Ammonite - Artist's view - Early Jurassic ammonite - Artist's view of an ammonite 195 million years ago. A mollusk of the subclass Ammonoidea in a Jurassic sea 195 million years ago. This specimen's planispiral shell is about six inches in diameter. Ammonites were plentiful in the Earth's oceans for about 400 million years becoming extinct, along with the dinosaurs, about 66 million years ago during the Cretaceous - Paleogene (K - Pg) extinction event. While resembling modern shelled nautiloids, these once plentiful mollusks are more closely related to living octopuses, squid, and cuttlefish

Globular cluster M22 in Sagittarius - Globular cluster M22 in Sagittarius - M22 (NGC 6656) is one of the closest globular clusters of the Sun, located about 10 400 years ago - light. Age 12 billion years, it is the third most brilliant globular cluster among the 150 known in the lactee pathway. Image obtained by the Hubble Space Telescope (HST). M22 (NGC 6656) is one of the nearest globular clusters to our sun (distance 10 400 light years). Its stars stretch some 200 light years across and its collective brightness ranks it third among the 150 known Milky Way globulars. It is outshined visually only by the two bright southern globulars, Omega Centauri and 47 Tucanae. M22 is considered an old globular cluster having its beginning some 12 billion years ago not long after the formation of the Milky Way

Galaxy NGC 6240 in Ophiuchus - Galaxy NGC 6240 in Ophiuchus - The galaxy NGC 6240, is about 400 million light years away from Earth in the constellation Ophiuchus. This system consists of two colliding galaxies each with a central black hole; in several millions of years, they will form only one galaxy. Image obtained by the Hubble space telescope on 10 February 2002. NGC 6240 is a peculiar, butterfly - or lobster - shaped galaxy consisting of two smaller merging galaxies. It lies in the constellation of Ophiuchus, the Serpent Holder, some 400 million light - years away. Observations with NASA s Chandra X - ray Observatory have disclosed two giant black holes, about 3,000 light - years apart, which will drift towards one another and eventually merge together into a larger black hole. The merging process, which began about 30 million years ago, triggered dramatic star formation and sparked numerous supernova explosions. The merger will be complete in some tens to hundreds of millions of

Kepler is the rest of a supernova that exploded about 400 years ago located about 13,000 light years from Earth in the constellation Ophiuchus.

Middle Jurassic ammonites - Ammonites - Artist's view - View of ammonites artist 170 million years ago. Mollusks of the subclass Ammonoidea in a Jurassic sea 170 million years ago. The planispiral shells are about 30 inches in diameter, making them among the larger known ammonites. Also in this image are ray - finned fish of the infraclassTeleostei and jellyfish of the order Scyphozoa. Ammonites were plentiful in the Earth's oceans for about 400 million years becoming extinct, along with the dinosaurs, about 66 million years ago during the Cretaceous - Paleogene (K - Pg) extinction event. While resembling modern shelled nautiloids, these once plentiful mollusks are more closely related to living octopuses, squid, and cuttlefish

Supernova 1987A appeared in the constellation Doradus on February 23, 1987. Sometime during 23 February 1987 a supernova exploded in the Large Magellanic Cloud (LMC), a nearby galaxy. However, the LMC is about 170,000 light years distant, so the supernova exploded 170,000 years ago. It was discovered the following day and brightened rapidly to become the first supernova to be easily visible to the unaided eye for almost 400 years. This photograph shows the field around the site of the supernova in great detail about 10 days afterwards, when it was still brightening

7 Wonders of the World: The Lighthouse of Alexandria - Egypt - The Pharos of Alexandria at twilight - The Pharos (lighthouse) of the ancient Egyptian city of Alexandria as it may have appeared 2,000 years ago. The lighthouse, one of the Seven Wonders of the Ancient World, was commissioned in the 3rd century BC by Ptolemy I and completed 12 years later under the rule of his son Ptolemy II. Built mostly with solid blocks of limestone, it is believed to have been about 400 feet tall (about 40 stories) making it one of the tallest man - made structures for many hundreds of years. It sat on the small island of Pharos near the coast of the Nile Delta's western edge, guiding ships to Alexandria's Great Harbor for nearly 1,500 years. The Pharos of Alexandria survived several major earthquakes until finally falling into ruin in in the 14th century. About 100 years later its limestone was used to construct the Citadel of Qaitbay at the same location

