00:00Hey friends! Wondering where I am right?
00:03Well, I am in space.
00:06And do you know what that is?
00:08That is our galaxy.
00:10And it's called the Milky Way.
00:13Do you see that?
00:15That bright light is our solar system.
00:19And it's called the Milky Way.
00:21And it's called the Milky Way.
00:23And it's called the Milky Way.
00:26And it's called the Milky Way.
00:28That bright light is our solar system.
00:31That's where we live.
00:33Come, let's take a closer look at our solar system.
00:37Zoom in!
00:39This is how our solar system looks like.
00:44With planets revolving around the sun.
00:48The sun is the main source of light for all the planets.
00:52Our solar system has 8 major planets.
00:58Mercury.
01:00Mercury is the closest planet to the sun.
01:03A year in Mercury is 88 days long.
01:07And you know what?
01:09You will see Mercury from Earth in the year 2016.
01:14Venus.
01:16Venus is the second planet from the sun.
01:18And it is the hottest planet in the solar system.
01:22That's because it has high amount of Carbon Dioxide.
01:26Which traps heat inside it.
01:29Earth.
01:32This is my favourite planet.
01:34For obvious reasons of course.
01:36Earth is a unique planet with suitable climatic condition.
01:40Landforms and water bodies.
01:42Which support life in all forms.
01:46Moon is the natural satellite of Earth.
01:50Mars.
01:52Mars is often known as the Red Planet.
01:54Because of its reddish appearance, it is home to some of the largest dust storms.
02:00Which can continue for months and cover the entire planet.
02:12Jupiter.
02:14Jupiter is the largest planet of our solar system.
02:18It also has 4 moons.
02:21One day in Jupiter is just about 9 hours 55 minutes.
02:26Making it the shortest day of all planets.
02:29Saturn.
02:31There are about 150 frozen moons around Saturn.
02:36The largest one is called Titan.
02:39This planet has beautiful rings around it.
02:42Made of dust and ice.
02:44Uranus.
02:47Uranus is a very very cold planet.
02:50With temperatures dropping to about minus 224 degrees Celsius.
02:57It takes about 84 Earth years to revolve around the Sun.
03:02Out of which it gets direct sunlight for 42 years.
03:06And the rest remain in darkness.
03:09Neptune.
03:11Neptune takes about 165 Earth years to revolve around the Sun.
03:16It is also known as the Ice Giant.
03:20And it has about 14 moons.
03:26Trivia Time.
03:28Did you know that we also have 5 dwarf planets in our solar system?
03:32Ceres.
03:34Pluto.
03:37Eris.
03:39Makemake.
03:41And Haumea.
03:43Jupiter's moon Ganymede has more water than the Earth.
03:48Whoa! That's so much information for today.
03:52I am tired now.
03:55So this is me zooming out.
03:57Tune in next time for some more fun facts.
04:09Hey friends.
04:11Are you wondering where I am?
04:13Well, I am in space.
04:15But hey, I have travelled 4.6 billion years back in time.
04:22Exactly when our solar system was formed.
04:25Well, since we don't have that much time.
04:28Let me fast forward the process and tell you about the formation of the solar system.
04:33Zoom in.
04:36It is believed that our solar system was formed..
04:39..when a cloud of dust and gas was disturbed by an explosion of a nearby star..
04:45..called the Supernova.
04:48The star exploded with a bang and its effect travelled in waves all around.
04:54These waves squeezed the cloud of dust and gas resulting in its collapse.
05:01All the little pieces of matter that started out running away from each other..
05:06..got pulled back together by gravity.
05:09Soon the cloud began spinning at a tremendous speed.
05:13And there it was, a beautiful solar nebula in the making.
05:19Just for some extra information.
05:22A solar nebula is a large cloud of gas and dust..
05:26..from which the sun, planets and other solar system bodies..
05:30..like asteroids, meteors and moons were formed.
05:35Okay, so let's now continue from where we left off.
05:38When the spinning slowed down, the centre of the solar nebula became hotter and denser..
05:44..which was surrounded by a disk of gas and dust that was cool at the edges.
05:50At the heart of the nebula, there was a ball of hydrogen gas..
05:55..whose pressure and temperature became quite huge..
05:58..and the particles began to fuse together.
06:01There it was, a new powerful star coming into being.
06:06Yes, that was our sun, shining like a fiery ball.
06:11There were infinite number of particles that began to stick together and form clumps.
06:19Some clumps got bigger and bigger and bigger..
06:23..forming planets and moons.
06:26Aha! So now you know how the planets were born, isn't it?
06:31It is also believed that since the centre of the solar nebula was hot..
