More Belt-Tightening in Store for NASA as STEM Education Programs Face Consolidation
The White House Office of Management and Budget (OMB) has just released President Obama’s budget request for 2014. It will take some time for the budget’s full impacts on science to be dissected and debated, but here is a quick look at how one closely watched agency—NASA—fared.The president’s budget, which is subject to Congressional negotiation and approval, would provide $17.7 billion for NASA, down a bit from the previous year...

Cosmos Study Dashes Hope for New Neutrino
First particle physicists discovered “a boring old Standard Model Higgs boson,” as my colleague Michael Moyer put it, meaning that the particle hewed closely to theoretical predictions and offered little in the way of guidance to new and exciting physics...

Tracking the location of the Voyager 1 spacecraft can be exhausting for a science journalist, and I can only imagine how confusing it gets for the interested reader.
Quasars at 50: Luminous Cosmic Beacons Remain a Puzzle
Fifty years ago, in the journal Nature, astronomer Maarten Schmidt published a brief paper noting that a star-like object known as 3C 273 was simply too far away to be a star in the Milky Way...

Astronomer Locates Previously Unseen Neighbor to the Sun
When NASA launched the WISE satellite in 2009, astronomers hoped it would be able to spot loads of cool, dim objects known as brown dwarfs. Bigger than a planet, a brown dwarf is not quite a star, either—it is too small to sustain the nuclear fusion reactions that turn hydrogen to helium...
Naked-Eye Comet Pan-STARRS Climbing into Northern Skies
This year is shaping up to be a great one for amateur sky-watchers. Toward the end of 2013, astronomers expect the recently discovered Comet ISON (officially designated C/2012 S1) to shine mightily as it approaches the sun—possibly glowing as bright as the full moon...
Commercial Spaceflight Industry Drifts Back to Earth
As the brash, stylish new kid on the block, SpaceX was sure to win its share of admirers. But last week’s launch hiccup showed that the private space operator, helmed by Elon Musk, has a few issues to work out, just like stodgy old NASA.Don’t get me wrong: SpaceX has done unbelievably impressive things...

Hundreds Reported Injured in Blast from Meteor Strike over Russia [Video]
A meteor fireball lit up the morning sky over Chelyabinsk in central Russia, producing a shock wave that shattered windows and injured an estimated 500 1,000 people.** Although much of the parent object likely burned up in the atmosphere, Russian authorities say that several meteorite fragments have already been recovered, according to the Interfax news agency.A preliminary analysis posted to the Web site of the Russian Academy of Sciences estimates that the object that struck Earth's atmosphere was a few meters in diameter, "the weight of the order of ten tons [and] the energy of a few kilotons," according to a Google translation.* That would make the Chelyabinsk event a fairly common occurrence, although such strikes usually occur over less-populated regions, not cities of more than a million people...
