Mercury & Venus the Two most Hostile Planets in the Solar System

A look at the two most hostile planets in the solar system -- Mercury and Venus; one gouged with craters, the other a greenhouse cauldron of toxic gases and acid rain; both scorched by their close proximity to the sun. Scientists theorize about what sort of life could evolve on these alien worlds.Mercury is the smallest and closest to the Sun of the eight planets in the Solar System,[a] with an orbital period of about 88 Earth days. Seen from the Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet. This rapid motion may have led to it being named after the Roman deity Mercury, the...

What is Space?

Space. It separates you from me, one galaxy from the next, and atoms from one another. It is everywhere in the universe. But to most of us, space is nothing, an empty void. Well, it turns out space is not what it seems. From the passenger seat of a New York cab driving near the speed of light, to a pool hall where billiard tables do fantastical things, Brian Greene reveals space as a dynamic fabric that can stretch, twist, warp, and ripple under the influence of gravity.

Is There an Edge to the Universe?

It is commonly theorized that the universe began with the Big Bang 13.7 billion years ago. But since we can only see as far as light has traveled in that time, we can't actually make out the edge of the universe. Could it be that the universe is infinite?

Cosmic Journeys : Earth in 1000 Years

This edition of COSMIC JOURNEYS explores the still unfolding story of Earth's past and the light it sheds on the science of climate change today. While that story can tell us about the mechanisms that can shape our climate. it's still the unique conditions of our time that will determine sea levels, ice coverage, and temperatures. Ice, in its varied forms, covers as much as 16% of Earth's surface, including 33% of land areas at the height of the northern winter. Glaciers, sea ice, permafrost, ice sheets and snow play an important role in Earth's climate. They reflect energy back to space, shape ocean currents, and spawn weather patterns....
