    BUBBLE NEBULA

    Hubble’s snap of a majestic, giant cosmic soap bubble was selected to mark Hubble’s 26th year in space. This seven-light-year-wide bubble, also known as NGC 7635, can be found some 8,000 light years away in the constellation Cassiopeia.

    Within the bubble sits the massive, super-hot star SAO 20575, which is 45-times more massive than the Sun. Gas from the star – its stellar wind – escapes at speeds of over 6.4 million kilometres (4 million miles) per hour, providing the pressure to force the interstellar material outward, forming the bubble shape. The star is 4 million years old, and will explode in a spectacular supernova in roughly 10 to 20 million years.

    Did Venus Once Have A Moon?
    It’s long been established that Venus, like Mercury, does not have a moon. But does that mean the celestial body has always been entirely alone? Not quite. In 2002, a quasi-satellite was discovered by Brian A. Skiff at Lowell Observatory. Recently na
