Comet dust flyover

Rosetta has imaged the smallest grains of Comet 67P/Churyumov-Gerasimenko’s dust yet, with its Micro-Imaging Dust Analysis System, MIDAS. The three-dimensional nature of five representative dust particles is visualised in this animation. It shows the complexity of the shapes of the dust particles, which are in turn made up of smaller and smaller dust grains.

In general, the particles are either classified as small, tightly packed ‘compact’ grains or larger more porous, loosely arranged ‘fluffy’ grains.

But, even though it may appear like we are flying over of a mountain range in this animation, these particles are extremely small: they range from a few tens of micrometres down to just a few hundred nanometres.

Hurricanes Madeline and Lester

The island of Hawaii rarely takes a direct hit from a hurricane. This week, two Pacific storms are lining up to change that. This natural-color image of Hurricane Madeline and Hurricane Lester is a composite built from two overpasses by the Visible Infrared Imaging Radiometer Suite on the Suomi NPP satellite on August 29, 2016.

Sentinel-1A fragment impact in space

The picture shows Sentinel-1A’s solar array before and after the impact of a millimetre-size particle on the second panel. The damaged area has a diameter of about 40 cm, which is consistent on this structure with the impact of a fragment of less than 5 millimetres in size.
