Hunting for planets

This new array will focus in the search for planets the size of Neptune and smaller, with a diameter of two to eight times that of the Earth. Reach a level of accuracy in the measurement of the brightness of stars – one part in a thousand – than ever before. Credit: ESO/G. Lambert The

Three planets for a red dwarf

© Afrim Constantin –

EPIC 201367065, is a red dwarf M-class (the coldest), has about half the size and mass of our sun and is located at “just” 150 light years from Earth. The outermost planet, once it is half the radius of Earth’s orbit far enough away from its star, receiving levels of light from its parent star

Cassini-Huygens and Titan

The descent of the probe lasted about two hours before it hit the cold ground of Titan, from which continued to broadcast for another hour before the batteries ran out. Even on Huygens, as Cassini, the Italian instrumentation is not missing. Eleven years ago, on 14 January 2005, the Cassini spacecraft, a collaboration of three

Chondrules – the origin of planets?

© Afrim Constantin –

Collisions between planetary embryos, the “seeds” of the primordial planets of the solar system, would be the process that gave birth to the mysterious chondrules – drops of molten rock before they solidified – present in meteorites. The research is published in Nature. If confirmed, it is one of those discoveries that will force to

How quasars influence the evolution of galaxies

© Afrim Constantin –

Astronomers have explored the most remote regions of space to study how quasars, among the brightest sources of the Universe, influence the evolution of galaxies. The numerical simulations relating to the dynamics of the gas which is ejected at high speed from the central regions of the quasar are consistent with observations obtained, in particular,

The focus is on Pluto

© Afrim Constantin –

Two or more planets yet unknown beyond the orbit of Pluto could be responsible for that shaped in a particular way the trajectories of some remote celestial objects, known as ETNO (Extreme Trans-Neptunian Objects). These are the results of a study just published in the Monthly Notices of the Royal Astronomical Society journal. The caution

Spiral arms of Milky Way

© Afrim Constantin –

According to a study conducted by a group of Chinese astronomers, one of the spiral arms of the Milky Way, known as Shield-Centaur arm, could extend much further than assumed, wrapping all the way around our galaxy. It would hold a rare event ever observed in other spiral galaxies nearby. Since our solar system resides

Mr. Big, 500 meters asteroid

© Afrim Constantin –

It is expected on Monday, January 26th, the apex of a flyby between 2004 BL86 – an asteroid of 500 meters – and our planet. For an object of this size, it will be the closest approach between now and 2027. It will reach magnitude 9, visible even with amateur equipment. Never seen an asteroid
