How far beyond Earth will we go to safeguard our species?

The human future in the cosmos could be all but limitless, if we don’t destroy ourselves first. The same would be true of intelligent aliens elsewhere in the Universe, assuming they exist: how far they travel depends strongly on how long they survive as a species. That survival variable, which the US astronomer Frank Drake incorporated into his famous equation on the likelihood of technological civilisations beyond Earth, is unknowable at present because we are the only such civilisation yet identified. Let’s be optimistic and assume that humans are persistent, working their way through the manifest problems of mastering their tools – or at least mastering them long enough to plant colonies off-world, so that our destruction in one place doesn’t mean the death of the species.

Top 6 Biggest Stars in the Universe

What is the biggest star in the Universe? In fact, it is really hard to give an exact answer to this question since the universe is big, neighboring and the other galaxies are billions of light years away from us. But, we can give it a try. Here are the top 6 biggest stars in the Universe currently known by radius.

Technology and its Role in Changing the World Around Us

“Technology is a useful servant but a dangerous master.”

Christian Louis Lange, Norwegian Politician

Technology, over the years, has changed its form, functionality, and contribution to this world in a lot of ways. From the very invention of computers to pagers and walkie-talkies to Smartphone; the list of technological advancements and innovation is endless. If we are to talk about the present day scenario, we can pretty well figure out the impact of technological advancements in our daily life activities. Can you recall when was the last time you were out on streets waiting hopelessly for a cab? Chances are that you cannot probably remember the day.

The flipside of the coin – you could probably recall the last time you booked an Uber to pick you up, directly from your place. That’s technology for you, and this is how it is changing the world around us. Here’s the bigger picture depicting a vivid description of the phenomenon which has influenced the world in various ways, and in different sectors. Take a look.

Rainforests of the World (Infographic)

Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth. They cover only 6% of the Earth’s surface but yet they contain more than half of the world’s plant and animal species. According to the current estimates, around 40% to 75% of all biotic species are indigenous Notes 1 to the rainforests.

What’s more, there are probably millions of species of plants, insects, and microorganisms still undiscovered in tropical rainforests. They are responsible for 28% of the world’s oxygen turnover. More than 20% of the world’s oxygen is produced in the Amazon Rainforest only, that’s why it has been described as the “lungs of our planet”.

Unfortunately, rainforests are rapidly disappearing due to deforestation. The loss is huge, and probably hundreds or even thousands of undiscovered species going extinct every single day. We are losing them forever.

Kessler Syndrome: Space junk can end space exploration, and destroy modern way life

On October 4, 1957, the Soviet Union launched Sputnik 1, the first human-made object to orbit Earth. This event marks the beginning of humanity’s space exploration history. After that, humanity went to the moon, astronauts and cosmonauts performed countless spacewalks, and since the arrival of Expedition 1 on November 2, 2000, the International Space Station station has been continuously occupied. To date, this is the longest continuous human presence in space, having surpassed the previous record of 9 years and 357 days held by Mir. But maybe even more important, we launched thousands of artificial satellites into the Earth’s orbit. These artificial satellites shape our modern life: weather forecasts, broadcasting, communication and GPS are just a few examples. But, there’s a side effect: just like here on the Earth, we are slowly filling the most important part just above us, with junk.  And this junk can end space exploration, and destroy our modern way life. This (very possible) scenario known as the Kessler Syndrome, proposed by the American astrophysicist and former NASA scientist Donald J. Kessler in 1978.
