American university professor searches for life outside our solar system

Guinan Apr21

The April 21 session of the 2016 Royal Tyrrell Museum’s Speaker Series is a presentation by Dr. Edward Guinan, Professor of Astronomy and Astrophysics, Villanova University, Pennsylvania entitled “Searching for Life-bearing Exoplanets in our Galaxy.”

Exoplanets are planets that exist outside of our solar system. 

The number of confirmed exoplanets is rapidly growing and now exceeds two thousand. An additional nearly 5,000 exoplanet candidates are awaiting confirmation in the NASA Exoplanet Archive. 

Most of these planets have been discovered by the NASA Kepler Mission, a space observatory launched by NASA specifically to discover Earth-size planets orbiting other stars. Smaller subsets of these planets are similar in size to the Earth and orbit in the (liquid water) Habitable Zones (HZ) of their host stars. 

It is estimated that about ten to fifteen percent of solar-type stars and about twenty to twenty-five percent of the more numerous cooler (red dwarf) stars host Earth-size HZ planets. These planets are of great interest because they have conditions roughly similar to Earth and therefore could be potentially habitable planets (PHPs).

This talk briefly discusses how these exoplanets are discovered; however, the main focus will be on the stellar and planet properties that appear necessary for life to form and develop on their surfaces. New missions and techniques to detect signatures of life (bio-signatures) on these planets are presented along with the feasibility of interstellar missions to nearby HZ exoplanets that could support life.

The Royal Tyrrell Museum’s Speaker Series talks are free and open to the public. The series is held every Thursday until April 28, 2016 at 11:00 a.m. in the Museum auditorium. Past presentations are also available on the Museum’s YouTube channel: youtube.com/user/RoyalTyrrellMuseum. For more information, visit tyrrellmuseum.com.


Council Notes From the regular meeting of Monday, April 18, 2016

Town of Drumheller Crest

Council Notes
From the regular meeting of Monday, April 18, 2016

CAO Ray Romanetz presented the 2016 Provincial Budget Analysis done by Alberta Urban Municipalities Association.
Notable changes are that the provincewide Municipal Sustainability Initiative (MSI) fund shows an overall $50 million reduction compared to a $50 million increase which was pledged, the budget being $846 million for 2016 and is budgeted to remain at that amount for three years. MSI funding for Drumheller has been reduced by $119,150 over last year. Also, the Alberta Community Partnerships grant was cut 50 per cent from $40 million to $20 million, the report calling this "concerning as it impairs regional collaboration," and makes the application process more competitive.
Director of Corporate Services Barb Miller reported on the 2016/17 Provincial Budget's impact on Drumheller. Carbon Tax increases will see a carbon tax of $20/tonne implement as of January 1, 2017 and then increse to $30/tonne on January 1, 2018. This equates to roughly $1.01/GJ in 2017 and $1.517/GJ in 2018. Natural gas is estimated to increase costs to the town of $35,000 in 2017 and $52,000 in 2018, based on the town's annual consumption as the carbon tax is applied at the point where fuel is burnt. Electricity pricing is insulated from the negative impact of the carbon tax until the end of 2020 when the town's final contract expires.
Tax on gasoline is set to increase by 4.5 cents to 17.5 cents a litre due to the carbon tax levy, and this is estimated to cost an addition $2,500. Tax on diesel fuel is increasing by 5.4 cents to 18.4 cents a litre and estimated to add an additional $3,780 annually.
Education Tax will increase provincially by 6.7 percent. The 2016 residential/farmland Alberta School Foundation Fund requisition rate will decrease from $2.50 to $2.48 per $1,000 equalized assessment and the non-residential rate will decrease from $3.67 to $3.64 per $1,000 equalized assessment. Drumheller's total education tax requisition amount for 2016 decreased by $18,820 to $2,702,221 from $2,721,041.

Council moved the second and third readings of Bylaw 6.6 which made changes to the Solid Waste Management bylaw adding a number of contravention penalties which could be issued by Drumheller Landfill staff to individuals who violate bylaws at the landfill. The amendments give Drumheller Landfill employees and Bylaw Services the tools to manage situations of bad behavior or disobedience of laws at the landfill.

Director of Community Services Paul Salvatore presented council with a Request for Decision in appointing Heather Farquharson of East Coulee to the Heritage, Arts and Culture Steering Committee, which was unanimously passed by council. Farquharson has worked with the East Coulee School Museum and has a background in the performing arts.

Councillor Tara McMillan reported on the Valley Bus Society which recently held its Annual General Meeting. User numbers last year averaged 1,108 people per month, averaging 244 trips to the hospital for visits and care, as well as 19 charter trips a month, which make up about half of the VBS' revenue, the other half being fixed bus runs. A new bus was purchased last year and repairs were made on a number of buses. A number of VBS users who attended the meeting expressed the desire for weekend services, but McMillan reported that unless user numbers increase there are not enough funds at the moment.

Youth earn Duke of Edinburgh Awards

Duke

The dedication of area youth was celebrated on April 12 as nine local students were presented with their hard earned Duke of Edinburgh Awards.

There were six youth who were presented with their bronze level awards and three received their gold level award.

“To get gold is unreal, it is pretty awesome, it is the highest level. The only thing more prestigious they could get is an independent medal,” said Constable Craig Nelson, who has helped coordinate the Duke of Edinburgh Awards in Drumheller.

The Program was launched locally in 2011 in partnership with the RCMP.  This self-development program has had an affect on almost seven million young people in 130 countries and Drumheller was the first community in Alberta, and one of five in Western Canada to introduce the partnership. Its first year 14 earned medals, and today it endures.

One aspect of the award is to take on an adventure and alongside the program, Two Wheel View and the RCMP have staged the Badlands to Banff bike tour as an opportunity to fulfill this portion of the challenge. 

“A couple of the bronze winner were on the bike trip and two of the gold winners also participated,” said Nelson. “That is cool that we have that connection there.”  

Nelson sees great value in the program.

“It is giving kids credit for what they are probably already doing. We are encouraging kids to volunteer, to be physically fit and active and to get out of their comfort zone on an adventurous journey and to learn new skills,” said Nelson. “If I go to employ someone, I would want them to do all of those things.”

The awards are also very well recognized.

“If you go to Australia, they are going to know what it’s all about. Any of the Commonwealth countries are going to know, it is internationally recognized,” he said.
