Hats off to the Grand Canyon!
Bored at work? Counting down the hours to the weekend?
Then Weird Science can help (as long as the boss doesn't spot ya!).
Weird Science Friday Links give you a nudge towards stuff you'll hopefully find more diverting than the stack of papers in front of you!
Evolution in action has been observed in snails by members of the public taking part in an online science project.
More than 6,000 people from 15 European countries took part in the Open University study, Evolution MegaLab, launched in April 2009 to mark the 200th anniversary of Charles Darwin's birth.
Participants were asked to report sightings of banded snails to the MegaLab project via a website address.
More than 7,600 new observations were made in 2009 which were added to historical data collected between 1950 and 1990.
This amazing video captured in February by NASA's Solar Dynamics Observatory shows how sunspots surface, change, and grow over time as the forces of both convection and the Sun's powerful magnetic field act upon them.
The time elapsed is about two weeks, or a half rotation of the Sun.
This spooky image shows the controversial cranium of Australopithecus sediba, unearthed in April 2010 in a South African cave.
Fossils of the bones of the young male and adult female suggests a controversial new species, that walked upright and shared many physical traits with the earliest known human Homo species.
The finding of the pre-human, or hominid, fossils - which scientists say are between 1.78 and 1.95 million years old - is believed to possibly answer some key questions about where humans came from.
Giant tortoises have rescued the ecology of a tropical island devastated by deforestation in a successful example of "rewilding".
British scientists brought the giant Aldabra tortoise, Aldabrachelys gigantea, to the Ile aux Aigrettes, off Mauritius, to help disperse ebony tree seeds.
Intensive logging that lasted until the early 1980s has decimated the ebony forest which once covered the 25-hectare island.
A field of radio dishes that look like giant dinner plates have waited for years in the mountains of Northern California for the first call from intelligent life among the stars.
But they are not listening any more because cash-strapped governments, it seems, can no longer pay the interstellar phone bill.
Astronomers at the SETI Institute said a steep drop in state and government funds has forced the shutdown of the Allen Telescope Array, a powerful tool in the search for extraterrestrial intelligence, an effort scientists refer to as SETI.
This image of two interacting galaxies, called Arp 273, has been released NASA in celebration of the 21st anniversary of the Hubble Space Telsescope's launch into space.
Gravitational forces have pulled the objects into the shape of a rose on a stem as seen from Earth's vantage point.
The jetpack dream is moving upward once again. Martin Aircraft, makers of the Martin Jetpack, have set a new flight duration record with their personal flight device, putting it in the air for seven solid minutes during a recent outdoor test.
At last, the future is nearly here!
