A grid of 9 images of starburst galaxy NGC 253 with different colors representing different molecular species. In order: molecular gas (blue), shocked regions (red), relatively high-density regions (orange), young starbursts (yellow), developed starbursts (magenta), and molecular gas affected by cosmic-ray ionization (cyan).

Science image of starburst galaxy NGC 253, as observed by ALMA. A red region represents the lower density carbon monoxide (CO) gas surrounding higher density star-forming regions (stellar nurseries) in yellow.

Using #ALMA Observatory, astronomers studied what makes the gas in these places so much more efficient at star formation. The researchers identified 10 distinct stellar nurseries within the heart of NGC 253 and mapped the distribution of about 40 different molecular species.

NSF NRAO devoted 340 hours of VLA observing time to system tests and reception of Voyager's telemetry, and there were 40 scheduled telemetry passes from 26 April through 28 September 1989.

NSF NRAO began planning and preparations in 1982; phased-array observing tests on Voyager and planets began several years before the encounter as more antennas became outfitted for X-band.

#ThrowbackThursday Did you know that the Very Large Array helped with NASA’s Voyager 2 mission? 🛰️

The VLA was used with Jet Propulsion Laboratory’s Deep Space Network in Goldstone CA to track NASA’s Voyager 2 encounter with Neptune in 1989.
