The Largest Object in the Solar System

By Anupum Pant

On November 6th 1892, after being spotted by a British astronomer Edwin Holmes, comet Holmes was not seen again for several decades. Thus it came to be known as the lost comet. Out of the blue, more than 70 years later, the comet was again seen in the year 1964.

Now it is known that comet Holmes was captured by Jupiter several thousand years ago, and it never went back to the Kuiper belt. It is a Jupiter family comet. Every 6.88 years, the comet orbits the sun.

Even this year, on 27th of March, it was one of the most bright comets of the year. But it was something that happened back in the year 2007 which made it one of the most popular comets in the sky.

For a brief period, comet Holmes, which is also a part of our solar system, became the largest object in the solar system. Yes, even larger than the sun!

On November 9th 2007, the diameter of comet’s coma – a cloudy region surrounding the comet made up of very tiny shiny ice and dust particles – measured about 1.4 million km. The sun’s diameter rounded to the nearest hundred is estimated to be 1.392 million km. Agreed the coma wasn’t as massive as the sun, but the size of it did measure slightly more than the sun at that time.

It indeed is a great achievement to become the largest object in the solar system (for some time) for an object that is just a tiny mass of ice and dust that is only about 3.6 km wide.

That day, the cloud around it erupted due to a mysterious outburst which still puzzles scientists. Such outbursts have been seen in the past too and are thought to have been originated as a result of its collision with a meteor (or probably due to an internal steam eruption).

A Massive 3200 Year Old Tree in a Single Picture

By Anupum Pant

If there’s one place I’d like to visit, it is the part of California where you find giant sequoia trees. The Giant forest is one such grove in the western Sierra Nevada of California. It is home to five of the ten most massive trees on the planet.

With a tree trunk measuring 36.5 feet in diameter, the Giant Sherman in the Giant forest grove, is the largest of the trees in this grove. It is 275 feet tall! (and yet there are taller trees in existence – Hyperion – again in California, which is about 379 feet tall)

While the President tree, 3200 years old, is another one of these Giant sequoia. It has seen hundred generations of humans pass by. Throughout its life it has survived a number of storms, fires, winters, earthquakes, and climate changes. And even today it grows faster than most other trees on the planet, adding one cubic meter of wood every year.

Its trunk measures around 27 feet in diameter.  In height, its topmost point measuring at 247 feet, is slightly shorter than the Giant Sherman. Still, the tree is massive. Its huge branches hold about 2 billion needles (leaves), which is more than any other tree on earth.

It is so huge that until recently it hadn’t been captured in a single photograph (excluding satellite shots and other such smart ideas). A team from National geographic magazine joined scientists to study and photograph the tree.

World’s Largest Building Has a Climate of Its Own

By Anupum Pant

A place where planes like the Boeing 747, 767, 777 and 787 are built, has to be huge. But this Boeing factory in Everett, Washington, home to 30,000 workers (working in 3 shifts), is so huge that the inside of the building has a climate of its own. It is the largest building on Earth. If you get a chance, you must not drop a chance to take the 90-minute tour of this factory (it costs $15 per adult). Here are a few things to note about it…

The size: The volume of this factory is 472 million cubic feet or 13.3 million cubic meters. That is enough to fit the whole Disney land and still be left with a 12 acre place to park the vehicles. In other words, it could fit 800 standard sized hockey rinks. Or it could fit in 75 football fields. Or it can hold about 12 empire state buildings! You get an idea how huge it is, right?

Largest Digital Mural: Being huge comes with its own side effects – another world record. The doors, like the building, are huge too. The factory has 6 doors, where each of them is 82 feet in height and 300-350 feet in width! You could bring in an NFL field (as in, fit the length of it) in through one of these. But what is more interesting about these doors is that they are covered with a 100,000 square feet of digital graphic. This is the largest digital mural in the world – printed by SuperGraphics, Seattle. It took the workers 27 days to install the digital mural.

Small City: Had this place been slightly larger, it could have had enough space to fit in a country – The Vatican city. Still, it isn’t small. The building is like a small city with it’s own fire department, security force, fully equipped medical clinic, electrical substations and water treatment plant. To move around in this little city, the employees use 1,300 bicycles.

Its own Climate? Now, since it is like a small city, it has to have its own climate, right? Yes. When the building was first built, clouds got formed inside and some say it even rained inside (mostly, not true). But rainbows have definitely been seen inside.
The temperature inside the building is controlled by those 1 million bulbs that are used in there. During winters, the bulbs bring warmth and during summers the doors are opened and air circulating fans are switched on to let the fresh Everett breeze come in.

Bonus fact: The network of 26 overhead cranes have about a total of 39 miles of ceiling rails inside the factory!

