24h x 60 min = 1440 mins/day = 86400 sec 360° / 86400 = 0.0041° per second 72 seconds = 0.3° An arcminute (denoted by the symbol '), is an angular measurement equal to 1/60 of a degree or 60 arcseconds. To convert a degree measurement to a minute of arc measurement, multiply the angle by the conversion ratio. The angle in minutes of arc is equal to the ...

This is answering a somewhat different question, but one that seems implied by this one: To put a radio telescope on Mars requires the capability to launch the radio telescope to Mars, and then to land it on Mars and then deploy it there. This will be considerably more costly and difficult than just launching it into solar orbit...after all, the first step ...

Is it possible to detect signal from SII, Hα, OIII using radio telescope and make the similar images as optic telescope? If no, can we use the different elements to take signal? Radio telescopes, quite sensibly, observe in the radio band (or more usually the microwave band). All the emission signals you mentioned are in the optical band. SII is $671.6\:\...

The following table is based on The measurement of large antennas with cosmic radio sources (sorry for the paywall), Table I "Radio Sources for Antenna Measurements", Panel A "Flux Density and Polarization Data". This table contains some of the brightest "point sources" at microwave frequencies. I have extracted only the flux ...

This is an answer that I am writing up based on comments by ProfRob and Mike G. The meaning of 'beta' in these plots is the slope of the line. The figure itself is from Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation (arXiv link). From the caption of the figure in the ...

The Sun emits incoherent radio signals over the full range of frequencies. The signals are not modulated in any meaningful way. Humanity emits signals at particular frequencies that are then modulated in various ways to contain information. It is the careful analysis of signals in narrow frequency bands that enables you to sort out the signal from the noise. ...
