How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around […]

For the first time, scientists have directly tracked the slow transformation of a dying star over more than a century—revealing it is heating up faster than any other typical star ever observed.

In the past decade, astronomers have witnessed three interstellar objects (ISOs) passing through the solar system. These include the enigmatic ‘Oumuamua in 2017, the interstellar comet 2I/Borisov in 2019, and 3I/ATLAS in July 2025. This latest object also appears to be a comet, based on recent observations that showed it was actively releasing water vapor […]

The Three-Body Problem isn’t just the name of a viral Netflix series or a Hugo Award-winning sci-fi book. It also represents a real problem in astrodynamics—and one that can cause headaches for mission planners in terms of its complexity, but also one that offers the promise of an easier way to enter stable orbits that […]

A University of Queensland researcher has developed a new mathematical model to explain the evolution of the universe which, for the first time, includes collapsing regions of matter and expanding voids.

The NASA Soil Moisture Active Passive (SMAP) mission, launched in 2015, has over 10 years of global L-band radiometry observations. The low frequency [1.4 GHz frequency or 21 cm (8 in) wavelength] measurements provide information on the state of land surfaces in all weather conditions—regardless of solar illumination.

Compact, reflective, easy-to-manufacture mirrors are a critical component for advancing astronomical technology in space. Mirrors are a key component in most telescopes, though they are notoriously hard to manufacture with the necessary precision, especially at large scales. A new paper posted to the arXiv preprint server from researchers in the U.K. uses additive manufacturing to […]
