What Can Survive In Space?

Practically all of us have wondered how impossible it is, for any of us to get into space without a space suit or something similar, to save us from harsh radiation.
Going to space without a space suit can result in many problems for a human. One which includes Ebullism, the process whereby bubbles start to form in body fluids as a result of the ambient pressure being reduced. But one thing stays sure, because of this, your whole body starts to swell. You will swell so good you wouldn't look any less puffy, and going near something pointy won't help.
But what can survive in space?  What can scale through this terrifying dark vacuum without breaking much of a sweat?
Let's consider an animal known as the Tardigrade.
Tardigrades are microscopic living animals that were first discovered by the German zoologist Johann August Goeze in the year 1773. Informally, Tardigrades are also known as water bears or space bears.  These animals dwell in aquatic habitats and have been found in many places: ranging from mountaintops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic. When it comes to their structure, they are eight-legged and are segmented micro animals.

Tardigrades can survive harsh and extreme conditions that have been proven fatal to nearly all life forms, including events that can lead to a global mass extinction, like supernovae or massive meteorite bombardment.
These micro animals can go without food or water, for more than 30 years. Tardigrades, so far, have demonstrated a remarkable resistance to extreme temperature and pressure conditions.
In the year 2007, a sample of these animals was placed outside of a space shuttle that orbited the Earth for 10 days before coming back. Surprisingly, more than 70% of them survived the experience, making us understand them better than we ever did.
It's amazing as to how nearly indestructible this animal is, small equally.
Stay tuned.
