Transcript of Space [Science]
Many people THINK the big dipper is a constellation but, in fact, it is an asterism [as-tuh-riz-uhm]. An asterism is a pattern of stars in the sky which is not one of the official 88 constellations; they are also composed of stars which are not physically related to each other and can be far distances apart. An asterism can be composed of stars from one or more constellations – in the case of the Big Dipper, it is composed entirely of the seven brightest stars in the Ursa Major (Great Bear) constellation. DID YOU KNOW COLD WELDING
If two pieces of metal touch in space, they become permanently stuck together. This may sound unbelievable, but it is true. Two pieces of metal without any coating on them will form in to one piece. This doesn’t happen on earth because the atmosphere puts a layer of oxidized material between the surfaces. This might seem like it would be a big problem on the space station but as most tools used there have come from earth, they are already coated with material. In fact, the only evidence of this seen so far has been in experiments designed to provoke the reaction. This process is called cold welding. THE REASON I SHOWED THESE IS BECAUSE I FOUND A WEBSITE THAT HAD THE TOP TEN INTERESTING FACTS ABOUT SPACE AND I FOUND THESE THE MOST INTERESTING VIDEOS THIS IS THE SUN THIS IS MERCURY THIS IS VENUS FAREWELL OLD FRIEND!
The moon is drifting away from Earth. Every year the moon moves about 3.8cm further away from the Earth. This is caused by tidal effects. The earth is slowing in rotation by about 0.002 seconds per day per century. Scientists do not know how the moon was created, but the generally accepted theory suggests that a large Mars sized object hit the earth causing the Moon to splinter off. THIS IS EARTH THIS IS MARS THIS IS JUPITER THIS IS THE ASTEROID BELT THIS IS SATURN THIS IS URANUS THIS IS NEPTUNE THIS IS A COMET THIS IS OUR MOON THESE ARE BLACK HOLES THANK YOU... http://listverse.com/2007/11/13/top-10-cool-facts-about-space/ SPACE EXPLORATION http://www.google.ca/imghp?hl=en&tab=wi BY JAZZZY
HOPE YOU LIKED IT IF NOT I DO NOT LIKE YOU NOW AINT THAT CUTE Now here is just a fun little video I found on youtube! Now that I did not know. THE SUN
The Sun is one out of billions of stars.
The Sun is the closest star to Earth.
The Sun’s diameter is around 870,000 miles wide.
You Won’t Go Blind Looking at the Sun.
The temperature at the surface of the sun is around 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the sun inward towards the very hot center of the sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
The sun is made up of hydrogen, Carbon, nitrogen, oxygen, neon, iron, silicon, magnesium and sulfur.
About 1.3 million Earths can fit in the Sun. MERCYRY
• Size: Mercury is 4,900 km
•Temperature: Mercury's Maximum Temperature 465°C (870°F)
Mercury's Minimum Temperature -184°C (-300°F)
•Made of: dense iron core that comprises the majority of the planet with a silicate mantle and crust VENUS
• Size: Venus 12,100 km
• Temperature: Venus' Average Temperature 449°C (850°F)
• Made of: Probably has a mostly nickel and iron interior, though this is unproven because of difficulties in collecting data from the planet. This is assumption is based on Venus' similarities to Earth. Its atmosphere is made almost entirely (around 95%) of Carbon Dioxide. EARTH
•Size: around over 40,000km in circumference, and over 500 million km squared in terms of surface area.
•Temperature: There is no accurate and consistent single temperature of the surface of the Earth. The temperature varies moment to moment, and from one point to another - and from century to century. However, if you averaged over space over the course of a year, the average temperature would be about 16 degrees Celsius
•Landscape: Canyons, Caves, Coastlines, Mountains, Oceans, Plateaus, Plains, and Valleys.
