Evidence for stars forming just 250 million years after Big Bang

Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO's Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the universe and the most distant galaxy ever observed by ALMA or the VLT.

Astronomers have found the fastest-growing black hole known in the universe, describing it as a monster that devours a mass equivalent to our sun every two days.


Unusual laser emission from the Ant Nebula

Astronomers have discovered an unusual laser emission that suggests the presence of a double star system hidden at the heart of the 'spectacular' Ant Nebula. The extremely rare phenomenon is connected to the death of a star and was discovered in observations made by European Space Agency's Herschel space observatory.


Levitation yields better neutron-lifetime measurement

Being repulsive can have its advantages. In the case of an experiment at Los Alamos National Laboratory's linear accelerator, a repulsive magnetic field and a clever detector system are allowing ultracold neutrons to be levitated so their actual lifetimes can be more accurately measured.
