Large and complex sunspot groups characterize the surface of the dynamic sun during its activity cycle. A new camera system at the Vacuum Tower Telescope (VTT) at the Observatorio del Teide on Tenerife uses image restoration methods to capture small structures in active areas.
Understanding Jupiter’s early evolution helps illuminate the broader story of how our solar system developed its distinct structure. Jupiter’s gravity, often called the “architect” of our solar system, played a critical role in shaping the orbital paths of other planets and sculpting the disk of gas and dust from which they formed.
This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the galaxy was 5.5 billion light-years away and began its trek to us through expanding space).
My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo streamed to my tablet. It sparkled on the screen in front of us.
The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences many other processes in nature.
Researchers at the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory, depend on the facility’s bright, stable electron beam to carry out groundbreaking experiments. Behind the scenes, a dedicated team of physicists, engineers, designers, and technicians in the facility’s accelerator complex are not only maintaining this system for reliable operation but also looking into ways to improve performance and unlock new areas of synchrotron science for the light source’s research community.

The $5 million settlement resolves a civil suit despite DOJ and Capitol Police findings that a U.S. Capitol Police officer acted lawfully in the fatal shooting of Ashli Babbitt
Palm Beach County Deputy Ignacio Diaz, Cpl. Luis Paez and Deputy Ralph Waller were killed when an SUV struck their motorcycles while they were stopped on the roadside
Benjamin Ritchie was executed by lethal injection for fatally shooting Beech Grove Officer Bill Toney during a 2000 foot pursuit, Indiana’s second execution in 15 years.
The satellite population in low Earth orbit (LEO) is not an open book. While data on many satellites is public, others are shrouded in secrecy, and information is incomplete for others. New research shows how observers can determine satellite shapes by watching them occult background stars.
Transistors are the fundamental building blocks behind today’s electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But imagine a parallel world, where we could apply the same level of control and sophistication—not to electricity, but to heat.
The new law dissolves citizen review panels in at least six Iowa cities, with lawmakers citing a need to protect officers from political scrutiny
Tracking exoplanets via orbital mechanics isn’t easy. Plenty of variables could affect how a planet moves around its star, and determining which ones affect any given exoplanet requires a lot of data and a lot of modeling.
Using various ground-based and space telescopes, an international team of astronomers has observed a highly variable young star known as DR Tauri. Results of the observational campaign, published May 12 on the arXiv preprint server, provide crucial information regarding the short- and long-term variability of this star.
