China lofts pulsar navigation demo satellite

November 10, 2016

China launched an innovative satellite Wednesday that will look for X-ray signals from pulsars, the fast-spinning super-dense remnants of collapsed stars, to determine its exact location in space.

Japan’s Hitomi observatory made cosmic discovery before failing

July 7, 2016

Japan’s doomed Hitomi observatory peeled back a veil on the inner workings of the Perseus cluster of galaxies before the satellite spun out of control earlier this year, revealing in unprecedented detail how gas heated to millions of degrees behaves around an unseen supermassive black hole, scientists said Wednesday.

LISA Pathfinder success bolsters plan for gravitational wave observatory

June 8, 2016

Europe’s LISA Pathfinder mission — a fundamental physics lab launched last year to a point a million miles from Earth — has demonstrated the mind-boggling technology required for a future space-based observatory to listen for faint, low-frequency vibrations emitted by invisible objects in the most distant pockets of the universe, scientists said this week.

Kepler adds 1,284 exoplanets to its total

May 10, 2016

A statistical analysis of data collected by NASA’s planet-hunting Kepler space telescope during its initial mission shows a better than 99 percent chance that 1,284 worlds previously classified as “candidates” are, in fact, actual planets, researchers said Tuesday.

Japan gives up on rescuing black hole observatory

April 29, 2016

Japan’s space agency says it has ceased efforts to rescue a failed X-ray astronomy satellite after it spun out of control and broke apart in orbit, declaring the nearly $400 million mission lost two months after its launch.

Kepler telescope recovered from spacecraft emergency

April 11, 2016

NASA’s Kepler spacecraft is stable and out of emergency mode, officials said Monday, and the observatory is downlinking data to help engineers determine what caused it to suspend science operations last week.

Kepler space telescope in emergency mode

April 9, 2016

Mission controllers are trying to diagnose a problem that put NASA’s Kepler planet-hunting observatory in emergency mode nearly 75 million miles from Earth this week.
