The prolonged death of light from type Ia supernovae

more »
Three years after its explosion, a type Ia supernova continues to shine brighter than expected, new research finds. The observations suggest that the powerful explosions produce an abundance of a heavy form of cobalt that gives the heat from nuclear decay an extra energy boost. The work could help pinpoint the parents of type Ia supernovae -- a stellar explosion frequently used to measure distances to faraway galaxies -- and reveal the mechanics behind these explosions.

ATLASGAL survey of Milky Way completed

more »
A spectacular image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope has mapped the full area of the Galactic Plane visible from the southern hemisphere for the first time at submillimeter wavelengths and in finer detail than space-based surveys. The APEX telescope allows the study of the cold universe, a few tens of degrees above absolute zero.

LIGO's twin black holes might have been born inside a single star

more »
On September 14, 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. Such an event is expected to be dark, but the Fermi Space Telescope detected a gamma-ray burst just a fraction of a second after LIGO's signal. New research suggests that the two black holes might have resided inside a single, massive star whose death generated the gamma-ray burst.

Freefall achieved on LISA Pathfinder

more »

On Monday, the two cubes housed in the core of ESA’s LISA Pathfinder were left to move under the effect of gravity alone – another milestone towards demonstrating technologies to observe gravitational waves from space.
