Space dust from 4.2bn-year-old asteroid could hold key to preventing cataclysmic collisions with ...

Rubble pile asteroid is almost as old as the solar system, a sign that it can withstand great shocks and may be difficult to destroy, research suggests

Tiny specks of dust from a "giant space cushion" almost as old as the solar system can provide new clues about how to avoid catastrophic asteroid collisions with Earth, research suggests.

Primordial asteroids are like giant space pillows and could be harder to destroy than previously ...

Dust collected from the surface of an ancient, peanut-shaped and "potentially-hazardous" asteroid has revealed that some space rocks are much bouncier and harder to destroy than first thought — posing concerns about Earth’s long-term safety. 

The analysis of three tiny dust particles — gathered from the surface of the 1640-foot-long (500 meters) rubble pile asteroid Itokawa — shows that the cosmic wanderer has survived in space despite numerous collisions for at least 4.2 billion years.

Stunning Photos of Comet with Broken Tail Streaking Through Solar System | PetaPixel

The C/2022 E3 (ZTF), to give the comet its official name, has not had an easy ride through our solar system. Solar storms have disconnected its tail which Claro has expertly illustrated with his incredible images.

“As far as I know, it’s not fixable,” he says to PetaPixel about the comet’s broken tail.

Generac Hid Knowledge of Defective Solar System Part, Suit Says

Generac Holdings Inc. concealed important business metrics from investors, including the health of its legacy generator offerings and a component defect in a solar energy system, an investor says in a proposed class action.

The investor, the California Ironworkers Field Pension Trust, says Generac moved into the solar power and storage business to offset rivals' bites out of its generator sales. But that move depended on a partner that eventually faced bankruptcy.

A Novel Propulsion System Would Hurl Hypervelocity Pellets at a Spacecraft to Speed it up - ...

Today, multiple space agencies are investigating cutting-edge propulsion ideas that will allow for rapid transits to other bodies in the Solar System.

As we explored in a previous article, it would take spacecraft using conventional propulsion anywhere from 19,000 to 81,000 years to reach even the nearest star, Proxima Centauri (4.25 light-years from Earth).

Scientists find 17-pound meteorite in Antarctica | Ideastream Public Media

Antarctica is the world's premier hunting ground for meteorites. One reason is that space rocks stand out against the ice.

MARIA VALDES: Although meteorites fall in a random fashion all over the globe pretty evenly, the probability of finding a meteorite is enhanced if the background is a plain color, like snow or ice or sand in the case of the Sahara or the Atacama.
