New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago.

NASA’s Webb Will Join Forces with the Event Horizon Telescope to Reveal the Milky Way’s Supermassive Black Hole
In its first year of operations, NASA’s James Webb Space Telescope will join forces with a global collaborative effort to create an image of the area directly surrounding the supermassive black hole at the heart of our Milky Way galaxy.
How disorderly young galaxies grow up and mature
Using a supercomputer simulation, a research team at Lund University in Sweden has succeeded in following the development of a galaxy over a span of 13.8 billion years.
‘Lonely cloud’ bigger than Milky Way found in a galaxy ‘no-man’s land’ by UAH physics team
A scientifically mysterious, isolated cloud bigger than the Milky Way has been found by a research team at The University of Alabama in Huntsville (UAH) in a “no-man’s land” for galaxies.
36 Dwarf Galaxies Had Simultaneous “Baby Boom” of New Stars
Three dozen dwarf galaxies far from each other had a simultaneous “baby boom” of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe. Galaxies more than 1 million light-years apart should have completely independent lives in terms of when they give birth to new stars. But galaxies separated by up to 13 million light-years slowed down and then simultaneously accelerated their birth rate of stars, according to a Rutgers-led study published in the Astrophysical Journal.
New evidence of how and when the Milky Way came together
New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy
Rutgers Expert Available to Discuss Supernova Discovery
New Brunswick, N.J. (April 21, 2021) – Rutgers University–New Brunswick astrophysicist John P. (Jack) Hughes is available for interviews on a supernova (exploding star) discovery published today in the journal Nature. The discovery, made with NASA’s Chandra X-ray Observatory, features…
Rutgers Expert Available to Discuss James Webb Space Telescope Science
New Brunswick, N.J. (Feb. 22, 2021) – Rutgers University–New Brunswick Professor Kristen McQuinn is available for interviews on the upcoming launch of the James Webb Space Telescope, its potential scientific impact and the leap forward it will provide in our understanding of the…
Evidence of Broadside Collision With Dwarf Galaxy Discovered in Milky Way
Astrophysicists announced today that a 3-billion year old merger between a dwarf galaxy and the Milky Way produced a series of telltale shell-like formations of stars in the vicinity of the Virgo constellation, the first such “shell structures” to be found in the Milky Way.
Massive halo finally explains stream of gas swirling around the Milky Way
Astronomers at the University of Wisconsin–Madison and their colleagues have discovered that a halo of warm gas surrounding the Magellanic Clouds likely acts as a protective cocoon, shielding the dwarf galaxies from the Milky Way’s own halo and contributing most of the Magellanic Stream’s mass.
How the Milky Way stole an enormous gas halo from our dwarf neighbours
There is a huge halo of gas circling our Galaxy with the mass of a billion Suns.
Galaxy Simulations Could Help Reveal Origins of Milky Way
Rutgers astronomers have produced the most advanced galaxy simulations of their kind, which could help reveal the origins of the Milky Way and dozens of small neighboring dwarf galaxies. Their research also could aid the decades-old search for dark matter, which fills an estimated 27 percent of the universe. And the computer simulations of “ultra-faint” dwarf galaxies could help shed light on how the first stars formed in the universe.
Thermonuclear blast sends supernova survivor star hurtling across the Milky Way
Bizarre white dwarf star shows evidence of a ‘partial supernova’ in observations using the Hubble Space Telescope, led by University of Warwick astronomers
Study: Dying Stars Breathe Life Into Earth
As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae. These ashes, spread via stellar winds, are enriched with many different chemical elements, including carbon.
Findings from a study published today in Nature Astronomy show that the final breaths of these dying stars, called white dwarfs, shed light on carbon’s origin in the Milky Way.
Peering under galactic dust, study reveals radiation at center of Milky Way
Thanks to 20 years of homegrown galactic data, astronomers at the University of Wisconsin–Madison, UW–Whitewater and Embry-Riddle Aeronautical University have finally figured out just how much energy permeates the center of the Milky Way.
The researchers say it could one day help astronomers track down where all that energy comes from. Understanding the source of the radiation could help explain not only the nature of the Milky Way, but the countless others that resemble it.
Intense Flash from Milky Way’s Black Hole Illuminated Gas Far Outside of Our Galaxy
Not long ago, the center of our galaxy exploded. Our primitive ancestors, already afoot in Africa, probably saw the resulting flare. Now Hubble detects that flash’s signature in a huge tail of gas orbiting the galaxy some 200,000 light-years away.
