A little interesting about space life.

Judith E. Braffman-Miller is a writer and astronomer whose articles have been published since 1981 in various newspapers, journals, and magazines. Although she has written on a variety of topics, she particularly loves writing about astronomy because it gives her the opportunity to communicate to others the many wonders of her field. Her first book, "Wisps, Ashes, and Smoke," will be published soon.



and here is another

The true reason you can't see the stars in photos and videos of Moon is not that the stars aren't there, but rather because of the omnipresent sunlight and the exposure limits of cameras.



and finally

Titan circles its giant parent-planet once every 15 days and 22 hours. Like Earth's own large Moon, and a number of other moons dancing around the quartet of giant gaseous planets of our Solar System's outer realm, its rotation period is identical to its orbital period. This means that Titan is tidally locked in synchronous rotation with Saturn--always showing only one face to its planet.

Earth's Moon is the fifth largest moon in our entire Solar System, as well as the only world beyond our planet that we have visited. Our lunar companion is the largest and brightest object in the sky at night, and many astronomers think that it was born when the tragedy that was the pulverized Theia blasted into ancient Earth billions of years ago. There are other theories, however, that seek to explain how our Moon came to be. Nevertheless, the Giant Impact theory stands its ground as the most credible explanation for lunar birth. When the doomed, destroyed Theia impacted Earth, it shot debris above our planet. This abundant debris eventually coalesced to form our Moon.



The first observations of Mars as an object traveling in Earth's night sky was recorded by the ancient Egyptian astronomers, and by 1534 BCE the ancient astronomers were familiar with the retrograde movement of the planet. By the time of the Neo-Babylonian Empire, the Babylonian astronomers were making regular records of the positions of the planets, as well as systematic detections of their behavior. In the case of Mars, the ancient astronomers realized that it made 42 circuits of the zodiac every 79 years. These scientists of long ago even invented arithmetic methods so that they could make minor corrections pertaining to the predicted positions of the planets inhabiting our Solar System. The ancient astronomers referred to the planets as "wandering stars".



The current study's Franco-Belgian-Japanese collaboration looks forward to this mission. JAXA plans to enlist them to conduct tests on the Martian samples when they are returned to Earth. The samples will help the scientists determine whether Phobos is indeed made up of a mixture of Martian mantle and debris left in the wake of the tragic crash of the doomed, vanished protoplanet--as suggested by their supercomputer simulations.
