Schroter's Valley

Schroter's Valley, frequently known by the Latinized name Vallis Schröteri, is a sinuous valley or rille on the surface of the near side of the Moon. It is located on a rise of continental ground, sometimes called the Aristarchus plateau, that is surrounded by the Oceanus Procellarum to the south and west and the Mare Imbrium to the northwest. At the southern edge of this rise are the craters Aristarchus and Herodotus.

This is the largest sinuous rille on the Moon. It begins at a 6 km diameter crater located 25 km to the north of Herodotus. (The start of the rille has been termed the "Cobra's Head" by some observers, due to its resemblance to a snake.) From the crater it follows a meandering path, first to the north, then setting a course toward the northeast, before finally bending back to the south until it reaches a 1 km high precipice at the edge of the Oceanus Procellarum. The rille has a maximum width of about 10 km, then gradually narrows to less than a kilometer near its terminus.

The origins of this rille are believed to be volcanic. The interior floor has been resurfaced and is very level. However there is a slender rille located on the floor, which can be photographed from Earth with a good telescope and good seeing.

The rille has been the subject of numerous transient lunar phenomena observations.

The selenographic coordinates of this valley are 26.2°N 50.8°W, and it has a maximum diameter of 168 km. It is named for Johannes H. Schröter.

It was a potential landing site for the canceled Apollo 18 mission

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.[11] It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows.[12] Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°.

Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. However, it has also been shown to be radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercury is closer to the Sun. Venus has no carbon cycle that puts carbon into rock, nor does it seem to have any organic life to absorb carbon in biomass. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have possessed oceans in the past,[13][14] but these would have vaporized as the temperature rose due to a runaway greenhouse effect.[15] The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind.[16] Venus' surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism

C/2014 Q2 (Lovejoy) _15-1-2015

C/2014 Q2 (Lovejoy) is a long-period comet discovered on 17 August 2014 by Terry Lovejoy using a 0.2-meter (8 in) Schmidt–Cassegrain telescope.[1] It was discovered at apparent magnitude 15 in the southernconstellation of Puppis.[1] It is the fifth comet discovered by Terry Lovejoy.

By December 2014, the comet had brightened to roughly magnitude 7.4,[4] making it a small telescope and binoculars target. By mid-December, the comet was visible to the naked eye for experienced observers with dark skies and keen eyesight.[5] On 28−29 December 2014, the comet passed 1/3° from globular cluster Messier 79.[6] In January 2015, it brightened to roughly magnitude 4−5,[7] and became one of the brightest comets located high in a dark sky in years. On 7 January 2015, the comet passed 0.469 AU (70,200,000 km; 43,600,000 mi) from Earth.[8] It crossed the celestial equator on 9 January 2015 becoming better seen from thenorthern hemisphere.[9] The comet will come to perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU (193,000,000 km; 120,000,000 mi) from the Sun.[2]

Before entering the planetary region (epoch 1950), C/2014 Q2 had an orbital period of about 11000 years.[3] After leaving the planetary region (epoch 2050), it will have an orbital period of about 8000 years.[3]

COMET ISON C/2012_S1 ANIMATION

Comet Ison C/2012_S1 animation November 9 2013

C/2012 S1, also known as Comet ISON or Comet Nevski–Novichonok, is a sungrazing comet discovered on 21 September 2012 by Vitali Nevski (Виталий Невский, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок,Kondopoga, Russia).[5] The discovery was made using the 0.4-meter (16 in) reflector of the International Scientific Optical Network near Kislovodsk, Russia and the automated asteroid-discovery program CoLiTec.[2][6] Precovery images by the Mount Lemmon Survey from 28 December 2011 and by Pan-STARRS from 28 January 2012 were quickly located.[7] Follow-up observations were made on 22 September by a team from Remanzacco Observatory in Italy using the iTelescope network.[2][8] The discovery was announced by the Minor Planet Center on 24 September.[7] Observations by SWIFT suggest that C/2012 S1's nucleus is around 5 kilometers (3.1 mi) in diameter.[9]

C/2012 S1 will come to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun.[3] Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 will pass approximately 1,165,000 km (724,000 mi) above the Sun's surface.[10] Its trajectory appears hyperbolic, which suggests that it is a dynamically new comet coming freshly from the Oort cloud.[11][12]On its closest approach, C/2012 S1 passed about 0.07248 AU (10,843,000 km; 6,737,000 mi) from Mars on 1 October 2013, and it will pass about 0.4292 AU (64,210,000 km; 39,900,000 mi) from Earth on 26 December 2013.[13]

Shortly after its discovery, similarities between the orbital elements of C/2012 S1 and the Great Comet of 1680 led to speculation that there might be a connection between them.[14] However, further observations of ISON showed that the two comets are not related.[15]

Earth will pass near the orbit of C/2012 S1 on 14–15 January 2014, well after the comet has passed, at which time micron-sized dust particles blown by the Sun's radiation may cause a meteor shower or noctilucent clouds.[16][17]However, both events are unlikely. Because Earth only passes near C/2012 S1's orbit, not actually through the tail, the chances that a meteor shower will occur are slim.[18] In addition, meteor showers from long period comets that make just one pass into the inner solar system are very rare, if ever recorded.[19] The possibility that small particles left behind on the orbital path—almost one hundred days after the nucleus has passed—could form noctilucent clouds is also slim. No such events are known to have taken place in the past under similar circumstances.[19]

Crater Copernicus

Copernicus is a lunar impact crater named after the astronomer Nicolaus Copernicus, located in eastern Oceanus Procellarum. It is estimated to be about 800 million years old, and typifies craters that formed during the Copernican period in that it has a prominent ray system.
