Pictures from the Lunar Eclipse expedition in Peru – DE


Here are two shots summarising the Lunar Eclipse of April 15th, 2014. On the left, a frame from a starryearth.com video shot from the top of the Teide vulcano (see this YouTube video) with its shade pointing exactly to the partially eclipsed Moon (the small white spot at the head of the triangular dark zone). On the right the spectacular composition of the entire eclipse observed by a magic site, suspended between past and present: the access gate of the Inca fortress of Sacsayhuaman, place located North of Cusco, during the GLORIA project expedition to Peru.

Lunar eclipse from the land of the Inca – DE


On April 15th, 2014 the moon will be eclipsed by the shadow of the earth. This marks the first of four eclipses occurring about 6 months part, called an eclipse tetrad. The last tetrad was a decade ago, and the next is not due until 2032.
The best eclipse visibility will be from North America and parts of South America. A team of GLORIA astronomers will celebrate this astronomical spectacle with a live broadcast from the city of Cusco, Peru, in the Sacred Valley of the Incas. Throughout Europe, totality will not be visible. However the Teide volcano, at 3718m altitude on the island of Tenerife, offers an intriguing observational prospect. When a total lunar eclipse occurs close to sunrise or sunset at Teide, the shadow of the volcano aligns perfectly with the eclipsed moon. This unique phenomenon will be observable during the eclipse of April 15th and will be broadcast live.

SN2014J – supernova in M82 – DE

The nearest type Ia supernova in 400 years has been found in the Messier 82 (M82) galaxy. First spotted on 21 January 2014, it is relatively close to Earth, about 11.4 million light years away!
This supernova is called SN2014J (the 10th supernova discovered so far during 2014), and is a rare kind. „Type Ia“ supernovae (SNe) are believed to be caused by exploding white dwarf stars. These SNe explode with very predictable brightnesses, making them ideal ’standard candles‘ to measure distances to galaxies accurately.

Now that it has reached maximum brightness, around Jan 31 (with a magnitude in the R band of about 10), GLORIA will keep monitoring the SN2014J light-curve (along with other supernovae) for the next few months as part of the regular program conducted by some of the GLORIA partners. Indeed, many astronomical observatories worldwide (including space-borne facilities) will point to this unique target regularly over the coming weeks.

Personal Space, the sky «I like» – DE

Geminids
The birthday for someone, the graduation day for someone else. The day of your first kiss, or your first day of employment, or maybe the day of your last cigarette. Our lives are punctuated by memorable moments. But how was then the sky right above your head?

Personal Space” is there to answer the question. It is a free web-based application developed within the GLORIA project by a team of astronomers lead by Robert Simpson (University of Oxford) and Lorraine Hanlon (University College Dublin), and an artist, Emer O Boyle (University College Dublin). Personal Space turns the celestial sphere into a huge, boundless social network. Establishing direct and personal connections to the universe by linking significant events in your own life with what was above you in the sky at that moment. And with people all around the world who shared that portion of the sky with us.

„I am an astronomer, I have lots of reasons for looking at different bits of the sky. But what is the bit of the sky that is most obvious for people to look at? I am told by non-astronomer friends that you want to look directly up», said Robert Simpson. «So what is directly above my head right now? That is the idea behind Personal Space».

Gaia on its way to L2 – DE

Gaia on its way to L2, taken by Pi of the Sky in Huelva (Spain) on the 19th evening. Stack of 30 images of 10 second exposure each.

ESA’s Gaia mission is aimed to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of 1% of the total population of roughly 100 billion stars, it will answer questions about the origin and evolution of our home Galaxy. The Soyuz launcher, operated by Arianespace lifted off at 09:12 GMT on Dec 19 with Gaia on board. A few hours after, one of the GLORIA telescopes, the Pi-of-the-Sky-North experiment at the BOOTES-1 astronomical station at ESAt/INTA-CEDEA in Huelva (Spain), recorded the spacecraft on its route towards an orbit around a gravitationally-stable virtual point in space called L2, some 1.5 million kilometres from Earth in the direction opposite to the Sun.
