October is American Archives Month—a time to celebrate the importance of archives across the country. In honor of Archives Month, we're participating in a pan-Smithsonian blogathon. Throughout October we, and other blogs from across the Smithsonian, will be blogging about Chandra's rich archive of astronomical data, issues, and behind-the-scenes projects.

This past summer, I interned in the Chandra Education and Public Outreach department at the Smithsonian Astrophysical Observatory (SAO), where I spent several months sleuthing around the Chandra data archives as part of an on-going Astronomy Visualization Metadata (AVM) tagging project https://www.virtualastronomy.org/. AVM is data embedded into each image of astronomical objects that includes information such as the objects coordinates, the instrument and instrument settings used for capturing the image, and a description of the image. The goal of the project is to tag all the press release images from the Chandra X-ray telescope with metadata.

G299.2-2.9 is an intriguing supernova remnant found about 16,000 light years away in the Milky Way galaxy . Evidence points to G299.2-2.9 being the remains of a Type Ia supernova, where a white dwarf has grown sufficiently massive to cause a thermonuclear explosion. Because it is older than most supernova remnants caused by these explosions, at an age of about 4500 years, G299.2-2.9 provides astronomers with an excellent opportunity to study how these objects evolve over time. It also provides a probe of the Type Ia supernova explosion that produced this structure.

Summer at the Smithsonian Astrophysical Observatory in Cambridge, MA, is a perfect time for picking up projects that have been sitting on the back burner for a while. As activities slow down a bit, it's great to dig deeper into the Chandra data archive looking for a hidden gem; and when sifting through over 8 terabytes of data comprising more than 10,000 observations from one of NASA's "Great Observatories," you're bound to unearth more than a few.

High-mass stars are important because they are responsible for much of the energy pumped into our galaxy over its lifetime. Unfortunately, these stars are poorly understood because they are often found relatively far away and can be obscured by gas and dust. The star cluster NGC 281 is an exception to this rule. It is located about 9,200 light years from Earth and, remarkably, almost 1,000 light years above the plane of the Galaxy, giving astronomers a nearly unfettered view of the star formation within it.

The year 1905 was certainly a busy one for Albert Einstein. He had at least five papers published during that time. Not only would any scientist be proud to be so prolific, but Einstein was able to enjoy the fact these papers fundamentally changed the way we understood how the Universe worked.

Q: How can we detect black holes?

A: There are two basic ways we can detect whether there's a black hole. Black holes are, of course, dark by definition - not even light escapes them!

This graphic contains an image and illustration of a nearby star, named CoRoT-2a, which has a planet in close orbit around it. The separation between the star and planet is only about 3 percent of the distance between the Earth and the Sun, causing some exotic effects not seen in our solar system.

In this latest video blog, we sit down with Jessica Brodsky. Jessica is a student from Brown University who spent part of her summer doing detective work on the archive of Chandra images. Her task was to back fill the metadata into the Chandra images on chandra.si.edu. From her feedback, it was a useful experience, as Jessica's interests lie in digital assets management and web development. (We also heard that Jessica plans to take an astronomy course at Brown this year - awesome!).
