Hubble shows 'farting' comet reversing its spin for the first time ever —‬ and it may soon 'self-destruct'

A new analysis of archival Hubble Space Telescope photos reveals that a peculiar comet slowed its spin before fully reversing its rotational direction during a flyby of Earth in 2017.

The #ALMA survey to Resolve exoKuiper belt Substructures (ARKS), has produced the sharpest images ever of 24 debris discs, the dusty belts left after #planets finish forming.

These discs are the cosmic equivalent of the teenage years for planetary systems – somewhat more mature than newborn, planet-forming discs, but not yet settled into adulthood.

Debris discs are representing the collision-dominated phase of the #planet formation process.

With ALMA, astronomers are able to characterise the disc structures pointing to the presence of planets. In parallel, with direct imaging and radial velocity studies, searches for young planets in these systems is possible.

Solar System’s counterpart to this phase is the #Kuiper Belt, a ring of icy debris beyond #Neptune that preserves a record of massive collisions and planetary migrations from billions of years ago.

By studying 24 exoplanetary debris belts, the ARKS team has opened a window into what our Solar System went through as the Moon was forming and as planets jostled for their final places, and sometimes trading orbits.

ALMA Reveals Teenage Years of New Worlds

ARKS survey by ALMA provides insights into the early chaotic phases of planet formation, bridging gaps in our understanding of planetary systems.

Scientific Frontline Jan 20

This research fills a critical "missing link" in #planetary science, offering a comparative lens to understand the history of our own Solar System—specifically the #Kuiper Belt and the Moon's cratering—while helping scientists determine if our system's chaotic evolution is unique or a cosmic norm.

International astronomical survey captures remarkable images of the “teenage years” of new worlds

The growing pains of young planets as they enter their teenage phase have been captured in unprecedented detail

Eutelsat lève 1,5 milliard d’euros et l’État devient le premier actionnaire
https://next.ink/brief_article/eutelsat-leve-15-milliard-deuros-et-letat-devient-le-premier-actionnaire/

« La participation de l’État au capital d’Eutelsat est désormais de 29,65 %, ce qui en fait le premier actionnaire »,

Cette levée de fonds doit permettre le « développement d’Eutelsat dans le domaine des constellations LEO, segment stratégique pour les télécommunications de demain et dont le marché connaît un fort développement ». Un segment où Starlink de SpaceX est déjà en place et sur lequel Amazon Leo (ex-Kuiper) se prépare aussi, au grand dam des syndicats.

#Amazon's satellite 🛰️ constellation currently consists of just over 150 satellites. By 2028, Amazon plans to expand it to over 3000 satellites.
Initially, the service is to be available in five countries: #Germany, #France, #GreatBritain, #Canada, and the #USA
