What Yang Liwei heard during China’s first crewed spaceflight still defies physics, sensors, and every known explanation.

As the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also ...

The startup secures $2 million in pre-seed funding to ramp up testing and launch its first demonstration satellite next year.

Today, we're going to show you some of the most mind-blowing and scariest interstellar sounds, including what Earth sounds like. But wait a minute, there IS no sound in space. So, where does this ...

Dec. 19 (UPI) --Comet 3I/ATLAS passed its nearest point to Earth early Friday and approaching within 168 million miles. After its brief visit Friday the interstellar object 3I/ATLAS will head back ...

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more ...

There are about 15,000 satellites orbiting Earth. Most of them, like the International Space Station and the Hubble Telescope, reside in low Earth orbit, or LEO, which tops out at about 1,200 miles (2 ...

A stray comet from another star swings past Earth this week in one last hurrah before racing back toward interstellar space. Discovered over the summer, the comet known as 3I/Atlas will pass within ...

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 ...

NASA is monitoring an asteroid—"2025 XM"—that is expected to pass within 295,000 miles of Earth today, December 9, according to data from the agency’s Jet Propulsion Laboratory (JPL). The visiting ...

SQUIRE aims to detect exotic spin-dependent interactions using quantum sensors deployed in space, where speed and environmental conditions vastly improve sensitivity. Orbiting sensors tap into Earth’s ...
