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.


SEDS Celestia brings to you an article written by Suchetan R S about the advancing new space tech to reach orbit with much less energy : Space Tethers. Learn all about this future technology and the physics behind it by reading this article.


Greeting from SEDS Celestia!
Lets dive into the interesting mind boggling scientific phenomena which not only tricks your mind but makes you also adore the beauty of this universe.

Understanding Telescopes and Binoculars-Part 3

Greeting from SEDS Celestia. Its time to get into a bit old math and how it helps us during star gazing and observations. We present to you this article which deals with Co-ordinate system used to co-ordinate (xD) Sky-watching and finding stars relatively easily. We discuss two major systems in a quirky and fun to make observations easier.
