History of [#eclipses (3/3)] From now on, there's no need to wait for the next total #Sun#eclipse and to travel the globe to observe it: the development, on the ground and in space, of #coronography - a technique invented in 1931 by Bernard Lyot - makes it possible to reproduce this celestial phenomenon.
Histoire [#éclipses (2/3)] Ce lundi, une éclipse totale de #Soleil se produira au-dessus du continent nord-américain. La #couronne solaire sera alors visible à l'oeil nu et devrait ressembler à l'image ci-dessous, d'après les chercheurs du Predictive Science Inc.
Ces derniers ont conçu un #modèle 3D de la couronne solaire basé sur diverses données d'observation, au sol et dans l'espace - issues notamment de la sonde #SolarOrbiter de l'ESA.
How the ancient art of eclipse prediction became an exact science - The timing of the total eclipse on April 8, 2024, will be known to within a second, thousands of years after fearful humans first started trying to anticipate these cosmic events. #SolarEclipse#Eclipse#Eclipses
"Wondering how much of the eclipse you will see? NASA has a tool that lets you search by city or ZIP code to see complete eclipse details. For example, in Huntsville, the eclipse will start at 12:42 p.m. and be completely finished by 3:18 p.m. At its maximum, 90% of the sun will be covered by the moon."
A team of researchers from Strasbourg ´s Observatory has selected 41 bright astrometric binaries from the 3rd Gaia data release (#Gaia-DR3) that could also be eclipsing #binaries and double-line spectroscopic binaries (SB2).
Photometric observations from amateur astronomers to cover #eclipses effectively are needed.
