Fusion Breakthrough Once Thought Impossible Brings Energy Device Closer to Realization

Scientists have achieved a remarkable breakthrough in the conceptual design of twisty stellarators, experimental magnetic facilities that could reproduce on Earth the fusion energy that powers the sun and stars. The breakthrough shows how to more precisely shape the enclosing magnetic fields in stellarators to create an unprecedented ability to hold the fusion fuel together. “The key thing was developing a piece of software that allows you to rapidly try out new design methods,” said Elizabeth Paul, a Princeton University Presidential Postdoctoral Fellow at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and co-author of a paper that…

ULA’s Atlas V launches satellite-inspection mission for Space Force

Lead Image: The Atlas V is a “workhorse” for the military. Image Credit: Walter Scriptunas II United Launch Alliance carried out an Atlas V launch Friday with the third pair of GSSAP satellites for the US Space Force. Flying in its never-before-used 511 configuration, Atlas lifted off from Cape Canaveral Space Force Station at 2:00 PM EST (19:00 UTC) for a lengthy mission that injected the satellites into a near-geostationary orbit. The GSSAP (Geosynchronous Space Situational Awareness Program) is a US Space Force project using small satellites to inspect other spacecraft operating in geostationary orbit. Friday’s launch, which is designated…

How Climate Restoration Could be the Key to Stopping Climate Change

Lead Image: Our world is a pale blue dot, and we have just one world to live in. We should take care of her and she will do the same. Image Credit: NASA. The world today faces a mounting environmental crisis. Rising levels of CO2 are leading to global warming, the acidification of our oceans, and the destruction of ecosystems worldwide. Worse yet, these changes have led to feedback mechanisms that are making the situation worse. In short, Climate Change constitutes an existential threat that demands action. The extent of Climate Change and the dangers it poses are regularly cataloged…

HERA Telescope: Early Findings Promise Deeper Understanding of the Cosmic Dawn

Scientists including MIT’s Jacqueline Hewitt and Nicholas Kern share long-awaited results, getting closer to the universe’s first stars. All through history, humans have created and shared stories that ponder the creation of stars — what they are and how the first stars came to be. Now, with new results from the Hydrogen Epoch of Reionization Array (HERA), a radio telescope located at the South Africa Karoo Astronomy Reserve, MIT scientists are one small, but significant, step closer to understanding that history. HERA researchers are looking for the earliest signs of star formation and galaxy structure. Specifically, scientists including Jacqueline Hewitt,…

NASA’s NuSTAR Spots Highest-Energy Light Ever Detected From Jupiter – And Solves a Decades-Old Mystery

Lead Image: Jupiter’s southern hemisphere is shown in this image from NASA’s Juno mission. New observations by NASA’s NuSTAR reveal that auroras near both the planet’s poles emit high-energy X-rays, which are produced when accelerated particles collide with Jupiter’s atmosphere.

A new study finally reveals higher-frequency X-rays and explains why they eluded another mission 30 years ago. Scientists have been studying Jupiter up close since the 1970s, but the gas giant is still full of…
