It’s a familiar annual question, that we’re already hearing as we enter into June. “What are those two bright objects in the west?” They’re none other than the two brightest planets in the sky, Jupiter and Venus. Keep an eye on the dusk sky over the next week, and you’ll see the two worlds getting ever closer to each other in the west. Though this happens every year or so, an evening conjunction assures that lots of the general public will see one of the best planetary pairings of 2026.
In our final installment in the series, we'll examine all the close calls, possible candidates, and instances in which extraterrestrial signals could not be ruled out
A multi-year survey of millions of stars in the Small Magellanic Cloud shows that the dwarf galaxy is expanding rather than rotating. This is due to the influence of its larger neighbour, the Large Magellanic Cloud.
Jeff Bezos' Blue Origin is assessing damage to its launch pad after a rocket exploded during a test firing, creating a giant orange fireball seen and felt for miles around.
Galactic collisions are events of breathtaking proportions. The Supermassive Black Holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, they could eventually get “kicked” out of the center of their galaxy - and finding these “recoiling” black holes has been a challenge of cosmology for decades. A new paper, available on arXiv by an international team, used a novel idea to track down these fast-moving behemoths.
The prototype ngVLA antenna tested its systems by observing and tracking the Crab Nebula, also known as Taurus A (3C144), the remnant of an exploded star.
It might not seem like it, but the Moon is constantly being both sandblasted and baked. Its lack of a thick atmosphere allows micrometeorites to impact the surface at speed, and the solar wind isn’t held back either, baking the regolith with a constant flow of high-energy particles. These processes drive what is called “space weathering”, and it can drastically alter the physical and chemical properties of the lunar dirt over the course of billions of years. And we’re finally getting a better sense of what that means in practice thanks to two new papers from researchers at the Chinese Academy of Sciences and Peking University, which used advanced electron tomography and spectroscopic techniques to analyze samples returned from the Chang’e-5 mission to the near side of the Moon.
