Charting the expansion history of the universe with supernovae
Sunday, 16 May 2021 23:01
An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven correct with future, higher-quality data from the Subaru Telescope and other observatories, these results could indicate still unknown physics working on the cosmic scale.

CATAL Rocket Lab's satellite launch from New Zealand site fails
Sunday, 16 May 2021 07:52California-based Rocket Lab said a launch of satellites from its facility in New Zealand failed Saturday.
The problem occurred during ignition of the Electron rocket's second stage, the company said in a statement.
The rocket was carrying two Earth-observation satellites for BlackSky, a global monitoring company.
"Today's anomaly occurred after 17 successful orbital launches of the Electron launch vehicle. With multiple launch vehicles currently in production, Rocket Lab is prepared for a rapid return to flight as soon as investigations are complete and any required corrective actions are in place," the statement said.
Rocket Lab said the rocket's first stage successfully parachuted into the ocean and crews were working to recover it. The company is trying to develop a capability to recover and reuse Electron first stages.
