Venus Bubbles


This is pretty cool – do a little space homework, find out when the Moon or planets appear in the direction of setting Sun. Take a piece of picture frame size glass outside at sunset. Find an appropriate place to fasten it between yourself and the setting sun. Sprinkle glass with drops of water. Focus your camera lens on the drops of water…….

Photographer John Bell of Haversham, Bucks, UK followed the recipe and obtained the picture above on Jan. 17, 2017.

“I had been looking at macro photos of flowers through droplets and thought I’d try the same with the evening sky,” explains Bell. “I taped a photoframe glass to a tree branch in my garden and framed the droplets using my Canon 5D MK2 with a sigma 106mm macro lens. The view was of Venus by a neighbour’s tree.”

Water droplets act as inverting lenses, so in the original photo the sunset was upside down. “Easily fixed,” says Bell, who restored order by rotating the image 180 degrees. “Focusing was a bit difficult,” he adds. “After all, water droplets are not perfect lenses.” The result, however, was perfectly beautiful.

MLK Day


First posted 4 years ago, I do so again because nothing has changed. Donald Trump blithers “Make America great again” without an inkling of what a great nation stood for. MLK knew what it meant. He knew racial inequality choked the premise America might ever be great.

Today, January 18, 2016 is Martin Luther King Day in America. A federal holiday falling on the Monday closest to January 15, the day MLK was born in 1929. MLK was assassinated in Memphis, Tennessee on April 4, 1968. Establishing MLK Day wasn’t easy – a 1979 vote by the House of Representatives –  defeated by 5 votes. In 1980/81, six million signatures supporting MLK Day were collected on a petition to Congress – deemed “the largest petition in favor of an issue in U.S. history”. Republican Senators Jesse Helms and John Porter East from North Carolina led the opposition. Helms orchestrated a filibuster against the bill in 1983, producing a 300 page document alleging King associated with communists. New York Senator Patrick Moynihan threw it on the Senate floor, declaring it a “packet of filth” as he stomped on it. On November 2, 1983 president Ronald Reagan set aside…

Titan Touchdown


On January 11, 2017 NASA’s Jet Propulsion Laboratory ( JPL ) released “Titan Touchdown”, a short video of stoic little probe Huygens landing on Saturn’s moon Titan. A video marking the 12th anniversary of January 14, 2005, the day Huygens bravely marched into history as the furthest ever landing from Earth. The day Huygens met fate in a blaze of glory, making the most of precious minutes until Titan claimed it for eternity.

The Cassini-Huygens mission holds a place in my heart – RIP Huygens, your sacrifice won’t be forgotten.

Have You Seen The Milky Way?


Born under starry skies, rural seclusion wrapped childhood in the Milky Way. Constant, permanent, watchful – I left for city lights without saying goodbye. We still see each other every few years, picking up where we left off like old friends do. When time comes to part I wave goodbye, mindful of cosmic wonders that shaped my life. Pondering the fact 80% of people alive today have never seen the Milky Way.

Draugr, Poltergeist and Phobetor


January 9, 2017 marks the 25th anniversary of Exoplanet discovery. On this day in 1992 the science journal Nature published a paper by astronomers Alex Wolszczan and Dale Frail detailing first confirmation of planets orbiting a star beyond our solar system. That star was a pulsar, 2300 light years away in the constellation Virgo, known as PSR B127+12. Pulsars are maelstroms of fast spinning highly magnetized solar remnants created when mass at the moment of supernova isn’t enough to make a black hole. Instead the outer layer blasts to oblivion, leaving an inner core of dense material exerting unimaginable gravitational force. Spinning countless times per second, those maintaining angular momentum become pulsars – distinguished by intense beams of radio emissions several times a second, similar to a lighthouse beacon.

At Arecibo Observatory in Puerto Rico Frail and Wolszczan witnessed regular dimming of the pulsar beacon, split second interruptions caused by orbiting planets. Two planets, PSR1257+12b (orbiting once every 66 days) and PSR1257+12c (one orbit every 98 days) became our first proven exoplanets. In 1994 they discovered PSR1257+12d, a tiny third exoplanet orbiting once every 25 days.

In 2015 the International Astronomical Union sponsored a Name Exoworlds contest, 12b, c and d became Draugr, Poltergeist and Phobetor. In 2009 NASA launched the Kepler Space Telescope using the same method of light interruption to detect planetary orbits. To date Kepler has identified 2330 of the over 3500 confirmed exoplanets. Happy exoplanet anniversary,
