An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in Astronomy & Astrophysics, is remarkable as it sheds new light on the formation and stability of planets in double-star environments, which have long been considered hostile to the development of complex planetary systems.

The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of the longest-standing mysteries in modern astrophysics. A leading hypothesis suggests that “explosive transients,” including massive stellar explosions (supernovae) and tidal disruption events (TDE) caused by stars being torn apart by black holes, could be the cosmic engines driving these energetic particles. Yet, this idea has never been rigorously tested.

A research team led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has used the Tianma Radio Telescope to conduct multi-band radio observations of the returning comet 12P/Pons-Brooks (12P). They measured its water production rate during outburst activities and made the most distant detection of ammonia molecules in a Halley-type comet to date. The findings are published in Astronomy & Astrophysics.

Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the sun’s corona—elusive magnetic waves that scientists have been searching for since the 1940s.

An international team of astronomers has created the first-ever large-scale maps of a mysterious form of matter, known as CO-dark molecular gas, in one of our Milky Way’s most active star-forming neighborhoods, Cygnus X. Their findings, using the Green Bank Telescope (GBT), are providing crucial new clues about how stars formed in the Milky Way.
