The introduction of fast 2D detectors and the use of very large telescopes have significantly advanced the sensitivity and accuracy of the lunar occultation technique. Recent routine observations at the ESO Very Large Telescope have yielded hundreds of events with results, especially in the area of binary stars, which are often beyond the capabilities of any other techniques. Aims. With the increase in the quality and in the number of the events, subtle features in the light curve patterns have occasionally been detected which challenge the standard analytical definition of the lunar occultation phenomenon as diffraction from an infinite straight edge. We investigate the possible causes for the observed peculiarities. Methods. We have evaluated the available statistics of distortions in occultation light curves observed at the ESO VLT, and compared it to data from other facilities. We have developed an alternative approach to model and interpret lunar occultation light curves, based on 2D diffraction integrals describing the light curves in the presence of an arbitrary lunar limb profile. We distinguish between large limb irregularities requiring the Fresnel diffraction formalism, and small irregularities described by Fraunhofer diffraction.

Venus and Mercury are the two inferior planets (planets that orbit between the Earth and the Sun). Their orbits are slightly inclined with respect to the Earth’s orbital plane but sometimes they pass in between the Earth and the Sun – this is called a transit. Dates for the next set of transits can be found here: http://eclipse.gsfc.nasa.gov/transit/transit.html When an object is eclipsed by another object in the sky it is called an occultation. Information about future occultations and all other celestial events can be found here: www.theguardian.com/science/series/starwatch Comets are balls of ice and rock that exist in two regions in the outer Solar System: the Kuiper Belt and the Oort Cloud. Occasionally they are knocked and are sent flying past the planets. When they reach the Sun the ice sublimates leaving behind a tail.

  • Water on the Moon, III. Volatiles & Activity
    Water on The Moon, III. Volatiles & Activity Arlin Crotts (Columbia University) For centuries some scientists have argued that there is activity on the Moon (or water, as recounted in Parts I & II), while others have thought the Moon is simply a dead, inactive world. [1] The question comes in several forms: is there a detectable atmosphere? Does the surface of the Moon change? What causes interior seismic activity? From a more modern viewpoint, we now know that as much carbon monoxide as water was excavated during the LCROSS impact, as detailed in Part I, and a comparable amount of other volatiles were found. At one time the Moon outgassed prodigious amounts of water and hydrogen in volcanic fire fountains, but released similar amounts of volatile sulfur (or SO2), and presumably large amounts of carbon dioxide or monoxide, if theory is to be believed. So water on the Moon is associated with other gases. Astronomers have agreed for centuries that there is no firm evidence for “weather” on the Moon visible from Earth, and little evidence of thick atmosphere. [2] How would one detect the Moon’s atmosphere from Earth? An obvious means is atmospheric refraction. As you watch the Sun set, its image is displaced by Earth’s atmospheric refraction at the horizon from the position it would have if there were no atmosphere, by roughly 0.6 degree (a bit more than the Sun’s angular diameter). On the Moon, any atmosphere would cause an analogous effect for a star passing behind the Moon during an occultation (multiplied by two since the light travels both into and out of the lunar atmosphere).

A conjunction is when two or more objects appear close to each other in the night sky. On the 31st of January, Mars, Venus, and the moon will all be in the western sky, setting together. Watch for this spectacular and rare event right after sunset between the 29th and the 2nd, with the best opportunity on the 31st of January. You do not even need a telescope! Juno continues mission around Jupiter Juno arrived at Jupiter earlier in July of 2016, marking a historic feat in space exploration. Having a few minor hiccups in some of the tech on the craft, it has been working fantastically and has already helped us understand the largest planet in our solar system more. The mission continues and more and more data comes pouring in every day. The data has already surprised astronomers, and there is so much to still learn from this mission. Some of our major understandings of Jupiter are being altered because of the data from this mission. Lightsail 2 launches: March The Planetary Society has been pioneering a new way of space flight: riding along the waves of space using the Sun's energy as power.

  • A Comparison of Astronomical Terminology and Concepts in China and Mesopotamia
    A Comparison of Astronomical Terminology and Concepts in China and Mesopotamia J. M. Steele, University of Durham 1. Introduction An interest in the movement and appearance of the sun, moon, planets and stars can be traced back in contemporary written sources to at least the Old Babylonian period in Mesopotamia (first half of the second millennium BC) and to the Shang dynasty in China (mid to end of the second millennium BC). In Mesopotamia, Old Babylonian cuneiform tablets contain omens drawn from the appearance of lunar eclipses (Rochberg 2006) and schematic lists of the length of day and night throughout the year (Hunger and Pingree 1989, pp. 163–164). In China, references to astronomical phenomena such as eclipses and comets appear on the so-called ‘oracle bones’ (Xu, Yau and Stephenson 1989; Xu, Stephenson and Jiang 1995). Except for so-called ‘star-clocks’ and related astronomical material from ancient Egypt, no contemporary writings on astronomical subjects are known from other cultures this early. Although cuneiform texts containing astronomical material are preserved from all periods in the second and first millennium BC, material is very scarce until the Late Babylonian period (c. 750 BC to AD 100), with the vast majority of texts coming from the last four centuries BC. A similar situation holds for China: after the Shang dynasty oracle bones we only have a very few documents containing astronomical records (principally the Zhushujinian 竹書紀年 ‘The Bamboo Annals’ and the Chunqui 春秋 ‘The Spring and Autumn Annals’) until the second century BC. After this time we have an extensive and continuous tradition of astronomical writings contained within the 25 Zhengshi 正史, generally referred to in English as the ‘Dynastic Histories’, and many individual books on astronomical topics, down to modern times.

The measurement was obtained from the analysis of a video of the eclipse flash spectrum recorded at the southern limit of the umbral shadow path. Our analysis was conducted by extracting light curves from the flash spectrum and comparing them to simulated light curves. Simulations were performed by integrating the limb darkening function (LDF) over the exposed area of photosphere. These numerical integrations relied upon very precise computations of the relative movement of the lunar and solar limbs.

  • Eclipse Observations Enabled by NASA's Lunar Reconnaissance
    National Aeronautics and Space Administration Eclipse Observations enabled by NASA’s Lunar Reconnaissance Orbiter Eclipse Observations enabled by NASA’s Lunar Reconnaissance Orbiter Data from NASA’s Lunar Reconnaissance Orbiter (LRO) is revolutionizing our understanding of the Moon. With LRO, we have found evidence of recent lunar volcanism. Some lava may have erupted onto the Moon’s surface only tens to hundreds of millions of years ago, instead of billions of years ago, as previously thought. We have found faults that indicate the entire Moon is shrinking! (Just a little bit, within the past few million years.) LRO has also witnessed changes on the Moon’s surface (including lots of new impact craters) since the mission began in 2009. Every day, this spacecraft is helping us better understand our nearest celestial neighbor, and processes that are occurring throughout the Solar System. You can learn more about these discoveries on LRO’s website, www.nasa.gov/lro. A B Thanks to LRO’s onboard laser altimeter and high-resolution cameras we know the shape of the Moon better than any other object in the Solar System – including Earth (since the majority of the Earth’s solid surface is under water). The top left image (A), shows the topography of the Moon, where cool colors represent low elevations and warm colors show areas with higher elevation. The blue line surrounding the Moon in the top right image (B) shows the outline of the Moon’s topographic profile, exaggerated 20 times. The bottom image shows an oblique view of the Orientale basin: an example of the rough topography found on the Moon.
