In July 2025, astronomers detected a fast, bright object racing through the solar system. Now confirmed as 3I/ATLAS, this massive body is only the third known interstellar object ever observed, following ʻOumuamua and 2I/Borisov. But it’s nothing like them.

At 20 km wide, 3I/ATLAS is the largest and most luminous of its kind, and it’s already showing signs of comet-like activity. Detected early, while still far from the Sun, this visitor gives scientists an unprecedented opportunity to observe an alien object for months.

What can it teach us about other planetary systems? Where did it come from? And what else might be out there?

Watch this short for everything you need to know about one of 2025’s most exciting space discoveries.

PODTUBE is a personal project and was originally developed to be used only by its creator, but then the creator decided to open it, making PODTUBE available to everybody with similar needs, for free.

However, PODTUBE has server, bandwidth, development, maintenance and improvement costs.

And the number of users is growing daily, requiring frequent service upgrades to keep a minimum usability level.

Its continuity as a free service depends on your support.

A new peer-reviewed study says tachyons—faster-than-light particles once thought impossible—might fit within Einstein’s special relativity. Using a quantum framework that respects causality, scientists show how these strange particles could reshape how we understand time.

In November 2026, NASA’s Voyager 1 will become the first human-made object to reach a distance of one light-day from Earth, 25.9 billion kilometers away. Here’s what that means for space, time, and communication.

Could Earth be located in the center of a cosmic void? New research suggests that our Milky Way might be sitting in a giant space, potentially solving the mystery of the Hubble tension. Scientists have discovered that the Hubble constant—the rate at which the universe expands—differs when measured locally versus from the early universe. The local void hypothesis proposes that this discrepancy could be explained by our position in a massive underdense region of space. This exciting discovery could change the way we understand the universe’s expansion and even its age. Join us as we dive into this fascinating theory and explore its implications for cosmology

The James Webb Space Telescope has spotted one of the rarest cosmic structures ever seen—two colliding ring galaxies forming what astronomers now call the “Cosmic Owl.” With help from ALMA and the VLA, scientists found active black holes, a radio jet, and a burst of star formation—all happening 11 billion light-years away. Here's how it could reshape our understanding of galactic evolution.
