Tag Archive: total solar eclipse 2017


Today’s the big day.  The solar eclipse happens in a few hours.  That orange glow on the horizon?  That’s a 360-degree sunset.  In the States the eclipse can be viewed beginning in Lincoln Beach, Oregon, at 9:05 a.m. Pacific time, and end in Charleston, South Carolina, at 4:09 p.m. Eastern time.  For those in the path of the total solar eclipse, it will last no more than two minutes and 40 seconds.  Parts of 14 states will get the best views: Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina, and South Carolina.  The U.S. will have to wait another seven years for the next total solar eclipse to fall within its borders, on April 8, 2024, but that eclipse vantage point will only stretch from Texas through the Northeast.  The last total solar eclipse viewed from the contiguous United States?  February 26, 1979.  After today’s event, the next annular solar eclipse that can be seen in the continental United States will be on October 14, 2023, which will be visible from Northern California to Florida.  Between 2 and 7 million people are expected to travel to visit the path of totality from border to border today, so expect unusual volumes of traffic.  An estimated 12.2 million Americans already live within the path.

Because of the trajectory of path of totality of this solar eclipse over so many heavily populated cities, this will likely be the most viewed eclipse in the planet’s history.  Before, during, and after the event, eleven spacecraft will be filming the eclipse from different vantage points, plus three NASA aircraft, 50 high-altitude balloons, and the crew of the International Space Station will have unique vantage points (particularly useful for those where uncooperative weather prevents optimal viewing from the ground).  How often will a total eclipse be seen from a specific point on the Earth’s surface?  According to space.com, only once in every 375 years.  A rare event, indeed.  When will the eclipse be overhead for you?  Enter your zip code here to find out.

If you’re asking “what eclipse?” then you will not likely have time to acquire the required protective glasses in time for the event, although several locations still had glasses available this weekend.  Check your local grocery stores and libraries and they may be able to help, but start early Monday.  Every eye professional, scientist, and medical professional has advised of the serious risk of partial or total blindness Monday if you look at the Sun without the specific recommended eyewear, both before and after the totality of the eclipse–those seconds that the Moon is directly between the Earth and the Sun from your location when the Sun is completely blocked.  Review this material at planetary.org for detailed information.  Scan this checklist into your phone or print it out for a last-minute reminder–the time will fly by so don’t wait until it’s too late to get the information you need:

cernan-2017

Yesterday the last man to walk on the Moon, Apollo 17 commander Capt. Eugene Cernan, passed away at age 82.  Of the 24 men who visited the Moon and the 12 that walked on its surface Cernan leaves only six remaining men who actually walked on the Moon’s surface: Buzz Aldrin (Apollo 11), Alan Bean (Apollo 12), Dave Scott (Apollo 15), John Young (Apollo 16), Charlie Duke (Apollo 16), and Harrison Schmitt (Apollo 17).  A three-time space traveler, Cernan was the pilot on Apollo 10 and had previously flown on a Gemini mission.  He served as backup crew for Gemini 12, Apollo 7, and Apollo 14.

“Curiosity is the essence of human existence and exploration has been part of humankind for a long time.  The exploration of space, like the exploration of life, if you will, is a risk.  We’ve got to be willing to take it,”  Cernan said.  Cernan passed away on the annual day America observed the contributions of Reverend Dr. Martin Luther King, Jr., and he, too, recently recounted a dream.  “I was just a young kid in America growing up with a dream.  Today what’s most important to me is my desire to inspire the passion in the hearts and minds of future generations of young men and women to see their own impossible dreams become a reality.”

The best tribute to Cernan and his contemporaries is the continuing exploration and discovery missions of NASA, which will be the subject of several documentaries this year on PBS.  In particular, August will be a big month for space aficionados.

The documentary The Farthest will celebrate the 40th anniversary of the Voyager space program.  As discussed extensively previously here at borg.com, the Voyager probes continue their role as the farthest humans have stretched their technology into space.  The only objects to ever enter interstellar space are Voyager 1 and Voyager 2.  Voyager 2 was the first to launch forty years ago, on August 20, 1977.

In the short days of winter, even if you are in the city with the imposition of urban skylights, the night sky seems to release a better view of the stars.  Something about the snap of the cold and the clean smell of the air almost lures you to stay outside a little longer when the darkness appears as an almost otherworldly blue.  But how long will we be able to have this kind of view of the universe?  It’s this kind of moment that an astronomer and artist has captured in a series of spectacular posters, promoting educational viewing events at the National Parks.

Dr. Tyler Nordgren, artist, astronomer, photographer, professor, and national parks “Night Sky Ambassador” is one of those multifaceted people who shares his knowledge with others, giving us all an appreciation for the world around us, and beyond.  His 2012 poster series first spread in a colorful and compelling way word of ranger naturalist programs at the U.S. National Parks Service, including the solar eclipse.  Dr. Nordgren created a series of retro-style travel posters beginning in 2005 exploring a “what if” of planetary travel referring to a “United Nations Department of the Exterior.”  His 2014 Milky Way “Half the Park is After Dark” posters stand out as uniquely magical.  All feature a blue and white color scheme, a national park location, and a constellation or star view visible overhead.  Although they immediately recall–and were inspired by–the famous Art Deco Works Progress Administration and Department of the Interior posters from the 1930s-1940s discussed previously here at borg.com, his 44 designs form their own museum gallery of wonder.

Dr. Nordgren’s latest project?  The August 21, 2017, solar eclipse.  According to Dr. Nordgren, “Every single man, woman and child in North America will be in the shadow of the moon together on that day and never before has a total solar eclipse passed over such a densely populated country for over 2000 miles.” Dr. Nordgren has created a new set of poster images, featuring 22 designs of varying style influences, each highlighting the total solar eclipse coming this year on August 21–not to appear again until April 8, 2024.  As the appropriately themed mod style poster for Oregon declares, this will be the first such eclipse since 1979.  Dr. Nordgren’s Willamette Valley design evokes those colorful fruit crate labels used throughout the early and mid-20th century.
