A Five Planet Dawn
more »
As January closes and in the coming days of February, early morning risers can spot the five naked-eye planets before dawn. Though some might claim to see six planets, in this seaside panoramic view all five celestial wanderers were found above the horizon along with a bright waning gibbous Moon on January 27. Nearly aligned along the plane of the ecliptic, but not along a line with the Sun, the five planets are spread well over 100 degrees across the sky. Just arriving on the predawn scene, fleeting Mercury stands above the southeastern horizon in the golden light of the approaching sunrise.

Hidden Galaxy IC 342
more »
Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed by intervening cosmic clouds, this deep telescopic image traces the galaxy's obscuring dust, blue star clusters, and glowing pink star forming regions along spiral arms that wind far from the galaxy's core. IC 342 may have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced the evolution of the local group of galaxies and the Milky Way.

New Hubble telescope observations suggest that a high-velocity gas cloud was launched from the outer regions of our own galaxy around 70 million years ago. Now, the cloud is on a return collision course and is expected to plow into the Milky Way's disk in about 30 million years. Astronomers believe it will ignite a spectacular burst of star formation then.

Putting silicon 'sawdust' in a graphene cage boosts battery performance

Scientists have been trying for years to make a practical lithium-ion battery anode out of silicon, which could store 10 times more energy per charge than today's commercial anodes and make high-performance batteries a lot smaller and lighter. But two major problems have stood in the way: Silicon particles swell, crack and shatter during battery charging, and they react with the battery electrolyte to form a coating that saps their performance.

Monstrous Cloud Boomerangs Back to Our Galaxy
Get larger image formats
The old adage "what goes up must come down" even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy. First discovered in the 1960s, the comet-shaped cloud is 11,000 light-years long and 2,500 light-years across. If the cloud could be seen in visible light, it would span the sky with an apparent diameter 30 times greater than the size of the full moon. The cloud, which is invisible at optical wavelengths, is plummeting toward our galaxy at nearly 700,000 miles per hour. Hubble was used to measure the chemical composition of the cloud as a means of assessing where it came from. Hubble astronomers were surprised to find that the cloud, which is largely composed of hydrogen, also has heavier elements that could only come from stars. This means the cloud came from the star-rich disk of our galaxy. The Smith Cloud is following a ballistic trajectory and will plow back into the Milky Way's disk in about 30 million years. When it does, astronomers believe it will ignite a spectacular burst of star formation, perhaps providing enough gas to make 2 million suns.
Please join the scientists in a live discussion about the origin and conclusions of this research during the Hubble Hangout at 3pm EST today (Thurs., Jan. 28, 2016): http://hbbl.us/Baq .

Scientists have gathered tiny fungi that take shelter in Antarctic rocks and sent them to the International Space Station. After 18 months on board in conditions similar to those on Mars, more than 60 percent of their cells remained intact, with stable DNA. The results provide new information for the search for life on the red planet. Lichens from the Sierra de Gredos (Spain) and the Alps (Austria) also traveled into space for the same experiment.

Elliptical M60, Spiral NGC 4647
more »
Giant elliptical galaxy M60 and spiral galaxy NGC 4647 do look like an odd couple in this sharp cosmic portrait from the Hubble Space Telescope. But they are found in a region of space where galaxies tend to gather, on the eastern side of the nearby Virgo Galaxy Cluster. About 54 million light-years distant, bright M60's simpler egg-like shape is created by its randomly swarming older stars, while NGC 4647's young blue stars, gas and dust are organized into winding arms rotating in a flattened disk. Spiral NGC 4647 is estimated to be more distant than M60, some 63 million light-years away. Also known as Arp 116, the pair of galaxies may be on the verge of a significant gravitational encounter, though. M60 (aka NGC 4649) is about 120,000 light-years across. The smaller NGC 4647 spans around 90,000 light-years, about the size of our own Milky Way.

Stellar parenting: Making new stars by 'adopting' stray cosmic gases

Astronomers have for the first time found young populations of stars within globular clusters that have apparently developed courtesy of star-forming gas flowing in from outside of the clusters themselves. This method stands in contrast to the conventional idea of the clusters' initial stars shedding gas as they age in order to spark future rounds of star birth.

According to Albert Einstein's theory of relativity, all bodies in a vacuum regardless of their properties are accelerated by the Earth's gravity at the same rate. This principle of equivalence applies to stones, feathers and atoms alike. Under the conditions of microgravity very long and precise measurements can be carried out to determine whether different atoms of different mass actually "fall equally fast".

New method proposed to probe the beginning of the universe

How did the universe begin? And what came before the Big Bang? Cosmologists have asked these questions ever since discovering that our universe is expanding. The answers aren't easy to determine. The beginning of the cosmos is cloaked and hidden from the view of our most powerful telescopes. Yet observations we make today can give clues to the universe's origin. New research suggests a novel way of probing the beginning of space and time to determine which of the competing theories is correct.

Graphenea increases capacity, reduces prices
more »
via Graphenea
Graphenea announces reduced prices on products and increased production capacity in 2016. Improving the material quality of staple products remains a key strategy for Graphenea, alongside limited strategic expansion of the product offering.
Improvements in process productivity will lead to reduced graphene prices this year. In particular, the price of CVD graphene film will decrease in all categories by 23% on average this year, as the company intends to provide a very competitive offer on all substrates and sizes to support their customers’ research. The price of the popular 4-pack of Monolayer Graphene on SiO2/Si (10mm x 10mm) already went down to $149 (139€). Notably, prices of graphene on custom substrates will decrease by 27%, making it easier for researchers to work on their own substrate. The price of graphene oxide (GO) for research will decrease by 33% on average. GO suspension will now be available in a 5-liter package, for only 28.55 USD per gram.
The addition of select new products to fulfill the evolving graphene market was part of the strategy in 2015. Most notably, the company introduced suspended monolayer graphene on cavities as a standard catalog product. In 2016, the company plans to introduce monolayer graphene on copper coated with PMMA as a standard product.
Apart from constant improvement of material quality and sustainable expansion of the product offering, Graphenea has been working on increasing production capacity. By the end of the year, the company expects to raise capacity to 1 tn/year of GO for industrial applications. This capacity will allow Graphenea to seek customers that are looking forward to increase their demand and to advance commercialization of graphene higher up the value chain.
By progressive reduction of prices on staple products, new materials and expanded capacity, Graphenea remains a key provider for scientific researchers and industrial partners alike.
Key highlights:
- Reduced prices
- Introducing monolayer graphene on copper with PMMA coating as standard
- Introducing 5-liter package of GO as standard
- Increasing production capacity to match industrial needs
About Graphenea:
Graphenea, headquartered at the nanotechnology cluster CIC nanoGune in San Sebastian, Spain, was established in 2010, and has since grown to be one of the world's largest providers of graphene. Graphenea employs 12 people and exports graphene materials to more than 370 customers in 53 countries. The company has focused on constant improvement of graphene quality, becoming a supplier customers can rely on. Graphenea employs a team of skilled laboratory staff who have brought graphene film production techniques to a new level, offering the same high quality films on any substrate. Following the demands of the growing industry, Graphenea also produces graphene oxide in volumes up to 5 liters per package. Graphenea partners with large multinationals to develop custom graphene materials for their applications. Its research agility and ability to keep pace with the progress of graphene science and technology has allowed Graphenea to become the largest graphene supplier in the Graphene Flagship, a ten year project of the European Commission worth a billion euros. The company keeps a close relation with the world's leading scientists, regularly publishing scientific articles of the highest level.
