We normally cover really big things in these pages, things like planets, stars and galaxies. But the cosmos is ultimately built from very small bits and pieces that organize themselves on a tiny scale that are at least as beautiful as anything to be seen in the night sky. This video, created by Beauty of Science, shows at an accelerated pace the formation of six kinds of crystals out of solution. Whereas many astronomical objects coalesce because of gravity, these crystals are made from a beautiful interplay of electric forces, geometry, and quantum mechanics. Quite a beautiful sight!Share This:

The planet Jupiter is always one of the brightest objects in the night sky. It’s brighter than any star, and is only outshone by the planet Venus and the Moon, and, very rarely, by Mars and Mercury. Jupiter reaches a position for optimum viewing in a telescope once every 13 months, roughly, and it makes its latest closest approach to Earth on June 10, 2019 when the planet appears in the (non zodiacal) constellation Ophiuchus along the southern ecliptic. A couple of months before and after this date, Jupiter is in perfect position for viewing with a small telescope, or even a pair of binoculars. You can’t miss it: the planet is by far the brightest object in the southeastern sky. The visible face of Jupiter reveals so many interesting features in a small telescope that the planet is a favorite target for new and experienced stargazers [Read more…] about A Guide to Observing the Planet Jupiter – 2019Share This:
In dark sky, northern-hemisphere observers can see the winter Milky Way as a featureless, inconspicuous band of haze running east of Orion and disappearing below the horizon south of the constellations Canis Major and Puppis. In light-polluted sky, the winter Milky Way is hard to see at all. But further south, into the far southern constellation Carina, the Milky Way suddenly explodes into one of its brightest, most spectacular, and most detailed sections, running through Crux, Centaurus, and beyond [Read more…] about Careening Through CarinaShare This:
The best way for an amateur astronomer to literally expand his or her horizons is to venture to the hemisphere opposite your home, to take in the starry wonders hidden from view by the pesky curvature of our globe. This is especially true for natives of the Northern Hemisphere, because the southern circumpolar sky offers some of the most spectacular sights available to any observer. Fine as the Big Dipper and the Double Cluster may be, they struggle to compete with the Magellanic Clouds and the southernmost parts of the Milky Way.
This is the philosophy that led to my three visits to New Zealand. I’m writing this from the Bay of Islands on the North Island, at 35o south latitude. I’ll share some of my observations in this inaugural edition of my observing column, Eyes on the Deep Sky. [Read more…] about Touring the Small Magellanic CloudShare This:
As the Moon reaches first quarter, and a day or two past, the Sun casts a dramatic shadow across the Mare Imbrium and a selection of prominent craters, mountains, and an unmistakable lunar valley. Even a tiny telescope will help you see these features as shown in the image above [Read more…] about Lunar Tour – Plato and RegionShare This:
