Astronomy
is probably the oldest science. Ancient civilizations around the world
gazed up at the sky and the stars, but it wasn’t until the scientific
enlightenment of the 17th century that astronomers were able to get a
handle on how things actually worked up there. These new discoveries
would eventually lead to the rich, fascinating picture of the universe
we have today. Here are a few significant milestones that had to be
reached along the way.

First Telescope
The first patent for a telescope was applied for by a Dutch
eyeglasses manufacturer named Hans Lippershey. In 1608, he created a
device capable of producing 3x magnification. However, the invention of
the telescope, like all great technological breakthroughs, comes with
controversy.
It’s also the story of the invention of the microscope, as both
instruments were the same piece of technology at that point.
Lippershey’s town of Middelburg was also home to Hans and Zacharias
Janssen, a father and son lens-crafting team who claimed credit for the
invention and accused Lippershey of thievery. Another Dutch spectacle-maker, Jacob Metius of Alkmaar, filed a patent similar to Lippershey’s a few weeks later. The Dutch spectacle-makers were so busy arguing among themselves over who came up with the magnification device none of them actually did any astronomy with it. |

The
ultimate fate of the universe is a topic in physical cosmology. Most of
the cosmologists says that the ultimate fate of the universe is
dependent on the shape of the universe and what role dark energy will
play as the universe ages.
There are many theories, many ideas, many possible fates are
predicted by rival scientific theories. But could we actually predict
the future of the univers? This question arise another questions like: Do the past and future exist? what does that mean for quantum randomness? What is Random after all? …etc…. A list of scientific (even philosophical) questions that nobody have concret answers yet. Do not hesitate to tell us about your review (you can see down cosmosup-team’ review).

Talk
about heavy metal! This shiny, lumpy rock spotted by NASA’s Curiosity
rover is likely made mostly of iron—and came from outer space! It’s an
iron meteorite, similar to ones found in years past by Curiosity’s
forerunners Spirit and Opportunity, but is considerably larger than any
of the ones the MER rovers came across… in fact, at 2 meters (6.5 feet)
wide this may very well be the biggest meteorite ever discovered on Mars

The transmitted photograph from the Martian surface combines a
series of high-resolution circular images taken by the Remote
Micro-Imager (RMI) of Curiosity’s Chemistry and Camera (ChemCam)
instrument with color and context from rover’s Mast Camera (Mastcam).
Curiosity snapped the images during the 640th Martian day, or sol, of
Curiosity’s work on Mars – May 25, 2014 back here on Earth.
The imaging shows angular-shaped cavities on the surface of the rock.
One possible explanation is that they resulted from preferential
erosion along crystalline boundaries within the metal of the rock.
Another possibility is that these cavities once contained olivine crystals, which can be found in a rare type of stony-iron meteorites called pallasites, thought to have been formed near the core-mantle boundary within an asteroid.
