Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies. The findings are published in the Monthly Notices of the Royal Astronomical Society.

The team of international astronomers, led by Newcastle University and Durham University, UK, used new data from the Dark Energy Spectroscopic Instrument (DESI), which is conducting a five year survey of large scale structure in the universe that will include optical spectra for ~3 million quasars; extremely bright galaxies powered by supermassive black holes...

A team of space scientists at the Planetary Science Institute, working with colleagues from the Chinese Academy of Sciences, Shenzhen University and the University of Aberdeen, has used data from China’s Chang’E-4 rover to learn more about the history of the moon. In their study, reported in the Journal of Geophysical Research: Planets, the group analyzed lunar-penetrating radar (LPR) data sent back from the rover.

China’s Chang’E-4 rover has been wandering around on the far side of the moon since 2018...

Using the world’s most powerful radio antenna, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.

The University of Queensland’s Dr Benjamin Pope and colleagues at the Dutch national observatory ASTRON have been searching for planets using the world’s most powerful radio telescope Low Frequency Array (LOFAR) situated in the Netherlands.

“We’ve discovered signals from 19 distant red dwarf stars, four of which are best explained by the existence of planets orbiting them,” Dr Pope said.

“We’ve long known that the planets of our own solar system emit powerful radio waves as their magnetic fields interact with the solar wind, but radio signals from planets outside our solar system had yet to be picked up.
