Charting the slow death of the universe

more »
Astronomers studying more than 200,000 galaxies have measured the energy generated within a large portion of space more precisely than ever before. This represents the most comprehensive assessment of the energy output of the nearby Universe. They confirm that the energy produced in a section of the Universe today is only about half what it was two billion years ago and find that this fading is occurring across all wavelengths from the ultraviolet to the far infrared. The Universe is slowly dying.

Physicist unveils plan for entangling massive objects

more »
(Phys.org)—Roman Schnabel, a physics professor at the Max Planck Institute for Gravitational Physics has published a paper in the journal Physical Review Letters outlining a plan for entangling two "massive" objects. He and his team are still working on a way to actually carry out the plan, but if successful, the group would succeed in entangling two 0.1 kg mass mirrors, which would represent a much larger example of entanglement than anything that has come before—up till now the largest objects to be entangled were of micron size.

Saturn Solar Eclipse Poster

Here's a great poster featuring a beautiful image from deep space


tagged with: space, astronomy, saturn, stars, planets, earth, cassini, sun, exploration, rings, moons

You may think that this is a fake image, but it is actually a real photo taken from the Cassini space craft of Saturn eclipsing the Sun. The rings glow brightly as the light filters through them and the reflect that light all the way around to the back of the planet creating a surreal effect. A special surprise in the photo is that, just to the left of the rings, that bright blue dot is Earth, where you're sitting right now. This is truly a fascinating and beautiful image.

Stellar Nursery R136 in the Tarantula Nebula Rectangular Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: galaxies, dorneblmc, stellar nursery, 30 doradus nebula, large magellanic cloud, amazing hubble images, tarantula nebula, r136, star cluster, astronomy pictures, massive stars

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.

Narrowing the gap between synthetic and natural graphene

more »
Producing graphene in bulk is critical when it comes to the industrial exploitation of this exceptional two-dimensional material. To that end, researchers have developed a novel variant on the chemical vapor deposition process which yields high quality material in a scalable manner. This advance should significantly narrow the performance gap between synthetic and natural graphene.
