Have Some ‘Pie’ – View Some Planets

   Saturday March 14th, 3/14/2020, is perhaps better known as Pi Day given that 3.14, the value for Pi, is also the month and day number. Learn more about Pi and see what NASA has planned for this special day at the NASA Pi Day Challenge web site.
   Saturday the 14th, weather depending, is another day this year when you have a choice of planet viewing – all of the six visible planets in fact. In the early morning skies look east and southeast for a line-up of planets ranging from Mercury, to Saturn, Mars, Jupiter, and the 19-day old waning gibbous Moon. In the evening after sunset Venus shines brightly over the western horizon. Venus is near the outer ringed planet Uranus, but Uranus is not considered a naked-eye visible planet in most skies.
   Mercury, Venus, Mars, Jupiter, and Saturn are all visible, but that’s only five visible planets. So where is the sixth visible planet?

Teacher Eclipse Pictures

   Here is a collection of pictures and comments from Science Teacher members of the NSTA (National Science Teachers Association) who viewed the August 21st total solar eclipse from different locations across the United States of America. The State where the picture(s) was/were taken is abbreviated to be part of the picture name – so you could scroll down to the bottom of the picture to see that.
   The caption below a picture starts the sequence of pictures from each teacher. Clicking on any picture will open it into a slide show where you can move forward or backward through the various pictures.
   From Ryan Westberry: Here’s a video I made after watching the totality in Wyoming at Green River Lakes just off the center line. I sent my drone up really high to capture the landscape while also filming our reactions on the surface- and set it all to music.
I did edit the language in the beginning of totality (overcome by that moment) but there are some “Oh S^*t” toward the end that need to be known if anyone plans on showing it. (I’m not promoting that.) I’m just wanting to share in the emotion (I was literally shaking and had tears of joy) and magnitude of watching the event and the love of the science. 🙂

   Here is one of the 360o videos I made while the school yard was filling up with families and the students.

   If you are wondering what do with any eclipse glasses perhaps donate them to the Eclipse Glasses Donation Program – organized by Astronomers Without Borders.

NSTA @ Nashville


   I’m in Nashville Tennessee for the next several days at the NSTA national conference. Planets and stars will still be in the skies but not as easy to see from downtown Nashville as it is where I live. On the morning of April 1st the waning waning crescent Moon will be within a few degrees from Dwarf Planet Pluto. Too dim to be seen without a large telescope it is, nonetheless, a neat idea that when you look toward the Moon you are also looking in the direction of Pluto. It’s out there!
   And here is a sequence of graphics showing the pre-sunrise morning sky at 5:30 am EDT for each day during the conference, and one night view on April 1st showing Jupiter. Both Pluto and the Moon are located just above and to the left from the handle of the teapot asterism for Sagittarius the Archer.

   
   
   

Caution: Objects viewed with an optical aid are further than they appear.

October Qué tal Now Available

october que tal   As the subject line says the October issue is now online and available.
   Many interesting celestial events this month including one minor meteor showers, a partial penumbral lunar eclipse, and conjunctions with our Moon, planets, and stars. In the east before sunrise look for Jupiter to be the point of a right-triangle with the ‘twin’ stars. Mars will pass by the star Regulus in Leo and will have a temporary traveling companion – Comet ISON. Both will be within a couple of degrees from one another but will have very contrasting apparent magnitudes. Mars is naked-eye visible and the comet is not.

Way Back!

Mr. Peabody, His 'Boy', and the Original Wayback Machine

Mr. Peabody, His ‘Boy’, and the Wayback Machine

   Yesterday marked the 20th anniversary, 1993-2013, of the first web site. This was a web site created by CERN, (European Organization for Nuclear Research). In those days before browsers like Netscape appeared web pages were all text and consisted of links to other web pages or web sites – but again all in text, no graphics. The URL to connect with their original web site,telnet info.cern.ch, required that you had access to the Telnet. Commands, e-mail, everything, was all text.

   I have grown up with the Internet, literally. In the mid 1980s I got my first computer, an Apple ][ with a whopping 48K of RAM. This was before the disk drive came out so loading a program meant re-typing the code every time or saving it on a cassette tape. The Modem I had was an acoustical modem at 300 baud. That modem changed as time went by and I am pretty sure I bought every speed that came out up to the 56K modem. It was around then that I finally went broadband!
   There was nothing called the Internet back then, but there was dial-up using a modem to connect to a local BBS. Where I lived in Peoria Illinois Bradley University operated one of the few Telnet systems called the Heartland Freenet. When you dialed in you could then connect via the Telnet (and at broadband type speeds) to other sites on the Freenet. This allowed me, for example, to connect with the Big Sky BBS in Montana where I would work on a Distance Education project with teachers from some Pacific Northwestern states, and Alaska.

   In those days, as a newsletter editor/publisher, I saw some serious value in learning how to write HTML and moved from posting on discussion boards to having my own web site. What I saw was the ability to connect, link, to other web pages. This was important in my thinking because I could more easily reference something, or connect with a similar web page. However the really big change came when the TABLE command was added. Suddenly page formatting became more like desktop publishing in the sense that columns could be created for a more ‘newspaper look’.
   Back then personal web sites were actually a web page or pages and were typically a sub-domain under the ISP’s web name. Many web pages had a URL that included the ISP name followed by /~ (slash tilde) then followed by the person’s name or name for the page. For example on every ISP I used I was /~starwalk, for example, http://www.pei.net/~starwalk (web site no longer at the address). These were not truly websites as we know them today but were very common. In the spring of 1997 I bought a domain name, currentsky.com, and for a couple of years out of a concern for being mistaken for a commercial site I would always follow a post by adding that ‘despite the .com’ this is not a commercial web site – nothing for sale.

   My oldest set of web pages is from January 2000. I had a monster of a disk drive crash sometime the year before and lost all files on even a backup drive. However on the Internet Wayback Machine there are copies that go back to april 1997. Click here to go way back to Qué tal in the Current Skies web site April 12th 1997!

Student Science Opportunities

Iris logo    “Join the Tracking a Solar Storm challenge and guide students as they learn about the Sun’s anatomy, the space weather it generates, and why studying our star is important.
   This challenge is designed around NASA’s Interface Region Imaging Spectrograph, or IRIS, mission. Scheduled to launch in April 2013, the IRIS spacecraft will study the dynamics of the interface region of our Sun’s atmosphere using an ultraviolet telescope and imaging spectrograph. As students participate in the challenge, they will learn about the IRIS mission and the instruments scientists use to gather solar data.
   An educators’ guide to the IRIS challenge is available on the Tracking a Solar Storm website and includes key information for helping students study the sun’s weather, track a solar storm, and predict its effect on Earth. Students will demonstrate what they have learned by collecting data and producing a space weather report.”

whatif   “Candy, soda and other everyday items will be the tools of the trade for teenage rocket makers competing in the What If? Live Student Design Challenge, which was kicked off Tuesday by NASA and the Ahoora Foundation of Plano, Texas. Registration is open through Feb. 28 for the worldwide contest, in which 14- to 18-year-old students will design experimental propulsion systems using materials that are cheap and easy to get.”
