As I’m sure you probably know, this is the very day that NASA’s Rosetta spacecraft has landed on a comet to peer into an object that has fascinated and terrified humanity for thousands of years! If you click on the link below, you can see the official NASA page of the mission, with pictures, a timeline, and video coverage of the mission.
In honor of this momentous occasion, I’ve created a short presentation for you about comets. Feel free to use it in class, but please give me credit!
I’ll be writing more later in the week about the significance of this mission, but for now, enjoy this presentation, and enjoy watching this incredible mission online!
Here are my best posts on Halloween:

I found a great video from DeepSky Videos.com, where an astronomer probes the depths of a beautiful dwarf galaxy that is encircling our own like a comet. Only recently has NASA been able to penetrate this galactic cloud, and here are some of the facts about this unique object:

Today the GOCE European Space sattelite came crashing down to the South Atlantic Ocean! Scientists caution that there is a huge garbage dump of sattelites orbiting our planet and that this could happen again at any moment. The lesson here appears to be: “Space to Earth, CLEAN UP YOUR SKY!”
Tonight is the second night of the Harvest Moon, the time when the Moon rises earlier than ever before, right before the Autumnal Equinox.
As I mentioned in “The Tale of the Lucky Red Moon,” Harvest Moons have a profound cultural significance. China has its own Mid Autumn Moon Festival that tries to unite cultures under one Moon. You can read about this in a wonderful article at Earthsky.org
So get out tonight and enjoy this rare Harvest Moon! I plan to take a few pictures with the telescope if it’s not too cloudy here at Primland.
Hello fello triscadecaphobs! In case you wonder what that big word means, it means “fear of Friday the 13th.” An estimated 17 million people fear this very day. There is actually a long and complicated history to the fear of this day, especialy in our own culture, and I set about trying to lay this fear to rest using my knowledge of history, mythology, and of course, astronomy.
Cultural/ Historical significance of Friday the 13th.
The number 13 itself is considered unlucky for a number of reasons, especially in Western Christianity- in the Bible the disciples and Jesus add up to 13, which eventually led to the betrayal and death of the leader, (which occured on a Friday). In addition, on October 13, 1307 the Pope ordered for the murder of the hallowed Knights Templar, the most powerful Christian knights in the world.
The fear of Friday the 13th itself might have formally begun in the 19th century, with the death of Rossini, the celebrated composer of “The Barber of Seville.” On his death bed, the composer remarked that he always regarded Fridays and the number 13 as unlucky. As is often the case, this quote probably got repeated over and its influence multiplied into a whole superstition. By the way, wikipedia lists a number of famous people who have died on Friday the 13th, including Julia Child and Tupac Shakur.
So, what does this have to do with Astronomy?
Richard Beveridge, in his paper “Friday the 13th and the Mathematics of the Gregorian Calendar,” points out that there is an innate fear of Friday the 13th built into our culture from the fact that we base our time tables around the number 12- the 12 months of the year, the twelve signs of the zodiac, etc. This creates a feeling of otherness and other worldliness to the number 13. In addition, with the way we add leap years every four years, Friday the 13th occurs at random intervals, and it is very difficult to predict. Again, we fear things we can’t predict or control, which is why we fear even a date on the calendar.
Good news about Friday the 13th.
NASA recently predicted an asteroid would pass harmlessly over the Earth on Friday, April 13th, 2029. If this asteroid would pass too close, it could destroy an area the size of Texas! So I suppose you could say that some good things can come on Friday the 13th, even if they are things that don’t happen.
Well, that’s what I know about Friday the 13th. Hope some of your fears are allayed.
Not only is this the biggest Moon of the year, it’s also one of the most interesting. June 23rd’s full moon is classified as a “Strawberry Moon,” or “Rose Moon” It was called Strawberry by the Algonquin Native Americans because they knew this full moon was an ideal time to gather fruit. To learn more about this particular full moon, I’ve posted a link to a video created by the good folks at “The Farmer’s Almanac”, a trusted astronomy resource for over 100 years.
So I hope to see some of you down at Primland to look at this beautiful full moon. I know I’ll be training the telescope on it!
Like most of us in this economy, NASA has had to make some budget cuts. When they released their 2014 budget, it cut over $55 million from the previous year. Planetary studies have been hurt the most with 300 million cut from the budget. Looking at this, it’s clear that studying our solar system is just not a priority anymore; NASA is taking new directions with its research and some of its new plans are quite exciting.
For Example, NASA is increasing its funding to support Earth science; tracking man made and natural changes to our planet, including pollution and climate changes. The idea is that hopefully learning more about how to protect our planet and to protect ourselves.
In addition, there is also a program in place to start manned missions into space once again. I’ve written about this before when I mentioned the Orion Spacecraft, the first manned spacecraft designed for interplanetary orbit in 30 years. NASA is already building the space capsule, and the whole project should be finished by 2021.
BUT, there is one item on the NASA budget that seems right out of science fiction- The capture and mining of ASTEROIDS!
