What does a martian sunrise sound like? Now you can find out, as researchers have “sonified” (or turned into sound) an image of the Opportunity rover’s 5,000th sunrise on Mars. The data have been used to create a unique, two-minute piece of music, titled “Mars Soundscapes” — check it out below:

To turn the photo into sound, researchers scanned across the image from left to right. They combined brightness and color from each individual pixel ...read more
The Ant 2 “ghost” galaxy is a large, dim dwarf galaxy that scientists have discovered near the edge of the Milky Way. While low in mass, Ant 2 is about the same size as the Large Magellanic Cloud (LMC). (Credit: V. Belokurov and A. Smith (Cambridge, UK and CCA, New York, US) based on the images by Marcus and Gail Davies and Robert Gendler)
An international team of astronomers can’t fully explain the “ghost” galaxy that they discovered about 130 ...read more

A group of community members living in the Brazilian Amazon have created biodiversity hotspots by working to protect a single species, the giant South American river turtle. That’s according to a new study out Tuesday. The finding showcases the power of local conservation efforts, particularly in places that lack financial resources, ...read more

As alliances go, the one that exists between ants and plants is impressively robust. Symbiotic relationships exist between many species of flora and Formicidae fauna, and it’s evolved past simple you scratch my back, I’ll scratch yours deals. Some plants have been living and working with ants for so ...read more
“First Man” gave us a look at a side of Neil Armstrong we don’t see too often, focusing on the family side of his life over the science element, but even that only gave us a glimpse of the behind-the-scenes home and family life of the notoriously stoic first man on the Moon. Now, the brand new Armstrong-Engel Family Gallery has published personal, never-before-seen images of Neil and his family beginning in 1955 during his Edwards days gong all the way to 1969 and the Moon land ...read more
About 200,000 light-years from Earth, the SMC is a dwarf galaxy only about 7,000 light-years in diameter. This radio image shows hydrogen gas in the SMC, which is losing such gas at a higher rate than it is currently forming stars. (Credit: Naomi McClure-Griffiths et al, CSIRO’s ASKAP telescope)
Just as each successive smartphone companies release includes a higher-resolution camera for sharper, more detailed photos, each new instrument astronomers build reveals the universe in ever-fine ...read more
Life on Mars: One of the scientists spies on a new commercial drilling site in Season 2. (Credit: National Geographic/Richard Donnelly)
Mars the planet is a unique world: a little like Earth, a little like the Moon, but entirely a world unto itself. Mars the television show is similarly one of a kind, an unusual amalgam of scripted science fiction and serious science documentary. The fictional part of the story begins in 2033, when the spacecraft Daedalus lands on the Red Planet to establish t ...read more
Fast-moving monopoles likewise pump out this light, and so do the comparatively massive, slowpoke monopoles — but for a different reason. These monopoles, borne of the early Grand Unified era of the Big Bang when three of the fundamental forces were joined as one, would possess a vestige of the extreme energy density where the differences between Standard Model particles and forces disappear. “The Grand Unified monopole contains in its tiny heart a little bit of the Big Bang, when al ...read more
The richest countries use as much as 16 times more antibiotics, like Amoxicillin, than poor countries. (Credit: PureRadiancePhoto)
The World Health Organization (WHO) released a new report Monday that finds large disparities in antibiotic consumption worldwide. Consumption rates documented in the report vary by as much as 16 times between countries. The discovery suggests some countries are likely overprescribing whereas others may not have appropriate access to the medicines.
“Overuse a ...read more
