Moonset at Whitby Abbey
more »
October's Hunters Moon shines near the horizon, setting beyond the arches of Whitby Abbey in this eerie night scene. The moonlight partly illuminates the ruined Benedictine abbey's grounds and walls on a cliff overlooking the North Sea from England's Yorkshire coast. Fans of Bram Stoker's 1897 novel Dracula will recognize the abbey and town of Whitby as the location of the Transylvanian count's shipwrecked landing on English shores. There fiction's most famous vampire transformed into an immense dog, jumped ashore and ran up the cliff to the ruined abbey. A 360 degree panorama, the dramatic fisheye view was created from 23 digitally stitched photos. Tomorrow's picture: ghost head nebula

Astronomers have discovered a batch of rapidly spinning stars that produce X-rays at more than 100 times the peak levels ever seen from the sun. The stars, which spin so fast they've been squashed into pumpkin-like shapes, are thought to be the result of close binary systems where two sun-like stars merge.

Forging a brand-new chemical bond using the pressure of the Mars core

When it comes to making chemical bonds, some elements go together like peanut butter and jelly; but for others, it's more like oil and water. Scientists can combat this elemental antipathy using extreme pressures. And now in a new article, researchers report that they have used pressure equivalent to that within the core of Mars to forge the first-ever iron-bismuth bond, which could help them make brand-new magnetic and superconducting materials.

A Death Star's Ghostly Glow
Get larger image formats
In writer Edgar Allan Poe's short story "The Tell-Tale Heart," a killer confesses his crime after he thinks he hears the beating of his victim's heart. The heartbeat turns out to be an illusion. Astronomers, however, discovered a real "tell-tale heart" in space, 6,500 light-years from Earth. The "heart" is the crushed core of a long-dead star, called a neutron star, which exploded as a supernova and is now still beating with rhythmic precision. Evidence of its heartbeat are rapid-fire, lighthouse-like pulses of energy from the fast-spinning neutron star. The stellar relic is embedded in the center of the Crab Nebula, the expanding, tattered remains of the doomed star.

A Giant Squid in the Flying Bat
more »
Very faint but also very large on planet Earth's sky, a giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this cosmic scene toward the royal constellation Cepheus. Composed with almost 17 hours of narrowband image data, the telescopic field of view is 4 degrees or 8 Full Moons across. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's alluring bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, Ou4 would represent a spectacular outflow driven by HR8119, a triple system of hot, massive stars seen near the center of the nebula. The truly giant Squid Nebula would physically be nearly 50 light-years across. Tomorrow's picture: haunting Cepheus

via Graphenea
Graphenea is proud to participate in a new project funded by EPSRC (the Engineering and Physical Sciences Research Council), the UK's main agency for funding research in engineering and the physical sciences. The project “2D Materials for Next Generation Healthcare Technologies” (2D-Health) started on October 1 st and will utilize £5.2m of funding over the next 5 years. The project aims to further explore how two-dimensional materials can improve major health challenges, such as cancer, diabetes and dementia. 2D-Health is one of four major research grants awarded as part of the EPSRC Healthcare Technologies scheme, totaling £17.7 million, that will develop new technologies to address the health issues of an aging UK population.
Graphenea is one of two graphene material producers in the project consortium. Other partners include four major healthcare multinationals and laboratories from across the University of Manchester, spanning physics, chemistry, pharmacy and medicine research.
2D-Health will utilize selected unique properties offered by 2D materials and technologies and develop innovative solutions for specific unmet clinical needs in wound care and management (relevant to diabetes), tissue rehabilitation by electrical stimulation (relevant to dementia), cell therapeutics (relevant to cardiovascular disease), and immunotherapeutics (relevant to cancer).
Research into using graphene for health is widespread, including graphene for drug delivery, biosensing, and getting rid of bacteria.
This programme directly aligns to the EPSRC Healthcare Technologies priorities by aiming to develop future therapies in specific applications of unmet clinical needs and draws on several cross-cutting capabilities: a) custom-design 2D materials into advanced materials under specifications aimed at a precise industry-driven use, exploring different chemical modification strategies; b) development of novel imaging and sensing technologies for tracking and monitoring therapeutic intervention; and c) develop 2D-based technologies through the preclinical stage for each of the application areas using relevant cellular and animal models. Strong industrial-academic partnership for rapid clinical translation, in collaboration with ethicists and regulators, aims to ensure responsible and societally-acceptable innovations.
Graphenea will participate with our extensive experience in graphene applications and with high quality materials.

The universe is expanding at an accelerating rate, or is it?
more »
Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery that the universe is expanding at an accelerating pace. This led to the widespread acceptance of the idea that the universe is dominated by a mysterious substance named 'dark energy' that drives this accelerating expansion. Now, a team of scientists has cast doubt on this standard cosmological concept. The evidence for acceleration may be flimsier than previously thought, they say, with the data being consistent with a constant rate of expansion.

Afforded by the mountaintop vantage point, the clear, long sight-line passes through layers of atmosphere. The changing atmospheric refraction shifts and distorts the otherwise steady apparent paths of the stars as they set.

Full Moon in Mountain Shadow

On October 15, standing near the summit of Hawaii's Mauna Kea and looking away from a gorgeous sunset produced this magnificent snapshot of a Full Moon rising within the volcanic mountain's shadow. An alignment across the Solar System is captured in the stunning scene and seeming contradiction of bright Moon in dark shadow. The triangular appearance of a shadow cast by a mountain's irregular profile is normal. It's created by the perspective of the distant mountaintop view through the dense atmosphere. Rising as the Sun sets, the antisolar point or the point opposite the Sun is close to the perspective's vanishing point near the mountain shadow's peak. But extending in the antisolar direction, Earth's conical shadow is only a few lunar diameter's wide at the distance of the Moon. So October's Full Hunters Moon is still reflecting sunlight, seen through the mountain's atmospheric shadow but found too far from the antisolar point and the Earth's extended shadow to be eclipsed.

Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the visible light emission from the Tulip Nebula.

Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the visible light emission from the Tulip Nebula. HDE 227018 is the bright star very near the blue arc at the center of the cosmic tulip. < | Archive | Submissions | Search | Calendar | RSS | Education | About APOD | Discuss | >

Ups and downs of water escape from Mars
more »
After investigating the upper atmosphere of the Red Planet for a full Martian year, NASA's MAVEN mission has determined that the escaping water does not always go gently into space. Hydrogen in Mars' upper atmosphere comes from water vapor in the lower atmosphere. An atmospheric water molecule can be broken apart by sunlight, releasing the two hydrogen atoms from the oxygen atom that they had been bound to. Several processes at work in Mars' upper atmosphere may then act on the hydrogen, leading to its escape.

Possible clouds on Pluto, next target is reddish
more »
Stern said that Pluto's complex, layered atmosphere is hazy and appears to be mostly free of clouds, but the team has spied a handful of potential clouds in images taken with New Horizons' cameras. "If there are clouds, it would mean the weather on Pluto is even more complex than we imagined," Stern said.

Eta Carinae: VLT Interferometer captures raging winds in famous massive stellar system
more »
Astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved. They found new and unexpected structures within the binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding. These new insights into this enigmatic star system could lead to a better understanding of the evolution of very massive stars.
