Two of the four largest shield volcanoes on Mars are within the northwestern part, the south half of Pavonis Mons and Arsia Mons. The eastern part includes Syria and Sinai Plana. Most of the quadrangle forms the Tharsis plateau--the highest plateau on Mars; its elevation, 10 km, is twice that of the Tibetan Plateau, the highest plateau on Earth. Also in the northeastern part is Noctis Labyrinthus, a complex system of fault valleys at the west end of Valles Marineris. The south-central part is marked by the large fault system, Claritas Fossae. Latitude range -30 to 0 degrees, longitude range 90 to 135 degrees.</div><br />Image Credit: NASA/JPL/USGS<br />Explanation from: http://photojournal.jpl.nasa.gov/catalog/pia00177

Kepler-10b: A Scorched World

The daytime temperature's expected to be more than 2,500 degrees Fahrenheit, hotter than lava flows here on Earth. Intense radiation from the star has kept the planet from holding onto an atmosphere. Flecks of silicates and iron may be boiled off a molten surface and swept away by the stellar radiation, much like a comet's tail when its orbit brings it close to the Sun.</div><br />Image Credit: NASA/Kepler Mission/Dana Berry<br />Explanation from: https://www.nasa.gov/mission_pages/kepler/multimedia/images/kepler10_3.html

Lenticular Galaxy NGC 4526

Its dark lanes of dust and bright diffuse glow make the galaxy appear to hang like a halo in the emptiness of space in this new image from the NASA/ESA Hubble Space Telescope.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">Although this image paints a picture of serenity, the galaxy is anything but. It is one of the brightest lenticular galaxies known, a category that lies somewhere between spirals and ellipticals. It has hosted two known supernova explosions, one in 1969 and another in 1994, and is known to have a colossal supermassive black hole at its centre that has the mass of 450 million Suns.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">NGC 4526 is part of the Virgo cluster of galaxies. Ground-based observations of galaxies in this cluster have revealed that a quarter of these galaxies seem to have rapidly rotating discs of gas at their centres. The most spectacular of these is this galaxy, NGC 4526, whose spinning disc of gas, dust, and stars reaches out uniquely far from its heart, spanning some 7% of the galaxy's entire radius.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">This disc is moving incredibly fast, spinning at more than 250 kilometres per second. The dynamics of this quickly whirling region were actually used to infer the mass of NGC 4526’s central black hole — a technique that had not been used before to constrain a galaxy’s central black hole.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">This image was taken using Hubble’s Wide Field Planetary Camera 2. </div><br />Image Credit: ESA/Hubble & NASA, Judy Schmidt<br />Explanation from: https://www.spacetelescope.org/images/potw1442a/

The Lagoon Nebula

<div style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2_xIeoU0w7k0uxv7YkHe7ND2VPM04FJkIj7q4UzsL8YFKy8oOKeC9EvDRV8__iRdvm-rrPgUvpvmCgIDtNpRaa_AaY9Hi8rvBVb3FnuAaDOyjKlqwW6dWj0pPqBDGUm63i66UTBiBuHYi/s1600/The-Lagoon-Nebula.jpg" imageanchor="1"><img alt="The Lagoon Nebula" border="0" height="323" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2_xIeoU0w7k0uxv7YkHe7ND2VPM04FJkIj7q4UzsL8YFKy8oOKeC9EvDRV8__iRdvm-rrPgUvpvmCgIDtNpRaa_AaY9Hi8rvBVb3FnuAaDOyjKlqwW6dWj0pPqBDGUm63i66UTBiBuHYi/s640/The-Lagoon-Nebula.jpg" title="" width="640" /></a></div><div style="text-align: center;"><br /></div><div style="text-align: center;">Like a Dali masterpiece, this image of Messier 8 from the NASA/ESA Hubble Space Telescope is both intensely colourful and distinctly surreal. Located in the constellation of Sagittarius (The Archer), this giant cloud of glowing interstellar gas is a stellar nursery that is also known as the Lagoon Nebula.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">Although the name definitely suits the beauty of this object, “lagoon” does suggest tranquillity and there is nothing placid about the high-energy radiation causing these intricate clouds to glow. The massive stars hiding within the heart of the nebula give off enormous amounts of ultraviolet radiation, ionising the gas and causing it to shine colourfully, as well as sculpting the surrounding nebula into strange shapes. The result is an object around four to five thousand light-years away which, on a clear night, is faintly visible to the naked eye.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">Since it was first recorded back in the 1747 this object has been photographed and analysed at many different wavelengths. By using infrared detectors it is possible to delve into the centre of these dusty regions to study the objects within. However, while this optical image, taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope, cannot pierce the obscuring matter it is undoubtedly one of the most visually impressive.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">Messier 8 is an enormous structure — around 140 by 60 light-years in extent — to put this in perspective the orbit of Neptune stretches only about four light-hours from our own Sun.</div><div style="text-align: center;"><br /></div><div style="text-align: center;">This picture was created from exposures taken with the Wide Field Channel of the Advanced Camera for Surveys on Hubble. Light from glowing hydrogen (through the F658N filter) is coloured red. Light from ionised nitrogen (through the F660N filter) is coloured green and light through a yellow filter (F550M) is coloured blue. The exposure times through each filter are 1560 s, 1600 s and 400 s respectively. The blue-white flare at the lower left of the image is scattered light from a bright star just outside the field of view. The field of view is about 3.3 by 1.7 arcminutes.</div><br />Image Credit: ESA/Hubble & NASA<br />Explanation from: https://www.spacetelescope.org/images/potw1120a/
