Physicists have discovered a remarkable correspondence between dense states of gluons-the gluelike carriers of the strong nuclear force within atomic nuclei-and enormous black holes in the cosmos. The dense walls of gluons, known as a color glass condensate (CGC), are generated in collisions of atomic nuclei. This CGC measures a mere 10-19 kilometers across-less than a billionth of a kilometer.

China launched a Kuaizhou 1A carrier rocket on Wednesday afternoon at the Jiuquan Satellite Launch Center in the country's northwestern desert, placing four meteorological satellites in orbit, according to China Aerospace Science and Industry Corp. The State-owned company said in a release that the solid-propellant rocket blasted off at 5:09 pm from its launch vehicle and then placed four

Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near

With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they've ever been to finding an analog of Earth's "twin." If they succeed in locating one, it could reveal valuable insights into Earth's future, and our risk of developing a runaway greenhouse climate as Venus did. Scientists who wrote the paper began wit

Monday's planned drive positioned Curiosity with a new workspace to investigate. We have left the Marker Band, with Natalie's blog nicely summarizing our campaign there. As a physicist and spectroscopist by training, I find myself looking more at the analytical data, in particular X-ray fluorescence data, acquired on rocks, than the rocks themselves. But there was something about the primary roc

Human Lander Challenge
Huntsville AL (SPX) Mar 23, 2023 As NASA and industry partners develop new human landing systems to transport astronauts from lunar orbit to the Moon's surface and back as part of Artemis, the agency is asking university students to investigate solutions to one particularly dusty aspect of landing spacecraft on the lunar surface. NASA's new Human Lander Challenge invites college students

The National Reconnaissance Office (NRO) has awarded contracts to BlackSky Technology and Planet Labs Federal for the exploration of commercial hyperspectral image capabilities under the Strategic Commercial Enhancements (SCE) Broad Agency Announcement (BAA) program. BlackSky Technology, a geospatial intelligence solutions provider, has been selected for a multi-stage SCE BAA framework stu

In 2017, a mysterious comet dubbed 'Oumuamua fired the imaginations of scientists and the public alike. It was the first known visitor from outside our solar system, it had no bright coma or dust tail, like most comets, and a peculiar shape - something between a cigar and a pancake - and its small size more befitted an asteroid than a comet. But the fact that it was accelerating away from

Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid's composition from the expelled material. On 26 Septe

The world's first 3D-printed rocket launched successfully on Wednesday, marking a step forward for the California company behind the innovative spacecraft, though it failed to reach orbit. Billed as less costly to produce and fly, the unmanned Terran 1 rocket launched from Cape Canaveral, Florida at 11:25 pm (0325 GMT Thursday) but suffered an "anomaly" during second-stage separation as it