•Made of: Composed mostly of iron (roughly 30%, largely concentrated in the core), oxygen (around 30%) and magnesium (around 14%). MARS
•Size: Mars 6,800 km
•Temperature: Mars's Maximum Temperature 36°C (98°F)
Mars's Minimum Temperature -123°C (-190°F)
•Made of: Like the rest of the inner planets, made mostly of iron, with around 16% sulfur in the core and a silicate mantle. JUPITER
•Size: Jupiter 143,000 km
•Temperature: Jupiter's Average Temperature -153°C (-244°F)
•Made of: 90% Hydrogen and 10% Helium (75%/25% by weight). It is speculated to have a rocky core, but the pressures that far into the planet prevent testing at this point in time. The main bulk of the planet probably consists of liquid metallic hydrogen SATURN
• Size: Saturn 125,000 km
• Temperature: Saturn's Average Temperature -184°C (-300°F)
• Made of: Roughly similar percentages to Jupiter, but its interior is hot and gives off more radiation than it receives from the Sun. Why is still open to speculation. URANUS
•Size: Uranus 51,100 km
•Temperature: Uranus' Maximum Temperature -184°C (-300°F)
•Made of: atmosphere is 83% hydrogen, but this is only 15% of the planet's total make up. Primarily, it is made of rock and ice (ice usually being a mixture of water, methane and ammonia). NEPTUNE
• Size: Neptune 49,500 km
• Temperature: Neptune's Average Temperature -223°C (-370°F)
• Made of: Also made up mostly of rock and ice, with only around 15% hydrogen. THE INNER PLANETS
The inner planets are Mercury, Venus, Earth, Mars.
Mercury is hot but it might have ice on it.
Scientists are sure that there is ice on mars
Venus is the hottest planet.
Earth’s magnetic field protects it from diverting harmful radiation from the Sun.
The inner planets (Mercury, Venus, Earth, and Mars) are made primarily of rock.
For more info, this is what the inner planets are also made of, rock, minerals, and metals.
Mercury has a wrinkly crust THE OUTTER PLANETS
• The outer planets are Jupiter, Saturn, Uranus, Neptune.
• Jupiter is the fastest rotating planet
• Views of Saturn’s rings are constantly changing.
• Uranus is flipped over on its side
• The coldest planet in our solar system is Uranus.
• The outer of the planets are made mostly of gases like hydrogen, helium and nitrogen.
• The Gas Giants - Jupiter and Saturn are composed of mainly hydrogen and helium.
• The Ice Giants - Uranus and Neptune are composed of hydrogen and helium but have much more methane and ices.
• THE MOONS
The planet Jupiter has the most moons 63 moons
The planet Saturn has the 2nd most amount of planets 62 moons
The moon is made up of, 42% oxygen,21% silicon,13% iron,8% calcium,7% aluminium,6% magnesium,3% other elements.
These are the 7 largest moons in the solar system:
1. Ganymede - Jupiter
2. Titan - Saturn
3. Callisto - Jupiter
4. Io - Jupiter
5. Moon - Earth
6. Europa - Jupiter
7. Triton - Neptune BLACK HOLES
Black holes emit x-ray radiation and get smaller and smaller until they disappear, or "evaporate".
The gravity around the "hole" of a black hole is so strong that NOTHING can make its way back out after a critical distance.
Most black holes are formed from the death of large stars (larger than the sun)
Even light cannot travel back out of a black hole. DWARF PLANETS
• With a diameter of about 975x909 km
• Ceres has self-gravity
• Ceres is nearly spherical in shape
• Ceres' surface has a large dark spot
• Ceres has a rocky core, an icy mantle that is between 60 to 120 km thick, and a thin dusty surface.
• Eris has a radius of about 1,300 km - giving a diameter of about 2,600 km.
• Eris, is the most massive known dwarf planet
• Eris has an orbital period of 557 years
• Pluto's diameter about 2,274 kilometers.
• Pluto is thought to be made of mostly ice. It probably also has a small rocky core which might contain some metals.
• The ice covering Pluto reflects a lot of sunlight making it appear brighter than it would if it had been covered with a darker rocky material.
• The ice on the surface of Pluto is made of frozen nitrogen, methane and carbon monoxide
• Pluto is a dirty brown color
• Makemake appears red to the human eye.
• Makemake has a radius of about 750 km
• Makemake is very, very cold. The temperature there is about minus 240° C (-406° F)
• Haumea has a glaze of ice over the surface.
