Double star Gliese 623 - Double star system Gliese 623 in Hercules - Gliese 623 is a double star located about 25 years ago - light in the constellation Hercules. The Hubble space telescope was able for the first time to obtain an image of the two stars that make up this system, in June 1994. The two stars are separated by about twice the distance from Earth to Sun. On the right, 623b, a star 60,000 times less bright than the Sun, and 10 times less massive. Its nature is misidentified, it's a red dwarf or a brown dwarf. A dim double star system cataloged as Gliese 623 lies 25 light - years from Earth, in the constellation of Hercules. The individual stars of this binary system were distinguished for the first time when the Hubble Space Telescope's Faint Object Camera recorded this image in June 1994. They are separated by 200 million miles - about twice the Earth/Sun distance. On the right, the fainter Gliese 623b is 60,000 times less luminous than the Sun and approximately 10 times le

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

Spiral galaxy NGC 2683 in Lynx - Spiral galaxy NGC 2683 in Lynx - Spiral galaxy NGC 2683 distant about 16 million years - light in the constellation Lynx. Image obtained by the Hubble Space Telescope (HST). NGC 2683 is a spiral galaxy seen almost edge - on, giving it the shape of a classic science fiction spaceship. The delicate dusty lanes of the spiral arms are silhouetted against the golden haze of the galaxy's core. In addition, brilliant clusters of young blue stars shine scattered throughout the disc, mapping the galaxy's star - forming regions. Perhaps surprisingly, side - on views of galaxies like this one do not prevent astronomers from deducing their structures. Studies of the properties of the light coming from NGC 2683 suggest that this is a barred spiral galaxy, even though the angle we see it at does not let us see this directly.

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

Barree spiral galaxy NGC 1559 and supernova - Barred spiral galaxy NGC 1559 with a supernova - The galaxy NGC 1559 is a galaxy of Seyfert located about 50 million years ago - light in the constellation Reticule. In this image obtained in 2005 by the Kueyen European telescope of the VLT in Chile, a bright star is visible just above the galaxy, a supernova of type Ia named SN 2005df. On the night of August 4, 2005, an amateur astronomer and supernovae discoverer Reverend Robert Evans discovered a supernova just North of this galaxy. This supernova is classified as a somewhat unusual type Ia supernova, caught probably 10 days before it reached its maximum brightness. Such a supernova is thought to be the result of the explosion of a small and dense star - a white dwarf - inside a binary system. As its companion was continuously spilling matter onto the white dwarf, the white dwarf reached a critical mass, leading to a fatal instability. NGC 1559 is a SBc (s) - type spiral galaxy located a

Galaxy NGC 4650A in Centaurus - Galaxy NGC 4650A in Centaurus - The polar ring galaxy NGC 4650A is located about 130 million years away from Earth. The host galaxy is surrounded by a polar ring shaped like gas and stars. This type of galaxy is rarely observed. This image was obtained by the ANTU telescope of the VLT in 1998. This is a colour photo from the VLT that shows NGC 4650A, a member of the so - called Centaurus chain of galaxies in the southern constellation of that name. NGC 4650A is a complex system that is located at a distance of about 130 million light - years. There are two main components, a lenticular - shaped galaxy (of type S0), surrounded by a knotty extended ring - like distribution of stars, dust and gas, almost perpendicular to each other. The stars in the central, structureless region and the material (stars, gas, and dust) in the outer disk rotate in two different planes that are almost perpendicular to each other.

Central region of the elliptical galaxy Centaurus A (NGC 5128) - Central part of the galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million years away from Earth in the southern constellation of Centaurus. A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This giant galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. The nearby radio source Centaurus A (NGC 5128) looks like an elliptical galaxy, crossed by a broad, irregular dust lane. The dark band is probably the remains of a dusty spiral galaxy which is being absorbed by the giant elliptical. One

Markarian Galaxy 817 - Galaxy Markarian 817 - The spiral galaxy Markarian 817 is located 430 million light years ago in the constellation Dragon. This galaxy houses in its heart a supermassive black hole. Image obtained by the Hubble Space Telescope on August 2, 2009. Rings of brilliant blue stars encircle the bright, active core of this spiral galaxy, whose monster black hole is blasting material into space at over 14 million kilometers per hour. Viewed nearly face - on, the galaxy, called Markarian 817, shows intense star - forming regions and dark bands of interstellar dust along its spiral arms. Observations by the new Cosmic Origins Spectrograph (COS) aboard the NASA/ESA Hubble Space Telescope captured the powerful outflow of material from this galaxy. The COS spectrum of Markarian 817 highlights the outflow's dynamic nature. A gas cloud containing hydrogen that was detected in Hubble data taken in 1997 does not appear in the COS observation because the cloud has apparently been d

