Europe has approved the construction of the European Extremely Large Telescope (E-ELT), which when completed will be the largest ground-based telescope.
The E-ELT will have a mirror 39 meters across, almost four times bigger than the world’s largest telescope today.
A word to the wise: This very month Sky & Telescope’s cover article, written by yours truly, describes the many difficulties the world’s present generation of giant telescopes have faced. Four out of five have not produced the science promised. Two of the four were dogged by so many technical problems that they required complete reconstruction. The builders of E-ELT will face even greater engineering challenges. Do not be surprised if this telescope does not get completed by 2025 as promised, and even if it does, do not be surprised if it takes another half decade or more before the engineers work out all the kinks.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space
, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
