Mirrors in Space? The FCC Just Approved a Sun-Reflecting Satellite, and Astronomers Are Worried - CNET

• Astronomers have confirmed the presence of an atmosphere on LHS 1140 b, a rocky exoplanet located 48 light-years from Earth. • The planet is situated within its star's habitable zone, making it a primary candidate for studying the potential for liquid water and life.

• A report from the National Academies confirms the rapid advancement of climate change attribution science, which identifies the specific role of global warming in severe weather events. • Experts like Davide Faranda of France’s National Center for Scientific Research emphasize that evaluating "loss and damage" is now the primary objective for the field.

• Scientists have detected sugar in interstellar space for the first time, marking a significant breakthrough in astronomical chemistry. • The discovery was made using broadband spectroscopic surveys from the 40-meter Yebes radio telescope and the 30-meter IRAM telescope.

• NASA's Curiosity rover has discovered an unusual honeycomb-like texture on the Martian surface. • The findings include these strange geometric patterns alongside various dark rocks scattered across the area.

• Astronomers have detected glycolaldehyde, a type of sugar commonly found in raspberries, within interstellar space. • The discovery proves that complex organic molecules, such as sugars, can form naturally in the harsh environment of space without the need for a planetary surface.

• Physicists have developed a new quantum theory that resolves a decades-old conflict between two rival models regarding how impurities behave within many-particle systems. • In a separate breakthrough, researchers at Stanford University are utilizing "twisted light" to enable quantum computing operations without the need for extreme cooling.

• Scientists have solved a 150-year-old mystery regarding gallium by discovering that its unusual atomic bonds re-form at high temperatures. • This discovery contradicts decades of accepted scientific theory and fundamentally rewrites the understanding of the element's chemical behavior.

• Astronauts on the private Fram2 Crew Dragon mission successfully performed the first-ever medical X-rays in orbit in 2025. • The mission utilized a new portable X-ray device capable of diagnosing medical issues like broken bones, as well as identifying damage to satellites and spacesuits.

• The Trump administration has appointed Matthew M. Wielicki to oversee the National Climate Assessment, a major federal report on global warming. • Dr. Wielicki has previously criticized the scientific consensus on climate change, labeling current perspectives as "alarmist."

• Astronomers have detected sugar molecules floating in deep space for the first time, marking a significant discovery in astrochemistry. • These sweet molecules are believed to be precursors to the complex organic compounds necessary for the development of life.

• The Eärendil-1 space mirror has been cleared for launch, marking the first step toward a massive proposed constellation of 50,000 satellites. • The system is designed to reflect sunlight, though the project has sparked significant concerns regarding increased light pollution and its impact on astronomy.
