00:00Are you ready to test your knowledge of the universe?
00:03We have 40 questions for you.
00:05Let's see how long you can last.
00:08Let's start with the easy level.
00:10Can you guess what celestial body it is from this photo?
00:22With its famous rings, of course it's Saturn.
00:25What force keeps us on the ground?
00:28Magnetism, gravity or friction?
00:37It's gravity.
00:38The same force that dropped an apple on Newton's head.
00:42Is the moon an asteroid, a satellite or a planet?
00:53The moon is a natural satellite of the Earth.
00:57Which star is the closest to our planet?
00:59The polar star, Alpha Centauri or the sun?
01:09Well, it would be strange if it wasn't the sun.
01:13Pluto is a dwarf planet. Is it true or false?
01:16Well, it's absolutely true.
01:25The poor Pluto was expelled from the family of the main planets
01:29but joined its own dwarf planet family in our solar system.
01:33Which is the largest planet in our solar system?
01:36Jupiter, Pluto or the Earth?
01:40It's Jupiter, the gas giant.
01:43Which planet is known as Red Planet?
01:46Venus, Mars or Jupiter?
01:55It's Mars.
01:56The NASA Curiosity rover showed us all these fabulous red-orange desserts.
02:01Wait a minute.
02:02I meant these desserts.
02:04The sun is a planet, a comet or a star?

03:59Make a wish.
04:01What is the smallest planet in our solar system?
04:04Venus, Mercury or Mars?
04:13The answer is Mercury.
04:15Remember that Pluto is only one dwarf planet.
04:19How many planets are there in our solar system?
04:22Take the time to count.
04:30We have 8 main planets.
04:32Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
04:39Who was the first person to walk on the moon?
04:42Jeff Bezos, Neil Armstrong or Elon Musk?
04:51Neil Armstrong, of course.
04:53He is the only astronaut on the list.
04:57What is the name of our galaxy?
04:59The Milky Way, Andromeda Galaxy or the Steel Way?
05:08It is the Milky Way, like the Milky Way chocolates.
05:11Andromeda Galaxy is our closest neighbor.
05:14Man has already walked on Mars.
05:16Is it true or false?
05:27The answer is false.
05:28Only robots have already been on Mars.
05:31But NASA thinks that the first human mission will take place in 2030.
05:37Is Saturn a gas planet, a telluric planet or a dwarf planet?
05:49Saturn is a gas giant, just like Jupiter.
05:52They are the largest planets in our solar system.
05:56The Earth rotates on its own axis.
05:58Is it true or false?
06:08It is true.
06:09The Earth rotates on itself while revolving around the Sun.
06:12That's why we have days and nights.
06:15This level was a little more difficult.
06:17Can you follow so far?
06:19Prepare for the difficult level.
06:22What is the name of this object?
06:26It is a telescope.
06:28More precisely, the James Webb telescope.
06:30It is in orbit in space rather than on Earth.
06:34Which of these planets has the most moons?
06:36Saturn, Earth or Mars?
06:46While we only have one moon and Mars has one moon,
06:50which planet has the most moons?
06:56Mars has two, Saturn has 146.
06:59All this because of its colossal size and its extreme gravity.
07:04Which planet is the farthest from the Sun?
07:06Uranus, Neptune or Jupiter?
07:16It's Neptune.
07:17We mentioned it by counting the number of planets.
07:19And we counted them in order.
07:22How long does it take for the Sun to reach the Earth?
07:26Remember that light also travels at a certain speed.
07:298 minutes, 24 hours or 1 second?
07:32The answer is 8 minutes and 20 seconds.
07:35The speed of light is 300,000 km per second.
07:39What is the warmest color for a star?
07:42Yellow, orange or blue-white?
07:52The answer is surprisingly blue or blue-white.
07:55It's a bit counterintuitive, isn't it?
07:58What is the true color of the Sun?
08:00White, yellow or red?
08:10The answer is white.
08:11It seems logical because we know that white light,
08:14which comes from the Sun, is decomposed in all colors.
08:17So we only see the Sun in yellow because the atmosphere filters certain colors?
