LIGHTSPEED, COSMIC SPEEDLIMITS, AND (FINALLY!) LOOKING INTO THE PAST (Part 2)

Posted on February 15, 2016 by harperastronomyblog

In one of my previous posts , I explained what a light-year was and how the speed of light remains constant in a vacuum (a.k.a. space). I also explained that there would be another post explaining some of the things that I couldn’t fit in that post. Now I am finally ready to finish–the long awaited!–part […] Continue reading →

Hearing the Universe

Posted on February 15, 2016 by alecsolarsystem

One of the most groundbreaking theories in astronomy has just been proven with the announcement last week that gravitational waves have been detected. Einstein had predicted these waves in 1916 in his theory of general relativity, and they were only just found today using lasers, which Einstein also laid the foundation for one year later in 1917. These […] Continue reading →

Tidal Forces

Posted on February 15, 2016 by lindseynestor

As a person that has always been happiest by the ocean, I really enjoyed learning about tides and decided to do some further research into other effects and instances of tidal forces in our solar system. Just as the Moon causes tides on the Earth, Earth creates tidal forces acting on the Moon. This is […] Continue reading →

Planet IX

Posted on February 15, 2016 by lawlorsolarsystem

I have been fascinated by the possibility of a new ninth planet ever since I heard about it, so I thought I would use this blog to share some information on it. First, the discovery of it came, in many ways, from Pluto itself. Once astronomers discovered that there were other objects like Pluto (Kuiper […] Continue reading →

It’s Gettin’ Hot in Herre

Pharrell was probably thinking of bodies when he helped penned this hit for Nelly. Despite what the title may suggest I don’t think he had thermal radiation in mind… Continue reading →

Stonehenge

Posted on February 15, 2016 by lawlorsolarsystem

The layout of Stonehenge has confounded historians and archaeologists for years, and they still do not entirely know why it is there. But historians have theorized that at least part of the layout has to do with astronomy. One of the stones, called the Heel Stone, is lined up exactly with the Sun on the […] Continue reading →

Celestial NASCAR: Kepler’s Laws of Planetary Motion

Posted on February 15, 2016 by d51blog

Before 1609, the scientific consensus in Europe was that the planets orbited the Earth in perfect circles; even dissenting views such as Copernican heliocentricism relied upon perfect circles to guide objects around the Sun. Johannes Kepler, however, motivated by minute errors in planetary distances discovered when attempting to construct Copernicus’ model, revolutionized astronomy with his laws of […] Continue reading →

The Gravity Slingshot

Posted on February 15, 2016 by martisnv

Recently we discussed a maneuver called the gravity assist. NASA uses this technique frequently, most notably with the Voyager probe during flybys of Jupiter and Saturn. In simplest terms, a gravity assist changes a spacecraft’s velocity by going through a … Continue reading → Continue reading →

Blog #3 James Webb Space Telescope

Posted on February 14, 2016 by seanmcsolsys

The flagship of the next generation telescopes launches in October 2018. The James Webb Space Telescope is an infrared telescope with its focus on the very first light from the Big Bang. With its 6.5 meter primary mirror and various cameras and spectrometers, the JWST will study the boundaries of the observable universe as well […] Continue reading →

The Hubble Space Telescope

Posted on February 14, 2016 by martisnv

Until this past September when LIGO heard gravitational waves, our knowledge of the universe has come from visual observations. When Galileo began using his telescope in the early 1600s, our notion of the natural world completely evolved. Today, we have telescopes whose … Continue reading → Continue reading →
