Gravitational Lensing

“Light always travels in a straight line.” But does it, always? What if I tell you that the light can bend? Seems non-intuitive, but come find out how light can bend around massive objects, how gravity, plays a role in this; and what exactly is Gravitational Lensing, in Saieesh’s article on The Wandering Star, a blog by SEDS Celestia. Read more to learn how gravity bends light like a telescope.

Roche Limit

Ever wondered what would happen if the Moon gets too closed to the Earth? It may seem on first thought that it’ll simply collide. But what if I tell you that it will be torn apart before reaching the surface of the earth. Surprised? Find out what really happens and learn more about the interesting concept of Roche Limits. Read about it on SEDS Celestia’s blog The Wandering Star.
