I expect there will eventually be a movie. 
 
#BREAKINGNEWS   African Court Convicts Captain of Renegade Ship in Illegal Fishing Case http://nyti.ms/1VOzsRO  via #NewYorkTimes   #OpIceFish  
A court in São Tomé and Príncipe convicted the captain and two crew members of the Thunder, the culmination of a chase from Antarctica to the Gulf of Guinea.

A modern naval chase the likes of whichhas not been seen since WW2.
For 110 days and across two seas and three oceans, crews stalked a fugitive fishing ship considered the world’s most notorious poacher.

Awesome!
 
New Computer Simulations Explain Observations Of HL Tauri
 In November 2014 we were amazed by the very first long baseline images of a baby solar system from the Atacama Large Millimetre/Submillimetre Array (ALMA).
Located in a nearby stellar nursery, the proto-planetary disc around the young star HL Tauri features a striking series of concentric, axisymmetric gaps, or rings, that can be explained by the presence of newborn planets.
Now a team of astronomers from Italy, Australia, and the UK have sought to explain the gaps seen in the ALMA long-baseline observations of the HL Tauri proto-planetary system.
Giovanni Dipierro, Daniel Price, Guillaume Laibe, Kieran Hirsh, Alice Cerioli and Giuseppe Lodato have found through extensive modelling and computer simulations that the observed gaps are explained by the different response of gas and dust to embedded planets in proto-planetary discs.
Astronomers have known for some years that planets can carve gaps in proto-planetary discs, but it has until now proved difficult to explain why HL Tauri does not exhibit the spiral pattern seen in other similar discs.
  Dipierro et al. performed global, three dimensional dusty smoothed particle hydrodynamics calculations of multiple planets embedded in dust/gas discs which successfully reproduce most of the structures seen in the ALMA image. Crucially, the scientists have found that their computer simulations explain the shape of the ALMA image because it shows a disc made of dust and not gas. Gaps carved in dust do not exhibit the spiral patterns that show up in observations of gas in young newly formed stellar systems.
They find a best match to the observations using three embedded planets with masses of 0.2, 0.27 and 0.55 MJ (Jupiter masses) in the three main gaps observed by ALMA.
There are however some remaining uncertainties in the exact planet masses from this disc model, so we can expect more observations and further modelling from astronomers keen to understand this nearby system of massive proto-planetary bodies caught in the act of forming planets.
On planet formation in HL Tau (2015) has been accepted for publication in MNRAS Letters and is available as a pre-print at :

These flicks were pretty crummy.

nice infographic of habitable zone vs age of sun for Sol and kepler-452.
 
Kepler 452b - A New Habitable Zone SuperEarth
Scientists have today (July 23rd 2015) announced the discovery of the planet Kepler 452b, found by astronomers using NASA's Kepler Space Telescope.
Kepler 452b is located 1400 light years away in the constellation of Cygnus. It is a "Super-Earth" some 60% larger than Earth, and orbits a sun-like Type G2 star once every 385 days. With a similar orbital distance to the Earth (Earth= 1AU, Kepler 452b= 1.05 AU) this new discovery is thought to be a rocky world but an exact mass and density has not yet been determined.
Importantly, Kepler 452b lies within it's star's habitable zone where water on the planet's surface will be in a liquid phase if present. It has therefore been called a "cousin Earth".
The animation shows that Kepler 452b has spent 6 billion years in the habitable zone, the planet and star being around 1.5 billion years older than our solar system.
Because stars slowly heat up and expand as they age, the Earth and this newly discovered world, will eventually be rendered uninhabitable due to warming by a runaway greenhouse effect.
