They noticed two starlike objects where their radio observations indicated there should be only one.

In the 1950s and 1960s he made discoveries based on radio observations of the Sun.

This size measurement corresponded well with indirect estimates using infrared emission and radio observations.

With more detailed radio observations, the morphology turns out to reflect the method of energy transport in the radio source.

It has also contributed to radio observation for the SETI project.

The theory that Mercury's rotation was synchronous had become widely held, and it was a surprise to astronomers when these radio observations were announced.

Tempo is a computer program to analyze radio observations of pulsars.

Before radio observations in the 1960s, many believed that Venus contained a lush, Earth-like environment.

By comparing the timing of these pulses with high-resolution radio observations, the authors were able to match them to a single source, named J1823 3021A.

With this technique radio observations couple the phase information of the radio signal observed in telescopes separated over large distances.
