The Dark Energy Camera, a $40-million piece of equipment that represents a pinnacle of astronomical research, is now peering into the reddest reaches of the universe from its new home in Chile, and has seen “first light,” said Joshua Frieman, director of the survey. “That’s a major milestone,” Frieman told the Los Angeles Times in…
The highest-resolution camera ever built has begun its quest to pin down the mysterious stuff that makes up nearly three-quarters of our Universe. The Dark Energy Survey’s 570-million-pixel camera will scan some 300 million galaxies in the coming five years. The goal is to discover the nature of dark energy, which is theorized to be…
A warp drive to achieve faster-than-light travel — a concept popularized in television’s Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light….
What knowledge of science, culture and civilization would you most want to pass on to the surviving humans as they faced the prospect of adapting to a new environment and rebuilding their lives over many generations?
Archaeologists have discovered eight extremely well-preserved spears that are an astonishing 300,000 years old, making them the oldest known weapons ever found. They probably belonged to members of the species homo heidelbergensis, although no human remains have yet been found at the site. Homo heidelbergensis lived throughout the Old World between 600,000 and 300,000 years…
The drought-induced run-up in corn prices is a reminder that we’re nowhere near solving the problem of feeding the world. The price surge, the third major international food price spike in the last five years, casts more doubt on the assumption that widespread economic development leads to corresponding gains in agriculture. The green revolution has…
A spacecraft orbiting Mars has detected carbon dioxide snow falling on the Red Planet, making Mars the only body in the solar system known to host this weird weather phenomenon. The snow on Mars fell from clouds around the planet’s south pole during the Martian winter spanning 2006 and 2007, with scientists discovering it only…
The answer to the enduring question of the smallest thing in the universe has evolved along with humanity. People once thought grains of sand were the building blocks of what we see around us. Then the atom was discovered, and it was thought indivisible, until it was split to reveal protons, neutrons and electrons inside….
NASA-funded astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. The findings offer the best evidence yet that planets can sprout up in dense stellar environments. Although the newfound planets are not habitable, their skies would be starrier than what we see from Earth. The starry-skied planets…
A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study reshapes the universal family tree, adding a fourth major branch to the three that most scientists agree represent the fundamental domains of life. The new findings…
