Deep-Space-1 was a space probe launched by NASA on 24 October 1998. The spacecraft, lifted into space that day by a Delta rocket, carried twelve new technologies, which were designed for deep-space usage. The mission objectives were to try out all the technologies that might...

The sun is the nearest star to Earth, and the source of the energy that powers life on Earth. It is made mostly of hydrogen and helium, the predominant building blocks of the universe, glowing with inconceivable heat. The sun may be 5,600 degrees...
The tenth planet
By: Jason Sorrell
Those of us who have an interest in astronomy and astrology are aware of an accurate, though complex formula which predicts the presence and positions of planets in our solar system. It is based on the observed movements of bodies in space which we are...
Would aliens look like us?
By: Darren Chau
There is only one Earth, one Homo sapiens, in all the cosmos after all, it is hard to believe that billions of evolutionary steps could be perfectly reproduced elsewhere. In that sense, our species is unique. But where does one draw the line between similarity...
Why Pluto is not a planet anymore
By: Laurel Kornfeld
Pluto IS a planet because unlike most objects in the Kuiper Belt, it has attained hydrostatic equilibrium, meaning it has enough self-gravity to have pulled itself into a round shape. When an object is large enough for this to happen, it becomes differentiated with core...
Noteworthy features of the solar system

The Great Red Spot is a gigantic high-pressure system that is likely to have raged on Jupiter continuously for the past 340 years, ever since it was first observed by man. During this period it has fluctuated in both size and colour; its famous reddish...
The Big Bang Theory
By: R K vanderHoek
The "Big Bang Theory" describes a rapid initial and then slowed, but, now accelerating, continual cosmic expansion of our observable universe from a super, hyper, mega, giga, uber, very, very, very dense particle of energy-mass, about 13.7 billion years ago. This has been confirmed...
Methane on Mars
By: Argann Argannon
The easiest explanation for methane is geology. However, when you look at the amount they found (minute at best), then biology is a better preliminary guess. Which is all it is on both sides of this argument at this point, a guess. Almost forty years...
Space exploration in the future
By: Irrira Rikki
Already well into a decade of the 21st. Century, we have sent our Kepler Space Ship - unmanned - with the hope of finding habitable planets. But Space exploration in our future must be a whole new technological shift as well as our level of...
Noteworthy features of the solar system
By: Carolyn Collins Petersen
Welcome to Olympus Mons! Some day people are going to land on the planet Mars and begin the "up close and personal" exploration of its dry, dusty, frozen surface. They'll have the benefit of years of Earth-based Mars exploration to help them to decide what...
