Long Ago

Long ago,
when a boy,
my grandfather,
had his own toy.
A device, with a wheel,
which looked like a tricycle.
It had a seat and pedals,
like a bicycle.
You pumped the pedals,
but never went anywhere,
for the wheel was stone.
It was used to sharpen
tools, and give knives a hone.
A small container of water,
hanging above the wheel,
dripped on the stone and
provided a fine edge to
the knives with this
very large whetstone.
Ah, memories, so important
to whom we are today.

NASA Astronomy Picture of the Day:

How many galaxies are interacting here? This grouping of galaxies is called the Wild Triplet, not only for the discoverer, but for the number of bright galaxies that appear. It had been assumed that all three galaxies, collectively cataloged as Arp 248, are interacting, but more recent investigations reveal that only the brightest two galaxies are sparring gravitationally: the big galaxies at the top and bottom. The spiral galaxy in the middle of the featured image by the Hubble Space Telescope is actually far in the distance, as is the galaxy just below it and all of the other numerous galaxies in the field. A striking result of these giants jousting is a tremendous bridge of stars, gas, and dust that stretches between them -- a bridge almost 200,000 light-years long. Light we see today from Wild's Triplet left about 200 million years ago, when dinosaurs roamed the Earth. In perhaps a billion years or so, the two interacting galaxies will merge to form a single large spiral galaxy.

NASA Astronomy Picture of the Day:

If the full Moon suddenly faded, what would you see? The answer was recorded in a dramatic time lapse video taken during the total lunar eclipse in 2011 from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically. The Moon never gets completely dark, though, since the Earth's atmosphere refracts some light. As the featured video begins, the scene may appear to be daytime and sunlit, but actually it is a nighttime and lit by the glow of the full Moon. As the Moon becomes eclipsed and fades, background stars become visible and here can be seen reflected in a lake. Most spectacularly, the sky surrounding the eclipsed moon suddenly appears to be full of stars and highlighted by the busy plane of our Milky Way Galaxy. The sequence repeats with a closer view, and the final image shows the placement of the eclipsed Moon near the Eagle, Swan, Trifid, and Lagoon nebulas. Nearly two hours after the eclipse started, the moon emerged from the Earth's shadow and its bright full glare again dominated the sky. Later today or tomorrow, depending on your location relative to the International Date Line, a new total lunar eclipse will take place -- with totality being primarily visible over northeastern Asia and northwestern North America. Total Lunar Eclipse of November 2022: What you need to know.
