In recent days, the Japanese Suzaku space observatory has been deactivated. On August 26, 2015, JAXA, the Japanese space agency, communicated the decision to terminate the mission of this satellite specialized in X-ray astronomy. Communications between the mission control center and Suzaku had become intermittent since June 1, 2015 and JAXA, after trying to restore them, decided to start the deactivation procedures.

An article in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the galactic cluster Abell 1033. Combining data from NASA’s Chandra X-ray Observatory, the Westerbork Synthesis Radio Telescope in the Netherlands, NSF’s Karl Jansky Very Large Array (VLA), and the Sloan Digital Sky Survey (SDSS), a team of astronomers reconstructed the history of a cloud of electrons at the cluster’s center. It was reignited after a cosmic collision and for this reason it’s been compared to the legendary phoenix.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research about the central region of the Milky Way. Using ESA’s XMM-Newton X-ray space observatory, a team of scientists from the Max Planck Institute for Extraterrestrial Physics (MPE) led by Dr. Gabriele Ponti revealed the most intense processes going on at the center of the galaxy.

A photograph of the galaxy NGC 428 taken by the Hubble Space Telescope shows its distorted and warped structure. Together with traces of a significant amount of stars being formed, it’s the sign of the merger between two galaxies. For this reason, its appearance could give us an idea of ​​what will happen in a few billion years to the Milky Way in its merger with Andromeda.

Planet 51 Eridani b is the first discovered using the Gemini Planet Imager (GPI), an instrument that started operating at the beginning of 2014 with the express purpose of directly detecting planets outside the solar system. This is the smallest exoplanet observed directly so far and its characteristics suggest that resembles Jupiter when it was very young. The results of this research were published in the journal “Science”.
