(PhysOrg.com) -- At the edge of our solar system in December 2004, the Voyager 1 spacecraft encountered something never before experienced during its then 26-year cruise through the solar system an invisible shock formed as the solar wind piles up against the gas in interstellar space. This boundary, called the termination shock, marks the beginning of our solar system's final frontier, a vast expanse...
NASA’s Interstellar Boundary Explorer (IBEX) spacecraft, designed to image global interactions at the outer reaches of the solar system, today began its move to Vandenberg Air Force Base (VAFB), Calif. The IBEX spacecraft was loaded into a truck at Orbital Sciences Corporation, Va., where engineers integrated the science payload with the spacecraft and completed numerous tests to ensure optimum performance...
We study the consequences of the $f(R/\Box)$ gravity models for the Solar system and the large scale structure of the universe. The spherically symmetric solutions can be used to obtain bounds on the constant and the linear parts of the correction terms. The evolution of cosmological matter structures is shown to be governed by an effective time dependent Newton's constant. We also analyze the propagation...
Seed Magazine posted an interesting photo series documenting scientific laboratories after dark. Describing the top photo above - Much of the fundamental knowledge that underpins our search for extraterrestrial life and supports our understanding of our solar system's history and evolution emerges from this small room in Theodor Kostiuk's laboratory. On the rightmost table, infrared light from a powerful...
WASHINGTON -- Computer programs that are used to define safety margins for fiery spacecraft re-entries and help detect planets outside our solar system are co-winners of NASA's 2007 Software of the Year Award. Software engineers at NASA's Ames Research Center at Moffett Field, Calif., developed the Data-Parallel Line Relaxation, or DPLR, which is used to analyze and predict the extreme environments...
As I mentioned before , MiddleOne and I are building an Orrery , a model solar system. We are putting together one that is coming in parts as a magazine ( Build a Model Solar System ), so we have to wait about two weeks for a chunk of parts, and then we have to wait even longer to get enough parts to make a chunk of Orrery. But we finally got enough parts to get started, MiddleOne was champing at the...
Much of the Astrobiology believe that the best place in the Solar System where to look for extraterrestrial life is Europe, one of the major moons of Jupiter discovered by Galileo in 1610. The measurements of its magnetic field by the Galileo probe seem to confirm that the satellite is coated by a layer of ice and salt water about 100 km thick. It is precisely in this vast ocean where he hopes to find...
As expected, the Gliese 581 system did not disappoint and is now revealing the smallest planet outside our solar system, bringing the total number of planets found orbiting around the red dwarf star to three. When the star was first targeted by astronomers nearly two years ago, only a single planet was detected. The newly found object weighs about 5 times more than Earth, has a rocky surface, and its...
My eye on the sky Many (most) have had a very bumpy ride these last few days. The Moon in Pisces has cleared Uranus but now heads into a square with Pluto. Pluto! Those of us with planets at the late degrees of the mutable signs have just about had it but here comes some more. The good news is tomorrow this breaks and also it might help knowing you’re not alone. Personal as it is, it’s a collective...
With Predetermined Result Let me get your opinion on something. Who is currently the hottest babe on Fox News? Of course, we all know the answer. Lauren Green is easily the hottest babe in the solar system. So we won't...
We’ve decide we’re launching a brand new, occasional, well earned award system: ‘This Old Brit’s Stupidest Sod(s) in the Solar System Citation’.

THIRTY-NINE years to the day Neil Armstrong radioed "The Eagle has landed!" from the Sea of Tranquility, NASA is turning its eyes to the moon again in a first step towards settling the solar system. Go to our science and space special section. | THIRTY-NINE years to the day after Neil Armstrong radioed "The Eagle has landed!" from the Sea of Tranquility, NASA has turned its eyes toward the moon, gazing...
The apparent discovery of ice near Mars' north pole has scientists asking: Did the frozen water melt at some point in the planet's long history to create an environment friendly for life?
