It's good to know that NASA isn't wholly focused on that orbiting
headache known as the International Space Station. The agency is still
searching for answers to the grand questions. Yesterday, NASA
established the new Einstein Probes Office to support several wild
astrophysics missions that fall in the Beyond Einstein Program. Yes,
it's just an administrative move, but we're still happy to see that
programs like LISA, an on again, off again space-based observatory
that will listen for gravity waves that roll out of merging black
holes, are progressing.
Even more exciting are the three finalists (ADEPT, Destiny and SNAP) competing for a slot to solve one of the more perplexing
mysteries in the cosmos, the nature of dark energy, the strange force
that's practically blowing our universe apart.—Gregory Mone

It looked bad for LIGO last year. Critics were grumbling that one of the most sensitive listening devices in history was, at $365 million, too expensive. LIGO (short for Laser Interferometer Gravitational Wave Observatory) is designed to hunt for gravity waves-energetic ripples that distort the shape of space. These waves could inform scientists about violent events that occurred long ago in the distant universe, such as supernovas or the merging of black holes. But gravity waves lose strength as they travel across the cosmos.
