In run-up to Halloween, ESA jokes about “spooky sight” in space. Sense of humour aside, the view is spectacular
The star that pierces through the ‘fog’ is V380 Orionis, a bright, young star, JUST LIKE YOU. It is 3.5 times the mass, and with its surface temperature of about 10 000ºC, two times as hot as our Sun. Literally white hot. So young it is still surrounded by a cloud of material left over from its formation.
ESA’s Photographs of August’s total solar eclipse, both from the Earth’s surface and space, are rather spectacular
As ESA explains, total eclipses are made possible by a quirk of our cosmos: the Moon’s average distance is just right for it to appear as the same size in the sky as the Sun. Though the Sun’s diameter is 400 times that of the Moon’s, it is also 400 times further away from the Earth.
Cool. ESA’s Sentinel-3A satellite maps Ireland-bound Hurricane Ophelia’s speed, temperature, water and ice content
One of the forces of nature capable of being tracked, satellites provide up-to-date information on a storm’s extent, wind speed and path, as well as key features such as cloud thickness, temperature, and water and ice content. This allows precautionary measures to be taken.
Originally planned for one Martian year (687 days), it has been in operation for more than 13 years, still sending to Earth valuable scientific data, as well as photographs of out-of-this-world beauty.
‘Set your controls for the heart of the sun’: ESA mission to send Space Craft to the sun for detailed study
“Solar Orbiter’s over-arching mission goals are to examine how the Sun creates and controls the heliosphere, the extended atmosphere of the Sun in which we reside, and the effects of solar activity on it.”
