Dark matter detectors designed to spot hypothetical dark matter particles have instead detected a signal from neutrinos produced by the sun. This 'neutrino fog' is both a milestone and a sign that these detectors may soon be overwhelmed by neutrinos, hindering their ability to detect dark matter.
Astronomers using Webb's MIRI instrument have directly imaged Epsilon Indi Ab, a gas giant several times the mass of Jupiter located around 12 light-years away from Earth. This is one of the coldest exoplanets to be directly detected, with an estimated temperature of 2 degrees Celsius.
Epsilon Indi is a nearby star system, notable for hosting a binary brown dwarf system, Epsilon Indi B. The system is discussed in detail, including its properties, the characteristics of the brown dwarfs, and the implications for understanding stellar evolution.
