The Origin of Tides: The Sun & The Moon

Posted on February 9, 2020 by maverickbennett

How much impact do The Sun and The Moon have on Earth’s tides? Also, what would happen to the Earth’s tides if there were no moon? These are questions that are covered in this blog post about tides. The Earth’s tides are results of the gravitational pull from the Sun and the Moon on Earth’sContinue reading “The Origin of Tides: The Sun & The Moon” Continue reading →

Invisible Stars Bending Space-Time with Gravity

Posted on February 9, 2020 by alexsolarsystem

Researchers at the Astronomical Observatory of the University of Warsaw have recently discovered two previously invisible stars deep within the Milky Way. These binary stars (two stars that effectively orbit each other) were found thanks to a star called Gaia16aye that is considerably farther away. A few years ago, astronomers noticed that Gaia16aye would occasionallyContinue reading “Invisible Stars Bending Space-Time with Gravity” Continue reading →

How Gravity Affects Light

Posted on February 9, 2020 by Reece Boggs

Gravity exerts a force on photons, even though it has no mass. This can distort the things we see if the light that reaches us is being distorted by gravity, as seen in the picture at the top of this post. The confusing aspect of this is that gravity affects this light even though theContinue reading “How Gravity Affects Light” Continue reading →

What’s in a Black Hole?

Posted on April 27, 2019 by Aaron Molotsky

There are few things in the entire Universe that are as terrifyingly awesome as a black hole. To have a region of space exist that contains gravitational forces so strong that literally nothing can escape it (whether it’s a particle, light, or any electromagnetic radiation for that matter) seems like a concept straight out of … Continue reading What’s in a Black Hole? → Continue reading →

Gravity and Sun Size

Posted on March 12, 2019 by JSpin

Gravity as the Driving Force The Sun has a mass of 2 * 10^30 kg. Gravity exerts a compression force on the Sun proportional to this immense mass. So why doesn’t the sun collapse under the weight of its gravity? The pressure of the center of the Sun is about 340 billion times the air … Continue reading Gravity and Sun Size → Continue reading →

Gravity Waves

Posted on March 11, 2019 by Jonathan Roberts

Venus is the unfortunate victim of a runaway greenhouse effect. Not only does this make the planet uninhabitable, it also causes a tremendous degree of difficulty in observing the planet’s surface. However, there are many interesting things to gain from Venus by just looking at the atmosphere, including a massive gravity wave. Gravity waves in … Continue reading Gravity Waves → Continue reading →

Newton’s Law of Gravitation and General Relativity

Posted on February 10, 2019 by richardficek

Isaac Newton’s law of universal gravitation first appeared in the Philosophiæ Naturalis Principia Mathematica in July 1687. It describes why that apple fell on Newton’s head (as some stories would have it), why we stay rooted to the ground (without drifting off into space), and why the Earth is locked in orbit around the Sun (among … Continue reading Newton’s Law of Gravitation and General Relativity → Continue reading →

Gravity’s Effect On Everything

Posted on February 10, 2019 by calebglotta

Gravity has an affect on nearly everything in the entire universe. From galaxies, to solar systems, to planets and their moons, and even on the planets themselves (like the tides), if there are objects with mass then gravity is present. Newton’s Universal Law of Gravitation explains the effect of gravity between objects. Newton’s Law says … Continue reading Gravity’s Effect On Everything → Continue reading →

The Universal Law of Gravitation

Posted on February 10, 2019 by anna_h

  Newton’s universal law of gravitation is a fundamental aspect of modern science. The law states that every mass is attracted to every other mass through a force known as gravity. The strength of the gravitational force between any two objects is directly proportional to the product of their masses, which means that increasing the … Continue reading The Universal Law of Gravitation Continue reading →

Black Holes Eating Stars, Get Hungrier

Posted on April 18, 2018 by Caroline Henning

The content of this post is based from an article on Space.com titled, “A Hungry Black Hole Devoured a Star, and Its ‘Burp’ Revealed How It Chowed Down”. So, yeah, this is about to be exciting. In the cataclysmic event known as ASASSN-14li, a star passed too close to a black hole. The enormous gravity … Continue reading Black Holes Eating Stars, Get Hungrier → Continue reading →
