A team of astronomers has combined new observations of Gliese 667C with data from the HARPS instrument, installed on ESO's 3.6-meter telescope in Chile, to reveal the existence of a system with at least six planets. But what breaks all records is the fact that three of these planets are super-earths located in the area surrounding the star within which there could be liquid water, making them possible candidates for the presence of life.
A study led by researchers from the Higher Council for Scientific Research (CSIC) has revealed that about a ton of material from comet 21P / Giacobini-Zinner was deposited in the Earth's atmosphere on October 8 and 9, 2011, during one of the The most intense falling star showers of the last decade, which recorded an activity of just over 400 meteors per hour.
"A frenetic pace". This is how astronomers from the European Space Agency (ESA) describe the activity of a recently discovered very distant galaxy that manufactured stars at a rate 2,000 times that of the Milky Way when the Universe was less than a billion years old. The simple fact of its existence, discovered thanks to the Herschel space observatory, challenges current theories about the evolution of galaxies.
As explained by the Instituto de Astrofísica de Canarias (IAC), the minimum number is four (including eclipses of the Moon due to penumbra), two eclipses of the Sun, total or annular, and two eclipses of the Moon. This happened in 1999, 2003, 2005, etc.
On April 25 there will be a partial lunar eclipse that will be visible in Europe, Africa, Asia and Australia. It is a short-lived eclipse, which will begin at 7:54 p.m. and end at 8:21 p.m. in Universal Time (TU). The twilight eclipse will begin at 6:04 p.m. and end at 11:10 p.m. TU. Its obscuration will be limited, hence we speak of a penumbral eclipse, and the phenomenon can be seen without the need for any optical instrument.
From April 16 to April 25, both in the southern hemisphere and in the northern hemisphere you will be able to observe the meteor shower of the Lyrids. The meteors in this shower, whose number is unpredictable but are usually bright, come from the tiny particles of ice and rocks that it leaves in space on its journey around the Sun, the comet C / 1861 G1 (Thatcher), discovered in the year 186. Said comet takes approximately 415 years to revolve around the Sun, which is why it is considered a long period.

On March 13, 2013, the Atacama Large Millimeter / submillimeter Array, better known as ALMA, was officially inaugurated, an international telescopic installation that will revolutionize knowledge of the universe thanks to its gigantic antennas capable of detecting what the human eye does not see. Visit our photo gallery and learn more about this giant telescope.
