International team develops a new method to determine the origin of stardust in meteorites.

Analysis of meteorite content has been crucial in advancing our knowledge of the origin and evolution of our solar system. Some meteorites also contain grains of stardust. These grains predate the formation of our solar system and are now providing important insights into how the elements in the universe formed.

Working in collaboration with an international team, nuclear physicists at the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory have made a key discovery related to the analysis of “presolar grains” found in some meteorites. This discovery has shed light on the nature of stellar explosions and the origin of chemical elements. It has also provided a new method for astronomical research.

U.S. and U.K. defense agencies plan to award $1 million to startups at the first International Space Pitch Day in November during the Defence Space Conference in London.

The rapid pace of space technology development around the world is prompting military organizations to look beyond national borders to find promising technology. The Techstars Allied Space Accelerator established in 2019, for example, received funding from the U.S. Air Force, Netherlands Ministry of Defence, Norwegian Ministry of Defence and Norwegian Space Agency support.

NASA’s Perseverance Mars rover launched from Cape Canaveral, Florida, on 30 July, carrying a host of cutting-edge technology including high-definition video equipment and the first interplanetary helicopter.

Many of the tools are designed as experimental steps toward human exploration of the red planet. Crucially, Perseverance is equipped with a device called the Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE: an attempt to produce oxygen on a planet where it makes up less than 0.2 percent of the atmosphere.

Oxygen is a cumbersome payload on space missions. It takes up a lot of room, and it’s very unlikely that astronauts could bring enough of it to Mars for humans to breathe there, let alone to fuel spaceships for the long journey home.

NASA researchers have observed “superbolts” of lightning in Jupiter’s atmosphere, which form in clouds made of water and ammonia.

Scientists have discovered what they believe may be the largest impact crater in the entire solar system, with scars covering a vast portion of Jupiter’s huge moon, Ganymede.

Scientists can use some pretty wild forces to manipulate materials. There’s acoustic tweezers, which use the force of acoustic radiation to control tiny objects. Optical tweezers made of lasers exploit the force of light. Not content with that, now physicists have made a device to manipulate materials using the force of… nothingness.

OK, that may be a bit simplistic. When we say nothingness, we’re really referring to the attractive force that arises between two surfaces in a vacuum, known as the Casimir force. The new research has provided not just a way to use it for no-contact object manipulation, but also to measure it.

The implications span multiple fields, from chemistry and gravitational wave astronomy all the way down to something as fundamental and ubiquitous as metrology — the science of measurement.

Most FRBs originate hundreds of millions of light-years away. This one came from inside the Milky Way.
