New study of gamma rays and gravitational lensing points to the possible presence of dark matter.
- Analyzing data from the Fermi Gamma-ray Space Telescope, researchers find hints of dark matter.
- The scientists looked to spot a correlation between gravitational lensing and gamma rays.
- Future release of data can pinpoint whether the dark matter is really responsible for observed effects.
Astronomers find these five chapters to be a handy way of conceiving the universe's incredibly long lifespan.
- We're in the middle, or thereabouts, of the universe's Stelliferous era.
- If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
- Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.
And the first sci-fi weapon the Space Force gets is....a device to scramble communications?
- The United States Space Force recently got its first real weapon, a satellite communications jammer.
- The device was previously used by the Air Force.
- While seemingly mundane, the jammer will serve a very real purpose on the battlefield.
The ESO finds another exoplanet that's definitely not a place for us to go.
- WASP-76b is an extremely hot planet whose cooler side has a surface temperature of 1,500° C (2732° F).
- Iron that evaporates in the heat of the planet's day side rains down in molten form on the night side.
- ESO learned more about the planet's intense climate thanks to its new ESPRESSO (Echelle Spectrograph for Rocky Exoplanet and Stable Spectroscopic Observations) instrument.
A mission is planned for just three weeks from now, but NASA has a plan.
- Before liftoff on every mission since 1971, NASA crew members spend two weeks in a "health stabilization" quarantine.
- Other employees of the agency have been given a response framework that tells them where and how to proceed with their duties.
- For upcoming launches, NASA is depending on Russia and SpaceX to step up to the challenge.
