Now that well over 100 planets have been discovered, we no longer need to ask the question "Are there planets out there?" ... The objective of XO is to find additional hot-Jupiters (like HD 209458b) that transit stars bright enough for detailed follow-up studies to be done with existing telescopes such as HST, Keck, and the VLT. ... Transit observations by themselves provide no information about the mass of the planet and radial velocity studies can yield only minimum masses. ...

... Long before humankind evolved, before dinosaurs roamed, and even before our Earth existed, ancient globs of stars condensed and orbited a young Milky Way Galaxy. Colors of Comet Pojmanski . ... Unexpected Comet Pojmanski Now Visible . ... Comets bright enough to be visible to the unaided eye appear only every few years. ... Peering deep inside Centaurus A, the closest active galaxy to Earth, the Spitzer Space Telescope's penetrating infrared cameras recorded this startling vista in February 2004. ...

... Any water on Mars is locked up in the ice caps. ... The most recent successful mission to Mars is the Mars Science Laboratory better known as the Curiosity rover. ... CuriosityтАЩs primary role is to search for conditions that may have once been able to harbour any sort of bacterial life concealed beneath the Martian surface. ... Using what we know about life on Earth, where there is water, there is life, signs of water may help us understand what Mars was like billions of years ago. €а . ...

... The Moon is steadily moving up and up. ... Earth loses angular momentum because the high tide closest to the Moon is trying to get back directly underneath the Moon, while the high tide farthest from the Moon is trying to get as far away from the Moon as possible. ... Therefore, Solon would still experience some tides and its rotation would still slow down, but not nearly by as much as Earth's. Solon's day would be around eight hours long at this time in its life, 4.6 billion years after it formed. ...

... It s sometimes hard to grasp the length of time involved in events in the Universe. But the Universe is huge and it has been around for a very long time 13.7 billion years! ... These big time scales mean that astronomers can t study something like the lifetime of a star by studying one star, as that would take millions or billions of years! ... Sometimes, though, things that are far away in deep space change in the night sky during our lifetime. Take this new space photo, for example. ...

New data from NASA's Interstellar Boundary Explorer (IBEX) shows that the heliosphere moves through space too slowly to form a bow shock. ... New results from NASA's Interstellar Boundary Explorer (IBEX) reveal that the bow shock, widely accepted by researchers to precede the heliosphere as it plows through tenuous gas and dust from the galaxy, does not exist. ...

Detecting Long Period Planets with WASP 1 University of Warwick, Gibbet Hill Road, Coventry, CV4 7AL To estimate the number of transiting planets in this period range, planetary occurrence rates from Kepler (Fressin et al, 2013) for varying spectral type & planet type were used. ... Two `stare' fields are currently available from 2011 (330,000 stars) producing a detection rate of 3.0±2.4 planets (Fig 4). ... Since 2011, WASP-N cameras have observed in `Stare' mode, with cadence of ~1-2min. ...

Just beyond the main asteroid belt there exists a population of small objects orbiting the Sun at the same heliocentric distance of Jupiter. The combined action of Jovian and Solar gravity creates a stable dynamical haven for these objects near the so-called Lagrangian equilibrium points, in honour to the French mathematician Joseph Louis Lagrange who first demonstrated their existence and stability. ... Soon after its discovery it was realized that this asteroid is, in fact, a Mars Trojan. ...

... 8, ``Celestial Mechanics'', 2002 Regularity and chaos for planetary orbits in binaries D. Benest Observatoire de Nice, Nice, France 1. ... Previous papers showed that stable planetary orbits, around either the lightest or the heaviest component of several nearby binary systems, exist up to distances from their primary of the order of more than half the binary's periastron sep­ aration. ... Chaos: bounded or sticky? It is now well­known that planetary dynamics may include some proportion of chaos. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

In a game of ping-pong, suppose a paddle moves at 20 miles per hour and hits a ball with 20 mph in the opposite direction. ... In the new problem, a ball moving at -40 mph hits a non-moving surface; if the collision is elastic (no energy lost), that ball returns with the same speed but in the opposite direction, i.e. its velocity reverses sign. ... Something very similar happens when a spacecraft with velocity v passes close to a moving planet and is deflected. ...

... The apparent path of the Sun across the sky. ... Like the planets, the Sun, too, moves around the zodiac, making one complete circuit each year. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...