06:37..it was easier for some planets to form in there, like..
06:41..Mercury, Venus, Earth, Mars and Jupiter.
06:49The rest of the cold planets like Saturn, Neptune, Uranus etc..
06:56..were formed at the edges.
06:59Trivia Time!
07:01Did you know that the sun takes up 99% of the solar system's mass?
07:07This means that we are technically living inside the atmosphere of the sun.
07:13The rocks that belong to Mars have been found on Earth.
07:18And guess what, we didn't bring them here.
07:22Does that make you raise your eyebrows?
07:28Time for me to get back to Earth.
07:30Tune in next time for more fun facts.
07:34This is me, zooming out.
07:40Oh! Whose birthday is it, little kitty?
07:44Son, whose is Sunday?
07:50Well, unfortunately we don't know the exact date of the sun's birthday.
07:56However, we do know something about its birth and how it came into existence.
08:02So in today's episode, let us explore the creation of our beloved sun..
08:08..and answer a burning hot question.
08:12How was the sun formed? Zoom in!
08:17There are billions of stars in our galaxy.
08:20But the great glorious sun holds a special place in our lives.
08:25That's because its gravity keeps the solar system together..
08:30..holding everything from the biggest planets..
08:33..to the smallest particles of debris in its orbit.
08:37Not only that, the connection between the sun and Earth..
08:41..drive the seasons, ocean currents, weather..
08:46..radiation bells and auroras.
08:50But the vital question is, how did our sun come into existence?
08:58Well, it all started 4.5 billion years ago..
09:02..in the Milky Way galaxies, Orion and Neptune.
09:06In those galaxies, Orion's spur, when waves of energy traveling through the space..
09:13..pressed together the clouds of gas and dust called a solar nebula.
09:19These clouds mainly consisted of the gases like Hydrogen and Helium.
09:25But some of it was made up of the remaining remnants of dead stars.
09:31Then, as the nebula collapsed because of its gravity..
09:37..most of the material was pulled toward the center as it began to spin faster..
09:43..causing the cloud to flatten into a disk.
09:46And in the center of this disk formation, the material continued to clump together..
09:53..as the matter condensed into a burning ball of gas to form a protostar.
10:00Then, over the next tens of millions of years..
10:04..the temperature and pressure of the material inside increased..
10:09..jump-starting the fusion of Hydrogen that made the sun we know today.
10:16Today, with a radius of 4,32,168.6 miles..
10:24..our sun is the largest object in our solar system.
10:29It is so big that it would take 3,32,946 Earths to match the mass of the sun..
10:39..and can fit all 8 planets inside it nearly 600 times.
10:47The sun can be divided into 6 layers.
10:50Starting from the Corona, next comes the Chromosphere..
10:56..then the Photosphere, followed by the Convective Zone, Radiative Zone..
11:02..and finally the Core.
11:05In terms of atom count, the sun is made up of 91% Hydrogen that acts as its fuel..
11:13..8.9% Helium and 0.1% heavier elements like Nitrogen and Carbon.
11:22The temperature at the surface of the sun is about 5600 Celsius..
11:29..which rises as we go inward towards the center of the sun..
11:34..where it reaches around 15 million Celsius.
11:39Now, that's really hot!
11:42But here's a thing, my friends.
11:44Like all stars, the sun will someday run out of energy.
11:49Yes, scientists predict that the sun is a little less than half way through its lifetime..
11:57..and will last another 6.5 billion years.
12:01After that, it will swell to become a red giant.
12:06Eventually, it will shed its outer layers..
12:09..and the remaining core will collapse to become a white dwarf.
12:14Slowly, the white dwarf will fade and will enter its final phase as a dim, cool object..
12:23..known as a Black Dwarf.
12:26Did you know, the sun is the closest star to our planet?
12:30Yes, the sun is 93 million miles away from the Earth.
12:37Hope you learned something new today.
12:40Until next time, it's me Dr. Binocs, Zooming out!
12:55Ah, the great glorious moon!
12:58I hope someday we'll learn about its great glorious past.
13:03Past?
13:05Yes, little kitty.
13:07Even after all these years, scientists are still unsure about the moon's exact origin..
13:14..and all we have is a few theories.
13:18Oh, so share them.
13:21Haha, as you say my curious cat.
13:26Hey friends, I know you are equally curious to learn about the moon's backstory.
13:33So, in today's episode, let us shed some light..
13:38..on the best theories we have on the formation of the moon.
13:42Zoom in!
13:45We learned so much about our natural satellite in your previous videos.
13:50Right from its different phases to its eclipse..
13:54..and even explored the possibilities of what will happen if the moon disappeared.
