Do X-ray Astronomers Wear Lead Aprons?
Dr. Patrick Slane from the Chandra X-ray Center presented an overview of the Chandra X-ray Observatory to NASA's museum alliance. This part of the conversation talks about how X-ray Astronomy connects to medical X-rays and what people experience with X-rays from the doctor.
-------------------
Everybody is familiar with going to the doctor and having a big X-ray machine kind of point at you and having a film put somewhere and then getting a picture. And at many times, I’ve been asked the question, is it dangerous to shine all those X-rays out in the space from Chandra.
The Coolest Things in the Universe...or, Impressing Your Co-Workers
Dr. David Pooley is an astrophysicist at the University of Wisconsin at Madison. Before landing at the home of the Badgers, Dave was at the University of California at Berkeley after getting his Ph.D. from MIT. He shares his thoughts on what's interesting in the Universe in this installment of the Chandra blog.

What Does the Future Hold?
Dr. Michael Muno continues his discussion in part II of his blog.
While focused on the present, Mike Muno, an astrophysicist at Caltech, has thoughts about where he would like to see his research go in the future. In this post, he discusses what he hopes to be studying with X-rays in the upcoming years.

The future holds several planned and proposed observatories that I am keen on using. In the medium term, I plan to work with data from an innovative X-ray telescope that will be one of the first to produce focused images in harder X-rays. That instrument,
Neutron Star Discovered Where a Black Hole Was Expected

Dr. Muno uses Chandra to study the black holes and neutron stars that are left behind when the largest stars exhaust their fuel and collapse. Read the blog
Finding Answers to Big Questions
Dr. Michael Muno is an astrophysicist who uses Chandra, among other telescopes, to study some of the most exotic objects in the Universe: white dwarfs, neutron stars, and black holes. He's currently a post-doctoral fellow at the Space Radiation Laboratory at the California Institute of Technology. He has spent time at both UCLA and MIT after receiving his Ph.D. from MIT in 1997.

Did you hear about this comet?
Dr. Scott Wolk is responsible for Monitoring & Trends Analysis of the Chandra X-Ray Observatory, working within the Development & Operations Group and Science Operations Team of the Chandra X-Ray Observatory Center. Scott discusses 17P/Holmes, a comet which was discovered November 6, 1892 by amateur astronomer Edwin Holmes. In October 2007 this comet became nearly one million times brighter, and is the largest known outburst by a comet.

Part II of Just Breathe: A Star's Death Exhales Oxygen Into Space
Dr. Patrick Slane from the Chandra X-ray Center recently shared some information on the G292.0+1.8 supernova remnant with NASA's museum alliance. Part II of this conversation talks more on what we're seeing in the Chandra image....
-------------------
Chandra Image of G292.0+1.8
The aftermath of the death of a massive star is shown in beautiful detail in this new composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image - easily the deepest X-ray image ever obtained of this supernova remnant - and in white is optical data from the Digitized Sky Survey. Although considered a "textbook" case of a supernova remnant, the intricate structure shown here reveals a few surprises. Just Breathe: A Star's Death Exhales Oxygen Into Space
