‘Levitating’ nanoparticles could push the limits of quantum entanglement

Particles of glass suspended in laser beams can be made to interact (artist’s impression).Credit: Equinox Graphics Ltd. Physicists have suspended tiny glass spheres in a vacuum and made them interact with one another at close distance. The ‘levitating’ nanoparticles have now been manipulated with enough precision to open new ways of probing the enigmatic twilight …

Astronomers Detect First Clear Signal of Carbon Dioxide in an Exoplanet’s Atmosphere

An early – and exciting – science result from the James Webb Space Telescope (JWST) was announced today: the first unambiguous detection of carbon dioxide in the atmosphere of an exoplanet. This is the first detailed evidence for carbon dioxide ever detected in a planet outside our Solar System. The planet is named WASP-39b and …

What time is NASA’s Artemis 1 SLS megarocket launch to the moon?

CAPE CANAVERAL, Fla — NASA’s Artemis 1 mission will open a new era of U.S. space exploration when it launches to the moon this month, but exactly when it lifts off depends on several factors.  Artemis 1, the first uncrewed test flight of NASA’s Artemis program to return astronauts to the moon, is currently scheduled …

SpaceX, NASA announce date for next Crew Dragon astronaut launch

SpaceX and NASA have settled on October 3rd for the company’s fifth operational astronaut launch, a mission that will also mark the first time a Russian cosmonaut flies on Crew Dragon. Initially scheduled to launch in early September, NASA announced in July that SpaceX’s Crew-5 launch was slipping to late September after the company accidentally …

‘Star factory’ at Milky Way’s heart seen for the first time

Astronomers have reconstructed the history of star formation at the center of the Milky Way for the first time, finding that starbirth radiated outwards from the galaxy’s heart.  The results also revealed that most young stars in the densely packed galactic center formed with only loose associations and drifted further apart over the course of …

7 million years ago, our earliest relatives took their first steps on 2 feet

The oldest known human-like species likely walked on two legs as far back as 7 million years ago, a new study finds, and the discovery sheds light on what first set humans apart from our ape relatives. Researchers analyzed a thigh bone (femur) and a pair of forearm bones (ulnae) from Sahelanthropus tchadensis, which may …

Meet Commander Moonikin Campos, the mannequin going farther than any astronaut

Turn to CNN for live coverage from Kennedy Space Center in Florida, starting on Saturday morning and running through the Monday morning launch. Space correspondents Kristin Fisher and Rachel Crane will bring us moment-by-moment reporting from the launch, along with a team of experts. Rather than astronauts, a mannequin named Commander Moonikin Campos will helm …

synthetic mouse embryo pictured next to natural embryo

Lab-made mouse embryos grew brains and beating hearts, just like the real thing

Scientists coaxed mouse stem cells to grow into synthetic embryos that began developing hearts and brains, just like the real thing. The lab-made embryos, crafted without any eggs or sperm and incubated in a device that resembles a fast-spinning Ferris wheel full of tiny glass vials, survived for 8.5 days. That’s nearly half the length …
