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.

Partial Solar Eclipse – 23 October 2014

Here in Los Angeles, we’re pretty fortunate to have sunny skies the majority of the time, so when our Moon’s position is slightly placed between the line of sight between us and the Sun, it’s quite a big deal!   Today, this partial solar eclipse will occur starting at 2:10 p.m., be at its maximum at around 3:30 p.m. and then finally finish at 4:40 p.m. (all Pacific Daylight Time). During this eclipse, I will be on location at Cerritos College in Norwalk, California to broadcast a live view of the eclipse in its entirety. Dr. Thad Szabo will be conducting his regular lecture, but instead of in the hall, he’ll be gathering his students to directly observe the eclipse through filtered telescopes while also providing a special stream into our broadcast through a Coronado PST telescope. This telescope is special in that it blocks out all light except that which is emitted in Hydrogen Alpha, a particularly red-looking light that occurs when an electron falls from its third energy level to its second energy level, releasing a photon that has a precise frequency of 656.28 nm. This allows us to see the beautiful features on the surface of our star and will be even more beautiful when we watch the Moon travel across it. Joining me for commentary is Dr. Katie Mack from Melbourne Australia, who is waking up early to help explain the science of eclipses in all their forms to us while on air! The official event page is over on Google+, where the video stream will be embedded but also gives the opportunity for people to add...

Space Fan News! #139

  Astronomers have developed a new standardized method for measuring and cataloging stars and Curiosity celebrates its first Martian year! Oh and a special breed of Space Fans are building a new type of observatory-for Burning Man! Hello Space Fans! Welcome to another edition of Space Fan News! It seems like only yesterday that we were jumping up and down, celebrating the successful entry, descent and landing of the Mars Science Laboratory. Curiosity has now spent an entire Martian year, around 687 Earth days, on the surface of the red planet and has already surprised us with the information it’s sent back home. MSL arrived on Mars on 6 August 2012 inside the landing site known as Bradbury Landing which resides in Gale Crater. Curiosity was sent to Mars to help answer many questions revolving around the planet’s habitability for microbial life, either in the present or the past. Equipped with a state-of-the-art suite of scientific instruments including high-resolution cameras, atmospheric and environmental sensors, as well as four spectrometers including the famous laser of ChemCam, Curiosity really is a fully operational mobile laboratory on another planet. So what have these instruments told us about Mars in its first Martian year? Well for one, the question of whether Mars was ever hospitable to microbial life was answered quite early on in Yellowknife Bay, an ancient riverbed that was revealed to once host a lakebed of water as well as source of chemical energy that microbes on Earth metabolize. In short, it was an enormous “yes.” Mars once had an environment that would be hospitable to microbial life. To clarify, this...

    Stray light is affecting my favourite spacecraft while Hubble is being allocated to help out New Horizons, but to do what? Hello Space Fans! Welcome to another edition of Space Fan News! With just over a year left until New Horizons arrives at Pluto, the Hubble Space Telescope has once again been called into action to aid the mission. The New Horizons spacecraft launched in January of 2006. Since then, Pluto has been reclassified as a dwarf planet and four additional moons have been discovered, so what’s Hubble going to be doing? Well New Horizons is a flyby mission, meaning it won’t be orbiting its target like Cassini does with Saturn. This leaves a great opportunity for New Horizons to achieve: to survey Kuiper Belt Objects. The Hubble Space Telescope Time Allocation Committee has given the green light to observe areas in New Horizon’s flight path to look for these cold and icy objects beyond Pluto. Now KBOs are small and dark, but Hubble has the ability to detect objects that are relatively large, which would be prime candidates for New Horizons to visit after it leaves Pluto. The Hubble Team will be surveying a small area of the sky in that direction, moving with the estimated movement of the Kuiper Belt Objects, meaning that if KBOs are detected, they will look fairly stationary as the background stars streak across the frame in the background. KBOs in New Horizon’s flight path may be no larger than the isle of Manhattan and have very low albedo, meaning that it’s not very reflective of light and even more difficult...
