Asteroids

I must admit, despite all of the family vacations we took out west over the years when I was a kid, to the best of my knowledge we never saw a crater. It’s actually only been since we got our family cabin that I think I really began to wonder about space and what is out there.

So I found this article quite interesting about asteroids and the apparent increased frequency of them, according to this article entitled “We are living in an era of high frequency asteroid strikes” by Bryan Nelson over at Mother Nature Network.

Sort of reminds me, in a strange sort of way, how we’re way past the average time between an eruptions at Yellowstone National Park. Kind of scary when you think about it.

Dark skies

So excuse me if you heard this one. I thought I posted this article before but maybe I haven’t. One of my favorite things about the earth is actually the night sky. I love it when we’re up north on vacation and you can look at the sky.

I’ve often said to my kids that the sky looks so full of stars, like you couldn’t stick another one up there because there’s no room. Anyway, the article is entitled “The World’s 11 Certified Dark Sky Reserves, Where the Stars Run Riot ” by Melissa Bryer over at Treehugger.

When I read this article it actually reminded me of a book I read at the library a few years back but I can’t for the life of me remember the title. Perhaps that’s a re-post for another night. First I need to go back and find the book.

150 Migration paths (simultaneously)

So I written several post’s on the migration paths of various animals but here’s an article and video that talk about and show the migration paths for 150 animals, all at the same time. The article is entitled “Watch 150 Animal Species Roam the Globe in This Amazing Migration Animation” by Melissa Breyer over at Treehugger.

There is also a link in the article to Movebank, an online database of animal tracking data where researchers can share their data. I think the article does a really nice job of showing how other species work in harmony with the planet, rather than against it.

Pluto

I guess I’m one of those who wishes that Pluto was still a planet (and not a dwarf planet). Over the last couple of days, I’ve seen the pictures of Pluto and it’s moon Charon. They really are amazing.

Tonight I watched the Chasing Pluto show on at PBS, talking about the New Horizons spacecrafts journey from Earth to Pluto.Then I watched a video over at Grist entitled “Watch Neil deGrasse Tyson and Stephen Colbert fight about planets“.

Good stuff and I think Neil deGrasse Tyson is a great scientist but I still consider Pluto a planet. I guess I’m old school.

View from the top

It’s a view of the earth that most people never see. Check out the article and short video about the view entitled “Earth, the Marvelous Blue Orbover at the New York Times by Dennis Overbye.

As the nights get brighter

I get planet guides from time to time courtesy of the great people over at Earthsky and usually I just sort scanned them over but this month (after seeing the “January 2015 Guide to the Five Visible Planets“) I actually got some great glimpses. I might have even seen Saturn.

First on my metrolink ride and then in the car on the way home. I also saw a few nice shots of the moon and even one or two the stars outside my house.

Sweet!

Looking up at the night

As I was looking up at the beautiful moon tonight, I was reminded of a nice article in my local paper (St. Louis Post-Dispatch) on a building somewhat unique and dedicated to the stars and planets up above.

The article is entitled “After Five-Year Break, Planetarium Gets Color Again” by David Hunn. It’s actually connected to another amazing building here in St. Louis, the St. Louis Science Center. So if you’re ever in town, they’re well worth the time.

Twinkle, twinkle little star!

Solar & Tsunami, two words I would have never put together

So while we’re still on the topic of the sun, I have to say that I never would have imagined that I would see the those two words in the same sentence but here they are. The article is “Solar Tsunami Used to Measure Sun’s Magnetic Field” over at Science Daily. Of course I think what is amazing is how much we’ve learned about the sun despite how far away it is and how hard it is to get close to it. The book I read awhile back, The Sun’s Heartbeat and Other Stories from the Life of the Star that Powers Our Planet by Bob Berman only made it so awe inspiring to me.

Hot! Hot! Hot!

So it looks like the sun’s getting a little excited for summer as well as this article “NASA Sees Giant Solar Wave Erupt from the Sun (Video)” talks about over at Yahoo! via Space.com.

I also wanted to include another article and while not on the Sun, but rather the Earth, talks about a fact found in Bob Berman’s book, “The Sun’s Heartbeat and Other Stories from the Life of the Star that Powers Our Planet” on how the sun actually has an inner core.

This article talks about the inner core of the Earth and is entitled “Earth’s Core 1,000 Degrees Hotter than Expected” by Elizabeth Howell at LiveScience.

Our home

My kids have always enjoyed looking at the other planets as we gaze out into the sky but this article over at the New York Times entitled “The Enigma 1,800 Miles Below Us” by Natalie Angier at the New York Times was a great read about our own home, planet Earth.

Night Time!
