Observing the birth of a planet

Astronomers have confirmed the existence of a young giant gas planet still embedded in the midst of the disk of gas and dust surrounding its parent star. For the first time, scientists are able to directly study the formation of a planet at a very early stage.

Rosetta spacecraft sees sinkholes on comet

more »
The European Space Agency's Rosetta spacecraft first began orbiting comet 67P/Churyumov-Gerasimenko in August 2014. Almost immediately, scientists began to wonder about several surprisingly deep, almost perfectly circular pits on the comet's surface. Now, a new study based on close-up imagery taken by Rosetta suggests that these pits are sinkholes, formed when ices beneath the comet's surface sublimate, or turn directly to gas.

Comet sinkholes generate jets

more »

A number of the dust jets emerging from Rosetta’s comet can be traced back to active pits that were likely formed by a sudden collapse of the surface. These ‘sinkholes’ are providing a glimpse at the chaotic and diverse interior of the comet.

Experience the Gravity of a Super Earth HD 40307g Print

Here's a great poster featuring a beautiful image from deep space

Twice as big in volume as the Earth, HD 40307g straddles the line between "Super-Earth" and "mini-Neptune" and scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. One thing is certain though: at eight time the Earth's mass, its gravitational pull is much, much stronger.

Australia slashes its renewable energy target by nearly 20%

Science Focus

original post »

Today, the Australian government drastically scaled back its renewable energy targets for 2020, dropping them by nearly 20 percent. The new target, 33 TeraWatt-Hours, ends an extended period of uncertainty. The Abbot government had announced its intent to lower the target, but parliamentary negotiations were required to set a new one.

Australia's initial target, 41 TW-hr, had been set in 2009 with the goal of having renewables contribute 20 percent of the nation's electrical generation. But greater efficiency and reduced manufacturing has already pushed the fraction of renewables up over 13 percent. The Abbott government, which is generally hostile to climate science, didn't feel the need to overshoot its goals and so decided to cut the renewable energy target.

Solar and biomass generation, two leading sources of renewable energy in Australia, will not be affected by the deal. But wind power was singled out for added scrutiny. The deal would see a new wind power commissioner appointed to hear public complaints and create a scientific committee that would look into the environmental and health impacts of turbines. As the Sydney Morning Herald notes, however, Australia's National Health and Medical Research Council "has found no convincing evidence of health effects associated with so-called 'wind turbine syndrome,'" although more research may be needed to reassure the public.

Monogram - Emission Nebula NGC 2467 in Puppis Classic Round Sticker

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


tagged with: envelope sealers, galaxies and stars, sculptured gas clouds, enebicp, constellation puppis, ngc 2467, the stern, hot young stars, star incubator, monogram initials

Galaxies, Stars and Nebulae series A colourful star-forming region is featured in this stunning image of NGC 2467 located in the southern constellation of Puppis (The Stern). Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing gas. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas, mostly hydrogen, that serves as an incubator for new stars. Some of these youthful stars have emerged from the dense clouds where they were born and now shine brightly, hot and blue in this picture, but many others remain hidden.

NGC 2367: Buried in the heart of a giant

This rich view of an array of colorful stars and gas was captured by the Wide Field Imager camera, on the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. It shows a young open cluster of stars known as NGC 2367, an infant stellar grouping that lies at the center of an immense and ancient structure on the margins of the Milky Way.

Monogram, Witch Head Nebula deep space image Classic Round Sticker

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


tagged with: monogram initials, star galaxies, outer space picture, deep space astronomy, witch head nebula, cursing witch, nasa space photograph, faces in space, witches curse, hrbstslr wtchneb, screaming witch

Galaxies, Stars and Nebulae series A witch appears to be screaming out into space in this image from NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE's detectors.
The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.
WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned.
