In Handprints on Hubble, retired astronaut Kathryn Sullivan describes her work on the NASA team that made all of this possible. Sullivan, the first American woman to walk in space, recounts how she and other astronauts, engineers, and scientists launched, rescued, repaired, and maintained Hubble, the most productive observatory ever built.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

Great Heroes and Discoveries of Astronomy takes you around the world and across time in search of the unsung heroes who, in many ways, are just as important to the story of astronomy as Hubble, Einstein, and Sagan. Whether they stood on the shoulders of giants or themselves offered shoulders for giants to stand on, the heroes of astronomy you’ll meet in these 24 lessons are a collective of the brightest and most daring minds in science.

Ever looked up at the night sky and wondered what’s really out there? On The Gravity of Questions, we dive into the mysteries of astronomy and astrophysics one curious thought at a time. From black holes and galaxies to the wildest “what ifs” about the universe, I’ll break it all down in a way that’s easy to understand, lighthearted, and fun to listen to. Think of it as stargazing with a friend who loves asking the big questions right along with you.

La física moderna ofrece numerosos avances sobre el origen y el funcionamiento del universo, conocimientos que se transmiten en forma de ecuaciones que, a menudo, nos parecen un galimatías. Con talento incomparable, Sean Carroll demuestra que esas ecuaciones son como verdaderos poemas repletos de significado que nos ayudan a descubrir un milagroso paisaje multidimensional de gigantes radiantes, espacio-tiempo deformado, agujeros negros o fuerzas increíblemente poderosas, y, en suma, que son accesibles a cualquier persona con estudios de matemáticas de secundaria.

For the first time in four billion years of life on Earth, we are preparing to step out among the stars, not just as lone astronauts or billionaire tech bros, but as a civilization. Dr Adriana Marais has dedicated her life to preparing form extraplanetary settlement, and here, she considers not just the scientific concerns of a multiplanetary existence (like terraforming and life-support systems), but also the ethical responsibilities we must carry with us as we explore new frontiers.

As command module pilot of Apollo 17, the last crewed flight to the moon, Ron Evans combined precision flying and painstaking geological observation with moments of delight and enthusiasm. As a patriotic American in charge of command module America, Evans was nicknamed “Captain America” by his fellow crew members.

The Magellanic Clouds drift across the southern sky like luminous islands—near enough to be seen with the naked eye, yet vast enough to hold billions of stars. For millennia they have been woven into the stories of Indigenous peoples, guiding navigators across oceans and inspiring myths of creation. For modern science, they are living laboratories, revealing how galaxies are born, shaped, and ultimately transformed.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

Mars - bewilderingly empty, coated in red dust - is an unlikely place to pin our hopes of finding life elsewhere. And yet, right now multiple spacecraft are circling, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium and Mare Sirenum - on the brink, perhaps, of a discovery that would inspire humankind as much as any in our history. With poetic precision and grace, Sarah Stewart Johnson traces the evocative history of our explorations of Mars.

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

Ed Dwight: A Trailblazer's Journey from Astronaut Trainee to Space Traveler Edward Joseph Dwight Jr., commonly known as Ed Dwight, was born on September 9, 1933, in Kansas City, Kansas, during an era marked by deeply entrenched racial segregation and widespread discrimination against African Americans. Growing up in this challenging environment, Dwight faced numerous obstacles and barriers to success, but his parents instilled in him a strong sense of determination, a commitment to hard work, and an unwavering belief in the power of education to transform lives. Dwight's father, Ed Dwight Sr.,...

In The New Camelot, Frank White explorers the nature of the Camelot myth and how it relates to the modern day space program. This leads to a surprising insight into how humanity's future in the stars may unfold.

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

Not long ago, the Solar System was the only example of a planetary system - a star and the bodies orbiting it - that we knew. Now, we know thousands of planetary systems, and have even been able to observe planetary systems at the moment of their birth.

Mars is back. Suddenly everyone - from Elon Musk to Ridley Scott to Donald Trump - is talking about going to the Red Planet. When the Apollo astronauts walked on the Moon in 1969, many people imagined Mars would be next. However NASA’s Viking 1, which landed in 1976, was just a robot. The much-anticipated crewed mission failed to materialise, defeated by a combination of technological and political challenges.
