The American Astronomical Society (AAS) and partnering organizations Zenodo and the SAO/NASA Astrophysics Data System (ADS) has announced the launch of the Asclepias portal and broker, resources that connect software tools with scientific results to make research progress in astronomy faster, more open, and more reproducible.

Astronomers rely on scientific software to analyze data sets and model complex astrophysical objects and phenomena. But as the collection of astronomy-related software grows, it becomes increasingly difficult for scientists to discover relevant packages for data analysis, determine which software version was used in a specific study, or provide credit to the developer of the software used for a scientific discovery.

Asclepias combines different platforms to make these tasks possible. The project, funded by the Alfred P. Sloan Foundation, provides a connection point between the AAS, a community of astronomers who rely on a broad set of software packages to conduct their science; Zenodo, an open-access software repository where developers can upload their software projects; and ADS, a citation platform that allows astronomers to easily obtain references for different versions of software packages and track how the software is used and interlinked over time.

"Software has become critical to the advancement of science, but finding ways for astronomers to discover and reference the software that makes their science happen is challenging," says Mubdi Rahman (Sidrat Research), a member of the project team. "Asclepias was born out of this need to distribute, find, and track software as it is used in astronomy."

Asclepias's front end is an online search tool that allows users to query the system for specific software packages or search by keyword. Astronomers looking for the software tools used to analyze Hubble Space Telescope data, for instance, need only input "Hubble Telescope"' in the search form to discover the different software packages used for this purpose in past studies.

In the background, the newly launched Asclepias brokerconnects astronomy software packages on Zenodo with citations on ADS, providing links between scientific research articles and the specific software versions used to conduct the research. Though Asclepias could ultimately serve as a model of software and research interconnectivity for other scientific disciplines, astronomy provided an ideal testbed for this concept.

"The AAS is the natural group to gather community forces to work on software citation and discovery," explains Julie Steffen, AAS Chief Publishing Officer. Managing mountains of observed and simulated data, astronomers are heavy users of scientific software for analysis and modeling. This has motivated ongoing efforts by the AAS to encourage the preservation and citation of software in astronomical research literature.

"Software citations are important because they represent a key incentive in boosting open science practices," says Alexandros Ioannidis of Zenodo. "It's a way of giving credit where credit is due, rewarding those who make their software open and accessible." The use of open software is critical for researchers to be able to reproduce and verify scientific results.

"Over time, Asclepias will provide new insight into how astronomical software is used and evolves," adds Rahman. "Asclepias marks a first step toward enabling truly reproducible science and integrating software as a critical component of scientific research."

The Asclepias Project is a joint effort of the American Astronomical Society (AAS), the SAO/NASA Astrophysics Data System, Zenodo, and Sidrat Research, funded by a grant from the Alfred P. Sloan Foundation to AAS.

NASA embarks on 3-month alignment of Webb telescope's massive mirror
Washington DC (UPI) Feb 11, 2021
NASA has started the tedious, precise job of aligning 18 sections of the James Webb Space Telescope's giant golden mirror. The mirror had to be large enough to capture infrared light from the universe's earliest galaxies, but also had to be sectioned and folded in order to build and launch. Now, NASA engineers and astronomers will attempt to reposition all 18 hexagonal sections so they match up almost perfectly - to within 50 nanometers. A human hair is about 90,000 nanometers wide. ... read more
