What it is : Radio figure of an annularsolar occultation .
When it was taken : Oct. 14 , 2023 .
Radio images of October’s annular solar eclipse as seen by the Long Wavelength Array, with images below of what it looked like in visible light.
Where it was contain from : Owens Valley Radio Observatory Long Wavelength Array ( OVRO - LWA ) , California .
Why it ’s so special : Scientists have learn the first receiving set scope picture of an annular solar eclipse ’s famous " ring of fire " effect — even though they were outside the eclipse ’s cardinal path .
On Saturday , Oct. 14 , 2023,an circinate solar eclipsewas seeable from inside a 125 - mile - all-embracing belt through nine U.S. state , include the northeasterly tip of California . Owens Valley Radio Observatory , in Big Pine , California , was not within that course , so it was only able to image an 80.5 % fond solar eclipse , according tothis Interactive Google Mapfrom French occultation map maker Xavier Jubier . ( Within the path of the eclipse , as much as 91 % of the Lord’s Day ’s Inner Light was blocked ) .

However , radio astronomer were still able to appropriate radio prototype of the " ring of fervidness " because OVRO - LWA detect the sunlight ’s corona , or super - hot out atmosphere , which was inconspicuous to those watching the solar eclipse .
" From our lookout station site in California we were not in the belt to see the annular eclipse , yet we ’ve been able to ' see ' it all clearly unfold in radio , which reveals a much larger solar disk than its seeable counterpart thanks to its sensitivity to the extended solar corona,“Bin Chen , associate professor of physics at New Jersey Institute of Technology ’s Center for Solar - Terrestrial Research ( NJIT - CSTR ) who led the observations with colleagues , said in astatement .
tuner astronomy is the survey of supernal object atradio frequencies , which are invisible to human eyes . OVRO - LWA ’s nearness to the way provide a unequaled opportunity to examine the sun ’s extended corona with the raiment ’s 352 antennas , taste thousands of radio wavelengths at once .

" To in the end see a ' pack of fire ' occultation this way was spectacular … we have n’t seen this quality of radiocommunication imaging of the sun before,“Dale Gary , a prof of physics at NJIT - CSTR and co - investigator on the OVRO - LWA task , articulate in the assertion . " We commonly can not see the electric glow from the ground except during a total occultation , but we can now see it all the time with OVRO - LWA . This occultation makes it that much more dramatic . "
The circinate solar eclipse on Oct. 14 also traverse parts of Mexico , Belize , Honduras , Nicaragua , Panama , Colombia and Brazil . The nextsolar eclipsevisible from North America will be a total one , crossing from the southwest to the northeast on April 8 , 2024 .
