On November 2, 2000, the first three crew members reached the International Space Station to begin their work in what was then the new outpost of humanity. With that act, American astronaut Bill Shepherd and Russian cosmonauts Sergei Krikalev and Yuri Gidzenko established a continuous human presence there. Over the years, the Station has been expanded to take its current configuration developing wider and wider opportunities to do research that have brought and will bring various technological and scientific developments.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the detailed observation of a huge X-ray eruption by a supermassive black hole known as Markarian 335 or Mrk 335. The Swift and NuSTAR space telescopes were used to examine this phenomenon of gigantic proportions concluding that it originated from a coronal ejection.

An article published in “Astrophysical Journal Letters” describes a new analysis of the data collected by NASA’s Voyager 1 space probe to understand why certain detections were abnormal. Voyager 1 entered interstellar space in 2012 but the unclear data raised discussions. After about a year, NASA confirmed the event but some unexpected characteristics of the solar system borders required further studies.

An article just published in the journal “Nature” describes the discovery of oxygen molecules in the coma of the comet 67P/Churyumov-Gerasimenko. It’s a surprising discovery, and in fact is the first time that this presence is detected in a comet because molecular oxygen is very reactive so it tends to combine for example with hydrogen to form water. This oxygen is a “survivor” from the time of formation of the solar system.

An article published in recent days in the journal “Science” describes research that has used the technique of asteroseismology to estimate the intensity of the magnetic fields in the vicinity of the cores of some red giants. This allowed to establish that their intensity can also be 10 million times greater than the Earth’s magnetic field. It’s the first time that scientists have been able to investigate within this type of star.
