The near-Earth asteroid 2025 TF (red crosshairs) came about as close to Earth as the International Space Station on Wednesday (Oct. 1), evading detection until hours later. (Image credit: ESA / Las Cumbres Observatory) A small asteroid zoomed past Earth closer than most satellites last week — and astronomers didn’t notice it until hours later. The surprise asteroid encounter occurred …

Astronomers have spotted something new out in deep space. They’re calling it an “odd radio circle,” or ORC for short, and it’s stranger than anything they expected. Picture a faint, glowing ring of radio waves, larger than almost anything else in the cosmos, quietly sitting around a galaxy billions of light-years away. That’s an ORC, and they just …

Astronomers have spotted a vast wave rolling through the outer disk of our galaxy. It stretches over tens of thousands of light-years and appears to ripple away from the center, like circles spreading from a stone tossed into a pond. The discovery comes from fresh analyses of data gathered by the European Space Agency’s Gaia space telescope, led by a …

ESA/Gaia/DPAC, S. Payne-Wardenaar, E. Poggio et al (2025) The Milky Way galaxy is like a gigantic ocean gyre or eddy that spins and wobbles around its center. But our home galaxy also has a colossal wave rippling through it, pulling and pushing an ocean of stars and cosmic dust in its wake, according to newly released images from the European …

IN A NUTSHELL 🌌 Scientists detect the heartbeat of a newborn magnetar within a gamma-ray burst, revealing new cosmic insights. 🚀 The discovery challenges the belief that gamma-ray bursts are solely powered by black holes. 🔍 Researchers identified a periodic signal that confirms some gamma-ray bursts are driven by newborn magnetars. 🌠 The findings open new avenues for understanding the …

Thirty years ago this week, two Swiss astronomers announced that they had spotted the first known planet orbiting a Sun-like star. The Nobel-winning discovery, later published in the pages of Nature1, was the culmination of centuries of dreaming, and decades of searching, for worlds beyond the Solar System. It was also the start of a whirlwind of discovery. Astronomers have …

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed Planet Y. The planet has not been detected but merely inferred by the tilted orbits of some distant objects in the Kuiper Belt — a large ring …

A huge “wave” is rippling through our galaxy, pushing billions of stars in its wake, a new study reveals. The Milky Way‘s galactic wave was spotted in mapping data from the European Space Agency‘s (ESA) Gaia space telescope, which charted the positions and movement patterns of millions of stars with high accuracy before retiring earlier this year. Like ripples in …

IN A NUTSHELL 🌌 Cosmic channel discovered connecting our solar system to distant stars challenges perceptions of space’s emptiness. 🔭 Advanced X-ray technology like eRosita unveils hidden routes and interstellar structures. 🔥 The Local Hot Bubble, shaped by supernovas, is not the void it seems, containing dynamic processes. 🪐 New findings emphasize the complexity and interconnected nature of our cosmic …
