ESA's Rosetta spacecraft has made its first temperature measurements of its target comet, finding that it is too hot to be covered in ice and must instead have a dark, dusty crust.

With the incredible images of comet 67P/Churyumov-Gerasimenko's nucleus grabbing most of the attention over the last few weeks, we shouldn't forget about the comet's coma.

In this week's images, taken on 20 July from a distance of 5500 km, comet 67P/Churyumov-Gerasimenko's largest features are beginning to stand out in the OSIRIS narrow angle camera view.

This week's images of comet 67P/Churyumov-Gerasimenko reveal an extraordinarily irregular shape. We had hints of that in last week's images and in the unscheduled previews that were seen a few days ago, and in that short time it has become clear that this is no ordinary comet.

What a difference a week can make. Even in the six days since the last image, the shape of comet 67P/Churyumov-Gerasimenko is becoming much more apparent, although still heavily pixelated.

Rosetta's scientific imaging system OSIRIS is slowly but surely resolving comet 67P/Churyumov-Gerasimenko in its narrow angle camera (NAC), giving the first tantalising hints of its shape.

ESA's Rosetta spacecraft has found that comet 67P/Churyumov–Gerasimenko is releasing the equivalent of two small glasses of water into space every second, even at a cold 583 million kilometres from the Sun.

An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects.

The target of ESA's Rosetta mission has started to reveal its true personality as a comet, its dusty veil clearly developing over the last six weeks.

ESA's Rosetta spacecraft has caught a first glimpse of its destination comet since waking up from deep-space hibernation on 20 January.
Published: 27 March 2014
Following last week's wake-up of the Rosetta comet-chaser, ESA's flight controllers have conducted the first in a series of health checks aimed at assessing how well it came through 31 months of hibernation.

It was a fairy-tale ending to a tense chapter in the story of the Rosetta space mission this evening as ESA heard from its distant spacecraft for the first time in 31 months.

On 20 January 2014, ESA's comet-chasing Rosetta spacecraft is set to wake up from 957 days in deep-space hibernation. A day-long event will be held at ESA's European Space Operations Centre to mark this momentous occasion. Follow the programme online.

Think it's tough getting up in the morning when the alarm clock sounds? Imagine what it must be like waking up 673 million kilometres from the warmth of the Sun and with no coffee. You might need some help...

ESA's comet-chasing mission Rosetta will wake up in 100 days' time from deep-space hibernation to reach the destination it has been cruising towards for a decade.

The long and tumultuous history of asteroid (21) Lutetia is revealed by a comprehensive analysis of the data gathered by ESA's Rosetta spacecraft when it flew past this large main-belt asteroid on 10 July 2010.
Published: 29 May 2012
On 10 July 2010, ESA's Rosetta spacecraft flew past asteroid Lutetia, one of the largest objects orbiting within the main asteroid belt between Mars and Jupiter. Rosetta's encounter revealed an intriguing object which has survived since the birth of the planets.
