Eight-legged Gladiators

09 August 2007
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.


Sieving out cancer cells

09 August 2007
A microscopic sieve opens the way to earlier diagnosis of oral cancer, say US researchers.


A Stabbed Moon

08 August 2007
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.


Space Observatory Pictures a Massive Cosmic Collision

07 August 2007
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.


Hubble Pictures the Magnificent Remains of a Giant Star

06 August 2007
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.


New Clues to the Origin of a Saturnian Ring

05 August 2007
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.


Phoenix Blasts off toward Mars

04 August 2007
On 4 August 2007, NASA's Phoenix spacecraft lifted off on a mission to Mars, the Red Planet. Phoenix will land in the Martian arctic region to study the soil and ice.


An Infrared View of Saturn's Largest Moon

02 August 2007
NASA recently published an exquisite infrared image of Titan (5,150 km across), Saturn's largest moon. The image was acquired with the Saturn-bound Cassini spacecraft.


A Green Star

01 August 2007
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.


GOCE Satellite to Explore Earth's Gravity Field

31 July 2007
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.
