Image - The atomic structure of pyrene molecules (upper left and upper right) are represented in an artist's rendering of an asteroid belt. A new study shows chemical steps for how pyrene, a type of hydrocarbon found in some meteorite samples, could form in space.

The telescope’s 2-meter corrector barrel will be removed and replaced with a new corrector barrel for the Dark Energy Spectroscopic Instrument. DESI’s installation will begin soon at the telescope.

The yellow-red glow at center shows a hydrodynamic simulation of quark-gluon plasma created in particle collisions. (Credit: Berkeley Lab)
