Time is eternal, but methods of tracking it are not -- and so a Johns Hopkins University astronomer wants to replace the Gregorian calendar, with its leap years and floating dates and 15th-century effluvia, with a sleek and standardized system for the world.
The city of Venice has long been valued for its unique character. Built in a lagoon along the coast of Italy, the scenic city is crisscrossed with canals. Its waterlogged nature draws a steady stream of visitors, but also makes it vulnerable to costly flooding. The region sometimes experiences unusually high tides, locally referred to as “acqua alta.”
Aristarchus, one of the brightest features on the moon’s surface, can easily be spotted with the naked eye. Going one better, NASA’s Lunar Reconnaissance Orbiter snapped this spectacular image as it swooped down to just 16 miles above the lunar surface.
For nearly 250 years, the intricate detail and complexity of skin's nervous-system wiring has thwarted attempts at understanding. But if researchers studying skin could be imagined as technicians reverse-engineering a supercomputer's peripherals, they'd have just traced about three lines back to the motherboard.
Astronomers weekly announce the discovery of new exoplanets, some similar in size or temperature to our own planet -- but Earth-like worlds are not always far away. Saturn's largest moon, Titan, boasts many familiar features.
NASA's Hubble Space Telescope has spotted a young star undergoing violent birth. The star, named S106 IR, has a mass of about 15 times that of our sun and lies approximately 2,000 light-years away in the constellation astronomers divide the sky into eighty-eight emconstellations/em with defined boundaries
Using a telescope that can see cold grains of cosmic dust, astronomers have photographed the freezing factories of the Milky Way galaxy's biggest stars.
If there is one thing to say about my own to-do lists, it is continuously expanding. For some reason they never get shorter but always longer. The more I am working or the more I am finding solutions new challenges seem to appear and only in the last weeks before the launch campaign I manage
A remote colony of birds kept flying away before anyone could count them, so a team of ecologists built a do-it-yourself aerial drone to spy on them from above.
The Mars Science Laboratory, the largest and most complex machine that has ever landed on another planet, is on target to launch on Nov. 25 at 7:25 a.m. PST.