• Haumea is one of the strangest known objects in the solar system. It is a big across as Pluto, but shaped like a cigar. Or perhaps like a football [American-style]. Or, most accurately, a football that has too little air in it and has been stepped on. It spins end over end every 4 hours like a football that has been kicked. It appears to be made almost entirely of rock, but with a glaze of ice over the surface. It is surrounded by two tiny satellites .
• Everything that we know about this body appears to tell us that in its past another object slammed into it at high speed and cracked it into pieces which flew all around the outer solar system and left what we see today.
• By looking at sunlight reflected from the surface of Haumea we have found, however, that the surface appears to be pure ice. It seems that Haumea is a large rocky body with a thin film of ice. A cross-section would look something like this: PHASES OF THE MOON
•The phases of the moon are new moon, waxing crescent, 1st quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.
•The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon.
•The phases of the moon work in a cycle starting with the new moon
•There are eight phases of the moon COMETS
• At the center of a comet is the NUCLEUS, which is typically only about 1 to 10 miles across
• As the nucleus moves closer and closer to the Sun, it gets warmer and warmer, which causes its ices to evaporate. When the ices evaporate, they drag DUST particles off of the surface of the comet. Sunlight reflecting off of these dust particles produces a COMA, which is primarily what you see when you look at a comet.
• The dust particles leaving the nucleus are pushed by light from the Sun into a DUST TAIL. The gas molecules (like water, carbon monoxide, and carbon dioxide) that evaporated from the ices are ionized by sunlight (the sunlight tears off one of their electrons) and are pushed by the solar wind into an ION TAIL. ASTEROIDS
Asteroids are essentially chunks of rock that measure in size from a few feet to several miles in diameter
The largest asteroid, Ceres, is about 590 miles
Like most asteroids, it lies in the asteroid belt between Mars and Jupiter. STARS
• formed initially from gas and dust. They are composed mainly of the hydrogen gas
• very hot and give off huge amounts of energy in the form of heat and light.
• Have a life-span of about 10 billion years, after which they will cease to exist.
• Are very far away from Earth. The closest Star is about 23.5 trillion miles away.
• Go through many stages in their lifetime. Some of the names for these stages are Red Giant, Planetary Nebulae, White Dwarf, Neutron and even Black Holes.
• A Star is a gigantic, glowing ball of plasma.
• Stars are first formed as clouds of dust and gas.
• Stars give off a tremendous amount of energy in the form of light and heat
• Most stars are between 1 billion and 10 billion years old.
• I have a video
• The seasons are
Summer,Fall, Winter, and Spring. Eclipses
• A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun's rays from striking the moon.
• A solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially covers the Sun as viewed from some locations on Earth.
• A Solar eclipse always occurs two weeks before or after a lunar eclipse.
• Lunar eclipses can only occur during a full moon. Solar eclipses can only occur during a new moon.
• Eclipses very often occur in threes, alternating lunar, solar and lunar.
• The maximum time a lunar eclipse can last is 3 hours and 40 minutes. The maximum time for a total solar eclipse is 7 minutes and 40 seconds.
• Lunar eclipses can occur up to 3 times a year. Solar eclipses can occur at least 2 and no more than 5 times a year.
• Lunar eclipses are visible over an entire hemisphere. Solar eclipses are visible in a narrow path a maximum of 167 miles wide.
• The cycle of eclipses repeats every 18.6 years called the saros.
• The eclipse shadow moves at 2,000 mph at the Earth's poles and 1,000 mph at the Earth's equator. 1. Q: What is a physical characteristic?
A: The physical characteristics of a landform or of terrain landscape on the Earth (excluding man-made things) would include mountains, valleys or canyons, despair and the like. Rock, sand, dirt, dust or combinations of these surface cover features might be included. Also a mass, size, tempature, landscape and what it is made of. Physical Characteristics is a landform on the surface that characterizes an area.
2. Q: What does major component mean? A: An element or part of something larger.
3. Q: What are the major components of the solar system?
A: The Solar System may be divided by its components into three major components the inner system, the near outer system, and the far outer system like the planets Ya this is kind of what the Solar System would look like from far out This is a video tha you will see right away but what it is about is how the seasons work and how they come!
