How to Shape a Spiral Galaxy

Our Milky Way galaxy has an elegant spiral shape with long arms filled with stars, but exactly how it took this form has long puzzled scientists. New observations of another galaxy are shedding light on how spiral-shaped galaxies like our own get their iconic shape.

Some of the most dramatic events in the universe occur when certain stars die -- and explode catastrophically in the process.

For decades, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars--the most mysterious objects in the universe.

In a paper on the preprint site ArXiv and soon to be published in the Astrophysical Journal, researchers present the first analysis of data from a new configuration of the MWA designed specifically to look for the signal of neutral hydrogen, the gas that dominated the universe during the cosmic dark age.

Giant Magnetic Ropes in a Galaxy's Halo

This image of the "Whale Galaxy" (NGC 4631), made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA), reveals hair-like filaments of the galaxy's magnetic field protruding above and below the galaxy's disk.

We report the discovery of WISE2150-7520AB (W2150AB): a widely separated (~ 341 AU) very low mass L1 + T8 co-moving system.

A radio telescope in the Western Australian outback has captured a spectacular new view of the centre of the galaxy in which we live, the Milky Way.

Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to touch up the cosmological model.

Two peacock-shaped gaseous clouds were revealed in the Large Magellanic Cloud (LMC) by observations with the Atacama Large Millimeter/submillimeter Array (ALMA).

Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago.

NICER Catches Record-setting X-ray Burst

NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on Aug. 20.

Scientists from Germany and the United States have unveiled the results of a newly-completed, state of the art simulation of the evolution of galaxies

Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego's Alison Coil, Rhodes College's David Rupke and a group of collaborators from around the world made a novel discovery.

Hubble Captures Cosmic Face

In celebration of Halloween, this new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face.

For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars.

New measurements of the rate of expansion of the universe, led by astronomers at the University of California, Davis, add to a growing mystery: Estimates of a fundamental constant made with different methods keep giving different results.

A team of astronomers including assistant professor Kate Whitaker at the University of Massachusetts Amherst reports today that they have by chance discovered faint traces of a huge galaxy never seen before, dating from the early universe.

On a typical day at the world's biggest laser, the National Ignition Facility (NIF) in Livermore, California, you can find scientists casually making star-like conditions using 192 high-powered lasers.

"Weather" in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge.

The birthplaces of planets are disks made out of gas and dust.
