Asteroid Ryugu Holds Life's Code

☄️ Ryugu asteroid yields life's blocks

🇨🇦 Canada's spaceport gets $200M

🛰️ Hera mission targets asteroid

🌌 Rare second-generation star found

🔭 Nearby galaxy undergoes transformation

JAXA (Japan Aerospace Exploration Agency) scientists analyzed samples from asteroid Ryugu, finding all five canonical nucleobases which are the fundamental building blocks for life, returned by the Hayabusa2 mission.

The team identified purines (adenine, guanine) and pyrimidines (cytosine, thymine, uracil) within the samples, noting nearly equal amounts of each type, a composition distinct from previously studied carbonaceous chondrite meteorites.

The study's authors suggest this discovery strengthens the theory that extraterrestrial materials delivered the necessary organic molecules for life to begin on early Earth, providing a complete inventory of prebiotic compounds.

The Government of Canada, through its Atlantic Canada Opportunities Agency (ACOA), is investing a historic $200 million to transform a Nova Scotia spaceport into a cornerstone of the nation's defence capabilities.

The funding will support critical infrastructure development, enhance operational capabilities for national security missions, and facilitate the launch of both commercial and government payloads from the Canso, Nova Scotia launch site.

This investment positions Canada to achieve sovereign launch capabilities, reducing reliance on foreign partners for critical defence and satellite deployments, according to government officials, and will also boost the regional Atlantic economy.

The European Space Agency (ESA) confirmed its Hera spacecraft is on course for the Didymos binary asteroid system, the only celestial body whose orbit has been deliberately altered by human action.

Following a successful deep-space manoeuvre, Hera will rendezvous with the 780-meter asteroid Didymos and its 160-meter moonlet Dimorphos, which was impacted by NASA’s DART (Double Asteroid Redirection Test) spacecraft.

Hera will provide a detailed post-impact survey, measuring Dimorphos’s mass and crater properties, which ESA scientists state is crucial for validating kinetic impactor models as a viable planetary defense strategy.

Astronomers using data from NSF’s NOIRLab have discovered a rare star in the Pictor II dwarf galaxy that preserves the chemical signature of the universe’s very first generation of stars.

The star, PicII-503, exhibits an extreme iron deficiency at less than 1/40,000th of the Sun’s iron content, but also shows a significant overabundance of carbon, a key chemical marker.

Researchers believe PicII-503 provides the missing link connecting carbon-enhanced stars in the Milky Way's halo to an origin in ancient dwarf galaxies that were later absorbed by our own.

University of Arizona astronomers are witnessing the Small Magellanic Cloud (SMC), a nearby dwarf galaxy, undergoing a dramatic transformation as it interacts with its larger galactic neighbors, the Milky Way and LMC.

Using data from ESA's Herschel mission and the Planck observatory, the team observed vast outflows of hydrogen gas being stripped from the SMC, disrupting its star formation and overall galactic structure.

The study provides a real-time example of galactic evolution, showing how gravitational interactions can dismantle smaller galaxies, with astronomers predicting the SMC will eventually be fully absorbed by the Milky Way.
