Crab spiders are fascinating creatures. They are highly camouflaged ambush hunters that prey on flower-visiting insects, such as bees, flies and butterflies. Exercising his favorite hobby of wildlife photography, BA Senior Astronomy Specialist, Aymen Ibrahem, recently recorded the clash of two small crab spiders.

NASA recently published an intriguing image of Dione, Saturn's icy moon. Dione (1,126 km across), which shines in the gibbous phase, is bisected by Saturn's wonderful rings, seen edge-on.

The clashing galaxies, pictured by NASA's Spitzer Space Telescope (SST), will ultimately merge, forming a gigantic galaxy up to 10 times as massive as our own Galaxy. This rare phenomenon provides an unprecedented insight into the formation mechanisms of the largest galaxies in the Universe.

NASA's Hubble Space Telescope (HST) imaged three portions of the Veil Nebula, the shattered remains of a massive star that exploded thousands of years ago. This series of images provides superbly detailed views of the delicate, wispy structure resulting from this cosmic explosion. The Veil Nebula is one of the most spectacular supernova (exploding star) remnants in the sky. The entire cloud spans about 3° on the sky, corresponding to about 6 full-moon breadths.

Analyzing data acquired by the Saturn-bound Cassini spacecraft, NASA scientists may have identified the source of an enigmatic Saturnian ring. Saturn's G ring is probably generated by relatively large, icy particles that reside within a bright arc on the ring's inner edge.

The green flash is a rare, fascinating sunset phenomenon. It may be observed when the Sun sinks into the sea. The last shard of the Sun disk turns green for a second or less, before it disappears. Mr. Aymen Ibrahem, BA Senior Astronomy Specialist, made a recent observation of the green flash effect in Alexandria.

In spring 2008, the European Space Agency (ESA) will launch a mission dedicated to measuring Earth’s gravity field and modeling the geoid with extremely high accuracy and spatial resolution. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is the first Earth Explorer Core mission to be developed as part of ESA’s Living Planet Programme.
