A few hours ago the Astrosat space observatory was launched on a PSLV-XL rocket from the Satish Dhawan Space Centre in the flight listed as PSLV-C30 by ISRO, the Indian space agency. After about 22 minutes Astrosat regularly separated from the rocket’s upper stage to enter an orbit close to the equator at an altitude of about 650 kilometers (about 400 miles). Along with it six satellites were launched for customers of different nations: the Indonesian Lapan-A2 microsatellite, the Canadian NLS-14 (EV9) microsatellite and four USA LEMUR nanosatellites.
An article in the journal “Monthly Notices of the Royal Astronomical Society” describes a study of the galaxy SAGE0536AGN and in particular the supermassive black hole at its center, which is 30 times larger than expected. This is the result of measurements conducted by a team of astronomers at Keele University and the University of Central Lancashire, an anomaly all to explain.
The Chinese government announced its intent to enter into a new phase of its involvement in the development project of the SKA radio telescope by signing a letter of intent with the SKA Organisation that runs it.
