Climate Change

Posted on March 12, 2016 by Michaela Thomas

Climate change is unfortunately vastly overlooked as a serious threat to our species today. NASA itself has a detailed list on its website devoted to the current evidence of climate change. The list includes the following phenomena: Sea level rise Global temperature rise Warming oceans Shrinking ice sheets Declining Arctic sea ice Glacial retreat Extreme […] Continue reading →

HW #B4 – To Blink Or Not To Blink

Posted on February 16, 2016 by evinske

On a warm night this summer on Edisto Island, SC, my friends and I took to the beach to go shrimping. The after-dark escapade turned into a feeding frenzy, reaping monstrous crustaceans with beady, red eyes. The younger kids eventually took turns in the water, and I sat on a sand dune and looked up at the clear […] Continue reading →

Spectra Across Spectral Types

Posted on February 16, 2016 by briannagalgano

One of the beautiful aspects of the universe is that not every celestial object is exactly the same. The majority of stars spend their lives on the “main sequence” in which they have stable volume and continuously undergo hydrogen fusion. Astronomers use a classification system based solely upon the temperature of a star, assigning each […] Continue reading →

I’ve got this giant telescope and I don’t know where to put it: a guide for all your telescope placement needs.

Posted on February 16, 2016 by d51blog

Hey, where should I put my giant telescope? Ideally, you would put your telescope into space! Space is most advantageous for observing the stars because most types of non-visible light are blocked by our atmosphere; this wider spectrum of detectable light allows for more detailed study of some of the universe’s greatest extremes. Some of […] Continue reading →

Tides can be Fun(dy)

Posted on February 16, 2016 by Gabi Grys

Anyone who has spent the day at the beach has experienced the changes of the tides. Few of us, however, have ever seen anything like the Bay of Fundy, a body of water between New Brunswick and Nova Scotia in Canada with the largest tidal range in the world. Within twelve hours between low and […] Continue reading →

Why do we have tides?

Posted on February 16, 2016 by nedastro2110

Today I want to talk about tides! Above is this video of Clovelly, England and the drastic tide that they experience day in and day out, especially when it is spring tide, meaning the moon and sun’s tidal forces line up to create even more drastic tidal forces. What is amazing about that video is […] Continue reading →

Gravity Waves and the Graviton

Posted on February 16, 2016 by 2016spaceodyssey

So physicists have recently announced the discovery of Gravitational Waves, but what does that mean for the Graviton?  Similar to how protons and electrons carry electrical charge, it is theorized that the Graviton carries, you guessed it, gravity.  Because it is a subatomic particle it is more of a focus for particle physicists than for […] Continue reading →

Stonehenge

Posted on February 16, 2016 by Chloe

Stonehenge. Photographer: Howard Ignatius.  Stonehenge of southern England is one of the most famous Neolithic structures and burial grounds in the world. Construction on Stonehenge started in 5,000 BCE and continued for 1,500 years.  Its eerily arranged stones, transported from up to two hundred miles away from the site, are an iconic draw for the […] Continue reading →

Tides+Moon…Relationship?

Posted on February 16, 2016 by segalastronomyblog

If you spend an entire day at the beach, it is pretty obvious to notice that the tide changes throughout the day. Sometimes it comes up all the way to your feet while you lay in your beach chair, while other times the tide can be so low it seems like the water is a […] Continue reading →

Using the Stars to Navigate

Posted on February 16, 2016 by Alex Pratte

c For my third blog, I came across a mental floss article giving some helpful tips on how to navigate at night by looking at the stars. As we all know people have been using the stars to navigate from place to place for really long time, so it seems like something pretty handy to […] Continue reading →
