The Spider and The Fly

Explanation: Bright clusters and nebulae abound in the ancient northern constellation of Auriga. The region includes the open star cluster M38, emission nebula IC 410 with Tadpoles, Auriga's own Flaming Star Nebula IC 405, and this interesting pair IC 417 (lower left) and NGC 1931. An imaginative eye toward the expansive IC 417 and diminutive NGC 1931 suggests a cosmic spider and fly. About 10,000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded in glowing hydrogen gas. For scale, the more compact NGC 1931 is about 10 light-years across.

OBJEK MISTERI HENTAM BUMI!!!

SYDNEY – Beberapa saintis kehilangan punca untuk mengenal pasti satu objek misteri yang bergerak amat laju semasa melintasi bumi kelmarin, lapor sebuah akhbar semalam.

Objek yang dinamakan 2010 AL30 itu cuma bersaiz antara 10 meter hingga 15 meter dan ia dipercayai tidak menyebabkan kemusnahan besar semasa menghentam bumi.

Ia turut dilihat oleh beberapa ahli astronomi di Amerika Syarikat (AS).

Dua saintis Itali, Ernesto Guido dan Giovanni Sostero berkata, objek tersebut mungkin sampah angkasa.

Ruang angkasa sekitar bumi dicemari berbilion-bilion sampah angkasa pelbagai saiz termasuk serpihan roket dan satelit sejak bekas Kesatuan Soviet melancarkan roket Sputnik One 53 tahun lalu.

Namun, seorang saintis Pentadbiran Aeronautik dan Angkasa Lepas Kebangsaan (NASA) menyatakan objek itu mungkin sebutir tahi bintang kecil berdasarkan laluan yang lebih hampir dengan planet Marikh dan Zuhal. – Agensi

Explanation: Beautiful island universe M94 lies a mere 15 million light-years distant in the northern constellation of the hunting dogs, Canes Venatici. A popular target for astronomers the brighter inner part of the face-on spiral galaxy is about 30,000 light-years across. Traditionally, deep images have been interpreted as showing M94's inner spiral region surrounded by a faint, broad ring of stars. But a new multi-wavelength investigation has revealed previously undetected spiral arms sweeping across the outskirts of the galaxy's disk, an outer disk actively engaged in star formation. At optical wavelengths, M94's outer spiral arms are followed in this remarkable discovery image, processed to enhance the outer disk structure. Background galaxies are visible through the faint outer arms, while the three spiky foreground stars are in our own Milky Way galaxy.
