SpaceX, a private space company, is trying again on Friday to launch its Dragon spacecraft to the International Space Station. Its first attempt to launch this mission was scratched on Monday because of a helium leak.
Modern explorers have found a previously unknown ocean -- but this one's on Saturn's moon Enceladus. Learn more from Chabot Space & Science Center's Ben Burress at KQED Science.
SpaceX is launching a rocket to the International Space Station this afternoon. The live webcast begins at 12:45 PST and the launch itself is scheduled for 1:58.
It'll be a great view in the Bay Area late on the night of April 14, as long as clouds don't cover up the moon.
Upholding a long-standing tradition of showing us things in space that we have never seen before, the Hubble Space Telescope recently witnessed the break-up of an asteroid.
Having solved a 42-year-old mystery about lunar "streamers," the $280 million LADEE spacecraft is set to vaporize when it collides with the moon around April 21st.
Getting sick in space is no picnic. So scientists are sending bugs to the International Space Station, hoping to better predict some of the physical challenges that may befall astronauts when NASA eventually sends the first human mission to Mars.
Chances are you read a headline about the Big Bang earlier this week. Perhaps you clicked to an article about it and started reading up. But you may still have some burning what-is-this-Big-Bang-news-anyway questions.
A recent study of data collected by NASA's Wide-Field Infrared Explorer (WISE) spacecraft may have exorcised the notion of the hypothetical existence of the fabled "Planet X."
In one of the first tiny fractions of an instant after the Big Bang, the Universe expanded explosively, faster than the speed of light. That exponential expansion of, well, everything, is described by the theory of inflation, which may now be confirmed.
Investigation of an ancient Martian meteorite has re-fueled a debate about evidence of possible past life on Mars.
Experts have tracked a group of rare meteorites back to a single source on Marsthe crater Mojave near the red planet's equator.
NASA researchers announce they've verified 715 new planets orbiting around 305 stars.
Recent observations of the dwarf planet Ceres by the European Herschel Space Observatory have revealed for the first time the presence of water vapor on this object in the Main Asteroid Belt.
The NASA spacecraft is designed to answer a 42-year-old mystery about lunar dust, but it's also snapping photos along the way.
To be successful Mars colonists, future astronauts will need to know both the potential hazard and utility of the soil. One unusual compound that has garnered quite a bit of attention is called perchlorate; it has the potential to be both a blessing and a curse for future explorers.
On Monday, far beyond the orbit of Mars, an alarm clock went off and a robot began the slow process of waking up after a long, cold sleep. The European Space Agency's Rosetta spacecraft is now approaching the comet 67P/Churyumov–Gerasimenko, which it will catch up with this May.
John Dobson, the co-founder of San Francisco Sidewalk Astronomers and the inventor of a telescope that people can build themselves, died on January 15 in Burbank. He was 98. For decades, Dobson introduced the public to the sky, setting up telescopes in cities and parks and inviting passers-by to take a look into space. And […]
