In March, Sharon Odell provided an update on the work and prospects of the RASC Ottawa Diminion Observatory Subcomittee's work to preserve and conserve the original observatory, and also presented a video testimony to "Courage and Passion: Canadian Womern in Natural Sciences" during the break. Following that, astrophysicist Dr Matt Caplan of the McGill Space Institute took the audience into the nasty, throbbing nuclear waffles pasta at hearts of neutron stars that yield gold (and other, more useful stuff), and highlighted the "remarkable agreement between theory and more theory" underpinning these discoveries. See the video here.

  

Following, at the April meeting, Dr Janet Tulloch of Carleton University continued to fascinate with the presentation started back at the February meeting on the "Outstanding Standing Stones" eatsblished in neolithic Orkneys and especially their solsticial alignments, and that can be found here.

Here are the Observers' Challenges for May 2019.
 
Beginner Challenge Intermediate Challenge Advanced Challenge Lunar Challenge

M101
(NGC 5457)

a.k.a the Piwheel Galaxy, is a face-on "grand design" spiral galaxy distanced 21 million light-years (six megaparsecs)[3] away from Earth in the constellation Ursa Major.

NGC 4361
 
NGC 4361 is a planetary nebula in the constellation of Corvus.

Hickson Compact Group 50

Hickson 50 is considered the most difficult of the Hickson galaxy groups to observe. It is estimated by some to be 2 billion light-years in distance, based on red shift measurements.

Lambert R
 "Gohst crater" Lambert R
Just to the south of Lambert's ramparts is the lava-covered rim of Lambert R, a crater that is almost completely covered by the mare. The diameter of this ghost crater is larger than Lambert, but it is difficult to spot except when the Sun is at a very low angle, casting long shadows.

I'd like to see more people submit reports than did this past month -- I encourage everyone to participate, not just imagers! You can submit reports by way of images, sketches, or even without any imagery, you can come up and give a verbal report that perhaps includes the conditions you made your observations under, and the details of the equipment you used -- and of course a description of the object as you observed it! Be sure to send them to me for inclusion in the next meeting at meetingchair[at]ottawa.rasc.ca

M82
(NGC 3034)

a.k.a the Cigar Galaxy is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major.

M109
(NGC 3992)
 
is a barred spiral galaxy exhibiting a weak inner ring structure around the central bar approximately 90 million light-yearsaway also in the constellation Ursa Major.

Galaxies Beyond M44

Beyond the Beehive Cluster in Cancer lie at least 9 galaxies in which can be spotted in large scopes.

 

 The Hortensius Dome Field
 
formed as a result of the Moon's own internal volcanism and are similar to shield volcanoes in Iceland, Hawaiʻi and Olympus Mons on Mars, formed when highly fluid lavas erupt through a central caldera onto the surface.

The video of February 1st meeting of RASC Ottawa Centre, available on YouTube,  features guest speaker Dr Janet Tulloch of Carletone University reviewing the astronomical as well as religious significance of solsticial alignments in neolithic monuments in Orkney; science communicator and astrophysicist Jesse Rogerson reviewed the solar system's first known interstellar interloper, Oumuamua and the regular observers reports and monthly sky news.

The video of the January 4th meeting of RASC Ottawa Centre is to be found here on YouTube. The usual fascinating updates from members, including Dan Vasiu's account of astronomy outreach work in Romania, was complemented by guest speaker Dr Robert "Lauchie" Scott providing an extensive overview of Canada's research and development into situational awareness for its space assets such as RadarSat.
