Asteroid shower on the Earth-Moon system 800 million years ago revealed by lunar craters
A research team led by Osaka University investigated the formation ages of 59 lunar craters with a diameter of approximately 20 km using the Terrain Camera (TC) onboard the lunar orbiter spacecraft Kaguya. Kaguya (formerly SELENE, for SELenological and ENgineering…

SwRI scientists demonstrate speed, precision of in situ planetary dating device
CODEX designed to determine age of rocks on Mars, the Moon without having to return samples
Asteroid impact, not volcanoes, made the Earth uninhabitable for dinosaurs
Modelling of the Chicxulub asteroid impact 66 million years ago shows it created a world largely unsuitable for dinosaurs to live in. The asteroid, which struck the Earth off the coast of Mexico at the end of the Cretaceous era…

Protecting Earth from asteroid impact with a tethered diversion
Our planet exists within the vicinity of thousands of Near-Earth Objects (NEOs), some of which – ?Potentially Hazardous Asteroids (PHAs)? – ?carry the risk of impacting Earth causing major damage to infrastructure and loss of life. Methods to mitigate such a collision are highly desirable.
Protecting Earth from asteroid impact with a tethered diversion
The use of a tether assisted system could prevent an asteroid impacting Earth without the risk of fragmentation
4,000th comet discovered by ESA and NASA Solar Observatory
On June 15, 2020, a citizen scientist spotted a never-before-seen comet in data from the Solar and Heliospheric Observatory, or SOHO — the 4,000th comet discovery in the spacecraft’s 25-year history. The comet is nicknamed SOHO-4000, pending its official designation…

Ancient asteroid impacts created the ingredients of life on Earth and Mars
A new study reveals that asteroid impact sites in the ocean may possess a crucial link in explaining the formation of the essential molecules for life. The study discovered the emergence of amino acids that serve as the building blocks…

Astronomers predict bombardment from asteroids and comets in another planetary system
The planetary system around star HR8799 is remarkably similar to our Solar System. A research team led by astronomers from the University of Groningen and SRON Netherlands Institute for Space Research has used this similarity to model the delivery of…
The asteroids Ryugu and Bennu were formed by the destruction of a large asteroid
What is the origin of the asteroids Bennu and Ryugu, and of their spinning-top shape? An international research team led by Patrick Michel, a CNRS researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d’Azur/Université Côte d’Azur) and Ronald-Louis Ballouz…

Dinosaur-dooming asteroid struck earth at ‘deadliest possible’ angle
The simulations show that the asteroid hit Earth at an angle of about 60 degrees, which maximised the amount of climate-changing gases thrust into the upper atmosphere.

ATLAS telescope discovers first-of-its-kind asteroid
We often think of asteroids and comets as distinct types of small bodies, but astronomers have discovered an increasing number of “crossovers.” These objects initially appear to be asteroids, and later develop activity, such as tails, that are typical of…
