Through funding from the U.S. National Science Foundation (NSF), Associated Universities Inc. (AUI), Tumble Media and the STEM Transformation Institute at Florida International University (FIU) are collaborating to support the STEM identity and literacy development of regionally and culturally diverse Latine families through podcast-initiated science talk at home. Seventeen episodes will be recorded for this project in Spanish and English.

Unlock the Secrets of the Invisible Radio Universe with SuperKnova
The NSF NRAO is excited to announce that, thanks to a generous grant from Amateur Radio Digital Communications (ARDC), learners can now enroll in two self-paced courses to learn the fundamentals of radio communications.
Astronomers Make Highest-Resolution Observations Ever from Earth
The Event Horizon Telescope (EHT) Collaboration has conducted test observations with the highest resolution ever obtained from the surface of the Earth. This feat was achieved by detecting light from distant galaxies at a frequency of around 345 GHz, equivalent to a wavelength of 0.87 mm. The Collaboration estimates that, in the future, they will be able to make black hole images 50% more detailed than before. This improvement will sharpen images of supermassive black holes, and allow astronomers to image more black holes than ever before.

For the last 15 years, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center has been using radio telescopes supported by the National Science Foundation— including those operated by NSF’s National Radio Astronomy Observatory— to turn a suite of millisecond pulsars into a galaxy-scale gravitational-wave detector. Millisecond pulsars are remnants of extinguished massive stars; as they spin hundreds of times each second, their “lighthouse-like” radio beams are seen as highly regular pulses. Gravitational waves stretch and squeeze space and time in a characteristic pattern, causing changes in the intervals between these pulses that are correlated across all the pulsars being observed. These correlated changes are the specific signal that NANOGrav has been working to detect.
NANOGrav’s most recent dataset offers compelling evidence for gravitational waves with oscillations of years to decades. These waves are thought to arise from orbiting pairs of the most massive black holes throughout the Universe: billions of times more massive than the Sun, with sizes larger than the distance between the Earth and the Sun. Future studies of this signal will enable us to view the gravitational-wave universe through a new window, providing insight into titanic black holes merging in the hearts of distant galaxies and potentially other exotic sources of low-frequency gravitational waves.

A public event discussing the results will take place on Thursday, June 29, 2023 at 1pm Eastern Time on YouTube Live.