They were simple plants, standing only a few inches tall, consisting of slender stalks with branches and rounded structures called sporangia. The sporangia, common to funguses and non - seed plants, produced and contained the spores required for reproduction

In the center, a small group of very massive and extremely hot stars, stars of Wolf - Rayet. Image obtained by Siding Spring's 3.9m telescope. At the centre of this remarkable bubble - like nebula nebula is a small group of extremely hot stars. Some of these stars are rapdly losing mass and have stellar winds blowing from their surfaces with velocities that approach 4000 kilometers per second. Such stars are known as Wolf - Rayet stars and are found in galaxies capable of forming massive stars. There are many such stars in the Large Magellanic Cloud (LMC) but not all of them are associated with distinctive nebulae.

Exoplanete OGLE-2013-BLG-0341L Bb - Artist's view: OGLE-2013-BLG-0341L Bb is an exoplanet about twice the mass of the Earth gravitating around the red dwarf OGLE-2013-BLG-0341L B, a secondary component of the binary star OGLE-2013-BLG-0341L located in the constellation. OGLE-2013-BLG-0341LBB, is located in the constellation Sagittarius, about 3,000 light-years away. It is twice the mass of Earth, and orbits one of the stars in the binary system at almost exactly the same distance from which Earth orbits the Sun. But its star is 400 times dimmer than our Sun, so the exoplanet is very cold - around minus 213 degrees Celsius

Supernova 1987A in the Great Magellan Cloud before and after explosion - Sometime during 23 February 1987 a supernova exploded in the Large Magellanic Cloud (LMC), a nearby galaxy. However, the LMC is about 170,000 light years distant, so the supernova exploded 170,000 years ago. It was discovered the following day and brightened rapidly to become the first supernova to be easily visible to the unaided eye for almost 400 years. This photograph shows the field around the site of the supernova in great detail, both before the supernova exploded (right) and about 10 days afterwards, when it was still brightening. The image of the star that exploded to create the supernova (mouseover the image) is elongated (better seen on this bigger image). This does not necessarily indicate any peculiarity or a close companion, rather it is the effect of stars being by chance aligned along the line of sight. Several other examples can be seen in this picture and other, different, blended images are seen

Diameter of Earth: 12 756.28 km Diametre of Jupiter: 142,984 km Jupiter's diameter is over ten times greater than the Earth's. If you weigh 180 pounds on Earth, you would weigh 426 pounds at Jupiter's cloud tops. Jupiter is five times further from the Sun than the Earth. Jupiter is so large that its famous Great Red Spot (actually a giant, hurricane-like storm that's at least 400 years old) would easily swallow the Earth. Jupiter spins so fast on its axis that it bulges noticeably at its equator (a day on Jupiter is about ten hours long)

Discovered in 1995 in the Pleiades cluster, about 55 times the mass of Jupiter, this brown dwarf is represented here in the sky of a young exoplanet lit by the star. 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. Teide 1 is probably only about 120 million years old (compared to our sun's age of 4.5 billion years) and shines at a temperature of 4,000o F,

Remains of the Crab Supernova (M1) in the Taurus - M1, the Crab Nebula, is a supernova remnant from a star that exploded in July or August of 1054 AD and was witnessed and described by Chinese astronomers as being six times brighter than Venus. The supernova, located in the constellation of Taurus and about 7,000 light years away from the Earth, shined with the light of 400 million suns, was visible in the daytime for almost a month, and remained visible in the evening sky for more than a year. Today, some 900 years later, we see the remains of the exploded star as a cloud of gaseous debris, illuminated by the remnants of the core of the original star, which is now a rapidly spinning neutron star called a pulsar. The colors in the nebula come from two different sources. The red filaments come from typical hydrogen emission such as in emission nebula like M8. The diffuse blue background has a continuous spectrum composed of synchrotron radiation which is emitted by high energy electrons

Visible in the constellation Taurus, this cluster is 440 years from the Earth. The Pleiades are one of the finest and nearest examples of a reflection nebula associated with a cluster of young stars. The cluster itself is a group of many hundreds of stars about 400 light years from Earth in the northern constellation of Taurus and has been recognised since ancient times. Seven of the brightest stars are quite easy to see with the unaided eye and bear the names of the Seven Sisters, the daughters of Atlas. The nebulosity seen here is light reflected from the particles in a cloud of cold gas and dust into which the cluster has drifted. It appears blue because these tiny interstellar particles scatter blue light more efficiently than the longer wavelengths of red light and it is streaky because of the distribution of dust particles in space

