A new technique might soon enable cosmologists to map the universe even when they can't pick out individual galaxies. If it works, researchers would be able to probe the structure of 500 times as much of the universe as they have studied so far.

The article came out some time ago of course and was posted here, though the story here is still well written. If you are lazy to read the rel long article, here the summary explanation: The team found that a good half of the force came from heat from the RTGs, which bounced off the back of the spacecraft antenna. The other half came from electrical heat from circuitry in the heart of the spacecraft. Most of that heat was radiated through louvers at the back of the probes, which weren't as well insulated as the rest of their bodies, further contributing to the deceleration.

Team leader Professor Steven Tingay, Director of the MWA at Curtin University and Chief Investigator in the Australian Research Council Centre for All-sky Astrophysics (CAASTRO) said the MWA will be able to detect the space junk by listening in to the radio signals generated by stations including popular youth network Triple J.
Dwarf planet could illuminate the dark sector - 1 views

A dwarf-planet candidate called UX25 and its tiny satellite could provide the first evidence of a new cosmological model that includes antigravity, say Alberto Vecchiato and Mario Gai of the Astrophysical Observatory of Turin in Italy.

With a purpose-built radio telescope, the approach could map as much as 50% of the observable universe far faster and cheaper than galaxy surveys can, Loeb says.

But "to really get a handle" on Titan's methane cycle, they'll need to monitor the exchange of methane between the lakes and the atmosphere. And that, she says, will require "a future lake-lander mission."

One of the quasar's jets is aimed directly at the galaxy, and the team thinks it's likely that the jet is driving the star-making process by blasting matter into the galaxy.

Is exoplanet a 'waterworld'? - 0 views

Together, these parameters suggest that GJ 1214b has the same density of water – and Charbonneau told physicsworld.com that it is very likely that the exoplanet is made entirely of liquid water.

RHIC nets strange antimatter - 0 views

The antihypertriton – consisting of an antiproton, an antineutron and an antilambda particle – is the heaviest antinucleus yet produced and opens up a new realm of strange antinucluei. It could also shed light on a number of problems in astrophysics and cosmology, including the dominance of matter over antimatter in the universe.

Researchers Solve the Mystery of the Zodiacal Light - 0 views
-
Zodiacal light—the faint white glow that stretches across the darkest skies, tracing the same path the sun takes—has mystified scientists for centuries. They've known that it is sunlight reflected from a disk of dust spanning the inner solar system from Mercury to Jupiter. They just didn’t know where the dust came from—until now.
