Long before Sputnik, something else was already circling our planet—seen by pilots, tracked by radar, and photographed for decades. If the decoded signals are real, this object has been observing ...

Abstract: We consider the problem of referring camouflaged object detection (Ref-COD), a new task that aims to segment specified camouflaged objects based on a small set of referring images with ...

For months now, astronomers have been closely watching the mysterious interstellar object 3I/ATLAS as it rips through the solar system at a breakneck velocity. And before it finally leaves us for good ...

Here’s what you’ll learn when you read this story: Object Arjuna 2025 PN7 was thought to be a meteorite in an Earthlike orbit, but that is now being questioned. The new hypothesis suggests that 2025 ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

The Manhattan-size interstellar object 3I/ATLAS will buzz past Mars this week — making its closest pass to any planet on its route as scientists are rushing to coordinate craft to observe the ...

Here’s what you’ll learn when you read this story: Object 3I/ATLAS is now too far from Earth to aim a telescope at, but prior observations showed some unusual behavior. The anomalous nature of the ...

Astronomers have detected an unusually powerful and compact object in a nearby galaxy, one so bright and unique that it may represent an entirely new class of cosmic phenomena. The source, named ...

It’s probe-ably nothing. The newly discovered Manhattan-sized interstellar object zooming through our solar system has been identified as a comet — but two Harvard scientists argue there is reason to ...

Earlier this month astronomers were thrilled to discover only the third known interstellar object ever seen in our solar system. Now dubbed 3I/ATLAS, the suspected comet has just zoomed past the orbit ...

Earlier this month, astronomers were thrilled to spot an interstellar object — only the third of its kind ever observed — hurtling toward the center of the solar system on an extremely unusual ...
