Point Nemo – The Spacecraft Graveyard

In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place that humans live – in fact, there is no land there – not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called “Oceanic pole of inaccessibility”.Notes 1

Scary Question: What Will Happen if Natural Resources Run Out?

On our wonderful planet, there are multiple natural resources that help make life easier. We use trees for making paper products and they provide us with oxygen. We use natural gas to heat our homes and coal to help us produce electricity. Freshwater fish are a staple in the American diet and we pump billions of barrels of oil out of the ground to fuel our automobiles.

But what happens when natural resources become scarce, or worse, when they run out?

What are the implications of such a thing? And how can we create environmental sustainability?

Here’s what you need to know.

Structure of the Earth

The universe is shrouded in mystery, and part of this mystery involves our own little planet. Although there has been countless research, the scientists and experts have only been able to barely scratch the surface (both figuratively and literally) in case of planet earth.

However, the studies in Seismology have allowed us to gather sufficient information about the Earth and its structure. The planet comprises several layers, which have their own attributes, and composition. So let’s dive in further to discover some enlightening aspects.

What causes the phases of the moon?

Despite we always see the same side of the Moon, it still looks a little different every night. Sometimes we see only a thin crescent, sometimes a half-moon, sometimes a full moon, and other times in-between. Sometimes even the Moon seems to disappear entirely. These “shapes” called lunar phases or phases of the Moon. A lunar phase is the shape of the directly sunlit portion of the Moon as viewed from Earth.

What Time Are We Living In? Geologists Fight It Out!

Attention: Earth Science or Geology enthusiasts, scientists have recently uncovered findings that point to a new age in the timeline of the planet. The discovery of a stalagmite from a cave in Meghalaya, India led the International Union of Geological Sciences (IUGS) declare that we have indeed reached the Meghalayan Age in the Holocene Epoch. The newly-discovered stalagmite is hailed as the official time stamp of the beginning of the Meghalayan Age, and it dates back about 4250 years.

Video: NASA Balloon Mission Captures Rare Electric Blue Clouds

An amazing video: a recent NASA long-duration balloon mission observed a thin group of seasonal electric blue clouds which are known as noctilucent clouds or polar mesospheric clouds (PMCs). Forming 50 miles (80 km) above polar regions in summer they are Earth’s uppermost clouds and only visible around twilight. PMCs are composed of ice crystals that glow bright blue or white when reflecting sunlight.

NASA Has Published Statistics About the World’s Sandy Beaches

NASA has published some interesting statistics about the world’s sandy beaches on Earth Observatory webpage. According to the images taken by Landsat satellitesNotes 1 (Landsat 5 and Landsat 8Notes 2, 3), about 31 percent of the world’s coastlines are sandy. Africa has the highest proportion of sandy beaches (66 percent) and Europe has the lowest (22 percent).
