An optical-frequency image from the Legacy Surveys overlaid with radio emissions from the LoTSS survey, revealing the area of ​​the odd radio circle RAD J131346.9+500320

An article published in the journal “Monthly Notices of the Royal Astronomical Society” reports the discovery of three odd radio circles, including a pair cataloged as RAD J131346.9+500320. The discovery was made by examining data collected during the LOFAR Two-Metre Sky Survey (LoTSS) thanks to the collaboration of citizen scientists in the RAD@home program. A team of researchers examined these objects, and in particular, what appears to be a pair of intersecting rings, concluding that they’re the most distant discovered so far and that their emissions are the most powerful detected from these still poorly-known cosmic objects.

An article published in the journal “Astronomy and Astrophysics” reports the results of a study that provides evidence that a sort of giant cosmic wave is crossing the Milky Way, propagating from the center outward from the galactic disk, causing a corrugation. A team of researchers led by Eloisa Poggio of the Italian National Institute for Astrophysics used data collected by ESA’s Gaia space probe to map the motions of thousands of young giant stars and Cepheids within the corrugation, reconstructing the wave that generates them. The cause may be the aftermath of an ancient collision with a dwarf galaxy, but follow-up studies are needed to assess this and other possible explanations.

A little while ago, three space probes were launched atop a Falcon 9 rocket from the Kennedy Space Center. After approximately one hour and 23 minutes, they successfully separated from the rocket’s final stage within about 13 minutes and set off on a course that will take them to the area known as L1 (Lagrange 1), about 1.5 million kilometers from Earth, where they will begin their scientific work studying various aspects of space weather.

Northrop Grumman’s Cygnus XL spacecraft, launched last Monday, September 15, has just reached the International Space Station and was captured by the Canadarm2 robotic arm. Astronaut Jonny Kim, assisted by his colleague Zena Cardman, will soon begin the slow maneuver to move the Cygnus until it docks with the Station’s Unity module after about two hours.

A few hours ago, Northrop Grumman’s Cygnus XL spacecraft blasted off atop a SpaceX Falcon 9 rocket from Cape Canaveral on its NG-23 or CRS NG-23 mission. After about 15 minutes, it successfully separated from the rocket’s last stage and set on its course. This is the third resupply mission to the International Space Station with various payloads launched using the Falcon 9 rocket while waiting for the new version of Northrop Grumman’s Antares rocket to be ready. It’s also the first to see the use of the new version of the Cygnus cargo spacecraft.
