Seeing double could help resolve dispute about how fast the universe is expanding
At the heart of the dispute is the Hubble constant, a number that relates distances to the redshifts of galaxies — the amount that light is stretched as it travels to Earth.

Astronomers find that the sun’s core rotates four times faster than its surface
Scientists had assumed the core was rotating at about the same speed as the surface, but this surprising observation might reveal what the sun was like when it formed.

Astronomers observe a dying red giant star’s final act
An international team of astronomers has observed a striking spiral pattern in the gas surrounding a red giant star called LL Pegasi and its companion star 3,400 light-years from Earth.

Experiment resolves mystery about wind flows on Jupiter
UCLA’s Jonathan Aurnou and collaborators in Marseille, France, demonstrated that the planet’s jets likely extend thousands of miles below its visible atmosphere.
-
The moon is older than scientists thought, UCLA-led research team reports
A UCLA-led research team reports that the moon is at least 4.51 billion years old and probably formed only about 60 million years after the birth of the solar system — 40 million to 140 million years earlier than had been thought.

A planet 1,200 light-years away is a good prospect for a habitable world
Kepler-62f could have atmospheric compositions that allow it to be warm enough to have surface liquid water, which would make it possible for the planet to support life.
-
Astronomers confirm faintest early-universe galaxy ever seen
The researchers made the discovery using an effect called gravitational lensing to see the incredibly faint object, which was born just after the Big Bang.
