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 led to the clearest and most precise images yet of the universe’s infancy, the cosmic microwave background radiation that was visible only 380,000 years after the Big Bang. 

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.

It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without wearing headphones. In a new advancement in audio engineering, a team of researchers led by Yun Jing, professor of acoustics in the Penn State College of Engineering, has precisely narrowed where sound is perceived by creating localized pockets of sound zones, called audible enclaves. In an enclave, a listener can hear sound, while others standing nearby cannot, even if the people are in an enclosed space, like a vehicle, or standing directly in front of the audio source.

SAN ANTONIO — March 17, 2025 — New Southwest Research Institute-led modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit and spin properties have undergone significant evolution since. When NASA’s Lucy spacecraft flies by this approximately three-mile-wide space rock on April 20, 2025, the data collected could provide independent insights on such processes based on its shape, surface geology and cratering history.

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies.
