Amino acids found in asteroid samples collected by Japan’s Hayabusa2 probe

More than 20 types of amino acids have been detected in samples Japan’s Hayabusa2 space probe brought to Earth from an asteroid in late 2020, an official said Monday.

The acids discovered are very important substances for living things and could hold clues to understanding the origins of life,

Planetary Defense exercise uses Apophis as Hazardous Asteroid Stand-In

Watching the skies for large asteroids that could pose a hazard to the Earth is a global endeavor. So, to test their operational readiness, the international planetary defense community will sometimes use a real asteroid’s close approach as a mock encounter with a “new” potentially hazardous asteroid. The lessons learned could limit,

Hubble confirms largest comet nucleus ever seen

NASA’s Hubble Space Telescope has determined the size of the largest icy comet nucleus ever seen by astronomers. The estimated diameter is approximately 80 miles across, making it larger than the state of Rhode Island. The nucleus is about 50 times larger than found at the heart of most known comets.

Characteristics of Apophis, the asteroid that will approach Earth in 2029

The study, in which the Universidad Carlos III de Madrid (UC3M) and the Universidad Estatal Paulista Julio de Mesquita Filho (Julio de Mesquita Filho Paulista State University) (UNESP) of Brazil are participating, analyses the surface and dynamics of Apophis, an asteroid that will pass close to Earth in 2029.

The Apophis asteroid was discovered in 2004 and has been monitored since then due to its classification as a potentially hazardous asteroid (PHA),

Ryugu could be a remnant of an extinct comet

Asteroids hold many clues about the formation and evolution of planets and their satellites. Understanding their history can, therefore, reveal much about our solar system. While observations made from a distance using electromagnetic waves and telescopes are useful, analyzing samples retrieved from asteroids can yield much more detail about their characteristics and how they may have formed.

NASA System Predicts Impact of Small Asteroid

Asteroid 2022 EB5 was too small to pose a hazard to Earth, but its discovery marks the fifth time that any asteroid has been observed before impacting into the atmosphere.

A small asteroid hit Earth’s atmosphere over the Norwegian Sea before disintegrating on March 11, 2022. But this event wasn’t a complete surprise: Astronomers knew it was on a collision course,

The state of planetary defense in the 2020s

The Earth exists in a dangerous environment. Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet. Most of these are too small to pose a threat, but some can be cause for concern.

As a scholar who studies space and international security,
