The ESA/NASA SOHO satellite watched as Comet ISON made its closest approach to the Sun on 28 November, at a distance of around 1.2 million kilometres from the Sun’s visible surface. Did it survive? Early reports suggested that only the comet’s tail continued to follow along ISON’s orbit. Further observations will reveal if a chunk of the comet’s nucleus survived.

Comet ISON on the approach to the Sun. It entered the SOHO LASCO C3 field of view at 01:41 UT on 27 November. This video covers over 24 hours of the journey so far. Will ISON survive its closest approach with the Sun? Stay tuned: http://soho.esac.esa.int/hotshots/index.html/

Two coronal mass ejections (CMEs) expand side-by-side from the Sun and out into space in this movie, playing out in front of the ESA/NASA Solar and Heliospheric Observatory, SOHO, on 1-2 July 2013.
The shaded disc at the centre of the image is a mask in SOHO’s LASCO instrument that blots out direct sunlight to allow study of the faint details in the Sun’s corona. The white circle added within the disc shows the size and position of the visible Sun.

Read the full experiment at http://www.stevespanglerscience.com/experiment/solar-oven-s-mores There are just some things that are synonymous with “summertime snacks,” and we can’t think of a summer snack we enjoy quite as much as s’mores. But what would you do if you weren’t allowed to have a fire or just didn’t have the tools necessary for a fire? We came up with a pretty neat way to harness the heat and energy of the sun to create a solar powered cooker that makes a delicious batch of s’mores without a fire!

ESA’s space weather microsatellite Proba-2 observed the solar eclipse on the evening of 20 May 2012. It passed through the Moon’s shadow a total of four times, imaging a sequence of partial solar eclipses in the process. The first contact was made on Sunday May 20 at 21:09 GMT. The last contact finished at 03:04 GMT.

Mercury has always been something of a puzzle for planetary scientists. Its close position to the Sun means it is very difficult to observe, but now a series of satellites is getting up close to this fascinating planet. The European Space Agency’s BepiColombo mission is among them, and it will offer an unprecedented level of information about the mysterious world of Mercury.
Sie haben die Größe einer Waschmaschine, doch sie beschaffen wertvolle Informationen bei der Beobachtung der Erde und der Sonne. Die Rede ist von Mikrosatelliten mit dem Namen Proba.
Comets are primeval leftovers from the origins of the Solar System. To fully understand these ancient objects and perhaps the origins of life on Earth, ESA’s Rosetta mission will rendezvous with comet Churyumov-Gerasimenko in 2014. In November of that year, Rosetta’s Philae lander will touchdown on the comet and thoroughly investigate its composition.

Space missions are complicated pieces of orbital choreography. When planning a mission, spacecraft engineers must calculate how to point the solar panels towards the Sun, the main antenna towards Earth and the instruments towards the target. ESA Space Scientist Detlef Koschny build a LEGO model of Rosetta mission in order to visualise these precise orientations.

Built using LEGO Mindstorms, the Philae lander model can be controlled using a home computer. It can rotate and move the drill up and down to simulate the behaviour of the real lander. As part of ESA’s Rosetta space mission, Philae will land on comet Churyumov-Gerasimenko in November 2014 to study its composition.
