Galaxies, Stars and Nebulae series A great outer space picture featuring a three-colour composite image of the Omega Nebula (Messier 17, or NGC 6618), based on images obtained with the EMMI instrument on the ESO 3.58-metre New Technology Telescope at the La Silla Observatory. North is down and East is to the right in the image. It spans an angle equal to about one third the diameter of the Full Moon, corresponding to about 15 light-years at the distance of the Omega Nebula. The three filters used are B (blue), V ("visual", or green) and R (red).

Unexpectedly little black-hole monsters rapidly suck up surrounding matter

more »
Researchers have found evidence that enigmatic objects in nearby galaxies -- called ultra-luminous X-ray sources (ULXs) -- exhibit strong outflows that are created as matter falls onto their black holes at unexpectedly high rates. The strong outflows suggest that the black holes in these ULXs must be much smaller than expected. Curiously, these objects appear to be "cousins" of SS 433, one of the most exotic objects in our own Milky Way Galaxy. The team's observations help shed light on the nature of ULXs, and impact our understanding of how supermassive black holes in galactic centers are formed and how matter rapidly falls onto those black holes.

Fuel-free nanomotor is powered by ultrasound and magnetic fields

more »
(Phys.org)—Nanoscale motors, like their macroscale counterparts, can be built to run on a variety of chemical fuels, such as hydrogen peroxide and others. But unlike macroscale motors, some nanomotors can also run without fuel, instead being powered by either magnetic or acoustic fields. In a new paper, researchers for the first time have demonstrated a nanomotor that can run on both magnetic and acoustic fields, making it the first magneto-acoustic hybrid fuel-free nanomotor.

Planet Aurora

more »
What bizarre alien planet is this ? It's planet Earth of course, seen through the shimmering glow of aurorae from the International Space Station. About 400 kilometers (250 miles) above, the orbiting station is itself within the upper realm of the auroral displays, also watched from the planet's surface on June 23rd. Aurorae have the signature colors of excited molecules and atoms at the low densities found at extreme altitudes. The eerie greenish glow of molecular oxygen dominates this view. But higher, just above the space station's horizon, is a rarer red band of aurora from atomic oxygen. The ongoing geomagnetic storm began after a coronal mass ejection's recent impact on Earth's magnetosphere.

Supercomputer model shows planet making waves in nearby debris disk

more »
A new supercomputer simulation of the planet and debris disk around the nearby star Beta Pictoris reveals that the planet's motion drives spiral waves throughout the disk, a phenomenon that causes collisions among the orbiting debris. Patterns in the collisions and the resulting dust appear to account for many observed features that previous research has been unable to fully explain.

NGC 602 bright stars Cover For The iPad Mini

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: nasa, space, astronomy, shuttle, hubble, bright, star, starry, blue, nebula

NGC 602 is a young, bright open cluster of stars located in the Small Magellanic Cloud (SMC), a satellite galaxy to the Milky Way. Radiation and shock waves from the stars have pushed away much of the lighter surrounding gas and dust that compose the nebula known as N90, and this in turn has triggered new star formation in the ridges (or "elephant trunks") of the nebula.
