With an eye on growing cost, NASA aims for 2025 launch of next ‘great observatory’

19 April 2017 Stephen Clark

NASA managers say the WFIRST mission, the next in the agency’s line of powerful observatories after the Hubble and James Webb telescopes, could cost around $3.2 billion after budgeting for a novel first-of-its-kind instrument to probe the make-up of planets around nearby stars and a bigger-than-expected launch vehicle.

The universe is expanding at an accelerating rate — or is it?

21 October 2016 Astronomy Now

Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace. Now, a team of scientists led by Professor Subir Sarkar of Oxford University’s Department of Physics has cast doubt on this standard cosmological concept.
