Water, Water, Everywhere? The cocoons of dusty, dark, molecule-rich gas clouds found in our own Milky Way galaxy and beyond are nurseries for new stars. Star formation in the Milky Way is slow and steady, but in other galaxies great bursts of star formation can and do occur. Read more...
ALMA Construction Construction of the network of antenna pads, as well as the roads, electrical cables and network cables tying them all to the Technical Building, has proceeded at the 16,400 foot elevation Array Operations Site (AOS). As each antenna pad receives its structural concrete, a curing process must follow, with the structure protected by a tent. Read more...
Carol Lonsdale Joins NRAO to Lead the North American ALMA Science Center We are pleased to announce the appointment of Carol Jean Lonsdale as the new NRAO Assistant Director for the North American ALMA Science Center (NAASC). As NAASC head, Carol will lead the team that will enable North American astronomers to effectively use the new observatory, support ALMA operations in Chile, and undertake research and development for future ALMA upgrades.

Expanded Very Large Array Status Significant progress on the WIDAR correlator has been one of the most exciting developments for the EVLA project over the summer of 2008. All 16 equipment racks for the correlator have been installed. The correlator boards that will be installed in the racks are connected to one another by a total of 500 high speed data cables, each capable of supporting data rates of about 10 Gbps. Read more...
The EVLA Vision: Galaxies through Cosmic Time The EVLA will have a continuum sensitivity 10 times the VLA, frequency coverage between 1 and 50 GHz that can be observed with an instantaneous bandwidth of up to 8 GHz, and at least 16 000 channels in each polarization. This vast increase in observing power brings unprecedented scientific capability to centimeter wavelengths that emplaces the EVLA as a world-leading radio telescope in the next decade. Read more...

Call for Proposals for NRAO Telescopes NRAO announces the Call for Proposals for trimester 09A. The call is open now and will close on October 1, 2008 at 17:00 EDT. Details of the call for the Green Bank Telescope (GBT) for observing from February 1, 2009 through May 31, 2009 can be found at http://www.gb.nrao.edu/gbtprops/latestgbtcfp.shtml. Read more...
Approved Joint Chandra/NRAO Proposals for Cycle 10 Recognizing that radio observations using the NRAO facilities will be important to the scientific exploration by the Chandra X-ray Observatory, up to 3% of the total observing time on each NRAO telescope was made available for joint observing. Chandra Cycle 10 observing will begin in 2008 December. Read more...
Approved Joint Fermi/NRAO Proposals for Cycle 1 Recognizing that radio observations using the NRAO facilities will be important to the scientific exploration by the Fermi Gamma-ray Space Telescope, up to 10% of the total observing time on each NRAO telescope was made available for joint observing. Fermi Cycle 1 observing began in 2008 August. Read more...
GUPPI Ready for Expert Users Beginning September 30, the new pulsar backend called GUPPI (Green Bank Ultimate Pulsar Processing Instrument) will be available for GBT pulsar observations in a shared-risk, expert user mode. GUPPI can be used for wide bandwidth (800 MHz) observations in conjunction with other existing pulsar instruments. Read more...
GBT K-band Focal Plane Array The 7-pixel K-band Focal Plane Array (KFPA) project reached a milestone on August 28, 2008 when the first complete pixel was installed in the test dewar and successfully cooled to 15 deg K. This array is the first in a planned series of new multi-pixel heterodyne instruments for the GBT. Read more...
Observing with the VLA-EVLA Transition Array There are now 17 EVLA antennas in the array, and though the amount and severity of the teething problems we encountered initially have decreased substantially, we continue to urge all observers to carefully read the EVLA returns page prior to observing and/or data reduction. Read more...
VLBA Sensitivity Upgrade The Digital Backend (DBE) sub-band processor module, the first element of the upgraded 4-Gbps data path, passed a major milestone with the satisfactory evaluation of the second prototype ROACH (formerly "iBOB-2") board. Limited production of copies of this board has begun for partners in the development collaboration, including the NRAO, the South African KAT project, and the UC-Berkeley CASPER Laboratory. Read more...
VLBA Recording Media It has been well over a year since we expanded the VLBA's Mark 5 recording media pool. The primary limitation has been problems in support of the newer, serial-ATA (SATA) interface rapidly being adopted by the disk-drive industry. Read more...
NRAO Lab Notebook A great deal of technical development work directly relevant to the Square Kilometer Array (SKA) and the future of existing radio telescopes is taking place in NRAO computing and electronics laboratories. Sometimes, this work goes unnoticed in the international arena of discussion of large future telescopes. Read more...
The 2008 NRAO Summer Student Program August brought to a close the 49th year of the NRAO Summer Student program. Twenty-three students participated in 2008 NRAO Summer Student program, including 16 undergraduate students supported by the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) program, three graduating seniors supported by the NRAO Undergraduate Summer Student program , and four graduate students supported by the NRAO Graduate Summer Student program.

Governor is Inspired by Governor's School Students Mid-August marked the passage of the 4th annual West Virginia Governor’s School for Math and Science (GSMS) in Green Bank—a two-week residential program for 60 talented 14-year olds from around the state. In a nutshell, GSMS focuses on instilling a strong appreciation for mathematics and the sciences while students are in middle school, before they make critical decisions that will guide their academic and professional careers.
