Astronomers performed an extensive search for Dust Obscured Galaxies (DOGs) using data obtained from the Subaru Strategic Program with Hyper Suprime-Cam (HSC). The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbor a rapidly growing black hole in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes.
The shimmering colours visible in this NASA/ESA Hubble Space Telescope image show off the remarkable complexity of the Twin Jet Nebula. The new image highlights the nebula's shells and its knots of expanding gas in striking detail.
It is one of the most intriguing questions in astrochemistry: the mystery of the diffuse interstellar bands (DIBs), a collection of about 400 absorption bands that show up in spectra of light that reaches the earth after having traversed the interstellar medium. Despite intense research efforts over the last few decades, an assignment of the DIBs has remained elusive, although indications exist that they may arise from the presence of large hydrocarbon molecules in interstellar space. Recent experiments lend novel credibility to this hypothesis.
A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids. Researchers discovered this after conducting impact experiments simulating a meteorite hitting an ancient ocean.
Scientists have been fascinated by a series of unusual exploding stars - outcasts beyond the typical cozy confines of their galaxies. A new analysis of 13 supernovae is helping astronomers explain how some young stars exploded sooner than expected, hurling them to a lonely place far from their host galaxies.
