On the evening of Thursday, 25 March 2010, the Moon and Mars will be in conjunction, a wonderful astronomical phenomenon, in which two or more celestial bodies are visible close together, near the line of sight. The Moon-Mars conjunction will be observable in the skies of Egypt and all the Arab countries. Mars, the Red Planet, will shine as a bright reddish star, near the Moon.

On 22 March 2010, the Solar System featured a magnificent alignment. Saturn, the ringed wonderful planet, was opposite to the Sun in the sky; this is an interesting astronomical phenomenon, termed opposition. To an observer looking on the Solar System, from a large distance, above the plane of Earth’s orbit, Saturn, Earth and the Sun were on a straight line; Earth was situated between the Sun and Saturn, the sixth planet.

On 27 January 2010, Mars will come to within nearly 100 million km from Earth, the shortest distance between the two planets, in 26 months. In the evening, Mars will shine as a brilliant reddish star, with a brightness similar to that of Sirius, the brightest naked-eye star. Mars is the second closest planet to Earth, following Venus, our “Twin Planet”, which comes to within about 38 million km from Earth, at its closest.

On the evening of Thursday, 31 December 2009, a partial lunar eclipse will be visible in the skies of Egypt. Lunar eclipses are among the most beautiful natural phenomena. They occur when the Moon passes through Earth’s shadow. Thursday’s lunar eclipse will begin at 19:17 EET, and will last over four hours. This eclipse is of small magnitude, as only a small portion of the Moon will be darkened, at maximum eclipse.

NASA recently published a stunning image of a Saturnian moon, acquired by the Saturn-bound Cassini spacecraft. The moon, known as Dione (1,120 km across), is visible as a slender crescent, as the spacecraft and the Sun were nearly on opposite sides of it. The outline of a crater is just visible in Dione’s southern hemisphere.

Every about 15 years, Earth crosses the plane of Saturn’s magnificent rings, and the rings turn edge-on, as viewed from Earth. Therefore, the extremely thin rings almost disappear! This rare cosmic alignment, termed ring plane crossing, provides an opportunity to study the structure of the rings and to discover new small moons of Saturn, particularly those that orbit close to, or within the rings.

NASA recently published spectacular images of Deimos, the smaller of the two tiny Martian moons. The enhanced-color images were acquired by the high-resolution camera (HiRISE), aboard NASA's Mars Reconnaissance Orbiter (MRO), on 21 February 2009.

Though galaxies are the most widely distributed objects in our immensely vast universe, they do collide. NASA’s Hubble Space Telescope (HST) has imaged numerous pairs of galaxies in collision. Each colliding pair is a different intriguing case. The above image shows one of the most spectacular galaxy encounters ever observed.
