Introduction Natural bitumen, a dense, viscous, semi-solid form of petroleum composed of aliphatic and aromatic hydrocarbons, asphaltenes, resins, sulphur compounds, and trace metals constitutes a ...

When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small ...

By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...

THE Astrophysical Journal for February contains some papers of the highest interest, touching small variations in the wave-lengths of spectral lines and the causes which produce them. These are stated ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced ...

Using spectral data from the Hobby-Eberly Telescope at McDonald Observatory, astronomers have produced the most detailed 3D map yet of faint cosmic structures from 9-11 billion years ago, revealing ...
