Leaving Solar System at the Speed Of Light

Our Solar system is big, and vast, despite it is really small compared to our galaxy, not to mention the complete universe. To put this into a perspective, you can think yourself as a photon emitted by the Sun. It takes about 8 minutes to reach the Earth after a photon has been emitted from the Sun’s surface. And it takes 5 hours to get out to Pluto from the Earth. The edge of the Solar System is far beyond the orbit of Pluto.

But, where’s the edge of the Solar System? Well, It’s complicated. Informally, the term “solar system” is often used to mean the space out to the last planet – Neptune. Some scientists think that the solar system goes out to the Oort Cloud, the source of the comets. The inner edge of the main part of the Oort Cloud could be as close as 1,000 AU (Astronomical Unit, the distance between the Earth and the Sun, which is around 93 million miles or 150 million kilometers) from our sun. The outer edge is estimated to be around 100,000 AU.

Monkeys Accidentally Kill A Robot Baby Monkey And Then Mourn For It – Amazing Video

Do animals understand death? Do they grieve and mourn for their loss? Do they feel empathy for those who suffer? Yes, is the answer to all these questions.

If you “know” animals you already know this too. And there are many scientific studies that conclude animals can understand death and grieve for their losses. Scientists have known for years that big-brained mammals (i.e. gorillas, chimpanzees etc.) may grieve when a family member or close friend, or even a pet dies. But, now, we know that mourning is found more widely in animals than once science has recognized: it extends to horses, cats, dogs, rabbits, birds, and many more.

Great American Total Solar Eclipse 2017

There will be a total solar eclipse on Monday, Aug. 21, 2017, and the United States will be the best country to watch. It will be also the first total solar eclipse to go coast to coast in the U.S. in 99 years. From Oregon to South Carolina, 70-mile Moon-shadow will race across the U.S. and it will completely block out the Sun for a few minutes. It’s still more than seven months away, but hotels already are selling out as people prepare for the rare and amazing event.

On January 5, 2017, NASA has published the map of the event’s path announcing “…thanks to elevation data of the moon from NASA’s Lunar Reconnaissance Orbiter, or LRO, coupled with detailed NASA topography data of Earth, we have the most accurate maps of the path of totality for any eclipse to date.”

Two stars may collide and light up night sky in 2022

Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.

What would happen if humans became extinct?

In the last few thousand years, humans have had a powerful impact on Earth. Within a geological blink of an eye, we exploded out of Africa to colonize virtually every inhabitable space on the planet. We dammed the rivers, we domesticated animals, deforested many areas, changed the chemistry of the atmosphere and the seas… the list goes on. But, what would happen if humans suddenly become extinct in the future?

One may think “humans are so intelligent, so it’s very unlikely that the entire human race will be gone”. But, in fact, there is a strong chance that it will happen, and probably not in the long run!

If Andromeda Galaxy were brighter, this is what we’d see

Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. But if you don’t know where to look, you won’t notice it. But if it were much brighter, its appearance in the sky would be sensational. The moon is a good reference about what we’d see in the image below:

The Size Of Earth Compared to Other Planets and Stars (and the Universe)

When it comes to big numbers, very big numbers, the human brain is weak. In fact, our brains cannot deal with the really large numbers. That’s why when the subject is Earth, planets, Solar System, galaxies, and in general, the Universe, we cannot truly conceptualize the things. A lot of people think we’re “conquering” space (we are far, far away from that – and maybe we never will), or the “aliens” are regularly visiting Earth as if it is just an hour’s drive from there. In fact, these people don’t truly understand what are they talking about, how big is the universe, how far the stars are, and how the Earth is a tiny, tiny spot in a vast space we are still striving to understand.

But we can try to understand and conceptualize. To put things into a perspective, YouTube user morn1415 prepared a video (he updated a previous video with the new findings in the astronomy).

Human Population Through Time (Video)

The Earth is getting more crowded every single day. As of August 2016, the world population was estimated at 7.4 billion. Our planet is already overpopulated, and despite the growth of the population begun slowing, the situation will be worse: the United Nations estimates it will further increase to 11.2 billion in the year 2100.

Here is a video published by the American Museum of Natural History showing the World’s population through time.

“It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’ resources, even as we approach 11 billion?”
