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 back [...]
BEAM, the new expandable module attached to the International Space Station, was opened up today for tests and equipment checks. The Expedition 49 crew also explored eating right in space, adapting to new technology and studied a variety of other life science and physics research.
Flight Engineer Kate Rubins opened up and entered the Bigelow Expandable Activity Module this afternoon. She temporarily installed gear inside BEAM for a test to measure the loads and vibrations the module experienc [...]
The first of its kind to be found outside the Milky Way.
A hot and dense mass of complex molecules, cocooning a newborn star, has been discovered by a Japanese team of 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 tantalising hint that the chemistry taking place across the Universe could be much more diverse than expec [...]
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.
The findings come from the rover's Sample Analysis at Mars, or SAM, instrument suite, which studied the gases xenon and krypton in Mars' atmosphere. The two gases can be used as tracers to help scientists investig [...]
The Five-hundred-meter Aperture Spherical Telescope (FAST) is nestled within a natural basin in China's remote and mountainous southwestern Guizhou province. Nicknamed Tianyan, or the Eye of Heaven, the new radio telescope is seen in this photograph taken near the start of its testing phase of operations on September 25. Designed with an active surface for pointing and focusing, its enormous dish antenna is constructed with 4,450 individual triangular-shaped panels.
The 500 meter physical dia [...]
The three Expedition 49 crew members measured noise levels on the International Space Station today and continued exploring how physical and organic phenomena are affected by weightlessness.
NASA astronaut Kate Rubins surveyed the acoustic environment inside the station today. She analyzed the sound levels of various life support gear and took standard measurements in the Destiny lab module and the Zvezda service module. Rubins also partnered up with Japanese astronaut Takuya Onishi to remix, [...]
