Astronomers have used the unique capabilities of NASA's Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic center that glows brightly as the black hole consumes material in its immediate surroundings.

Satellite-based and street-view green space and adiposity in US children

JAMA Network
Peer-Reviewed Publication

The results of this cohort study of U.S. children suggest that higher levels of satellite-based normalized difference vegetation index greenness and percentages of street-level green space components (flowers, plants, and fields) were associated with lower adiposity. The findings support the exploration of increasing residential green space levels and adding specific green space components as an urban planning and public health intervention strategy to combat the prevalence of childhood obesity in the U.S.

Will the Ross Ice Shelf melt? International team launches second attempt to drill for Antarctic climate clues

Binghamton University
Business Announcement

An international team of scientists -- including faculty at Binghamton University, State University of New York -- is undergoing an ambitious mission to obtain critical geological records from the West Antarctic Ice Sheet. The vast ice sheet holds enough ice to raise sea levels by 13 to 16.4 feet if it melts completely. Research has found a collapse might be inevitable for some parts of the West Antarctic Ice Sheet.

A rare Venus solar transit helps unravel exoplanet atmospheres

Faculty of Sciences of the University of Lisbon
Peer-Reviewed Publication

A team led by the Institute of Astrophysics and Space Sciences (IA) analysed data from this century’s last Venus solar transit and validated methods to study the atmosphere of Earth-sized exoworlds.
