Building a Global Astrotourism Community of Practice Through Astronomy for Development
arXiv:2606.00303v1 Announce Type: cross Abstract: Astrotourism is an emerging interdisciplinary field situated at the intersection of astronomy, tourism, cultural heritage, and sustainable development. Despite growing global interest, the field remains loosely defined and under-theorized, with limited empirical studies documenting practitioner perspectives and community-led initiatives. This paper presents findings from the first Astrotourism Community Exchange hosted by the International...
Gravitational-wave astronomy with a space-based optical clock network
arXiv:2606.01516v1 Announce Type: cross Abstract: Since the first detection of a merging binary black hole system a decade ago, gravitational-wave astronomy has emerged as a powerful tool for astrophysics. Future space-based observatories, such as the Laser Interferometer Space Antenna (LISA), will unlock the millihertz (mHz) band, which remains entirely inaccessible to ground-based detectors due to terrestrial noise. In parallel, proposed atom-based gravitational-wave detectors,...
How China is working to turn Saishiteng Mountain into the world’s largest astronomy base
Construction on the Tibetan plateau of some of the Earth’s most powerful optical telescopes is putting China on track to house the world’s biggest astronomy base by the mid-2030s, according to project scientists. Deng Licai, lead scientist for site planning at the National Astronomical Observatories of China (NAOC) in Beijing, said the telescopes at Saishiteng Mountain in northwestern Qinghai province would stretch between 6.5 metres (21.3 feet) and 14.5 metres across, and partner with...
The OAD Flagship Ecosystem
arXiv:2606.03966v1 Announce Type: cross Abstract: The International Astronomical Union's Office of Astronomy for Development (IAU OAD) uses astronomy as a tool to address societal challenges and contribute to sustainable development. Building on more than a decade of project funding and implementation, the OAD has developed a portfolio of flagship projects that represent tested and scalable applications of Astronomy for Development across thematic areas including socio-economic development,...
The next-generation Very Large Array prototype gathers its first light
The next-generation Very Large Array prototype gathers its first light Lisa Lock Scientific Editor Andrew Zinin Lead Editor The Very Large Array, the iconic field of radio antennas featured in the film "Contact" (inspired by Carl Sagan's novel), has a long and distinguished history of service. But after more than 45 years of studying the radio sky and probing the mysteries of the universe, the U.S. National Science Foundation National Radio Astronomy Observatory, which operates the VLA, is...
Brightness 'gap' in ancient star cluster reveals missing red dwarfs
Brightness 'gap' in ancient star cluster reveals missing red dwarfs Gaby Clark Scientific Editor Robert Egan Associate Editor Scientists from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, sought to study one stellar subject and ended up finding something even more exciting. The team's results published today in Astronomy & Astrophysics. Using data from the European Space Agency's (ESA's) Euclid space telescope and NASA's Hubble Space Telescope, the team planned to...
A stellar “Rosetta stone” reveals the source of mysterious cosmic signals
A stellar “Rosetta stone” reveals the source of mysterious cosmic signals A star caught cannibalizing its companion has finally revealed the origin of one of astronomy’s most puzzling repeating signals. - Date: - June 2, 2026 - Source: - University of Sydney - Summary: - Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years.
Small Magellanic Cloud is being pulled apart, reshaping how astronomers read its past
Small Magellanic Cloud is being pulled apart, reshaping how astronomers read its past Gaby Clark Scientific Editor Robert Egan Associate Editor Using more than a decade of observations from the VISTA Survey of the Magellanic Clouds (VMC), researchers measured the motions of millions of stars across the Small Magellanic Cloud with unprecedented precision. The new study, published in Astronomy & Astrophysics, provides direct evidence of a galaxy-wide tidal disruption of the Small Magellanic...
Celestron StarSense Explorer LT 70AZ review
Celestron StarSense Explorer LT 70AZ review From lunar detail to planets and bright deep-sky objects, we test what the Celestron StarSense Explorer LT 70AZ can actually show beginners and kids. A nice little telescope for beginners and kids who are interested in the night sky and want something compact and portable. It’s a great starter scope, but not necessarily one you’ll stick with long-term as your passion for astronomy grows. - +
