From space hotels and artificial meteor showers, to a new giant mirror that reflects sunlight to Earth — low-Earth orbit is getting weird.

How prepared are we for a solar storm, bad software update or cybersecurity event that could trigger widespread loss of satellite control?
L’essor des mégaconstellations promet une révolution technologique – mais aussi une transformation irréversible du ciel nocturne.
If SpaceX launches one million new satellites, it will increase atmospheric pollution and risk of falling debris. And we will see more satellites than stars.
Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.
Os impactos culturais, espirituais e, principalmente, ambientais não são levados em consideração nos projetos de lançamento de milhares de satélites.
Cultural, spiritual, and most environmental impacts aren’t taken into account when launching thousands of satellites.
As the number of satellites and rocket launches increases, so does the amount of discarded rockets and components. This space junk risks falling to Earth, as it did in Saskatchewan this spring.
The sky is becoming more cluttered with satellites and space junk. This is affecting astronomical study, but will only have a minor effect — if any — on the viewing of the solar eclipse.
Megaconstellations of satellites are hindering the most powerful tool for space exploration: telescopes.
A curious kid asks: Mengapa penting jika Pluto adalah planet atau planet kerdil?
A curious kid asks: Why does it matter if Pluto is a planet or a dwarf planet?
Les mégaconstellations de satellites encombreront visuellement le ciel nocturne, perturbant la recherche astronomique. Et les dommages environnementaux causés par ces satellites sont encore inconnus.
Megaconstellations of satellites will visually clutter the night sky, disrupting astronomical research. And the environmental damage caused by these satellites is still unknown.
A curious kid asks: Why are the northern lights only spotted at areas around the poles?
As thousands of new satellites enter Low Earth Orbit, it’s important to consider their potential impact, including possible environmental damage in addition to hindering the work of astronomers.
Des données accessibles au public et une bonne collaboration entre scientifiques ont conduit à la découverte d’une planète dans un système à trois étoiles.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.
Les satellites de SpaceX vont peupler le ciel nocturne, ce qui aura une incidence sur notre façon d’observer les étoiles. Et ce n’est que le début des mégaconstellations de satellites privés.
SpaceX’s satellites will populate the night sky, affecting how we observe the stars. And this is just the beginning of private satellite mega-constellations.
Selama 76 tahun Pluto dianggap sebagai planet kesembilan. Sejak 2006 disebut planet kerdil.
In the search for the hypothetical Planet Nine, scientists may have uncovered another explanation for the patterns in the orbits of Kuiper Belt objects.
