The Mystery of Fast Radio Bursts!

Conversations with an Astrophysicist is back, with a very special guest: Emily Petroff. Emily is a PhD candidate at the University of Swinburne and is an expert in the field of the mysterious Fast Radio Bursts. Though astronomers still aren’t sure what they are, they’re learning more and more about them and how to detect them easier.

Pint in the Sky

Sometimes there’s nothing better than grabbing a pint with some friends. Now, what if those friends were astrophysicists? Pint in the Sky is precisely that, where Dr. Katie Mack and Dr. Alan Duffy have a relaxed conversation about some of the most fascinating things in the entire cosmos!

Know the Cosmos

We are not merely observers of the cosmos, but active participants in it. We are in the cosmos and the cosmos is in us. For us to better know ourselves, we must better know the cosmos.

Planetary Society Celebrates MAVEN's Launch

This article orginally appeared on Universe Today   If you can’t attend a rocket launch live, the next best thing might be watching it on a big screen, surrounded by fellow space fans. Today, as the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft sat atop an Atlas V rocket at Cape Canaveral, space lovers from southern California collected at the Crawford Family Forum in Pasadena California to watch the launch together. Our friends at the Planetary Society, along with Southern California Public Radio, hosted the free event, and an excited crowd of space enthusiasts of all ages attended the “launch party.” Mat Kaplan and Bruce Betts brought the witty banter that listeners of Planetary Radio are familiar with, while Emily Lakdawalla kept the entire forum current with up-to-the-minute updates of MAVEN in her pre-launch. Portions of Planetary Radio were recorded during the live broadcast, which gave the audience a treat, actually seeing how the radio program is created for special events such as the launch of a spacecraft. As the timer counted down to 20 minutes before launch, Casey Dreier called in over the big-screen. Casey, who’s the Advocacy and Outreach Coordinator of the Planetary Society, was on location at Cape Canaveral with the society’s president, Jim Bell. They both shared their experience leading up to the launch and stressed the need to continue planetary exploration in all of its forms. Moments after Bell ended the call, Bill Nye, The Science Guy himself, called in to the Crawford Family Forum. Replying to Kaplan’s question about excitement of ‘yet another’ Mars mission, Nye exclaimed, “What? How could there be such...

Introducing: Frontier Fields

Even though it’s been in service for 23 1/2 years, astronomers are still finding amazing new research to perform with the Hubble Space Telescope. The newest mission is called Frontier Fields and is already under way, doing things that seem only possible in science fiction. You see, astronomers will be pointing the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-Ray Observatory at galaxy clusters in order to use the gravitational lensing caused by its dark matter to look even further into the Universe, and thus even further back in time. The furthest we’ve been able to see in the optical wavelengths is around 13.2 billion years ago with the Hubble Extreme Deep Field, allowing us to see how the Cosmos was doing some 435 million years after the Big Bang, but that’s about to change. In fact, it already has! Hubble has already observed light from a galaxy that is from around 420 million years after the Big Bang! Since gravitational lensing is achromatic, that is it doesn’t affect the colour of the light that passes through it, astronomers will still be able to use colour to determine the age, chemical compositions and even red-shifts of the objects observed. Not only will we be discovering objects further back in time than we’ve ever seen, but the very use of gravitational lenses will give even further insight into how they and the dark matter they’re comprised of work. On October 24, Tony and I hosted a Hubble Hangout, introducing Frontier Fields to the public with many team members of the mission. The scientists described the different ways...

Hubble Releases New Comet ISON Observations

Today the Space Telescope Science Institute released new observations of Comet ISON taken with the Hubble Space Telescope. We are hosting a hangout, coinciding with the news release of this data, to discuss these observations and the latest about Comet ISON at 4pm EDT/1pm PDT. * Has ISON gotten brighter? * Is it breaking up? * Is it sprouting jets? * Will it survive perihelion? Please join Tony Darnell and Scott Lewis, along with Bonnie Meinke, Max Mutchler, Zolt Levay, Jian-Yang Li as they discuss these topics and your questions and comments about this oncoming comet.

Hubble Hangouts: The Orion Nebula

Update: Recording of the show! On 13 & 14 October, The Space Telescope Science Institute will host a workshop dedicated to the Orion Nebula. Talks and smaller presentations will discuss everything the wealth of ground-based and Hubble observations have taught us about this famous landmark in the sky. Tony Darnell and I will host a Google+ Hangout On Air event while a set of workshops at the Space Telescope Science Institute titled “The Orion Nebula Cluster — as a Paradigm of Star Formation” is being held in Baltimore. During the events, scientists will join the hangout from the workshops to discuss the star forming science of the Orion Nebula. As an added bonus, amateur astronomers from across the world have shared their favorite images of Orion that they’ve captured in their back yard observatories. RSVP to the Google+ event to be able to ask questions, make comments and interact with the hosts, scientists and everyone participating in this live event! To celebrate this event and to offer the attendees an opportunity to talk about their research to the general public, we are hosting two Hubble Hangouts on Monday and Tuesday and 6pm EDT to talk about (among other things): * What kind of stars are being born? * What can infrared observations tell us about Orion? * Ages and age spreads in the Orion Nebula * What does the nebula tell us about star formation? * What can the stars being born in Orion tell us about young star clusters in the galactic center? Interested in the kind of cutting-edge research that pushes the boundaries of our knowledge of this famous...

Space Fan News #112

In this week’s episode of Space Fan News, we talk about the exciting news of Voyager I entering interstellar space and learn about the new three-dimensional model of the interior of our Milky Way Galaxy. Here are the links for this week’s news stories: Voyager 1 in interstellar space Peanut Bulge Space Fan News is a collaboration between Deep Astronomy and Know The Cosmos. If you want weekly space and astronomy news updates, please subscribe to the DeepAstronomy channel. New episodes are uploaded every Friday night. Transcript:   Hello Space Fans! I’m Scott Lewis, and welcome to another edition of Space Fan News! A monumental point in human history was announced on the 12th of September, 2013 that the Voyager 1 spacecraft has entered interstellar space. Now NASA wants to make clear that this does not mean that the famous spacecraft has exited the solar system, for that requires it to move past the Oort cloud, which it hasn’t even entered yet. You see, Voyager 1 has broken through the heliosphere, a bubble of charged particles that surrounds our star which is created from coronal mass ejections. When CMEs occur on the sun, large amounts of plasma are shot outward in all directions at supersonic velocities. As it travels further out from the epicenter of the solar system, these charged particles reach a spot known as the Termination Shock. This is the area surrounding our star that interstellar winds start having an effect on the solar winds, slowing it down to subsonic speeds. The Termination shock is between 75 and 90 astronomical...
