Telescopes have had their sensitive instruments honed in on an astronomical object resembling a Christmas Tree and 2,500 light years from Earth.

The first experiments involving the most powerful laser in the United States, the Zetawatt-Equivalent Ultrashort pulse laser System (ZEUS), have begun.

The presence of 'cool fire', an entirely new class of fire, has been documented on the International Space Station (ISS).
