Cuddling Up in a Quilt of Gamma-ray Stars
The Compton Gamma Ray Observatory may be gone, but its memory lives on --
in a quilt museum in Harrisonburg, Virginia. Unbeknownst to Compton
astronomers, a retired couple in rural Virginia took two gamma-ray
images that their son received from NASA way back in 1993 and turned
them into spectacular quilts.
One image, of the Crab and Geminga pulsars, is on display through
September 18 at the Virginia Quilt Museum. The second, of a gamma-ray
quasar called 3C 279, graced the celebratory symposium of the
Compton mission on July 19 at NASA Goddard Space Flight Center in
"I can't say I know much about quilt-making, but these are fabulous
reproductions of the original Compton images, right down to the
smallest detail, or data point," said Dr. Neil Gehrels, a Goddard
astrophysicist and project scientist for the mission. "We could use
them as view graphs at meetings if the electricity should ever fail."
The cosmic quilt makers are Rose and Albert Costanzo, a retired couple
who manage a Christmas tree farm in Elkwood, VA. In their ten years of
quilting, they have never made an astronomy-themed quilt. Nor do they
consider themselves amateur astronomers. Mrs. Costanzo was simply
struck by the gamma-ray images that her son showed her, captured by a
Compton instrument called EGRET.

Mrs. Costanzo wrote to Goddard in June after hearing about the end of
the Compton mission via controlled reentry over the Pacific Ocean.
"I saw in the paper that their satellite was deliberately crashed in
the ocean," said Mrs. Costanzo. "I just wanted them to know that one
of EGRET's many images can now be seen as a quilt hanging in a
museum." EGRET is short for Energetic Gamma-Ray Experiment Telescope,
one of four main instruments aboard Compton. The Compton Observatory,
launched in 1991, burned up in the earth's atmosphere during a
controlled reentry on June 4, 2000.
Mrs. Costanzo first caught the astronomy bug when images from the
Hubble Space Telescope of swirling and bulging false-colored galaxies
began to appear in popular news magazines such as Time and
Newsweek. Early attempts at quilting these images didn't go far.
In 1993, the Costanzos' son, Daniel, now a volunteer coordinator for
the Albert Einstein Planetarium at the National Air and Space Museum,
thought that new Compton images he had seen would lend themselves
perfectly to a quilt design. Such gamma-ray images are blocky or
pixilated, by nature of the telescope technology and the physical
nature of gamma rays.
Daniel Costanzo contacted Dr. Dave Thompson, a Goddard astrophysicist
who works closely with EGRET data. Dr. Thompson quickly sent off two
photographs of EGRET images to Daniel, not knowing what they would be
used for. That's the last that Dr. Thompson heard of the
Costanzos... until June 12, 2000.
Mrs. Costanzo letter to Dr. Thompson -- written in an "FYI" manner --
contained a photograph of the Crab and Geminga quilt. The EGRET team
members at Goddard were so impressed that they asked the Costanzos to
join them at the Compton symposium and to bring the second quilt, not
yet on display. The Goddard visitors center would also like to display
both quilts. "My husband and I are completely bewildered by these
snowballing events," said Mrs. Costanzo. "This is certainly exciting."
With the success of the Compton quilts, the Costanzos plan to attempt
yet another celestial image, perhaps from the recently launched
Chandra X-ray Observatory. Chandra has already captured hundreds of
dramatic images of supernovae and flaring stars.
Rose Costanzo is a former school teacher and one of the first women to
graduate from St. Bonaventure University. Albert Costanzo, a veteran
of three wars, is a retired Army colonel and was a West Point
classmate of Edwin "Buzz" Aldrin. Mrs. Costanzo designs and pieces
together the quilts; her husband helps with the final stitching, which
is called quilting.
