demonstrations.wolfram.com The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. The precession in the orbit of the planet Mercury (about 43 seconds of arc per century) was correctly explained by Einstein’s theory of gravity. This Demonstration exaggerates the effect by making the mass of the Sun around 10^6 times greater; also, you… Contributed by: Enrique Zeleny

Ted Simons interviews a shining star in the universe of astrophysics, Neil degrasse Tyson. The author and host of PBS NOVA sciencenow talks about what sparked his interest in the cosmos. Ted also asks what Tyson has against Pluto, the celestial body that was discovered at Flagstaff’s Lowell Observatory. Ripped this video from AZPBS to make it more public. The video was by no means easy to access so it would only be appropriate to make it more accessible.

Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun. If a star that massive or larger undergoes a supernova explosion, it may leave behind a fairly massive burned out stellar remnant. With no outward forces to oppose gravitational forces, the remnant will collapse in on itself. The star eventually collapses to the point of zero volume and infinite density, creating what is known as a ” singularity “. As the density increases, the path of light rays emitted from the star are bent and eventually wrapped irrevocably around the star. Any emitted photons are trapped into an orbit by the intense gravitational field; they will never leave it. Because no light escapes after the star reaches this infinite density, it is called a black hole.

, some of us came together in the interest of spreading the science of LIGO to many more people. A lot of work (on top of research!) went into the production of this video, so we hope you enjoy it and learn a little about LIGO science. To learn more about LIGO, visit www.ligo.org. To help with LIGO at home, go to www.einsteinathome.org.

writing popular science books and for co-writing and presenting the award-winning 1980 television series “Cosmos: A Personal Voyage”, which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel “Contact”, the basis for the 1997 Robert Zemecki’s film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 …
