The little-known true story of the unexpected and remarkable contributions to astronomy made by a group of women working in the Harvard College Observatory from the late 1800s through the mid-1900s. -- Provided by publisher. "In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or "human computers," to interpret the observations their male counterparts made via telescope each night. At the outset this...

An astrophysicist presents an in-depth yet accessible tour of the universe for lay readers, while conveying the excitement of astronomy-- Provided by publisher.

"We have the impression that the solar system is perfectly regular like a clock, or a planetarium instrument. On a short timescale it is. But, seen in a longer perspective, the planets, and their satellites, have exciting lives, full of events - for example, did you know that Saturn's moon, Titan, boasts lakes which contain liquid methane surrounded by soaring hills and valleys, exactly as the earth did before life evolved on our fragile planet? Or...

Black holes are one of the greatest mysteries of outer space. No visible light can escape the strong gravity of a black hole. This makes black holes invisible-and very difficult to study. But scientists make new discoveries and develop new theories about these mysterious objects every day. In 2015, astronomers were able to finally confirm a theory that Einstein had developed one hundred years earlier! And in 2016, scientists found that black holes...

"This title shows how a group of European scientists, in the span of roughly one hundred and fifty years (early 1500s to the mid-1600s) and working through direct observation, overturned the centuries' old accepted view of a geocentric universe. Through their research and writings, they proposed and described a new order of things in which the Earth orbits the Sun. In so doing, these scientists--Nicolaus Copernicus, Johannes Kepler, Tycho Brahe, Galileo...

"From the acclaimed author of Black Hole Blues and Other Songs from Outer Space--an authoritative, wholly accessible, fascinating guide to the most challenging phenomena of contemporary science, which is now the anchor of our understanding of the cosmos. Throughout her career, astrophysicist Janna Levin has focused, alongside her research, on making the science she studies not just accessible, but, perhaps more important, intriguing to the nonscientist....
