An idea born in unsettled times becomes a feat of engineering excellence. The most complex machine ever built to bring humans to and from space and eventuall...

How will the Universe die? Everybody dies. The universe too? Well, probably. What are the current theories about the end of everything? And how creepy exactly? Very creepy but there is still hope and billions of years in between.

The European spacecraft Rosetta has become the first ever to catch up with a comet. It is a landmark step in a decade-long mission that scientists hope will help unlock some of the secrets of the solar system. Rosetta will accompany comet 67P/Churymov-Gerasimenko on its trip around the sun and land ...

On May 25, 2012 SpaceX made history when the Dragon spacecraft became the first privately developed vehicle in history to successfully attach to the International Space Station. Previously only four governments -- the United States, Russia, Japan and the European Space Agency -- had achieved this fe...

Watch as NASA astronauts Christina Koch and Jessica Meir prepare tools necessary for their spacewalk duties outside of the International Space Station on Friday, October 18, 2019.

Jupiter has a lot going on, with massive storms, intense winds, auroras, and severe temperature and pressure extremes. The James Webb Space Telescope of NASA has now taken fresh images of the planet. Webb's Jupiter observations will provide scientists with much more information about Jupiter's inner...

SpaceX’s massive Starship rocket exploded minutes after it cleared the launch pad during a flight test Thursday. Elon Musk had said the test posed steep challenges and risks.

Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in fro

We don’t yet know what the James Webb Space Telescope will uncover. Will we get answers? Will we have more questions? One thing’s certain: The story of us is a never-ending quest for knowledge.

The goal of 3-D printing is to take this capability to microgravity for use on the International Space Station. In space, whatever astronauts have available on orbit is what they have to use -- but just like on Earth, parts break or get lost. When that happens, there's a wait for replacement parts, ...
