The dust fades the alien presence in the Tabby star

For months, astronomers have been closely following the mystery of Tabby’s star, whose brightness varies sporadically in a strange way. For a time it was thought that a large extraterrestrial structure could be behind the phenomenon but the most likely cause are dust clusters, according to the latest observations.

Discovered the poorest massive stars in metals known to date

The study of the primitive universe necessarily involves understanding the functioning of the first stars that, according to the simulations of star formation, could be very massive. In this context, understanding the evolution of massive stars is key to interpreting the processes of star formation that took place in the…

Solving the mystery of the white spots of Ceres

The spots indicate that there is some kind of geological process underway. They can not be made of pure ice because at the distance that Ceres del Sol is, the ice is unstable and sublimates in a short time. It was concluded that they were salt deposits. But what kind?…

Giant storms cause palpitations in Saturn’s atmospheric heartbeat (ENG)

The atmospheres of the Earth, Jupiter and Saturn show a remarkably similar phenomenon in their equatorial regions: vertical, cyclic patterns, descending alternate temperatures and wind systems that repeat over a period of several years. These patterns, known as Quasi Periodic Oscillation (QPO) in Saturn and Quasi-Quadriennial Oscillation (QQO) in Jupiter,…

Does the Juno probe suffer from the strange anomaly of the overflight?

One of the mysteries of current astronautics is the so-called ‘flyby anomaly’. This name is given by the strange acceleration experienced by some probes when performing a gravitational assist maneuver to change its speed around the Sun. The difference between the predicted speed and the measured speed is almost negligible,…
