The Sky This Week from January 16 to 23: Caroline’s Rose blooms

Sky This Week is brought to you in part by Celestron. Friday, January 9Cygnus may be sinking toward the horizon a few hours after sunset, but there’s still a bit of time to glimpse some of this constellation’s many treasures. Today let’s try for M39, a loose open cluster in the northeastern reaches of the Continue reading "The Sky This Week from January 16 to 23: Caroline’s Rose blooms" The post The Sky This Week from January 16 to 23: Caroline’s Rose blooms appeared first on Astronomy Magazine .

NASA brings Crew-11 home early in rare medical evacuation

NASA brings Crew-11 home early in rare medical evacuation

SpaceX Crew-11 splashed down safely in the Pacific after more than five months in orbit aboard the International Space Station. The four astronauts completed over 140 experiments and traveled nearly 71 million miles around Earth. NASA brought the crew home earlier than planned due to a medical concern, with officials confirming the affected crew member is stable. The mission underscores how quickly today’s space programs can adapt while keeping astronauts safe.

A deadly chemical frozen in ice may have sparked life on Earth

A deadly chemical frozen in ice may have sparked life on Earth

Hydrogen cyanide, a toxic chemical, may have helped spark the chemistry that led to life. When frozen, it forms crystals with highly reactive surfaces that can drive unusual chemical reactions, even in extreme cold. These reactions could produce more reactive molecules that pave the way for life’s basic ingredients. The findings suggest frozen worlds may be more chemically active than once thought.

Those strange red dots in James Webb images finally have an explanation

Those strange red dots in James Webb images finally have an explanation

For years, strange red dots in James Webb images left scientists puzzled. New research shows they are young black holes hidden inside dense clouds of gas, glowing as they devour their surroundings. These black holes are smaller than expected but grow rapidly, shedding light on how supermassive black holes appeared so early in cosmic history. The finding reveals a violent and messy phase of the universe’s youth.

Fewer offspring, longer life: The hidden rule of mammal aging

Fewer offspring, longer life: The hidden rule of mammal aging

A large international study reveals that mammals tend to live longer when reproduction is suppressed. On average, lifespan increases by about 10 percent, though the reasons differ for males and females. Castrated males avoid the harmful effects of testosterone, while females gain longevity by sidestepping the intense physical demands of pregnancy and nursing. The results underscore a powerful biological trade-off between making offspring and staying alive longer.

Scientists “resurrect” ancient cannabis enzymes with medical promise

Scientists “resurrect” ancient cannabis enzymes with medical promise

Scientists have uncovered how cannabis evolved the ability to make its most famous compounds—THC, CBD, and CBC—by recreating ancient enzymes that existed millions of years ago. These early enzymes were multitaskers, capable of producing several cannabinoids at once, before evolution fine-tuned them into today’s highly specialized forms. By “resurrecting” these long-lost enzymes in the lab, researchers showed how cannabis chemistry became more precise over time—and discovered something unexpected: the ancient versions are often more robust and easier to work with.

Scientists found the soil secret that doubles forest regrowth

Scientists found the soil secret that doubles forest regrowth

New research shows tropical forests can recover twice as fast after deforestation when their soils contain enough nitrogen. Scientists followed forest regrowth across Central America for decades and found that nitrogen plays a decisive role in how quickly trees return. Faster regrowth also means more carbon captured from the atmosphere. The study points to smarter reforestation strategies that work with nature rather than relying on fertilizers.
