Asteroid 2001 FO32 ( see image) makes its closest approach to Earth, giving astronomers the chance to study the rock as it passes.

The largest asteroid to pass by Earth this year has made its closest approach, posing no threat of a cataclysmic collision but giving astronomers a rare chance to study a rock formed during the beginning of our solar system.

The asteroid was two million kilometres (1.25 million miles) away at its nearest, according to NASA – more than five times the distance between the Earth and the Moon but still close enough to be classified as a “potentially hazardous asteroid”.

2021-03-21 13:24:33 What is Permafrost?

Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight. These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.

Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath. Although the ground is frozen, permafrost regions are not always covered in snow.

What Is Permafrost Made Of?
Permafrost is made of a combination of soil, rocks and sand that are held together by ice. The soil and ice in permafrost stay frozen all year long.

Permafrost soils also contain large quantities of organic carbon—a material leftover from dead plants that couldn’t decompose, or rot away, due to the cold and minerals.

2021-03-18 14:10:33 Where did all of Mars' water go?

News: Missing water on Mars may not have 'escaped to space', could be lurking underground: Study

Billions of years ago, Mars was home to lakes and oceans — but where all the water went to transform the planet into the desolate rock we know today has been something of a mystery. Most of it was thought to have been lost to space, but a new study funded by NASA proposes that it didn't go anywhere but is trapped within minerals in the crust. "We're saying that the crust forms what we call hydrated minerals, so minerals that actually have water in their crystal structure.

2021-03-16 20:13:55 What is Sandstorm or Dust Storm?

News: Beijing witnesses worst sandstorm in a decade, causing severe air pollution

A dust storm, also called sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another.

Drylands around North Africa and the Arabian peninsula are the main terrestrial sources of airborne dust.

The term sandstorm is used most often in the context of desert dust storms, especially in the Sahara Desert, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface.

Question: What is a Dust Bowl?