A Natural Explosion That Knocked 80 Million Trees

By Anupum Pant

In the year 1908 (June 30), a remote part of Siberia experienced something really mysterious and really huge. It was an explosion that took place at about 5-10 km altitude in the air which was estimated to be as powerful as 1000 (or 185 according to NASA) Hiroshima bombs!

No one could ever figure out what really caused it. However, scientists were pretty sure that it was either a huge meteorite of about 100 feet (some say 1000 m) in diameter which crashed into the earth’s atmosphere and disintegrated, or it just bounced off the earth’s atmosphere like a huge skipping stone. Besides the scientific theories, there are a number of other “UFO and alien” stories that have been associated with this event. This was called the Tunguska event.

The sheer size: The explosion was utterly gigantic. So big, that it is still considered to be the most powerful natural explosion in the known history. The shock-waves from the explosion knocked people off their feet, and these people were 40 miles away from where the explosion happened. It wasn’t just people, 80 million trees over an area of 2,150 square kilometres were knocked down in a radial pattern (with trunks pointing away from the epicentre). 80 million! Wow!

It caused a mini earthquake and a NatGeo article says that the lake Checko could have been created due to this impact.

Eyewitness’ account:

Suddenly in the north sky… the sky was split in two, and high above the forest the whole northern part of the sky appeared covered with fire… At that moment there was a bang in the sky and a mighty crash… The crash was followed by a noise like stones falling from the sky, or of guns firing. The earth trembled.
[NASA website]

Had this taken place above a metro city, the city would have been completely levelled by the event. But that is highly unlikely because cities take up a very small fraction of area on the earth’s surface. Moreover, very rarely do such events happen.

What is very likely is that such an event could happen over the part which covers 70% of the earth’s surface – the ocean. Such an event could create a huge Tsunami causing a lot of destruction on land.

Pando – An Organism That Weighs 6 Million KG

By Anupum Pant

Blue whales weigh about 150 tons each. That is a 150,000 kg animal we are talking about! Incredible! It is the largest animal to have ever lived on earth. Yes, bigger than any of the dinosaurs. Just for the perspective, the heart of a blue whale can weigh about 600 kg and is almost the size of a Volkswagen Beetle car. A human can fit in its arteries. But, if you thought no other organism can be heavier than a blue whale, you are in for a surprise.

The heaviest organism we’ve ever found, lives in the Fishlake national forest, Utah. In fact, the organism itself is the forest. This forest is a Vatican-city-sized forest which looks like it has several identical trees in a normal forest. Only what looks like identical trees in a normal forest, is actually a single huge tree.

The absolutely humongous tree is known to have come out of a single seed about 80,000 years back. With time, it went on to spread its roots and has cloned itself by popping out about 47,000 other extant clones.

Since it is a single huge tree, it indeed acts like a single huge tree. When one of the shoots (tree) is in need of nutrients, the interconnected root system makes sure that the tree gets what it needs. Also, these trees transition from winter to spring simultaneously, just like a single huge tree would.

Titin Protein – The Longest Word in English

By Anupum Pant

Background

No, I’m not talking about the fictional character Tintin. It’s Titin I’m talking about. The initial part of it is pronounced almost like Titan, but please do not confuse it with Titan.  Titin is the largest protein molecule ever discovered. Soon you’ll see why it is the largest…

Titin is the short name for an extremely massive protein molecule. The full-length scientific name of this protein molecule contains 189,819 characters and is considered (by some) as the longest word in not just English, but any language.

Others choose to not consider it a word at all. You won’t even find the full scientific name of Titin in any dictionary. According to lexicographers it is only a chemical formula, not a word. Technically, they are right. So, it is not really the longest word in English.

In that case, probably a lung disease called pneumonoultramicroscopicsilicovolcanoconiosis can be considered the largest word. There are 45 letters in it. But my history teacher once told me that floccinaucinihilipilification (meaning, the estimation of something as worthless) was the longest word in English. Well, someone needs to tell me which one it really is. Till then, I’ll consider Titin as the undefeated champion…

What is it?

Titin is a protein found in certain kind of muscle tissues. It is the thing that makes those muscles elastic. For instance, in heart muscles – that expand and contract continuously for decades, without a break. The folded nature of this huge molecule makes it act like a spring – just like a long wire can be coiled into a small spring. The full chemical formula goes like this:

C132983H211861N36149O40883S693

I won’t spam my blog with the full name, but I’ll definitely point you to it. [Full name spelled out]. If you are too lazy to go there, it starts like this:

Methionylthreonylthreonylglutaminylalrylglycylphenylalanylprolylvalylprolyylglycylarginylalanyllysylleucylthreonylglutamylleucylleu…

and ends like this:

partylaspartylleucylthreonylthrnylaspartylvalylglutaminyllysylglutamilthreonylleucylserylleucylglycylasparalaspartylserylalanylthr…

The video: It takes about 233 minutes to pronounce the full chemical name – Yes, a guy tried it out (with video cuts of course). The gentleman pronounces it on camera for you. If you care enough to watch the whole 3 and half hour-long video, you’ll see how the man grows a stubble while pronouncing it. Also, you’ll see the plant dying out. But those are only gimmicks that makes the video funny. I’d like to add that his expression in the end is priceless. You shouldn’t miss that. Here, I’ve attached it for you below:

To use up the same amount of time in a better manner, I suggest that you watch the Bill Nye vs. Ken Ham debate.

