Extraterrestrial News & Deep Space Exploration
The Milky Way, our cosmic home, is not a static entity. It's hurtling through space at roughly 600 km/s relative to the cosmic microwave background. But beyond this rapid motion, intriguing observations have led astronomers to speculate about another dynamic behavior: the "flapping" of its spiral arms. The Galactic Motion The Milky Way is part...

When it comes to long-term human space exploration, radiation is one of the biggest threats we face. Outside Earth's protective atmosphere and magnetic field, astronauts are exposed to dangerous levels of cosmic radiation and solar energetic particles. This raises an intriguing question: could we build an artificial magnetic field on spacecraft to mimic Earth’s protective... Continue Reading →
Imagine floating above Earth, stars twinkling beyond your visor, and suddenly—you’re thirsty. But you're in a spacesuit. In the vacuum of space. So… how do you take a sip? Is drinking in open space even possible? Let’s dive into this wonderfully weird question. First, What Is Open Space? “Open space” means the environment outside the... Continue Reading →
We take showers for granted here on Earth, where gravity obediently pulls water downward and drains whisk it away. But what happens when you leave gravity behind? Can astronauts take showers in space? Could they even climb into a water-filled rubber bath like on Earth? The answers are both fascinating and a little weird. Hygiene... Continue Reading →
It might sound like science fiction, but it’s happening right now: Earth is slowly losing its atmosphere to space, and the escape is led by the universe’s lightest element—hydrogen. This invisible leak is ongoing, unstoppable, and could eventually reshape the fate of our planet. At Cosmic Watchers, we explore these slow cosmic events that most... Continue Reading →
Imagine waking up on a planet that’s no longer in the same neighborhood of the solar system. Earth is now the fourth planet from the Sun, and Mars has taken Earth’s current place as the third. This planetary swap might sound like science fiction, but it opens up fascinating possibilities—and terrifying consequences. Let’s explore what... Continue Reading →
By Cosmic Watchers When we look up at the night sky, most of the stars we see are many light-years away. But just 4.37 light-years from Earth lies Alpha Centauri, the closest star system to our solar system—and one of the most intriguing prospects for interstellar exploration. The Triple-Star System Alpha Centauri is not a... Continue Reading →
For decades, science fiction has imagined humanity sailing between the stars. From warp drives to wormholes, these fantastical concepts captured the imagination. But today, space agencies and private companies are turning dreams into blueprints. The big question remains: how close are we, really, to interstellar space travel? The Challenges of Getting There Let’s start with... Continue Reading →
When it comes to planets that dominate human imagination, few rival the legendary duo: Earth, our home sweet home, and Mars, the rusty red neighbor that’s been tempting astronauts and sci-fi writers alike for decades. But how do these two stack up side by side? Let’s pit them against each other in a friendly interplanetary... Continue Reading →
By Cosmic Watchers Introduction We often gaze up at the stars, wondering if someone out there is looking back. But what if they already are—not from afar, but as part of a carefully monitored experiment? The Galactic Zoo Hypothesis suggests that alien civilizations might already know we exist… and are intentionally avoiding contact. So what... Continue Reading →
