Podcasting Astronomy Every Day of the Year
The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes in duration, for all 365 days of the year. The podcast episodes are written, recorded and produced by people around the world. We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for the daily podcast. You can do as few as 1 episode or up to 12 episodes (one per month, subject to our editorial discretion). Our goal is to encourage people to sign up for a particular day (or days) of the year.
A monthly round up of the latest news in astronomy.
Monthly astronomy news, interviews and questions. Created by astronomers.
StarDate, the longest-running national radio science feature in the United States, tells listeners what to look for in the night sky, and explains the science, history, and skylore behind these objects. It also keeps listeners up to date on the latest research findings and space missions. And it offers tidbits on astronomy in the arts and popular culture, providing ways for people with many diverse interests to keep up with the universe.
Each week, Planetary Radio visits with a scientist, engineer, project manager, advocate or writer who can provide a unique perspective on the quest for knowledge about astronomy, our solar system and beyond. We also showcase regular features that raise your space IQ while they put a smile on your face. In addition, host Mat Kaplan is joined every week by Planetary Society colleagues Bill Nye the Science Guy, Bruce Betts, and Emily Lakdawalla to discuss the latest news about NASA and the Planetary Society. Visit our web site for an episode guide and broadcast directory.
Science meets comedy and pop culture on StarTalk Radio! Astrophysicist and Hayden Planetarium director Neil deGrasse Tyson, his comic co-hosts, guest celebrities and scientists discuss astronomy, physics, and everything else about life in the universe. Listen to StarTalk Radio podcasts on our website, www.startalkradio.net, and just about everywhere across the cosmos: iTunes, SoundCloud, Stitcher, Tune-In and more. You’ll also find us on YouTube, Facebook, Twitter, Google+, Tumblr, Instagram, Pinterest and other social media channels. Keep Looking Up!
Awesome Astronomy is the show for anyone and everyone who has even the slightest interest in astronomy and science. Join Ralph & Paul at the beginning of each month, for an informative and fun astronomy programme telling you what to look out (and up) for every month in the cosmos. You can be guaranteed a passion for astronomy, simple explanations of complex and fundamental topics, space and science news, absorbing interviews and listeners' astronomy questions answered. As both presenters have been accused of being a little skeptical in the past, you can also expect everything to be fact-based but frivolous. Join us on our journey to understand our universe!
What would happen if you fell into a black hole? How big is the universe? Just what the heck is a quasar, anyway? You've got questions, and astrophysicist Paul Sutter has the answers! Submit questions via Twitter using #AskASpaceman or post to facebook.com/PaulMattSutter. Every episode you will come closer to COMPLETE KNOWLEDGE OF TIME AND SPACE!
Hosted by Stuart Gary, StarStuff takes us on a weekly journey across the universe to see the death of stars and the birth of new worlds.

The astronomy and space exploration podcast
Astronomy Cast offers you a fact based journey through the cosmos. Each week Fraser Cain (Universe Today) and Dr. Pamela Gay (SIUE / Slacker Astronomy) take on topics ranging from the nearby planets to ubiquitous dark matter.
This is an astronomy based podcast/talk show that is devoted to stargazing tips, tricks and astronomical equipment. Do you have questions about how to get into astronomy? Do you have a favorite eyepiece that you want to discuss? What about an observing report that you can't wait to share? Are you shopping for a new telescope, and don't know where to start? Do you want to rant or rave about a specific telescope or astronomical accessory? Do you enjoy stargazing and do you take your telescope out every clear night? Well, At The Eyepiece is dedicated to you. We don’t focus on the science of astronomy, frankly there are plenty of shows/podcasts out there to do that. The focus of At The Eyepiece is the visual observer, those people that enjoy taking their telescopes under the stars, and those people wishing to join our ranks. After all, what really matters to a backyard stargazer is what’s At The Eyepiece.

The Moon cruises past the heart of the lion tonight. Regulus, the brightest star of Leo, stands above the Moon in early evening. The lion’s body trails off to the lower left of Regulus. It ends at the star Denebola — the tip of the lion’s tail. Denebola is almost twice as big and heavy as the Sun, and about a dozen times brighter. And it’s pretty young as stars go — about one-tenth as old as the Sun. Like a few other stars in its age and size range, Denebola is encircled by a broad disk of dust. Some of the tiny particles that make up the disk probably are left over from the cloud that gave birth to the star, while others may be debris from collisions between larger chunks of material — the size of asteroids or bigger. No one has detected planets amidst this debris. But astronomers have found gaps in the disk that could have been cleared out by the gravity of orbiting planets. If planets do exist, they probably formed as the dust grains stuck together to form bigger and bigger bodies...

We'll record our 30-minute show, and then stick around to answer your questions about space and astronomy. At the turn of the 20th Century, Einstein's theory of relativity stunned the physics world, but the experimental evidence needed to be found. And so, in 1919, another respected astronomer, Arthur Eddington, observed the deflection of stars by the gravity of the Sun during a solar eclipse. Here's the story of that famous experiment.

