Romantic Galaxies

Some 60 million light-years away in the southerly constellation Corvus, two large galaxies have collided. But stars in the two galaxies - NGC 4038 and NGC 4039 - don't collide in the course of the ponderous, billion year or so long event. Instead, their large clouds of molecular gas and dust do, triggering furious episodes of star formation. Spanning about 500 thousand light-years, this stunning view reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. Of course, the visual appearance of the far-flung arcing structures gives the galaxy pair its popular name - The Antennae. Recorded in this deep image of the region at the tip of the upper arc is a tidal dwarf galaxy NGC 4038S, formed in the cosmic debris.

these two galaxies are so beautiful!! they proove the power of space. out of prediction and sometimes phenomenal. dari sisi femininnya ci: romantis.. coz fotonya membentuk sebuah hati. uuu... cocok buat kartu ucapan untuk pacar. cantik, tapi gak klise =)

amazing black hole

Binary star system GRO J1655-40 consists of a relatively normal star about twice as massive as the Sun co-orbiting with a black hole of about seven solar masses. This striking artist's vision of the exotic binary system helps visualize matter drawn from the normal star by gravity and swirling toward the black hole. But it also includes a wind of material escaping from the black hole's accretion disk. In fact, astronomers now argue that Chandra Observatory x-ray data indicate a high-speed wind is being driven from this system's disk by magnetic forces. Internal magnetic fields also help drive material in the swirling disk into the black hole itself. If you had x-ray eyes as good as Chandra's, you could find GRO J1655-40 about 11,000 light-years away in the constellation Scorpius.

it is amazing, isnt it?
