The James Webb Space Telescope has spotted six likely rogue worlds — objects with planet-like masses but untethered from any star’s gravity — including the lightest ever identified with a dusty disk around it.

The elusive objects offer new evidence that the same cosmic processes that give birth to stars may also play a common role in making objects only slightly bigger than Jupiter.

University of Florida horticulture science professor Rob Ferl is going where some men have gone before, including William Shatner and Jeff Bezos, but he’s bringing along some experimental plant life for NASA.

Ferl, a researcher within UF’s Institute of Food and Agricultural Sciences, is also the director of UF’s new Astraeus Space Institute. He is joining five other people on the launch of Blue Origin’s suborbital New Shepard rocket today for what will be its eighth human spaceflight. Dubbed NS-26, the capsule is set for liftoff as early as 9:00 a.m. EDT from Blue Origin’s West Texas launch facility.

Along for the ride will be a species of plant called Arabidopsis thaliana. Ferl will be looking at how its genes adapt on the way to space.

Results could aid understanding of how black holes produce vast intergalactic jets. Scientists have observed new details of how plasma interacts with magnetic fields, potentially providing insight into the formation of enormous plasma jets that stretch between the stars.

Whether between galaxies or within doughnut-shaped fusion devices known as tokamaks, the electrically charged fourth state of matter known as plasma regularly encounters powerful magnetic fields, changing shape and sloshing in space...

Lunar igneous activities including intrusive and extrusive magmatism, and their products contain significant information about the lunar interior and its thermal state. Their distribution is asymmetrical on the nearside and farside, reflecting the global lunar dichotomy. In addition to previously returned lunar samples all from nearside (Apollo, Luna, and Chang’e-5), samples from the South Pole-Aitken (SPA) basin on the farside have long been thought to hold the key to rebalancing the asymmetrical understandings of the Moon and disclosing the lunar dichotomy conundrum.

Earlier this year, the Chang’e-6 mission of the Chinese Lunar Exploration Program, successfully launched on May 3, landed on the lunar surface on June 2, and returned to the Earth on June 25 carrying a total of 1935...
