Chandra "Enthusiastically Endorsed" for Extension in Senior Review

Peter Edmonds is the Chandra Press Scientist and, in addition to his work on publicizing Chandra science, has been heavily involved with the Chandra's Senior Review proposal since 2008.

In science, "peer review" is used to describe a process that determines whether a research paper should be published in a journal. One or more experts review the paper and determine its fate: are the results and discussion reliable and do they meet the publication standards of the journal?

Core-Halo Age Gradients in Young Stellar Clusters

We are delighted to welcome a trio of guest bloggers to discuss their work related to the newest Chandra press release on star clusters and star formation. Konstantin Getman, Eric Feigelson, and Michael Kuhn are colleagues at Penn State University and are all involved in the Massive Young Star-Forming Complex Study in Infrared and X-ray (MYStIX) project led from that institution.

NASA's Chandra Delivers New Insight into Formation of Star Clusters

Flame Nebula

Stars are often born in clusters, in giant clouds of gas and dust. Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work, as described in our latest press release.

Professional and Amateur Astronomers Join Forces


We are perhaps living in the midst of a new "Golden Age" of astronomy. In the four hundred years since Galileo first trained his refracting optical telescope on the Moon, and Jupiter and its moons, we've seen staggering advances in the technology of telescopes. We've also benefited from the discoveries of light beyond the visible portions of the electromagnetic spectrum and the development of instruments sensitive to those wavelengths.

Supernova Cleans Up its Surroundings


Supernovas are the spectacular ends to the lives of many massive stars. These explosions, which occur on average twice a century in the Milky Way, can produce enormous amounts of energy and be as bright as an entire galaxy. These events are also important because the remains of the shattered star are hurled into space. As this debris field - called a supernova remnant - expands, it carries the material it encounters along with it.

Dr. Belinda Wilkes Chosen to Lead the Chandra X-ray Center

Professor Charles Alcock, Director of the Harvard-Smithsonian Center for Astrophysics, announces that after an extensive search, the Smithsonian Astrophysical Observatory (SAO), in consultation with NASA, has selected Dr. Belinda Wilkes as the next director of the Chandra X-ray Center (CXC). She will assume the directorship on April 20, 2014.

What Makes an Astronomical Image Beautiful?

Astronomy is renowned for the beautiful images it produces. It's not hard to be impressed by an image like the Pillars of Creation or the Bullet Cluster, and the more eye-catching an image is, the bigger an audience it can potentially reach. So, as part of our job in astronomy outreach, we have each spent time thinking about what makes an astronomy image beautiful. As professionals, we’d like to go well beyond the intuition of the person who says, "I don't know anything about art, but I know what I like". One approach(1) is to list the key elements that make an image beautiful.
