Fierce flashes of light ripple through delicate tendrils of gas in this new image, from ESA’s Herschel space observatory, which shows the dramatic heart of a large and dense cosmic cloud known as Mon R2. This cloud lies some 2700 light-years away and is studded with hot, newly-formed stars.
Packed into the bright centre of this region are several hot ‘bubbles’ of ionised hydrogen, associated with newborn stars situated nearby. Here, gas heated to a temperature of 10 000 °C quickly expands outwards, inflating and enlarging over time. Herschel has explored the bubbles in Mon R2, finding them to have grown over the course of 100 000 to 350 000 years.
This image from ESA’s Space in Images shows the planetary nebular Abell 78. The faint hydrogen “bubble” of the nebula is around 1.4 light years across, the inner envelope of helium has resumed fusion – it’s reborn.

Beneath the vivid hues of this eye-shaped cloud, named Abell 78, a tale of stellar life and death is unfolding. At the centre of the nebula, a dying star – not unlike our Sun – which shed its outer layers on its way to oblivion has, for a brief period of time, come back to echo its past glory.
The Philae lander is alive and well on Comet 67P/Churyumov–Gerasimenk and is sending data packets back to ESA’s European Space Operations Centre in Darmstadt.
The lander has 24 watts available and is “ready for operations” according to DLR Philae Project Manager Dr. Stephan Ulamec.
The transmissions lasted 85 seconds when Philae “spoke” via the Rosetta spacecraft for the first time since 15 November 2014 when Philae shut down after about 60 hours of operation. Rosetta has been listening for signals from Philae since 12 March 2015.
Check out the Rosetta blog for more information. THIS IS EXCELLENT!!!!
The image shows the journey of the Philae lander captured by the Rosetta OSIRIS camera for a 30 minute span. The lander was to have landed and stayed put but that didn’t work as planned and the actual location wasn’t immediately apparent. Link to ESA image description – it’s more complete.

ESA, France’s space agency CNES and the German aerospace centre DLR inaugurated the Airbus A310 ZERO-G refitted for altered gravity by running 12 scientific experiments this week.
The French company Novespace has conducted “parabolic flights” for more than 25 years. By flying the parabolic patterns at around 50 degrees up and down a brief period of weightlessness is created at the top of the curve. As the plane comes “over the top” forces on everything in the plane (people included) cancels out and weightlessness is achieved for a brief period.
We’ve all see the videos, what I seldom thought about is what happens at the bottom of the curve. When the plane “bottoms out” and starts climbing the forces on everything in the plane is about 2G.
This particular plane is new being acquired in 2014 replacing an Airbus A300. You won’t find many seats in the passenger area, you will find padded walls so people do not get hurt during the weight/weightless cycles, sick maybe, but not hurt.
