Dark matter is slowing the spin of the Milky Way's galactic bar
The spin of the Milky Way's galactic bar, which is made up of billions of clustered stars, has slowed by about a quarter since its formation, according to a new study by researchers at University College London (UCL) and the University of Oxford.
For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured.
The researchers say it gives Boundary of heliosphere mapped for the first time
For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact.
"Physics models have theorized this boundary for years," said Dan Reisenfeld, a scientist at Los Alamos National Laboratory and lead author on the paper, which was published in the Astrophysical Journal today. "But this is the first tim Ultra-cool test of Jupiter instrument

An instrument destined for Jupiter orbit undergoes eight days of cryogenic radio-frequency testing using a new test facility at ESA’s ESTEC technical centre in the Netherlands. The Submillimetre Wave Instrument of ESA’s Juice mission will survey the churning atmosphere of Jupiter and the scanty atmospheres of its Galilean moons.
Testing took place in ESA’s custom-built Low-temperature Near-field Terahertz chamber, or Lorentz. The first chamber of its kind, the 2.8-m diameter Lorentz chamber can perform high-frequency radio-frequency testing in realistic space conditions, combining space-quality vacuum with ultra-low temperatures.
SMC stands up new Space Safari program office
Space Safari responds to high-priority, urgent space needs by rapidly acquiring, integrating and executing missions in support of USSPACECOM requirements and other combatant commander needs. These missions are not typically a part of an enduring program of record, but respond to high priority needs to deploy space systems quickly to respond to emerging threats.
As a high-speed integrator SkyWatch raises $17.2 million in Series B funding round

SAN FRANCISCO – SkyWatch Space Applications raised 20.9 million Canadian dollars ($17.2 ) in a Series B funding round, less than 17 months after welcoming investors to its Series A round.
The rapid pace of fundraising was not in the Canadian startup’s original plan but necessitated by demand for TerraStream, a data management and distribution platform SkyWatch offers Earth-observation companies.
