Astronomers have combined 2,884 Type Ia supernovae -- which are used to measure cosmic distances -- with cosmic microwave background and galaxy-mapping data, deepening cracks in the standard ‘cosmological constant’ model.

Stoke Space announced Tuesday that it has raised another significant round of funding, $1 billion, as it makes a final push toward its debut launch next year. The Washington-based launch company also revealed plans for a larger medium-lift vehicle.
With the Series E funding round, co-led by Point72 Ventures and Spark Capital, Stoke Space brought its total amount of capital raised to $2.3 billion, a staggering amount for a company that has yet to attempt an orbital launch.
The quantity of new funding will enable the company to accelerate work on a larger "Block 2" version of the Nova rocket, capable of lifting 15 metric tons to low-Earth orbit in a fully reusable configuration, said Stoke co-founder and Chief Executive Andy Lapsa.

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae. An international team of astronomers analyzing observations from NASA’s Fermi Gamma-ray Space Telescope has found what appears to be the first convincing detection of gamma rays from a rare type of extraordinarily bright stellar explosion known as a superluminous supernova.
