A star explodes Timelapse by Hubble Telescope made in 4 years!Monocerotis 2002 2006 1080p - Video

A haunting landscape of star systems, bubbles, and shock fronts lies toward the constellation of Taurus in an amazing photo taken by the Hubble Space Telescope.

Perhaps the most striking feature of the Hubble Space Telescopeviewis an apparent star embedded within a rust-colored cloud, toward the upper left corner. Although the bright spot, better known as XZ Tauri, appears to be a single star, it's actually a binary star system with one of those two stars also a binary system, making a total of three stars within a single system. The cosmic objects are located about 450 light-years from Earth.

A hot bubble of gas can be seen as the small orange lobe very close to the top left of XZ Tauri. It's speeding out from the star system, leaving an imprint spanning tens of billions of kilometers. As the gas travels, it hits slower moving material, and the shock of impact triggers pulses of light.

A similar phenomenon is occurring above and to the right of XZ Tauri, where wisps of deep red can be seen embedded within the blue clumps. The bright blue patch contains a young star known as HL Tauri. When narrow gas streams from the newborn star hit an interstellar cloud, the shock of impact lights up the target, a sight better known as a Herbig-Haro (HH) object, according to a Hubble mission statement.

In the bottom right of this Hubble image is another Herbig-Haro object known as HH 30. Although the source is hidden from view, its reflected light and prominent, knotty jets can be seen blasting out into space.

A version of this image won third prize in the Hubble's Hidden Treasures image processing competition.

Haunting Space Bubbles Shine in Amazing Hubble Telescope Photo

An image captured by the Hubble telescope shows a galaxy in the process of being devoured by a bigger galaxy nearby.

Just because space is (theoretically) infinite, that doesn't mean everything out there is neatly spaced. Things collide, from tiny objects smashing into other tiny objects, to objects on the galactic scale -- quite literally.

Spiral galaxy NGC 7714, roughly 100 million light-years from Earth, is one of those galaxies for which crowding is proving a dramatically brutal affair: it has drifted a little too close to nearby smaller galaxy NGC 7715, and is taking its time cannibalising its neighbour, as seen in a new photo snapped by the Hubble Space Telescope.

Sometime between 100 million and 200 million years ago, the two galaxies reached a close enough distance from each other to start disrupting each other's shapes -- evidenced by the peculiarity of NGC 7714.

Unlike a normal spiral galaxy, its arms have stretched out and a smoky golden haze extends from the core.

Additionally, a ring and two long trails of stars have stretched towards NCG 7714 -- forming a sort of bridge between the two galaxies. That bridge funnels material from NGC 7715 to the larger NGC 7714 and feeds star formation in NGC 7714, most of which is occurring at its core, although the entire galaxy is active.

A large number of these new stars are what are known as Wolf-Rayet stars. These are stars that, when they are young, are massive -- at least 20 solar masses each. They are very hot, with surface temperatures ranging between 30,000 and 200,000 Kelvin (the Sun's surface temperature is around 5,778 Kelvin) and very luminous, shining with tens of thousands to several million times the luminosity of the sun (although most of that output is in the ultraviolet spectrum).

Wolf-Rayet stars are the "live fast, die young" stage in the evolution of massive stars. Although they burn very hot and bright, they also lose mass at an accelerated rate, about a billion times higher than the sun's rate, due to very strong solar winds. Eventually the star runs out of material, and ends its life in a dramatic supernova.

Because of this star formation, NGC 7714 has been classified as a Wolf-Rayet starburst galaxy.
