President Barack Obama unveiled his 2015 budget proposal Tuesday, outlining his spending and policy priorities for the upcoming year. In it, President Obama earmarked funding for both his Climate Action Plan and Climate Resiliency Fund. The budget for the U.S. Environmental Protection Agency (EPA)—the agency that released stricter fuel standards this week—represented a $309 million decrease from the current fiscal year budget. The nearly $8 billion…

Some jumbo stars commit stellar suicide in surprisingly lumpy explosions, according to a new study in Nature. Scientists led by Caltech’s Brian Grefenstette looked at Cassiopeia A, a supernova that first appeared in nighttime skies around the year 1670. The supernova’s wispy remnants rest some 11,000 light-years away from Earth, stretched across some 59 trillion miles (95 trillion…

No place like home for the holidays? Two American astronauts aboard the International Space Station (ISS) will be floating outside their orbiting home on Christmas Eve.   While a Saturday space walk to repair the orbiting laboratory’s faulty cooling pump was completed ahead of schedule, water leaks still plague one space-walk spacesuit. As a result,…

Tensions are high as the astronauts aboard the International Space Station ready themselves to conduct a series of emergency spacewalks that start this weekend, ones intended to correct a critical cooling system failure. Acting much like a car’s radiator, the malfunctioning cooling pump prevents overheating of electronics and science experiments aboard the ISS. With one…
