The
ballots are counted and a winner in hand for the National Radio Astronomy
Observatory’s (NRAO) second annual image contest.
It
was this view of an immense dusty gas bubble in our own Milky Way galaxy that
napped first place and $1,000 in the NRAO’s contest.
The
bubble is the result of wind and radiation spewed from a few hot and massive
stars and immense explosions from stellar supernovae. It sits about 30,000
light-years from Earth towards the constellation Vulpecula, and spans 1,100 by
520 light-year patch of sky.
An
imaging team led by the University of Manitoba’s Jayanne English captured this
view of the bubble using data from the Very Large Array in New Mexico and the
Green Bank Telescope in West Virginia. English shares the $1,000 prize with
collaborators Jeroen Stil and Russ Taylor, both of the University of Calgary.
Taylor
led a survey that used the Very Large Array to take some 3,000 observations
over 260 hours to help build this view of the bubble.
"We
congratulate Dr. English for producing an outstanding image that beautifully
illustrates the power of our radio telescopes," said NRAO Director Fred
K.Y. Lo in a statement.
NRAO
officials announced the award on Oct. 16, 2006.
