3I/ATLAS's Coma Proves Another Cometary Formation Theory

Interstellar visitor 3I/ATLAS has been constantly changing as it makes its way through our solar system. That’s to be expected, as, for the first time in potentially billions of years, it's getting close to the energy put out by a star. Scientists have been keeping a close watch on those changes, both to ensure there’s nothing unexplainable by our current understanding, but also to compare 3I/ATLAS to both previous interstellar visitors as well as comets in our own solar system. A recent paper from European researchers describes how the changes in a particular material ratio in 3I/ATLAS’ coma fit with our current understanding of cometary geology.

Black Holes Have No Hair, But They Do Have Comb Overs

Making a black hole is easy. Just squeeze a bunch of stuff into a small enough volume. It doesn't even matter what you use. You can collapse stars, planets, old car tires, Labubus, or missing left socks. The resulting black hole will only depend on the mass, rotation, and electric charge of the original material.

Navigating through interference at Jammertest

Satellite navigation is essential to everything from tracking your morning jog to landing air ambulances. But as reliance on satellite navigation grows, so do the risks associated with its interruption, natural or intentional. In its pursuit of strengthening European resilience in navigation, the European Space Agency (ESA) took part in Jammertest.

The exoplanet revolution at 30: 1st alien world was found around a sun-like star three decades ago

The discovery of the "hot Jupiter" exoplanet 51 Pegasi b on Oct. 6, 1995 changed the course of astronomical history.

New Research Suggests Red Dwarf Systems are Unlikely to Have Advanced Civilizations

The Copernican Principle, named in honor of Nicolaus Copernicus (who proposed the heliocentric model of the Universe), states that Earth and humans do not occupy a special or privileged place in the Universe. In cosmological terms, this essentially means that Earth is representative of the norm, and life is likely to exist throughout the cosmos. While our efforts to find extraterrestrial life, a field of study known as astrobiology, have yielded no results so far, these efforts have been limited in scope. As a result, scientists are forced to speculate based on the only planet known to support life—i.e., Earth.

Rogue Planet Found Having Massive "Growth Spurt"

Rogue planets, also known as free-floating planets (FFP) or isolated planetary-mass objects (iPMO), have become a major focus for astronomers. The first such objects were detected in 2000 by teams at the United Kingdom Infrared Telescope (UKIRT) and the Keck Observatory, though earlier detections were made that were unconfirmed at the time. Since then, research has shown that these planets may actually be more common than planets that orbit stars, with some estimates placing the population as high as 4 trillion in our galaxy alone.
