galaxies

University of Michigan astronomer Sally Oey studied a star-forming region in host galaxy, NGC 2366, which is a typical dwarf irregular galaxy. Image courtesy: Observatorio de Calar Alto, J. van Eymeren (AIRUB, ATNF) & Á.R. López-Sánchez

Dwarf galaxies use 10-million-year quiet period to churn out stars

Artist conception of early starbursting galaxies. The image is rendered from FIRE simulation data used for this research that can explain recent JWST results. Stars and galaxies are shown in the bright white points of light, while the more diffuse dark matter and gas are shown in purples and reds.

Cosmic Web Lights Up in the Darkness of Space

Spectroscopic observations reveal that Maisie’s galaxy, named after Steven Finkelstein’s daughter, was detected 390 million years after the Big Bang. That makes it one of the four earliest confirmed galaxies ever observed.

Astronomers confirm Maisie’s galaxy is among earliest ever observed

The first anniversary image from NASA’s James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disk, the makings of future planetary systems.

Webb celebrates first year of science with close-up on birth of sun-like stars

This deep galaxy field from Webb’s NIRCam (Near-Infrared Camera) shows an arrangement of 10 distant galaxies marked by eight white circles in a diagonal, thread-like line. (Two of the circles contain more than one galaxy.) This 3 million light-year-long filament is anchored by a very distant and luminous quasar – a galaxy with an active, supermassive black hole at its core. The quasar, called J0305-3150, appears in the middle of the cluster of three circles on the right side of the image. Its brightness outshines its host galaxy. The 10 marked galaxies existed just 830 million years after the big bang. The team believes the filament will eventually evolve into a massive cluster of galaxies.

Mystery of quasars solved: Most powerful objects in the Universe ignited by colliding galaxies

This artist's concept shows the brilliant glare of two quasars residing in the cores of two galaxies that are in the chaotic process of merging. The gravitational tug-of-war between the two galaxies ignites a firestorm of star birth.

Hubble unexpectedly finds double quasar in distant universe

Astronomers from an international team have used the James Webb Space Telescope to reveal, for the first time, the exact location of the source powering colliding galaxies. Curiously, this source lies outside of the main parts of the galaxies and is not visible at all in the ultraviolet or visible light observed with the Hubble Space Telescope.
