Zodiacal lights in the morning and evening - Zodiacal lights - morning and evening - The visible glow in the sky is called the zodiacal light. It comes from the reflection of the light of the Sun on the countless interplanetary dust; it draws the plane of the Solar System. At the top, on the morning of 1 November 2006, the light is tilted to the right (south); below, on 9 March 2007 at sunset, this light is tilted to the left (south). The faint cone of light extending from the horizon along the ecliptic is known as zodiacal light. It comes from the reflexion of the sun's light off tiny interplanetary dust particles in the plane of the solar system. Top, November 1st 2006 in the morning, zodiacal light is leaning right (south); bottom, March 9 2007, sunset, zodiacal light towards left (south)

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. The X-ray image obtained by the Chandra space telescope highlights areas where the gas reaches the highest temperatures (in dark blue) - Kepler's supernova remnant, first seen 400 years ago by sky watchers, including famous astronomer Johannes Kepler. The Chandra X-ray data show regions of very hot gas, and extremely high-energy particles. Kepler's supernova, the last such object seen to explode in our Milky Way galaxy, resides about 13,000 light-years away in the constellation Ophiuchus. The Chandra observations were taken in June 2000: Remains of the supernova Kepler in Ophiuchus - Kepler's supernova remnant

Solar Orbiter - Solar Orbiter is a solar observation satellite of the European Space Agency (ESA) developed with the participation of NASA, which is scheduled to launch in February 2019 and begin observations around 2022. The main objective of this scientific mission is to study the processes behind the solar wind, the heliospheric magnetic field, the energetic solar particles and the magnetic field of the Sun. Esa's Solar Orbiter is set to provide new views of our star, in particular providing close-up observations of the Sun's poles. Following its launch in February 2019 and three-year journey using gravity swingbys at Earth and Venus, Solar Orbiter will operate from an elliptical orbit around the Sun. At its closest it will approach our star within 42 million kilometers, closer than planet Mercury. An artist's impression of Solar Orbiter in front of the stormy Sun is depicted here

Pulsar of Crab in Taurus seen in X - The Crab nebula pulsar - Pulsar of Crab in Taurus seen in X by satellite Chandra. The pulsar is the white dot in the center of the image. This neutron star generates a powerful magnetic field creating material jets at the poles, as well as a strong stellar wind. This image gives the first clear view of the faint boundary of the Crab Nebula's X - ray - emitting pulsar wind nebula. The nebula is powered by a rapidly rotating, highly magnetized neutron star, or pulsar (white dot near the center). The combination of rapid rotating and strong magnetic field generates an intense electromagnetic field that creates jets of matter and anti - matter moving away from the north and south poles of the pulsar, and an intense wind flowing out in the equatorial direction. The inner X - ray ring is thought to be a shock wave that marks the boundary between the surrounding nebula and the flow of matter and antimatter particles from the pulsar. Energetic electrons and

Nebula NGC 6559 in Sagittarius - NGC 6559 and IC 1274 - 75 in Sagittarius - Located in Sagittarius, this nebula is located at a distance of about 5000 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. This dusty region is probably associated with the brighter and better - known Lagoon and Trifid Nebulae which are nearby in the sky and part of the same molecular cloud. The soft red glow of fluorescent hydrogen is evidence that there are young hot stars associated with the dusty clouds. These bright stars also illuminate the tiny solid particles, producing blue reflection nebulae bordering some of the emission regions. The dust is also evident in silhouette, both as sinuous dark lanes winding through the luminous gas and as the dark patches obscuring the ancient, yellow stars that populate the central parts of the Milky Way

It is home to a cluster of young stars NGC 6193, formed three million years ago. Image obtained by Siding Spring's 3.9m telescope. Here we see two bright stars whose radiant energy is beating down on to the surface of a dark cloud, very similar to the Horsehead in Orion. The cloud itself is opaque and because of that, very cold inside. These conditions are ideal for the formation of organic molecules on the surfaces of the chilled dust particles. The opacity of the cloud protects the fragile molecules within from the energetic radiation of nearby stars, but as its surface is gradually warmed and eroded, the delicate organic molecules are destroyed and the hydrogen released glows as a distinctive red emission nebula

Launched on August 28, 2002, it is a geostationary satellite located 35 600 km from Earth; dedicated to meteorology, it observes the Earth in visible, and in infrared. Meteosat Second Generation (MSG), is equipped with an extremely sophisticated imaging radiometer that can separate the incoming radiation into 12 (3 with the current Meteosat) different spectral bands. Each section, four of them in the visible and eight in the thermal infrared, delivers different information. They vary from visible images of weather systems during the day to cloud temperature at night; from surface temperature and water vapour to trace gas concentrations and dust particles in the atmosphere. MSG will deliver about twenty times as much information as its predecessor Meteosat, resulting in much more accurate short and medium - range forecasts

Remains of the Supernova of Vails - Detail - The Vela supernova remnant - Nearly 12,000 years ago, a massive star exploded in the constellation Vails. This image shows part of the rest of this supernova where the hydrogen atoms appear in red and the oxygen in blue - green. Approximately 11,000 to 12,000 years ago a massive star exploded in the southern constellation of Vela. The matter ejected by the supernova scattered the contents of the star into the surrounding interstellar medium creating shock fronts of multimillion degree gas and high energy particles. The heated matter produces brilliant visible light as well as radio and x - ray emission which will continue for thousands of years until the entire remnant of the dying star completely dissipates into space. This image captures some of that filamentary and gigantic shock in visible light. Hydrogen atoms being excited by atomic collisions glow red, while oxygen appears blue - green

That NGC 3603 is the more distant is confirmed by its colour, which is a ruddier red than the pinkish hue of NGC 3576.

