    A number of extrasolar planets have been found in the past two decades and now researchers agree that planets can have a wide variety of characteristics.
    However, it is still unclear how this diversity emerges. Especially, there is still debate about how the icy giant planets, such as Uranus and Neptune, form.

    To take a close look at the planet formation site, a research team led by Takashi Tsukagoshi at Ibaraki University, Japan, observed the young star TW Hydrae.
    This star, estimated to be 10 million years old, is one of the closest young stars to the Earth. Thanks to the proximity and the fact that its axis of rotation
    points roughly in the Earth's direction, giving us a face-on-view of the developing planetary system, TW Hydrae is one of the most favorable targets for
    investigating planet formation.

    A Novel Approach to Studying a Star's Environment from Light Curvessu201640 | www.cfa.harvard.edu/
    https://www.cfa.harvard.edu/news/su201640

    There are now about 2700 confirmed exoplanets discovered by transiting techniques including those used with the Kepler satellite.
    The transit method observes the stellar light curve (the flux versus time), and spots the slight dimming of starlight when an exoplanet
    crosses the face of the star as seen from Earth. The orbital period of the exoplanet can be determined from multiple transits, with the
    duration and details of the transit dip providing a measure of the planet's size. Light curves actually monitor a number physical processes
    including some at the stellar surface (like sunspots) as well as in their surroundings. Periodic variability of the observed stellar flux
    has long been used to measure stellar rotation periods, for example; transiting exoplanets produce a characteristic shape in the light curve.

    Uranus might have two dark moons we've never seen before | New Scientist

    Uranus may have two small moons that no one has ever seen, orbiting closer to the planet than any
    of its other satellites and making wavy patterns in the planet’s rings.

    Observable Universe contains ten times more galaxies than previously thought
    http://phys.org/news/2016-10-universe-ten-galaxies-previously-thought.html

    Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census
    of the number of galaxies in the Universe. The group came to the surprising conclusion that there are at least 10 times
    as many galaxies in the observable Universe as previously thought. The results have clear implications for our understanding
    of galaxy formation, and also help solve an ancient astronomical paradox—why is the sky dark at night?

    Chicxulub 'dinosaur crater' investigation begins in earnest - BBC News
    http://www.bbc.com/news/science-environment-37625348

    Scientists have obtained remarkable new insights into the asteroid impact that wiped out the dinosaurs.
    They have been examining rocks from the crater that the 15km-wide space object dug out of what is now the Gulf
    of Mexico some 66 million years ago.
    The team says it can see evidence in these materials for how life returned to the scene soon after the calamity.
    Descendants of these small organisms are likely thriving today in amongst the crater's smashed up materials.
    The international project has shipped the hundreds of metres it drilled from beneath the Gulf floor earlier
    this year to the MARUM Center for Marine Environmental Sciences, at the University of Bremen, Germany.
    It is here that the cores are being catalogued, analysed and archived.

    Cosmological mystery solved by largest ever map of voids and superclusters
    http://m.phys.org/news/2016-10-cosmological-mystery-largest-voids-superclusters.html

    A team of astrophysicists at the University of Portsmouth have created the largest ever map
    of voids and superclusters in the universe, which helps solve a long-standing cosmological mystery.

    The map of the positions of cosmic voids – large empty spaces which contain relatively few galaxies –
    and superclusters – huge regions with many more galaxies than normal – can be used to measure the effect
    of dark energy 'stretching' the universe.

    The results confirm the predictions of Einstein's theory of gravity.