Planetary nebula Helix (NGC 7293) in Aquarius - Planetary nebula Helix (NGC 7293) - This nebula is located 690 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope This faint object is the nearest planetary nebula to the Sun and on deep photographs has a diameter of about half a degree - - the same apparent size as the Sun in the sky. The AAT colour picture shows the brighter parts of the nebula, revealing various ionization levels within the shell of matter ejected from the central star. The greenish middle portion is evidence of excited oxygen atoms, while the outer red is predominantly light from nitrogen and hydrogen. The smallest of the radial blobs inside the red shell are about 150 astronomical units across (150 times the Earth - Sun distance) and they give this beautiful object its alternative name, the Sunflower Nebula. The Helix is about 400 light years away, or about 100 times more distant than the nearest stars

Open cluster of Pleiades seen in infrared - The Pleiades open cluster seen in infrared - Clouds of dust in the Pleiades cluster seen in infrared by the Spitzer space telescope. The Pleiades star cluster contains about 500 stars formed 100 million years ago. It is located 440 light years from Earth, in the constellation Taurus. The Pleiades, located more than 400 light - years away in the Taurus constellation, is a star cluster born when dinosaurs still roamed the Earth, about 100 million years ago. It is significantly younger than our 5 - billion - year - old sun. The brightest members of the cluster, also the highest - mass stars, are known in Greek mythology as two parents, Atlas and Pleione, and their seven daughters, Alcyone, Electra, Maia, Merope, Taygeta, Celaeno and Asterope. There are thousands of additional lower - mass members, including many stars like our sun. Some scientists believe that our sun grew up in a crowded region like the Pleiades, before migrating to its present

Galaxy System Arp 274 - Galaxy triplet Arp 274 - Arp 274 (NGC 5679) is a system of three galaxies located about 400 million years ago - light in the constellation of Virgo. Image obtained by the Hubble Space Telescope. Arp 274, also known as NGC 5679, is a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation. Two of the three galaxies are forming new stars at a high rate. This is evident in the bright blue knots of star formation that are strung along the arms of the galaxy on the right and along the small galaxy on the left. The largest component is located in the middle of the three. It appears as a spiral galaxy, which may be barred. The entire system resides at about 400 million light - years away from Earth in the constellation Virgo. Hubble's Wide Fi

The combined image unveils a bubble - shaped shroud of gas and dust that is 14 light - years wide and is expanding at 4 million miles per hour (2,000 kilometers per second). Observations from each telescope highlight distinct features of the supernova remnant, a fast - moving shell of iron - rich material from the exploded star, surrounded by an expanding shock wave that is sweeping up interstellar gas and dust. Each color in this image represents a different region of the electromagnetic spectrum, from X - rays to infrared light. The X - ray and infrared data cannot be seen with the human eye.

Neptune - Illustration - Neptune's Great Dark Spot - Illustration - Artist's view of Neptune with its ring system and large dark spot observed by the Voyager 2 probe in 1989. This is how Neptune's Great Dark Spot and rings may have looked in 1989 from a position just beneath Neptune's ring plane. The outermost Adams ring is near the top of the frame, and beneath that is the much broader and diffuse Lassell ring. Further in toward Neptune and abutting the Lassell ring is the thin Le Verrier ring, and beyond that is the diffuse Galle ring. The Great Dark Spot is believed to be a storm similar to, but only half the size of, Jupiter's Great Red Spot. While Jupiter's Great Red Spot has been raging for at least 400 years, subsequent observations of Neptune's Great Dark Spot in 1994 by the Hubble Space Telescope revealed that this storm has since disappeared. The Great Dark Spot was a very dynamic weather system, generating massive, white clouds similar to high - altitude cirrus clouds on Ear

Herschel provides a detailed look at the cool clouds of star birth that line the galaxy's five concentric rings. Massive young stars are heating blankets of dust that surround them, causing them to glow in the longer - wavelength infrared light, known as far - infrared, that Herschel sees.
