When galaxies collide, stars seldom crash into each other because they are still separated by enormous distances. But as this Hubble Space Telescope view of NGC 3256 shows, gas and dust in colliding galaxies can come together with spectacular consequences, triggering the formation of vast numbers of new stars and clusters. NGC 3256, located about 100 million light-years from Earth in the constellation of Vela, is the result of the collision of two Milky Way-size galaxies that began about 500 million years ago. It is now an especially luminous starburst galaxy oriented face-on to Earth and showing two distinct nuclei, one of them shrouded by gas and dust, surrounded by more than 1,000 bright star clusters embedded in crisscrossing dust lanes and a large disk of molecular gas. The two galaxies merging in NGC 3256 had similar masses and in a few hundred million years, astronomers say, the two cores will complete the merger to produce a single large elliptical galaxy.
A golden veil cloaks a newborn star
In this NASA/ESA Hubble Space Telescope image, we see a young star breaking out. The golden veil of light cloaks a young stellar object known only as IRAS 14568-6304 in the Circinus molecular cloud complex. This stellar newborn is ejecting gas at supersonic speeds and eventually will have cleared a hole in the cloud, allowing it to be easily visible to the outside universe.
Hubble catches views of a jet rotating with Comet 252P/LINEAR
A sequence of images taken by the NASA/ESA Hubble Space Telescope shows rotation of Comet 252P/LINEAR on 4 April 2016, roughly two weeks after the icy visitor came within 3.3 million miles of Earth, or about 14 times the distance between our planet and the Moon. These observations also represent the closest celestial object Hubble has observed, other than the Moon.
