Polarization: From better sunglasses to a better way of looking at asteroid surfaces
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth......»»
Workplace tensions: How and when bystanders can make a difference
In today's climate of global political tensions and polarization, workplaces are filled with conflicting viewpoints. When employees hold political identities and perspectives that do not align with their co-workers, they perceive greater incivility f.....»»
After DART smashed into Dimorphous, what happened to the larger asteroid Didymos?
NASA's DART mission (Double Asteroid Redirection Test) slammed into asteroid Dimorphos in September 2022, changing its orbital period. Ground and space-based telescopes turned to watch the event unfold, not only to study what happened to the asteroid.....»»
Interacting polarons: Physicists simulate interacting quasiparticles in ultracold quantum gas
An electron moving through a solid generates a polarization in its environment due to its electric charge. In his theoretical considerations, the Russian physicist Lev Landau extended the description of such particles by their interaction with the en.....»»
Investigating the effects of surface treatment on the antibacterial activity of wood
Research indicates that several pathogenic bacteria can remain contagious on a range of surfaces from hours to days and weeks. While wood as a surface material is known for its antibacterial properties, dry contamination via hands has so far been poo.....»»
NASA"s OSIRIS-REx mission surpasses goal for collection of asteroid samples
The curation team processing NASA's asteroid Bennu sample has removed and collected 2.48 ounces (70.3 grams) of rocks and dust from the sampler hardware—surpassing the agency's goal of bringing at least 60 grams to Earth......»»
Space rocks and asteroid dust are pricey, but these aren"t the most expensive materials used in science
After a journey of seven years and nearly 4 billion miles, NASA's OSIRIS-REx spacecraft landed gently in the Utah desert on the morning of Sept. 24, 2023, with a precious payload. The spacecraft brought back a sample from the asteroid Bennu......»»
Hera asteroid mission goes on trial
At some point, statistically speaking, a large asteroid will impact Earth. Whether that's tomorrow, in 10 years, or a problem for our ancestors, ESA is getting prepared......»»
How could a piece of the moon become a near-Earth asteroid? Researchers have an answer
A team of astronomers has found a new clue that a recently discovered near-Earth asteroid, Kamo'oalewa, might be a chunk of the moon. They hypothesized that the asteroid was ejected from the lunar surface during a meteorite strike—and they found th.....»»

NASA’s Lucy spacecraft will soon make its first flyby of an asteroid
The Lucy spacecraft is on its way to the orbit of Jupiter to study the Trojan asteroids there. But first it will make a flyby of an asteroid called Dinkinesh......»»
NASA mission collected at least 70 grams of material from asteroid Bennu

Things Are Looking Up for Asteroid Mining
Asteroids are rich with the metals used in clean energy technologies. As demand soars, advocates argue that mining them in space might be better than mining them on Earth......»»
NASA"s Lucy spacecraft preparing for its first asteroid flyby
NASA's Lucy spacecraft is preparing for its first close-up look at an asteroid. On Nov. 1, it will fly by asteroid Dinkinesh and test its instruments in preparation for visits in the next decade to multiple Trojan asteroids that circle the sun in the.....»»
NASA"s Psyche asteroid mission: A 3.6 billion kilometer "journey to the center of the Earth"
Psyche was the Greek goddess of the soul, born a mere mortal and later married to Eros, the God of love. Who knows why the Italian astronomer Annibale de Gasparis gave her name to a celestial object he observed one night in 1852?.....»»
NASA"s Lucy spacecraft continues approach to asteroid Dinkinesh
Since NASA's Lucy spacecraft first imaged the asteroid Dinkinesh on Sept. 3, 2023, Lucy has traveled over 33 million miles (54 million km) and is now 4.7 million miles (7.6 million km) away from the small asteroid. However, as Dinkinesh continues on.....»»
Magnetic Minerals May Have Given Life Its Molecular Asymmetry
The preferred “handedness” of biomolecules could have emerged from interactions between electrons and magnetic surfaces on primordial Earth, new research suggests......»»
Osiris-Rex: NASA reveals evidence of water and carbon in sample delivered to Earth from an asteroid
On September 24 this year, a NASA capsule parachuted down to Earth carrying a precious cache of material grabbed from an asteroid. The space agency has now revealed images and a preliminary analysis of the space rocks it found after lifting the lid o.....»»
NASA journeys to the metal-rich asteroid Psyche
It's a world like no other: a metal-rich asteroid that could be the remnants of a small planet, or perhaps an entirely new type of celestial body unknown to science......»»
NASA’s Psyche Mission Is Off to Test a Space Laser (for Communications)
The Psyche probe is heading to its namesake metal-rich asteroid. Along the way, it will demonstrate a near-infrared laser system to send high-rate data hundreds of millions of miles home......»»
