However, the new observations of the radio Sun’s eclipse — much longer in duration than the partial eclipse recently experienced by millions on Earth due to the extended solar corona as seen at radio wavelengths — have yielded stunning images of the eclipse’s ring lasting for over an hour.
“We normally cannot see the corona from the ground except during a total eclipse, but we can now see it all the time with OVRO-LWA. This eclipse makes it that much more dramatic.” For solar science, it offers the highest-quality images yet of the radio Sun in this wavelength regime, which is roughly two times larger than the visible solar disk.

In 1952, a group of three 'stars' vanished—astronomers still can't find themOn July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photographic plate captured the light of three stars clustered together.
