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.
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 new study rocks prevailing theories on antimatter in the early Universe.
- Scientists from around the world teamed up to study the properties of neutrons.
- They were able to achieve extremely precise measurements of electric compasses in neutrons.
- The results challenge current theories of why antimatter and matter didn't destroy each other in the early Universe.
A new batch of papers reveals some of Mars' subterranean secrets.
- The spacecraft InSight detected tremors from deep underneath the rust-colored surface of Mars indicating, for the first time ever, that the planet is geologically active.
- The quakes could potentially give seismologists insights into the interior composition of the planet.
- The Insight lander also uncovered magnetized rocks "consistent with a past dynamo with Earth-like strength" under the surface of the landing sight.
