Ryugu asteroid origins in the solar nebula decoded by carbonates
Japan's Aerospace Exploration Agency sent the Hayabusa2 spacecraft to 162173 Ryugu in 2019, an asteroid in orbit near Earth that is comprised of rocky fragments originating from a larger parent body. Multiple rovers brought samples from the asteroid'.....»»
NASA Retires Asteroid-Hunting Telescope
NASA’s NEOWISE telescope has searched for asteroids, brown dwarfs and luminous galaxies. The spacecraft will soon burn up in Earth’s atmosphere.....»»

Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»

Born to modulate: Researchers reveal origins of climate-controlling particles
Aerosol particles are tiny. Swirling suspended in the air around us, most are smaller than the smallest bug, thinner than the thinnest hair on your head, gossamer specks practically invisible to the naked eye. Newly formed ones are nano-sized. Yet th.....»»
Scientists discuss why we might not spot solar panel technosignatures
One of NASA's key priorities is understanding the potential for life elsewhere in the universe. NASA has not found any credible evidence of extraterrestrial life—but NASA is exploring the solar system and beyond to help us answer fundamental questi.....»»
Silicon plus perovskite solar reaches 34 percent efficiency
There are still longevity problems, but things continue to get better. Enlarge / Some solar panels, along with a diagram of a perovskite's crystal structure. (credit: Subhakitnibhat Kewiko) As the price of silicon panels.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
How solar panels went from ’50s satellites to your backyard
From Einstein's theories of light to Bell Lab's revelations about doping silicon, solar power has been inching toward its current craze for more than a century. Here's how we got here......»»
Researchers demonstrate mechanism that may have stabilized the first RNA molecules
The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team at ORIGINS, a Munich-based Cluster of Excellence, has demonstrated a mechanism that could have.....»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»

Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
A new study shows how the sun could permanently capture rogue planets
Interest in interstellar objects (ISOs) was ignited in 2017 when 'Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet 2I/Borisov......»»

How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
Mass extinction 66 million years ago triggered rapid evolution of bird genomes, study finds
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began......»»
NASA smacked a spacecraft into an asteroid—and learned details about its 12-million-year history
