The Speed of Light

Posted on January 26, 2016 by podolakvandysolarsystem

The speed of light is very, very fast, almost incomprehensibly fast. It is unusual to think that whenever we see an object, light is bouncing off that object and hitting our eye. We perceive this to be instantaneous, but it actually takes some infinitesimal amount of time for light to travel from nearby objects to […] Continue reading →

Posted on January 26, 2016 by harperastronomyblog

We all get it. You’re a Capricorn or a Taurus or a Sagittarius or a(n) [any other zodiac constellation]. You’ve read all of your horoscopes, and they fit your personality soooo well. “This is so me,” you might yell to your friends, completely disregarding the fact that they don’t care which vague internet prediction you identify with.

If there was one thing that early humans revered most, it may have been the position of the Sun.  Ancient cultures around the world, before the first cities ever existed, built monuments to measure the Sun’s position (known as archaeoastronomy).  The most famous of which is Stonehenge in England, which has its entrances aligned to […] Continue reading →

Solar Eclipse

Posted on January 25, 2016 by OscarBen

A total solar eclipse. Source: SoftPedia There are two types of eclipses, lunar and solar, but I’d like to talk about the latter. Solar eclipses can be broken down into four subtypes: total, partial, annular and hybrid. In order for any of these to happen, the Sun, Moon and Earth must form a straight–or almost… More Solar Eclipse Continue reading →

Posted on January 23, 2016 by d51blog

  A solar eclipse, which is the only acceptable way to propose to an astronomer, is a fairly uncommon event which occurs when the Moon passes between the Earth and the Sun. Although the Moon is much smaller than the Sun, it is able to completely block the Sun because it is much closer to the […] Continue reading →

What if Earth stopped spinning?

Posted on March 15, 2015 by agiantchicken

*Warning: rather long documentary!* I’ll sum up the documentary, but suggest you watch if you have time. In essence, a slowing Earth result in an orbit where the length of the day is equal to the entire year.

The Future of the Sun and What It Means for Earth

Posted on March 15, 2015 by robbyks

Right now, the Sun is about halfway through its main sequence stage. It has always intrigued me how the Sun will evolve once it is past this phase. How will the Sun change? What will happen to Earth and the other planets? In approximately 5.4 billion years, the Sun will have exhausted all of its […] Continue reading →

Could the sun live for over a trillion years?

Sun and hydrogen burning: Thinking outside the bubble Yes it can! But not except under unusual circumstances which do not naturally occur in G-type stars as our sun.

Posted on March 14, 2015 by oliviasn

One object in the Solar System that I tend to take for granted proves to be the Sun. Because it is a constant in my life and I always know that I can depend on it rising and setting everyday, I often overlook how powerful it is. The Sun has been shining for 4.6 billion […] Continue reading →
