S.A.M. (the Sample Analysis at Mars)

© Afrim Constantin –

A mineral was identified which, when heated, destroys organic compounds. The discovery, published in Astrobiology, could have consequences for the NASA’s rover, Curiosity for future missions, like ExoMars, dedicated to the search for traces of life on the Red Planet. The culprit is called SAM. It had been sent to Mars to hunt for signs

The super wind that sweeps Galaxy

© Afrim Constantin –

The international team of astronomers led by Emanuele Nardini and INAF studied the properties of the mighty wind emitted by the supermassive black hole at the center of a galaxy by measuring, for the first time, the intensity and also revealing the spreading of the black hole in all directions. The work is published in

The first maneuver of ‘immersion’ of MAVEN

© Afrim Constantin –

The first programmed maneuver of ‘immersion’ was successfully completed to allow the probe MAVEN to collect data on the state of the Martian upper from a close distance. “The usual mappings are able to take measurements from a distance that is between 150 and 6200 km from the surface,” says Bruce Jakosky, principal investigator for

New look for Titan

© Afrim Constantin –

A new algorithm was developed to reduce electronic interference in the photos taken by the Synthetic Aperture Radar. The technique is called despeckling and comes 10 years after the arrival of the Cassini spacecraft on Saturn’s orbit. Finally, the images will be sharper and useful. When a probe is launched into orbit there are many

The Black holes – The existence of warm absorbers

© Afrim Constantin –

Here is the identikit of the so-called “warm absorbers”, the layers of ionized plasma remotest among those issued, in galaxies to active nucleus, the central black hole. What could be simpler than a black hole? It is an object so uniform that describing it should be like a walk. But if the black hole in

Special effects or reality?

© Afrim Constantin –

The software used to create images of the black hole in the last film by Christopher Nolan is so effective that it has given us the most detailed vision that could experience a person, if it could orbit around this extreme object. The team in charge of the special effects of the film by Christopher

Rosetta is making history

© Afrim Constantin –

On February 14, the Rosetta probe has touched the comet 67P flying over just 6 km from the surface. Today, February 16, 2015, ESA has released some images, with a resolution of 0.76 meters per pixel, taken from the Navigation Room during the phase of maximum approach. Never reached so close: just 6 km. So

Kepler-432B

© Afrim Constantin –

It is one of the densest planets ever discovered: it has the same size of Jupiter, but six times its mass. And it is a planet from doom: its parent star, a red giant, between 200 million years will engulf it relentlessly. A giant planet, extremely rare, the extreme seasons and that day – or
