Black holes are massive, mostly invisible and so powerful not even light can escape them. So what would happen if one entered our solar system? It depends on a lot of factors, including the size and distance of the black hole, experts told Live Science. But in many scenarios, not much would happen.”They’re not, per … Read more
Only about 600 people have ever traveled to space. The vast majority of astronauts over the past six decades have been middle-aged men on short-duration missions of fewer than 20 days. Today, with private, commercial and multinational spaceflight providers and flyers entering the market, we are witnessing a new era of human spaceflight. Missions have … Read more
“Warp drives” used by super-advanced alien civilizations may create specific space-time ripples in their wake that we can spot from Earth, a new paper argues. However, the jury is still out on whether the faster-than-light technology is even possible to create in the first place. A warp drive is a hypothetical device that enables an … Read more
The James Webb Space Telescope has discovered the oldest and most distant supernova ever seen — a stellar explosion that took place when the universe was just 1.8 billion years old. The ancient starburst was uncovered among 80 others in a patch of sky that, from our perspective on Earth, is about the width of … Read more
A planet beyond the solar system that has been compared to Spock’s homeworld Vulcan in the Star Trek franchise may have been nothing more than an illusion caused by a jittery star. The extrasolar planet or “exoplanet” (a term for a planet outside of our solar system) was proposed to orbit a star called 40 … Read more
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
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
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