It contains about 500 stars, 150 of which are brilliant. It is about 300 million years old. The planetary nebula NGC 2438 does not appear to belong to this cluster, and must be closer although its distance is unknown. M46 is a rich open cluster that contains a real jewel, planetary nebula NGC 2438. At 6th magnitude, M46 contains about 100 bright stars, the brightest of which is magnitude 8.7. It is about one - half degree in apparent diameter, the same size as the full moon. It is estimated to be about 300 million years old. Planetary nebula NGC 2438 is about one arc minute in diameter and shines at 10th magnitude. A planetary nebula is a shell of gas puffed off by a star late in its life cycle. Three bright stars are visible inside of the nebula, although none of them are the true central star which shed the gas. T

This star is a red dwarf, 10,000 times less luminous than our Sun, and is invisible to the naked eye. Its proximity makes it move quickly ahead of the other stars. This composite image made from three images taken in 1976 (blue), 1982 (red) and 1993 (green) shows the shift of the star in 17 years. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. Proxima Centauri is the nearest known star to the sun, at a distance of about 4.2 light years. It is an intrinsically faint red star, more than ten magnitudes (ten thousand times) fainter than the Sun. It is also much cooler, with a surface temperature of about 3100 C. Its visual (apparent) magnitude is eleven, so it is only visible with a good telescope, and only then from southern latitudes. Proxima is about one - tenth t

This interacting galaxy houses a quasar in its center. It is one of the brightest ultra-bright infrared galaxy known to date. It has a central black hole and intense star formations are observed. Image obtained by the Hubble Space Telescope on May 10, 2002. The extraordinary galaxy UGC 8058, also known as Markarian 231, was discovered in 1969 as part of a survey searching for galaxies with strong ultraviolet radiation. It has long tidal tails and a disturbed shape. Results from the first spectrum showed clear signs of the presence of a powerful quasar in the center that made Markarian 231 unique in the Markarian sample. Markarian 231 has maintained its reputation as an exceptional object since those early observations and continues to be a favorite target in all wavelength regimes. Its infrared lumino

And yet, this supernova, called SN 2004dj (middle left), resides far beyond our galaxy. Its home is in the outskirts of NGC 2403, a galaxy located 11 million light - years from Earth. Although the supernova is far from Earth, it is the closest stellar explos

Asteroid belts around the star Epsilon Eridani - Asteroid belts around Epsilon Eridani - Artist's view of the planetary system around the star Epsilon Eridani. This star is located 10 years from Earth. Observations made by the Spitzer space telescope in 2008 show that this system has two asteroid belts. An exoplanet had already been discovered around this star in 2000. This artist's conception shows the closest known planetary system to our own, called Epsilon Eridani. Observations from Nasa's Spitzer Space Telescope show that the system hosts two asteroid belts, in addition to previously identified candidate planets and an outer comet ring. Epsilon Eridani is located about 10 light - years away in the constellation Eridani. It is visible in the night skies with the naked eye. The system's inner asteroid belt appears as the yellowish ring around the star, while the outer asteroid belt is in the foreground. The outermost comet ring is too far out to be seen in this view, but comets orig

Open cluster Westerlund 2 in Carene - Open cluster Westerlund 2 in Carina - The open cluster Westerlund 2 is located about 20,000 years - light in the southern constellation of Carene, within the nebula Gum 29. About 3000 stars form this cluster. It contains a significant number of massive stars including one of the most massive stars known to date: WR 20a. Image obtained by the Hubble Space Telescope. The sparkling centerpiece of this image taken by the Hubble space telescope is a giant cluster of about 3,000 stars called Westerlund 2, named for Swedish astronomer Bengt Westerlund, who discovered the grouping in the 1960s. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light - years away from Earth in the constellation Carina. To capture this image, Hubble's near - infrared Wide Field Camera 3 near - infrared pierced through the dusty veil shrouding the stellar nursery, giving astronomers a clear view of the nebula and the dense concentration