The life of a close binary system is a matter of give and take. Gas can be siphoned from one star to the other — an act that can radically change both stars. An example is Regulus, which is the brightest star of Leo, the lion. It stands to the lower left of the Moon at nightfall. Regulus consists of two pairs of stars. The members of one pair are small and faint. But the other pair is much more intriguing. It consists of the bright star that we see as Regulus, plus the dead core of a star that was once much brighter than Regulus itself. Originally, this star was the more massive member of the duo, so it aged much faster. As it neared the end of its life, its outer layers of gas puffed up to giant proportions. In fact, they got so puffy that the star couldn’t hold on to them. The gravity of the other star pulled some of the gas off its surface. As the gas fell onto the less-massive star, it transferred momentum from one star to the other. That made the star that was taking the gas spin much...

A giant lake spreads across the surface of Io, one of the big moons of Jupiter. You wouldn’t want to take a dip in it, though — it’s a pool of molten rock that sizzles at up to 2,000 degrees Fahrenheit. Io is about the same size as our own moon. But while the Moon is almost completely dead, Io is the most volcanically active body in the solar system. It’s heated by a gravitational tug-of-war between Jupiter and some of its other big moons. This conflict pulls and twists Io’s interior, melting some of its rock. Some of the molten rock pushes its way to the surface through volcanic mountains and lava lakes. Loki Patera is the largest of these volcanic features — a lake that covers about 7,000 square miles. Fresh lava bubbles up from below to fill its basin, which is shaped like a horseshoe. Over time, lava at the top of the lake cools and hardens to form a crust, so Loki Patera fades. But the crust is heavier than the molten rock below it, so it sinks, letting the hot lava rise to the surface...

What to look out, and up, for in April. This month we look in the direction of Leo the Lion for the beginners guide – taking a look at the bright binary stars and a very special grouping of entire galaxies to observe in our spring skies. Next we round up the planets that are visible in March 2015: Jupiter, Venus, Saturn and the return of Mercury. April brings us some nice lunar conjunctions and a well timed Lyrid meteor shower. And for our deep sky challenge we take you on a galaxy tour of Virgo and Coma Berenices.

The gibbous Moon passes through the middle of a triangle of bright astronomical objects tonight: the planet Jupiter, the star Procyon, and the “twins” of Gemini. The brightest point of the triangle is Jupiter, which is to the left of the Moon as darkness falls. Only the Moon and the planet Venus outshine it, so it’s easy to find. Jupiter shines so brightly because it’s the biggest planet in the solar system — about 11 times wider than Earth. And it’s wrapped in clouds that reflect about half of the sunlight that strikes them back out into space — giving this hefty planet a hefty appearance in the night sky. Procyon is the second-brightest member of the triangle, standing below the Moon. It’s the leading light of Canis Minor, the little dog. It’s only about 11 light-years away, which makes it one of our closer stellar neighbors. It’s actually two stars — the bright one that’s visible to the eye alone, and a “dead” companion that’s visible only through a telescope. The triangle’s final point...

A worldwide consortium will soon decide where to build a globe-spanning telescope array that could study some of the most energetic objects and events in the universe. If everything goes as planned, it’ll consist of a network of more than a hundred telescopes. About 20 of them will be in the northern hemisphere — in Arizona, Mexico, or the Canary Islands. But most will be in the southern hemisphere — in either Chile or Namibia. CTA — the Cherenkov Telescope Array — is designed to study gamma rays. They’re produced by exploding stars, hot gas around black holes, and other powerful events. They may even be created by collisions between particles of dark matter. Gamma rays produce flashes of blue light when they enter Earth’s atmosphere, and that’s what CTA will see. Scientists will study those flashes to learn more about the origin of the gamma rays. Under the current plan, the telescopes in the southern hemisphere will come in three sizes — from about 15 feet in diameter to as much as a...

Some giant radio dishes in Africa are getting a second life — they’re being reborn as radio telescopes. It’s part of an effort that will make southern Africa one of the leading sites in the world for radio astronomy. The project is using retired communication satellite dishes that have been replaced by fiber-optic cables. The dishes are about a hundred feet across. Engineers are refurbishing their pointing systems and adding instruments that will allow them to detect radio waves from stars and other objects. The first telescope was completed in Ghana, with three others in the refurbishment or planning stages. Each dish can act as an individual telescope, although the goal is to link them — and perhaps others — in a continent-spanning network. Such networks provide especially sharp views of the heavens. The project is also providing training for scientists, technicians, and students across Africa. That’s important because southern Africa will be home to half of the world’s largest radio...

A couple of tiny constellations wheel low across the south on early spring evenings — Pyxis, the compass, and Antlia, the air pump. Both are faint, though, so you need a star chart to find them. They were created by Nicolas de la Caille, a Frenchman who was one of the first astronomers to study the sky from southern Africa. He spent a couple of years at Cape Town in the 1750s, where he compiled a catalog of about 10,000 stars. Several other European astronomers visited southern Africa during the 18th and 19th centuries, studying objects that weren’t visible from the northern hemisphere. Britain even established a royal observatory there in 1820. Its astronomers toiled in unpleasant conditions for decades, yet they made important observations of stars and other objects, and helped measure the shape of our planet Earth. By the 20th century, though, astronomy in southern Africa was falling behind. The European governments that controlled much of the continent weren’t interested in scientific...

