Every planet in our solar system is essentially round. But out in the universe, are there any planets that aren’t spherical? Technically, planets are round, by definition; they need to have enough mass to produce the gravity required to pull themselves into a spherical shape. “Actually, one of the specifications for being a planet is, … Read more
A nuclear bomb could save Earth from a catastrophic asteroid impact, according to a first-of-its-kind lab study. The new experiment, conducted using the world’s most powerful laboratory radiation source, demonstrated that detonating a coordinated nuclear strike close to an asteroid would produce enough force to deflect it from a fatal collision with our planet. Yet … Read more
We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work. But what … Read more
Earth may have had a giant ring of space rocks surrounding it, similar to those around Saturn, which could have led to chaotic meteorite strikes on our planet’s surface, new research suggests. The hypothesized ring may have formed roughly 466 million years ago and was the remains of a gigantic asteroid tugged apart by Earth’s … Read more
Believe it or not, debris from Mars has frequently made its way to Earth after powerful impacts hit the Red Planet’s surface and launch it into space. There have been at least 10 of these meteorite-forming events in Mars’ recent history. When these massive impacts occur, meteorites can be flung away from the Red Planet … Read more
Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature. On August 23 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which … Read more
Earth’s days once got more than two hours longer, thanks to the moon drifting thousands of miles farther away in its orbit over two periods, researchers have discovered. The extra hours of sunlight, in turn, may have led to oxygenation events that ushered in a period when life’s complexity exploded, the study researchers say. “Daylength … Read more
The space rock that wiped out the dinosaurs 66 million years ago was a rare strike from an asteroid beyond Jupiter, a new study details. The finding pins down the nature of the fateful space rock and its origin within our solar system, and may benefit technology that forecasts asteroid strikes on our planet. Most … Read more
Scientists using the James Webb Space Telescope (JWST) have identified a component of water on the mysterious metal-rich asteroid Psyche. The findings suggest the hydration exists as rust and may shed light on how this enigmatic object formed. The asteroid 16 Psyche is pretty unusual for the main asteroid belt between Mars and Jupiter. Measuring … Read more
Mars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be … Read more
