SAN ANTONIO Jan. 13, 2021 NASA has extended the Juno mission to explore Jupiter through September 2025, expanding the science goals to include the overall Jovian system, made up of the planet and its rings and moons. In addition to continuing to explore our Solar System s largest planet, NASA s planetary orbiter will rendezvous with three of the most intriguing Jovian moons. Since its first orbit in 2016, Juno has delivered one revelation after another about the inner workings of this massive gas giant, said Southwest Research Institute s Scott Bolton, Juno principal investigator. With the extended mission, we will answer fundamental questions that arose during Juno s prime mission while reaching beyond the planet to explore Jupiter s ring system and largest satellites.

Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. In fact, the most powerful explosions in the universe are gamma-ray bursts.
Now scientists have shown that GRB 200415A came from another possible source for short GRBs. It erupted from a very rare, powerful neutron star called a magnetar.

One of the Hubble Space Telescope s most iconic images is the Hubble Ultra Deep Field, which unveiled myriad galaxies across the universe, stretching back to within a few hundred million years of the Big Bang. Hubble peered at a single patch of seemingly empty sky for hundreds of hours beginning in September 2003, and astronomers first unveiled this galaxy tapestry in 2004, with more observations in subsequent years.
Since CO
2 has been recognized as the most important anthropogenic greenhouse gas owing to its significant impact on global warming and climate change, there have been a substantial number of studies that have focused on investigating the status of CO
2 in the atmosphere in the past and present, and how it will change in the future.
The United Nations Climate Change Conference (24th Conference of the Parties, COP24) will conduct a climate change action global stock-take for each of five years starting in 2023. Therefore, in support of these efforts, we need a new method to verify how much human emissions impact the global carbon cycle and climate change.
