Doppler Effect Gravitational Waves Dark Energy Solar Flares (CCTV/CMSA) China's Shenzhou 19 astronauts return to Earth China's three-person Shenzhou 19 mission came home on Wednesday (April 30) after six months in orbit. The Shenzhou 19 spacecraft - carrying astronauts Cai Xuzhe, Song Lingdong and Wang Haoze - undocked from the Tiangong space station on Tuesday (April 29) at 4 p.m. EDT (2000 GMT; 4 a.m. on April 30 China Standard Time), according to Chinese space officials.

Watch now Science & Astronomy (NASA's Goddard Space Flight Center) What can ripples in spacetime reveal about black holes? Cosmic echoes from some of the universe's most violent collisions are far more nuanced than scientists had realized, according to new research. Like the lingering chime of a struck bell, tiny ripples in the fabric of spacetime are created when massive objects like black holes spiral toward each other and merge into a single, larger black hole. These ripples are known as "gravitational waves," and astronomers rely on theoretical models to decode the waves' faint signals, both in the final moments leading up to the merger and in the aftermath.

A United Launch Alliance (ULA) Atlas V rocket lifted off from Florida's Cape Canaveral Space Force Station today (April 28) at 7:01 p.m. EDT (2301 GMT), carrying 27 of Amazon's "Project Kuiper" broadband spacecraft toward low Earth orbit (LEO). It was the first of more than 80 planned launches to build out the Project Kuiper megaconstellation, which will eventually harbor more than 3,200 spacecraft. Read More Space.com Presents: Eclipses!

Earth's moon is currently emerging from its April 27 new moon phase, during which it passed between the sun and Earth, causing its shadow-drenched disk to be temporarily lost from sight in the sun's glare. In the coming days the moon will form a waxing crescent, which will grow steadily larger in the run-up to its first quarter phase, which will happen on Sunday, May 4.

"I was right in the middle of emptying the contents of my stomach onto the steppes of Kazakhstan." The camera didn't show any of this, a fact that sparked some worry among folks watching NASA's landing webcast: Was Pettit all right? Had he been whisked away to a hospital or something? Read More Science & Astronomy (NASA/JPL-Caltech) What happens inside neutron stars? Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the universe. A typical neutron star has a mass a few times the mass of the sun, compressed into a region only a dozen kilometers across. In the outermost layers of neutron stars, the density is billions of times greater than the density of a diamond. In the cores of neutron stars, the crushing pressures can squeeze apart atomic nuclei, and maybe even protons and neutrons themselves.

A Falcon 9 rocket carrying 23 Starlink broadband satellites - including 13 with direct-to-cell capability - lifted off from NASA's Kennedy Space Center in Florida Monday at 10:34 p.m. EDT (0234 GMT on April 29). It was the second Starlink group to fly yesterday; a Falcon 9 lofted 27 of the internet craft from California's Vandenberg Space Force Base earlier in the afternoon.

From the late 1960s almost until the end of the 1990s, a bloody war between communist groups and democracy defenders raged, with a few short breaks, in the jungles and on the rice fields of Cambodia. The conflict left behind a hidden legacy that keeps increasing the war's death toll to this day.