Star Antares in the Scorpion - The nebula around Antares - Supergeant star Antares seen at the 3.9m telescope of Siding Spring. To his right is the globular cluster NGC 6144. Antares is a giant among stars, and like giants in general, very rare. Antares has spent most of its short life as a highly luminous blue supergiant star, its mass obliging it to consume its vast store of nuclear fuel (hydrogen) very rapidly. This nuclear fusion process supplied the energy that prevented the star collapsing in on itself - - all stars support themselves against gravity in this way.

Star Antares in the Scorpion - The nebula around Antares - Supergeant star Antares seen at the 3.9m telescope of Siding Spring. To his right is the globular cluster NGC 6144. Antares is a giant among stars, and like giants in general, very rare. Antares has spent most of its short life as a highly luminous blue supergiant star, its mass obliging it to consume its vast store of nuclear fuel (hydrogen) very rapidly. This nuclear fusion process supplied the energy that prevented the star collapsing in on itself - - all stars support themselves against gravity in this way.

Launched on August 28, 2002, it is a geostationary satellite located 35 600 km from Earth; dedicated to meteorology, it observes the Earth in visible, and in infrared. Meteosat Second Generation (MSG), is equipped with an extremely sophisticated imaging radiometer that can separate the incoming radiation into 12 (3 with the current Meteosat) different spectral bands. Each section, four of them in the visible and eight in the thermal infrared, delivers different information. They vary from visible images of weather systems during the day to cloud temperature at night; from surface temperature and water vapour to trace gas concentrations and dust particles in the atmosphere.

Nebula IC 2220 in the Carene - A mass - loss star in IC 2220 - This nebula is illuminated by a giant red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. The bright, supergiant star at the centre of this nebula is known only by its catalog designation, HD 65750. The nebulosity around the star is the result of light reflected by dust surrounding it. The dust is thought to consist mainly of particles of silica condensed from material which the star is losing from its distended surface at a fairly steady rate. The rate of mass loss is much higher than in normal stars and is sufficient to produce the reflection nebula IC 2220. The stellar nature of the central object is revealed by the four diffraction spikes extending from it. These are artifacts due to structures within the telescope. The light from the star has also produced the annular halation ring (a photographic artefact) that ornaments the nebula. These features, real or otherwise, have provoked the name '

S star Monocerotis and nebula - Fox Fur nebula in Monoceros - The region to the right of the bright star S Monocerotis is called Fox Fur nebula. This region where gas mixes with interstellar dust is located above the Cone nebula, about 2600 light years from Earth. Image obtained with a 50 cm telescope, composite of several images. The region around the 4.7 magnitude star S Mon is a fascinating mixture of red fluorescent hydrogen and dark, obscuring dust lanes. Some dust patches are close enough to bright stars to reflect light from them; these appear blue for the same reason that the day - time sky is blue - because some of the interstellar particles preferentially scatter blue light. The dust is mixed with gas and this affects the appearance of the emission nebulae, giving some of the faintest a curious 'fox fur' texture in this photograph. S Mon is part of a young open cluster of stars named NGC 2264 located about 2600 light years away, just north of the Cone nebula

NGC 3372 is located about 7000 light years away from Earth. Image obtained in July 2009. Composed of gas and dust, the pictured pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7500 light - years away in the southern constellation of Carina. Taken in visible light, the image shows the tip of the three - light - year - long pillar, bathed in the glow of light from hot, massive stars off the top of the image. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure. Hubble's Wi

Solar eruption seen by SOHO 02/04/2001 - Large solar flare seen by SOHO on april 2 2001 - Solar eruption seen by SOHO satellite; the Sun is masked by a coronographer. An image of the Sun taken at the same time by another satellite instrument was superimposed. A large solar flare occurred at 4:51 p.m. EDT, on Monday, April 2, 2001. as Observed by the Solar and Heliospheric Observatory (SOHO) satellite. Solar flares, among the solar systems mightiest eruptions, are tremendous explosions in the atmosphere of the Sun capable of releasing as much energy as a billion megatons of TNT. Caused by the sudden release of magnetic energy, in just a few seconds, solar flares can accelerate solar particles to very high velocities, almost to the speed of light, and heat solar material to tens of millions of degrees. The recent explosion from the active region near the sun's northwest limb hurled a coronal mass ejection into space at a whopping speed of roughly 7.2 million kilometers per hour. Luckily,
