More evidence for groundwater on Mars: Conditions would be conducive for microbial colonization if on Earth

more »

Scientists investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability. On the plateau, ELDs consist of rare mounds, flat-lying deposits, and cross-bedded dune fields. They interpret the mounds as smaller spring deposits, the flat-lying deposits as playa, and the cross-bedded dune fields as aeolian. They write that groundwater fluctuations appear to be the major factor controlling ELD deposition.

Nanoscale worms provide new route to nano-necklace structures

more »

Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

3,000 atoms entangled with a single photon

more »

Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in the journal Nature, represent the largest number of particles that have ever been mutually entangled experimentally.

Surprising gamma ray signal in satellite galaxy could come from WIMPs

Science Focus

original post »

Like moons orbiting a planet, there are smaller bodies circling the Milky Way. Known as dwarf galaxies, they can be dim enough to escape detection—it’s not known how many there are in total, and new dwarfs are still being detected. One such dwarf galaxy was discovered within the last few weeks using data from the Dark Energy Survey, an experiment that scans the southern sky in order to learn about the accelerating expansion of the Universe (the experiment’s name comes from the mysterious dark energy that causes that acceleration).

The dwarf, known as Reticulum 2, is about 98,000 light-years from Earth, making it one of the Milky Way’s closest discovered satellites. But that’s not its most exciting feature. The mini-galaxy seems to be emitting a strong gamma ray signal, a research team concludes in a paper submitted to the journal Physical Review Letters. That’s surprising for a dwarf, since they tend to be mostly devoid of the objects that typically produce gamma rays. While it’s too early to say for sure what the source of the gamma rays is, the authors have tentatively come to a very intriguing conclusion: dark matter annihilation.

Dwarfs and dark matter

Like their larger counterparts, dwarf galaxies rest within a spherical blob, or halo, of dark matter that accounts for most of the galaxy’s mass. In the case of the Milky Way’s satellites, their halos rest within the Milky Way’s own larger halo, making them subhalos.

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).

NGC 2403 in Camelopardalis

more »
Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish glow of atomic hydrogen gas. The giant HII regions are energized by clusters of hot, massive stars that explode as bright supernovae at the end of their short and furious lives. A member of the M81 group of galaxies, NGC 2403 closely resembles another galaxy with an abundance of star forming regions that lies within our own local galaxy group, M33 the Triangulum Galaxy. Spiky in appearance, bright stars in this colorful galaxy portrait of NGC 2403 lie in the foreground, within our own Milky Way. Tomorrow's picture: pixels in space

Dumbbell Nebula in Taurus Oval Stickers

tagged with: awesome astronomy images, inspirational, dmbblneb, vulpecula constellation, intense ultraviolet radiation, messier 27 ngc 6853, heavens, stars, dumbbell nebula, the fox constellation, european southern observatory, eso, vista

Galaxies, Stars and Nebulae series A great photo from deep space featuring the Dumbbell Nebula - also known as Messier 27 or NGC 6853. It's a typical planetary nebula and is located in the constellation Vulpecula (The Fox).

The distance is rather uncertain, but is believed to be around 1,200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects.

Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarefied gas that has been ejected from the hot central star (well visible on this photo), now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths.

This image is the beautiful by-product of a technical test of some FORS1 narrow-band optical interference filters. They only allow light in a small wavelength range to pass and are used to isolate emissions from particular atoms and ions.

In this three-colour composite, a short exposure was first made through a wide-band filter registering blue light from the nebula. It was then combined with exposures through two interference filters in the light of double-ionized oxygen atoms and atomic hydrogen. They were colour-coded as “blue”, “green” and “red”, respectively, and then combined to produce this picture that shows the structure of the nebula in “approximately true” colours.