World’s Most Powerful Sound Systems Can Kill You

By Anupum Pant

In the past we’ve seen sound systems that used plasma instead of magnets to produce sound. Well, those plasma sound systems were pretty well equipped to kill you, but they would do it in a different manner – by electrocuting you. This one we are talking about today, literally kills you with sound.

LEAF

European Space Agency uses an extra-large speaker that throws extra-big sound at test objects. It is known to recreate the sound that a launcher produces while taking off and travelling through atmosphere. This speaker, known as, the Large European Acoustic Facility (LEAF) in Netherlands, is used by the European Space Agency to test satellite parts.

The Glory: They say that if any person listens to sound playing on this speaker, he/she won’t survive. This is the reason, the most powerful sound system in Europe, is enclosed in a facility that has walls that 17 meters in height, are half a meter thick and are overlaid with a resin on the inner walls that reflects sound & does not let it escape. Also, it has a safety mechanism that doesn’t allow anyone to power it on, if the doors are not shut properly.

Nitrogen is pumped in great amounts through the huge ear-canal-like thing which enables it to produce sounds up to 154 decibel! If you are wondering how loud 154 decibel is, you should check this out – How Loud Can it Get. In short, it is loud enough to rupture your eardrums and probably kill you too.

I came across this equipment first at [PopSci]
More information at [ESA]

So I wondered, if this is the most powerful sound system in Europe, are there more powerful ones elsewhere in the world?
Duh! Yeah. And as expected, it is in USA.

Reverberant Acoustic Test Facility (RATF)

Orion-Integrated-Environmental-TestingThe Orion Integrated Environmental Testing at the NASA Space Power Facility (SPF), a huge facility which looks pretty much like a nuclear power plant from afar, houses several other testing facilities, and the world’s largest space environment simulation chamber, also has the worlds most powerful sound system – The Reverberant Acoustic Test Facility. [Image]

The horns that produce sound here, are also powered by Nitrogen and there are 36 of them. It is able to produce a total sound pressure of 163 dB, which is a lot more than what LEAF can produce (because dB scale is not linear) – About seven times more powerful than standing next to a jet engine or a Formula 1 race car. In here, it is far too easy to kill a full grown man.

There Is No Lake Like The Taal Lake

By Anupum Pant

Geologically this is quite a phenomenon and might get a bit confusing to grasp if you stop paying enough attention. Here we go…

Island in a lake on an island in a lake…

Taal lake is a freshwater lake on the Luzon island of Philippines. Almost at the center of this lake, is an island called the volcano island. At the center of this island is another lake called the main crater lake. And in this lake is a small landmass called the Vulcan point. [map]

Now take a deep breath…in short, it is, Luzon island > Taal lake > Volcano island > Main crater lake > Vulcan Point.

The main crater lake: Even though the crater lake isn’t a very big lake, it is still claimed as the  world’s largest lake on an island (Volcano Island) in a lake (Taal Lake) on an island (Luzon). Of course it is, where else in the whole world would you find a lake on an island in a lake on an island?

Vulcan point: On this world’s largest lake on an island in a lake on an island, is a tiny land mass called the Vulcan Point which is the world’s largest volcano in a lake (Main Crater Lake) on a volcano (Taal Volcano). It isn’t even big enough to support a small house.

Home to Unique Species

But all that is just a part of what is interesting about the Taal lake. Ecologically it is another marvel in a way that it is home to a few species of animals that are found nowhere else on earth. In this lake you’ll find the only varieties of fresh water sardines, sharks and sea snakes.

Reason: This lake was not a lake several thousands of years back. Then, due to volcanic eruptions, it got separated from the sea. Now the only thing that connected this water mass and the sea was Pansipit river. Gradually, several hundreds of years of precipitation converted this lake from a saltwater lake to a freshwater lake. For centuries, animals living here have remained isolated and have evolved into unique species to adapt to this desalination.

Largest Meteorite Left No Crater On Earth

By Anupum Pant

You should know: Meteor vs. Meteoroid vs. Meteorite

Meteor: The streak of light that we see in the sky is “Meteor”. When debris enters earth and gets burned up while entering, it leaves a streak of light. Unlike what is popularly believed, meteor is not the debris itself rather the word “meteor” refers to only the flash of light.

