New Findings Show Some Type Ia Supernovae Linked to Novae

In the August 24 issue of the journal Science, astronomers for the first time show at least some that thermonuclear (Type Ia) supernovae eats from a regular nova. The results of the study, led by Ben Dilday, a postdoctoral researcher in physics at UC Santa Barbara and at Las Cumbres Observatory Global Telescope Network (LCOGT), are surprising because earlier indirect - but strong - evidence had pointed to the merger of two white dwarf stars as the Originators of Type Ia supernovae other.

NASA Curiosity Rover Begins Trek Eastbound on Martian Surface

NASA's Mars Curiosity rover has set off from its surrounding area landing on a trek to a science destination about a quarter mile (400 meters) away, where it may begin using its drill.

The rover drove eastward About 52 feet (16 meters) on Tuesday, its 22nd Martian day after landing. This third drive was longer than Curiosity's first two drives combined. The previous drives tested the mobility system and positioned the rover to examine an area scoured by exhaust from one of the Mars Science Laboratory spacecraft engines That Placed the rover on the ground.

Dawn spacecraft leaves asteroid Vesta and the dwarf planet Ceres flies

The Dawn spacecraft is on its method to become the first spacecraft that orbited two remote celestial bodies of the solar system and studied. Dawn is on 5 September after over one year orbit around Vesta and leave this in 2.5 years to fly to the dwarf planet Ceres. Even these celestial bodies should examine Dawn at close range. The probe is expected in February 2015 in Ceres. Dawn launched on 27 September 2007. The end of the mission is scheduled for July 2015.

The high solar activity is manifested by numerous sunspots

Planets

Mars honored us only briefly in the evening sky. He's in the evening to see just for an hour in the West South West. Mars is 1.2 Size bright and is located in the constellation Virgo.

The Ring Planet Saturn adopted soon by the evening sky. He can only be seen for an hour in the West South West (set at 21 ½ clock). Saturn (0.8 size) Located in the constellation Virgo. Saturn has an angular distance (elongation on) from the sun of 44 °.

The Sun in September 2012

On 22 September is around 16:49 EST, the astronomical start of autumn. The sunset is the end of September an hour earlier than the first of the month - to 19 ¼ clock. Also in the morning, it is much longer dark: The sunrise is delayed until after 7 clocks.

The sundial reflects the true solar time, which can be determined from the position of the sun in our sky by direct measurements.

The moon in September 2012

On 22 September, the moon is half-lit and is particularly low in the sky: it is the southernmost of the decreasing half-moon of the year. New Moon is on the 16th September. The observation of the first crescent of the new moon and last time in the bright twilight is sometimes a challenge, especially in this month: Both events are theoretically to see only part of the German-speaking world and then only with the aid of optical means.

Planets in September 2012

While Saturn’s visibility in the evening sky ended, escapes Mars just barely the bright sunlight and remain inconspicuous in the dusk. Jupiter Sunrise's premature to late evening hours. Until the rising of Venus at 3 clock the gas giant Jupiter is the brightest star-like object in the sky. Venus reached in September, the highest level in the dawn of the morning current visibility and dominates the morning sky as a very bright “morning star ".
