Anticipation is still building for next weekend's premiere of Interstellar, with lots of posts focusing on the science of the film - including a documentary on the Science Channel. Discovery News thinks the film's black hole is the best such depiction in science fiction films, and Rhett Allain of Dot Physics explored the physics of the spinning spacecraft in the film. But Interstellar Travel Won't Look Anything Like The Movie. Mae Jemison, the astronaut leading humankind's journey to the stars, says if we want to get to another Earth, we'll have to expand our thinking.

Popular Science says science fiction’s favorite method for exploring the universe won't be easy.

NASA's launch of its Antares mission ended in smoke and flames earlier this week when the rocket exploded after liftoff. The disaster is stark reminder of the 'incredible dangers' of spaceflight, a former NASA engineer and analysts told the Guardian. Related: What Science Lost in the Antares Rocket Explosion. Also: Sad students see science experiments go up in smoke aboard Antares rocket. Children at schools in Texas, New Jersey and Michigan had worked for a year to develop projects for the International Space Station. It seems the Operator Blew Up Antares Rocket Deliberately to minimize damage after the launch went wrong.

That event was overshadowed on Friday, however, when tragic news broke that Virgin Galactic's SpaceShip Two Had Been Lost during a test flight – with one major injury and One Pilot Confirmed Dead. Space Tourism Isn't Worth Dying For, per Adam Rogers in Wired: "Virgin Galactic is building the world’s most expensive roller coaster, the aerospace version of Beluga caviar. It’s a thing for rich people to do: pay $250,000 to not feel the weight of the world."

Dwarf Galaxies Dim Hopes of Dark Matter. For five years physicists have been tantalized by possible evidence of dark matter in the Milky Way’s center. But new results from small satellite galaxies have complicated the story. Related: Fresh hints of dark matter at Milky Way's core.

Does the Universe Violate the Laws of Thermodynamics? Total energy must be conserved. Every student of physics learns this fundamental law. The trouble is, it does not apply to the universe as a whole.

How will the universe end? A bubble of alien matter will consume us all. Alina Simone, daughter of cosmologist Alex Vilenkin, interviews him to better understand a recent talk he gave at the Hayden Planetarium in New York City. Alina: "I’m kind of picturing the universe as this nice, merino wool blanket and then suddenly this giant moth appears and eats the whole thing." Vilenkin (confused): "A mop?"

Seeking the Source of Cosmic Rays. "Compared with the electronics at the Auger, Whiteson says, “individual smartphones are really lousy detectors.” Link enough of them together, however, and the weakness of each phone becomes less important. And it costs next to nothing for smartphones to cover an area much larger than twelve hundred square miles." Related: Two groups have released early versions of apps to turn your smart phone into a cosmic ray detector.

Einstein’s greatest legacy- How demons and angels advanced science. "Einstein’s greatest legacy is not General Relativity, it’s not quantum entanglement, and it’s not slices of his brain either.

Rosetta's comet stinks -- literally. "if you could take a whiff of the cloud of gas surrounding the icy nucleus of comet 67P/Churyumov-Gerasimenko you would smell a pungent mix of hydrogen sulfide (rotten eggs); ammonia (horse stable); and formaldehyde. There would also be a hint of vinegar (sulfur dioxide) and a whiff of alcohol (methanol). Carbon disulfide would add just a touch of sweetness."
