New clues suggest how Hot Jupiters form
Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative age of hot Jupiters using new measurements from the Gaia spacecraft, which is tracking more than a billion stars.
Lead author Jacob Hamer, a P Sun-like star identified in the region where the Wow! Signal originated
On May 6, the International Journal of Astrobiology of Cambridge University Press published a paper titled 'An approximation to determine the source of the Wow! Signal', authored by Alberto Caballero, a Spanish astronomer and science communicator.
Caballero decided to search through a catalog of stars from the European Space Agency's Gaia satellite to look for possible candidates.
He iden Astra rocket fails to deliver 2 small satellites after launch, NASA says
NASA said a rocket carrying two small weather satellites failed Sunday, preventing the inauguration of a technology that would have helped better forecast hurricanes.
The rocket by California-based Astra lifted off from Florida's Cape Canaveral Space Force Station, but the rocket's second stage malfunctioned before reaching orbit and lost the shoebox-sized technology.

Ariane 6 cryogenic disconnection systems pass key tests

00:00:39
ESA’s new Ariane 6 heavy-lift rocket is a critical step closer to inaugural launch, following completion of tests to validate launch pad/launcher systems that will keep the vehicle topped up with liquid hydrogen and liquid oxygen in the critical moments before liftoff.
While on the launch pad at Europe’s Spaceport in French Guiana, Ariane 6 relies on a “cryogenic connection system” of umbilical cords carrying its hydrogen and oxygen fuel – liquified at -250C and -180C respectively – as well as helium and nitrogen used for flushing and purging. The tests seen in this video showed that retraction
NASA loses two hurricane monitoring satellites on launch
Two small NASA satellites that were meant to study hurricane development failed to enter orbit Sunday when their Astra rocket shut off before reaching the necessary altitude, the US space agency said.
"After a nominal first stage flight, the upper stage of the rocket shut down early and failed to deliver the TROPICS CubeSats to orbit," NASA's Launch Services Program said on Twitter.
In a post to its website before the launch, NASA described the TROPICS CubeSats as a constellation of six "shoe-box sized" satellites that will "study the formation and development of tropical cyclones, making observations more often than what is possible with current weather satellites.
Galileo – a new tool for science
Every moment of every day, Europe’s constellation of Galileo navigation satellites that ring our planet transmits precisely shaped and timed signals, down through the atmosphere, reflecting back from Earth’s land, seas and ice and extending far out into space, as far as the Moon.
