A team of researchers used 3D particle simulations to model the acceleration of ions and electrons in a physical process called magnetic reconnection. The results could contribute to the understanding and forecasting of energetic particles released during magnetic reconnection, which could help protect space assets and advance space exploration. "For the first time ever, we can use 3D simu

When two galaxies collide, the supermassive black holes at their cores release a devastating gravitational "kick," similar to the recoil from a shotgun. New research led by CU Boulder suggests that this kick may be so powerful it can knock millions of stars into wonky orbits. The research, published Oct. 29 in The Astrophysical Journal Letters, helps solve a decades-old mystery surrounding

Now that NASA's James Webb Space Telescope has safely arrived at its launch site in French Guiana, on the northeastern coast of South America, technical teams have begun making progress on the final checklist of preparations before liftoff later this year. These preparations are expected to last 55 days from the observatory's arrival by ship to the day of launch. After Webb arrived a

Astronomers have discovered thousands of planets orbiting stars in our galaxy - known as exoplanets. However, it's difficult to know what exactly these planets are made of, or whether any resemble Earth. To try to find out, astronomer Siyi Xu of NSF's NOIRLab partnered with geologist Keith Putirka of California State University, Fresno, to study the atmospheres of what are known as polluted whit

Advanced manufacturing experts from Manchester have revealed what human life in space could look like - with a graphene-enhanced space habitat developed to meet anticipated demand for human settlements beyond Earth. A community of specialists at The University of Manchester have teamed up with global architect firm Skidmore, Owings and Merrill (SOM) to research the design and manufacturing

NASA is in the final stages of preparation to launch the nearly $10 billion James Webb Space Telescope, an engineering marvel that may reveal secrets of time and the universe, from South America on Dec. 18. Technicians are preparing to load the space observatory with fuel that will power it for up to 13 years as it orbits the sun about one million miles from Earth, NASA officials said T

Around 12,000 years ago, something scorched a vast swath of the Atacama Desert in Chile with heat so intense that it turned the sandy soil into widespread slabs of silicate glass. Now, a research team studying the distribution and composition of those glasses has come to a conclusion about what caused the inferno. In a study published in the journal Geology, researchers show that samples o

Move over, Hollywood - science fiction is getting ready to leap off the big screen and enter the real world. While recent science fiction movies have demonstrated the power of artificially intelligent computer programs, such as the fictional character J.A.R.V.I.S. in the Avenger film series, to make independent decisions to carry out a set of actions, these imagined movie scenarios could now be

The lunar surface is covered by numerous craters that date back to the impacts of asteroids. Age determinations on lunar rocks formed during these impacts show a surprising clustering at ages of about 3.9 billion years before present, or about 500 million years after the Moon was formed. These observations have led to the theory of a Late Heavy Bombardment of the Moon (or LHB). But what wa

Abundant geological evidence demonstrates that Earth's climate has experienced millennial-scale variability superimposed on glacial-interglacial fluctuations through the Pleistocene. The magnitude of millennial climate variability has been linked to glacial cycles over the past 800 thousand years?(kyr). For the period before the Mid-Pleistocene Transition, when global glaciations were less
