For years the scientific consensus was that a supermassive black hole (SMBH) resides in the center of the Milky Way. There's plenty of evidence that the SMBH, named Sagittarius A-star, sits in the Galactic Center (GC). But there were still lingering doubts.

In this period of heightened geopolitical flux, enthusiasm for advances in planetary exploration can be dampened. But that's not stopping NASA from forging ahead in its efforts.

Origami and space exploration might not seem like they have much in common, but the traditional paper-folding technique solves one massive problem for space exploration missions - volume. Satellites and probes that launch in rocket housings are constrained by very restrictive requirements about their physical size, and options for assembling larger structures in orbit are limited to say the least. Anything that can fold up like an origami structure and then expand out to reach a fully functional size is welcome in the space community, and a new paper published in Communications Engineering by Xin Ning of the University of Illinois Urbana-Champaign (UIUC) and his lab describes a novel use case for the idea - electromagnetic waveguides.

A major theme in communist governments is the idea of central planning. Every five years, the central authorities in communist countries lay out their goals for the country over the course of the next five years, which can range from limiting infant mortality to increasing agricultural yield. China, the largest current polity ruled by communists, recently released its fifteenth five-year plan, which lays out its priorities for 2026-2030. This one, accompanied by a press release of the China Aerospace Science and Technology Corporation (CASC), the country’s state-owned giant aerospace corporation, has plenty of ambitious goals for its space sector.

The Aurora Borealis and Australis have dazzled and inspired all those who have beheld them since time immemorial. Much like the Moon, stars, constellations, and planets, they are considered a permanent part of our shared cultural heritage. These awe-inspiring displays of light are the result of charged particles from our Sun interacting with Earth's magnetic field. However, there remain unanswered questions about the mechanisms that power aurorae that scientists have been hoping to resolve for decades. For example, there's the question of what powers the electrical fields that accelerate these particles.
