On approach to Saturn, data obtained by the Cassini spacecraft are already posing a puzzling question: How long is the day on Saturn? Credit: NASA, the European Space Agency and the Italian Space Agency
Inside the fossilized bones of Archaeopteryx, one of the earliest bird-like dinosaur specimens, researchers have found evidence of a capability for flight.

UPDATE (20 Aug 2015): What made the comet sing? Scientists working on Rosetta's RPC instrument have found out why 67P/C-G was singing. Via http://wp.me/p46DHN-1nN == ORIGINAL Citation (Oct 2014): Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased in this recording. This sonification of the RPC-Mag data was compiled by German composer Manuel Senfft (www.tagirijus.de).

Before settling into orbit around Saturn, Cassini faced a white-knuckle ride through the plane of the planet’s rings. When converted into an audio file, the interstellar cacophony is reminiscent of a hellstorm on Earth.
This is a sound that was electronically placed onboard the Voyager 1 and 2 spacecraft.
These melodious tones are created at a special frequency in a plasma with a magnetic field. The frequency is set by the number of electrons in a given volume (the electron density) and the strength of the magnetic field. Hence, the frequency of these waves, called upper hybrid waves, can provide a very accurate measure of the density of the plasma; a fundamental property of the Jovian environment of interest to scientists. These emissions were acquired by Voyager 2 as it passed through the outer magnetosphere in 1979.
This is a greeting to the universe that was electronically placed on the Voyager 1 and 2 spacecraft. English Translation: "Hello everybody."
A gentle rainshower refreshes the air of the forest. Raindrops patter on the forest floor and drip from every gleaming leaf and fern. After the rain, the forest is cleansed and birdsong returns.
Our Halloween special investigates the science of ghosts and other haunting phenomena.
This is a greeting to the universe that was electronically placed on the Voyager 1 and 2 spacecraft. English Translation: "To all those who exist in the universe, greetings."
A conversation with and Marianne Sowa, branch chief of the Space Biosciences Research branch at NASA's Ames Research Center in Silicon Valley, and Jack Miller, Lawrence Berkeley Laboratory, about radiation science using GeneLab.

SERIES PREMIERE SPECIAL EDITION: This special edition of the series premier of our new podcast, Playing with Science, features additional content by Neil deGrasse Tyson before and after the show. In between, hosts Gary O’Reilly & Chuck Nice huddle up for Sunday’s big game with Super Bowl champs Osi Umenyiora (NY Giants) & Santonio Holmes (Pittsburgh Steelers), astrophysicists Charles Liu & Neil deGrasse Tyson, & comic James L. Mattern.

We start our “Gravity Assist” virtual tour of the solar system with – where else – the Sun! How hot is the Sun, what are solar flares, and how does space weather affect us here in Earth? Jim is joined by Project Scientist Dr. Nicky Fox of the Johns Hopkins University Applied Physics Lab to talk about our fascinating star and NASA’s upcoming Parker Solar Probe—a mission to “touch the Sun.”
More people in the U.S. died from opioids in 2016 than the peak year of the AIDS epidemic. So how did we get here? We speak to Prof. June Dahl, pain specialist Dr. David Tauben, and emergency physician Dr. Jeanmarie Perrone. If you or someone you love is struggling with an opioid addiction, in the US you can call the Substance Abuse and Mental Health Services Administration's National Helpline: 1-800-662-HELP. Credits: This episode was produced by Wendy Zukerman with help from Rose Rimler, Heather Rogers, and Shruti Ravindran. Our senior producer is Kaitlyn Sawrey. We’re edited by Blythe Terrell. Additional editing help from Alex Blumberg and Sruthi Pinnamaneni. Fact checking by Michelle Harris. Sound design by Emma Munger. Music written by Bobby Lord. Recording help from Amber Cortes. And a huge thank you to all the researchers and doctors who spent time with us. We really appreciate it. Dr Andrew Chang, Dr Michael Vagg, Dr Andrew Kolodny, Dr Michael Von Korff, Dr Mary Lynch, Prof Gary Franklin, Prof David J. Clark, Dr Andrew Rosenblum, Frank Lopez, the Zukerman family, and Joseph Lavelle Wilson.
We talk to Stanford law professor and economist John Donohue who for the better part of the last 20 years has been doing research into understanding gun violence.
