In addition to being an impressive observational achievement, the detection provides insight into the early stages of the evolution of supernova remnants and th...
The fingerprints of molecules in space
Jul 02, 2018 (SPX)
In addition to stars, galaxies are populated by regions that contain gigantic dust and gas clouds. Such regions, making up the interstellar medium (ISM), act as...
NASA completes Webb Telescope review, commits to launch in early 2021
Jun 28, 2018 (SPX)
A report issued by the review board addresses a range of factors influencing Webb's schedule and performance, including the technical challenges and tasks remai...
Frankfurt physicists set limits on size of neutron stars
Jun 28, 2018 (SPX)
Neutron stars are the densest objects in our universe, with a mass larger than that of our sun compacted into a relatively small sphere whose diameter is compar...
Planet formation starts before star reaches maturity
Jun 28, 2018 (SPX)
In recent years, astronomers have discovered numerous planetary systems around other stars. Almost every star is likely to have at least one planet orbiting it....
Grease in space
Jun 28, 2018 (SPX)
Organic matter of different kinds contains carbon, an element considered essential for life. There is though real uncertainty over its abundance, and only half ...
First known interstellar object gets unexpected speed boost
Jun 28, 2018 (SPX)

A galactic test will clarify the existence of dark matter
Jun 26, 2018 (SPX)
Using one of the fastest supercomputers in the world, the scientists have simulated the matter distribution of the so-called satellite "dwarf" galaxies. These a...
Citizen scientists developing expertise on galaxy images
Jun 26, 2018 (SPX)
