The Great ‘South American Eclipse’ of 2019

July 2, 2019 by Brian Ventrudo Filed Under: Celestial Events


Observers in a narrow band across the southern Pacific Ocean and north-central Chile and Argentina enjoyed a rare spectacle today: a total solar eclipse. The lovely seaside towns of La Serena and Coquimbo, Chile, enjoyed two minutes and thirteen seconds of totality, and observers at some of the world’s great astronomical observatories got in on the fun. This is the first total solar eclipse visible anywhere since the ‘Great American Eclipse‘ of August 21, 2017. The next total solar eclipse occurs on December 14, 2020, once again across the South Pacific, Chile, and Argentina.

The Poet Laureate of Stargazing

May 31, 2019 by Brian Ventrudo Filed Under: Stargazing


Today marks the 200th anniversary of the birth of the great and good American poet, essayist, and humanist Walt Whitman. Sometimes called the ‘father of free verse’, Whitman was often beheld as the key to understanding America as it was in the promising days of late 19th century, after the Civil War. He was also, in my view, the poet laureate of stargazers everywhere, especially on account of two of his poems ‘When I Heard the Learn’d Astronomer’ and ‘A Clear Midnight’, reproduced below for your reading pleasure.

“A Clear Midnight”
This is thy hour O Soul, thy free flight into the wordless,
Away from books, away from art, the day erased, the lesson done,
Thee fully forth emerging, silent, gazing, pondering the themes
thou lovest best,
Night, sleep, death and the stars.

“When I Heard the Learn’d Astronomer”
When I heard the learn’d astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time,
Look’d up in perfect silence at the stars.

Or enjoy the latter poem in the video format below (which is likely the only time you will ever see a video from ‘Breaking Bad’ on this website):

Emergent Crystals

May 9, 2019 by Brian Ventrudo Filed Under: Science

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!

Lunar Tour – Plato and Region

March 20, 2019 by Brian Ventrudo Filed Under: Solar System

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 Region

The Star of Good Fortune, and Old Age

February 14, 2019 by Brian Ventrudo Filed Under: Deep Sky

The star Canopus, low in the sky and left of center in this image, lies well below the constellation Orion, at top center, and Canis Major (at upper left). As seen from the Winter Star Party, near Summerland Key, Florida, in 2017.

Canopus is located in the southern constellation Carina, the Keel, and it is by far the brightest star in the constellation. At a declination of about -52o, Canopus never rises above the horizon for observers north of 38oN latitude. Many northerners catch sight of it while travelling south for winter vacation.  Almost directly south of Sirius, Canopus is just visible in the months of northern winter from southern Spain and Portugal, and from the southern United States. In the southern hemisphere, these two brightest stars are directly overhead in the evening summer sky [Read more…] about The Star of Good Fortune, and Old Age
