How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It’s a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
More massive than all the other planets combined, Jupiter truly is the king of our solar system. The swirling clouds, arranged in colorful, banded structures, change from year to year. The rich colors are produced by trace compounds in Jupiter’s predominantly hydrogen/helium atmosphere. Hurricane-force winds propel these clouds, and upwelling currents are ablaze with lightning bolts far more powerful than those seen on Earth.
The Hubble Space Telescope serves as a “weather satellite” for monitoring Jupiter’s stormy weather. The iconic Great Red Spot, a storm big enough to swallow Earth, shows that it’s shrinking a little in the Hubble images, but it still dominates the entire southern atmosphere, plowing through the clouds like a cargo ship.
Hubble astronomers patiently wait to get close-up snapshots as Earth make its nearest annual approach to Jupiter – an astronomical alignment called an opposition, when Jupiter is on the opposite side of the Earth from the Sun.
To improve the ability to forecast space weather, a multidisciplinary team of researchers, including Professor Boris Kramer at the University of California San Diego, received $3.1 million from the National Science Foundation. The researchers, led by Professor Richard Linares at the Massachusetts Institute of Technology, will also work on speeding up the forecasting abilities that are currently available.
Irvine, Calif., Sept. 10, 2020 – Through concerted, policy-driven efforts, China has converted large swaths of desert into grassland over the past few decades, but this success has come at a cost. In a study published recently in Nature Sustainability, scientists at the University of California, Irvine report that the Asian nation’s environmental reclamation programs have substantially diminished terrestrially stored water.
Astronomers using Hubble and the VLT have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why they have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new findings indicate that small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.
