... If you could point a telescope anywhere in the sky, where would you look? The Personal Space web application allows you to make a direct and personal connection to the universe by linking significant events in your own life with what was above you in the sky at that moment. ... Personal Space is an online invitation to connect with and explore the universe in an intuitive way by presenting beautiful astronomical images of the sky overhead at key moments and places of personal significance. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...
