The popularly known as "tears of San Lorenzo" can be seen with greater intensity on the night of August 12 to 13, once its radiant, located in the northeast direction, more specifically in the constellation of Perseus, rises on the horizon over the 23:30 (in the Canary Islands). The Moon will be in a crescent phase and will be hidden when the meteors begin to be seen, so it will not be an obstacle to their observation.

Using the Atacama Large Millimeter / submillimeter Array (ALMA), astronomers have obtained the first image of a snow line in a "baby" planetary system, specifically in the disk surrounding the solar-like star TW Hydrae. The finding promises to reveal new data on the formation of planets and comets, the factors that influence their composition and the history of our solar system.

Our Solar System is full of unsolved unknowns. Thanks to the technology of the Hubble telescope, they have just discovered the smallest moon that is orbiting Neptune.

The sky-blue exoplanet HD 189733b is 63 light-years away, a team of astronomers has just confirmed. Its bluish color is not due to large masses of water, as in the case of the Earth, but to the silicates that make up its atmosphere and that disperse the blue color giving it that chromatic tone similar to that of our planet.

Thanks to the Hubble Space Telescope, astronomers have been able to find out the true color of a planet orbiting a star other than the Sun. HD 189733b is a celestial blue color, chromatically similar to the appearance of the Earth seen from the outside. Are they alike in something else?

New observations in the microwave range carried out with the ALMA array (Atacama Large Millimeter / submillimeter Array) have provided astronomers with the best view yet of a gigantic star in the process of formation inside a dark cloud. known as the Spitzer Dark Cloud (SDC) 335.579-0.292. The embryonic star, located about 11,000 light-years away, greedily devours the material that falls into the cloud. It is believed that this cloud will give birth to a very bright star, with more than 100 times the mass of the Sun. Only one in ten thousand of all the stars in the Milky Way reach such a mass.

This is the name of the point in the Earth's orbit at which our planet is located farthest from the Sun. And it occurs because, in its displacement around the star, the Earth does not trace a perfect circular but elliptical path. The aphelion is reached in early July, in contrast to the perihelion or point of the Earth's orbit closest to the Sun, which takes place in January.

A team in which researchers from the Higher Council for Scientific Research (CSIC) participate has observed for the first time a new class of pulsating star, detectable by variations in its luminosity due to changes in its atmosphere, in our galaxy. The results, published in the latest issue of the journal Nature, open a new window for the study and understanding of the conditions in which low-mass white dwarfs form.
