Writer Fuel: Passing Stars May Have Altered Earth’s Orbit – And Climate – Many Times

Earth and two suns - deposit photos

Earth’s present-day climate change is human-induced, but the gravitational tugs of other planets can also cause long-term climatic patterns by slightly changing our planet’s orbit. Now, research suggests that massive passing stars can alter Earth’s path, too — and that these cosmic tugs may limit researchers’ ability to study the links between past changes in … Read more

The solar system holds many secrets that scientists are still trying to unravel. To help shed light on these mysteries, researchers are turning to space rocks of all kinds that may hold clues to the lost story of our solar system’s past. This approach is already bearing fruit: In October 2023, NASA’s OSIRIS REx mission … Read more

Writer Fuel: Are Tiny Black Holes Altering the Earth’s Orbit?

runaway black hole

Some of the universe’s oldest black holes swoop past our cosmic neighborhood at least once every decade, moving planets in their wake, a new study suggests. And if scientists can detect them, it would provide the first proof that these black holes exist as dark matter. Black holes, regions of immense gravity that even trap … Read more

Writer Fuel: Earth Has a Quasi Moon

earth and asteroid

Scientists recently discovered an asteroid that tags along with Earth during its yearly journey around the sun. Dubbed 2023 FW13, the space rock is considered a “quasi-moon” or “quasi-satellite,” meaning it orbits the sun in a similar time frame as Earth does, but is only slightly influenced by our planet’s gravitational pull. It is estimated … Read more

Writer Fuel: Earth Unlikely to Be Hit By Planet Killer Asteroid in Next 1,000 Years

Asteroid - deposit photos

Rest easy: Earth probably won’t be creamed by a killer asteroid in the next 1,000 years. New research accepted for publication in The Astronomical Journal and available on the preprint server arXiv.org finds that none of the kilometer-wide (0.6 mile) asteroids that travel near Earth are likely to hit the planet in the next millennium. … Read more

If intelligent aliens are searching for other advanced lifeforms in the galaxy, our cell phone towers could be the beacons that give Earthlings away. New research suggests that advanced aliens in nearby star systems could probably already detect radio signals from cell phone towers. And as these signals become more powerful, humanity’s calling card will … Read more

High-definition radar satellites have revealed more than 19,000 undersea volcanoes around our planet, providing scientists with the most comprehensive catalog of seamounts ever created. The new compendium, which was published April 6 in the journal Earth and Space Science, could provide a better understanding of ocean currents, plate tectonics and climate change. Prior to this, … Read more

Deserts can take many forms — including sweeping sand dunes, rocky canyons, sagebrush steppes and polar ice fields. But they’re united by one thing: a lack of rainfall. Generally speaking, anywhere that gets less than 10 inches (25 centimeters) of rain a year counts as a desert, said Lynn Fenstermaker, an ecologist at the Desert … Read more

The moon’s orbit around Earth appears so regular that civilizations have based the month on lunar motion for thousands of years. However, the moon is actually creeping slowly away from Earth. So will Earth lose its moon at some point? Scientists determined the rate at which the moon is drifting away from Earth with help … Read more
