NASA Blueshift

To kick off our special summer series about data, we interviewed 2006 Nobel Laureate John Mather about the importance of imagery in communicating science and sharing data with the public. More than just "pretty pictures," data can be used to tell a story and explain the mysteries of the cosmos. Not every piece of data would be considered a work of art, but the information contained is at the very heart of NASA science. Working with COBE and the James Webb Space Telescope, Dr. Mather is no stranger to the power of data and the importance of scientific imagery. We got the scoop on how data is used in communication and why every bit of data is beautiful in its own way.

The telescope on everyone's mind during this month's Space Shuttle flight was certainly the Hubble Space Telescope, as astronauts inspected, repaired, and upgraded the satellite for years of additional scientific observations. But two additional telescopes were aboard Atlantis for this historic flight - a museum-quality replica of one of Galileo's telescopes, and a 200-year-old telescope built by master craftsman Jesse Ramsden. To give you the scoop about these telescopes, we interviewed Marvin Bolt of the Adler Planetarium. Hubble may be NASA's best-known telescope, but it wouldn't be here without 400 years of innovation.

NASA is famous for its acronyms and technical jargon. If you've ever watched a rocket launch or a spacewalk, you've heard some of them. Blueshift is produced by the ASD EPO team at NASA GSFC - that is, the Astrophysics Science Division Education and Public Outreach team at NASA Goddard Space Flight Center. Do we need to spell out NASA, too? In this episode, we explore NASA mission names and where they come from. And we make a very special dedication - this one's for you, Stephen Colbert!

Join Blueshift for a unique tour of the solar system, as we walk the B and A Trail's Planet Walk in Maryland and talk to scientists along the way. Armed with hiking boots and a portable recorder, Francis Reddy brings you the sounds of the solar system and a factoid about each planet along the way. Also featuring the Sun and lonely former-planet Pluto! Recorded during the 100 Hours of Astronomy earlier this month, this episode gives you a taste of the activities organized by NASA Goddard Space Flight Center and its community partners.

In astrophysics, the development of innovative technology is crucial to answering scientific questions about the Universe around us. The types of technology invented are determined, at least in part, by the answers we are seeking. At the heart of this science-technology cycle are "professional tinkerers," scientists and engineers that balance the needs of the astrophysics field and the opportunities afforded by an impressive palette of tools. In this episode, we interviewed Dr. Harvey Moseley, one of the "tinkerers" here at NASA Goddard Space Flight Center. He gave Blueshift some advice on how to take inventions from the drawing board to reality.

2009 has been chosen as the International Year of Astronomy because it marks the 400th anniversary of a big event in astronomical history - the first recorded observations of the night sky with a telescope. Galileo Galilei pointed his telescope at the Moon, the stars, and Jupiter, and changed our perceptions of the Universe forever. In celebration, there will be a variety of special events throughout 2009. The first big global event will be the 100 Hours of Astronomy, held April 2-5, 2009. In honor of this special year, we decided to interview Galileo himself about what he did and why it was important to astronomy. We hope you'll look into 100 Hours of Astronomy events in your own area, and perhaps take a look through a telescope yourself.

HD 80606b would not be a fun place to live, with its high winds, intense storms, and temperatures thousands of degrees hotter than any region on Earth. This exoplanet goes on a wild ride around its host star, with an orbit that takes it extremely close - and then extremely far away. This sends the planet through rapid heating and cooling cycles that astronomers are keenly studying to learn more about planetary atmospheres and climate patterns. In this episode, we interviewed Dr. Drake Deming, a Goddard astronomer studying HD 80606b, about this extreme planet and what makes exoplanets so interesting and valuable to observe. Though it isn't a friendly place, this extreme planet may be a step along the way to finding another world much like our own.

Have you ever wondered where Google Sky gets the data that lets you pan and zoom your way around the cosmos? Much of it comes from NASA's SkyView Virtual Observatory, a database of astronomy data from a variety of different sources. Google Sky and WorldWide Telescope are two sites that access the database for users, but anyone can use SkyView directly with just a web browser! It's like having a powerful - and versatile - telescope at your fingertips, ready to show you whatever you'd like to see in the Universe. We interviewed Tom McGlynn, the creator of SkyView, about what this powerful virtual telescope can do and how people are using it. Hunt for near-Earth asteroids, research a homework assignment, check out multiwavelength data... or just play!

This episode features a strange signal from deep space, which could be a plot straight out of a Hollywood film. But this radio signal was detected by a NASA mission called ARCADE, which flew above the atmosphere suspected from a balloon to capture light from the first stars and galaxies that formed in the Universe. When data showed something totally unexpected, that's when things got interesting. We interviewed Al Kogut and Dale Fixsen about this discovery, ARCADE, and how you can also detect this mysterious radio signal from outer space with any FM radio.

After taking some time off to seek listener feedback and consider the future direction of our podcast, Blueshift is back with a new episode to kick off 2009! For our re-launch, we've focused our first episode on another recently launched NASA project - the Fermi Gamma-ray Space Telescope - and the exciting gamma-ray bursts that it observes.

Welcome to the December 2007 episode of Blueshift, from NASA Goddard Space Flight Center. We're celebrating the new year with a look at the typical life cycle of NASA missions and the typical day of our science staff. We'll start with a look back at the FUSE mission, which ceased operations earlier this year. Then we'll give you an inside look at what it takes to make a mission happen - from the birth of ideas to the day-to-day operation of a satellite after launch.

Welcome to the November 2007 episode of Blueshift, from NASA Goddard Space Flight Center. This month, find out what it's like to spend a summer vacation at NASA in interviews with some of our 2007 interns. Also, join us for a birthday party that's out of this world... happy 10th birthday, ACE! And finally, we'll share the answer to the Episode 4 brain teaser.

Welcome to a special episode of Blueshift! As we approach another year of Nobel Prizes, we are releasing our full-length interview with NASA's own Nobel Laureate, John Mather (an edited version appeared in Episode 4). Learn more about cosmology, Dr. Mather's new position at NASA Headquarters, the importance of small missions, and the exciting future of the James Webb Space Telescope.

Welcome to the July 2007 episode of Blueshift, from NASA Goddard Space Flight Center. Catch up on the latest astronomy headlines, and listen to our audio scrapbook from the American Astronomical Society meeting in Hawaii. For this episode, we interviewed Dr. John Mather, co-winner of the 2006 Nobel Prize in Physics. Dr. Mather talks about cosmology, NASA missions, winning the Nobel Prize, and his induction into a little-known Swedish student organization. We've also got a new brain teaser - and we're eagerly awaiting your answers at our website!

Welcome to the June 2007 episode of Blueshift, from NASA Goddard Space Flight Center. We're featuring X-ray astronomy this episode - listening to black holes and learning about what it takes to build an X-ray telescope. We interviewed Jerry Bonnell, co-curator of the Astronomy Picture of the Day, for a behind-the-scenes look at the website. We'll wrap things up with a new question from the mailbag, and a brain teaser.
