the 2.4-meter telescope |
The Magdalena Ridge Observatory(MRO) sits on South Baldy Ridge in the Magdalena Mountains, about 30 miles west
of Socorro in central New Mexico and 10,600 feet above sea level. At first
glance, it seems an unlikely location, but the high-altitude, remote site is
perfect for astronomy.
The Observatory involves two
facilities. A 2.4-meter-diameter telescope began operations in 2008. It is “one
of the largest telescopes in the world that is used primarily to
study objects within our Solar System,” according to Director and
Astronomer Eileen Ryan in a 2010 interview. “These include asteroids, comets,
satellites (both naturally occurring and man-made), and planets. About seventy
percent of our current research efforts are directed toward
studying asteroids and comets that could impact the Earth sometime in
the future – these are called ‘potentially hazardous objects.’”
The scope can move up to 10 times
faster than a normal astronomical telescope, and has six ports to mount
instruments. A mirror can swing 360 degrees and switch to a different instrument
in under 30 seconds, giving it an unprecedented ability to track something
unexpected in the sky. They do research for the Air Force because, Lead
Maintenance Technician Craig Wallace-Keck said, “It’s one of the very few
existing telescopes of this caliber, this size, that has tracking capabilities
so we can monitor missile launches.”
The interferometer under construction |
10 Telescopes Combined
The second MRO facility, an array
of optical/infrared telescopes called an interferometer, is under construction.
This array will be similar to the Very Large
Array (VLA), a group of 27 radio antennas on the Plains of San Agustin in western New Mexico. However, the MROI
works in visible light and infrared wavelengths, while the VLA works in radio
waves. The interferometer will include 10 small telescopes, which can be placed
up to 340 meters apart. By combining the light from each of those, it acts like
a telescope 340 meters across and will make detailed images of astronomical
objects – about 100 to 300 times the resolution of the Hubble Space Telescope.
Other interferometers can get very
detailed images of small, bright things. Hubble can look at large, faint
things. The MRO interferometer can look at things smaller than the Hubble and
fainter than other interferometers can image. They’ll be able to see the
centers of galaxies and places where new stars are forming.
Scientists using the MROI will try
to better understand black holes, how planets are formed, and how stars form,
function, and die. Project Scientist Michelle Creech-Eakman noted that “Much of
what we know about stars, even our own star the Sun, is based on models and
theories that are sometimes more than one hundred years old.” Now scientists
are discovering planets around other stars and considering the possibility of
life elsewhere in the galaxy. The MROI will teach us more about stars and
planets, and ultimately our place in the universe. Like the 2.4-meter
telescope, the MROI can also help defend our planet and our country, by
studying asteroids in our solar system, and perhaps imaging satellites.
More research questions will arise
as scientists fully understand the capabilities of the MROI. Different groups
will rent the facility, helping pay operational costs. The community should
benefit in both jobs and tourism, including visiting scientists.
There’s a lot going on up on that
remote mountaintop. “Astronomy explores and tries to explain the universe
around us,” Director and Astronomer Eileen Ryan adds. “By studying the Solar
System we learn more about how the Earth formed, how it may change in the
future, and about what outside factors (i.e., asteroid impacts like the one
that killed the dinosaurs) can influence it. The MRO facility [also]
contributes positively to military interests that improve national security,
and it is active in educational enhancement within New Mexico.”
The average person may have a hard
time following the advanced science happening at MRO, but the magic of the
stars can touch us all. “We are all made of star dust,” Creech-Eakman says. “All
the material in our bodies was manufactured inside of a star.”
Hikers get a great view from the ridge |
Public tours aren’t available yet,
but visitors are welcome on the forest land around the MRO site. In order to
transport materials, the MRO team reconstructed forest road 235 from Water
Canyon to the ridge. The road is now kept open year-round with snow removal and
repairs, providing forest access to hunters and hikers.
The MRO also co-hosts an annual Enchanted Skies Star Party, which
includes a night of observing at the MRO site. This year’s event is October
14-17.
