Welcome to my astronomy blog. A short introduction to start this off.
My name is Bruno Ferreira, also known as Dr. Plim, and among many other things I’m an Astrophysicist. I obtained my PhD from the University of Florida in Gainesville in April of 2010.
I’m currently teaching online at the Rasmussen University and will be using this blog to post some of the astronomy/astrophysics-related news and insights that I find interesting for my students and for anyone else who stumbles upon it.
Some useful information: It is March 2012 and I am still updating this website. You may notice that the blogs entries are from 2010 or so, this is simply so that I can keep the blog entries in some kind of order. Blog entry number 1 is at the very bottom of the page and it is for Week 1 of the astronomy course.
If you find some really awesome information that you would like added here then please email me or send me a comment.
If you find some error/correction then please email me or send me a comment.
Live long and prosper.
Planets In Our Solar System
We scientists have theories for the formation of the Universe, the formation of galaxies, the formation of stars, the formation of solar systems and the formation of planets. And yet, there is still so much that we really don’t know or understand. Let’s look at some interesting results when studying our own planets.
Two decades ago we measured Venus’ rotation period to be approximately 243.015 Earth-days; recently, with the Venus Express Orbiter, the European Space Agency made accurate measurements of Venus’ rotation and realized that it is rotating 16 minutes slower!

Hello Students of the Universe,

Some of you have chosen to do your research projects on the Aurora Borealis. Great, that is definitely one of my favorite topics.

Just recently there was a very good interview on NPR about this magnificent phenomenon. Tom Ashbrook interviewed I strongly recommend that you listen to this podcast. LINK
Guests on the show were:
“Justin Kasper, astrophysicist in the Solar and Stellar X-Ray Group in the High Energy Astrophysics Division of the Harvard-Smithsonian Center for Astrophysics. His latest project is leading the Solar Wind Electrons Alphas And Protons (SWEAP) investigation on the Solar Probe Plus spacecraft.
Howard Singer, chief scientist at NOAA’s Space Weather and Prediction Center.
Frank Koza, executive director of operations support at PJM Interconnection, which is a regional transmission organization that coordinates the movement of electricity in 13 states.
Chad Blakley, aurora borealis photographer, who runs the website Lights Over Lapland.”
