Almost every star is now thought to form with a planetary system around it. But just how rare a phenomenon are habitable planets? In this podcast, Massachusetts Institute of Technology professor Linda Elkins-Tanton discusses what is currently known about planetary formation—and what is needed to encourage the development of life.
Dr. Elkins-Tanton’s talk, “A Hitchhiker’s Guide to Habitable Planets in Our Galaxy,” was recorded at the Museum on April 11, 2011.

Blogging from Lowell Observatory in Flagstaff, Arizona, Emily Rice, a research scientist in the Museum’s Department of Astrophysics, is working with a collaborator to model the atmospheres of low-mass stars, brown dwarfs, and giant gas planets, including descriptions of their chemistry and clouds. A major new exhibition about the future of space exploration opens at the Museum this fall.
For this trip, I made an unfamiliar journey to a familiar destination: Lowell Observatory in Flagstaff, Arizona. I have visited Lowell almost 10 times in the past seven years, but until this trip I was traveling to Flagstaff from Los Angeles, where I was studying astronomy at University of California, Los Angeles. For this, my first trip to Lowell since becoming a research scientist at the Museum, I spent 14 hours taking three flights from bustling New York City to tranquil Flagstaff.

Blogging from the Kitt Peak National Observatory in the Sonoran desert in Arizona, Jackie Faherty, a research scientist in the Museum’s Department of Astrophysics, is on an observing trip this month to study brown dwarfs and low-mass stars that are potential hosts to exoplanets. A major new exhibition about the future of space exploration opens at the Museum this fall.
One of the rituals that I follow without fail at a telescope is watching the sunset and sunrise. It is an essential part of any observing run and a wonderful marker of how our work night begins and ends. Night five at Kitt Peak provided a spectacular sunset, with perfect pink and red puffy clouds on the horizon. This is actually terrible for observing as the pesky clouds interfere with collecting data from way out in the cosmos. Luckily, a few hours into the evening the majority of weather blew off, and I was able to take high-quality data.

Astronomers associated with NASA’s Kepler observatory have announced the discovery of more than 1,200 new candidate exoplanets. Michael Shara, a curator in the Museum’s Department of Astrophysics, writes about the significance of the findings below.
Does life exist anywhere in the universe except on Earth? “Star Trek” may have convinced much of the public that the universe is teeming with technological civilizations, but the correct answer is: We don’t know for certain if life–even bacterial life — exists anywhere except on Earth. A critical challenge in answering this question is determining whether planets — especially Earth-like planets — orbit other stars.
The search for Earth-like planets has just taken a giant leap forward, thanks in part to the tireless work of the dozens of astronomers associated with NASA’s Kepler observatory. Their quest to find exoplanets — planets orbiting stars other than our Sun — has been a stunning success. It is now certain that planets are as common stars.
Fifteen years ago the University of California, Berkeley’s Geoff Marcy and a handful of colleagues began an almost quixotic quest for exoplanets. Dozens, and then hundreds of astronomers joined the quest after Geneva’s Michel Mayor, Marcy, and their colleagues began reporting the first discoveries. Herculean efforts led to the cataloguing of 500 exoplanets by the end of 2010. Now the Kepler team has announced the discovery of more than 1,200 new candidate exoplanets, and enough details about each of these new worlds to begin to draw far-reaching conclusions about abodes for life in the universe.
