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 […]
Let's take a moment to tally a few of 2013's highlights of astronomy and space exploration. In brief, it was a very good year on a number of fronts.
From the debut of the world's largest solar plant to Comet ISON, zombified bees to the physics of sailing — it's been another year of diverse storytelling from the KQED Science team. Here's a round-up of our top 10 stories (based on page views) that you've enjoyed in 2013.
Comet ISON is gone, Comet Lovejoy remains and a sun-grazing asteroid, 3200 Phaeton, is showing comet-like behavior. An interesting December to say the least.
In San Francisco this week, NASA scientists presented rare video footage of the Earth and moon, plus a first for citizen space science.
If you had to make a choice to shut down either the Mars rover Curiosity or that explorer of the Saturn system Cassini, would you deliver a pink slip to the young, eager, energetic newbie or force an early retirement on a veteran explorer who has delivered volumes of knowledge?
Comet ISON may not have survived its close brush with the Sun, but astronomers are still going to "study the heck out of it," says Foothill College astronomy professor Andrew Fraknoi.
