What is a pulsar?

Posted on February 14, 2018 by justinrstevens

              WHAT IS A PULSAR? Pulsars are some of the most interesting astronomical objects out there and are the subject of intense study by teams of scientists around the world. Pulsars are rapidly rotating neutron stars that emit beams of intense energy from their magnetic poles.  Here, it is…

1 Shift, 2 Shift, Redshift, Blueshift

Posted on February 14, 2018 by jonahastroblog

Space is vast. In fact, vast enough to contains many million, billions, and trillions of galaxies and other celestial objects. So the ultimate question is, how do scientists keep track of all of the celestial bodies? How do we know that the Andromeda galaxy is coming toward us if we can’t tell if it is… Continue Reading → Continue reading →

Gravitational Waves and Extra Dimensions

Posted on February 13, 2018 by stellarastronomy1995

The existence of dimensions beyond the three spatial and one temporal we experientially inhabit in our current model of spacetime has been a longstanding discussion touched on by various physicists and the scientific community. It has been suggested that gravity would propagate throughout these other dimensions, a thought brought about in attempts to somewhat unify … Continue reading Gravitational Waves and Extra Dimensions → Continue reading →

Just Because You’re Bulkier, Doesn’t Mean You Pull More

Posted on February 13, 2018 by jonahastroblog

We’ve all seen and learned about the cosmos and the stars up above. We learned that the Earth revolves around the Sun because the Sun’s force on the Earth is greater than any of the other major celestial bodies near this. However, something that many people forget is that this process is facilitated by Newton’s Universal… Continue Reading → Continue reading →

Retrograde Motion: Illusions and Jinxes

Posted on February 12, 2018 by aquarianastronomy

Understanding the heavens has proven confusing for countless generations of humans in part because of the illusions caused by our perspective from earth. For millennia, the majority opinion was a geocentric universe, where the sun, moon, planets, and stars revolved around the earth, since they all seemed to do so from the earth’s perspective. All […] Continue reading →

Derivation of Kepler’s Second Law

Posted on February 12, 2018 by danielsolarsystem

Here is a detailed derivation of Kepler’s second law of planetary motion. I find this derivation of Kepler’s Second Law and similar derivations I have seen for other laws extremely interesting. This is actually the most straightforward of the derivations of Kepler’s three laws. The reason I am so intrigued by this derivation is because … Continue reading Derivation of Kepler’s Second Law → Continue reading →

Moon and Tides – The Magic of Gravity

Posted on February 12, 2018 by dempsy

Our sea has a periodic rising and falling phenomena. At a time, the sea will go up and reach to the peak, and at another time, the sea will go down and leaves us an island or a beach. This phenomena is called tides. The tides are mainly caused by gravitational force from Moon. When … Continue reading Moon and Tides – The Magic of Gravity → Continue reading →

Absolute Hot

Posted on February 12, 2018 by yadavdhruv

We all have heard about absolute zero – the coldest temperature possible. At this point, atoms cease to move completely. All heat is really is just the movement of atoms and the energy with which they’re moving. Hotter things tend to have more energy, and their atoms move more. Thermodynamically, it is impossible to reach … Continue reading Absolute Hot → Continue reading →

gravity.wav

Posted on February 12, 2018 by Nathan Xiao

  Picture: Artist depiction of gravitational waves at work Gravity has long been one of the most transfixing ideas in our universe. For centuries, we have tried to crack the code of what exactly lies beneath our 9.8 meters per second squared. Since the apple first dropped on Newton’s head, we’ve been pining to understand … Continue reading gravity.wav → Continue reading →

Physics in the Olympics

Posted on February 12, 2018 by astronomydylan

We have all heard the joke which rings all too true: the Olympics need one average person competing for reference. Last night, olympic figure skaters dazzled the international community with their many spins and jumps. I found myself extremely curious as to how the skaters are able to spin so many times with apparent ease. … Continue reading Physics in the Olympics → Continue reading →
