Colliding spiral galaxies NGC 2207 and IC 2163 - Colliding galaxies NGC 2207 and IC 2163 - The galaxies NGC 2207 (left) and IC 2163 (right) form a pair of colliding galaxies approximately 114 million light years away. Currently IC 2163 is moving away from NGC 2207, but it is likely that within several billion years these two galaxies will eventually merge into a single massive galaxy. Image obtained by the Hubble Space Telescope in 1998. The larger and more massive galaxy is cataloged as NGC 2207 (on the left in the Hubble Heritage image), and the smaller one on the right is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light - years towards the right - hand edge of the image. The calculations indicate that IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient ener

Spiral galaxy NGC 7424 in the Crane - Galaxy NGC 7424 in Grus - The barree spiral galaxy NGC 7424 is located about 40 million years away from Earth. NGC 7424 extends over nearly 100,000 light years, like our galaxy. Numerous bright blue clusters of massive young stars are visible along the spiral arms. Image obtained by the telescope MELIPAL of the VLT on October 9, 2004 Composite colour - coded image of spiral galaxy, NGC 7424, at a distance of 40 million light - years. This galaxy is classified as “” SAB (rs) cd””, meaning that it is intermediate between normal spirals (SA) and strongly barred galaxies (SB) and that it has rather open arms with a small central region. It also shows many ionised regions as well as clusters of young and massive stars. Ten young massive star clusters can be identified whose size span the range from 1 to 200 light - years.

Artist view of Beta Pictoris b - Beta Pictoris b. Artwork: Artist's view of Beta Pictoris b, a giant exoplanet with a mass equivalent to 9 times the mass of Jupiter orbit around the star Beta Pictoris. This artist's impression shows how the planet inside the disc of Beta Pictoris may look. Only 12 million years old, or less than three-thousandths of the age of the Sun, Beta Pictoris is 75% more massive than our parent star. It is located about 60 light-years away towards the constellation of Pictor (the Painter) and is one of the best-known examples of a star surrounded by a dusty debris disc. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell-tale signs that strongly suggested the presence of a massive planet. Observations done with the NACO instrument on Eso's Very Large Telescope in 2003, 2008 and 2009, have proven the presence of a planet around Beta Pictoris. It is located at a distance between 8 and 1

Cocoon Nebula (IC 5146) in Swan - Cocoon Nebula - IC 5146 - in Cygnus - The Cocon Nebula, IC 5146, is an emission nebula located about 4000 years from Earth in the constellation of Swan. This complex mass of molecular hydrogen and dust, located 4,000 light years from earth, glows red by emitting light, shines blue by reflecting light and exhibits a pattern of dark lanes that result when dust absorbs light. Much of the light seen in the main part of this nebula is generated by the massive bright star near it's center. The Cocoon is a stellar nursery containing a relatively young open cluster of stars with several individual constituents that are newly formed. Wide angle, long exposure photographs reveals the nebula to be very extensive - essentially a vast river of interstellar dust

Exoplanete in formation - NGC 2547-ID8: Illustration of the collision between two asteroids in the habitable zone of the star NGC 2547-ID8. This could result in an accretion-forming rocky exoplanet. Planets, including those like our own Earth, form from epic collisions between asteroids and even bigger bodies, called proto-planets. Sometimes the colliding bodies are ground to dust, and sometimes they stick together to ultimately form larger, mature planets. This artist's conception shows one such smash-up. Spitzer's infrared vision detected a huge eruption around the star NGC 2547-ID8 between August 2012 and 2013. Scientists think the dust was kicked up by a massive collision between two large asteroids. They say the smashup took place in the star's “” terrestrial zone,””” the region around stars where rocky planets like Earth take shape.

This is how Teide 1 might appear from the surface of a hypothetical, March - like planet. Discovered in 1995, Teide 1 is a type of mysterious object called a brown dwarf (failed star or super planet). Bigger than a planet, but smaller than a star, this brown dwarf is about 400 light years from the Earth in the Pleiades star cluster. It is thought that Teide 1 has the mass equivalent of about 55 Jupiters, which is considered large for a brown dwarf. Teide 1 is massive enough, and hence hot enough, to sustain lithium fusion in its core, but is unable to initiate hydrogen fusion like our sun.

Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars. As the rapidly moving blast wave encounters the relatively stationary interstellar medium it creates a very narrow, luminous shock front that appears as a faint nebula. Because the shock front is very convoluted the nebulosity appears to be highly structured and the various colours define different energy levels within the interaction. Although the star responsible for the Vela supernova remnant exploded 12,000 years ago, it is still affecting its env

Alpha Centauri is at lower left and with its companion, beta points (more or less) to the Southern Cross, which in turn lies alongside the Coalsack, one of the nearest dust clouds. Further along the Milky Way is the astonishing Carina nebula, which is home to eta Carinae, probably the most massive star known, and a prime candidate for the next Galactic supernova.

