High-energy transient signals are most often determined to be gamma-ray burst events, but the recently-launched Einstein Probe has expanded astronomers’ ability to quickly respond to similar signals occurring at X-ray wavelengths. Now, a multi-wavelength study of EP240408a concludes that while many of the signal’s characteristics might lead to the conclusion that it is a gamma-ray burst, the non-detection at radio wavelengths precludes that possibility.

Students Contribute to New Understanding of ‘Twinkling’ Pulsars
The flexible observing setup of the Green Bank Observatory’s 20-meter telescope enabled frequent, long-duration observations of eight pulsars, spanning two and a half years for a student-driven study carried out by students in the Pulsar Science Collaboratory program.
Double the Disks, Double the Discovery: New Insights into Planet Formation in DF Tau
Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them. A new study led by researchers at Lowell Observatory, combining data from the Atacama Large Millimeter/submillimeter Array (ALMA) and Keck Observatory, has unveiled intriguing findings about planet formation in this binary star system, known as DF Tau, along with other systems in this region.
ACEAP ambassadors visit NSF funded observatories in Chile
This last week a team of four outreach and education professionals from the United States undertook a 10-day expedition to key astronomy research sites in Chile. The outreach professionals were selected to be part of the 2018 Astronomy in Chile Educator Ambassadors Program (ACEAP), an immersive astronomy outreach and awareness program.
The core element of ACEAP is an in-depth, behind-the-scenes experience at major NSF-funded observatories in Chile, including the Cerro Tololo Inter-American Observatory (CTIO), the Atacama Large Millimeter/submillimeter Array (ALMA), the Southern Astrophysical Research (SOAR) telescope, and the Gemini South Observatory. In addition to learning about the different instruments, science, and research that comes out of these cutting-edge facilities, the Ambassadors also visited the Andean Astronomical Observatory (AAO), one of the largest private observatories offering astrotourism programs in the Santiago vicinity, Chile.
“Chile is rapidly becoming the astronomy capital of the world, providing a window to the universe and discoveries that benefit all of humanity. It’s important for astronomy educators and outreach professionals to experience for themselves this unique and special place that is home to modern-day astronomy.,” said Tim Spuck, principal investigator for the ACEAP project and education officer for Associated Universities, Inc.
ACEAP, which has 32 members to date, focuses on building a diverse and lasting community of educators who share their newfound knowledge and experiences with local communities through a range of formal and informal science-education activities.
The 2018 class of ACEAP ambassadors includes:
- Joel Goodman, an amateur astronomer and informal educator in Howard County, Maryland;
- Pat Hanrahan, Director of the Mt. Hood Community College Planetarium in Gresham, Oregon;
- Jack Howard; who teaches astronomy, physics, and math at community colleges in the Charlotte (NC) area, and serves as a volunteer outreach educator in NASA’s Solar System Ambassador program; and
- Rebecca Ljungren, a professional Astronomy Educator at the Smithsonian National Air and Space Museum and the Phoebe Waterman Haas Public Observatory.
The Astronomy in Chile Educator Ambassadors Program is a collaborative project of Associated Universities Inc. (AUI), the National Radio Astronomy Observatory (NRAO), Association of Universities for Research in Astronomy (AURA), the National Optical Astronomy Observatory, and Gemini Observatory, and is supported by the National Science Foundation.
The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.
