A home-brew observatory detects exoplanet

more »

David Schneider, a senior editor at IEEE Spectrum, was interested in exoplanets, planets that orbit stars other than the sun, but figured this kind of exercise as a home-based project was going to need expensive telescopes; he stumbled across a project at Ohio State University, where resourceful astronomers had figured out a way to spot exoplanets using a device with a lens designed for high-end cameras. Schneider's wheels turned, thinking he might also be able to pull this off if he got his hands on a charge-coupled-device detector not research-grade, and maybe he could forget about an expensive telescope as well? He also discovered an online posting by an amateur astronomer saying he had detected a known exoplanet using a digital single-lens reflex (DSLR) camera with a telephoto lens.

Ground-based detection of super-Earth transit paves way to remote sensing of exoplanets

more »

Astronomers have measured the passing of a super-Earth in front of a bright, nearby Sun-like star using a ground-based telescope for the first time. The transit of the exoplanet 55 Cancri e is the shallowest detected from the ground yet. Since detecting a transit is the first step in analyzing a planet's atmosphere, this success bodes well for characterizing the many small planets that upcoming space missions are expected to discover in the next few years.

Herschel observes Andromeda's past and future stars

more »

Recently, the infrared Herschel Space Observatory, has taken a series of beautiful high-resolution infrared images of Andromeda. It is the first time we can see M31, at these wavelengths, at such a high resolution. The quality and sensitivity of the Herschel data is so good scientists were able to study the properties of individual regions in Andromeda as small as about 400 light years.

CERN’s DG starts blogging for Huffington Post



Today, Rolf Heuer, CERN’s Director-General, published a blog post on Huffington Post . This is the first post in a series to be published in a blog for the online news aggregator. The idea of the blog stems from the International Geneva Perception Change project, which aims to put the spotlight back on the relevance and impact of the work done by all of the UN and international organizations, NGOs and other institutions based in Geneva. Heuer joins Michael Møller and other project members on the blog for Huffington Post.


The first post concerns the Chief Scientific Advisor role at the European Commission. The European Commission President’s recent decision not to renew the role of Chief Scientific Advisor shook the scientific community. Heuer addresses the media attention and concerns of the scientific community but remains cautiously optimistic.


“Scientific evidence is not an option in policy-making, it is a necessity. It is about evidence based decision making,” says Heuer. "As scientists, we must continue to encourage Juncker to keep science at the centre of policy, and I look forward to seeing how he proposes to achieve that”.

Hackers begone: Measurement-device-independent QKD increases clock rate and transmission distance while reducing failure

more »

(Phys.org)—In the ongoing effort to make communications secure, Quantum Key Distribution (QKD) theoretically provides a solution – but to the delight of increasingly sophisticated hackers, falls short in real-world systems due to implementation deviating from mathematical models. A number of QKD variants – including Device-Independent Quantum Key Distribution (DIQKD) and the more recently introduced Measurement-Device-Independent Quantum Key Distribution (MDIQKD) – attempt to close the gap between theory and practice with varying degrees of success. These two variants differ in several ways, the most important being that DIQKD requires but unlike MDIQKD cannot easily achieve very high detection efficiency and low channel loss to yield secure keys, while MDIQKD, unlike DIQKD, does not rely on any ideal devices and can close the most vulnerable QKD security hole by removing all side-channels from the measurement unit. Nevertheless, previous MDIQKD systems have had limitations as well, such as limited distance and a low key rate of less than 0.1 bit/s.

Monogram Barred Spiral Galaxy NGC 1672 Stickers

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


tagged with: monogram initials, star galaxies, deep space astronomy, barred spiral galaxy, bsgsst, starry space picture, galactic arms, supermassive black hole, dust lanes, star forming galaxy

Galaxies, Stars and Nebulae series This NASA Hubble Space Telescope view of the nearby barred spiral galaxy NGC 1672 unveils details in the galaxy's star-forming clouds and dark bands of interstellar dust.
One of the most striking features is the dust lanes that extend away from the nucleus and follow the inner edges of the galaxy's spiral arms. Clusters of hot young blue stars form along the spiral arms and ionize surrounding clouds of hydrogen gas that glow red. Delicate curtains of dust partially obscure and redden the light of the stars behind them by scattering blue light.
Galaxies lying behind NGC 1672 give the illusion they are embedded in the foreground galaxy, even though they are really much farther away. They also appear reddened as they shine through NGC 1672's dust. A few bright foreground stars inside our own Milky Way Galaxy appear in the image as bright and diamond-like objects.
As a prototypical barred spiral galaxy, NGC 1672 differs from normal spiral galaxies, in that the arms do not twist all the way into the center. Instead, they are attached to the two ends of a straight bar of stars enclosing the nucleus. Viewed nearly face on, NGC 1672 shows intense star formation regions especially off in the ends of its central bar.
Astronomers believe that barred spirals have a unique mechanism that channels gas from the disk inward towards the nucleus. This allows the bar portion of the galaxy to serve as an area of new star generation.
NGC 1672 is also classified as a Seyfert galaxy. Seyferts are a subset of galaxies with active nuclei. The energy output of these nuclei can sometimes outshine their host galaxies. This activity is powered by accretion onto supermassive black holes.
NGC 1672 is more than 60 million light-years away in the direction of the southern constellation Dorado. These observations of NGC 1672 were taken with Hubble's Advanced Camera for Surveys in August of 2005. The composite image was made by using filters that isolate light from the blue, green, and infrared portions of the spectrum, as well as emission from ionized hydrogen.

Monogram, Rings of Gas Giant Saturn - solar system Round Stickers

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


tagged with: monogram initials, star galaxies, astronomy pictures, strnmxtlt, outer space picture, hubble space image, rings of saturn, gas giant astronomy, solar system planet, ice particles, rocky debris, planetary bodies

Galaxies, Stars and Nebulae series A stunning image of Saturn, taken when the planet's rings were at their maximum tilt of 27 degrees toward Earth. Saturn experiences seasonal tilts away from and toward the Sun, much the same way Earth does. This happens over the course of its 29.5-year orbit. This means that approximately every 30 years, Earth observers can catch their best glimpse of Saturn's South Pole and the southern side of the planet's rings. Between March and April 2003, researchers took full advantage to study the gas giant at maximum tilt. They used NASA's Hubble Space Telescope to capture detailed images of Saturn's Southern Hemisphere and the southern face of its rings.
