed by fractures. Does Europa have potential for life?
Abundant liquid water, energy and the right chemical elements make Europa one of the best places in the solar system to seek present day life beyond Earth.
Io has the highest ... of any moon, and has the lowest amount of water of any known astronomical object in the Solar System.
a) mountains c) density
b) speed d) volume
c) density
Define the "Moon"
The Moon is Earth’s only natural satellite – a celestial body that orbits a planet. Its orbit around our planet is shaped like a slightly squashed circle known as an ellipse.
Io(satellite of Jupiter)
The moon Io is the most volcanically active world in the solar system. Io even has lakes of molten silicate lava on its surface.
What is so unusual about Triton, the satellite of Neptune?
It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit.
It is proved that Io is larger than our Moon. Does Io have potential for life?
Constant volcanism and intense radiation make Io an unlikely destination for life.
Io’s very thin atmosphere is primarily sulfur dioxide, which on Earth is sometimes used to...
a) grow tomatoes c) grow potatoes
b) preserve dried food d) oxidize food
b) preserve dried food
When and how our Moon was formed?
About 3 billions years ago or so, when the Earth was hot and bombarding with asteroids, the Earth collided with a protoplanet, and big part of the Earth was blasted into space. Today, we know it as the Moon.
Phobos and Deimos(Moons of Mars)
They are irregular in shape.
Saturn’s largest moon Titan is an extraordinary and exceptional world. Among our solar system’s more than 150 known moons, Titan is the only one with a...
a) no atmosphere c) black hole
b) substantial atmosphere d) planet nearby
b) substantial atmosphere.
And of all the places in the solar system, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes and seas on its surface.
Does Titan have potential for life?
Titan is POTENTIALLY HABITABLE. Titan’s subsurface ocean might be a place where life as we know it could exist, while its surface lakes and seas of liquid hydrocarbons might be places to look for life as we don’t know it.
A bit larger than Earth's Moon, Io is the ... largest of Jupiter's moons, and the ... one in distance from the planet.
a) third, first c) third, fifth
b) fifth, third d) first, fifth
c) third, fifth
A bit larger than Earth's Moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet.
Why do we have low tides and high tides?
Tides are caused by the Moon. When the Earth rotates, the bulges move around in the oceans, causing the high tides and low tides in oceans all over the world.
Enceladus(satellite of Saturn)
About as wide as Arizona, Enceladus also has the whitest, most reflective surface in the solar system. The moon creates a ring of its own as it orbits Saturn—its spray of icy particles spreads out into the space around its orbit, circling the planet to form Saturn’s E ring.
What is mind-blowing about Europa's subsurface ocean?
Europa's subsurface ocean might contain more than twice as much water as Earth
Callisto doesn't have rings, does Callisto have potential for life?
There is evidence of a subsurface ocean on Callisto, putting Callisto on the list of possible places where life could exist beyond Earth.
... makes the first recorded observations of Io and three more moons orbiting Jupiter.
a) Galileo Galilei c) Giovanni Domenico Cassini
b) Johannes Kepler d) Robert Hooke
On December 8, 1610, Galileo Galilei makes the first recorded observations of Io and three more moons orbiting Jupiter.
Does our Moon have an atmosphere?
Our Moon has very, very little atmosphere. One source of the lunar atmosphere is outgassing- the release of gases such as radon and helium resulting from radioactive decay within the crust and mantle. Another important source is the bombardment of the lunar surface by micrometeorites, the solar wind, and sunlight, in a process known as sputtering.
Titan(satellite of Saturn)
Titan’s air is dense enough that you could walk around without a spacesuit. But you’d need an oxygen mask and protection from the bitter cold.
What is so unique and significant about Enceladus?
In 2005, NASA’s Cassini spacecraft discovered that icy water particles and gas gush from the moon’s surface at approximately 800 miles per hour (400 meters per second). The eruptions appear to be continuous, generating an enormous halo of fine ice dust around Enceladus, which supplies material to Saturn's E-ring. Only a small fraction of the material ends up in the ring, however, with most of it falling like snow back to the moon’s surface, which helps keep Enceladus bright white.
