Singapore is now the first country to have an art installation 7,000 metres beneath the ocean. It comprises three metal cubes designed by Singaporean artist Ms Lakshmi Mohanbabu, the first Singaporean to send her artwork into space on the International Space Station in 2022.

 Where do meteorites of different type come from? In a review paper in the journal Meteoritics & Planetary Science, published online this week, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid belt. 

“This has been a decade-long detective story, with each recorded meteorite fall providing a new clue,” said meteor astronomer and lead author Peter Jenniskens of the SETI Institute and NASA Ames Research Center. “We now have the first outlines of a geologic map of the asteroid belt.” 

Research by the Atacama Cosmology Telescope collaboration has put the standard model of cosmology through a rigorous new set of tests and show it to be remarkably robust. The new images of the early universe, which show both the intensity and polarization of the earliest light with unprecedented clarity, reveal the formation of ancient, consolidating clouds of hydrogen and helium that later developed into the first galaxies and stars.
