On August 17, 2017, scientists made history with the first direct observation of a merger between two neutron stars. It was the first cosmic event detected in both gravitational waves and the entire spectrum of light, from gamma rays to radio emissions. The impact also created a kilonova -- a turbocharged explosion that instantly forged several hundred planets’ worth of gold and platinum. The observations provided the first compelling evidence that kilonovae produce large quantities of heavy metals, a finding long predicted by theory. Astronomers suspect that all of the gold and platinum on Earth formed as a result of ancient kilonovae created during neutron star collisions. Based on data from the 2017 event, first spotted by the Laser Interferometer Gravitational-wave Observatory (LIGO), astronomers began to adjust their assumptions of how a kilonova should appear to Earth-bound observers. A team of scientists reexamined data from a gamma-ray burst spotted in August 2016 and found new evidence for a kilonova that went unnoticed during the initial observations.

While scientists have made remarkable advancements in astronomy and astrophysics since the beginning of this decade – notably the first detection of gravitational waves and the discovery of distant Earth-like planets – unforeseen constraints have slowed progress toward reaching some of the priorities and goals outlined in the Academies’ 2010 decadal survey of these disciplines, says a new report from the National Academies of Sciences, Engineering, and Medicine.

To advance the search for life in the universe, NASA should support research on a broader range of biosignatures and environments, and incorporate the field of astrobiology into all stages of future exploratory missions, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.

As NASA prepares to send astronauts to the moon and Mars, it is revisiting the latest research on cancer risk from space radiation. A new report recommends NASA proceed with setting a new radiation exposure limit, and improve how it communicates cancer risk to astronauts.

A new decadal survey presents a visionary plan for the fields of astronomy and astrophysics, identifying scientific priorities and opportunities, and recommending an ambitious program of investment to strengthen the profession and achieve new capabilities.

How do you solve the world's toughest problems? Or find the next big thing in tech? Lots of organizations fail to explore and take big bets on new ideas because they can't tolerate the mess of experimentation and the fear of failure. At X, Alphabet's dedicated innovation factory, they don't have that problem, and Astro Teller, Captain of Moonshots at X, can explain why. Undertaking projects on everything from rural communication to ocean health to machine learning, he and his teams operate with different creative mindsets and decision-making principles than many of us. He spoke with host Alison Beard at HBR at 100: Future of Business live virtual conference.

It's hard to imagine a more challenging work environment than the International Space Station. During her 24 years as a NASA astronaut, including a six-month stint on the ISS, Cady Coleman learned pivotal lessons about everything from managing stress and assessing risk to cross-cultural communication and navigating bias. She shares how the skills she picked up can be applied in all kinds of careers. Coleman is the author of the book Sharing Space: An Astronaut's Guide to Mission Wonder and Making Change.
