Planets form in disks of dust and gas that surround young stars. A look at the birth places means a journey into the past of Earth and its siblings. Now, astronomers have been able to obtain detailed images of the protoplanetary disks of two stars using the Subaru telescope in Hawaii.
New observations with the Very Long Baseline Array have made the farthest direct distance measurement ever, a key step toward understanding the mysterious Dark Energy that constitutes some 70 percent of the Universe. Other observations are redrawing the map of our home Galaxy and promise to revise our understanding of extrasolar planets.
A powerful solar flare has ushered in the largest space weather storm in at least four years and has already disrupted some ground communications on Earth.
Bring a filter if you plan on drinking water from the moon. Water ice recently discovered in dust at the bottom of a crater near the moon
The nebula Messier 78 takes center stage in this image taken with the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile, while the stars powering the bright display take a backseat. The brilliant starlight ricochets off dust particles in the nebula, illuminating it with scattered blue light. Igor Chekalin was the overall winner of ESO
The Sun has unleashed its strongest flare in four years, observers say.
Could there be a massive planet well beyond the orbit of Pluto? Unfortunately, this "extraordinary" claim is based on rather "ordinary" evidence.
US President Barack Obama wants more money to go towards developing commercial rockets and capsules to take American astronauts into orbit.
A proposed private spaceship designed to carry astronauts by the commercial space firm in Virginia has a new name steeped in mythology: Prometheus. The company Orbital Sciences unveiled the Prometheus space plane name Feb. 1.
The US company SpaceX is working on the first-ever reusable rocket to launch to space and back, with the goal of one day helping humans colonize Mars, founder Elon Musk said Thursday.

(PhysOrg.com) -- Our Milky Way galaxy, like other spiral galaxies, has a disk with sweeping arms of stars, gas, and dust that curve around the galaxy like the arms of a huge pinwheel.
