If one were to capture and bottle a comet's 10,000 mile vapor trail, the amount of vapor actually present in the bottle would take up less than 1 cubic inch of space. Members of the Dogon tribe in Mali, Africa, for many centuries worshiped a star known today by astronomers as Sirius B. The Dogon people knew its precise elliptical orbit, knew how long it took to revolve around its parent star, Sirius, and were aware that it was made up of materials not found on Earth—all this centuries before modern astronomers had even discovered that Sirius B existed. Deimos, one of the moons of mars, rises and sets twice a day. To an observer standing on Pluto, the sun would appear no brighter than Venus appears in our evening sky. Saturn's rings are 500,000 miles in circumference but only about a foot thick. Five times as many meteors can be seen after midnight as can be seen before. The star Antares is 60,000 times larger than our sun.
Boletim em Órbita nº 91 (Edição Especial) A conquista da Lua foi uma das maiores aventuras da Humanidade que continua a marcar gerações. A aventura dos doze astronautas que pisaram o solo lunar marcou o culminar de um esforço e de uma corrida entre duas super-potências que ‘lutavam’ no espaço pela hegemonia numa guerra que se dizia fria. Porém, mesmo 40 anos após as primeiras explorações lunares, ainda existem pessoas que duvidam de que alguma vez o Homem tenha caminhado sobre o nosso satélite natural.

My Solar System - Motion, Acceleration, Velocity Topics Motion Acceleration Velocity Position Gravity Description Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other. Sample Learning Goals Predict the necessary mass, velocity, and distance from the sun of a planet in order for this planet to make a circular orbit around a sun.What happens when you increase or decrease the mass of the planet, but keep everything else constant?

LHC_Homepage The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre.
