Precise orbit determination is becoming increasingly critical for satellite navigation, positioning and timing as Low Earth Orbit constellations expand worldwide. Researchers have introduced a new method that combines inter-satellite link data with onboard BeiDou-3 observations to simultaneously resolve LEO and BeiDou-3 Medium Earth Orbit satellite orbits with unprecedented accuracy.

Supernovae are sudden stellar explosions that flare brightly in the sky, making them difficult to capture in their earliest moments. With modern wide-field, high-cadence sky surveys, astronomers can now spot these events almost daily, but protocols are needed to secure immediate follow-up data.

Supernovae appear to our eyes-and to astronomical instruments-as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion of a star. Because supernovae are sudden and unpredictable, they have long been difficult to study, but today, thanks to extensive, continuous, high-cadence sky surveys,
