Blaming a slew of technical snags and “avoidable errors,” NASA officials said Tuesday that the launch of the James Webb Space Telescope, already years behind schedule, will be delayed to 2020, potentially pushing the mission’s development cost above an $8 billion cap mandated by Congress.

Kepler Space Telescope sheds light on fast-evolving supernovae

26 March 2018 Astronomy Now

NASA’s Kepler Space Telescope has captured a difficult-to-detect, fast-evolving supernova in the act of blowing up and rapidly fading away, allowing astronomers to rule out competing theories and come up with a plausible explanation.

A mission proposed by a British-led science team to investigate the atmospheres of planets around other stars has been selected by the European Space Agency for launch in the late 2020s, officials announced this week.

Interstellar asteroid ‘Oumuamua likely originated in binary star system

19 March 2018 Astronomy Now

The interstellar asteroid ‘Oumuamua likely originated in a binary star system, researchers say. The rocky, cigar-shaped asteroid was discovered last October as it made a high-speed pass through Earth’s solar system.

Radio echoes of a black hole feasting on a doomed star

19 March 2018 Astronomy Now

Astronomers studying emissions from a black hole have found a relationship between the strength of X-rays generated as material on the way into the hole is heated and the strength of jets blasting energetic particles back into space.

Jupiter’s Great Red Spot extending upward as it shrinks

14 March 2018 Astronomy Now

A new study indicates Jupiter’s Great Red Spot is drifting westward faster than before and extending upward, but analysis of historical data confirms it is shrinking overall and now is just slightly larger than Earth.

New instrument built to search for Earth-like exo-planets

14 March 2018 William Harwood

New high precision spectrometers are expected to help ground-based telescopes detect the presence of Earth-size planets orbiting other stars by measuring subtle changes in starlight caused by the gravitational tugs of orbiting exoplanets.
