We had great clear skies on Friday, June 10 and ended up with a small, but enthusiastic collection of astronomers looking at the Moon, Jupiter, Mars, Saturn, M13 and a variety of other deep sky objects!
Join us at NSO on Friday, July 8, starting at 8:30 PM for our next star party! Check this website for late-breaking news about the weather! We hope to see you there, and invite your friends!

Here is a photo of the Blood Moon Super Eclipse on September 27, 2015 taken with NSO by NKAF educator Brad Vietje. As he remarks - "Pretty tough target for a 17" telescope! The partial phases would be better with a DSLR and a 600mm telephoto -- just too bright for the telescope ..."
Check out this time lapse video of the eclipse made by NKAF docent Bill Vinton:
"This video was created by taking a series of 53 stills at about 5 minute intervals through an Olympus E510 DSLR at the prime focus of my 120 mm f/5 refractor in Waterford, VT. Exposures ranged from about 1/2000 sec for the brightest full moon to 2 sec for totality. The images were aligned and rotated, and adjusted for brightness and contrast.
The telescope mount lost its calibration near the middle of totality, and I didn't dare take the time to re-calibrate; thus some of the long-exposure images ended up a bit blurry.
Notice that the angles of the shadow at the start of the eclipse and at the end of the eclipse differ. Most of the motion is due to the moon moving through the shadow of the earth, and the diameter of the earth's shadow is about 4 times larger than the moon. The moon did not pass through the middle of the shadow - if you think of the shadow as a clock face, then the moon entered the shadow at about "2:30" on the face (edge of shadow almost vertical) and left the shadow at about "7:00" on the face (edge of shadow almost horizontal). This off-center trajectory also led to the bright glow around the lower edge of the moon during totality."

We were honored during the summer of 2014 to host young science minds from across VT at our Space Camp in Peacham. Director Brad Vietje and camp Chef/Mom Linda Ide did an amazing job keeping everyone's minds and stomachs filled. Field trips this year included the Fairbanks Museum's planetarium, Dartmouth College's Dept of Physics and Astronomy and Shattuck Observatory, and for the first time we traveled to the AMC Highland Center to work with Carthage College professor Doug Arion.
Special thank you to our awesome campers, their families, our field trip hosts and the Green Mountain Retreat Center.
Additional gratitude is due to our financial aid sponsors - the St. Johnsbury Rotary, Chroma Technology, and our generous local donors. We are committed to making opportunities possible despite financial challenges, and your support makes that possible. Thank you.

Supernova 2014J in M82
Imaged at NSO by
NKAF President Bill Vinton and Educator/Board member Brad Vietje on 1/23/14
Astronomers around the world were excited to see the eruption of a Type Ia Supernova in the (relatively) nearby galaxy M82 (11.5 million light years distant), known familiarly as the "Cigar" galaxy because of its unusual appearance. First observed on January 21 by Dr. Steven J. Fossey at the University of London Observatory, the supernova was subsequently found to be evident in previous observations of M82 taken as early as January 15 . On January 23, when the photograph was taken, the supernova had brightened to magnitude 11, rivaling the brightness of the entire galaxy. It is likely that the supernova will continue to brighten over the next few weeks, perhaps to magnitude 8.5, easily visible with binoculars.
A Type Ia supernova occurs when a white dwarf in a binary star system steals enough mass from the companion star to initiate a sudden, massive runaway fusion reaction in its core that disrupts the entire white dwarf. By contrast, a nova explosion, such as the one that happened this summer in the constellation Delphinus, represents a similar, but much less energetic process, because the rate at which the white dwarf accretes mass from its larger companion is smaller, causing only a relatively gradual surface fusion explosion that does not disrupt the entire star. Another type of supernova, termed Type II, occurs when a heavy star at the end of its life undergoes a sudden catastrophic collapse and explosion.
The luminosities of Type Ia supernovae are quite uniform because of the similarity of the white dwarf progenitors that explode. Thus, they serve as reliable "standard candles" that allow accurate determination of distances to far away galaxies. Observations of Type Ia supernovae in distant galaxies led Saul Perlmutter, Brian Schmidt and Adam Reiss to conclude in 1998 that the expansion rate of the universe is actually increasing. This momentous discovery led to them being awarded the 2011 Nobel Prize in physics.

Spectral Observations of
Nova Delphini 2013
Over the past two years, docents and students have developed a sophisticated ability to take attractive photographs of astronomic objects using our wonderful telescope. Now, our initial spectroscopic images represent a new phase in the evolution of our ability demonstrating the potential of Northern Skies Observatory for involving students in authentic scientific research. We have much to learn about the techniques for taking, processing and analyzing such images.

NKAF Docent Bobby Farlice-Rubio continues to educate VT on "The :30" on WCAX, and recently he mentioned his ongoing work at NSO imaging comet ISON.
