Citizen science astronomy with a network of small telescopes: the launch and deployment of JWST

Astronomical Telescopes + Instrumentation, 2022
We present a coordinated campaign of observations to monitor the brightness of the James Webb Space Telescope (JWST) as it travels toward the second Earth-Sun Lagrange point and unfolds using the network of Unistellar digital telescopes.

Optically Sparse Primary Aperture Mirrors for Space-Based Earth-Observation Telescopes

IEEE International Geoscience and Remote Sensing Symposium, 2023
Scientific objectives from earth observation to astronomy require high-resolution observations from space-based platforms. However, designing space telescopes with large primary apertures to achieve high-resolution and high Signal-to-Noise Ratio ...

Novelty Detection on Radio Astronomy Data using Signatures

arXiv.org
We introduce SigNova, a new semi-supervised framework for detecting anomalies in streamed data. While our initial examples focus on detecting radio-frequency interference (RFI) in digitized signals within the field of radio astronomy, it is important to ...

Non-digital educational games to support conceptual change in astronomy education

Astronomy Education Journal
Research on astronomy education has primarily focused on investigating students' conceptual understanding through the lens of student cognition. However, learning involves more than just acquiring or reorganising ideas. Despite this, there have been very

The growing impact of unintended Starlink broadband emission on radio astronomy in the SKA-Low frequency range

Astronomy & Astrophysics
We present the largest survey to date characterising intended and unintended emission from Starlink satellites across the SKA-Low frequency range. This survey analyses ∼76 million full sky images captured over ∼29 days of observing with an SKA-Low ...

“Frog-eyes” in astronomy: Monitoring binary radial velocity variations through a pair of narrow-band filters

Science China Physics, Mechanics & Astronomy
Spectroscopic observations are a crucial step in driving major discoveries in the era of time-domain surveys. However, the pace of current spectroscopic surveys is increasingly unable to meet the demands of rapidly advancing large-scale time-domain ...
