First light for SPHERE exoplanet imager: Revolutionary new VLT instrument installed

more »

SPHERE -- the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument -- has been installed on ESO's Very Large Telescope (VLT) at the Paranal Observatory in Chile and has achieved first light. This powerful new facility for finding and studying exoplanets uses multiple advanced techniques in combination. It offers dramatically better performance than existing instruments and has produced impressive views of dust discs around nearby stars and other targets during the very first days of observations.

Astronomers discover first Thorne-Zytkow object, a bizarre type of hybrid star

more »

In a discovery decades in the making, scientists have detected the first of a 'theoretical' class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Zytkow. Thorne-Zytkow objects are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelguese in the constellation Orion. They differ, however, in their distinct chemical signatures that result from unique activity in their stellar interiors.

NASA should maintain long-term focus on Mars as 'horizon goal' for human spaceflight

Arguing for a continuation of the nation's human space exploration program, a new congressionally mandated report from the National Research Council concludes that the expense of human spaceflight and the dangers to the astronauts involved can be justified only by the goal of putting humans on other worlds.

Light from huge explosion 12 billion years ago reaches Earth

more »

Intense light from the enormous explosion of a star 12.1 billion years ago -- shortly after the Big Bang -- recently reached Earth and was observed by a robotic telescope. Known as a gamma-ray burst, these rare, high-energy explosions are the catastrophic collapse of a star at the end of its life. Astronomers can analyze the observational data to draw further conclusions about the structure of the early universe.

Black hole 'batteries' keep blazars going and going

more »

Astronomers studying two classes of black-hole-powered galaxies have found evidence that they represent different sides of the same cosmic coin. By unraveling how these objects, called blazars, are distributed throughout the universe, the scientists suggest that apparently distinctive properties defining each class more likely reflect a change in the way the galaxies extract energy from their central black holes.

Astronomers discover two new worlds orbiting ancient star next door: One may be warm enough to have liquid water

more »

Astronomers have discovered two new planets orbiting a very old star that is near to our own sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life. Kapteyn's Star, named after the Dutch astronomer, Jacobus Kapteyn, who discovered it at the end of the 19th century, is the second fastest-moving star in the sky and belongs to the Galactic halo, an extended group of stars orbiting our Galaxy on very elliptical orbits. With a third of the mass of the Sun, this red-dwarf can be seen with an amateur telescope in the southern constellation of Pictor.

Accurate placement of molecules into gaps between gold nanoantennas enables ultrahigh-sensitivity molecular detection

more »

The ability to detect tiny quantities of molecules is important for chemical sensing as well as biological and medical diagnostics. In particular, some of the most challenging and advanced applications involve rare compounds for which only a few molecules may be present at a time. The most promising devices for achieving ultrahigh-precision detection are nanoscale sensors, where molecules are placed in tiny gaps between small gold plates. But this method is effective only if the molecules are positioned accurately within the gaps. Now, Jinghua Teng from the A*STAR Institute of Materials Research and Engineering, Singapore, and colleagues from the National University of Singapore have developed a sensor where molecules are efficiently guided and placed into position.

Carina Nebula in Argo Navis constellation Sticker

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

Carina Nebula in Argo Navis constellation Sticker

tagged with: stars, galaxies, astronomy, peel off, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, ngc 3372

Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

Leading scientists organize international workshop about DNA-based microchips

original post »

Dresden’s scientists are internationally renowned in the field of biomimetic material synthesis which uses biological principles such as molecular recognition and self-assembling for the tailor-made synthesis of new materials and structures. Therefore, the international workshop ‘DNA-Based Nanotechnology: Digital Chemistry (DNATEC14)’ hosted by the Max Planck Institute for the Physics of Complex Systems is well received within the global community. The workshop takes place from 5 to 9 May and is organized with the help of the Center for Advancing Electronics Dresden (cfaed) of TU Dresden and Kurt Schwabe Institute for Measure and Sensor Technology e.V. Meinsberg. “This promising future nanotechnology uses the genetic material carrier Deoxyribonucleic Acid (DNA) as a basic element for future electronic devices and sensors. We expect that the efficiency of the traditional silicon-based semiconductor technologies cannot be furthered in about ten years“, workshop coordinator Prof. Michael Mertig, also Leader of the cfaed research Path ’Biomolecular-Assembled Circuits’ (BAC), explains. “Hence, such innovative approaches are very interesting.” About one hundred scientists are expected to attend the conference. The lecturers visit from the USA, France, Denmark, Netherlands, India, Italy, Japan, UK, Israel, and Germany. Amongst them are Ned Seeman of New York University, the founder of the research area of
