New research indicates vast voids in the extremely early universe did not contain large amounts of gas, blocking light from background galaxies. They actually contain little mass, with fewer nearby galaxies than expected.
NASA’s Chandra X-ray Observatory entered protective safe mode 10 October, the second of NASA’s “Great Observatories” to be sidelined in one week by a technical issue. Engineers are studying telemetry to pinpoint the problem.
Astronomers have found an “ultra-stripped supernova” that created a second neutron star in a tight binary system, matching theoretical predictions for how such binaries are formed in otherwise disruptive blasts.
The Hubble Space Telescope has been sidelined in the wake of problems with two of its four remaining gyroscopes. Engineers are hopeful they can restore one of the units to operation. If not, backup plans are in place.
Six years after the Voyager 1 spacecraft moved into interstellar space, Voyager 2 is detecting an increase in cosmic ray strikes indicating the probe is nearing the edge of the protective bubble defined by the Sun’s influence.
The International Astronomical Union, marking the 50th anniversary of the Apollo 8 mission that carried humans into lunar orbit for the first time in 1968, has named to craters to honour the historic mission.
Astronomers reviewing data collected by the planet-hunting Kepler spacecraft have found evidence for a large exomoon orbiting a gas giant 8,000 light years away. If confirmed, it would mark the first detection of a moon in another solar system.
Astronomers searching the outer solar system for signs of a super Earth-size world beyond Pluto have found another small body in an orbit consistent with the presumed gravitational influence of the presumed Planet X.
