Constellation of the Altar - Constellations of Ara, Norma and Telescopium - The Altar is a constellation of the southern hemisphere located between the Centaur and the Wolf. Also visible are the constellations of the Rule and the Telescope. Ara (the Altar) is an inconspicuous constellation in the southern sky. It was once considered part of Centaurus and Lupus but became separated when the 'modern' constellation Norma was created by Lacaille in the 1750s. It was recognised by the Greeks and Romans and was visualised as the altar on which the Centaur, Centaurus, was to sacrifice Lupus, the Wolf. This is reflected in its Latin name, Ara Centauri. The constellation is the 63rd largest in the sky and covers about 237 square degrees. The best - known objects in this field are some diffuse dusty nebulae and star clusters. The only named star in Ara is Karnot Mizbeach (ss Ara). Best seen in the early evening in July

Spiral galaxy NGC 7331 in Pegase - Spiral galaxy NGC 7331 in Pegasus: The galaxy NGC 7331 is located about 45 million light years away from Earth. Image obtained with the Hubble Space Telescope. NGC 7331 is located about 45 million light-years away in the constellation of Pegasus (The Winged Horse). Facing us partially edge-on, the galaxy showcases it's beautiful arms which swirl like a whirlpool around its bright central region. Astronomers took this image using Hubble's Wide Field Camera 3 (WFC3), as they were observing an extraordinary exploding star - a supernova - which can still be faintly seen as a tiny red dot near the galaxy's central yellow core. Named SN2014C, it rapidly evolved from a supernova containing very little Hydrogen to one that is Hydrogen-rich - in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. NGC 7331 is similar in size, shape, and mass to the

Cepheides in the galaxy M81 - Cepheids in the galaxy M81 - Cepheides are very bright variable stars that serve as cosmic beacons to measure distance from nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years. Image obtained in 1993. Astronomers have discovered variable stars in the spiral galaxy M81, and measured the distance of the galaxy to be 11 million light - years (3.4 megaparsecs). They quote a 10% uncertainty in this result (plus or minus approximately one million light - years). Previous estimates of the galaxy's distance have ranged from 4.5 to 18 million light - years (1.4 to 5.6 megaparsecs). The astrono

Cepheides in the galaxy M81 - Cepheids in the galaxy M81 - Cepheides are very bright variable stars that serve as cosmic beacons to measure distance from nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years. Image obtained in 1993. Astronomers have discovered variable stars in the spiral galaxy M81, and measured the distance of the galaxy to be 11 million light - years (3.4 megaparsecs).

Shades of red indicate a star much cooler than the Sun, so either at the end of its life, or much less massive.

NGC 634 is located 250 million light years away in the constellation of Andromeda. This spiral galaxy was discovered back in the nineteenth century by English astronomer Edouard Jean - Marie Stephan, but in 2008 it became a prime target for observations thanks to the violent demise of a white dwarf star. The type Ia supernova known as SN2008A was spotted in the galaxy and briefly rivalled the brilliance of its entire host galaxy but, despite the energy of the explosion, it can no longer be seen this Hubble image, which was taken around a year and a half later

Barree spiral galaxy NGC 2146 in the Giraffe - Barred spiral galaxy NGC 2146 in Camelopardalis - NGC 2146 is a barree spiral galaxy located about 70 million years ago - light from Earth in the constellation Giraffe (Camelopardalis). Image obtained by the Hubble Space Telescope (HST). NGC 2146 is classified as a barred spiral due to its shape, but the most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighbouring galaxy is gravitationally perturbing it and distorting the orbits of many of NGC 2146's stars. It is probable that we are currently witnessing the end stages of a process which has been occurring for tens of millions of years. NCG 2146 is undergoing intense bouts of star formation, to such an extent that it is referred to as a starburst galaxy. This is a co

NGC 4710 is a member of the giant Virgo Cluster of galaxies and lies in the northern constellation of Coma Berenices (the Hair of Queen Berenice). It is not one of the brightest members of the cluster, but can easily be seen as a dim elongated smudge on a dark night with a medium - sized amateur telescope. In the 1780s, William Herschel discovered the galaxy and noted it simply as a “” faint nebula””. It is an example of a lenticular or S0 - type galaxy - a type that seems to have some characteristics of both spiral and elliptical galaxies. Image taken by the Hubble Space Telescope

Mars seen by the Hubble Space Telescope - 2016 - Mars in opposition 2016 - Image obtained on 12 May 2016 a few days before the opposition of Mars when the planet was only 80 million km away from Earth. This image shows planet Mars, as it was observed shortly before opposition in 2016, taken when the planet was 50 million miles from Earth on May 12, 2016. by the NASA/ESA Hubble Space Telescope. The photo reveals details as small as 20 miles to 30 miles across. This observation was made just a few days before March opposition on May 22, when the sun and Mars will be on exact opposite sides of Earth. Mars also will be 47.4 million miles from Earth. On May 30, Mars will be the closest it has been to Earth in 11 years, at a distance of 46.8 million miles. Some prominent features of the planet are clearly visible: the ancient and inactive shield volcano Syrtis Major; the bright and oval Hellas Planitia basin; the heavily eroded Arabia Terra in the centre of the image; the dark features of Si

Galaxy M82 view in different wavelength - Galaxy M82 in multi - wavelength - Composite of different images: in blue the image obtained by Chandra in X-rays, in red the infrared image obtained by Spitzer, in yellow, orange, green, the image of Hubble. M82 is an irregular galaxy distant about 12 million years - light from Earth. Its nucleus, which appears to have suffered from the passage of the neighbouring galaxy M81, is in a phase of violent star activity. Its central regions are rich in star formation. These hot stars blow a stellar wind that becomes a very violent galactic wind. Composite of multi - wavelength images of the active galaxy M82 from the three Great Observatories. X - ray data recorded by Chandra appears here in blue; infrared light recorded by Spitzer appears in red; Hubble's observations of hydrogen emission appears in orange, and the bluest visible light appears in yellow - green. Another Hubble observation designed to image 10,000 degree Celsius hydrogen gas (orange

Globular cluster NGC 6752 - Stars in globular cluster NGC 6752 - Image of the center of the globular cluster NGC 6752 located in the constellation Peacock. The Hubble Space Telescope (HST) observed blue straggler. NGC 6752 is a globular cluster, and at over 10 billion years old is one the most ancient collections of stars known. It has been blazing for well over twice as long as our Solar System has existed. NGC 6752 contains a high number of blue straggler”” stars, some of which are visible in this image. These stars display characteristics of stars younger than their neighbours, despite models suggesting that most of the stars within globular clusters should have formed at approximately the same time. Their origin is therefore something of a mystery. Studies of NGC 6752 may shed light on this situation. It appears that a very high number - - up to 38% - - of the stars within its core region are binary systems. Collisions between stars in this turbulent area could produce the blue str
