Scientists Intrigued by Mysterious Object Floating Near Earth

Earth has a new friend — and it's been waiting for us to notice it for decades. In a new study published in the journal Research Notes of the American Astronomical Society, astronomers report the discovery of a mysterious object that appears to be a "quasi-moon," or a small asteroid that orbits the Sun, but in an arc that puts it near our planet for an extended period of time. Think of it as a cosmic situationship; though it's been following us for around 60 years, the object isn't gravitation

The Math of Catastrophe

In the 1960s, the Soviet climatologist and mathematician Mikhail Budyko set out to investigate the potential future of a planet on the brink of nuclear Armageddon. He started by looking some 600 million years into the past. Back then, some scientists claimed, the ancient planet was an iced-over snowball. Most researchers considered that a crackpot theory. Ice over the equator? Please. But Budkyo developed a mathematical model to back it up. If sea ice had been able to expand past a critical lat

A Collision With Another Planet Could Have Allowed for Life on Earth

wired.com Jorge Garay 2025-09-24 10:00:00

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that instead of being destroyed, it was transformed, incorporating the mass of that foreign body to become the planet we know. Recent research adds another layer of relevance to that hypothesized cosmic event: Scientists believe that without that other body, the basic conditions for life to emerge on Ear

Skygazers, get ready to head outside and spot the supermoon, coming in October. NASA says that a supermoon is any moon within 90% of perigee, which occurs when the moon is closest to Earth. During this time, the moon is approximately 226,000 miles away from our planet, roughly 25,000 miles closer than when it is in apogee. The full moon appears on Oct. 6, and you shouldn't have any trouble seeing it. It'll be the first of four consecutive supermoons, one each month, as the moon continues its el

Around 90% of an Earthquake’s Energy Doesn’t Do What You Think It Does

gizmodo.com Gayoung Lee 2025-09-27 15:30:30

Earthquakes can be deadly and disastrous. But what we feel may constitute a tiny sliver of an earthquake’s destructive energy, according to a new experiment. In a recent AGU Advances paper, researchers describe how they created “lab quakes,” or miniature versions of natural earthquakes created in a controlled laboratory. Doing so allowed the team to derive a complete energy budget for the quakes, a “simplified analog” of real-life earthquakes, they reported in the paper. Surprisingly, they fou

Here’s How to Deflect a Dangerous Asteroid Without It Totally Backfiring

In September 2022, NASA deliberately crashed a spacecraft into an asteroid, successfully altering the space rock’s trajectory. The orbital shove demonstrated an asteroid deflection technique that could come in handy if a massive rock were headed in Earth’s direction. As it turns out, however, deflecting a potentially threatening asteroid is only half the battle. Striking an asteroid for deflection purposes could send it back on a collision course with Earth, merely delaying the planet-shatterin

Scientists Find Evidence of Flowing Water on Giant Asteroid

Today, the near-Earth asteroid known as Ryugu is bone dry. But new research suggests that the half-mile space rock may have once been flowing with liquid water — and crucially, at a period in the solar system's history far later than when that would have been thought possible. The findings, published in a new study in the journal Nature, could add weight to the theory that soggy asteroids brought Earth its first stores of H2O billions of years ago.

Much of the world will get to witness the spectacle of a total lunar eclipse on Sunday night. A total lunar eclipse happens when the Earth passes between the Moon and the Sun, briefly aligning in a way that completely shadows the Moon. A full moon lunar eclipse happens in three phases. The first phase is the penumbral phase when the Moon starts to enter Earth’s shadow. Then the partial phase begins, when a part of the moon enters the deep part of Earth’s shadow called the umbra.

On the evening of September 7, the second (and final) total lunar eclipse of the year will take place—serving up the striking sight of a red “blood moon” in the sky across much of the world. Total lunar eclipses occur when the Earth is positioned between the full moon and the sun, with the moon falling into the shadow of our planet. However, rather than disappearing into darkness, the shadowed moon instead turns red. This is because of a phenomenon called Rayleigh scattering. Visible sunlight,
