Lynds Dark Nebula 1251
more »
Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region, drifting above the plane of our Milky Way galaxy. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects seen in this sharp image. Distant background galaxies also lurk on the scene, visually buried behind the dusty expanse. The deep telescopic field of view spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251. Tomorrow's picture: light-weekend

NASA's Fermi finds record-breaking binary in galaxy next door
more »
Scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of gamma rays, the highest-energy form of light.

Rosetta instrument provided first-ever ultraviolet observations of a comet
more »
After a two-year orbital tour around comet 67P/Churyumov-Gerasimenko, ESA's Rosetta spacecraft -- carrying the Alice ultraviolet spectrograph -- will end its mission on Sept. 30. Rosetta is the first spacecraft to orbit and escort a comet, and Alice, developed and operated for NASA, is the first instrument to obtain far-ultraviolet observations at a comet.

Spiral arms in protoplanetary disk: They're not just for galaxies any more
more »
Astronomers have found distinct spiral arms in the disk of gas and dust surrounding the young star Elias 2-27. While similar features have been observed on the surfaces of such disks before, this is the first time they have been identified within the disk, where planet formation takes place. Structures such as these could either indicate the presence of a newly formed planet, or else create the necessary conditions for a planet to form. As such, the results are a crucial step towards a better understanding how planetary systems like our Solar system came into being.

Curiosity finds evidence of Mars crust contributing to atmosphere

NASA's Curiosity rover has found evidence that chemistry in the surface material on Mars contributed dynamically to the makeup of its atmosphere over time. It's another clue that the history of the Red Planet's atmosphere is more complex and interesting than a simple legacy of loss.

ALMA catches stellar cocoon with curious chemistry: First of its kind to be found outside the Milky Way
more »
A hot and dense mass of complex molecules, cocooning a newborn star, has been discovered astronomers using ALMA. This unique hot molecular core is the first of its kind to have been detected outside the Milky Way galaxy. It has a very different molecular composition from similar objects in our own galaxy -- a tantalizing hint that the chemistry taking place across the Universe could be much more diverse than expected.

Rosetta may be crashing, but its legacy lives on here on Earth
more »
ESA's Rosetta spacecraft arrived at Comet 67P/Churyumov-Gerasimenko on 6 August 2014, following a ten-year journey through the Solar System after its launch on 2 March 2004. The Philae lander was sent down to the surface of the comet on 12 November 2014. Confirmation of the end of mission is expected from ESA's main control room at 11:20 GMT or 13:20 CEST +/- 20 minutes on 30 September, with the spacecraft set on a collision course with the comet the evening before.

'Incomprehensible' birth of supercrystal explained
more »
Two years ago, a research team published an article explaining how they had created a material with unique and extremely interesting electronic characteristics. In this 'supercrystal', the electrons move almost with the speed of photons, and the electric current can be switched on and off. This makes it ideal for ultra-fast electronics. But at the time, the researchers were at a loss to explain how this 'supercrystal' obtained its unique structure. Now they have unraveled the mystery, and it appears to involve a completely different mechanism for crystal formation.
