AMATEUR RADIO ASTRONOMY • 21-CM NEUTRAL HYDROGEN
Deep Space
1420 MHz
Radio Telescope
A 4.5-meter radio telescope built for long-term 1420 MHz radio astronomy, repeated observations of the Milky Way, and open sharing of the resulting data and visualizations.
CURRENT OBSERVATORY STATUS
Live sky, solar and local conditions
Current conditions for the observatory.
Weather: National Weather Service • Solar flux: NOAA SWPC • Sun/Moon positions and phase: calculated in-browser for the observatory location.
LONG-TERM AMATEUR RADIO ASTRONOMY
Observe. Repeat. Compare. Share.
Use the dedicated tabs above for the telescope hardware, observation results, workflow, paper and data archive.
LIVE OBSERVATORY
Current telescope livestream
This panel follows the current live broadcast from the Deep Space 1420 YouTube channel rather than a permanently fixed video.
THE OBSERVATORY
A purpose-built 4.5-meter radio telescope
This tab is only about the telescope, receiver chain, positioning system and control station.
CONTROL & INSTRUMENTATION
Observation and processing station
The control station handles telescope positioning, receiver monitoring, recording and the software tools used to operate the observatory.
REAL OBSERVATION PRODUCTS
Measured data — no simulated display graphics
Featured continuum, spectral and 3D observation results.
OBSERVATION WORKFLOW
From the sky to a finished radio-astronomy product
The workflow shows how a telescope pointing becomes recorded data, processed measurements and final plots or three-dimensional visualizations.
OBSERVATORY LOG
