An image captured by the Hubble Space Telescope depicts R Aquarii, a binary system consisting of a red giant and a white dwarf. Four different filters of the WFC3 (Wide Field Camera 3) instrument were used in visible light to create the most recent observation of R Aquarii conducted with Hubble. This allowed to examine the changes that have occurred in particular in the nebula surrounding the pair.

The R Aquarii system is in the cosmic neighborhood, being about 650 light-years from Earth. For this reason, it has been the subject of study with different instruments since the two stars that make up the pair, which are invisible to the naked eye, were discovered. For example, it was the subject of a test using a subsystem of the SPHERE instrument installed on ESO’s VLT in Chile.

A few hours ago, NASA’s Europa Clipper space probe blasted off atop a SpaceX Falcon Heavy rocket from the Kennedy Space Center. After just over an hour, it successfully separated from the rocket’s last stage and set off on its route that will take it into deep space, to Europa, Jupiter’s moon with an icy surface that hides an ocean of liquid water to understand if it’s habitable.

SpaceX conducted a new flight test of its Super Heavy rocket and Starship prototypes, launched from its base in Boca Chica, Texas. This is the fifth test involving the entire system of Elon Musk’s company which is supposed to revolutionize space travel with an unprecedented transport capacity and being totally reusable. They are advanced prototypes with the Super Heavy identified as Booster 12 and the Starship identified as Starship 30 or Ship30 or simply S30.

Each test leads to new changes to the vehicles’ systems, and this was also true after the fourth test conducted on June 6, 2024. The scheduled breakthrough was in the test of the system called Mechazilla, the structure attached to the launch pad that also has the purpose of capturing the Super Heavy when it returns after launching the Starship.

An article accepted for publication in the journal “Monthly Notices of the Royal Astronomical Society” reports the discovery of a primordial galaxy that was cataloged as REBELS-25 and shows a rotating structure that is already ordered in a way that isn’t expected from such an ancient galaxy. A team of researchers used the ALMA radio telescope to study REBELS-25 and trace the movement of gas within it. The data collected will be invaluable in understanding how a galaxy that we see as it was when the universe was about 700 million years old can have a structure that is already becoming a spiral like the one of the Milky Way at that time.

Yesterday, ESA’s Hera space probe blasted off atop a SpaceX Falcon 9 rocket from the Cape Canaveral together with the two nanosatellites Juventas and Milani. After about 76 minutes, it successfully separated from the rocket’s last stage and set on its course which in almost exactly two years will take it to the asteroid Didymos and its moon Dimorphos to examine the consequences of the impact of NASA’s DART spacecraft.
