Before NASA’s Kepler mission searched for exoplanets using the transit method, there was the European COROT mission, launched in 2006. It was sent to search for planets with short orbital periods and find solar oscillations in stars. It was an incredibly productive mission, and the focus of today’s show.

 The presently known largest small bodies in the Kuiper Belt are likely not to be surpassed by any future discoveries. This is the conclusion of Dr. Michael Brown, et al. (Illustration Credit: Larry McNish, Data: M.Brown) The self-professed "Pluto Killer" is at it again. Dr. Michael Brown is now reminiscing about the good old days when one could scour through sky survey data and discover big bright objects in the Kuiper Belt. In his latest research paper, Brown and his team have concluded that those days are over. Ten years ago, Brown discovered what is now known as the biggest Kuiper Belt object – Eris. Brown's team found others that rivaled Pluto in size and altogether, these discoveries led to the demotion of Pluto to dwarf planet. Now, using yet another sky survey data set but with new computer software, Brown says that its time to move on. (...)

 Close-up of comet 67P on January 3, 2015, showing the larger of the two lobes (boulder Cheops labelled), multiple jets of dust, and what are most likely dust particles or aggregates in the comet’s coma or atmosphere. Click to enlarge. Credit: ESA/Rosetta/NAVCAM Anyone who’s ever read a Charlie Brown comic strip knows “Pig-Pen”, the lovable boy who walks around in a constant cloud of his own dirt and dust. Every time he sighs, dust rises in a little cloud around him. Why bother to bathe? There’s dignity in debris, which “Pig-Pen refers to as the “dust of countless ages”. Comets shuffle around the Sun surrounded by a similar cloud of grime that’s as old as the Solar System itself.(...)

Moons pass by Saturn’s rings. An eclipse takes place on Jupiter. We see these shots every day in images from space agencies, but how would it be to actually float in a nearby spacecraft and watch these in action? An incredible new Vimeo video called “Space Suite” shows off what it actually could be like. And here’s the neat thing — it is heavily based on those very same jaw-dropping shots space agencies regularly release. (...)

 SpaceX Falcon 9 rocket lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station, FL, carrying the Dragon resupply spacecraft to the International Space Station. Credit: John Studwell/AmericaSpace "Huge strides towards [rocket] reusability" were achieved, says SpaceX CEO Elon Musk, following Saturday morning's (Jan. 10) flawless launch of his firm’s Falcon 9 rocket on a critical resupply mission to the space station for NASA, which also had a secondary objective of recovering the booster’s first stage via an unprecedented precision-guided landing on an ocean-going "drone."

 This object is a stowaway on board New Horizons. Credit: JHU/APL The New Horizons spacecraft is now just a few months away from its encounter with Pluto and the Kuiper Belt, arriving in July, 2015. Back in 2008, the New Horizons team revealed the secret stowaways they had hidden on board the spacecraft. Nine objects (can you guess why there are nine?!) were attached and sent along on the ten-year journey to the outer reaches of our Solar System. Believe it or not, included in the items are one actual person, and parts of several thousands of other people… (...)

 This photo map shows Comet Lovejoy’s nightly position among the winter stars through January 19th as it travels across the constellation Taurus not far from Aldebaran and the Pleiades star cluster. Click to enlarge. Credit: Bob King Comet Q2 Lovejoy passed closest to Earth on January 7th and has been putting on a great show this past week. Glowing at magnitude +4 with a bluish coma nearly as big as the Full Moon, the comet’s easy to see with the naked eye from the right location if you know exactly where to look. I wish I could say just tilt your head back and look up and bam! there it would be, but it’ll take a little more effort than that. But just a little, I promise. (...)

 You couldn’t miss Mercury and Venus together last night January 9th 45 minutes after sunset in the southwestern sky. Very easy to see! They’ll be even closer tonight. Credit: Bob King As Universe Today’s Dave Dickinson described earlier this week not only has Venus returned to the evening sky, but Mercury has climbed up from the horizon to join it. Last night (Jan. 9th) the two planets were separated by just a hair more than one Moon diameter. The photo only hints at amazingly easy the pair was to see. Consider the duo a tasty hors d’oeuvres before the onset of night and the Comet Lovejoy show.(...)
