Ever wondered what it would be like to fall into a black hole? A new NASA simulation has the answer — including the inevitable, crushing end. Researchers created the new simulation using the Discover supercomputer at the NASA Center for Climate Simulation. It shows a viewer plunging through the accretion disk of glowing gas around … Read more
A private Japanese company has taken the world’s first close-up photo of an individual piece of space debris, by parking another satellite next to it in orbit. This orbital photo op is the first step in an ongoing mission to capture and destroy potentially hazardous pieces of space junk that are clogging up our sky. … Read more
A collection of rocks scattered on an ancient shoreline on Mars might indicate that the Red Planet was once far more Earth-like than scientists previously thought. The rocks, discovered by NASA’s Curiosity rover, are unusually rich in manganese oxide — a chemical that adds to growing evidence that the once-habitable Mars may have sported Earth-like … Read more
The “gateway to the underworld,” a huge crater in Siberia’s permafrost, is growing by 35 million cubic feet (1 million cubic meters) every year as the frozen ground melts, according to a new study. The crater, officially known as the Batagay (also spelled Batagaika) crater or megaslump, features a rounded cliff face that was first … Read more
It would appear that the so-called “great instability” event that wreaked chaos among the planets, sending the gas giants careening through space until they settled into the orbits we know today, occurred between 60 and 100 million years after the birth of the solar system. This is the conclusion of some careful scientific detective work … Read more
Astronomers have long believed that the ice giants Uranus and Neptune are rich in frozen water. However, a new study suggests they may also have tons of methane ice. The findings could help solve a puzzle about how these icy worlds formed. Much about Uranus and Neptune remains unknown. These ice giant worlds have had … Read more
NASA test drove the mini autonomous rovers that will soon fly to the moon and collectively map the lunar surface. The rovers are part of a technology demonstration called Cooperative Autonomous Distributed Robotic Exploration (CADRE), which is designed to show that a group of robotic spacecraft can work together without direct human control. NASA took … Read more
The solar system is an enormous place. Our cosmic neighborhood includes eight planets, around half a dozen dwarf planets, several hundred moons and millions of asteroids and comets, all spinning around the sun — and in many cases each other —at speeds of thousands of miles per hour, like a giant top. But where does … Read more
Sea levels are rising as climate change rapidly melts glaciers and ice sheets and the water within the oceans expands in a warming world. But have sea levels ever been higher than they are today? And when were they the highest? In short, sea levels have easily been higher than they are today. But it’s … Read more
About one in every 12 stars may have swallowed a planet, a new study finds. Previous research had discovered that some distant stars possess unusual levels of elements, such as iron, which one would expect to make up rocky worlds such as Earth. This and other evidence suggested that stars may sometimes ingest planets, but much remained uncertain … Read more
