A new survey of one of the most active, star-forming regions in the galactic neighborhood is helping astronomers better understand the processes that may have contributed to the formation of the sun 4.5 billion years ago.
Astronomers using the Hubble Space Telescope have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies. This unique observation will help astronomers refine their estimates of the mass of dark matter in the lensing galaxy and cluster.
Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to research that proposes a new kind of engine for producing energy based on the Leidenfrost effect - a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point.
Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's 'suburbs'. It is located where astronomers have never spotted such a small cluster of stars before.
On 14 February 2015, the Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) on the Rosetta spacecraft observed the surface of comet 67P Churyumov-Gerasimenko with the Sun directly behind it, so the only shadow seen in the image is that of the photographer, the orbiter itself.
Astronomers have discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which could form planets.
An international team of researchers has demonstrated a way to assess the quality of water on Earth from space by using satellite technology that can visualise pollution levels otherwise invisible to the human eye through 'Superhero vision'.
Taking a simultaneously imaginative and rigidly scientific view, Cornell chemical engineers and astronomers offer a template for life that could thrive in a harsh, cold world - specifically Titan, the giant moon of Saturn.