14:01So, I request you to please check these videos once.
14:06The links are in the description below.
14:10Now, when it comes to the moon's formation..
14:13..the Earth plays a significant role in its birth.
14:16Yes, in its 4.5 billion years of lifespan..
14:21..planet Earth has seen several asteroids shooting towards it with great force.
14:28Some of them collided with the Earth and got destroyed.
14:32While many of them hit the surface creating bowl-shaped depressions called craters.
14:39And most of them missed the hit and kept flying ahead in space.
14:46Though most traces of the Earth's past have long since been destroyed..
14:52..but we can find clues for most of it.
14:55And that's why scientists have come up with different theories about space formation..
15:02..including the formation of the moon.
15:05So, let us have a look at them one after the other.
15:11Although there are various theories revolving around the formation of the moon..
15:16..the following few are the most concrete and popular ones.
15:21Starting with the Capture Theory.
15:26According to this theory, the moon was formed elsewhere in the solar system..
15:31..and was wandering in space aimlessly, unaware of its future.
15:38But when it came closer to our Earth, it was captured by its gravity.
15:44And since, it is still stuck in the gravitational field of our planet.
15:51The next popular theory is called the Accretion Theory.
15:57This theory suggests that the moon was created along with the Earth during its formation.
16:04But this notion died out quickly as it could not define the speed of the moon.
16:13Another popular theory is called the Fission Scenario.
16:19According to this theory, the Earth was spinning so fast around its axis..
16:25..that a small part of it broke away and began revolving around the planet.
16:31But again, we didn't have much evidence to prove this idea.
16:36And soon we came up with the most concrete and widely accepted theory..
16:43..which is the Giant Impact Theory.
16:49Yes, according to the Giant Impact Theory, millions of years ago..
16:54..even before the Earth and the moon, there existed Proto-Earth and Theia..
17:00..a planet almost the size of Mars.
17:04One day, when these two bodies collided with each other..
17:09..and due to the explosion of heat, the Proto-Earth and Theia..
17:14..melted only to form as a new giant body that we today know as the Planet Earth.
17:23Only the small part of the two planets collected near the Earth's orbit..
17:29..which with time formed into the moon that revolves around our planet.
17:38TRIVIA TIME!
17:40Did you know, the size of our moon is almost equivalent..
17:45..to that of the size of the planet Mars?
17:49Also, you won't believe it, but the moon's surface is actually dark.
17:56Hope you learned something new today.
17:59Until next time, it's me, Dr. Binocs, Zooming out!
18:05Let's go home, kitty.
18:07Hope someday, someone will find the real story behind the moon's formation.
18:16Never mind.
18:26What are you making, little kitty?
18:31For that, you'll need more than just clay.
18:35Bye!
18:37That's an excellent question.
18:40Hey friends, in today's episode, let us see the process..
18:44..behind the creation of our beloved planet and answer a crucial question.
18:50How did the Earth form?
18:52Zoom in!
18:55Planet Earth, a giant mass of water and mud revolving in space..
19:00..and the only known home sweet home formed just for us.
19:05As it gives us food to eat, water to drink and air to breathe..
19:11..making it a perfect breeding ground for life to evolve.
19:16But, have you ever wondered, how did this giant planet come into existence in the first place?
19:23I'm sure you did.
19:25So, let me tell you this astonishing story of the Earth's formation.
19:31Well, it all began a long time ago, which is about 15 billion years ago..
19:38..when the whole universe was inside a tiny bubble called the Cosmic Egg.
19:44Then about 13.8 billion years ago, the little ball bubble began heating up..
19:51..and generating energy until it finally exploded with a bang.
19:56Today, we call this massive explosion, the Big Bang.
20:02You can check our video on the same, the link is in the description.
20:07Then about 4.5 billion years ago, when the universe began to cool down a bit..
20:15..and settled into its current layout, everything started to spin, forming mighty wind and gravity.
20:24And over time, one such gravitational force from the remnant of a dead star..
20:31..started pulling the giant dirty gas cloud.
20:35This cloud got denser and denser in its center and formed an accretion disk.
20:45Then in the next 10 to 20 million years, other small particles of dust, rock and gas..
20:52..started sticking together, creating larger objects.
20:57Until it became a sphere and large enough to be called a planet by today's standard.
21:03And Young Earth was formed.
21:06At this point, the Earth's surface temperature was a burning mess..
21:12..with seas of lava and a poisonous atmosphere.
21:16Not only that, various comets, asteroids and other cosmic elements..
21:21..constantly attacked it from all sides, making it boil more and more.
21:30But soon, things took a dramatic turn and the cosmic attack reduced.
