Most Earth-like worlds are yet to form

Earth came early to the party in the evolving universe, according to a new theoretical study. It concludes that only eight percent of potentially habitable planets have even formed yet. But many future civilizations may arise so late that by then, evidence for the Big Bang—the explosion-like event that gave birth to the universe—will have disappeared.

Scientists are planing for mission to push asteroid off-course

Scientists are planning a project to test the waters for what might someday be a mission needed to save the Earth-by pushing an asteroid off-course. The current mission just involves diverting a mini-asteroid-or more precisely, the moon of an asteroid, which is also an asteroid, just smaller. The idea is to shift ...

Findings almost confirms that liquid water flows on Mars

New findings from NASA's Mars Reconnaissance Orbiter satellite provide the strongest evidence yet that liquid water flows part of the time on Mars, scientists with the mission said. Using an instrument on the satellite called an imaging spectrometer, researchers detected signatures of minerals associated with water on slopes where mysterious streaks ...

Finally Rosetta satellite reveals commet's water-ice cycle

A daily cycle in which water ice turns to gas feeds the "tails" and fuzzy halos of comets like the one under scrutiny by the European Space Agency's Rosetta spacecraft, mission scientists say. Comets are mixtures of dust and ices, which they periodically shed as they swing towards their closest point ...

Fuck Spiderman: actual spider excels at thread-free air stunt

Creatures living high in the rainforest trees sometimes fall off the branches, perhaps as they're trying to escape a predator. But dropping down 30 meters (yards) or more can be dangerous. Not least is the risk of dropping onto unfamiliar ground where a new array of predators lurks. Scientists already know that ...

Harvard astronomers found 'runaway' galaxies

We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted what they call entire runaway galaxies. These islands of stars are leaving the galaxy clusters where they originally formed, having gained enough speed to overcome their gravitational ...

Study finds first stars were born "late"

New maps from the European Space Agency's Planck satellite show the first stars formed much later than previously thought, scientists say. The satellite maps so-called polarized light across the sky-light believed to have been traveling toward us since the almost dawn of time, and providing a certain view of the early ...

Star found to have little planets over twice as old as our own

Astronomers say they have found at least five smaller-than-Earth planets orbiting a star in a solar system over twice as old as our solar system. Although the planets are uninhabitable due to heat, the find suggests life could have formed long before our Earth formed, they add. The study shows that ...

NASA spacecraft, New Horizon is getting close to dwarf planets

NASA's Dawn spacecraft is closing in on the dwarf planet Ceres, agency scientists say-the first time a spacecraft is expected to visit a dwarf planet. A second such event is planned in July when another NASA craft, New Horizons, reaches Pluto, which was reclassified from planet to dwarf planet in 2006. Ceres, ...

Possible existence of wormhole in our galaxy

Our galaxy could conceivably be a huge wormhole - or shortcut through space and time - a study concludes, though this path may or may not be navigable. The study, published in the journal Annals of Physics, looks at a possibility that physicists had been toying with for some time and ...
