Apophis: The Asteroid Coming Closer Than Satellites

Apophis: The Asteroid Coming Closer Than Satellites

On April 13, 2029, asteroid Apophis will make an extremely close pass by Earth — closer than some satellites. NASA says Apophis will not hit Earth, but this rare flyby gives scientists a once-in-a-lifetime chance to study how Earth’s gravity can affect a massive asteroid. Could it change Apophis’ spin, shift its surface, or help us prepare for a future asteroid threat? In this episode of The Cosmic Brief, we break down why Apophis once worried scientists, what will happen during the 2029 flyby, and why this close encounter matters for the future of planetary defense. The Cosmic Brief explores space mysteries, cosmic events, strange worlds, and the biggest questions in the universe — one brief episode at a time.

Almost Stranded on the Moon: The Apollo 11 Close Call

During the historic Apollo 11 mission, a small failure nearly left astronauts stranded on the Moon. In this episode of The Cosmic Brief, we explore the tense moments inside the Eagle, the isolation of being hundreds of thousands of miles from Earth, and the unexpected solution that helped them make it home. A story of precision, pressure, and how one overlooked detail almost changed history.

What If the Moon Disappeared for 24 Hours?

For one full day, the Moon disappears. No warning. No explanation. At first, the sky just looks darker… but beneath the surface, the effects begin to build. Tides fall out of rhythm. Ocean currents shift. Subtle changes ripple across the planet as Earth briefly operates without one of its most important forces. From the beaches of Florida to the waters of New York Harbor, we explore what would actually happen if the Moon vanished for 24 hours—and why even a short absence would matter more than you think. This is The Cosmic Brief.

The Mystery Object Orbiting Earth

High above Earth, a strange flickering object was spotted moving through the night sky at incredible speed. Amateur astronomers tracked it. Theories spread. Some believed it was space debris. Others weren’t so sure. In this episode, we follow the story of one of the most unusual objects recently seen in low Earth orbit—and how something so small became such a compelling mystery. For a brief moment, it was something anyone could see… if they knew where to look. And that… is a Cosmic Mystery.
