The first day of northern summer began with a solar flare. Magnetic fields above sunspot complex 1236 erupted during the early hours of June 21st, hurling a coronal mass ejection (CME) almost directly toward Earth. The incoming CME does not appear to be particularly potent; nevertheless, the cloud could trigger polar geomagnetic storms when it reaches Earth on or about … Read the rest of this article

What Messier Objects Are Visible Tonight
June 21, 2011
What Messier Objects Are Visible Tonight ()?
A list of messier objects visible this month. All are possible with binoculars, most are easy even with small binoculars.
Over 1.5 million kilometres from Earth, ESA’s Herschel space telescope has been observing the Universe for the last two years, studying the infrared radiation emitted by the coldest bodies in the cosmos. See the invisible in this video.

Phobos and Jupiter Conjunction
June 17, 2011
Earlier this month, ESA’s Mars Express performed a special manoeuvre to observe an unusual alignment of Jupiter and the martian moon Phobos. The impressive images have now been processed into a movie of this rare event.
At the moment when Mars Express, Phobos, and Jupiter aligned on 1Â June 2011, there was a distance of 11Â 389 km between the … Read the rest of this article
Total Lunar Eclipse Tonight (June 15)
June 15, 2011
Tonight, June 15th, there’s going to be a total lunar eclipse that’s visible from every continent except North America (sorry guys!). The Moon will spend 100 minutes fully engulfed in Earth’s shadow, making this the longest lunar eclipse in nearly 11 years. The appearance of the eclipse might be affected by exhaust from Chile’s erupting Puyehue-Cordón Caulle volcano, which is … Read the rest of this article
On 8 June, mission controllers had the first opportunity to switch ESA’s Rosetta comet-hunter into deep-space hibernation for 31 months. During this loneliest leg of its decade-long mission, Rosetta will loop ever closer toward comet 67-P, soaring to almost 1000 million km from Earth.
Marking one of the most dramatic and distant … Read the rest of this article
ESA and NASA have announced the scientific investigations selected for their 2016 ExoMars lander demonstrator. They will probe the atmosphere during the descent, and return the first ever data on electrical fields at the surface of Mars.

NASA’s Voyager probes are truly going where no one has gone before. Gliding silently toward the stars, 9 billion miles from Earth, they are beaming back news from the most distant, unexplored reaches of the solar system.
Mission scientists say the probes have just sent back some very big news indeed.
It’s bubbly out there.
“The Voyager probes appear to … Read the rest of this article
Massive Solar Eruption
June 9, 2011
Yesterday morning (June 7th) around 06:41 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The blast produced an M2-class solar flare, an S1-class radiation storm, and a massive CME. A recording of the blast from NASA’s solar Dynamics Observatory ranks as one of the most beautiful and dramatic movies of the SDO era. This video of the … Read the rest of this article
Springtime at Mars’ South Pole
June 7, 2011
ESA’s Mars Express celebrates eight years in space with a new view of ice in the southern polar region of Mars. The poles are closely linked to the planet’s climate and constantly change with the seasons. Their study is an important scientific objective of the mission.