That’s right, President Obama approved a new project designed to send a special craft out into space for the purposes of finding and capturing a Near-Earth Asteroid (NEA), and then bringing it back down to Earth to study, and eventually mine it for its contents. This might sound like something out of a James Cameron movie, but it really is part of the NASA budget, and the project is getting underway as we speak.
So why mine asteroids? To answer this question, I’ll break down the arguments and, (to continue with the Sci-Fi theme I’ve begun), I’m going to list them one by one, and name them after some awesome Sci-fi movie titles.
1. The Abyss/ Avatar-
According to scientific estimates, one asteroid may contain over $20 TRILLION dollars worth of precious metals, as well as iron, nickel, and cobalt. Ultimately, it might improve NASA’s budget and the world economy greatly to invest in asteroid mining. Plus, unlike Avatar, all of these asteroids would be uninhabited, making mining comparatively easy from a socio-political standpoint. Still, as you can see from the video above, to make this plan economically viable on a large scale we would need to develop vastly superior rockets, to keep the cost of sending rockets up into space all the time lower than the profits reaped from the asteroids themselves. As far fetched as this idea may seem, companies are already working to make it a reality. Imagine NASA beginning a new industry as unlimited as the universe itself!
2. Titan AE
If our planet were to suffer a cataclysm, (which could literally happen any day now), we will need to find a new way of getting water, oxygen, and the ingredients to create plant life. In addition to precious metals, asteroids also contain all of these. Bits of oxygen and hydrogen are locked up within the rocks. In addition, we know that asteroids contain ingredients for life, since 3.5 billion years ago, they helped develop life on our own planet. Therefore, if we ever need to leave the Earth, it makes more sense to mine our raw materials from asteroids, rather than taking everything with us. Of course, getting us off the Earth, is a much bigger problem:
As the Russian meteor explosion grimly reminded us, Earth could literally be hit by an asteroid at any time without warning. This is why the primary goal of the Asteroid Retrieval project is to study asteroids and determine how best to combat a potential threat. Lest we forget, an asteroid destroyed entire species on our planet 65 million years ago, and we need to be careful to make sure it doesn’t happen to us (cue the dramatic music).
So there you are, the major reasons why it’s a good idea to find asteroids and bring them back here. We eagerly await NASA making this project a reality, so that they make space a safer and more profitable place to live. As one more treat, here is a NASA animation of how the project might look, with dramatic Hollywood music underscoring for good measure.
In addition to running this blog and giving nightly astronomy tours, I am also working on developing a kid’s astronomy program for the resort. In my quest to make astronomy fun, accessible, and interactive for young people, I came across some valuable free resources that I’d like to share with you. Obviously there are hundreds of blogs, podcasts, video channels, and websites out there and I could never share them all, so if you like this post and think something should be added, let me know! I’d be happy to make this a new page on the blog and follow up weekly with new resources.
So here is a short multimedia collection of links that you can show to your young ones to get them excited about space:
Deep Sky Videos– An excellent channel, not only for astronomy, but for science all together. It features great pictures by professional astro-photographers and lots of valuable data.
NASA TV- Here’s NASA’s official YouTube Channel, which provides you with simple, clear explanations of what our space agency is doing. Sometimes they interview astronauts on the International Space Station, and get them to talk about life in space.
NASA JPL Live This is not Youtube, but a live feed from NASA’s Jet Propulsion Laboratory. Whenever there is any kind of live event at NASA, such as the docking of a spacecraft, or live pictures from Mars, you can access it with this link!
Exoplanet- A free app that allows you to keep track of any new planets discovered outside our solar system. You can use your mobile device to find each planet in an interactive map of the galaxy, zooming at warp speed to newly discovered worlds.
Sky Viewer- This app tells you exactly what planets and constellations you are looking at by overlaying names and a connect-the dots pattern over the night sky. A GPS compass keeps track of where you are, and you can see the stars using the display. There is a pay version that also shows you more planets and keeps track of satellites, but the free version is a nice way to learn the constellations and keep track of where you are in the sky.
NASA Space Weather Map (Android App only)
View near real-time images of outer space from current NASA missions. Learn about weather near the Sun, Solar Wind, Magnetosphere, Aurora, and Heliosphere from scientists who study them
I did find some neat pay apps from this website too, just in case you aren’t satisfied with the free stuff:
Astronomy.com– The official website of Astronomy Magazine, loaded with pictures, articles, and tips for amateur astronomers, and yes, there’s a kids’ page.
ISS Tracker- A website that allows you to know where the International Space Station is at all times!
NASA’s JPL Planet Quest- A great interactive site which teaches kids about planets beyond our solar system, by allowing them to create one, studying the ideal conditions for creating life in the universe.
The Curiosity Rover’s Twitter Page- Updates from the mission, written in the first person by the robot.
Kids Needs Science (Tumblr Page)-Full of beautiful pictures of space objects and links to articles.
International Space Station Facebook -Regularly updated with videos, pictures, and news articles.
So there’s a rough start to the vast world of astronomy for kids on the web. Like I said earlier, I’d be happy to post any of your suggestions, or turn this into a regular feature on the blog. Let me know in the comments. In closing, just to show you how far we’ve come with online education, I’d like to post an oldie but a goodie- Bill Nye the Science Guy explores comets and meteors:
