ASTRO 3D: Researchers hunt for a 12-billion-year-old signal that marks the end of the post Big Bang “dark age”.
An Australian scientist has created the most detailed map ever of clouds of high-velocity gas in the Universe around us. The map covers the entire sky and shows curious clouds of neutral hydrogen gas that are moving at a different speed to the normal rotation of the Milky Way.
Astronomers have shed fresh light on the importance of hydrogen atoms in the birth of new stars. Only hydrogen molecules are thought to directly fuel star formation but research published today shows there are more hydrogen atoms than molecules even in young galaxies that are making a lot of stars.
