Plasma-ramming Device Works as A True Speedometer For Spacecraft

Space & Environment, Tech /

Given that satellites orbit at speeds of thousands of miles per hour, it’s crucial to know exactly how fast they’re moving in order to prevent potential collisions. A new instrument, called the Spacecraft Speedometer, promises to significantly improve this kind of measurement. Traditional Tracking Methods and Their Limitations Ground stations typically track satellite speed using […]

A Star has Been Obliterated by a Roaming Supermassive Black hole

Aerospace, Space & Environment /

In 2024, a system designed to detect sudden brightening events discovered something strange. However, the automated system meant to identify the object couldn’t determine what it was observing. Nearly a year later, we know it was the first tidal disruption event—where a star is torn apart by a supermassive black hole—seen in visible light. Unusually,

This Disintegrating Planet Leaves a Destructive Trail Spanning Over 5 Million Miles

Space & Environment /

Astronomers have identified one of the most inhospitable exoplanets ever seen—a tiny world being scorched by its parent star and trailing a massive, comet-like plume of vaporized rock behind it. A Molten Planet with a Vapor Tail While much of exoplanet research focuses on potentially habitable worlds with the right conditions for liquid water, BD+05