The elongated red 'star' marks the site of supernova 1987A in the Large Magellanic Cloud (LMC). The two blue stars that bracket the glowing ember are almost certainly in the LMC as well, but not necessarily near the supernova. They initially confused the issue of which star had exploded. The red image is the expanding remnant of a massive star and can be seen to be slightly elongated in this picture. The elongation is in the same direction as the well - known Hubble Space Telescope picture of the ellipse around the supernova and both represent the expanding shock wave from the supernova interacting with material that was ejected from the star before it exploded

Artist's view of a neutron star - Neutron star - Artwork: A neutron star is a very dense star resulting from the explosion of a massive supernova star. It is called pulsar if it turns quickly on itself and develops a powerful magnetic field emitting beams of light and radio waves. A neutron star is formed from the collapsed remnant of a massive star. When it turns very fast with a powerful magnetic field with emission beams, it is a pulsar

Spiral galaxy of the Sombrero M104 infrared view - Sombrero galaxy seen in infrared - Infrared image of the spiral galaxy M104 (Sombrero galaxy), located about 28 million years ago - light, obtained with the Spitzer space telescope in 2004 and January 2005. Infrared radiation shows the dust of the disc visible throughout the circumference. A high emission also comes from the center of the galaxy where a supermassive black hole is thought to reside there. This spiral galaxy is located some 28 million light - years away. The infrared image obtained by Spitzer space telescope in 2004 and 2005 pierces through the obscuring dust, along with the bulge of stars. It shows that the disk is warped, which is often the result of a gravitational encounter with another galaxy; clumpy areas spotted in the far edges of the ring indicate young star - forming regions. Spitzer detected infrared emission not only from the ring, but from the center of the galaxy too, where there is a huge black hole, belie

Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. The line that crosses the image is the trace left by the passage of a satellite during the photo shoot. Image obtained with Siding Spring's 3.9m telescope. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars. As the rapidly moving blast wave encounters the relatively stationary interstellar medium it creates a very narrow, luminous shock front that appears as a faint nebula. Because the shock front is very convoluted the nebulosity appears to be highly structured and the various colours define different

Galaxy clusters Abell 370 - Abell 370 cluster of galaxies with gravitational arcs - This cluster contains a large number of galaxies, most of which are elliptical. A gravitational arc is visible at the bottom of the image. This is the deformed image of a galaxy farther away behind the cluster. This cluster hosts one of the most prominent gravitational arcs known to date. The light of a very remote object is deformed by the foreground cluster. Abell 370, at the center of the photo, contains a large number of galaxies - most of them are ellipticals. The two brightest red galaxies slightly above the gravitational arc are the most massive in the cluster and give an important contribution to the lensing event. This gravitational arc - in combination with the cluster of galaxies - provides a natural laboratory to study the physics of gravity. The exact shape of the arc allows to estimate the mass of the cluster through the equations of general relativity

Brown dwarf & debris ring from an oblique perspective - Artist's view of a brown dwarf star about 60 times the mass of Jupiter, surrounded by a disc of dust and rocks. In the foreground, a primitive exoplanet enlighted by the star. A small, barren planet orbits obliquely to the plane of a massive set of concentric dust rings surrounding a brown dwarf of about 60 Jupiter masses. These rings are evocative of Saturn's famous rings of rock and ice, however there is likely no ice in the rings around this dwarf. Recent observations have revealed that some brown dwarfs may be surrounded by rings of dust. While the origin of these rings, and the brown dwarfs themselves, is unclear, it's thought that material from these rings may even coalesce into planets, providing some brown dwarfs with their own solar systems

Crab Pulsar in Nebula M1 - The Crab pulsar: This false-colored image obtained by the Hubble Space Telescope shows the central region of the Crab Nebula or resides its pulsar. The pulsar is visible in the center of the image. It is a very dense neutron star from the explosion of a massive supernova star. This star quickly rotates on itself developing a powerful magnetic field, emitting beams of light and radio waves. M1 is located about 6000 light-years in the constellation Taurus.. In 1054 AD, during the Song dynasty, Chinese astronomers spotted a bright new star in the night sky. This newcomer turned out to be a violent explosion within the Milky Way, caused by the spectacular death of a star some 1600 light-years away. This explosion created one of the most well-studied and beautiful objects in the night sky - the Crab Nebula.
