Myers-Briggs Personality Chart
The Myers-Briggs Type Indicator (MBTI) assessment is a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions.

Exploring the Moon
People have dreamed of exploring the Moon for hundreds of years. The United States and Russia made the dream a reality in the middle of the 20th century. In 1959, Luna 1- the first spacecraft to leave the Earth’s gravity – was launched toward the Moon. A decade of intense space activity followed as Russian and American probes, robots, and crewed craft were sent to investigate and land on the l...
Jupiter's Moons Explained
The planet Jupiter has 67 affirmed moons. This gives it the most substantial entourage of moons with "sensibly secure" circles of any planet in the Sun oriented System.

From the close of the 19th century, handfu...
Driving Force That Drives Galaxies Apart
The universe is expanding at an ever – increasing rate, with something that astronomers call dark energy appearing to push it apart faster than gravity can pull it together. Type la supernovas are stars that explodes with a predictable brightness. Light from distant supernovas locks dimmer and redder than expected, implying that the universe is expanding. The more distant the star, the fast...
Variable Stars and What They are
These maps show stars visible all year in the northern and southern hemispheres. They also mark the position of interesting objects, such as star clusters and galaxies. To see what is visible, face north in the northern hemisphere and south in the southern hemisphere. The Variable stars contains pulsating variables, the eclipsing variables and the rotating variables. Toward the end of their...

The color of planets depends on the spectrum of the star’s light, which astronomers can easily observe, and filtering of light by air and water, which the author and her colleagues have simulated based on the likely atmospheric composition and it’s own effects.
Other Solar Systems
Is our Solar system unique in the Universe ? Until recently, astronomers could only guess whether other stars are orbited by planetary systems. Extrasolar planets – those that orbit stars other than the Sun – are difficult to detect, because they are about one – billionth the brightness of their parent stars. Extrasolar planets can also be detected by watching for a drop in brightness as ...
