Some of us who traveled 4 hours or 4 days to expertise totatlity through the current photo voltaic eclipse have been disenchanted when their viewing expertise was disrupted by cloud cowl. However a few of these eclipse chasers noticed one thing these below clear skies didn’t get to see. As totality approached, the shadow of the moon raced alongside the clouds at 1000 miles per hour, swallowing air and land and sea. Fairly wonderful, for a cloud-obscured celestial occasion. And for more information on lunar shadows, right here’s an amazing lowdown from Astronomy Now:
More and more taking cost of the night sky, [the moon] turns into extra apparent towards a darkening backdrop as its part advances in the direction of first quarter. Afterwards circling additional behind our planet, it makes its look ever later into the night time as daylight steadily consumes the Earth-facing floor till the utmost illumination of full Moon.
Within the 14 or so days between new and full, the shadowed line between mild and darkish that we name the terminator passes by way of a number of the Moon’smost fascinating options – some well-trammelled, others much less so. I wish to take you on that journey, sampling just some of these treats, wanting by way of three visible home windows: with the attention alone, by way of binoculars (by which I imply the ‘classical’ 7× to 10 × 50mm class) and with the help of a small telescope of perhaps 70- 80mm (~three-inch) aperture.
