Science editor Alan Boyle's blog: Commercial ventures have been taking lots of small steps toward the next giant leap in spaceflight — and the federal government is helping them out.

Why should politicians support trips beyond Earth orbit? It's good for jobs in the short term, and good for our survival in the long term. Commentary by NBC News' Jay Barbree.

Science editor Alan Boyle's blog: A picture from NASA's Mars Reconnaissance Orbiter paints the Red Planet in shades of blue, yellow and green — but there's a method in the madness.

Amateur astronomers and students around the world are taking a close look at the asteroid Eros as part of a hands-on experiment to measure solar-system distances.

NASA may not have space shuttles to launch people into the final frontier anymore, but that hasn't stopped Americans from lining up in droves for the chance to join the agency's iconic astronaut corps during the latest recruitment drive.

It’s a millisecond pulsar… a rapidly rotating neutron star and it’s about to reach the end of its mass gathering phase. For ages the vampire of this binary system has been sucking matter from a donor star. It has been busy, spinning at incredibly high rotational speeds of about 1 to 10 milliseconds and shooting [...]

Habitable zones are the regions around stars, including our own Sun, where conditions are the most favourable for the development of life on any rocky planets that happen to orbit within them. Generally, they are regions where temperatures allow for liquid water to exist on the surface of these planets and are ideal for “life [...]

This lovely image of Comet Garradd (C/2009 PI) as it passes by the globular cluster M92 in the constellation Hercules, was taken remotely from the Tzek Maun Observatory in New Mexico by our friends Giovanni Sostero, Ernest Guido and Nick Howes. While the two objects look like they are right next to each other, M92 [...]

Do you live here? Tens of millions of Earthlings live and work in the bustling and seemingly intertwined American mega-metropolis of the Philadelphia-New York City-Boston corridor (bottom-center splotch) captured in this stunning “Cities at Night” panorama of the East Coast of the United States along the Atlantic seaboard (image above). Look northward and you’ll see [...]

This is why I always keep a pair of 3-D glasses by my computer. This well-preserved crater on Mars may look like just your average, run-of-the-mill impact crater in 2-D, but in 3-D, the sharply raised rim, the deep, cavernous crater body, and especially the steep crater walls will have you grabbing your armchairs so [...]

The Rosetta mission will do something never before attempted: land on a comet. The spacecraft is now on its way to intercept comet 67P/Churyumov-Gerasimenko in January 2014 and land a probe on it for what promises to be an amazing view. But what we know of comets so far comes from a few flyby missions. [...]

According to conventional thinking, plant life first took hold on Earth after oceans and rivers formed; the soil produced by liquid water breaking down bare rock provided an ideal medium for plants to grow in. It certainly sounds logical, but a new study is challenging that view – the theory is that vascular plants, those [...]

Is this what we look like? Astronomers don’t know for sure exactly what the Milky Way looks like, but searching out other barred spiral galaxies like this one is helping scientists to learn more about our home. Galaxy NGC 1073 is located in the constellation of Cetus (The Sea Monster).Most of the known spiral galaxies [...]
