An international team of astronomers has discovered the first radio-bright tidal disruption event (TDE) occurring outside a galaxy’s center using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) Very Large Array (NSF VLA) and Atacama Large Millimeter/submillimeter Array (ALMA), along with several partner telescopes.

First-ever Detection of “Heavy Water” in a Planet-forming Disk
The discovery of ancient water in a planet-forming disk reveals that some of the water found in comets—and maybe even Earth—is older than the disk’s star itself, offering breakthrough insights into the history of water in our Solar System.
Astronomers Detect Lowest Mass Dark Object Yet in Distant Universe
An international research team, using a worldwide network of radio telescopes, has detected an enigmatic dark object with a mass about one million times that of our Sun without observing any emitted light. This is the lowest mass dark object ever detected at a cosmological distance using only its gravitational influence.
The Universe just Became More Accessible: Free Software for Exploring the Universe Through Sound
Today free software has been released to help the blind and visually impaired (BIV) explore the universe through sound. With the support from the National Science Foundation’s STEM+C program, Innovators Developing Accessible Tools for Astronomy (IDATA) brought together nearly 200 BIV and sighted students, teachers, astronomers and programmers from across the Nation to create this innovative software called Afterglow Access. The software can be used through your web browser and is available via the Resources tab at https://idataproject.org. No software download is required for use.
Astronomy often brings to mind beautiful images of multicolored gas and dust giving birth to new stars and planets, incredibly detailed spiral arms in galaxies millions of light-years away, but many of these images are created by detecting the invisible spectrum of light. Astronomical images are generated by computers with light gathered from distant objects using telescopes and a variety of detectors. This light is converted into numerical data and computers use that data to generate the images we see. In reality, we are all “blind” to this data, and scientists have historically chosen to convert these numbers into images. The recently released Afterglow Access software is unique in that it gives the user the option to sonify this data turning numbers into audible notes instead of pictures.
IDATA students and teachers worked with a team of researchers to explore computation in astronomy through participation in user-centered design/universal design (UCD/UD) processes. The team iteratively developed and tested the software and learning resources , improving the accessibility for educational and professional uses.. The project builds on the success of prior NSF supported research, including the development of Afterglow, the Quorum programming language, and the Skynet Junior Scholars portal that supports collaborative astronomy investigations with the Skynet international network of telescopes.
Modern astronomy relies on computers and computational thinking for nearly every aspect of collecting, analyzing, and presenting data. Visual interfaces commonly used for these computational processes present unique challenges for blind and visually impaired (BVI) individuals. While BVI individuals are severely underrepresented across all fields of science, technology, engineering, and mathematics (STEM), the lack of vision-neutral tools in astronomy further increase the barrier-to-entry for BVI individuals.
“IDATA and Afterglow Access are the result of great teamwork between students and teachers and all of the partner institutions, but none of it would have happened without the support and vision of the National Science Foundation,” said Dr. Tim Spuck AUI’s STEM Education Development Officer. “This was a high-risk project and NSF believed in our team and we delivered. We are hopeful that with additional future support, we can continue this innovative and potentially transformative work.” Currently a team in Chile at Universidad Diego Portales is working to translate the software into Spanish allowing for greater accessibility in the BVI Spanish speaking community. The IDATA program and Afterglow Access envision using future versions of the software to sonify data in additional fields, including medicine and the geosciences.
IDATA is a program supported by the National Science Foundation (DRL #1640131) and managed through Associated Universities, Inc. (AUI). Along with AUI, major partner institutions on the project include GLAS Education, Linder Research & Development Inc., TERC, University of North Carolina at Chapel Hill, University of Nevada – Las Vegas, and Logos Consulting Group.
AUI collaborates with the scientific community to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public. Our expertise focuses on continually improving research and development, user facilities, management and operations, technology incubation, and community engagement through workshop and conference planning.