Meteoroid: A meteoroid is a mass that is small – ranging from a kilometer to only a few millimeters in diameter. Most meteoroids that enter the Earth’s atmosphere are so small that they vaporize completely and never reach the planet’s surface.

Meteorite: If the Meteoroid survives and reaches the earth’s surface, it becomes a Meteorite.

Hoba the Meteorite

About 80,000 years back, a ridiculously huge mix of Iron and Nickel entered the earth. It was so large that what was left out of all the burning through the atmosphere, measured 66,000 kg in the end. About half ton of this meteorite has gone to laboratories for research. Even after accounting for losses towards laboratories and vandalism, it is still the largest single mass of natural Iron on the Earth’s surface. It is the largest meteorite ever discovered till date and is called “Hoba”.

This meteorite was discovered by a farmer in Namibia in the year 1920. Since then, due to its mass, it has never been moved. The meteorite and the site has been declared as a national monument by the Namibian government and several tourists visit it every year.

Farmer’s Story: 

One winter as I was hunting at the farm Hoba I noticed a strange rock. I sat down on it. Only its upper part was visible. The rock was black, and all around it was calcareous soil. I scratched the rock with my knife and saw there was a shine beneath the surface. I then chiselled off a piece and took it to the SWA Maatskappy in Grootfontein, whose director established it to be a meteorite.

If that was hardly interesting…

The most puzzling thing about this meteorite is probably not that it belongs to a very rare class of meteorites (Ataxite), but the fact that it has no crater to be seen around it. Normally, a meteorite of this size should have left a crater hundreds of meters wide.

The best theory that explains the absence of any preserved crater around it is that, this piece of rock must have hit the earth’s surface at a very low angle. As a result, it must have skipped on the surface like a flat stone on water surface. And in the end, must have landed at the place where it lies today.

Elephant Bird – The Heaviest Bird Ever

By Anupum Pant

Scientific Name: Aepyornis maximus

No, it isn’t about a bird with a trunk or tusks. Weighing almost half a ton, the aptly named, elephant bird of Madagascar, was the heaviest bird to have ever existed on earth.  It looked like an Ostrich on steroids and of course it was a flightless bird. The number 3 bird in this picture is an illustration of the Elephant bird (around 10 feet in height) [image]

Note: Although we say that it was the heaviest bird to have ever existed, we can only say that because we haven’t been able to find any traces of a larger bird yet.

Interestingly, it wasn’t something that belonged to the Dinosaur era. It went extinct recently, around the 17th or 18th century, probably due to humans hunting it for food. Since cameras did not exist at that time, only written accounts of its sighting have been found.

As logic dictates, a huge bird would lay huge eggs. So, with a volume of about 180 to 250 times that of a chicken egg, measuring about 1 feet in height, its eggs were the largest laid eggs ever; larger than human heads. The shells could hold around 11 liters of liquid. Its eggs were said to have fed whole families. Some of them have been preserved – Some are being auctioned and some are available in museums. National Geographic Society in Washington holds a specimen that has the skeleton of an unborn Elephant bird.

 

Gomboc – An Object That Never Falls

By Anupum Pant

Visit blogadda.com to discover Indian blogs
There’d be hardly anyone among us who hasn’t played with a roly-poly toy during their childhoods. If you know it by some other name, you could think of it as a toy that never falls, no matter how hard you hit it, and sells in variants which look like this. That isn’t exactly what a Gomboc is, but you get an idea about what it does – It does not fall. For more, read on.

What is a Gomboc?

A Gomboc (Gömböc) is a mathematical 3-D shape which has only one position in which it can stand and is made up of a single material  of uniform density. If you try to make it stand in some other way, or try to knock it down, it moves back to that single stable position, gradually. When placed on its side, it starts rocking magically, gains momentum, straightens itself and gradually comes to rest in that single position. Here is a video of a Gomboc doing its thing.

A Gomboc is an object surrounded by a number of complex curves, it takes an immense amount of accuracy to get the surfaces right. An accuracy of  the orders of around 1/10th of a human hair’s thickness is required for it to work properly. For better, people have started 3D printing these complex shapes.

The world’s largest Gomboc was displayed in China in the year 2010 which measured around 3 meters in all directions.

Terrestrial tortoises, who use a similarly shaped shell to get on their feet when turned upside down, were using it long before humans had found a way to construct it. The first time we made it, was in the year 2006. Evolution got there first!

How is it different than a Roly-Poly toy?
A roly-poly toy usually has an internal counter weight made up of a heavier material. But a Gomboc is made up of a single material.

Uses: Use it as a paper weight or to gift it to your friend who is a math geek. Tortoises use it to save their own lives.

Where can I buy one?
You can get one for yourself from an official website of the inventors – Here.
