Milky Way Panorama 2.0 Print

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


tagged with: milky way, all sky, all-sky, milky way panorama, axel mellinger, galaxy, big dipper, orion, astronomy, astrophotography

Between October 2007 and August 2009, Central Michigan University physics professor Axel Mellinger assembled a digital all-sky mosaic image from more than 3000 individual CCD frames, which he took from remote, dark sites in South Africa, Texas and Michigan. The result is a panoramic image of our home galaxy that no stargazer could ever see from a single spot on Earth. It shows stars 1000 times fainter than those visible to the unaided human eye.

For more information, visit Dr. Mellinger's Milky Way home page at http://home.arcor-online.de/axel.mellinger/.

Why you probably don't have Ebola -- even if you shook hands with America's 'patient zero'

Science Focus

original post »

After a hectic trip from Liberia's capital of Monrovia to the airport, you finally make it onto your U.S.-bound plane and take your seat. The man next to you appears healthy and friendly. You introduce yourself, shake hands, and have an uneventful journey of small talk as you head back to Dallas, Texas. A few days later, you receive an urgent call from the Centers for Disease Control and Prevention: The man who sat next to you on the plane just tested positive for the Ebola virus.

You start to feel panic rise in your chest, reliving the fateful handshake over and over. Your anxiety is perfectly...

New method for detecting water on Mars

more »

An undergraduate student has helped develop a new method for detecting water on Mars. Water is a key indicator for the potential of microbial life on the red planet. While reseachers didn't see evidence of it from two sites they studied, their method could look for water elsewhere.

Aurora and Milky Way in a Little Sky

more »
Stepping stones seem to lead to the Milky Way as it stretches across this little sky. Of course, the scene is really the northern hemisphere's autumnal equinox night. Water and sky are inverted by a top to bottom, around the horizon stereographic projection centered on the zenith above Lake Storsjön in Jämtland, Sweden. In the north the Milky Way arcs from east to west overhead as fall begins, but the season is also a good time for viewing aurora. Geomagnetic storms increase in frequency near the equinox and produce remarkable displays of northern lights at high latitudes, like the eerie greenish glow reflected in this watery cosmos.

Superposition revisited: Proposed resolution of double-slit experiment paradox using Feynman path integral formalism

more »

(Phys.org) —The Schrödinger's Cat thought experiment, published in 1926 by Erwin Schrödinger, may be the most widely-known metaphorical explanation of quantum superposition and collapse. (Superposition is a fundamental principle of quantum mechanics stating that a physical system – such as a photon or electron – simultaneously exists partly in all theoretically possible states; but when measured or observed gives a result corresponding to only one of the possible states.)

Ultrafast remote switching of light emission

more »

Researchers can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.

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

Galaxies, Stars and Nebulae series The tip of the "wing" of the Small Magellanic Cloud galaxy is dazzling in this new view from NASA's Great Observatories. The Small Magellanic Cloud, or SMC, is a small galaxy about 200,000 light-years way that orbits our own Milky Way spiral galaxy.
The colors represent wavelengths of light across a broad spectrum. X-rays from NASA's Chandra X-ray Observatory are shown in purple; visible-light from NASA's Hubble Space Telescope is colored red, green and blue; and infrared observations from NASA's Spitzer Space Telescope are also represented in red.
The spiral galaxy seen in the lower corner is actually behind this nebula. Other distant galaxies located hundreds of millions of light-years or more away can be seen sprinkled around the edge of the image.
The SMC is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans.