In the days before round-the-clock communications, Easter Sunday was one of the busiest days of the year for long-distance telephone calls. But 75 years ago today, many of those Easter calls to grandma and papa never got through. A giant storm on the Sun bombarded Earth, causing all kinds of trouble. The troubles were set in motion a few days earlier, when a magnetic storm on the Sun created a tremendous eruption. The blast sent billions of tons of charged particles racing through the solar system. The storm cloud took dead aim at Earth. Its leading edge hit on March 23rd, 1940, but the bulk of it slammed into the planet the following day — Easter Sunday. When it hit, Earth’s magnetic field funneled the charged particles toward the ground. They zapped an electrically charged layer of the atmosphere, knocking out long-range radio broadcasts. That deprived Americans of the latest news of the war in Europe. Even bigger problems came when the solar particles slammed into the ground, where they...

Hydra, the water snake, is the longest of the 88 modern-day constellations. It’s so long that it takes many hours for the entire thing to climb above the horizon. Yet Hydra is also one of the fainter constellations. In fact, from most cities, only one of its stars is easy to spot. Alphard is about a third of the way up the southeastern sky as night falls. There are no other bright stars anywhere near it, so you shouldn’t have much trouble picking it out. Alphard is about 175 light-years away. At that great distance, the fact that we can see it so clearly tells us that the star is pretty remarkable. In fact, it’s a giant — it’s puffed up to about 40 or 50 times the diameter of the Sun. The star is about 400 million years old — roughly one-tenth the age of the Sun. Yet it’s also about three times as massive as the Sun. Heavier stars “burn” through their nuclear fuel more quickly than less-massive stars, so they age more quickly. Alphard is already entering the final stages of life. As it...

The crescent Moon and the “evening star” stage a beautiful encounter this evening. They stand side by side as the Sun sets. They’re an especially beautiful sight before darkness falls, when they’re immersed in the glow of twilight. Despite its appearance, the evening star isn’t a star at all. Instead, it’s Venus, our closest planetary neighbor. Even before the invention of the telescope, skywatchers knew there was something different about this brilliant light. While the true stars all maintain their position relative to each other, Venus and the other “planets” change position from week to week or even night to night. In fact, that’s why they’re called planets — the name is the ancient Greek word for wanderer. Those wandering lights were a nuisance to those who tried to explain the workings of the heavens. Most thought that Earth was the center of the universe. And based on observations of how objects in the sky moved, that was a reasonable explanation for the Sun, Moon, and stars. But...

Modern-day Mars is cold and hostile. Dried-up riverbeds meander across the ancient Martian terrain, though, so rivers must have flowed across the planet billions of years ago. But that poses a bit of a puzzle, because Mars is half-again as far from the Sun’s light as Earth is. And when Mars was young, the Sun was much fainter than it is today. So how did Mars get warm enough for rivers to flow? A new idea may answer the question: punctuated volcanism. Artist's concept of Olympus Mons, the largest volcano on present-day Mars [NASA/MOLA team]Mars has plenty of volcanoes. In fact, its largest volcanoes dwarf any on Earth. And volcanic plains cover much of the Martian surface, indicating that Mars was volcanically active for much of its history. According to the new idea, giant eruptions took place about 3.7 billion years ago, releasing huge amounts of sulfur dioxide gas into the atmosphere. Like carbon dioxide, sulfur dioxide is a greenhouse gas, so it traps heat from the Sun. The new calculations...
Where did the oceans come from? Yeah, the answer is space, but are there any more details? Where does water come from anyway? Did the oceans come along with the earth or did they come later? Do we know anything about this at all? I discuss these questions and more in today's Ask a Spaceman! Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman, Twitter@PaulMattSutter, http://www.Facebook.com/PaulMattSutter, and http://www.askaspaceman.com for COMPLETE KNOWLEDGE OF TIME AND SPACE!

Light is tricky stuff, and it took scientists hundreds of years to puzzle out what this stuff is. But they poked and prodded at it with many clever experiments to try to measure its speed, motion and interaction with the rest of the Universe. For example, the Fizeau Experiment, which ran light through moving water to see if that caused a difference.

Sunrise at the north pole will experience a brief interruption early today — a total solar eclipse. The Moon will pass in front of the Sun, causing a small glitch at the start of a “day” that’ll last more than six months. Daytime is just getting started at the north pole because today is the March equinox — the beginning of spring in the northern hemisphere. We have seasons because Earth is tilted on its axis. As Earth orbits the Sun, the poles take turns nodding toward the Sun. The south pole nods sunward in December, and the north pole in June. But neither pole tilts sunward on the equinoxes. Because of this change in perspective, each pole sees six months of night followed by six months of daylight — or close to it. Because Earth’s orbit is slightly stretched out, there’s a slightly longer “day” for the north pole than for the south. And that day is extended even more by the way we mark sunrise and sunset. Officially, sunrise occurs at the moment the first bit of the solar disk peeks...
