Space Oddities – Part II

Self-administered pat on the back to me.

A few days back, in the month of December I had compiled a list of 6 space oddities that really interested me. At that time, I was pretty sure I would stumble upon a few more odd/interesting things about space within a month or two. With that in mind, I had decided to suffix the heading with “Part – I”. Four months have passed. That was a very thoughtful thing I did – thinking 4 months into the future. I have to appreciate my forethought (with a self-administered pat on the back) for doing that because today I’m back with a few more of these odd / interesting things about space and I’m still not embarrassed about the heading for the post.

So, here is the part II of space oddities (read the part I here):

1. A Hole in the Universe

About 7 years from now, researchers from University of Minnesota found out about a really huge void in our universe. The abnormal hole measures approximately sixty billion trillion miles. In easier words, it is about 10 Billion light years wide. Imagine! A beam of light would takes 10 Billion years to travel through that empty place. How lonely would it be at the centre of it. The void is bigger than anything else scientists have ever seen in space.

The whole volume of space shows no sign of any stars, planets, asteroids, gases, clouds, dust. The volume doesn’t even have any signs of dark matter (95% of our universe is dark matter) too. [read more about it]

2. Costliest thing ever built

Think of a huge 5 bed room house floating in space that can be seen moving from the surface of the earth with the naked eye! Yes, I’m talking about the International Space Station. It is a whooping 200,000 kg object that is 171 feet long, 240 feet wide and 90 feet high.

When it comes to the price of building something this huge in space, it beats everything from the most lavish sky scrappers to the most largest dams  ever built. The price of building it is estimated to be about $160 Billion and fortunately the cost is shared by Canada, the European Union, Japan, Russia and the US. It is officially the most expensive object ever constructed, and it is NOT on earth! – Guinness book of World Records.

Space Oddities – Part I

By Anupum Pant

Note

During the past few days, I came across a couple of interesting things related to space, which I felt were worth sharing. Individually, none of them could have been made into a good long article. So, I thought of compiling a list of these amusing post-lets to form a single good read.

Also, in the words of Chris Hadfield: Since Space is profound, endless, a textured black, a bottomless eternal bucket of untouchable velvet and untwinkling stars, it is a place that holds infinite possibilities for me to collect more of such amusing ideas. Therefore, I have suffixed the title of this post with a phrase – Part 1 – that leaves an open possibility for other such articles. If you’d like to contribute snippets for the upcoming parts of this post, you can get in touch with me. [About Page]

Space oddities begin

1. A year in Venus:

Two facts. Venus rotates on its axis only once every 243 earth days. It orbits the sun every 224.64 earth days. But, both of these things put together mean that on Venus, a day is longer than a year. Or simply put, almost everyday is everyone’s birthday. Wonderful, isn’t it?
Also, Venus rotates backwards. So, the sun as seen from Venus, rises from the west and sets in the east. The rotation is so slow that it is unable to generate a magnetic field like earth.

2. International Space Station:

Floating around in the ISS, it is often possible for an astronaut to get struck floating in the middle of a room when walls are out of reach. To get out of such a position, astronauts have to be patient and have use the drafts of light crosswinds from fans or call for help for a physical push. – [Source]

3. Going from ‘a planet’ to ‘not a planet’:

Discovered in 1930, Pluto was originally classified as the ninth planet from the Sun. In the year 2006, this definition excluded Pluto and reclassified it as a member of the new “dwarf planet” category.
For the whole time during which Pluto was a planet, it did not complete even half a orbit. That means within half a Pluto year, it went from being called a planet to not a planet. Sad.
Today, Pluto is the tenth-most-massive body observed directly orbiting the Sun or the largest object in the Kuiper belt.

4. Visibility from space:

We have always been told that the only man-made object that can be seen from space is the Great Wall of China, but it is NOT true. You cannot actually see the great wall of China from space.
What you can actually see is the biggest structure made by living organisms (not humans) – The Great Barrier Reef.

5. Sun as seen from Mercury:

On Mercury, the sun appears to briefly reverse its usual east to west motion once every Mercurian year. The effect is visible from any place on Mercury, but there are certain places on its surface, where an observer would be able to see the Sun rise about halfway, reverse and set, and then rise again, all within the same day. [Sun’s unusual behaviour as seen from Mercury]

6. Flying on Titan is easy:

The largest moon of Saturn is a very peculiar place. It is the only known moon to have an atmosphere. But that isn’t all.
Its atmosphere has 1.19 times more mass than the earth’s atmosphere. Secondly, the gravity is far lower as compared to earth. This means, had there been humans on Titan, they would have been able fly in Titan by just flapping wings attached to their arms.

In the end, I’d like to leave you with two very interesting things. An inspirational comic by Zen Pencils and a revised version of David Bowie’s Space Oddity, recorded by Commander Chris Hadfield on board the International Space Station (I had this on repeat the entire time I was writing this article):