08:23The Earth has the most volcanoes in our solar system.
08:26True or false?
08:35It's false.
08:36Venus is the one with the most volcanoes.
08:38It's actually the most toxic and infernal planet in our solar system.
08:43What is the name of the galaxy closest to the Milky Way?
08:46If you have watched this video carefully, you will find the answer.
08:56It's the galaxy of Andromeda.
08:58But although it is our closest neighbor,
09:00it is still 2.5 million light years away.
09:05What is the coldest planet in our solar system?
09:08Uranus, Neptune or Pluto?
09:16It's Uranus.
09:17Pluto is not a planet.
09:19And we might think it should be Neptune,
09:21since it is the furthest from the Sun.
09:23Especially since the average temperatures on Neptune are colder.
09:27Minus 201 degrees Celsius.
09:29But the lowest temperature, about minus 224 degrees Celsius,
09:33was recorded on Uranus.
09:35This place can therefore also be considered as the coldest planet.
09:40What planet has the most moons?
09:46Saturn
09:51We have already talked about it.
09:53It's Saturn, with its incredible number of satellites.
09:57Phew, give yourself a good slap on the shoulder.
09:59And finally, let's attack the impossible level.
10:02Good luck to you.
10:04What is the maximum speed of light in space?
10:071,600,000 km per second,
10:09300,000 km per second
10:11or 67 km per second?
10:14If you don't know, try to guess.
10:16It's 300,000 km per second.
10:19And the distance that light travels in a year of travel
10:22is what we call a year of light.
10:26On which planet can you jump the highest?
10:28Earth, Venus or Mercury?
10:37It's Mercury.
10:38It's the smallest and lightest planet in our solar system.
10:42So gravity is very weak there.
10:45What is the main component of the sun?
10:47Oxygen, hydrogen or nitrogen?
10:57The answer is hydrogen.
10:59It is what constitutes the majority of stars.
11:01And it is the most common element in the entire universe.
11:05What is the approximate age of the universe?
11:073 billion years, 13.8 billion years or 100 billion years?
11:16It's 13.8 billion years.
11:18And our sun, as for him, is about 4.6 billion years old.
11:23And I wasn't even born at that time.
11:26Guess the name of this scientist.
11:38This is a portrait of Isaac Newton.
11:42What is the warmest planet in our solar system?
11:45Venus, Mercury or Earth?
11:53You might think it's Mercury because it's the closest to the sun.
11:57But in reality, it's Venus.
11:59As we said, it's the most toxic and volcanic planet we have.
12:03What type of star does our sun correspond to?
12:06Red giant, white dwarf or yellow dwarf?
12:16Although the sun's light is white, the sun is a yellow dwarf.
12:20One of the coldest types of stars.
12:23There is a black hole in the middle of most of the big galaxies.
12:26True or false?
12:29False
12:35It's actually true.
12:36Although it doesn't suck up the entire galaxy,
12:39supermassive black holes are generally located in their center.
12:44What phenomenon causes the auroras?
12:46Earth's magnetic field, cosmic rays or black holes?
12:50Earth's magnetic field
12:56It's the Earth's magnetic field.
12:58When the particles of the sun reach the Earth and interact with its atmosphere,
13:02they release a brilliant energy, which creates these beautiful colors in the sky.
13:06Now, a little math.
13:08If the speed of light is 300,000 km per second,
13:12and it reaches the Earth in 8 minutes,
13:14what is the distance between the Earth and the sun?
13:17Bonus points for those who calculate this by heart.
13:23The answer is about 150 million km.
13:27Have you managed to play the impossible level?
13:30Very well, let's see if you are smart enough to answer this last bonus question.
13:35If you were standing on the moon and the Earth was directly above you in the lunar sky,
13:40how often would you see the Earth rise or set?
13:43Think about it.
13:47The answer is...
13:49Never.
13:50The moon is in synchronous rotation with the Earth,
13:53which means that we always see it on the same side,
13:56while the other is always hidden.
13:58Thus, the Earth would remain almost fixed in the lunar sky permanently.
14:04How many good answers did you get?
14:06Write it in the comments below.