21:36And so, as the temperature of the Earth cooled down..
21:40..water from the inside of the Earth rose to the surface, formed steam..
21:46..and rained back on the ground to form oceans.
21:51Even other meteors brought more water to our land in the form of ice.
21:57So gradually, the Earth cooled down and the surface formed a thin crust.
22:04Meanwhile, the volcanoes on the ocean's bed blew magma to the top..
22:10..which eventually cooled down to form volcanic islands..
22:15..that joined together to create a single giant continent called Pangaea.
22:21And inside the Earth, the hot rock continued to move around..
22:26..moving the crust below and breaking it apart through a process called plate tectonics.
22:33We have a separate video dedicated wholly to this topic.
22:38Please check the link below.
22:40And as the Earth's crust moved around, Pangaea broke apart..
22:45..and its pieces drifted away to create the continents we see today.
22:51And modern Earth took its form.
22:54A place we all can proudly call home.
22:59Trivia Time!
23:01Did you know, April 22nd every year is observed as Earth Day?
23:08Yes, it was first organized in 1970 to promote ecology..
23:13..and raise awareness of the growing problems of air, water and soil pollution.
23:19So, please do your bit and share this video with friends and family.
23:27Hope you learned something new in today's episode.
23:31Until next time, it's me, Dr. Binox, Zooming out!
23:42Ah, never mind.
23:50Are you ready for the ultimate million dollar question, little kitty?
23:55Now, tell me, which is the smallest planet in our solar system?
24:02Pluto!
24:04Well, I'm sorry kitty, but Pluto is the wrong answer.
24:10Why?
24:12Well, that's undoubtedly a million dollar question.
24:16Hey friends, a lot of us grew up reading about the old nine planets.
24:21But later, Pluto was delisted from its status, generating mass confusion about its identity.
24:30So, in today's episode, let us explore the reason behind Pluto's planetary fate..
24:36..and answer a fascinating question.
24:40Why is Pluto not a planet anymore?
24:44Zoom in!
24:46Until the year 2005, every school science book thought us that there are nine planets.
24:55Namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and of course, Pluto.
25:06Which was the smallest amongst all.
25:09This celestial body was discovered in 1930 by an American astronomer, Clyde Tombaugh.
25:17And since then, everything was a smooth sail for students across the world.
25:24But on a warm day in August 2006, few scientists gathered at the International Astronomical Union in Paris..
25:33..and astounded the world by declaring Pluto as not a planet.
25:41After hearing this startling news, the educational unions took notes and changed the matter in the textbooks.
25:49But the vital question is, why did the scientist community take its title of a planet away?
25:57Well, according to IAU, for a celestial body to be a planet, it needs to fulfill three essential criteria.
26:07First, the object should revolve around the Sun.
26:12Second, the object should be spherical in shape.
26:16And thirdly, the area around its orbit should be clear and should not have any equivalent or a bigger celestial body.
26:26Meaning, with the help of its gravity, the planet should clear asteroids and dwarf planets out of its way.
26:34I know what you are thinking, isn't Pluto spherical and revolves around the Sun?
26:40Yes, Pluto does fulfill these two conditions.
26:44But in the late 90s, space scientists found out that it doesn't meet the third criteria..
26:52..as it hasn't cleared the neighborhood objects around its orbit.
26:56Because of which, it can't be called a planet..
27:00..and was downgraded the status of Pluto to that of a dwarf planet.
27:06But Pluto isn't the only one to be called a dwarf planet.
27:11Yes, in the Kuiper belt near Pluto, scientists found two planets..
27:16..namely Homia and Makemake, which were just like Pluto.
27:21Not only that, but in 2005, the explorers also discovered Eris..
27:28..which looked bigger than Pluto itself.
27:31All these newly found space objects acted like Pluto..
27:35..but were nowhere similar to other planets in the solar system.
27:39So that's when the IAU came up with a checklist to help them classify a planet.
27:46And according to it, Pluto and these other planets fit into the first two criteria.
27:52That is, it revolved around the Sun and was spherical.
27:56But they didn't meet the third, which stated that the area surrounding it should be clear.
28:03Hence Pluto was out of team planet and landed on team dwarf planet.
28:11TRIVIA TIME!
28:13Did you know, Venetia Burney, just 11 years old at the time..
28:18..suggested the name Pluto in 1930?
28:21Also, Pluto is the only planet in the solar system with ice volcanoes..
28:27..and an ocean hidden under its icy surface.
28:32Hope you learnt something new in today's episode.
28:36Until next time, it's me Dr. Binocs, Zooming out!
28:42Aw, never mind.
