The Lost Planets

The Lost Planets

A fascinating account of the pioneering astronomer who claimed (erroneously) to have discovered a planet outside the solar system.There are innumerable planets revolving around innumerable stars across our galaxy. Between 2009 and 2018, NASA's Kepler space telescope discovered thousands of them. But exoplanets-planets outside the solar system-appeared in science fiction before they appeared in telescopes. Astronomers in the early decades of the twentieth century spent entire careers searching for planets in other stellar systems. In The Lost Planets, John Wenz offers an account of the pioneering astronomer Peter van de Kamp, who was one of the first to claim discovery of exoplanets. Van de Kamp, working at Swarthmore College's observatory, announced in 1963 that he had identified a planet around Barnard's Star, the second-closest star system to the Sun. He cited the deviations in Barnard's star's path-"wobbles" that suggested a large object was lurching around the star. Van de Kamp became something of a celebrity (appearing on a television show with "Mr. Wizard," Don Henry), but subsequent research did not support his claims. Wenz describes van de Kamp's stubborn refusal to accept that he was wrong, discusses the evidence found by other researchers, and explains recent advances in exoplanet detection, including transit, radial velocity, direct imaging, and microlensing. Van de Kamp retired from Swarthmore in 1972, and died in 1995 at 93. In 2009, Swarthmore named its new observatory the Peter van de Kamp Observatory. In the 1990s, astronomers discovered and confirmed the first planet outside our solar system. In 2018, an exoplanet was detected around Barnard's Star-not, however, the one van de Kamp thought he had discovered in 1963.

James Turrell

James Turrell

To encounter a work by American artist James Turrell is to enter another world--a realm where eye and mind meet. The artist engages us, the viewers, in order to make us witnesses of his focus on nature through scientific means. By making us watch and contemplate for extended periods, Turrell also makes us part of his artistic practice. Turrell is unusual among contemporary artists in that his environments construct spaces, leaving their workings largely unseen. Skyspaces , outside or inside, veil their lighting so that only its effects, and not its cause, are visible. The areas that audiences enter, singly or in groups, are built so that viewers are liberated from normal perceptions. Perceptual cell , for instance, may remind us initially of medical imaging for diagnosis, but instead of closing down our senses, it opens them to new experiences.Turrell strives to go beyond the conventional by naturalizing technology for aesthetic purposes, allowing his grasp of science to suggest the ineffable. As well as showing the variety of his means, such as bright color and white light, neon, LED and other forms of light, and individual and communal encounters inside and out, the exhibition underlines the unique vision that has led him through the last decades in pursuit of light, space and time. This publication includes an interview with James Turrell by Michael Govan, director of the Los Angeles County Museum of Art, and an essay by EC Krupp, astronomer and Director of the Griffin Observatory, Los Angeles.

Secrets of the Universe

Secrets of the Universe

In an age of unprecedented astronomical discovery, world-renowned astronomer Paul Murdin tells the stories of the men and women who first revealed the shape of the Earth, the existence of Pluto, the principles of relativity and cosmic marvels such as black holes and interstellar nebulae. Their findings revolutionized our view of the Universe, our planet, the stars that shine in the night sky and the vastness of space beyond it. Murdin explains clearly the science behind these great discoveries, along with the passions, struggles and quirks of fate that made for some of the most intriguing human dramas of their times. With more than 500 stunning illustrations from historic prints and paintings to the latest satellite photography, and including specially commissioned artworks, the discoveries described demonstrate how ingenuity, technological innovation and occasionally pure serendipity have expanded our knowledge of the Universe beyond anything we could ever have imagined.
