An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a study of the exoplanet 55 Cancri e. It claims that on its surface there’s and extremely violent volcanic activity. The consequence is that the temperature is not only very high but has swings ranging from 1,000° to 2,700° Celsius (from 1800° to 4900° Fahrenheit). Among the authors of the article there’s Dr. Nikku Madhusudhan of British Institute of Astronomy of the British University of Cambridge, who has been studying 55 Cancri e for some time and has already published a study in which he argues that this exoplanet may contain a diamond large three times the Earth.
Roscosmos, the Russian space agency, announced that the Progress M-27M spacecraft disintegrated in an uncontrolled reentry in the Earth’s atmosphere. Officially, the cargo space has ceased to exist at 02.04 UTC of Friday falling over the Pacific Ocean. It was the inevitable conclusion of a mission that started badly on April 28, 2015, with a serious problem that had caused the impossibility to take control of the Progress to send it to the International Space Station, where it was supposed to bring supplies.
Last October a picture of the system HL Tauri captured by ESO’s ALMA (Atacama Large Millimeter / submillimeter Array) telescope was published. It showed a disk of dust that is slowly coalescing and was one of the sharpest images ever made at sumbillimetric wavelengths. According to many scientists there are planets that are forming in the system but others were skeptical and that created a debate. Now a team of astrophysicists from the University of Toronto led by Daniel Tamayo brought new evidence that there really are planets forming, published in the journal “Astrophysical Journal”.
NASA announced Journey to Mars, a challenge in which the public was invited to submit ideas to develop the elements needed to establish a permanent presence of humans on the planet Mars. There are the basic elements to sustain human life, meaning shelter, food, water, breathable air but also communications, exercise, social interaction, and medicine. Other elements can be considered as well because a true colony must be able to go beyond basic needs to thrive.
Between April 28 and 29, 2015 a solar flare produced a filament that spread to a really huge distance. The result is that the images of the space probe SOHO (Solar and Heliospheric Observatory) that captured the filament, to include it cover a wide area of 45 million kilometers (about 30 million miles).
