Specifically, Jupiter’s strong magnetic field caused the formation of a magnetospheric cavity in the circumplanetary disk around the young gas giant, which likely captured the moons Io, Europa, and Ganymede. In contrast, the young Saturn’s magnetic field was too weak to form a cavity, so the migrating moons cannot survive in the disk.
To better understand these reactions, Wang’s team, which includes researchers from six universities in the United States, China, and the United Kingdom, studied the isotopic makeup of chlorine, oxygen, and carbon produced by these discharges. They found a consistent depletion of heavier isotopes across all three elements.
The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. Discovered by Giovanni Battista Hodierna before 1654, it is one of only two star-forming nebulae faintly visible to the naked eye from mid-northern latitudes. While appearing pink in long-exposure photographs, it typically appears gray when viewed through binoculars or telescopes due to the human eye’s limited color sensitivity in low-light conditions. In the foreground is the open cluster NGC 6530.
This mosaic strip – extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14, 2015 – now includes all of the highest-resolution images taken by the NASA probe.
A new proposed satellite constellation could turn the night sky into permanent twilight – or even daylight – should a “visionary” startup’s plans come to fruition. Never mind that the Soviets tried it in the 90s before deciding it was a terrible idea, as should be obvious to most people without having to give it too much thought. Still, if it allowed the US to put an end to daylight savings time changes, I might be onboard with it.
As of writing this article, there are about 14,000 satellites orbiting our planet — nearly 10,000 of which belong to SpaceX — and the number is going to increase aggressively as commercial interests in this realm continue to grow.
Due to the equinox effect, there’s approximately a double chance of seeing the northern lights, as the sun likely reached the end of a period of solar maximum activity in 10/24
Managing this massive amount of data is a critical part of the VRO. The dense data stream flows through purpose-built fiber optic cables from the observatory to Santiago, Chile’s capital city. From there it travels to Miami, Florida, then flows through existing high-speed infrastructure to the Rubin Observatory United States Data Facility (USDF) at SLAC National Accelerator Laboratory in California. Finally, the data flows through a dedicated, encrypted network to a United States Intelligence Community facility in California.
Organic molecules discovered within a stone on Mars cannot be fully explained by nonbiological processes, and it’s “reasonable to hypothesize” that living things could have formed these odd organic molecules, a NASA-led team reports in a new study. However, this doesn’t mean scientists have found definitive proof of life on Mars, they cautioned.
