Tidal Streams in Massive X-ray Binary Systems: Neutron Star Close-up
A tiny neutron star orbits incessantly around a massive star with a diameter a million times larger than its own. The high luminosity of the massive star drives a strong wind from its surface. The neutron star crashes through this wind at over 300 kilometers per second. The gravity and X-ray luminosity of the neutron star act to disrupt the wind, producing an extended wake of dense gas trailing behind the neutron star. In this simulation, the tidal distortion of the primary star and the resultan

Great Zoom out of Houston, Texas: Reliant Stadium (with spin)
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl

SAMPEX - A Synoptic View of Earths Electron Radiation Belts: North Pole Energetic Fluxes from HILT
The Solar Anomalous and Magnetospheric Particle Explorer, SAMPEX, measures fluxes of energetic particles from the sun, the Earths magnetosphere, and cosmic ray sources over a broad range of energies. The four instruments aboard SAMPEX are the Low-Energy Ion Analyzer (LEICA), The Heavy Ion Large Telescope (HILT), The Mass Spectrometer Telescope (MAST), and the Proton-Electron Telescope (PET).

Simulations of the Breakup of Comet Shoemaker-Levy 9 Employing a Swarm Model: Initial Conditions
The breakup of comet Shoemaker-Levy 9 due to its gravitational interaction with Jupiter in July, 1994 is simulated using a swarm model. In this simulation, the comet is modeled as an initially spherical distribution of 16,384 particles. The particles interact with the tidal field of Jupiter and with each other through inter-particle gravitation and collisions. All simulations were performed on the Maspar MP-2 at NASA-GSFC.

4.5 Some general results

We next establish some general results about Euler characteristics. We start with a theorem that tells us what happens to the Euler characteristic of a surface when we remove an open disc.

Job interviews
Job Interviews is one of several Futures workbooks which help students choose and prepare for their careers. Like the other workbooks in the series you can dip in and out doing the exercises which are most relevant to you. You might want to include the exercises or the output in your personal development plan or e-portfolio. Interviews are still the most commonly used method for assessing a person’s suitability for a job. In the UK 99 per cent of employers use selection interviews to recruit

Galileo: Sun-Centered System
Before the 17th century, people generally believed that Earth was at the center of the universe. Galileo, however, was not afraid to challenge existing beliefs when he published his work in support of the Sun-centered, or heliocentric, Copernican theory. In this video segment adapted from NOVA, learn about the two opposing worldviews and the strong piece of evidence Galileo offered to support the heliocentric theory. Closed captioning included. Run time 05:06.
