An article published in the journal “Science Advances” reports the first reconstruction ever of the shape of a Type II supernova in its early stages. A team of researchers led by Professor Yi Yang of Tsinghua University in Beijing, China, used observations conducted with ESO’s Very Large Telescope (VLT) in Chile to study the supernova cataloged as SN 2024ggi on April 11, 2024, the day after the explosion began.

A few hours ago, the Sentinel-1D satellite, part of the Copernicus / GMES, was launched from the Kourou spaceport, in French Guiana, atop an Ariane 6 rocket. After about 34 minutes, the satellite regularly separated from the rocket’s last stage and started sending signals. Its final orbit in low Earth orbit will be at an altitude of about 693 kilometers.

A confirmation has arrived that three Chinese taikonauts from the Shenzhou 21 mission reached the Chinese space station Tiangong with an automated docking maneuver. They blasted off about 3.5 hours earlier atop a Long March-2F rocket from the Jiuquan Satellite Launch Center. They form the 10th crew of the Chinese space station and will remain there for about six months, the standard duration for a mission.
