Gravitational Lens by astronomical objects.

Posted on February 10, 2018 by kkim7243

A gravitational lens is an observed image of light that is bent into a circle around the gravitational objects. The general relativity theory or the curvature of the space time is used to explain this amazing phenomena. When there is a sufficiently large gravitational objects such as stars, black holes and celestial bodies in the … Continue reading Gravitational Lens by astronomical objects. → Continue reading →

All the Light We Cannot See

Posted on February 9, 2018 by therestisstardust

Could I really claim to be interested in astronomy whatsoever if I didn’t express my overwhelming fascination with dark matter? Seriously though, I get the feeling that most people without a solid background in astronomy don’t grasp how much of a real phenomenon dark matter is. The name itself sounds like something made up from […] Continue reading →

Gravity Waves

Posted on February 14, 2017 by pkunetz97

Have you ever wondered what the speed of gravity is? Were you under the assumption that the force of gravity was immediate? Like everything else in the universe, gravity has a finite speed. In fact, gravity travels at precisely c, the speed of light in a vacuum. This was first theorized as a result of Einstein’s […] Continue reading →

Blog #2: HAT-P-2’s Heart

Posted on February 14, 2017 by lillyastro2110

A very appropriate post for Valentine’s Day. NASA’s Spitzer Space Telescope has discovered a unique quality of a star and its orbiting planet that are some 370 light years away. The gravitational interaction between the two cause some vibrations in HAT-P-2 when its orbiting planet HAT-P-2b gets close. HAT-P-2b is a planet with a mass … Continue reading Blog #2: HAT-P-2’s Heart Continue reading →

Gravity in Space?

Posted on February 13, 2017 by Matt Machado

Videos of astronauts floating around inside space shuttles have led many to believe that gravity does not exist in space. However, this is simply not true. While the force of gravity affects, for example, astronauts who are orbiting the Earth in the International Space Station differently than it affects us, it still exists in space, […] Continue reading →

Phobos is Doomed and Should be Afraid

Posted on February 13, 2017 by Ashley Garcia

The red planet is orbited by two moons, Phobos and Deimos (Greek for Fear and Panic respectively), and given the predicted fate of Phobos, the small moon has good reason to be afraid. Both moons may have originally been asteroids that were captured by Mars’ orbit, however in time, Phobos may become a ring around… Continue reading Phobos is Doomed and Should be Afraid Continue reading →

Gravity vs. Light

Posted on February 12, 2017 by ksun1

The light from a distant galaxy gets warped and distorted thanks to the immense gravity of the closer reddish-orange galaxy We usually think light is pretty fast. Usain Bolt can set new records for how quickly man can run. There are motorcycles that can travel faster than our own nerve impulses. Aircraft has long since broken the sound barrier. […] Continue reading →

Death by Black Hole

Posted on February 12, 2017 by josiezd

Unfortunately, astronomers and physicists are pretty sure you can’t just go through a black hole and pop out the other side – you will, in fact, die. The real question is, how exactly will you die? Continue reading →

The Earth’s Gravity

Posted on February 12, 2017 by jakesindelar

  Gravity on Earth acts on all objects with the same force. No matter their mass, objects fall and accelerate at a constant rate. Due to the air resistance of different shapes, this is not always apparent. On a planet or moon lacking oxygen, the law could be simpler to demonstrate. On Earth, falling objects…Read more The Earth’s Gravity Continue reading →

Zero Gravity

Posted on February 7, 2017 by brynnabhall

For most children, at some point in time, the only logical career path in the entire world is astronaut. They usually say it with reverence, for the word is akin to something half way in between magician and alien, full of all the magic and surprises that only someone who hurdles through the final frontier … More Zero Gravity Continue reading →
