Images from 15 to 11 now in the ESO Top 100 Images series. The 360-degree Panorama of the Southern Sky is amazing – just look how alive The Milky Way is as it arches across the night sky.

Our astro advent calendar image count-down returns to Earth for today’s image, but that doesn’t mean it’s any less striking.
If any type of image can better demonstrate the apparent movement of the stars across the sky I’ve not seen one yet!
Day 16
Astronomy Advent Calendar 16th December - This startrail image shows the movement of the stars over an evening (click to enlarge) - Credit: Iztok Bončina/ESO
The stars rotate around the southern celestial pole during a night at ESO’s La Silla Observatory in northern Chile. The fuzzy parts in the trails on the right are due to the Magellanic Clouds, two small galaxies neighbouring the Milky Way.
The dome seen in the image hosts ESO’s 3.6-metre telescope and is home to HARPS (High Accuracy Radial velocity Planet Searcher), the world’s foremost exoplanet hunter.
Swirly!

And there’s us thinking NASA’s Kepler telescope rules the roost over exoplanet hunting!
Today astronomers in La Silla, Chile announced a fertile haul of more than 50 new exoplanets – the latest results using ESO’s exoplanet hunter HARPS (High Accuracy Radial velocity Planet Searcher). The haul includes 16 super-Earths, one of which orbits at the edge of it’s habitable zone around its star. By studying the properties of the planets found so far, the ESO team have discovered that around 40% of stars similar to our Sun have at least one planet lighter than Saturn.
Lead author Dr Michel Mayor, from the University of Geneva in Switzerland, said the haul included “an exceptionally rich population of super-Earths and Neptune-type planets hosted by stars very similar to our Sun”.
He added: “The new results show that the pace of discovery is accelerating.”
One of the recently announced newly discovered planets, HD 85512 b, is estimated to be only 3.6 times the mass of the Earth and is located at the edge of the habitable zone.
“This is the lowest-mass confirmed planet discovered by the radial velocity method that potentially lies in the habitable zone of its star, and the second low-mass planet discovered by HARPS inside the habitable zone,” says Lisa Kaltenegger (Max Planck Institute for Astronomy, Heidelberg, Germany and Harvard Smithsonian Center for Astrophysics, Boston, USA), who is an expert on exoplanets habitability.
Astronomers are confident they are close to discovering other small and rocky habitable planets around stars similar to our Sun. Moving forward new instruments are planned to further the search and include a copy of HARPS to be installed on the Telescopio Nazionale Galileo in the Canary Islands, to survey stars in the northern sky, as well as a new and more powerful planet-finder, ESPRESSO, to be installed on ESO’s Very Large Telescope in 2016. Looking further into the future the planned CODEX instrument on the European Extremely Large Telescope (E-ELT) will push this technique to a higher level.
Wouldn’t it be great to wake up one morning to a fresh Sky-Watching post actually detailing a habitable planet! I guess by then we could just beam the information directly to your brain!

Well there’s no mention or images of the new Supernova spotted in a nearby galaxy in this weeks post or indeed any in any relating to this series. Nonetheless we resume the countdown with the (latest) positions 50-46*.
