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?

02:14The sun is 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.
