Rosetta is getting close and Comet 67P/Churyumov-Gerasimenko looks to be a very good choice. The since the previous image release on 4 July, Rosetta as reduced its distance to the comet by 25,000 km (to 12,000 km from 35,000 km).

Description from ESA:
Comet 67P/Churyumov-Gerasimenko was imaged on 14 July 2014 by OSIRIS, Rosetta’s scientific imaging system, from a distance of approximately 12 000 km. This image has been processed using ‘sub-sampling by interpolation’, a technique that removes the pixelisation and makes a smoother image. It does not, however, reveal hidden detail and it is therefore important to note that the comet’s surface is not very likely to be as smooth as the processing implies. The image suggests that the comet may consist of two parts: one segment seems to be rather elongated, while the other appears more bulbous.

I had to, it’s like the biggest sporting event going and I’m not about to miss out! YAY football!

ESA’s Planck satellite gets the Milky Way’s magnetic fingerprint. Image: ESA
The ESA Planck satellite took this image of polarized light emission from interstellar dust. The darker regions (as you can read below) are the more strongly polarized. I am a little surprised by the amount of polarization away from the galactic equator, I thought it would have been more uniform. The full report will be coming out later this year.
Polarized light has been coming up quite frequently in different stories as of late.
Here’s the full explanation from ESA.
The ESA short version:
The magnetic field of our Milky Way Galaxy as seen by ESA’s Planck satellite. This image was compiled from the first all-sky observations of polarised light emitted by interstellar dust in the Milky Way. The magnetic field is displayed using a visualisation technique called line integral convolution (LIC).
Darker regions correspond to stronger polarised emission, and the striations indicate the direction of the magnetic field projected on the plane of the sky. The dark band running horizontally across the centre corresponds to the Galactic Plane. Here, the polarisation reveals a regular pattern on large angular scales, which is due to the magnetic field lines being predominantly parallel to the plane of the Milky Way. The data also reveal variations of the polarisation direction within nearby clouds of gas and dust. This can be seen in the tangled features above and below the plane, where the local magnetic field is particularly disorganised.
The image is a Mollweide projection of the full celestial sphere, with the plane of the Galaxy aligned with the horizontal axis of the oval. Certain areas in the image, mostly at high Galactic latitude, have been masked out. The overall intensity in these regions is low, complicating the separation of foreground and CMB components. Further data analysis will improve this by the time of the full data release in late 2014.

I want to see the Goldfish. Ok I spent five minutes looking for it until I re-read the press release and the bit about it being just out of view. Larger and full-res versions availble at the link below.
BTW, I LOVE the title from ESA for selfish reasons. LOL.
From ESA Spaceinimages (The Tadpole and the Wriggler):
A bright blue tadpole appears to swim through the inky blackness of space. Known as IRAS 20324+4057 but dubbed “the Tadpole”, this clump of gas and dust has given birth to a bright protostar, one of the earliest steps in building a star.
There are actually multiple protostars within this tadpole’s ‘head’, but the glowing yellow one in this image is the most luminous and massive. When this protostar has gathered together enough mass from its surroundings, it will eventually emerge as a fully-fledged young star.
Watch this! They (Airanespace) call it remarkable, I call that an understatement! This is astounding is what it is.
One of the many really cool video showing up recently.
This from Arianespace:
Remarkable images from on-board cameras provide a detailed “ride-along” view of Arianespace’s Flight VS07, which orbited Europe’s Sentinel-1A from the Spaceport in French Guiana.
Recorded during the 23-minute mission on April 3, multiple cameras covered the action from final countdown to separation of the mission’s payload.
The Arianespace/European Space Agency/Roscosmos-copyrighted video begins with the pre-launch steps as seen from two cameras – mounted on opposite sides of the medium-lift launcher.
Looking down from the launcher’s upper portion, the opening sequence includes separation of umbilical connections for Soyuz’ Fregat upper stage, followed by the tilt-back of two umbilical masts. One of these masts provides fluids and electrical connections for the launcher’s Block I third stage, while the second mast services the Soyuz vehicle’s Block A core stage.
Soyuz’ engine ignition is clearly seen in the video with the startup sequence for the first stage’s four boosters and central core second-stage. This is followed by liftoff and the opening of four arms that supported the vehicle while on the pad – and which are opened by Soyuz’ upward movement.
